Have you ever asked 1. (you) why children go to school? You will probably say that they go to learn languages, arithmetic, history, science and some other 2. (subject). That is quite accurate. But why do they learn these things?

We send our children to school 3. (prepare) them for the time when they will be big and will have to work for themselves. Nearly everything they study at school has some 4. (practice) use in their life. But is that the only reason for 5. they go to school?

There is more in education than just 6. (learn) factors. We go to school to learn how to learn, so that when we have left school, we can continue to learn. A man who really 7. (know) how to learn will always be successful, because when he has to do something new, he will not only be able to do it well himself, 8. be able to teach others how to do it in the best way. The uneducated person, on the other hand, is either unable to do something new, or just does it 9. (bad). The purpose of schools, therefore, is not to teach languages, arithmetic, history science, etc., but to teach pupils 10. way to learn.

    Self-esteem (自尊) is all about how much we feel valued, loved, accepted and thought well of by others and how much we value, love and accept ourselves. 1. They tend to have better relationships with others, feel happier, find it easier to deal with mistakes and failures, and more likely to stick to something until they succeed. People with low self-esteem often feel as if no one will like them or accept them or that they don’t do well in anything. The following ways may help you improve your self-esteem.

2. If you’re used to focusing on your shortcomings, start thinking about positive aspects of yourself that overweigh them.

It is good to aim high, but your goals for yourself should be within reach. 3. Mistakes are part of learning, so view mistakes as learning opportunities. Accept that you make mistakes because everyone does.

4. If you realize that you’re unhappy with something about yourself that you can change, start today. If it’s something you can’t change (like your height), start to work toward loving yourself the way you are.

    The results from the world’s largest sleep study have shown that people who sleep on average between 7 to 8 hours per night perform better cognitively (认知地) than those who sleep less or more than this amount.

The world’s largest sleep study was launched in June 2018 and within days more than 40,000 people from the world participated in the online scientific investigation, which included an in-depth questionnaire and a series of cognitive performance activities.

“We really wanted to capture the sleeping habits of people around the entire globe. Obviously, there have been many smaller sleep studies of people in laboratories but we wanted to find out what sleep is like in the real world,” says Adrian Owen, western’s researcher in Cognitive Neuroscience and Imaging. “People who logged in gave us a lot of information about themselves. We had a fairly extensive questionnaire and they told us things like which medications they were on, where they were in the world and what kind of education they’d received because these are all factors that might have contributed to some of the results.”

More than half of all participants reported typically sleeping less than 6.3 hours per night, about an hour less than the study’s recommended amount. One shocking truth was that most participants who slept four hours or less performed as if they were almost nine years older.

Another surprising discovery was that sleep affected all adults equally. The amount of sleep associated with highly functional cognitive behavior was the same for everyone, regardless of age. Also, the harm associated with too little, or too much sleep did not depend on the age of the participants.

“We found that the best amount of sleep to keep your brain performing its best is 7 to 8 hours every night. We also found that people that slept more than that amount were equally harmed as those who slept too little,” says Conor Wild, Owen Lab Research Associate and the study’s lead author.

1.Where did the study take place?

A. In a lab. B. In the street.

C. On TV. D. On the Internet.

2.What may affect the result of the study according to Owen?

A. Career. B. Diet.

C. Education. D. Exercise.

3.What’s Wild’s view?

A. Sleeping too much is as bad as sleeping too little.

B. People must sleep for eight hours every night.

C. Sleeping too little can make people look older.

D. People needn’t pay attention to the amount of sleep.

4.What can we learn from the text?

A. Owen and Wild are the first to study sleep.

B. Lack of enough sleep is a common problem.

C. All the people in the world show interest in the study.

D. There is no effective way to solve the sleep problem.

    About 150 million years ago, in Montana, a young dinosaur roamed through a land. Not yet five years old, the long-necked creature somehow ended up buried in a violent and muddy flood, forever freezing it in adolescence.

Now, researchers have found this potentially record-setting dinosaur. After uncovering the remains, the scientists argue that the skull (烦骨) is the smallest yet found from a group of long-necked dinosaurs called Diplodocus (梁龙). The little fellow even has a nickname ： Andrew, after Andrew Carnegie, who funded the research, and there is a Diplodocus species named after him.

With its skull just 10 inches across , researchers’ best guess is that Andrew was a juvenile Diplodocus—an especially rare find. While more than a hundred Diplodocus samples have been discovered, their skulls are much rarer. Fewer than a dozen have been dug up to date. If the researchers’ reconstruction is correct, Andrew’s skull could be the smallest and least mature Diplodocus skull ever found, potentially providing insights into the dinosaur’s development.

Kristi Curry Rogers, a paleontologist at Macalester College in Minnesota doesn’t fully agree with the findings because of the poor preservation of the fossil (化石). Andrew’s skull is missing parts of the cheek, palate and lower jaw, plus the fossils are slightly pressed. These problems make it hard to reconstruct the skull, let alone infer the dinosaur’s behavior from it.

“The researchers don’t address the damage of the skull or the missing components of the face in any great detail, which could easily change the explanations,” she said in an email.

For now, Diplodocus is the best guess for Andrew’s identity, but it could also be an unknown species. To help settle the debate, Andrew’s skull is currently being 3-D scanned for future research.

1.What did the researchers discover?

A. The youngest Diplodocus. B. The biggest dinosaur skull.

C. A rare dinosaur fossil. D. A species of Diplodocuses.

2.The underlined word “juvenile” in paragraph 3 is closest in meaning to “_________”.

A. young B. strong

C. ancient D. dead

3.Why does Rogers disagree with the researchers’ guess?

A. The researchers have lost some parts of the fossil.

B. The guess of the fossil lacks enough evidence.

C. She couldn’t understand the researchers’ explanations.

D. She has his own opinions about the dinosaur’s development.
