　　Which animals do we need most? Dogs? Cats? Horses? No! The answer to the question is cows!

　　Why cows? Cows give us milk．And milk is one of our most important foods．Suppose(假设)that all the milk cows make in one year was put into bottles, and suppose these bottles were set side by side, the line of bottles would go all around the world 400 times!

　　That is a lot of milk．Less than half of it is used for drinking and cooking．Most of it is used to make butter, cheese, ice-cream and many other things．

　　It takes many cows to give us that much milk．But not as much as it used to．A cow used to give only about 1, 500 quarts(夸脱)of milk a year．Now a fine cow may give more than 3, 000 quarts in a year!

　　Why do cows give more milk today? Farmers have better cows．The cows get better care and better food．For each two and a half pounds of grass that she eats, a fine cow makes about a pound of milk．But she may not give all the milk she makes．If she is unhappy, she may give only a small part of it．A cow is a friendly animal．If man is kind and speaks softly to her, she gives more milk．She also likes music．

　　Cows give us more than just food．Their skin can be made into shoes．No animal does more for us than cows．

　　When a big ship is in very rough(不平坦的) sea, it has to be able to bend(弯) a little, otherwise it may break in two. If one end of the ship is on the top of one huge wave, and the other end is on the top of another, with the middle of the ship hanging in between; or if one huge wave comes up under the middle of the ship, leaving the two ends hanging, the ship's own weight will break its back if it is quite stiff(硬的).

　　To make a big ship elastic(有弹性的) enough to avoid (避开) this danger, it has joints where the sections of the ship come together above the water-line, and these joints (连接处) open and shut slightly as the waves lift one section(部分) of the ship or another. This is enough to save the ship from breaking into pieces.

　　One day a sailor was walking along a passage-way in a big ship during a storm when he was surprised to see a boy sitting comfortably in a chair at the end of the passage-way, which was opposite one of the ship's joints. The boy had a bag of nuts beside him, and every time the ship was lifted by a wave and the joint opened, he put a nut in it. As the ship came down again, the joint closed and cracked(压碎) the nut, gently but firmly. The boy then took it out and put the next one in as the joint opened again.

2．If one end of the ship is on the top of one huge wave, and the other end is on the top of another, with the middle of the ship hanging in between, what will happen to the ship if it is quite stiff?

3．Why does a big ship have joints?

4．What do these joints do?

5．Where was a sailor walking during the storm in this story?

6．What was he surprised to see?

7．What did the boy have beside him?

8．What did he do?

Americans can travel almost anywhere they choose. But to protect (保护) its people, the government lists a few dangerous places where Americans cannot go. These places are unfriendly countries or countries at war. There, the travelers might not be safe. These countries are listed in a small book called a passport (护照).
This passport is for the safety of its traveling people. It is also a government’s pledge (保证) that the people will follow the rules of the host country. To receive a passport from the government, a traveler must show that he is an American citizen (公民). An American cannot go abroad without a passport. Only the close countries such as Canada and Mexico do not ask for passports. The traveler’s picture is inside the passport. Children traveling with their parents are also in one parent’s book.
