As we know ,the environment around us is getting worse and worse. Some chemical factories always pour waste water into the stream. And they also produce terrible gas. In some places, some people even have no clean water to drink. So I think we must do something to protect the environment.
How to protect the environment? First, as a student, we should use cloth bags instead of plastic bags when we go shopping. Second , we had better reuse the old textbooks as possible as we can. Third, we should never forget to turn off the lights when we leave the classrooms. In a word , we must try our best to protect our environment. I believe we can make the world a better place to live in.

When I was a girl of 10, I joined the school cross-country team and practiced twice a week, on the 1,8-km course I'd never really run before and I thought the course would be easy. It was a real shock I ran out of breathe(´­Æø)within the first few minutes. I never realized how tiring running could be but I didn¡¯t t think about give up.
Over time,I did get a little bit faster. However, I was really slow. In races, I would finish close to last. I'd always have to stop more than once, especially in the longer races, which were 2. 5 to 2. 8 km. After every race, I'd go home and cry. But 1 still didn't stop running, holding onto that picture of crossing the finishingline and finally doing well.  
Then one of my friends joined the team, too. She could run easily and even came in the 18th in a big race! I felt so slow and my confidence(×ÔÐÅ) was lower than ever. I became so nervous when I thought of the races that I wanted to give up badly.
Still. I refund to. Finally. 1 realized that the reason I was to nervous was that I was always worried that I wasn't ready for them. So a few weeks before the next 2. 8-km race. I practiced running almost 3 km every day. which helped me improve my pace(²½·¥).
When the time came for the big race, all that practicing really paid off. I stopped only once and my pace was so much better.
I realized that I¡¯d finally gotten happiness with running. But the funny thing was. It didn't come from doing better, Instead, it came from the fact that I hid tried harder and never given up.

C£®practiced running every day D£®never thought running so tired
СÌâ2:The writer was nervous about the race because she_______.

A£®brought good results B£®coat a lot C£®saved much time D£®came to fail
СÌâ4:It can be inferred(ÍƶÏ) from the passage that the writer______.
A£®got angry with her friendB£®wasn't pleased with herself
C£®was a person with a strong mind D£®had no Interest In running

Do you know why you sleep? You may think it¡¯s because you¡¯re tired. Or perhaps you¡¯ve been told sleep is good for you. Yet no one knows exactly why or how people sleep.
Until the early 1950s, most scientists thought the body and brain rested during sleep. Then a scientist watched people sleep. He noticed that during periods of between 5 and 30 minutes each, sleepers¡¯ eyes made rapid movements, as if they were watching something. He called these periods REM sleep, for Rapid Eye Movement. Periods when sleepers¡¯ eyes did not move he called non-REM sleep.
Whenever the scientist woke people during REM sleep, they were having vivid dreams. Measurements showed that sleepers¡¯ pulses£¨Âö²«£©went up quickly during REM sleep. Their breathing, heartbeat, and the blood going to the brain also increased. Far from being a time of rest, REM sleep is a time when the body is hard at work. Scientists still don¡¯t know the reason for this. Some believe REM sleep makes learning easier. Babies spend a lot of time in REM sleep. Because of this, some scientists believe that REM sleep helps the brain grow. Others think REM sleep is a time for the brain to empty the day¡¯s garbage.
One thing all the scientists agree on is that sleep is necessary. Without enough sleep, people make mistakes. Most major car accidents happen during the early morning hours, when people are sleepiest.
СÌâ1:During REM sleep, a person¡¯s breathing and heartbeat ________.
A£®stopB£®increaseC£®decreaseD£®stay the same
СÌâ2:Which word in paragraph£¨¶ÎÂ䣩3 means ¡°colorful and lively¡±?
A£®easierB£®emptyC£®vividD£®quickly
СÌâ3:Which paragraph tells what happens when people don¡¯t get enough sleep?
A£®1B£®2C£®3D£®4
СÌâ4:What is the main idea of the article?
A£®REM sleep helps the brain grow.
B£®REM sleep has been watched and recorded by scientists.
C£®REM sleep is a time to empty the day¡¯s garbage.
D£®REM sleep is an active time when the body is hard at work.
СÌâ5:You can decide from the article that REM sleep ________.
A£®has a restful effect on people
B£®can be avoided with lots of sleep
C£®is something that all people experience
D£®is something that all scientists agree on
