题型：不详难度：来源：

Apparently，we are safe neither at home nor in the business office．We use water in both places，but the research shows that chemicals added to our local water supply to kill harmful bacteria can have unwanted side effects．These chemicals can cause potential harm through drinking and in seemingly harmless activities as cleaning one’s house．They are released(set free)from water by daily actions like water running out of tap，spraying from garden pipes，or splashing in dishwashers and washing machines．As the water is moving．these chemicals are released into the air and then breathed in. Once inside our bodies, they start to affect our health.
Does this mean we should stop bathing? No, say the scientists, but we should put all pollution into perspective. Activities at home such as the burning of coal, cooking oil, or even candles release carbon monoxide and particulates such as cigarette ashes which have been proven as harmful to health as working or living near heavy traffic. New tugs, bedding, and even clothing give off that“new smell, ”which is a sure sign of chemicals. In the office, newly applied paint, newly purchased telephones and other telecommunications equipment, and computers release polluting chemicals, too. As offices and homes often have inadequate ventilation (通风), these chemicals can build up to become health problems. Their poisonous effects are only now being slowly recognized.
These facts suggest that, at a minimum, proper airing of newly purchased goods with an obvious chemical smell is a wise warning. Home and office windows should be opened during good weather. Even one’s car needs to be ventilated as well while in the garage.
We need further research to understand better other potential health dangers, too. For example, the effects of overcrowding of schools (carbon dioxide build-up ), the factory work environment ( an endless list of potentially dangerous substances ), and even home heating and cooling (the air conditioner may be our enemies, not our friends) have only recently started to come to light. Until we understand the effects of our new technological environment better, we can only hope that“there is no place like home.”
64．What is the main idea of the first paragraph?
A．The air we breathe in is harmful.
B．The water in everyday use is unsafe.
C．Chemicals are added to the drinking water.
D．Chemicals are released in the running water.
65．In Paragraph 2, the underlined sentence means that .
A．bathing should be done with caution
B．homes and offices should be aired often
C．any pollution should be taken into consideration
D．we should prevent any pollution from doing harm to us
66．What is the purpose of the passage?
A．To call on us to guard our water.
B．To show us that no place is like home.
C．To make us aware of the pollution around us.
D．To argue that neither homes nor offices are safe.

There are thousands of products of all colors and shapes in a supermarket, making you believe that they are worth a try. How? Packaging （包装）is the silent but persuading salesman.
There on the shelves, each bottle, can, box, and jar has been carefully designed and measured to speak to the inner self of the consumer（消费者）, so that is buying not only a product but also his belief in life. Scientists have studied consumer behavior recently and found that the look of the package has a great effect on the “quality” of the product and on how well it sells, because “Consumers generally cannot tell between a product and its package. Many products are packages and many packages are products,” as Louis Cheskin, the first social scientist studying consumers’ feeling for packaging, noticed.
Colors are one of the best tools in packaging. Studies of eye movement have shown that colors draw human attention quickly. Take V8 for example. For many years, the bright red color of tomatoes and carrots on the thin bottle makes you feel that it is very good for your body. And the word “green” today can keep food prices going up.
Shapes are another attraction. Circles often suggest happiness and peacefulness, because these shapes are pleasing to both the eye and the heart. That’s why the round yellow M signs of McDonald’s are inviting to both young and old.
This new consumer response（反应）to the colors and shapes of packages reminds producers and sellers that people buy to satisfy both body and soul.
60．According to the passage, ______ seems to be able to persuade a consumer to buy the product.
A．the pleasing color of the package    B．the special taste of the product
C．the strange shape of the package     D．the belief in the product
61．If a package or a product is round in shape, it can ________.
A．bring excitement to the consumers B．attract the consumers’ attention
C．catch the eye movement of the consumers   D．produce a happy and peaceful feeling
62． “And the word ‘green’ today can keep food prices going up.” This sentence suggests that consumers today are ________.
A．starting to notice the importance of new food
B．enjoying the beauty of nature more than before
C．beginning to like green vegetables
D．paying more attention to their healthy
63．It can be inferred from the passage that V8 is a kind of ________.
A．vegetable dish B．healthy juice    C．iced drink D．red vegetable

LONDON（Reuters）-Organic fruit, delivered right to the doorstep. That is what Gabriel Gold prefers, and he is willing to pay for it. If this is not possible, the 26-year-old computer technician will spend the extra money at the supermarket to buy organic food.
"Organic produce is always better," Gold said. "The food is free of pesticides（农药）, and you are generally supporting family farms instead of large farms. And more often than not it is locally（本地）grown and seasonal, so it is more tasty. "Gold is one of a growing number of shoppers buying into the organic trend, and supermarkets across Britain are counting on more like him as they grow their organic food business. But how many shoppers really know what they are getting, and why are they willing to pay a higher price for organic produce? Market research shows that Gold and others who buy organic food can generally give clear reasons for their preferences-but their knowledge of organic food is far from complete. For example, small amounts of pesticides can be used on organic products. And about three quarters of organic food in Britain is not local but imported（进口）to meet growing demand. "The demand for organic food is increasing by about one third every year, so it is a very fast-growing market," said Sue Flock, a specialist in this line of business.
60. More and more people in Britain are buying organic food because ____.
　　A. they are getting richer
　　B. they can get the food anywhere
　　C. they consider the food free of pollution
　　D. they like home-grown fruit
61.Which of the following statements is true to the facts about most organic produce sold in Britain？
　　A. It grows indoors all year round.
　　B. It is produced outside Britain.
　　C. It is grown on family farms.
　　D. It is produced on large farms.
62.What is the meaning of "the organic trend" as the words are used in the text？
　　A. growing interest in organic food
　　B. better quality of organic food
　　C. rising market for organic food
　　D. higher prices of organic food
63.What is the best title for this news story？
　　A. Organic food-healthy, or just for the wealthy？
　　B. The making of organic food in Britain
　　C. Organic food-to import or not？
D. Good qualities of organic food
