A new week began. Marcus entered the school. 1 , he cried out, "What happened to the stadium?" Someone had painted faces on the stadium wall!

All students were whispering with 2 about the graffiti(涂鸦). Possible explanations spread likewildfire around the school.

Later, when Brian cleaned the blackboard, Marcus suddenly spotted the paint on his hands. He 3 that it was Brian who did it. After school, Marcus followed Brian and 4 on what he was doing. When Brian opened his locker, Marcus saw small cans of paint!He decided to 5 it to Mr. Johnson.

The next morning, Brian was called to the principal's office. The moment Mr. Johnson 6 asked about the graffiti, Brian cried. 7 , Brian explained that he liked to paint, but he couldn't join the art club because he had to go 8 home after school to babysit his little brother. "I'm sorry. I'll clean the stadium," he sobbed.

Though angry at first, Mr. Johnson began to soften as he realized how 9 Brian was. "Brian, painting graffiti on school walls is a very serious matter.Of course you should clean and 10 the wall." Mr. Johnson paused, "11 I must say, those paintings are quite good. Did you do it alone?" Brian nodded, "Yes. I'm good at painting."

Mr. Johnson thought for a moment before making a (n) 12 . "Well," he said, "some teachers suggested that we hire a local artist to paint our school mascot on the school wall. Would you like to participate in that?"

"Really?" Brian hesitated, 13 to believe it.

"Yes, but it's hard work, and we can consider it part of your 14 ," Mr. Johnson said, trying to hide his 15 as he picked up the phone.

Color is in everything we touch, taste, smell and feel. It evokes(唤起) emotion without any thought. We are all familiar with it, but do you know the following facts?

Silver will save your life. When buying a new car and finding yourself facing various choices, you can't think clearly. Your best choice is to go with silver. Silver-colored cars are least likely to be involved in a car accident.Another reason is the silver color's ability to have a look of cleanliness.

Tough prisoners and crazy patients? It is the color commonly used to help calm down those who are out of control.So it surely has a useful place and a purpose, other than decorating a dress or Barbie's dream house.

Yellow makes you hungry. Yellow and orange are not recommended for use in kitchens, as they have apositive influence on your appetite.I'm not normally one for conspiracy(阴谋) theories- but perhapsthere's something in it for them if we remain ignorant of yellow's effects.

Color is an imaginary friend. Technically, it's all in our heads: color does not exist at all.So, it you start a heated debate over color combinations with someone that you are certain has a low IQ or is just color-blind, remember it's a pointless argument and you should drop it instantly. You're both wrong.

A. Pink comforts the nerves.

B. Blue is the most common favorite color.

C. They are most noticeable on the road and in low light.

D. Yellow-colored walls seldom leave us wanting more food.

E. It can be the focus of our careers, our lifestyle and the fun we have.

F. Then where would our restaurant owners be without the clever tricks?

G. Color tries to make sense of the huge amount of information from the outer world.

Humans are not the only ones who underwent self-domestication. So did our close relatives, the bonobos,and the species we call our best friend. A tiny proportion of the genome(基因组) differentiates dogs from wolves,and yet millions of dogs are comfortably curled up in our homes, while wolves move around at the edge of extinction.

When our research group began its work almost 20 years ago, we discovered that dogs also have extraordinary intelligence: they can read our gestures better than any other species. Wolves, in contrast, are mysterious and unpredictable. Their home is the wilderness, and that wilderness is reducing.

But not so long ago the evolutionary race between dogs and wolves was so close, it was unclear who would win. Dogs, in fact, did not descend from wolves. Instead, dogs and wolves shared a wolf-like ancestor.

Folklore supposes that humans brought wolf puppies into camp and domesticated them. Or as wolf expert David Mech wrote in 1974,"Evidently early humans tamed wolves and domesticated them, eventually selectively breeding them and finally developing the domestic dog from them." But this story has not held up. Taming an animal occurs during its lifetime. Domestication happens over generations and involves changes to the genome.

So how did wolves turn into dogs? Back in the Ice Age, as our human populations grew more sedentary, we probably created more rubbish, which we then dumped outside our camps. These leavings would have included tempting pieces of food for hungry wolves. Notevery wolf would have been able to scavenge(觅食，拾荒),however. These animals would have had to be unafraid of humans, and if they displayed any aggression toward us,they would have been killed.

After generations of selection for friendliness without intentional selection by humans, this special population of wolves would have begun to take on a different appearance. Coat color, ears,

tails: all probably started to change.

Animals that could respond to our gestures and voices would be extremely useful as hunting partners and guards. They would have been valuable as well for their warmth and companionship, and slowly we would have allowed them to move from outside our camps to our firesides. We did not domesticate dogs. The friendliest wolves domesticated themselves.

Last year, 138,000 San Francisco residents used Airbnb, a popular app designed to connect home renters and travelers. It's a striking number for a city with a population of about 850,000, and it was enough for Airbnb to win a major victory in local elections, as San Francisco voters struck down a debatable rule that would have placed time restrictions and other regulations on short-term rental services.

The company fiercely opposed the measure, Proposition F, with a nearly $10 million advertising campaign. Italso contacted its San Franciscan users with messages urging them to vote against Proposition F.

Most people think of Airbnb as a kind of couch-surfing app. The service works for one-night stays on roadtrips and longer stays in cities, and it often has more competitive pricing than hotels. It's a textbook example ofthe"sharing economy", but not everyone is a fan.

The app has had unintended consequences in San Francisco. As the San Francisco Chronicle reported lastyear, a significant amount of renting on Airbnb is not in line with the company's image: middle-class familiesputting up a spare room to help make ends meet. Some users have taken advantage of the service, using it to turn their multiple properties into vacation rentals or even full-time rentals. Backers of Proposition F argued that this trend takes spaces off the conventional, better-regulated housing market and contributes to rising costs.

"Thefact is, widespread abuse of short-term rentals is taking much needed housing off the market andharming our neighborhoods,"said ShareBetter SF, a group that supported Proposition F. Hotel unions haveprotested the company's practices in San Francisco and other cities, saying that it creates an illegal hotel system.

San Francisco is in the middle of a long-term, deeply rooted housing crisis that has seen the cost of livingexplode. Actually, explode is a generous term. The average monthly rent for an apartment is around $4,000.Located on a narrow outcropping of landoverlooking the bay, San Francisco simply doesn't have enough space to accommodate the massive inflow of young, high-salaried tech employees flocking to Silicon Valley.

As the Los Angeles Times reported, some San Francisco residents supported the measure simply because itseemed like a way to check a big corporation. Opponents of Proposition F countered that the housing crisis runsmuch deeper, and that passing the rule would have discouraged a popular service while doing little to solve the city's existing problems.

As parents, we always hope to develop character traits in our children that will enhance their success in life. When our daughter Meegan, the eldest of five children, lost her front tooth at the age of six, we found the following note wrapped around the tiny tooth.

Der Tooth Fairy,

Pleze leve me yor majik wand(杖). I want to be a tooth fairy, too.

Luv Meegan

Recognizing potential leadership skills, precious opportunity and the teachable moment,the "Tooth Fairy" left the following note for little Meegan:

Dear Meegan.

I have worked hard to be a good Tooth Fairy and I love my job. You are too young for the job just now. so I cannot give you my wand. But there are some things that you can start to do to prepare yourself for the job.

1）Always do your best in every job that you do.

2）Treat all people as you wish to be treated.

3）Be kind and helpful to others.

4）Always listen carefully whenever people speak to you. I will interview you one day when you are older and ready for the job

Good Luck, Meegan!

The Tooth Fairy

Meegan was thrilled at the response from the Tooth Fairy. She took the message to heart and carefully followed the instructions, always working to improve as she grew. Her character, her strength and her leadership skills grew right along with her. After graduating magna cum laude(以优秀成绩) from college. Meegan accepteda challenging management position. She excelled, and by age 27, she was the top manager of the company.

One day Meegan and I were talking about her success. She told me that the company president had once asked her what influences had motivated her toward success.

"What did you tell him?" I asked.

She replied. "My parents, my teacher and my friends. And, of course, the Tooth Fairy!"

A long time ago, when I worked in Ahmedabad, we would often drive to Mount Abu for short trips—it took us anywhere between seven to eight hours to drive up. That year, my close relatives were visiting from Lucknow during the holidays, and we made a plan to visit Abu for three days. Since there were seven of us, including my brother's family who also lived in Ahmedabad, we hired two cabs. We picked ourselves into the vehicles, stacked (堆放) our luggage on the carriers on top and started out.

A good time was badby all, and soon it was time to return. During the journey back, we stopped at a Dhabafor tea and snacks near the Mehanadistrict. That's when I noticed suddenly that the rope with which the luggage was tied on and of the carriers had come loose and one of the suitcases was missing. It must have fallen off somewhere along the way.

Although it didn't contain any valuables—just clothes and some cash, we decided to retrace our steps, drawing back four kilometres, looking for the bag. But luck wasn't our friend: we could not locate it and returned to Ahmedabad depressed.

After about a month, one day, while in my office, I got a call from my assistant that a certain Mr. Shah wanted to see me. I was in the middle of a meeting so he was asked to wait. After I got done, I called him into my office.

I was looking after the development of small industries in the state at the time, so my immediate query was. "How can we help you? Do you want to set up an industry or are you facing any issues in your enterprise?"

To which he said, "No, sir. I have not come for any official help. It is a personal matter. Did you lose something recently?"

Of course, it all came back to me and I told him about the lost suitcase from the cab back from Mount Abu a month ago.

Good Habits, Good Heal

The day starts early for Shi Xiaogang, a wildlife ranger (护林员) at the Wolong National Nature Reserve in Southwest China's Sichuan province. He monitors the population of giant pandas and conducts long-range patrols (巡逻) in some of the most extreme environments, is a challenging and, often, dangerous job.

(cover) about 200,000 hectares, Wolong National Nature Reserve is home to one of the largest remaining giant panda populations in China. Thanks to the rangers' like Shi's efforts, number of wild giant pandas in the reserve has increased from 104, in 2015, to 149 today. In 2016, the International Union for Conservation of Nature (announce) that the giant panda's status had been changed from "endangered" to "vulnerable" on its Red List of Threatened Species.

As well as "the home of giant pandas", the reserve is (wide) known as a "bio-gene bank". It features a great number of threatened species of plants and animals, including other famous (creature), such as the red panda, snow leopard and clouded leopard among the 121 species of mammals (哺乳动物) (record). There are also 392 bird species.

To mark the rangers'hard work and contribution to wildlife (protect) in the reserve, last year, 20 rangers (recognize) with special commendations (表扬) at an online award ceremony for the IUCN World Commission on Protected Areas'International Ranger Awards.

The commission speaks highly of their work, saying that they help stop biodiversity loss and protect the important ecosystems that serve natural solutions to climate change and other global challenges.

I used to believe in the AmericanDream, which meant a job, a mortgage (按揭), credit cards, success. I wanted it and worked toward it like everyone else, all of us 1 chasing the same thing.

One year, through a series of unhappy events, it all fell 2 .I found myself homeless and alone. I had my truck and $ 

56.I 3 the countryside for some place I could rent for the 4 possible amount. I came upon a shabby house four miles up a winding mountain road 5 the Potomac River in West Virginia. It was 6 ,full of broken glass and rubbish. I found the owner, rented it, and 7 a corner to camp in.

The locals knew nothing about me, 8 slowly, they started teaching me the 9 of being a neighbor. They droppedoff blankets, candles, and tools, and began 10 around to chat. They started to teach me a belief in a 11 American Dream—not the one of individual achievement but of 12 .

What Ihad believed in, all those things I thought were 13 for a civilized life, were nonexistent in this place. 14 on the mountain, my most valuable possessions were my 15 with my neighbors.

Four yearslater, I moved back into 16 .I saw many people were having a really hard time, 17 their jobs and homes. I managed to rent a big enough house to 18 a handful of people. There are four of us now inthe house, but over time I've had nine people come in and move on to other places. We'd all be in 19 if we hadn't banded together.

The American Dream I believe in now is a shared one. It's not so much about what I can get for myself; it's about 20 we can all get by together.

We have featured people who lost weight by following many different methods. Some focused strictly oneatingwell. Here are some lessons you can learn from those people. 

One thing most of our wellness winners had in common was a turning-point moment. For San Boeuf, her journey started when her unhealthy weight was threatening her dream of becoming a mother. She focused on her goal of being healthy enough to have kids. 

Many of our winners relied on technology to assist them on their weight-loss journeys. There 're numerous apps, devices and online communities. Sousing all the tools available makes a difference, whether those are apps to log your food, smart devices to track your exercise, or online communities to find the support you need. 

Losing a significant amount of weight is a long process. All of the wellness winners experienced struggles along the way but managed to stay or get back on track and maintain their healthy habits. Susan Elizabeth Chaney struggles with an eating disorder after losing a significant amount of weight. 

Choose a diet you can stick with. In other words, the specific plan matters a lot less than the effort you put into it. Some used intermittent fasting( 间歇性禁食), while others found eating smaller meals throughout the day to be more sustainable.

A．They can help people lose weight.

B．Set a healthy lifestyle for yourself.

C．There's no magic diet for wellness winners.

D．There are struggles and setbacks along the way.

E．But finding help and support made a big difference.

F．Along with lots of hard work, she managed to lose 167 pounds.

G．Others found a love of exercise—or a healthy combinationsof both.

A small group of paleontologists (古生物学家) recently discovered 10 species of ancient mammals previously unknown to science with the help of an enormous number of helpers at their dig site: ants. 

The study of ancient mammals throws new light on the diversityof mammals that existed in North America around 33 million to 35 million years ago, when the climate was changing dramatically. It also pays attention to the harvester ants, with which researchers have long had a love-hate relationship. "The ants are not fantastic when they're biting you," said Samantha Hopkins, a professor of Earth Sciences at the University of Oregon. "But I've got to appreciate them because they make my job a whole lot easier."

Most species of harvester ants live in subterraneancaves that sit beneath a small hill of dirt. They strengthen the dirt by covering it with bits of rock and other tough materials. The ants have been known to travel over a hundred feet from their caves and to dig six feet deep in pursuit of materials that help secure their caves. The materials include fossils. Harvester ants can carry materials 10 times to 50 times the weight of their body, although they do not weigh very much, so the heaviest fossil they can collect weighs less than the average pill. 

Given the size, harvester ant hills are hot spots for what scientists call microvertebrate(微型脊椎动物) fossils, which are animal fossils too small to see without a microscope. For over a century, scientists like Dr. Hopkins have found sediment (沉积物) off the sides of harvester ant hills in search of these fossils, making it easier to find large numbers of fossilized mammal teeth without spending hours in the field sifting through sand and dirt.

The first week of September was a week that I had been expecting all summer. I didn't want summer to end. But I was excited about going to high school for my first week.

When I got to school in the morning on the first day I realized how large the school was, and how many students went there. I ended up in the wrong classroom because of the size of the school. Luckily, a kind senior showed up and guided me to my homeroom before I was late. I was happy to see that in a class of unfamiliar (不熟悉的) faces, the only open seat was next to my good friend, Casey. My science teacher seemed like a good teacher. She was exciting and fun.

After finishing four periods without too much of a challenge, I didn't feel too bad about ninth grade.

However, the fifth period changed everything.

The first week passed quickly.

Adam is a freshman at senior high school. (go) from junior high school to senior high school is really big challenge to him. So he felt a little (confuse) at first.

First, he had to choose the suitable courses. (lucky), his adviser helped him recommended that he should sign up for advanced literature.

He had to choose extra-curricular activities, too. To his (disappoint), when he tried to join the school football team, the coach refused him. However, he didn't lose hope. He'll find a way (improve) by himself so that he can join the team next year.

He knows he'll have to study (hard) as a senior high school student and get used to being responsible a lot. He'll be well prepared for university or whatever else (come) in the future.

When I first met Sarah, all I noticed was her drool (口水) running from the corner of her mouth. As Mrs. Wagner pushed the wheelchair towards me, I felt 1 . Why did she sit beside me?

For the entire morning, I was uneasy. Eventually, I nerved 2 to ask Mrs. Wagner, "Mrs. Wagner, can I have my 3 changed?"

She patted (拍) my shoulder gently and said, "Natalie, Sarah 4 our care. Try it."

Why? I didn't need a deskmate with running drool! I decided to 5 Sarah, at three o'clock, our 6 teacher came and said, "Kickball time! Put on your gym shoes." As I bent (弯腰) over to tie my shoes, Sarah caught my attention and I wondered 7 it feels to never walk. My 8 felt tight.

Mrs. Wagner asked me, "Natalie, 9 Sarah cannot kick, she can throw balls. Would you help her in the gym class?"

I had to 10 and push Sarah to the playground.

Firstly, Matt kicked the ball and it came to me. I handed it to Sarah and she 11 it, which just struck Mike's heel!

"You got him out!" I shouted. Sarah 12 happily. Then I laughed, too. The rest of the game was 13 and we all enjoyed ourselves.

At the end of the day, Sarah read a journal entry to us, "My 14 day of school went well. I had fun playing kickball. I made a nice new friend, Natalie."

Sarah 15 at me. I didn't notice her drool. What I saw was a new friend, a friend I had almost missed.

Parents with high expectations for their children are nothing new to Chinese kids. However, people often don't realize that children also have expectations of their parents.

China Youth & Children Research Center did a survey in 2018 on this topic in the United States, Japan, South Korea and China. It showed that 83.8 percent of Chinese children want to be friends with their parents.

But the reality is different. Respecting one's elders and the concept of hierarchy are preventing parents from becoming friends with their children.

. As children, what can you do to create a pleasant atmosphere at home and make friends with your parents?

Act like an adult.

If you want your parents to give you more freedom, you should show them that you're ready to be treated differently. For example, learn to use self-control. Show them that you can manage your time well.

US psychologist Carl E. Pickhardt wrote in Psychology Today that sharing feelings with our parents can lead to positive changes, while not sharing them can cause misunderstandings.

Do something nice or helpful for your parents. For example, help them with some home chores, make them gifts or teach them some computer skills. Their trust in you will grow.

A. Open your heart.

B. Traditional Chinese values might be a reason.

C. Be a good student at school.

D. Both parents and children should make efforts to create friendship in the family.

E. Care for your parents.

F. Chinese parents tend to spoil their children.

G. What expectations do Chinese children have for parent-child relationships?

Have you ever heard someone say "breakfast is the most important meal of the day" or explain to you why it's vital to start the day with a healthy breakfast? It seems that this meal, for many of us, is necessary for our day to start well, but is it really that important?

The word "breakfast" comes from "breaking the fast (禁食期)" — the idea of ending the period in which we don't eat during the night. The regeneration process that takes place while we are sleeping consumes some of our natural food reserves in our bodies. Breakfast gives us an opportunity to replenishthose reduced stores of things like protein and calcium. So, in that way, a healthy breakfast makes sense.

There are also many studies which seem to relate a state of obesity(肥胖) to skipping breakfast. In fact, it leads many health experts to conclude that a healthy breakfast not only regulates but also loses weight. In a U.S. study, 50,000 people were observed over seven years, and those who ate a healthy breakfast were found to have a lower BMI, which seems to suggest that breakfast may indeed help people maintain a healthy weight. 

But it might not be as simple as that. Some experts, like Alexandra Johnstone, professor of the University of Aberdeen, suggest those who skip breakfast might be less aware of healthy diets, and people who eat breakfast might have a healthier lifestyle overall — exercising and not smoking, for example. And with the popularity of intermittent (间歇的) fasting to lose weight, there may also be some benefits to skipping breakfast. Intermittent fasting can improve blood sugar control, insulin sensitivity, and lower blood pressure. 

So, while breakfast has its benefits, it might not be the most important meal. It seems that a healthy lifestyle with a balanced diet might be more important for us than just one single meal.

Here are some pet-friendly universities in the UK and US.

University of Illinois

Students are allowed up to two pets in each apartment, as well as a fish tank of no more than 50 gallons.

To keep a pet, you will need to get approval from the Family & Graduate housing department at the University of Illinois. You will have to provide proof that your pet is up to date with its vaccinations(疫苗), and pay a monthly US$30 pet fee, which is non-refundable(不可退款的).

Your pet can't be left for extended periods of time, and if there's evidence that you've left it alone due to vacation or illness, the university may remove it.

Harvard University

With as many as 12 pet-friendly apartments, Harvard is a very pet-friendly university. It allows students to have fish in a tank of no more than 50 gallons, except for Harvard's Cronkhite Graduate Center.

In Harvard's pet-friendly apartments, you're allowed: one cat or one dog, which can't be over 40 pounds when fully grown. At most, two pet birds.

University of British Columbia Students can take advantage of the university's B. A. R. K program, which uses the calming power of therapy dogs to help them.

B. A. R. K started at the University of British Columbia, after an assistant professor called Dr. John-Tyler Binfet noticed that he couldn't walk across campus without students running over to play with his dog, Frances. The students told him they were homesick and missed their pets, which encouraged Binfet to establish B. A. R. K as a way of fighting their loneliness.

University of Oxford

The University of Oxford is famous for its resident pets, who happily wander around college grounds. Many Oxford colleges have their own tortoise and take part in the annual Corpus Christi tortoise race.

Although you are not allowed to keep your own pet as a student, several Oxford colleges hold dog petting and walking therapy sessions.

The easy way out isn't always easiest. I learned that lesson when I decided to treat my father to a special meal. I glanced through the cookbook and chose a menu which included homemade bread. Knowing the bread would take time, I started on it as soon as he left for work. 

As I was not experienced in cooking, I thought if a dozen was good, two dozen would be better, so I doubled everything. As Dad loved oranges, I also opened a can of orange and poured it all into the bowl. Soon there was sticky dough (面团) covered with ugly yellowish marks. Realizing I had been defeated, I put the dough in the rubbish bin outside so I wouldn't have to face him laughing at my work. 

I went on preparing the rest of the meal, and, when Dad got home, we sat down to Cornish chicken with rice. He tried to enjoy the meal but seemed disturbed. Twice he got up and went outside, saying he thought he heard a noise. The third time he left, I went to the windows to see what he was doing. 

Looking out, I saw Dad standing about three feet from the rubbish bin, holding the lid up with a stick and looking into the container. When I came out of the house, he dropped the stick and explained that there was something alive in the rubbish bin. Picking up the stick again, he held the lid up enough for me to see. I felt cold. But I stepped closer and looked harder. 

Without doubt it was my work. The hot sun had caused the dough to double in size and the. fermenting yeast (酵母) made the surface shake and sigh as though it were breathing. I had to admit what the "living thing" was and why it was there. I don't know who was more embarrassed by the whole thing, Dad or me.

My dad tapped me gently on the shoulder, and we went inside. 

At a party three months later, everyone wanted to try my bread.
