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.
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.
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.

The giant panda only lives in the wild in China. In the early 1980s, were only 1,000 left in the wild. The main reason why pandas are endangered is that the area where pandas can live has become smaller.
The WWF works to help giant pandas in the wild in many ways. One of the ways that helps them is to increase the size of panda reserves(自然保护区). Some reserves need to be joined together by planting bamboo between them to make “corridors”. These are paths that lead from one reserve to another. No one may harm the pandas in these areas. The corridors let pandas move from one habitat (栖息地) to another to look for food. ②People are working very hard to make sure the giant panda does not die out.

I enjoy my stay on your interesting planet(星球).
I think I know the life on Earth now and I would like to tell you my ideas.
First of all you live in boxes. Every morning you leave your boxes and get into smaller boxes on wheels(轮子). All these small boxes run around and around, and finally stop to rest. You leave these boxes on wheels and go to very large tall boxes.
After resting all day, you get back in your little boxes. There you sit and look at very small glowing boxes with moving pictures in them.
There is only one thing I don’t know. Some angry boys fought for a little round (圆的) ball. Everyone shouted(大声喊) but they kept fighting. They were angry, because they had to stay in boxes all day, I think.
Thank you for this chance(机会) to get to know you.
Yours,
The man from Mars(火星)
小题1:How many kinds of “boxes” does the man from Mars tell us?
A.Two | B.Three | C.Four | D.Five |
A.Houses | B.Buildings | C.Cars | D.TVs |
A.发光的 | B.开心的 | C.漂亮的 | D.黑暗的 |
A.To say goodbye to the Earthmen |

A number of students jumped up to thank the teacher and left the classroom. The teacher looked at the rest students and said. “Does anyone else want to get a B? This is your last chance. ”Two more students decided to go. Seven students stayed. The teacher then handed out the papers. There were only three sentences on the paper: Congratulations! You have received an A in this class. Keep believing in yourself.
I never had a teacher who gave a test like that. but I think that it is a test that any teacher could and should give. Students who do not have confidence in what they have learned are B students at most.
The same is true for students in real life. The A students are those who believe in what they are doing because they have learned from both successes and failures. They have learned life’s lessons. whether from school education or from events in their lives,and have become better people. Scientists say that by the age of eight,80% of what we believe about ourselves has already been formed. You are a big kid now and you realize that you have some limits(局限). However,there is nothing you can’t do or leant to be. Sir Edmund Hillary, the first person to reach the top of Mount Qomolangma (珠穆朗玛峰)said,“We do not conquer the mountain, but ourselves. ”
小题1:Some students left the classroom because _________.
A.they were happy with the grade the teacher would give them |

A.they answered all the questions in the exam correctly |
B.they didn’t believe themselves |
C.they believed themselves in what they had learned |
D.they had been working hard for each exam |

A.He wants us to know what our limits are. |

Like people, germs move around the world. They fly with us on planes. When food, clothes, and other things travel around the world, germs travel, too. Some germs are safe, but some are dangerous. Germs cause illnesses like colds and the flu.
Warmer Weather Brings Germs
The world’s weather is changing. Cooler countries are getting warmer, so insects from hot countries can move there. Some of these insects, like mosquitoes, carry dangerous germs. These germs cause headaches, fever, and can even kill people.
Under Your Skin
Your skin protects you from germs. It stops some germs, but not all. They can enter your body when you eat, or when you have a cut. Germs are on your hands, too. They enter your body when you touch your eyes, nose, or mouth.
Fighting Germs
Your immune system(免疫系统) protects you, too. When germs get inside your body, your immune system finds and kills them. Special cells(细胞) move around your body and fight germs. They help you stay healthy. Other cells make antibodies. Antibodies help your body find and stop germs.
What can you do to fight germs? You should wash your hands with soap and water. Soap kills many germs, and water washes them away.
小题1:According to the text, insects ______.
A.kill germs | B.carry germs | C.protect germs | D.love germs |
