Ten years ago, I began to study luck. I wanted to know why some people are always in the right place at the right time,1 others always experience bad luck. Many people volunteered for my research. Over the years Iinterviewed them, watched their lives and asked them to 2 my experiments(实验).
I did a simple experiment to find out why there were 3 in their ability to catch the chances. I gave both lucky and unlucky people a newspaper and asked them to look through it and tell me how many photos were inside. Ihad 4 placed a large message halfway through the newspaper saying, "Tell the researcher you have seen this and win $50." This message took up half of the page and was more than two inches high. It was staring everyone straight in the face, but unlucky people were likely to 5 it.
Unlucky people are just more 6 than lucky people. They are busy looking only for what they need and this stops them from noticing the 7 things. As a result, they miss out on chances. Lucky people are more relaxed and open. They can see everything that is in front of them, 8 just what they are looking for.

They pull people out of their fantasy(幻想) and 9 them to realize their situation. But should we feel hopeless? Of course not! Just try 10 "luck" in life with your eyes and hearts. In this way, you may get some gifts out of your expectation.

Cotton or plastic, which kind of bag is better for the environment? Many of us would naturally say that the cotton bag is better but that might only be true if you use that bag thousands of times. Surprised?Keep reading.
Producing it can set toxins(毒素) into the air. It's used everywhere but often thrown away after a single use. Thrown-away plastic can lie in the ground for centuries or enter the sea causing harm to wildlife.
As a result, many people are looking for ways to reduce their plastic use. However, it's not easy to achieve it. It's certainly more biodegradable(可生物降解的) than plastic. But the industrial production of cotton requires far more energy. A report from Columbia University shows that cotton shopping bags need to be used over 7,000times before they are more sustainable than plastic ones.
Lightweight plastic parts in cars and planes help reduce fuel use(燃料使用) and emissions. If we didn't use plastic in clothing and footwear, the amount of land, water and chemicals needed to produce enough natural materials would be very large.
Plastic lasts for centuries, but it also means it can be used to make things that can be reused again and again. So if we have to use them, then reuse them more, just for a better environment.
A. Let's return to our cotton bag.
B. Plastic bags are in great need.
C. It's not just about shopping bags.
D. The problem is that we often don't.
E. That means even more than needs to be produced.
F. There is no doubt that plastic is bad for the environment in many ways.

The Great Wall of China is the longest wall in the world. This is due to a thin layer(层) of plant life called biocrust, including moss, lichen and cyanobacteria.
The Great Wall of China was built in sections over a period of around 2,000 years. The first parts were started around 220 BC. But in some areas, it was built using"rammed earth". This is when earth and rocks are pressed together. How have the old sections of the Great Wall managed to survive for such a long time?
A group of researchers examined a 30-mile-long part of the wall. Surprisingly, more than two thirds of it was covered in biocrust. This means that the biocrust has actually strengthened the wall and protected it over the years.
These findings could be important for people who manage ancient buildings around the world. Although biocrust may not look very nice, it has a very special ability. This could be a valuable tool for experts looking for ways to protect valuable ancient buildings.
A. Biocrust can provide a living place for insects.
B. It can help protect things from being harmed by weather.

In recent years, homework has been discussed heatedly. Many parents and educators worry about homework. Research shows that this worry is valid(合理的).
So what does research say? First, research finds homework can bring higher scores. Researchers find that if primary school students do some writing homework every day, they can get better grades in writing. It only happens when students are given the proper amount of homework.
Homework is not simply to improve grades. Research finds that homework has other advantages, such as building independence and developing time management skills. For example, that may cut down on chances of free play, which is important for students' language and social skills. What's worse, students often don't have enough time for physical activities.
As a result, it's necessary to give students the right amount of homework. Research suggests middle school students should do no more than 1 hour's homework. To realize those, teachers had better not assign(布置) too much homework. And parents should help students learn to manage their time, especially for homework.
A. But the good influence isn't always there.
B. But too much homework works oppositely.
C. That's the reason for many students' overweight.
D. So we should pay attention to the value of homework.
E. They question if students should get so much homework.
F. And homework for primary school students should be less.

Usually, they appear to move in the same . If you record their orbits night after night, however, you' ll find that they sometimes seem to go backwards in their paths.

Those closest to the Sun travel faster than those farther out. When a planet its orbit once,a year has passed on that planet. For example, one year is88 Earth days on Mercury and 687 on Mars.

And Earth laps Mars two years. When the Earth and another planet pass each other, an optical illusion(视觉错觉) is created.

Diaojiaolou is a traditional building in China.It's popular among Miao, Zhuang, Buyi and Tujia people. You can find these houses standing beside a river or in the mountainous areas of Yunnan, Guangxi,Hunan and Sichuan. The history of Diaojiaolou dates back to 1,400 years ago.
The traditional building, usually two to three floors high, is a wooden house built on stilts. The high hanging floors of the structure are held up by wooden stilts, which give the house an unsteady(不稳定的) appearance from far places. But a Diaojiaolou is, in fact, strongly fixed because its stilts are further strengthened by stone blocks at their bases. Even if one of the stilts are broken, the building will still have a strong support. The ground floor is used as space for firewood and farming tools. These things stay on the ground floor, while people always live above it.
One of the main advantages of Diaojiaolou is that while in ancient times, these stilted buildings would provide protection from wild animals, nowadays they continue to provide protection from snakes and insects. What's more,these buildings help prevent some illnesses that are common in southern China. The cool wind blowing through the windows of the upper levels behaves like a kind of natural air conditioner(空调), which makes people feel very comfortable.In mountainous areas, people can't stand humidity on the ground during summer, so lifting living spaces and making sure about dry living environment are especially necessary.

What makes us human? Is it our thoughts?Our emotions? Our behavior?
All of these things make us who we are, but at the center of it all lies the genome(基因组)—— the genes inside our bodies that determine everything from our hair color to our intelligence. But if we could change our genome, would we still be human?
Recently, a group of scientists from the United States and South Korea worked together to successfully"edit" a human embryo(胚胎) and remove a genetic mutation(变异) that would have led to heart disease, reported The Guardian.
This was achieved with the help of CRISPR--a gene-editing tool that allows scientists to edit the genome by cutting, changing or adding to parts of it.
Scientists involved in DNA editing are certain about the good of their work, and hope that in the future, diseases or birth defects could simply be"edited out".
However, others aren't so sure. People are worried that the science could be used not only to remove life-threatening illness, but also to make a"perfect" baby whose DNA had been chosen to improve their intelligence or other qualities.It might make having a baby similar to choosing a new house or car. Critics(评论家) say that this is a shallow way of thinking about raising children.
"It makes you think about who we are as people, and it makes you ask if humans should be using the kind of power...that is changing human evolution(进化)," Jennifer Doudna of the University of California, Berkeley told MIT TechnologyReview.
Still, others worry that DNA editing could be turned into an expensive service that would only be available to the people who could afford it. That might mean the rich would be given another advantage in a world where they already have plenty of them.
"You could find wealthy parents buying the latest‘upgrades' for their children, leading to even greater inequality than we already live with," Marcy Darnovsky,director of the San Francisco Center for Genetics, told BBCNews.
(1)、Why are the questions asked in Paragraph 1?A、To attract the readers' interest. B、To seek answers from the readers. C、To show those things aren't important. D、To correct our understanding of human beings.(2)、Which of the following will Jennifer Doudna most probably agree with?A、Having a perfect baby is not so good for the family. B、Life-threatening illnesses should be removed before birth. C、DNA editing might cause unexpected problems to humans. D、DNA editing may enlarge the gap between the rich and the poor.(3)、What does the underlined word"them" most probably refer to?A、Advantages. B、Expensive services. C、Perfect children. D、Qualities.(4)、What does the author think of DNA editing?A、It's good for human evolution. B、It will make humans look similar. C、Its influence is still quite uncertain. D、It can only be afforded by the rich. -

Sometimes having a teenager at home can be a real headache. Many teenagers smoke, drink, wear strange hairdos and even fight. Basically, they are often taking risks.
Earlier studies have shown that teenagers are more likely to make irrational decisions than people from any other age group, including children and adults. Is it that teenagers are too young to tell right from wrong? Not really.So what explains their risky behavior?
According to Laurence Steinberg, a professor at Temple University, the US, the reason is that teens care a lot about how their peers(同龄人) view them—— that's the effect of"peer influence", reported Science Daily. As children enter their teenage years, they spend more time with their friends and classmates and also become more sensitive to their feedback. This sensitivity drives teenagers to concentrate on the short- term benefits of making risky choices and overlook the costs.
In a test, a group of teenagers were asked to play a video driving game. When they played with their friends watching, they took more chances and drove more carelessly because that would increase their possibility of winning. But when they played alone, they tended to drive more safely.
Why does pressure from peers have such a big influence on teens' behavior? As Steinberg sees it, a teenager's brain is like a car with a good accelerator(油门) but a weak brake. The"accelerator", the brain's ability to notice the benefits of things, is fully developed by teenage years while the"brake", the brain part related to controlling impulses(冲动) and long- term thinking, is still immature. When teens are under the pressure of being judged by their peers,they tend to push hard on the accelerator. Given how weak the brake is, it is likely that they are going to end up in a crash.
But the good news here, according to Steinberg, is that a violent teenager doesn't necessarily become a violent adult.About two- thirds to three- quarters of violent youth grow out of it."They get more self- controlled," Steinberg told Live Science.
Also, people who haven't committed a violent crime by age 19 are less likely to start doing it later, added Steinberg.
