15、e as much. (S9) _. All the people we interviewed expressed almost total satisfaction with it. (S10) _.Part II Reading Comprehension (35 minutes)Directions: There are 4 passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices

16、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 center.Passage OneQuestions 11 to 15 are based on the following passage.Scratchy throats, stuffy noses and body aches all spell misery, but being able t

17、o tell if the cause is a cold or flu (流感) may make a difference in how long the misery lasts.The American Lung Association (ALA) has issued new guidelines on combating colds and the flu, and one of the keys is being able to quickly tell the two apart. Thats because the prescription drugs available f

18、or the flu need to be taken soon after the illness sets in. As for colds, the sooner a person starts taking over-the-counter remedy, the sooner relief will come.The common cold and the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three vir

19、usesflu A, B and C. There is no cure for either illness, but the flu can be prevented by the flu vaccine (疫苗), which is, for most people, the best way to fight the flu, according to the ALA.But if the flu does strike, quick action can help. Although the flu and common cold have many similarities, th

20、ere are some obvious signs to look for.Cold symptoms such as stuffy nose, runny nose and scratchy throat typically develop gradually, and adults and teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu for all ages. And in general, flu symptoms in

21、cluding fever and chills, sore throat and body aches come on suddenly and are more severe than cold symptoms.The ALA notes that it may be particularly difficult to tell when infants and preschool age children have the flu. It advises parents to call the doctor if their small children have flu-like s

22、ymptoms.Both cold and flu symptoms can be eased with over-the-counter medications as well. However, children and teens with a cold or flu should not take aspirin for pain relief because of the risk of Reye syndrome (综合症)，a rare but serious condition of the liver and central nervous system.There is,

23、of course, no vaccine for the common cold. But frequent hand washing and avoiding close contact with people who have colds can reduce the likelihood of catching one.11. According to the author, knowing the cause of the misery will help _.A) shorten the duration of the illnessB) the patient buy medic

24、ine over the counterC) the patient obtain cheaper prescription drugsD) prevent people from catching colds and the flu12. We learn from the passage that _.A) one doesnt need to take any medicine if he has a cold or the fluB) aspirin should not be included in over-the-counter medicines for the fluC) d

25、elayed treatment of the flu will harm the liver and central nervous systemD) over-the-counter drugs can be taken to ease the misery caused by a cold or the flu13. According to the passage, to combat the flu effectively, _.A) one should identify the virus which causes itB) one should consult a doctor

26、 as soon as possibleC) one should take medicine upon catching the diseaseD) one should remain alert when the disease is spreading14. Which of the following symptoms will distinguish the flu from a cold?A) A stuffy nose.B) A high temperature.C) A sore throat.D) A dry cough.15. If children have flu-li

27、ke symptoms, their parents _.A) are advised not to give them aspirinB) should watch out for signs of Reye syndromeC) are encouraged to take them to hospital for vaccinationD) should prevent them from mixing with people running a feverPassage TwoQuestions 16 to 20 are based on the following passage.I

28、n a time of low academic achievement by children in the United States, many Americans are turning to Japan, a country of high academic achievement and economic success, for possible answers. However, the answers provided by Japanese preschools are not the ones Americans expected to find. In most Jap

29、anese preschools, surprisingly little emphasis is put on academic instruction. In one investigation, 300 Japanese and 210 American preschool teachers, child development specialists, and parents were asked about various aspects of early childhood education. Only 2 percent of the Japanese respondents

30、(答问卷者) listed “to give children a good start academically” as one of their top three reasons for a society to have preschools. In contrast, over half the American respondents chose this as one of their top three choices. To prepare children for successful careers in first grade and beyond, Japanese

31、schools do not teach reading, writing, and mathematics, but rather skills such as persistence, concentration, and the ability to function as a member of a group. The vast majority of young Japanese children are taught to read at home by their parents.In the recent comparison of Japanese and American

32、 preschool education, 91 percent of Japanese respondents chose providing children with a group experience as one of their top three reasons for a society to have preschools. Sixty-two percent of the more individually oriented (强调个性发展的) Americans listed group experience as one of their top three choi

33、ces. An emphasis on the importance of the group seen in Japanese early childhood education continues into elementary school education.Like in America, there is diversity in Japanese early childhood education. Some Japanese kindergartens have specific aims, such as early musical training or potential

34、 development. In large cities, some kindergartens are attached to universities that have elementary and secondary schools. Some Japanese parents believe that if their young children attend a university-based program, it will increase the childrens chances of eventually being admitted to top-rated sc

35、hools and universities. Several more progressive programs have introduced free play as a way out for the heavy intellectualizing in some Japanese kindergartens.16. We learn from the first paragraph that many Americans believe _.A) Japanese parents are more involved in preschool education than Americ

36、an parentsB) Japans economic success is a result of its scientific achievementsC) Japanese preschool education emphasizes academic instructionD) Japans higher education is superior to theirs17. Most Americans surveyed believe that preschools should also attach importance to _.A) problem solvingB) gr

37、oup experienceC) parental guidanceD) individually-oriented development18. In Japans preschool education, the focus is on _.A) preparing children academicallyB) developing childrens artistic interestsC) tapping childrens potentialD) shaping childrens character19. Free play has been introduced in some

38、 Japanese kindergartens in order to _.A) broaden childrens horizonB) cultivate childrens creativityC) lighten childrens study loadD) enrich childrens knowledge20. Why do some Japanese parents send their children to university-based kindergartens?A) They can do better in their future studies.B) They

39、can accumulate more group experience there.C) They can be individually oriented when they grow up.D) They can have better chances of getting a first-rate education.Passage ThreeQuestions 21 to 25 are based on the following passage.Lead deposits, which accumulated in soil and snow during the 1960s an

40、d 70s, were primarily the result of leaded gasoline emissions originating in the United States. In the twenty years that the Clean Air Act has mandated unleaded gas use in the United States, the lead accumulation worldwide has decreased significantly.A study published recently in the journal Nature

41、shows that air-borne leaded gas emissions from the United States were the leading contributor to the high concentration of lead in the snow in Greenland. The new study is a result of the continued research led by Dr. Charles Boutron, an expert on the impact of heavy metals on the environment at the

42、National Center for Scientific Research in France. A study by Dr. Boutron published in 1991 showed that lead levels in arctic (北极的) snow were declining.In his new study, Dr. Boutron found the ratios of the different forms of lead in the leaded gasoline used in the United States were different from t

43、he ratios of European, Asian and Canadian gasolines and thus enabled scientists to differentiate (区分) the lead sources. The dominant lead ratio found in Greenland snow matched that found in gasoline from the United States.In a study published in the journal Ambio, scientists found that lead levels i

44、n soil in the Northeastern United States had decreased markedly since the introduction of unleaded gasoline.Many scientists had believed that the lead would stay in soil and snow for a longer period.The authors of the Ambio study examined samples of the upper layers of soil taken from the same sites

45、 of 30 forest floors in New England, New York and Pennsylvania in 1980 and in 1990. The forest environment processed and redistributed the lead faster than the scientists had expected.Scientists say both studies demonstrate that certain parts of the ecosystem (生态系统) respond rapidly to reductions in

46、atmospheric pollution, but that these findings should not be used as a license to pollute.21. The study published in the journal Nature indicates that _.A) the Clean Air Act has not produced the desired resultsB) lead deposits in arctic snow are on the increaseC) lead will stay in soil and snow long

47、er than expectedD) the US is the major source of lead pollution in arctic snow22. Lead accumulation worldwide decreased significantly after the use of unleaded gas in the US _.A) was discouragedB) was enforced by lawC) was prohibited by lawD) was introduced23. How did scientists discover the source

48、of lead pollution in Greenland?A) By analyzing the data published in journals like Nature and Ambio.B) By observing the lead accumulations in different parts of the arctic area.C) By studying the chemical elements of soil and snow in Northeastern America.D) By comparing the chemical compositions of leaded gasoline used in various countries.24. The authors of the Ambio study have found that _.A) forests get r
