Tears are nature's way of making us feel more comfortable. When our eyes are made uncomfortable by some small pieces of pollution, or when we are cutting onions(洋葱), or when we are exhausted and have "red -eyes" from overwork and late hours, tears form in our eyes to clean and refresh them.
Tears are also a sign of strong emotion. We cry when we are sad and we cry when we are happy.
And tears seem to be uniquely(唯独)human. We know that animals also experience emotions-fear, pleasure, lone-
liness-but they do not shed tears. From this, we can conclude that tears are closely related to the emotional and biological make-up of the human species.
Biologically speaking, tears are actually drops of saline fluid, which is a little bit salty, produced by a gland(腺) in the body. Because salt is an important component, tears may actually constitute the most conclusive evidence that the human animal is the end product of a long evolutionary process that began in the sea.
And it is clear that, in addition to the emotional benefits, the shedding of tears has a specific biological function as well. Through tears, we can eliminate from our body certain chemicals which build up in response to stress and create a chemical imbalance in the body. Crying actually makes us feel better by correcting that imbalance and making us feel good again. And thus the emotional and the biological functions of tears merge(合并) into one and make us even more "human" than we would otherwise be.
Which of the following is NOT a function of tears?
A. Biological. B. Emotional. C. Political. D. Chemical.
Which of the following is the best title of the passage?
A. Tears Are a Sign of Strong Emotion
B. Tears Make Us Feel More Comfortable
C. Tears Are Salty
D. Tears Have a Certain Biological Function

What do you know about the sea? We know that it looks very pretty when the sun is shining on it. We also know that it can be very rough when there is a strong wind. What other things do we know about it?
The first thing to remember is that the sea is very big. When you look at the map of the world you will find there is more water than land. The sea covers three quarters of the world.
The sea is also very deep in some places. It is not deep everywhere. Some parts of the sea are very shallow. But in some places the depth of the sea is very great. There is one spot, near Japan, where the sea is nearly 11 kilometers deep! The highest mountain in the world is about 9 kilometers high. If that mountain were put into the sea at that place, there would he 2 kilometers of water above it ! What a deep place !
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 saltier than other parts. There is one sea, called the Dead Sea, which is very salty. It is so salty that 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 so small that it is hard to see them. Many fish live by eating these.
The sea can be very cold. Divers who go 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 clothes made of metal. But he cannot go very deep. Some people who wanted to go very deep used a very strong diving ship! They went down to the deepest part of the sea in it. They went down to a depth of eleven kilometers !
1.When does the sea look beautiful?
A. When it is calm. B. When the weather is fine.
C. When there is a strong wind. D. When there is a storm.
2. How much of the earth’s surface does land cover?
A. 15%. B. 25%. C. 30%. D. 45%.
3.Why does the writer cite(引用) the sea somewhere near Japan?
A. To show that the sea in some places is very deep.
B. To show that the sea in some places is very shallow.
C. To show that its depth is 9 kilometers greater than the height of the highest mountain.
D. To show that its depth is 11 kilometers greater than the height
of the highest mountain.
4.Which of the following statements about the Dead Sea is NOT true?
A. Swimmers cannot sink. B. It is a safe place for swimmers.
C. It is extremely salty. D. Fish can be found in it.
