21、on Readi(总题数：3，分数：15.00)BText 1/BHowever important we may regard school life to be there is no gainsaying the fact that children spend more time at home than in the classroom. Therefore, the great influence of parents cannot be ignored or discounted by the teachers. They can become strong allies of
22、the school personnel or they can consciously or unconsciously hinder and thwart curricular objectives.Administrators have been aware of the need to keep parents apprised of the newer methods used in schools. Many principals have conducted workshops explaining such matters as the reading readiness pr
23、ogram, manuscript writing, and developmental mathematics.Moreover, the classroom teacher, with the permission of the supervisors, can also play an important role in enlightening parents. Many interviews carried on during the year as well as new ways of reporting pupils progress, can significantly ai
24、d in achieving a harmonious interplay between school and home.To illustrate, suppose that a father has been drilling Junior in arithmetic processes night after night. In a friendly interview, the teacher can help the parent sublimate his natural paternal interest into productive channels. He might b

26、onable to assume that he will soon realize his son is making satisfactory progress in mathematics and, at the same time, enjoying the work.Too often, however, teachers conferences with parents are devoted to petty accounts of childrens misdemenanors, complaints about laziness and poor work habits, a
27、nd suggestions for penalties and rewards at home.What is needed in a more creative approach in which the teacher, as a professional adviser, plants ideas in parents minds for the best utilization of many hours that the child spends out of the classroom.In this way, the school and the home join force

31、to the developmental programC.believes that schools are lacking in guidance personnelD.feels that parent-teacher interviews can be made much more constructive than they are at home(4).A method of parent-teacher communication NOT mentioned or referred to by the author is _.（分数：1.00）A.classes for pare

33、lance of the Earth by acting as a one-way screen. Although these molecules allow radiation at visible wavelengths, where most of the energy of sunlight is concentrated, to pass through, they absorb some of the longer-wavelength, infrared emissions radiated from the Earths surface, radiation that wou
34、ld otherwise be transmitted back into space. For the Earth to maintain a constant average temperature, such emissions from the planet must balance incoming solar radiation. If there were no carbon dioxide in the atmosphere, heat would escape from the Earth much more easily. The surface temperature w
35、ould be so much lower that the oceans might be a solid mass of ice.Today, however, the potential problem is too much carbon dioxide. The burning of fossil fuels and the cleaning of forests have increased atmospheric carbon dioxide by about 15 percent in the last hundred years and we continue to add
36、carbon dioxide to the atmosphere. Could the increase in carbon dioxide cause a global rise in average temperature, and could such a rise have serious consequences for human society? Mathematical models that allow us to calculate the rise in temperature as a function of the increase indicate that the
37、 answer is probably “yes“.Under present conditions a temperature of -8 can be observed at an altitude of 5 to 6 kilometers above the Earth. Below this altitude (called the radiating level), the temperature increases by about 6 per kilometer approaching the Earths surface, where the average temperatu
38、re is about 15. An increase in the amount of carbon dioxide means that there are more molecules of carbon dioxide to absorb infrared radiation. As the capacity of the atmosphere to absorb infrared radiation increase, the radiating level and the temperature of the surface must rise.One mathematical m
39、odel predicts that doubling the atmosphere carbon dioxide would raise the global mean surface temperature by 2.5. This model assumes that the atmospheres relative humidity remains constant and the temperature decreases with altitude at a rate of 6.5 per kilometer. The assumption of constant relative
40、 humidity is important, because water vapor in the atmosphere is another efficient absorber of radiation at infrared wavelengths. Because warm air can hold more moisture than cool air, the relative humidity will be constant only if the amount of water vapor in the atmosphere increases as the tempera
41、ture rises. Therefore, more infrared radiation would be absorbed and reradiated back to the Earths surface. The resultant warming at the surface could be expected to melt snow and ice, reducing the Earths reflectivity. More solar radiation would then be absorbed, leading to a further increase in tem
42、perature.（分数：5.00）(1).According to the passage, the greatest part of the solar energy that reaches the Earth is _.（分数：1.00）A.concentrated at visible wavelengthsB.absorbed by carbon dioxide moleculesC.absorbed by atmospheric water vaporD.reflected back to space by snow and ice(2).According to the pas
43、sage, atmospheric carbon dioxide performs all of the following functions EXCEPT _.（分数：1.00）A.absorbing radiation at visible wavelengthsB.absorbing infrared radiationC.absorbing outgoing radiation from the EarthD.helping to retain heat near the Earths surface(3).Which of the following best describes
44、the authors attitude toward the increasing amount of carbon dioxide in the atmosphere and its consequences?（分数：1.00）A.Incredulous.B.Interested but skeptical.C.Angry yet resigned.D.Objective yet concerned(4).It can be concluded from information contained in the passage that the average temperature at
45、 an altitude of 1 kilometer above the Earth is about _.（分数：1.00）A.15B.9C.25D.-18(5).According to the passage, which of the following is true of the last hundred years?（分数：1.00）A.Fossil fuels were burned for the first time.B.The average temperature at the Earths surface has become 2 cooler.C.The amou
46、nt of carbon dioxide in the atmosphere has increased measurably.D.The amount of farmland worldwide has doubled.BText 3/BFoods are overwhelmingly the most advertised group of all consumer products in the United States. Food products lead in expenditures for network and spot television advertisements,
47、 discount coupons, trading stamps, contests, and other forms of premium advertising. In other media newspapers, magazines, newspaper supplements, billboards, and radio food advertising expenditures rank near the top. Food manufacturers spend more on advertising than any other manufacturing group, and the nations grocery stores rank first among all retailers.Through the 1970
