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 (遷徙) is probably the migration of fish, which is called “salmon”(蛙魚). This fish is born in fresh(淡的) 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 become too crowded. They move down to the low land. Sometimes they move all the way to the seaside, and many of them are killed when they fall into the sea.
Recently, scientists have studied the migration of a kind of lobster (龍蝦). 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 knows where they go. 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.
【小題1】 Most animals move from one place to another at a certain time to _______.

A.enjoy warmer weather
B.find food more easily
C.find beautiful places
D.get away from crowded places
【小題2】 The underlined word “There” in the second passage means “___________”.
A.in cold waterB.in warm water
C.in salty waterD.in fresh water
【小題3】 Why do the lobsters get into a long line to move?
A.It’s a safe traveling way.
B.The weather is bad.
C.It is still unknown to us.
D.They just don’t want not to be too crowded.
【小題4】 The passage is mainly about ________________.”
A.the migration of animals
B.the migration of fish
C.the travel of animals
D.the secret of nature

科目:初中英語 來源:2012屆重慶萬州巖口復興學校初三下學期第一次月考英語試卷(帶解析) 題型:閱讀理解

Fire can help people in many ways. But it can also be very harmful. Fire can make water hot and house warm, give light and cook food. But fire can burn (燃燒) things, too. It can make trees, houses, animals and other things catch fire (起火). If some people can't run away from fire, it can kill them. This happens in every country every year.
Sometimes big fire can burn forests. A month ago, a large forest fire broke out in Yunnan Province. It lasted nearly half a month. The forest in Heilongjiang Province and the grassland in Inner Mongolia caught fire in May, 2006. After more than ten days' fight, over 30,000 people and soldiers put out (撲滅) the fire at last.
Nobody knows clearly when people began to make fire, but there are many interesting stories about the first time a man or a woman started a fire. One story from Australia tells about a man who went to the sun and brought fire down a long time ago. Today people know how to make a fire with matches (火柴). Children sometimes like to play with them. But matches can be very dangerous. The match can burn a piece of paper and then it can burn a house. A small fire can become a big fire, and destroy many things. Fire kills many people every year. So you must be careful with fire.
【小題1】The main idea of the passage is that _________.

A.fire is dangerous and harmful
B.forest fire can be easily put out
C.who started a fire the first time
D.every month there is a forest fire in Yunnan Province
【小題2】Matches can be dangerous because _________.
A.they always burn a house
B.they can make things catch fire
C.they can burn a piece of paper
D.they kill many animals every year
【小題3】The word “destroy” in the passage means ________in Chinese.
A.破滅B.炸毀C.毀滅D.粉碎
【小題4】The writer of the passage wants to tell us that ________.
A.we know when man began to make a fire
B.people should use fire carefully
C.fire can burn down all things in the world
D.all children like to play with matches

科目:初中英語 來源:2013-2014學年江蘇省無錫市九年級上學期期末考試英語試卷(解析版) 題型:閱讀理解

Astronauts, people who fly into space, need special training. First they go to Houston, Texas. That is the home of the Johnson Space Centre. There they are tested to see how strong and smart they are.

One of the first tests is for the heart. The people walk or run, then the space doctors see how fast their hearts are beating.

Another important test is performed. In this test the person must curl(蜷曲)his body up in a ball. When he is in that position, he is put into a round cloth bag. The doctors give him no idea how long he will have to stay in the bag. If a spaceship broke down in space, the astronauts would get into bags like this. Then they would have to wait and curl up in darkness, until help could arrive. You can see that an astronaut must not be afraid of tight space or darkness.

After the tests, only the best people are chosen to start astronaut training in a training centre. The astronauts in training learn many other things. They learn how to jump out of a moving airplane. They learn to how to blow up a lifeboat and get into it while they are in the ocean. The astronauts also have to learn how to get lifted out of the ocean by helicopter(直升機). That may look fun, but it can be dangerous.

After they finish training, the astronauts continue to work. They stay in good shape by running and doing exercise. They read about their special jobs. In that way they can learn new facts about space travel.

Then the big day comes. The astronaut is told to go to work on a flight into space. The crew members(全體船員)get to know each other first. Then they can learn which job each will do.

1.The astronauts don’t know how long they will stay in the bag in the test because ________________.

A. the doctors need to know how strong they are

B. the astronauts need to show how smart they are

C. good astronauts mustn’t be afraid of darkness or tight space

D. nobody knows when help will come if the spaceship breaks down

2.The astronauts don’t learn how to ________________ in the training centre.

A. walk or run in space                                  B. jump out of the moving plane

C. blow up a lifeboat                             D. get lifted out of water by helicopter

3.Which is the correct order according to the passage?

a. Doctors do tests on the astronauts.

b. The astronauts go to the Space Centre.

c. The astronauts learn new facts about space travel.

d. The best people are chosen for training.

e. The astronauts go to work on a flight into space.

A. a, b, c, d, e              B. d, a, e, b, c              C. b, a, d, c, e              D. c, d, e, b, a

4.Which of the following is NOT true?

A. After the tests, only the best people are chosen to start astronaut training in a training centre.

B. The crew members get to know each other after the tests.

C. One of the first tests is for the heart.

D. An astronaut must not be afraid of tight space or darkness.
