Answer th
26、e questions below each text by choosing A, B, C or D. Mark your answer on ANSWER SHEET.BText 1/BAn enormous variety of relationships between men and women, singly and in groups, meet the definition of marriage. Often the forms of marriage sanctioned by a society are related to the needs of that soci
27、ety. Marriage between two individuals, one male and one female, is known as monogamy. Marriage of three or more individuals is known as polygamy.Polygyny is a form of polygamy in which one male is married to more than one female. Polyandry is a form of polygamy in which one female is married to more
28、 than one male. Still another form of polygamy is group marriage, in which two or more males are married to two or more females. In some societies a polyandrous marriage of two men with one woman may become a group marriage through the addition of a second woman. Not uncommonly in these marriages, t
29、he co-husbands are brothers and the added woman is the first wifes sister.In general, polygyny presupposes a considerable accumulation of wealth and is therefore rarely practice. A polygynous marriage requires more economic resources than a monogamous marriage because in most societies each wife and
30、 her children, unless they are sisters, have their own sleeping quarters and sometimes also have their own cooking facilities.Where polygyny exists, it is practiced largely by the wealthy and the ruling classes, because only these can afford the luxury of having more than one wife. Generally it is t
31、he older men, who have lived long enough to acquire capital, who have more than one wife. Younger men have either one wife or none. In some societies where there is an extension of the marriageable ages for women, such as from 13 to 45 years, and a compression of marriageable ages for men, a larger
32、pool of female partners is available, without an overall unbalanced sex ratio. This, too, leads to older men having several wives.（分数：10.00）(1).Polygyny is _.（分数：2.00）A.a form marriage in which at least three individuals are involvedB.a form of marriage in which two individuals are involvedC.a form
33、of marriage in which one female is married to raore than one maleD.Both A and C(2).In a polygamy, two brothers marry two sisters is _.（分数：2.00）A.not allowedB.strangeC.commonD.rare(3).Compared with monogamy, polygamy is practiced _.（分数：2.00）A.by less peopleB.mostly by young peopleC.more commonlyD.by
34、people who have many sisters or brothers(4).What conclusion can we draw from this passage?（分数：2.00）A.Since women between 13 to 45 are eager to find husbands, sometimes they have to marry married men because of the shortage of unmarried men.B.Sex ratio and money greatly influenced the probability of
35、conducting polygamy.C.Polygamy can only be practiced by the older and wealthier men.D.Wealthy men are old men.(5).What is the authors attitude towards polygamy?（分数：2.00）A.The author shows no idea about polygamy.B.The author thinks that it benefits the society.C.The author thinks that it is unfair to
36、 women.D.The author thinks it acceptable.BText 2/BIt is, everyone agrees, a huge task that the child performs when he learns to speak, and the fact that he does so in so short a period of time challenges explanation.Language learning begins with listening. Individual children vary greatly in the amo
37、unt of listening they do before they start speaking, and late starters are often long listeners. Most children will “obey“ spoken instructions some time before they can speak though the word obey is hardly accurate as a description of the eager and delighted cooperation usually shown by the child. B
38、efore they can speak, many children will also ask questions by gesture and by making questioning noises.Any attempt to trace the development from the noises babies make Io their first spoken words leads to considerable difficulties. It is agreed hat they enjoy making noises, and that during the firs
39、t few. months one or two noises sort themselves out as particularly indicative of delight, distress, sociability, and so on. But since these cannot be said to show the babys intention to communicate they can hardly be regarded as early forms of language. It is agreed, too, that from about three mont
40、hs they play with sounds for enjoyment, and that by six months they are able to add new sounds to their repertoire. This selfimitation leads on to deliberate imitation of sounds made or words spoken to them by other people. The problem then arises as to the point at which one can say that these imit
41、ations can be considered as speech.（分数：10.00）(1).By “. challenges explanation“ the author means that _.（分数：2.00）A.no explanation has been made up to nowB.no explanation is necessary for such an obvious phenomenonC.its no easy job to provide an adequate explanationD.its high time that an explanation
42、was provided(2).The third paragraph is mainly about _.（分数：2.00）A.the difficulties of babies in learning to speakB.babies intention to communicateC.babies strong desire to communicateD.the development of babies early forms of language(3).The authors purpose in writing the second paragraph is to show
43、that children _.（分数：2.00）A.learn to speak by listeningB.are passive in the process of learning to speakC.are born cooperativeD.usually obey without asking questions(4).From the passage we learn that _.（分数：2.00）A.children have various difficulties in learning to speakB.imitation plays an important ro
44、le in learning to speakC.children show a strong desire to communicate by making noisesD.early starters can learn to speak within only six months(5).The best title for this passage would be _.（分数：2.00）A.Noise Making and Language LearningB.A Huge Task for ChildrenC.How Babies Learn to SpeakD.Early For
45、ms of LanguageBText 3/BThere were two widely divergent influences on the early development of statistical methods. Statistics had a mother who was dedicated to keeping orderly records of governmental units (state and statistics come from the same Latin root, status) and a gentlemanly gambling father
46、 who relied on mathematics to increase his skill at playing the odds in games of chance. The influence of the mother on the offspring, statistics, is represented by counting, measuring, describing, tabulating, ordering, and the taking of censusesall of which led to modern descriptive statistics. The
47、 influence of the father came modern inferential statistics, which is based squarely on theories of probability.Descriptive statistics involves tabulating, depicting, and describing collections of data. These data may be either quantitative, such as measures of height, intelligence, or grade levelva
48、riables that are characterized by an underlying continuumor the data may represent qualitative variables, such as sex, college major, or personality type. Large masses of data must generally undergo a process of summarization or reduction before they are comprehensible. Descriptive statistics is a tool for describing or summarizing or reducing to comprehensible form the properties of an otherwise unwieldy mass of data.Inferential statistics is a formalized body of methods for solving another class of problems that present great difficulties for the unaided human mind. This general cl
