    Scientists are closely concerned with the structure of buildings and with the quality of building materials. The World health Organization (WHO) observes that the introduction of air conditioning and energy conservation (保護(hù)) measures have been accompanied by growing problems of indoor air quality. Some pollutants arise from insulation (隔音) products, some from moving cars, and others from modern housing materials. As many Europeans spend up to 90% of their lives in buildings, the health effects of the indoor climate are very important.

  Some construction materials, including fiberboard, insulation foams and certain glues for man-made wood floor boards, for example, give out organic products such as formaldehyde (甲醛). Heat and humidity increase the release of formaldehyde and the gas seriously harms the eyes. Paint, lacquer, etc. can also release dangerous gas into indoor air.

  Construction materials can cause serious damage, especially when they contain asbestos(石棉). Asbestos is naturally present in rock formations worldwide. It belongs to a family of mineral substances made up of solid, non-combustible(非易燃品) fiber. These properties make asbestos a highly sought-after construction material. As early as 1931, however, public health officers in the United Kingdom revealed the connection between breathing in asbestos dust and such diseases as lung cancer.

  The land on which a building is sited may also contribute to pollution. Some kinds of granite or similar rocks contain traces of radium. As it breaks down, this naturally radioactive element produces some kind of radioactive gas that goes through tiny cracks in walls, floors and building materials, and makes its way into the building and the rooms. The better the homes are insulated, the more is the dangerous gas in indoor air. The main effect of this dangerous gas on health is to increase the risk of lung cancer.

53.What is the main idea of the passage?

       A.Some building materials pollute indoor air.

       B.Some factors cause indoor air pollution.

       C.Asbestos can cause lung cancer.

       D.The land on which houses are built contributes to indoor pollution.

54.Why are Europeans particularly concerned with building materials?

       A.Lots of building materials there are radioactive.

       B.They stay home up to 90% of their lives.

       C.They have a high rate of lung cancer.

       D.They spend most of their time indoors.

55.Why is asbestos a sought-after building material?

       A.It is a kind of insulation foam.

       B.Asbestos will not give out dangerous gas.

       C.This material is not easy to catch fire.

       D.It is rarely present in rock formations.

56.Why should we be careful about the land on which a building is to be sited?

       A.To determine whether the land is firm enough for a building to be sited on.

       B.To make sure that the land contains no radioactive material.

       C.To make certain that the land releases no formaldehyde or other gases.

       D.To check whether it contains any combustible materials.

閱讀下列短文,從每題所給的四個(gè)選項(xiàng)中(A、B、C和 D)中,選出最佳選項(xiàng),并在答題卡上將該項(xiàng)涂黑。

Many Chinese students who have learnt English for more than ten years are still unable to speak English very well when they meet a foreigner. They seem to have mastered the basic language structure (結(jié)構(gòu)), but a conversation in English will make them feel uneasy. They are afraid that other people might find out their mistakes.

    It’s uncommon that many students who are bad speakers of English can write English perfectly. This proves that they are unable to organize their idea in English. The center of the problem is that they lack practice and confidence.

    Why should you be afraid? Do you fear those foreigners with whom you are speaking? Don’t be shy. They will not laugh at you just for a little mistake you make. The best way to get rid of trouble is to learn to speak by speaking more. I am sure that constant practice will help you succeed.

   A. How to Speak to Foreigners            

B. How to Study English Well

   A. they are afraid they can’t understand foreigners

   B. they don’t think their English is poor

   C. they worry about making mistakes in their speaking

   D. they didn’t like speaking to foreigners

   B. If you can write English perfectly, you are able to organize your idea in English.

   C. If you can write good English composition, you can speak English very well.

   D. Many Chinese students can’t speak English fluently because they are afraid of making mistakes.

When several different people look at the same person, it is not unusual for each of them to see different things; when you alone observe one behavior or one person at two different times, you may see different things. The following are but some of the factors that lead to these varying perceptions:

Each person’s perceptions of others are formed by his or her own cultural condition, education, and personal experience.

Sometimes perceptions differ because of what we choose to observe and how we deal with what we’ve observed. It is not necessarily true that person’s perception is based on observations of a particular person. Your observations may be totally controlled by some. Your observations may be totally controlled by what others have told you about this person; or you may focus primarily on the situation or role relationship. Most people do not use the same yardstick to measure their parents, their friends, and strangers.

Sometimes we see only what we want to see ,what may be observed to others because of our own needs, desires, or temporary emotional states. This is a process known as selective perception. Selective perception is obviously more difficult when contradictory information is particularly obvious, but it can be done. We can ignore the stimulus—“He’s basically a good boy, so what I saw was not shoplifting.”  We can reduce the importance of the contradictory information—“All kids get into mischief(頑皮). Taking a book from the bookstore isn’t such a big deal.” We can change the meaning of the contradictory information—“It wasn’t shoplifting because he was going to pay for it later.”...

68.While observing a particular person,        .

A. one is likely to take all aspects into consideration

B .one pays more attention to his or her advantages

C. children often differ from gown-ups in perception

D. one tends to choose certain clues to look for

69. Observation of the same person by two people at the same time may differ because         .

A. their yardsticks are not the same

B. either of them may be slow to catch information

C. the time for observations is not long enough

  D. each of them uses different language to express his or her impressions

70.The underlined word “ignore” in Paragraph 4 means to_____________.

A. understand something              B.try to do something

C. pay no attention to something       D. know something better
