In the United States, the best-known surveys are the Gallup poll and the Harris poll. As an

2、yone who watches the news during presidential campaigns knows, these polls have become an important part of political life in the United States.North Americans are familiar with the many person-on-the-street interviews on local television news shows. While such interviews can be highly entertaining,

3、 they are not necessarily an accurate indication of public opinion. First, they reflect the opinions of only those people who appear at a certain location. Thus, such samples can be biased in favor of commuters, middle-class shoppers, or factory workers, depending on which area the newspeople select

4、. Second, television interviews tend to attract outgoing people who are willing to appear on the air, while they frighten away others who may feel intimidated by a camera. A survey must be based on a precise, representative sampling if it is to genuinely reflect a broad range of the population.In pr

5、eparing to conduct a survey, sociologists must exercise great care in the wording of questions. An effective survey question must be simple and clear enough for people to understand it. It must also be specific enough so that there are no problems in interpreting the results. Even questions that are

6、 less structured must be carefully phrased in order to elicit the type of information desired. Surveys can be indispensable sources of information, but only if the sampling is done properly and the questions are worded accurately.There are two main forms of surveys: the interview and the questionnai

7、re. Each of these forms of survey research has its advantages. An interviewer can obtain a high response rate because people find it more difficult to turn down a personal request for an interview than to throw away a written questionnaire. In addition, an interviewer can go beyond written questions

8、 and probe for a subjects underlying feelings and reasons. However, questionnaires have the advantage of being cheaper and more consistent.1. What does the passage mainly discuss?(A) The history of surveys in North America(B) The principles of conducting surveys(C) Problems associated with interpret

15、ponse rate (line 24)PASSAGE 80 BCADB ADABA A托福阅读真题2The largest of the giant gas planets, Jupiter, with a volume 1,300 times greater than Earths, contains more than twice the mass of all the other planets combined. It is thought to be a gaseous and fluid planet without solid surfaces, Had it been som

16、ewhat more massive, Jupiter might have attained internal temperatures as high as the ignition point for nuclear reactions, and it would have flamed as a star in its own right. Jupiter and the other giant planets are of a low-density type quite distinct from the terrestrial planets: they are composed

17、 predominantly of such substances as hydrogen, helium, ammonia, and methane, unlike terrestrial planets. Much of Jupiters interior might be in the form of liquid, metallic hydrogen. Normally, hydrogen is a gas, but under pressures of millions of kilograms per square centimeter, which exist in the de

18、ep interior of Jupiter, the hydrogen atoms might lock together to form a liquid with the properties of a metal. Some scientists believe that the innermost core of Jupiter might be rocky, or metallic like the core of Earth.Jupiter rotates very fast, once every 9.8 hours. As a result, its clouds, whic

19、h are composed largely of frozen and liquid ammonia, have been whipped into alternating dark and bright bands that circle the planet at different speeds in different latitudes. Jupiters puzzling Great Red Spot changes size as it hovers in the Southern Hemisphere. Scientists speculate it might be a g

20、igantic hurricane, which because of its large size (the Earth could easily fit inside it), lasts for hundreds of years.Jupiter gives off twice as much heat as it receives from the Sun. Perhaps this is primeval heat or heat generated by the continued gravitational contraction of the planet. Another s

21、tarlike characteristic of Jupiter is its sixteen natural satellites, which, like a miniature model of the Solar System, decrease in density with distance from rocky moons close to Jupiter to icy moons farther away. If Jupiter were about 70 times more massive, it would have become a star, Jupiter is

22、the best-preserved sample of the early solar nebula, and with its satellites, might contain the most important clues about the origin of the Solar System.1. The word attained in line 4 is closest in meaning to(A) attempted(B) changed(C) lost(D) reached2. The word flamed in line 5 is closest in meani

According to the passage , hydrogen can become a metallic-like liquid when it is(A) extremely hot(B) combined with helium(C) similar to atmospheres(D

24、) under great pressures5. According to the passage , some scientists believe Jupiter and Earth are similar in that theyboth have(A) solid surfaces(B) similar masses(C) similar atmospheres(D) metallic cores6. The clouds surrounding Jupiter are mostly composed of(A) ammonia(B) helium(C) hydrogen(D) me

25、thane7. It can be inferred from the passage that the appearance of alternating bands circling Jupiter iscaused by(A) the Great Red Spot(B) heat from the Sun(C) the planets fast rotation(D) Storms from the planets Southern Hemisphere8. The author uses the word puzzling in line 17 to suggest that the

26、Great Red Spot is(A) the only spot of its kind(B) not well understood(C) among the largest of such spots(D) a problem for the planets continued existence9. Paragraph 3 supports which of the following conclusions?(A) Jupiter gives off twice as much heat as the Sun.(B) Jupiter has a weaker gravitation

27、al force than the other planets.(C) Scientists believe that Jupiter was once a star.(D) Scientists might learn about the beginning of the Solar System by Studying Jupiter.10. Why does the author mention primeval heat (lines 21)?(A) To provide evidence that Jupiter is older than the Sun(B) To provide

28、 evidence that Jupiter is older than the other planets(C) To suggest a possible explanation for the number of satellites that Jupiter has(D) To suggest a possible source of the quantity of heat that Jupiter gives off11. According to the passage , Jupiters most distant moon is(A) the least dense(B) t

29、he largest(C) warm on the surface(D) very rocky on the surface12. Which of the following statements is supported by the passage ?(A) If Jupiter had fewer satellites, it would be easier for scientists to study the planet itself.(B) If Jupiter had had more mass, it would have developed internal nuclea

30、r reactions.(C) If Jupiter had been smaller, it would have become a terrestrial planet.(D) if Jupiter were larger, it would give off much less heatPASSAGE 81 DABDD ACBDD AB.托福阅读真题3Ethology is concerned with the study of adaptive, or survival, value of behavior and its evolutionary history. Ethologic

31、al theory began to be applied to research on children in the 1960s but has become even more influential today. The origins of ethology can be traced back to the work of Darwin. Its modern foundations were laid by two European zoologists, Konrad Lorenz and Niko Tinbergen.Watching the behaviors divers

32、e animal species in their natural habitats, Lorenz, and Tinbergen observed behavior patterns that promote survival. The most well-known of these is imprinting, the early following behavior of certain baby birds that ensures that the young will stay close to their mother and be fed and protected from

33、 danger. Imprinting takes place during an early, restricted time period of development. If the mother goose is not present during this time, but an object resembling her in important features is, young goslings may imprint on it instead. Observations of imprinting led to major concept that has been

34、applied in child development the critical period. It refers to a limited times span during which the child is biologically prepared to acquire certain adaptive behaviors but needs the support of suitably stimulating environment. Many researchers have conducted studies to find out whether complex cog

35、nitive and social behaviors must be learned during restricted time periods. For example, if children are deprived of adequate food or physical and social stimulation during the early years of life, will their intelligence be permanently impaired? If language is not mastered during the preschool year

36、s, is the childs capacity to acquire it reduced?Inspired by observations of imprinting, in 1969 the British psychoanalyst John Bowlby applied ethological theory to the understanding of the relationship between an infant and its parents. He argued that attachment behaviors of babies, such as smiling,

37、 babbling, grasping, and crying, are built-in social signals that encourage the parents to approach, care for, and interact with the baby. By keeping a parent near, these behaviors help ensure that the baby will be fed, protected from danger, and provided with the stimulation and affection necessary

38、 for healthy growth. The development of attachment in human infants is a lengthy process involving changes in psychological structures that lead to a deep affectional tie between parent and baby.1. What was Darwins contribution to ethology?(A) Darwin improved on the original principles of ethology.(

39、B) Darwin was the professor who taught Lorenz and Tinbergen.(C) Darwins work provided the basis for ethology.(D) Darwin was the first person to apply ethological theory to children.2. The word diverse in line 6 is closest in meaning to(A) small(B) varied(C) wild(D) particular3. The word ensures in l

40、ine 8 is closest in meaning to(A) guarantees(B) proves(C) teaches(D) assumes4. According to the passage , if a mother goose is not present during the time period whenimprinting takes place, which of the following will most likely occur?(A) The gosling will not imprint on any object.(B) The gosling m

41、ay not find a mate when it matures.(C) The mother will later imprint on the gosling.(D) The gosling may imprint on another object.5. The word it in line 12 refers to(A) development(B) goose(C) time(D) object6. The word suitably in line 16 is closest in meaning to(A) willingly(B) moderately(C) approp

42、riately(D) emotionally7. The author mentions all of the following as attachment behaviors of human infants EXCEPT(A) grasping(B) crying(C) eating(D) smiling8. According to the passage , attachment behaviors of infants are intended to(A) get the physical, emotional and social needs of the infant met(

43、B) allow the infant to become imprinted on objects that resemble the parent(C) provide the infant with a means of self-stimulation(D) prepare the infant to cope with separation9. The phrase affectional tie in line 30 is closest in meaning to(A) cognitive development(B) emotional attachment(C) psycho

44、logical need(D) behavioral change10. It can be inferred from the passage that ethological theory assumes that(A) to learn about human behavior only human subjects should be studied(B) failure to imprint has no influence on intelligence(C) the notion of critical periods applies only to animals(D) there are similarities between animal and human behaviorPASSAGE 82 CBADD CCABD
