Good cards

10、 will help those who have them to have a long and healthy existence, while bad cards will bring to those who have them terrible diseases like high blood pressure and heart disease. Occasionally, cards are dealt out that doom their holders to an early death. In the past, people never knew exactly whi

11、ch cards they had been dealt. They could guess at the future only by looking at the kind of health problems experienced by their parents or grandparents.Genetic testing, which makes it possible to find dangerous genes, has changed all this. But, until recently, if you were tested positive for a bad

12、gene you were not obliged to reveal this to anyone else except in a few extreme circumstances. This month, however, Britain became the first country in the world to allow life insurers to ask for test results.So far, approval has been given only for a test for a fatal brain disorder known as Hunting

13、tons disease. But ten other tests (for seven diseases) are already in use and are awaiting similar approval.The independent body that gives approval, the Department of Healths genetics and insurance committee, does not have to decide whether the use of genetic information in insurance is ethical. It

14、 must judge only whether the tests are reliable to insurers. In the case of Huntingtons disease the answer is clear-cut. People unlucky enough to have this gene will die early, and cost life insurers dearly.This is only the start. Clear-cut genetic answers, where a gene is simply and directly relate

15、d to a persons risk of death, are uncommon. More usually, a group of genes is associated with the risk of developing a common disease, dependent on the presence of other genetic or environmental factors. But, as tests improve, it will become possible to predict whether or not a particular individual

16、 is at risk. In the next few years researchers will discover more and more about the functions of individual genes and what health risks or benefits are associated with them.（分数：10.00）(1).What does the word “cards” (Line 1, Para. 1) refer to?（分数：2.00）A.Diseases.B.Genes.C.Problems.D.Tests.(2).The fun

17、ction of genetic testing is（分数：2.00）A.to enable people to change genes.B.to help people to create good genes.C.to predict diseases people may have.D.to detect accurately what diseases people may develop.(3).Health authorities allow insurers to use genetic information for the purpose of（分数：2.00）A.imp

18、roving genetic testing technology.B.safeguarding patients interests.C.promoting disease prevention,D.reducing insurance payments.(4).Which of the following statements is true according to the text?（分数：2.00）A.Genes may contribute to some common diseases.B.Environmental factors cause more diseases tha

19、n genes.C.It is common that most fatal diseases are caused by genes.D.It is impossible to get clear-cut genetic answers.(5).The authors purpose in writing the passage is（分数：2.00）A.to indicate the way genetic testing works.B.to show the power of ones genetic makeup.C.to introduce genetic testing and

20、its function.D.to reveal the influence of environment on genes.五、Text 2(总题数：1，分数：10.00)Good teachers matter. This may seem obvious to anyone who has a child in school or, for that matter, to anyone who has been a child in school. For a long time, though, researchers couldnt actually prove that teach

21、ing talent was important. But new research finally shows that teacher quality is a close cousin to student achievement: A great teacher can cram one-and-a-half grades worth of learning into a single year, while laggards are lucky to accomplish half that much.Yet, while we know now that better teache

22、rs are critical, flaws in the way that administrators select and retain them mean that schools dont always hire the best.Failing to recognize the qualities that make teachers truly effective and to construct incentives to attract and retain more of these top performers has serious consequences. High

23、er salaries draw more weak as well as strong applicants into teaching applicants the current hiring system cant adequately screen. Unless administrators have incentives to hire the best teachers available, its pointless to give them a larger group to choose from. Study after study has shown that tea

24、chers with masters degrees are no better than those without. Job experience does matter, but only for the first few years, according to research by Hoover Institutions Eric A. Hanushek. A teacher with 15 years of experience is no more effective, on average, than a teacher with five years of experien

25、ce, but which one do you think is paid more?This toxic combination of rigid pay and steep rewards for seniority causes average quality to decline rather than increase as teacher groups get older. Top performers often leave the field early for industries that reward their excellence. Mediocre teacher

26、s, on the other hand, are soon overcompensated by seniority pay. And because they are paid more than their skills command elsewhere, these less-capable pedagogues settle in to provide many years-of ineffectual instruction.So how can we separate the wheat from the chaff in the teaching profession? To

27、 make American schools competitive, we must rethink seniority pay, the value of masters degrees, and the notion that a teacher can teach everything equally well especially math and science without appropriate preparation in the subject.Our current education system is unlikely to accomplish this dram

28、atic rethinking. Imagine, for a moment, that American cars had been free in recent decades, while Toyotas and Hondas sold at full price. Wed probably be driving Falcons and Corvairs today. Free public education suffers from a lack of competition in just this way. So while industries from aerospace t

29、o drugs have transformed themselves in order to compete, public schooling has stagnated.School choice could spark the kind of reformation this industry needs by motivating administrators to hire the best and adopt new strategies to keep top teachers in the classroom. The lesson that good teachers ma

30、tter should be taught, not as a theory, but as a practice.（分数：10.00）(1).The beginning sentence “Good teachers matter.” probably means that（分数：2.00）A.good teachers help students establish confidence.B.good teachers determine the personality of students.C.good teachers promote student achievement.D.go

31、od teachers treat students as their own children.(2).According to the author, seniority pay favors（分数：2.00）A.good teachers with masters degrees.B.young and effective teachers.C.experienced and effective teachers.D.mediocre teachers of average quality.(3).The expression “separate the wheat from the c

32、haff in the teaching profession” is closest in meaning to（分数：2.00）A.distinguish better teachers from less capable ones.B.differentiate young teachers from old ones.C.tell the essential qualities of good teaching.D.reevaluate the role of senior teachers.(4).By citing the example of the automobile ind

33、ustry, the author intends to argue that（分数：2.00）A.Japans auto industry is exceeding Americas auto industry.B.the public schooling has stagnated because of competition.C.the current American education system is better than the Japanese one.D.competition must be introduced into the public education sy

34、stem.(5).According to the text, which of the following is true?（分数：2.00）A.Its always true that teachers quality is important.B.Salaries in school are higher than those in other industries.C.The average quality of the teachers in America is declining.D.Administrators have many effective ways to choos

35、e best teachers.六、Text 3(总题数：1，分数：10.00)To understand how astrology works, we should first take a quick look at the sky. Although the stars are at enormous distances, they do indeed give the impression of being affixed to the inner surface of a great hollow sphere surrounding the earth. Ancient peop

36、le, in fact, literally believed in the existence of such a celestial sphere. As the earth spins on its axis, the celestial sphere appears to turn about us each day, pivoting at points on a line with the earths axis of rotation. This daily turning of the sphere carries the stars around the sky, causi

37、ng most of them to rise and set, but they, and constellations they define, maintain fixed patterns on the sphere, just as the continent of Australia maintains its shape on a spinning globe of the earth. Thus the stars were called fixed stars.The motion of the sun along the ecliptic is, of course, me

38、rely a reflection of the revolution of the earth around the sun, but the ancients believed the earth was fixed and the sun had an independent motion of its own, eastward among the stars. The glare of sunlight hides the stars in daytime, but the ancients were aware that the stars were up there even a

39、t night, and the slow eastward motion of the sun around the sky, at the rate of about thirty degrees each month, caused different stars to be visible at night at different times of the year.The moon, revolving around the earth each month, also has an independent motion in the sky. The moon, however

40、changes it position relatively rapidly. Although it appears to rise and Set each day, as does nearly everything else in the sky, we can see the moon changing position during as short an interval as an hour or so. The moons path around the earth lies nearly in the same plane as the earths path around

41、 the sun, so the moon is never seen very far from the ecliptic in the sky. There are five other objects visible to the naked eye that also appear to move in respect to the fixed background of stars on the celestial sphere. These are the planets Mercury, Venus, Mars, Jupiter, and Saturn. All of them

42、revolve around the sun in nearly the same plane as the earth does. So they, like the moon, always appear near the ecliptic. Because we see the planets from the moving earth, however, they behave in a complicated way, with their apparent motions on the celestial sphere reflecting both their own indep

43、endent motions around the sun and our motion as well.（分数：10.00）(1).The ancient people believed that（分数：2.00）A.the earth was spinning on the axis of the sky.B.the patterns of stars on the sky would never change.C.the sky was a hollow sphere spinning around the earth.D.the stars around the sky were no

44、t stationary.(2).It was stated in astrology that（分数：2.00）A.the stun is so distant from us that it was hard to follow its motion.B.the motion of the sun is similar to the revolution of the earth around the sun.C.the motion of the sun is at the rate of about thirty degrees every week.D.the sun was mov

45、ing westward around the sky.(3).Which of the following is true about the motion of the moon?（分数：2.00）A.The moon and the sun are moving in the same place.B.The moon revolved along the ecliptic.C.The moon moves faster than the sun.D.The position of the moon can be found changed in an hours time.(4).Ac

46、cording to the last paragraph, five other planets（分数：2.00）A.always appear near the path of the sun.B.arent moving around the sun as independently as the earth does.C.are moving in a way that can not be recognized.D.are moving around the sun at the same speed as the earth does.(5).According to the te

47、xt, which of the following is true?（分数：2.00）A.Scientists can tell the motion of the earth from the motions of five other planets.B.A fixed star refers to a star that is always stationary on the sky.C.Ancient people had scant knowledge about the movement of the stars.D.All the stars on the sky can be

48、 seen all year long.七、Text 4(总题数：1，分数：10.00)Here is a quick way to spoil a Brussels dinner party. Simply suggest that world governance is slipping away from the G20, G7, G8 or other bodies in which Europeans may hog up to half the seats. Then propose, with gloomy relish, that the future belongs to t

49、he G2: newly fashionable jargon for a putative body formed by China and America.The fear of irrelevance haunts Euro-types, for all their public boasting about Europes future might. The thought that the European Union might not greatly interest China is especially painful. After all, the 21st century was meant to be different. Indeed, to earlier leaders like Frances Jacques Chirac, a rising China was welcome as another challenge to American hegemony, ushering in a “multipolar world” in which the EU would play a big role. If that meant kow-towing t
