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 them.
The sea can be very cold. Divers, who dive deep down in the sea, know this. On the top thewater 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. 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
Which of the following is NOT true？A.Fish cannot live in the salty sea
B.The sea gets its salt from rivers
C.Different parts of the sea have different amount of salt
D.There is no fish in the Dead Sea
Fish in the sea live____.A.near the top of the sea
B.deep down in the sea
C.at different depth of the sea
D.on tiny living things in the sea
The deeper divers goes down in the sea,____.A.the warmer the sea becomes
B.the colder they find the sea is

D.the heavier their clothes must be

第5题
But the power of waves striking the shore can still be very great. During a winter gale(大风), waves sometimes strike the shore with the force of 6,000 pounds for each square foot. That means a wave, 25 feet high and 500 feet along its face, may strike the shore with a force of 75 million pounds.
Yet the waves, no matter how big or how violent, affect only the surface of the sea. During the most violent storms, the water a hundred fathoms(600 feet) beneath the surface is just as calm as on a day without a breath of wind.
According to the passage, destruction caused by high waves occurs ______.
A．regularly
B．rarely
C．frequently
D．suddenly

Task 2
Directions: This task is the same as Task 1. The 5 questions or unfinished statements are numbered 41 through 45.
Very high waves are destructive when they strike the land. Fortunately, this seldom happens. One reason is that out at sea, waves moving in one direction almost always run into waves moving in a different direction. The two sets of waves tend to cancel each other out. Another reason is that water is shallower near the shore. As a wave gets closer to land, the shallow bottom helps reduce its strength.

For thousands of years we Chinese have always regarded chopsticks the simplest possible and the most efficient tool for transporting bite-sized morsels of food form. a bowl to the mouth. As early as in the Zhou Dynasty， chopsticks were used for picking up meat and vegetables， while hands were used for rice.// Chopsticks， which are roughly uniform. in size throughout China， can be made of a variety of materials， including bamboo， wood， lacquer， jade， ivory， plastic， aluminum， silver and gold. Special long bamboo chopsticks are generally used in the kitchen.// The way we Chinese handle our chopsticks is quite artistic and varied from person to person like one's signature. An average Chinese can very easily pick up a single tiny grain of rice， or a tiny piece of peas， or a slippery button mushroom or sea cucumber.// When using chopsticks， one should place both sticks between the thumb and forefinger. The point is to keep one stick still and move the other so as to make them work like pincers.
