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.”

What is the main idea of the first paragraph?

　　A.The air we breathe in is harmful.

B.Chemicals are released in the running water.

C.Chemicals are added to the drinking water.

　　D. The water in everyday use is unsafe.

.In Paragraph 2, the underlined sentence means that .

　　A. homes and offices should be aired often

　　B. any pollution should be taken into consideration

　　C. bathing should be done with caution

　　D.we should prevent any pollution from doing harm to us

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.

　　What do you know about the sea? You may have seen it. Some of us have swum or bathed in it. It looks beautiful on a fine sunny day and it can be very rough when there is a strong wind. What other things do we know about it? Of course, the sea is very large. In the world there is more sea than land. The sea covers three quarters of the earth. The sea is also very deep in some places. It is not deep everywhere, some parts of it are very great. At one spot, near Japan the sea is nearly 11 kilometres deep! Just think of it, the highest mountain in the world is only about 9 kilometres high! If you have swum in the sea, you know that the water is salty. Rivers carry salt from the land into the sea. Some parts of the sea are more salty than other parts. Do you know the Dead Sea in Arabia? It is very salty. Swimmers cannot sink in it! Fish cannot live in the Dead Sea. It is a strange sea. In most parts of the sea, there are a lot of fishes and plants. Some live near the top of the sea. Others live deep down. No sunlight can reach the depth of the sea. So it is completely dark. Strange fishes live there. Some are blind. Some have their own lights. Some have great jaws. With their great jaws, they swallow fish larger than themselves. The sea can be very cold. Deep sea divers know this well. At the top the water may be warm. They as the divers go down, the sea becomes colder and colder.

　　Many scientists are now making a study of animal and plant life in the sea. They hope to find new resources for mankind.

Now let us look at how we read．When we read a printed text, our eyes move across a page in short, rough movement．We recognize words usually when our eyes are still when they fixate(凝视)．Each time they fixate, we see a group of words．This is known as the recognition span or the visual span．The length of time of which the eyes stop ---the duration of the fixation ----varies considerably from person to person．It also varies within one person according to his purpose in reading and his familiarity with the text．Furthermore, it can be affected by such factors as lighting and tiredness．

Unfortunately, in the past, many reading improvement courses have concentrated too much on how our eyes move across the printed page．As a result of this misleading emphasis on the purely visual aspects of reading, numerous exercises have been devised to train the eyes to see more words at one fixation．For instance, in some exercises, words are flashed on to a screen for, say, a tenth or a twentieth of a second．One of the exercises has required students to fix their eyes on some central point, taking in the words on either side．Such word patterns are often constructed in the shape of rather steep pyramids so the reader takes in more and more words at each successive fixation．All these exercises are very clever, but it’s one thing to improve a person’s ability to see words and quite another thing to improve his ability to read a text efficiently．Reading requires the ability to understand the relationship between words．Consequently, for these reasons, many experts have now begun to question the usefulness of eye training, especially since any approach which trains a person to read isolated words and phrases would seem unlikely to help him in reading a continuous text．

59．The time of the recognition span can be affected by the following facts EXCEPT________ ．

　   A．one’s familiarity with the text   B．one’s purpose in reading

　   C．the length of a group of words D．lighting and tiredness

60．The author may believe that reading ______．

　   A．requires a reader to take in more words at each fixation     

         B．requires a reader to see words more quickly

　   C．demands a deeply-participating mind                      

         D．demands more mind than eyes

61．What does the author mean by saying the underlined sentence in the second paragraph?

　   A．The ability to see words is not needed when an efficient reading is conducted．

　   B．The reading exercises mentioned can’t help to improve both the ability to see and to

comprehend words．

　 C．The reading exercises mentioned can’t help to improve an efficient reading．

　 D．The reading exercises mentioned have done a great job to improve one’s ability to see

words．

62．What is the writer’s attitude in writing this passage?

　   A．critical     B．neutral    C．pessimistic      D．optimistic

　　In the past, Americans used to think of the United States as a“melting pot”of immigrants(移民) from many different cultures to the United States, their old ways melted away and they became part of a completely new culture. The United States was likened to a big pot of soup, which had bits of flavor(味道，滋味) from each different culture. All of the different cultures were so well blended(混合，掺杂) together that it formed its own new flavor.

　　Today, Americans realize that the simple“melting pot”theory is less true. Instead, different groups of people keep many of their old customs. Often groups of Americans from the same culture band together. They live together in distinctive communities, such as“Chinatowns”or“Little Italy”--areas populated almost exclusively(惟一，仅) by Americans of a single ethnic group--which can be found in many large American cities. Living in ethnic neighborhoods gives new Americans the security of sharing a common language and common traditions with people who understand them.

　　In time, however, people from different backgrounds mix together. They also mix with native-born Americans. Old traditions give way to new customs. The children of immigrants are often eager to adopt new, American ways. They often want to dress in American fashions, to speak English and to follow American social customs. By one estimate(估计), about 80 percent of European immigrants marry outside their own ethnic groups by the time they reach the third generation. Third generation means that their great-grandparents were immigrants. Yet as successive generations become more“Americanized”, they often retain significant elements of their ethnic heritage.

1．Ｗhat does the text mainly talk about?

[　　]

A．The American way of life.

B．Immigrants vs．native-born Americans.

C．Old traditions vs．new customs.

D．The multi-cultural heritage of the United States.

2．Why does the author mention“Chinatowns”in the 2nd paragraph?

[　　]

A．To give an example that many people keep their old customs.

B．To show that Chinese cherish their old traditions.

C．To contrast(对比) the Chinese way of life with that of the Italian's.

D．To give an example of the Americanization(美国化).

3．The underlined word“ethnic”in the last sentence most probably means _____.

[　　]

A．moral　　　　B．national

C．cultural　　　D．social

4．The underlined word“Americanized”generally means _____.

[　　]

A．immigrants who still retain their tradition, but behave like Americans in some ways

B．immigrants who still retain their own language, but speak English sometimes

C．immigrants who reject the traditions of their parents, and accept Western culture only

D．immigrants, naturalized by native American culture, in character, way of thinking etc. though still retaining some ethnic heritage
