When you are near a lake or a river, you feel cool. Why? The sun makes the earth hot, but

it can't make the water very hot. Although the air over the earth becomes hot, the air over the water stays cool. The hot air over the earth rises. Then the cool air over the water moves in and takes the place of the hot air. Then you feel the cool air and the wind, which makes you cool.

Of course, scientists can't answer all of your questions. If we ask, "Why is the ocean full of salty" scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into the cracks. The rain then carries the salt into he earth and into the rivers. The rivers carry the salt into the ocean. But then we ask, "What happens to the salt in the ocean? The ocean doesn't get more slat every year". Scientists are not sure about the answer to this question.

We know a lot about our world. But there are still many answers that we do not have, and we are curious.

The main idea of this passage is ______.

A.people feel cool when they are near a lake or river

B.scientists can explain everything we want to know

C.scientists can explain many things but not everything

D.the salt in the ocean comes from rocks

完成下列各题 A The sea is very big. Look at a map of
the world. There is less land than sea. The sea covers three quarters of the world. The sea is very deep in some places. There is one spot, near Japan, where the sea is nearly 11 kilometres deep. The highest mountain in the world is about 9 kilometres high. If that mountain were put into the sea at that place, there would be 2 kilometres of water above it. If you have swum in the sea, you know that it is salty. You can taste the salt. Rivers,which flow into the sea, carry salt from the land into the sea. Some parts of the sea are less salty than other parts. There is one sea, called the Dead Sea, which is very salty. Because it is very salty, swimmers cannot sink! Fish cannot live in the Dead Sea. In most parts of the sea, there are plenty of fishes and plants. Some live near the top of the sea. Others live deep down. There are also millions of tiny living things that float in the sea. These floating things are very small. It is hard to see them. Many fish live by eating these. The sea can be very cold. Divers, who dive deep down in the sea, know this. On the top the water may be warm. When the diver goes downwards, the sea becomes colder and colder. Another thing happens. When the diver goes deeper, the water above presses down on him. It squeezes him. Then the diver has to wear elopes made of metal. One spot of the sea near Japan is

A.nearly nine kilometres deep

B.almost eleven kilometres high

C.two kilometres above the highest mountain in the world

D.two kilometres deeper than the height of the world's highest mountain

When people want to find out about the weather, they usually go to their radios, TVs, ne
wspapers, or the Internet. However, you can also find many weather signs among wildlife because of their highly developed senses. Drops in air pressure affect small mammals (哺乳动物) and insects in many ways. Try looking in or near the house. Mice are good weather indicators. People who spend a lot of time outdoors have observed that field mice come out of their holes and run around before a storm.

Deer leave the high ground and come down from the mountains before a storm. If you see this, you can be sure that there will be a storm within two days. When you see large numbers of sea crabs on a sandy beach, it is time to leave. A change in air pressure over the water warns the crabs that a storm is coming. To escape the stormy sea pounding the shore, they leave the water and seek shelter on land.

Birds are especially good weather indicators because they also show the effect of a pressure drop in many ways. For example, some birds become easily annoyed and will fight over a piece of bread. Other birds sing just before a storm. It seems they know they won’t get another chance for an hour or two. Birds also seek shelter before a storm. You will sometimes see birds resting in trees or staying closely together on a wire near a building. This is a good storm signal.

Seabirds sit out a storm on land. Anytime you see seagulls sitting on the ground in large groups, reluctant to fly, it is not a very good day to go sailing. It is unusual to see large groups of birds flying overhead in the summertime. Watch for other weather signs if you see this. You should also stay alert if you see migrating birds flying in the wrong direction. These birds may be flying ahead of a storm. And if you can’t see a bird anywhere, look out! They may have flown to a different place because a violent storm is coming in their direction.

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

A.How to pay close attention to important clues in nature.

B.How to become prepared for any kind of weather.

C.How to predict weather changes by wildlife.

D.What to do when we see the weather signs.

2.When a storm is surely coming in two days,().

A.some birds become easily annoyed and fight with each other

B.deer leave the high ground and come down from the mountains

C.large number of sea crabs move on a sandy beach

D.field mice come out of their holes and run around

3.What wildlife indicates particularly well that a storm is coming?

A.Seagulls.

B.Sea crabs.

C.Field mice.

D.Birds.

4.How can you know it’s not a good day to go sailing?

A.Migrating birds are flying in the wrong direction.

B.You can’t see a bird anywhere.

C.Seagulls are sitting on the ground in large groups.

D.Birds are flying overhead in the summertime.

5.What does the want to say?

A.Wildlife is a good helper to predict the weather.

B.Wildlife is more efficient in predicting the weather.

C.People need to find out about the weather change.

D.Get prepared before a violent storm is coming.
