     In almost every big university in the United States football is a favorite sport. American football is not
like soccer.
     Players sometimes kick the ball, but they also throw the ball and run with it. They try to take it to the
other end of the field. They have four chances to move the ball ten yards. They can carry it or throw it. If
they move it to the end of the field, they receive six points. This is called a touchdown. It is difficult to
move the ball. Eleven men on the team try to stop the man who has the ball. If the man does not move the
ball ten yards, his team kicks the ball to the other team.

阅读理解。     Bats are the only "flying animals" in the world. They can"t see very well. We often hear "as blind as
a bat". Yet they have no trouble flying on the darkest nights and finding their ways round. How can
bats fly and see at night? They fly by radar(雷达).
     The bat"s radar system(系统) works the same way as the radar in ships and planes. As a bat flies
through the air, it makes a sound. If the sound hits things, it will come back and the bat"s ears will
receive the message. In this way the bat is able to know where the things are.
     Bats go out for food at night. In the daytime they hang in some dark places. Some people think
bats are bad animals. In fact they are useful animals.

1. We call bats "flying animals" because __________ .A. they have the radar system

阅读理解     Do you know why different animals or pests(昆虫) have their colors? They have the colors mainly to protect
themselves.
     Some birds like eating locusts（蝗虫）,but birds cannot easily catch them. Why? It is because locusts change
their colors together with the change of the colors of crops(庄稼).When crops are green, locusts look green. But
as the harvest（收获）time comes, locusts change to the same brown color as crops have.Some pests with different
colors from plants are usually in danger because others can easily find and eat them.So they have to hide themselves
for lives and appear only at night.
     (18)If you study the animal life,you"ll find that the main use of colors for animals and pests is to protect themselves.
Bears, lions and other animals move quietly through forests. Hunters cannot easily find them because they have the
colors much like the trees.
     Do you ever find an even more strange act? (19)A kind of fish in the sea can send out a kind of very black liquid
(液体) when they are in danger. While the liquid spreads over(散开),their enemies(敌人)cannot find them. And they
can swim away easily.任务一：根据短文内容回答问题。1. How can pests with different colors from plants protect themselves?
    __________________________________________________
