Reading ComprehensionThere are 4 reading passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C), and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the centre.Questions 1 to 5 are based on the following passage:Do parents owe their children something? Yes, they owe them a great deal.One of their chief obligations is to give their children a sense of personal worth, for self-esteem is the basis of good mental health. A youngster(青少年)who is constantly made to feel stupid and unworthy, constantly compared to brighter brothers, sisters, or cousins, will become ,so unsure that he (or she) won't try at all. Of course, they should be corrected when they do wrong; this is the way children learn. But the criticisms should be balanced with praises, perhaps with a smile and a kiss. No child is ever too old to be hugged (拥抱).Parents owe their children firm guidance and consistent discipline. It is frightening for a youngster to feel that he is in charge of himself; it's like being in a car without brakes(制动器、刹车). The parent who says" no" when other parents say "yes" sends a double message. He is also saying: "1 love you, and I am ready to risk your anger, because I don' t want you to get into trouble."Parents owe their children a comfortable feeling about their body, and enough information about sex to balance the misinformation that they will surely receive from their friends. Parents owe their children a set of solid values around which to build their lives. This means teaching them to respect the rights and opinions of others; it means being respectful to elders, to teachers, and to the law. The best way to teach such values is by example. A child who is lied to will lie. A child who sees his parents steal tools from the factory will think that it is all right to steal.l. If parents want a child to grow up well, they should __________.A. tell the child that other children are doing much Better than him/her.B. remind the child that he/she is not bright.C. tell the child he/she is just a grass that people won' t notice.D. help the child to build up self-confidence.2. Why is it frightening for a youngster to feel that he is in charge of himself? Because ______.A. he will drive a car without brakes.B. he is now without needed guidance and discipline.C. he may hurt other people while driving.D. he will take charge of his parents.3. What is the "double message" a parent sends to his children when he says "no" ?A. Other parents say “yes” and I say “no”.B. I love you, but you have to obey me.C. I don't care what other parents say: in my house this will not do.D. I love you, but I have to let you know what is good for you.4. What, according to the author, do parents NOT owe their children?A. Teaching them to have self-respect.B. Making them feel comfortable about their body.C. Giving them a good college education.D. Telling them "no" when necessary.5. What should parents do to help build a sound value system in their children? They should ____.A. tell their children to have a comfortable feeling about their body.B. tell their children something about sex rather than say nothing about it.C. set good examples for their children.D. give their children lessons on a whole set of values.Questions 6 to 10 are based on the following passage:How cold is cold? It all depends on who is talking. To us ordinary people nothing in the world my be so mid as falling through the ice on a frozen lade, or huddling (卷缩)on a windswept mountain hoping to be rescued in the dead of winter. Some may even think they are freezing to death when rushing under an ice-cold shower just out of a warm bed. Indeed, we all know what cold means. Arctic(北极) explorers would laugh at such ideas. Down in the Antarctic(南极), where scientists of many nations spend very dark months living on a sheet of ice two miles thick, the temperature spends most of its time at 50 or 60 degrees Fahrenheit below zero, often with hundred-mile winds and heavy snowstorms. This is the cold that is cold, to them.Space people have still another still another standard. The coldest place in which a person can live and survive is some 400 degrees hotter than space itself. However, the coldest place in earth-colder even than space is inside a machine called a cryostat(低温保持器). Here, scientists and engineers in thousands of laboratories and factories in many parts of the world regularly make cold that turns the South Pole's worst into a pleasant summer day. They are inching toward such cold that there is no temperature at all-down a frozen valley that leads to Absolute Zero, 459.67 degrees Fahrenheit below our zero of a cold winter‟s day.6. According to the passage, nothing is so cold to an ordinary person as ____________.A. waiting for death on top of a mountain in winter.B. being trapped in a mountain swept by wind in severe winterC. taking a cold shower right out of bed.D. slipping on a frozen lake.7. Which of the following statements is true?A. Arctic explorers think it is fun to live on ice for months.B. To Arctic explorers, -60 with high winds and heavy snow is coldestC.

From the passage we learn that ___________.A. it is possible that some scientists working in the Arctic also work in the Antarctic.B. the South Pole' s coldest temperature is still very hot compared with the cold made in acryostat.C. a cryostat can be used to change a very low temperature into a pleasant summer day.D. the Arctic is covered by an unbroken sheet of ice several miles in thickness.10. "Absolute Zero” is ____________.A. no temperature at all. C. as cold as spaceB. an ice-cold valley D. the lowest temperature in earthQuestions 11 to 15 are based on the following passage:The distressing situation of the aged has come to be regarded as a major social problem in the United Sates. In a sense, the elderly (generally, those aged sixty-five and over are a "newly-discovered" minority group. Like other minority groups, the old are subjected to job discrimination(歧视); they suffer high rates of poverty; they are excluded from the mainstream of American life; and they are offered few meaningful roles in their society. In addition, the aged may easily fall victim to criminals, and face chronic(慢性的) illness, heavy medical expenses, and psychological problems that result from their loss of independence and their sense of being unwanted.An industrialized society such as the United States is oriented toward youth, mobility (流动), and activity, It does little to integrate the old into the social structure. Unlike the elders in a traditional society, the American aged can no longer lay automatic claim on their children and relatives for support and social participation; on the contrary, they are more likely to have to try not to be a burden to their now independent adult children. Nor are they regarded as the wisest members of the community as the elders in a traditional society would be. Moreover, retirement often signifies little more than a swift transition(过渡) from a meaningful role to a meaningless one. The transition is not simply from work to leisure. It can also be from affluence to economic hardship. As the American population is growing steadily older when the proportion of its aged members increases, the problems of tile elderly are attracting more and more attention.11. The elderly are a "newly-discovered" minority group because__________.A. there are more aged people among colored people than amongB. this group was not discovered before.C. people noticed their characteristics as a group only recently.D. they have only recently grouped together for their rights.12. Which of the following is NOT true about the problems of the aged in America?A. They develop mental illness as they are no longer wanted by societyB. The cost of medical care is too heavy for them to bearC. They have never been in the mainstream of AmericanD. They are not given fair treatment when seeking jobs.13. The author implies that in a traditional society ________.A. the aged find it hard to integrate themselves into its social structureB. the elderly can naturally expect support from their children.C. youth, mobility and activity are important.D. people grow wiser as they grow older.14. The word "affluence" in Line 10, Paragraph 2 probably means ___________.A. influenceB. fluencyC. flowD. wealth15. The best title for the passage would be ___________.A. Problems of Old Age in America.B. Differences between America and a Traditional Society.C. America‟s Minority Group.D. Old people's Distressing Situation.Questions 16 to 20 are based on the following passage:I was on my way out to lunch from work when the two strangers caught me off guard. I mean, who would expect two clean-cut American types to mug (rob) you n 86th St. and 3rd Avenue. Maybe that made it worse. They were nice-looking guys.One minute they were walking past me; then before I knew what was happening, the big one reached out and grabbed my arm hard. His hand was so big it filled all the way around my arm muscle. I must have looked shocked, because all of a sudden he laughed in my face. He didn't have his two front teeth, for some reason, I keep remembering that.The next thing I knew they had pushed me against the wall of a building. I'm not sure I ever felt it when the other one tore my bag from off my shoulder. The next thing I knew, they were gone.I was so shocked for a while I just stood there looking at the people walking by. It was like nobody even noticed. Then I got the shakes.

Your teeth are a living part of your body. They have nerves and blood vessels. Diseased teeth can cause pain, die, and fall out. False teeth often do not work as well as natural teeth. By knowing what causes dental diseases, you can learn to take proper care of your teeth. If you do take proper care of your teeth, you can keep them your entire life.Plaque is the main enemy of healthy teeth. Everyone has plaque. It is a sticky, colorless film that coats the teeth. Plaque is not removed, it builds up the teeth, especially at the gumline. If plaque is not removed, it builds up and gets under the gumline. Plaque that is left on the teeth for some time hardens. The result is tooth decay and gum disease.The bacteria in plaque live on sugar. They change sugar into acids which break down the tooth‟s hard enamel. If left untreated, decay goes deeper and deeper into the tooth. After a while, the decay reaches the nerves and blood vessels of the inner tooth. By the time this happens, the tooth has probably started to ache.In addition to tooth decay, there are also gum diseases to watch out for. The bacteria in plaque make poisons that attack the gums. Small pockets form around the teeth. The pockets trap more bacteria and food particles. Finally, the bone supporting the teeth is attacked and starts to shrink. Teeth become loose and may fall out. Adults lose most teeth this way.Gum disease starts slowly. There may be no pain. As a rule, gum disease first appears as a swelling. Then the gums become tender. There also may be bleeding. To heal diseased gums, your teeth need one or more dental cleanings. The cleanings must be following by good, regular care. Sometimes, gum disease starts with signs that are not so easy to see.

Short AnswerWhat are some of the steps a person can take to prevent his house from being burglarized (夜间盗窃) while he is away? One step is to make sure that the house has a lived-in look. Living room shades should be pulled down only half-way. Bedrooms that usually have the shades pulled down at bight should be left down.

Lights that turn on and off automatically are the best. Then too, it is a good idea to leave the radio tuned in to a talking station, any type of conversation makes a burglar think twice before trying to enter. Finally, while away on vacation, make sure that nothing collects in the front or in back of the house.
