March 16th is World Sleep Day. This year...

March 16th is World Sleep Day. This year’s slogan (标语) is “Breathe Easily, Sleep Well”. Its aim is to celebrate the benefits of good and healthy sleep.

Sleep is like food for the brain. Enough sleep helps the body and brain grow and develop. According to the National Sleep Foundation in the US, adults need seven to nine hours of sleep every night. For students aged 10 to 17, a healthy amount is about eight to nine hours per night.

But many students don’t get enough sleep because of early school start time and heavy homework. About 80 percent of middle school students don’t get enough sleep, the China Youth and Children Research Center reported. For some students, they want to sleep early, but they keep worrying about their schoolwork and can’t fall asleep quickly. For others, they may even have insomnia which might keep them awake (醒着的)all night.

These sleeping problems greatly affect people’s lives. Experts have shown that lack of sleep for teenagers leads to poor grades. Students without enough sleep cannot pay attention in class or do well in sports. Also, the lack of sleep may make them depressed (沮丧的).

Luckily, with good sleeping habits, it is easier to fall asleep. Some of these good habits include avoiding drinks that make people excited late in the day, going to sleep at the same time each night, and sleeping in a comfortable place that is dark, quiet, and neither too warm nor too cold.

1.If Li Hong is 15years old, how much sleep does she need every night?

A. 10-12 hours.    B. 8-9 hours.

C. 7 hours.    D. Less than 7 hours.

2.What might happen if teenagers don’t get enough sleep?

A. They might do well in sports.

B. Their bodies and brains might grow better.

C. They might feel depressed.

D. They might not be able to finish their schoolwork.

3.The underlined word “insomnia” means “_______” in Chinese.

C. 多动症    D. 失眠症

4.Which of the following are good sleeping habits?

What is language for? Some people seem to think it's for practicing grammar rules and earning lists of words—the longer the list, the better. That's wrong.Language is for the exchange(交流)of ideas and information.It's meaningless knowing all about a language if you can't use it freely. Many students I have met know hundreds of grammar rules, but they can't speak correctly or fluently(流利地).They are afraid of making mistakes.One shouldn't be afraid of making mistakes when speaking a foreign language. Native speakers make mistakes and break rules, too.Bernard saw once wrote, "Foreigners often speak English too correctly."But the mistakes that native speakers make are different from those that Chinese students make. They're English mistakes in the English language.And if enough native speakers break a rule, it is no longer a rule. What used to be wrong becomes right.People not only make history, they make language.But a people can only make its own language.It can't make another people's language. So Chinese students of English should pay attention to grammar, but they shouldn't overdo(做过头)it. They should put communication first.

Last year, my family moved to a new city and I went to study in a place where I had no idea about anything. As time was passed, however, I made some friends who were the coolest in whole world. They were so amazed that I couldn’t imagine life at school without her. I never thought of have a so-called best friend, but later I meet one. She is the kindest girl I have ever known. She never believes all the bad things other tell her about me. Wherever I am down, she does many funny things to make me happiness. Anytime we mess up but fight, we always get together again soon.
