题目列表(包括答案和解析)

We know that many animals do not stay in one place. Birds,fish and other animals move from one place  to another at a certain time. They move for different reasons: most of them move to find food more easily,but others move to get away from places that are too crowded.

When cold weather comes,many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration(迁移)is probably the migration of the fish which is called “salmon”.This fish is born in fresh water but it travels many miles to salt water.There it spends its life. When it is old,it returns to its birthplace in fresh water. Then it gives birth and dies. In northern Europe, there is a kind of mouse. They leave their mountain homes when they bccome too crowded. They move down to the low land. Sometimes they move all the way the seadide,and many of them are killed when they fall into the sea.[来源:Zxxk.Com]

Recently, scientists have studied the migration of kind of lobster(龙虾).Every year, when the season of the bad weather arrives, the lobsters get into a long line and start to walk across the floor of the ocean. Nobody knows why they do this, and nobody know where they go.[来源:Z。xx。k.Com]

So,sometimes we know why humans and animals move from one place to another,but at other times we don’t. Maybe living things just like to travel.

A student newspaper reports that most students go to sleep at 1:30 am. Even if that’s an overstatement (夸张), it’s close to the truth. Scientists say teens should sleep nine hours each night. But that’s hard. Some are even “pulling all-nighters” (开夜车). These students must hand in their homework the next day but they haven’t done it. In the morning they don’t look healthy and you can tell who’s been doing it. One of my classmates did a survey on the topic. She found that most kids pull all-nighters to finish homework, but some do it for other reasons, such as playing computer games!

    Maybe our lack(缺乏) of sleep is because of laziness — I think I’m a rather lazy student — or maybe it’s because we have too much to do in American high schools. I usually go to bed around midnight. If I stayed up past 1:30 am, I wouldn’t get any work done. I’d be falling asleep at my computer. My classes begin at 7:30 am. I’m partly awake in my first class. By the second, I’m a little sleepy. By my third class, I’m sleepy. By midday I’m finally fully awake. But by 3:00 pm, I’m slowing down again. Yet I get more sleep than usual students.

    Most American high schools seem to have a similar(相似的) problem with sleepy students. High school classes start at 7:30 am, so students have to get up one and a half hours before that to get ready and catch the bus. It’s believed that lack of sleep can be bad for both grades and health. Some schools are paying attention. Classes in those schools start at 8:30 am.

1.What does the underlined sentence “it’s close to the truth” mean?

A. It doesn’t tell the truth.         B. It is quite true.

C. It is impossible.              D. I don’t think it’s right.

2.Why do most of the teens have to stay up late?

A. They play computer games.             B. They watch videos late.

C. They have to do a lot of housework.      D. They have to do a lot of homework.

3.When do students in most American high schools have to get up?

A. At 7:30 am.     B. At 6:00 am.    C. At 9:00 am.    D. At about 7:00 am.

4.Which of the following is TRUE according to the reading?

A. The writer usually stays up past 1:30 am.

B. The writer usually goes to bed around midnight.

C. The writer usually does a survey.

D. Many American students don’t get enough sleep, so they can have high grades.

5.What’s the main idea of the passage?

A. Something has to be done to solve the problem of students’ lack of sleep.

B. Many American high school students are sleepy in class.

C. Many kids have too much homework to do.

D. Students can’t play computer games.
