Some animals learn to remember information in their minds .

Numbers are very important to us, and we see them every day. Last week, our math teacher asked us to c the money for our class party budget. Everyone took out their n and wrote down each expense clearly: 20 yuan for snacks, 15 yuan for drinks, and 10 yuan for decorations. After finishing, we c our results together. I made a small mistake at first, but Lucy is a t girl—she is good at using numbers. Her answer was e right: the total was 45 yuan! All of us in the class agreed that numbers help us avoid mistakes. We also use numbers e, such as airports, supermarkets. Without numbers, life would be messy. So let's learn to use numbers well. They are our helpful friends!

One big problem is wildfires. For example, because of the hot, dry weather, big fires burned in 2020 and 2021. It may take much longer for both humans and nature to recover (恢复).

These beetles lived peacefully with sequoias in the past, but now they're attacking them. They dig holes in the highest parts of the tree. The beetles are small, but there are so many of them that they can kill a giant tree in just six months!

Scientists are trying to help. However, it is impossible to climb every tree and look at its highest part. So now, scientists are using robots and satellites to record beetle activity over large areas of forest. In this way, they can help protect more trees.

A. Sadly, about 20% of the world's 75,000 sequoias were killed.

B. And slowly these insects move down the trunk, eating the tree as they go.

C. Another problem comes from bark beetles, the tiny insects.

D. But they are in trouble.

E. They climb the trees to look for beetle holes.

Almost all animals need to sleep to stay healthy. But sleeping can be dangerous because other animals may hunt sleeping animals. To help them stay safe, animals have many different ways of sleeping. Some of these ways may surprise you!

Some seabirds can sleep while they fly. These large birds spend most of their lives over the ocean. They are in danger on the water, but they are safe in the air. They glide (滑行) for many hours without moving their wings up and down. Sometimes they sleep while they glide.

A dolphin sleeps with just half its brain at a time. It must stay awake to breathe and to watch for danger. Dolphins can swim without sleep for two months to stay safe. Ducks sleep with just half their brains, too. These ducks often sleep in a line. The ducks at both ends help keep the group safe. They keep one eye open to watch for danger. The ducks in the middle sleep with both eyes closed.

Seals breathe air, but that doesn't stop them from sleeping underwater. They hold their breath and dive deep to sleep for up to twenty minutes at a time. Some fish make their own sleeping bags. They make a big bubble and sleep inside it. It also keeps other animals from smelling them. If an animal hits the bubble, the fish swims away quickly.

Hello! I'm Li Bing, an ancient engineer from Qin State. Let me tell you about Dujiangyan—the world's oldest working water system. We built it over 2,200 years ago!

What was our problem?

Long ago, people in Sichuan faced a big problem. In rainy seasons, the Min River often flooded their farms. But in dry seasons, there was no water for crops.

How did we solve it?

Instead of building dam walls to block the water, we let the water run its own way.

First, my team had to cut through Mount Yulei to make the Baopingkou (宝瓶口). It led part of the Min River to run east. Without any machines, we could only use fire and freezing water to break the rocks open. This took us eight years. Then we built the Yuzui (鱼嘴) to divide the river into two parts. One part carried water to farms, while the other stopped floods. The next problem was the sand and stones in the Min River. We built Feishayan (飞沙堰) to wash them away with water power and keep the system clean.

Why can it last so long?

It is our smart design. We made the deeper Inner River and the lower Feishayan, so the system could control the water during the flood and dry seasons. And for over 1,000 years, workers clean and take care of it every year.

What does it bring?

This is our greatest contribution: A river system grew. It not only made the land around Chengdu rich, but also waters over 7,700 square kilometers of farmland, and feeds 30 million people in 8 cities today. Besides, it is now a UNESCO World Heritage Site. To remember my son and me, locals celebrated with a traditional festival every spring. Also, Erwang Temple was built to honour us.

What is the key to building it?

Actually, we just listened to the water and followed its nature.

The next morning, Lily found a small notebook on her desk. Inside were colorful drawings: a maths problem turned into a friendly monster saying "Solve me!" Next to it was a step-by-step guide written in her dad's lovely handwriting.

For two weeks, her parents worked secretly without telling her. After dinner, her mom would draw funny characters for each maths concept or idea while her dad searched online for easy explanations. They filled the notebook with funny sentences too. "Why is six afraid of seven? Because seven ate nine!..." Words like these made Lily laugh even during practice.

On the test day, Lily felt nervous until she remembered the notebook's smiling sun drawing. When she saw a difficult question, her dad's notes appeared in her mind, "Break it into small steps." She passed the test with a B!

That evening, Lily opened the notebook again. This time, she found a new page. Her mom had drawn a big heart with the words, "We knew you could do it. You're always our smart girl!"

Lily hugged the notebook close and smiled. It wasn't just a study guide—it was her parents' love that helped her through difficulties.

Early in September, I planned to run for the monitor in the class election. I enjoyed speaking in front of many people and was always friendly to others, so I thought it was1 for me to win.

I kept preparing in the following2, thinking about everything for my election. I put up my posters in the classroom. I also spent hours on my3, saying that when anyone of my classmates had a(n)4, he/she could always ask me for help. I felt quite sure about my winning because I prepared it5.

But when I gave my long talk on Election Day in late September, it wasn't what I imagined. Things were6. During my talk, most of my classmates were not listening. They were just doing their homework. But when it was time for another classmate, everyone7 his name and cheered. His talk was much8 than mine, but with a lot of helpful ideas. Soon he finished his talk. At that moment, I knew I was out.

The next day, at school, I just didn't want to hear it while my class were still talking about the election. Later things got better. People9 about the election and talked to me just as they did before.

I didn't win, but I wasn't10 putting so much time and energy into the election. I have learned a lot. Things aren't always going the way we want. We should learn to face these moments and work harder to make ourselves better!

After a5 afternoon, Ted created a new invention. He took apart a broken wood mixer (搅拌器) and then connected it to a motor (电动机). It was able to stir things by itself6 it got power from the motor.

A: Excuse me!? I am new here.

B: The post office? It is in front of a supermarket. You can walk there because it isn't far from here.

A:?

B: Of course. Just go along this street until you reach the second crossing. Turn left. Go straight until you find the library. Then turn right at the library. After that, keep going and you can find the post office is on your left.

A: Wow, that's so far.?

B: You can take the NO.44 bus there. That will be faster.

A: OK..

B: You are welcome.?

A: Because I want to buy some postcards for my friends.

B: Oh, I see.

Lucy is a student in Grade 9. She manages her time (wise). Every morning, she makes some (plan) before school starts. For example, she decides (finish) math homework before dinner and review English during breaks.

Her room is always clean tidy. She cleans her room every day. There is desk in her room. On the desk, books are order. She thinks that the tidy desk helps (she) focus better.

Lucy also balances study and fun. When she feels tired, she listens soft music or does jumps for five minutes. These small breaks refresh her mind. On weekends, she often (visit) the library to borrow storybooks. Reading not only makes her feel (relax) but also improves her (write) skills. Last month, she was praised by the teacher. Why? Because she (use) creative ideas from those books in her writing.

So far, she (follow) her self-management habit for three years. Though challenges appear sometimes, she never gives up. "I (keep) trying in the future," she says. "Self-management makes me (strong) than ever before." Let's learn to manage our study and life.

Reading is a wonderful habit to develop. It is a great thing to do when you are bored. Here are some ways to develop a reading habit.

Start by reading a few minutes every day. Read every day, even if it is just for 10 minutes. Read when you get up early or before you go to bed. If you can, read at the same time every day. This will make your brain regard it as "reading" time.

Read what you are interested in. Reading can be a trouble if you do not like the book. Reading books that you enjoy will help you stick to (坚持) your habit and become a reader. Once you have great interest, it's hard to put a book down.

Carry a book everywhere. Books can be heavy and big, which used to make it hard to read everywhere. Now you can read books on a smartphone. When you are waiting for a bus or waiting in line at a store, open your book app and read. If you cannot read on an app, find a book that is easy to carry with you.

Set a reading goal. A goal is something you are trying to achieve. Maybe your goal will be to read 5 or 10 books this year, or you even try to read 100 books. Setting a goal will remind you to read every day. Reaching it will make you feel good and make reading even more fun.

Look for city tourism cards. With these cards, you can pay less at restaurants and shops. You don't have to wait for a long time at busy attractions. You might even get free tickets to top tourist attractions. City tourism cards can save your money and time without question.

Don't get the best room. How long will you stay in your room? Will you just be sleeping there? Do you really need a bigger room with a good view?

Find a hotel outside a city. It can help you save some money by choosing a hotel away from big tourist attractions, for you are always doing the same—go to the attractions and return to the hotel to sleep.

Book a room with a kitchen. Although some people might not like to cook while on vacation, I don't mind making breakfast in my room. People always eat at a nice restaurant on their last night of the vacation. I'd rather (宁愿) eat breakfast and lunch at the hotel and then spend much money on a delicious supper.

Emma: I was so excited about it for the first two days that I couldn't listen to the teachers carefully. But soon my classmates and I got used to this new classroom arrangement (安排). Now our class is quieter. What's more, we can come up with our own ideas and learn more through discussion. It's a better way to study.

David: I like it, too. Group members first discuss, and then show to the whole class. It encourages us greatly.

Linda, an English teacher: This was part of a reform (改革) at our school. The school made this reform because we want to offer students easier ways to study and more chances to discuss. Our school hopes to improve students' abilities to study by themselves and work in groups.

Steven, the school master: The reform has demanded (要求) more from teachers. Now they have only15 minutes to give a lesson that would have been taught in 40 minutes before. It is difficult to teach in such a short time. The teachers have to find better ways to teach more effectively (有效地). The reform demands more, but I'm sure it is helpful.

As a festival, Qingming is believed to have a history of about 2,500 years. The most important tradition of Qingming is to honor ancestors and remember the dead family members. So Qingming is also called Tomb-Sweeping Day. When sweeping the graves, people pray, clean the tombstones and burn offerings, usually paper money, paper clothes, paper houses and now even a paper phone.

Lots of ancient poets expressed their sad feelings with words. One of the most famous poems describing the festival was the poem Qingming by Du Mu of the Tang Dynasty as follows: A drizzling rain falls like tears on the Mourning Day; The mourner's heart is going to break on his way. "Where can a wine shop be found to drown my sad hours?" A cowherd points to a cot amid apricot flowers.

Some traditions of Qingming have brought such problems as traffic jams and air pollution or even forest fires. As part of a greener Qingming campaign, people have been encouraged to pay respect to their ancestors and dead family members online, or burn less or no paper money to protect the environment.

How is it going? Thank you for sending me a1. I really like the stamp on the postcard. It's2. I like it. Oh, I forgot to say sorry to you. Just now I didn't answer your phone call. Ha ha, when you called me, I was taking a shower in the3.

Now I will tell you Cindy's4. Cindy lives at 16 Park Street. It's very5 to take the subway to Cindy's house. Her house is across from the subway station. Of course, you can drive a car there. Near Cindy's house, there's an underground6. But I7 you to get there by subway. Taking a car can cost lots of money. Taking the subway is inexpensive. On the left of her house, there's a small8. From Monday to Friday, it's9. But on the weekend, you can see many people buy books there. On the right of her house is a fruit store. In it there are all kinds of fruits such as bananas, apples, oranges and10. Before you visit Cindy, you should give her a call. Oh, I have to go! Mom needs my help.

Yours,

Jeff
