For thousands of years, people in different parts of the world have worn very different types of clothing. There are four big reasons for this.
One reason might be religion. In many Moslem countries, women must wear veils (面纱) to hide their faces. The veils must be worn in public. Veils are part of the Moslem religion.
The second reason is that different materials are used in different countries. For instance, in France the materials used in clothing may be cotton, silk, wool, or many other man-made materials. Most people in China wear cotton.
The ways clothes are made are also very different. This is another reason why people dress differently. Western countries rely on machines to make most of their clothing. Someone living in India can use only hand power to make the clothing he needs.
Worldwide differences in customs also lead to differences in clothing. A Mexican farmer wears a straw hat with a brim (帽沿) up. In China, a farmer wears a straw hat with a brim down. Both hats are used to protect the farmers from the sun. Some of these customs have come down through thousands of years.
If you want to learn about the differences about people in the world, you______ .

C.may study the different types of clothing people wear
D.may be surprised by the ways people wear hats

If an Eskimo is【29】lucky, he may kill a whale(鲤鱼),【30】 a dead whale may wash up on the shore near his house. The whale is an especially useful animal, because it gives a great【31】 of oil.

But as early as 1803, an ingenious Maryland farmer, Thomas Moore, had been on the right track. He owned a farm about twenty miles outside the city of Washington, for which the village of Georgetown was the market center. When he used an ice-box of his own design to transport his butter to market, he found that customers would pass up the rapidly melting stuff in the tubs of his competitors to pay a premium price for his butter, still fresh and hard in neat, one-pound bricks. One advantage of his ice-box, Moore explained, was that farmers would no longer have to travel to market at night in order to keep their produce cool.
What is the main idea of this passage?
A.The influence of ice on the diet.
B.The transportation of goods to market.
C.The development of refrigeration.
D.Sources of the term "ice-box".
One story of the discovery of the coffee plant relates to this effect of caffeine. According to the story, coffee was discovered in East Africa. The story says that coffee was first found by a goat farmer named Kaldi. This was about the year 850.
Kaldi was leading his animals through the mountains and the goats were stopping repeatedly to eat the plants near the path. Suddenly, some of the goats started jumping up and down in a very strange way.
Kaldi figured out that the goats were acting this way because of the plants they were eating. Kaldi himself tried eating some of the green beans that the goats had been eating. He, too, felt the stimulating effect of the beans.
Kaldi wanted to prove what had happened, so he picked some of the beans and took them back to his home village, where he told his story. The green bean got the name "Kaffa" and later "coffee" because the beans were discovered in a place called Kaffa in Africa.
Then for years, people used to eat a few of the green Kaffa beans when they were in the mountains and needed extra energy or stimulation. It was later found that the coffee beans could be picked and then dried until they turned brown, and then they could be stored. If the beans were dried and stored, they could be used at any time.
Caffeine is a kind of drug that can______.
A.strengthen one's heart
B.make one's bones strong
C.make one more active or alert
D.ease the pain on the body
Each day every person in the United States throws away more than five pounds of garbage(垃圾). There is more garbage now than ever before and most of it is made up of the packages and cans in which we put our food. The traditional way of getting rid of solid wastes is quickly becoming inadequate. Many cities are experimenting with newer ways of handling their growing piles of garbage.
One of these new ways is "recycling"(回收使用). Through recycling usable materials are taken out of garbage and made into something else. These usable parts of garbage are put through the cycle of going from a raw material to a finished product again.
In some cities a machine called Hydrapulper is being used to help recycle garbage. A Hydrapulper is like a huge mixing machine. The garbage is dropped onto a conveyor belt (传送带) that feeds the machine. At the same time, water is pumped into the Hydrapulper. With a mixing action, the Hydrapulper throws out the heavy metal objects that can later be sold as waste metal. The rest of the garbage—paper, food, plastic, rubber, glass, wood, leaves, and other items—falls apart. The waste is then mixed with water and carried to another piece of equipment where glass, sand and small pieces of metal are thrown out.
With the Hydrapulper, up to 95 percent of the original garbage is made again useful. The rest turns into furnace ash(炉灰).
Traditionally, garbage is thought to be ______.
A.a worthless burden to big cities
B.something that can be reused
C.a raw material for making new products
D.able to be recycled but difficult to handle
