Good tool design is important in the prevention of overuse injuries. Well-designed tools and equipment will require less force to operate them and prevent awkward（别扭的）hand positions. They will allow the worker to keep the elbows（肘）next to the body to prevent damage to the shoulder and arm.
Overuse injuries can therefore be prevented or reduced if the employer provides, and workers use:
●power tools rather than having to use muscle（肌肉）power
●tools with specially designed handles that allow the wrist（手腕）to keep straight （See figure 1）. This means that hands and wrists are kept in the same position as they would be if they were hanging relaxed at a person’s side
 |
Figure1. Bend the tool, not the wrist
●tools with handles that can be held comfortably by the whole hand. This means having a selection of sizes—remember that tools that provide a comfortable firm Hold for a person with a very large hand may be awkward for someone with a very small hand. This is a particularly important consideration for women who may use tools originally designed for men.
●tools that do not press fingers (or flesh) between the handles, and whose handles do not have sharp edges or a small surface area.

This year some twenty-three hundred teen-agers (young people aged from 13-19)from all over the world will spend about ten months in U. S. homes. They will attend U. S. schools, meet U. S. teen-agers, and form impressions of the real America. At the same time, about thirteen hundred American teen-agers will go to other countries to learn new languages and gain a new understanding of the rest of the world.
Here is a two-way student exchange in action. Fred, nineteen, spent last year in Germany with George's family. In turn, George's son Mike spent a year in Fred's home in America.
Fred, a lively young man, knew little German when he arrived, but after two months' study, the language began to come to him. School was completely different from what he had expected --much harder. Students rose respectfully when the teacher entered the room. They took fourteen subjects instead of the six that are usual in the United States. There were almost no outside activities.
Family life, too, was different. The father's word was law, and all activities were around the family rather than the individual(个人). Fred found the food too simple at first. Also, he missed having a car.
"Back home, you pick up some friends in a car and go out and have a good time. In Germany, you walk, but you soon learn to like it."
At the same time, in America, Mike, a friendly German boy, was also forming his idea. "I suppose I should criticize American schools", he says. "It is far too easy by our level. But I have to say that I like it very much. In Germany we do nothing but study. Here we take part in many outside activities. I think that maybe your schools are better in training for citizens(公民). There ought to be some middle ground between the two. " This year _____ teen-agers will take part in the exchange programme between America and other countries.

Today anyone will accept money in exchange for goods and services. People use money to buy food, furniture, books, bicycles and hundreds of other things we need or want. When they work, they usually get paid in money.
Lots of the money today is made of paper. But people used to use all kinds of things as money. One of the first kinds of money was shells. Shells were not the only things used as money.
In China, cloth and knives were used. In the Philippine Islands, rice was used as money for a long time. Some Africans once used elephant tusks, monkey tails, and salt as money.
The first metal coins were made in China. They were round and had a square hole in the center. Different countries have used different metals and designs for their money. Later, countries began to make coins of gold and silver.
But even gold and silver were inconvenient if you had to buy something expensive. Again the Chinese thought of a way to improve money. They began to use paper money. The first paper money looked more like a note from one person to another than the paper money used today.

“Mobile phone killed my man,” screamed one headline last year. Also came claims that an unpublished study had found that mobile phones could cause memory loss. And a British newspaper devoted its front page to a picture supposedly showing how mobile phones could heat the brain.
F
or anyone who uses a mobile phone, these are worrying times. But speak to the scientists whose work is the focus of these scares and you hear a different story.
One of the oddest effects comes from the now famous “memory loss” s
tudy. Alan Preece and his colleagues at the University of Bristol placed a device that imitated the microwave radiation of mobile phones to the left ear of volunteers. The volunteers were good at recalling words and pictures they had been shown on a computer screen. Preece says he still can’t comment on the effects of using a mobile phone for years on end. But he rules out the suggestion that mobile phones have an immediate effect on our cognitive（认识的）abilities. “I’m pretty sure there is no effect on short-term memory,” he says.
Another expert, Tattersall, remarked that his latest findings have removed fears about memory loss. One result, for instance, suggests that nerve cell synapses（神经元突触） exposed to microwaves become more — rather than less — receptive to undergoing changes linked to memory formation.
An even happier outcome would be that microwaves turned out to be good for you. It sounds crazy, but a couple of years ago a
team led by William Adey at the Veterans Affairs Medical Center in California found that mice exposed to microwaves for two hours a day were less likely to develop brain tumours when given a cancer-causing chemical.
“If it doesn’t certainly cause cancer in animals and cells, then it probably isn’t going to cause cancer in humans,” says William. And while there’s still no absolute evidence that mobile phone use does damage your memories or give you cancer, the conclusion is: don’t be afraid. Mobile phone users are worried because ______.
| A．they are not sure whether mobile phones can cause memory loss |
| B．it’s said that mobile phones have a lot of side effects |
| C．one headline reported “Mobile phone killed my man” |
D．a British newspaper s howed mobile phones could heat the brain |

| A．the mobile phone is a most wonderful invention |
| B．there’s no need to worry about the radiation from mobile phones |
| C．something must be done to stop people using mobile phones |
| D．mobile phone companies shouldn’t cheat customers |
What would be the best title for this passage? ______.
| A．New Mobile Phones. | B．Special Mobile Phones. |
| C．New Special Investigation: Mobile Phones. | D．New Investigation. |
Australia －a huge island continent that lies to the south of Asia. Australia－more than two hundred years old, a nation that is still growing.
Its big cities lie on the southeast coast, this is where most Australians live. Australians prefer to own their own houses, though some live in apartments. Australians are a suburban（郊区的） people. The suburbs surround the cities for many miles, and so efficient transport is of great importance. As the economy grows, so do its industries- a higher level of production, a wider range of products.
The Australian works hard, but he likes his leisure. The climate makes outdoor activities the most popular.
Canberra, the capital of Australia, is a planned modern city located inland. Australia is governed by a parliamentary democracy(议会民主). The representatives of other countries have their embassies here. Australia wants to strengthen relations with her neighbors.
Australia is a strange land
, a land of vast expanses- fertile valleys, snow fields and deserts- also a land with unique animal, many that can not be found on any other continent in the world today.
Much of the continent is dry, but man has utilized the land, made it productive, with its tools, with its technology. This is the driest continent of all, and water is a precious possession, more precious than all other natural resources. Large dams are built to collect the water, there to irrigate the fields of pastures（牧场） and crops.
But Australia is changing. The land of wool and wheat is now 
a land of large-scale industry and mining. The costs of developing the new mineral discoveries are enormous, but the rewards are great too.
Australia — a young and developing nation. Australia — a nation that wants to communicate with its neighbors. Australia is an island located ______ of Asia and its big cities lie ____ of the coast.
| A．to the south; on the southeast | B．to the north; on the southwest |
| C．to the east; on the northeast | D．to the east; on the southwest |

| A．dull and wet | B．fine and shiny | C．gloomy and rainy | D．wet and cold |
____ is the most precious source in Australia.
| A．Mineral resource | B．Animal | C．Desert | D．Water |

Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells go
od or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.
Although there are many different types of food, some animals spend their lives eating only one type. The giant panda eats only one particular type of bamboo. Other animals eat only one type of food even when given the choice. A kind of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet. The bear eats fruits and fish. The fox eats small animals, birds 
and fruits. The diet of these animals will be different depending on the season.
Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life. We can infer from the text that humans and animals _________.
| A．depend on one sense in choosing food | B． are not satisfied with their food |
| C．choose food in similar ways | D．eat entirely different food |
Which of the following eats only one type of food?
| A．The white butterfly. | B．The small bird. |
| C．The bear. | D．The fox. |
Certain animals change their choice of food when ___________.
| A．the season changes | B．the food color changes |
| C．they move to different places | D．they are attracted by different smells |
We can learn from the last paragraph that __________.
| A．food is chosen for a good reason | B．French and British food is good |
| C．some people have few choices of food | D．some people care little about healthy diet |
