Often the forms of marriage sanctioned by a
23、 society are related to the needs of that society. 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 p
24、olygamy in which one female is married to more 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 seco
25、nd woman. Not uncommonly in these marriages, the 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 ma
26、rriage because in most societies each wife and 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 o
27、f having more than one wife. Generally it is the 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 compr
28、ession of marriageable ages for men, a larger 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
29、in which two individuals are involvedC.a form 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 peop
30、leB.mostly by young peopleC.more commonlyD.by 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 an
31、d money greatly influenced the probability of 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 so
32、ciety.C.The author thinks that it is unfair to women.D.The author thinks it acceptable.八、Text 2(总题数：1，分数：10.00)It 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 begin
33、s with listening. Individual children vary greatly in the amount 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
34、eager and delighted cooperation usually shown by the child. Before 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
35、agreed hat they enjoy making noises, and that during the first 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 for
36、ms of language. It is agreed, too, that from about three months 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 the
37、n arises as to the point at which one can say that these imitations 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 provid
38、e an adequate explanationD.its high time that an explanation 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).Th
39、e authors purpose in writing the second paragraph is to show 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 diffi
40、culties in learning to speakB.imitation plays an important role 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
41、 Huge Task for ChildrenC.How Babies Learn to SpeakD.Early Forms of Language九、Text 3(总题数：1，分数：10.00)There 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 statist
42、ics come from the same Latin root, status) and a gentlemanly gambling father 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
43、the taking of censusesall of which led to modern descriptive statistics. The 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 eit
44、her quantitative, such as measures of height, intelligence, or grade levelvariables 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 summarizatio
45、n 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 pres
46、ent great difficulties for the unaided human mind. This general class of problems characteristically involves attempts to make predictions using a sample of observations. For example, a school superintendent wishes to determine the proportion of children in a large school system who come to school w
47、ithout breakfast, have been vaccinated against flu, or whatever. Having a little knowledge of statistics, the superintendent would know that it is unnecessary and inefficient to question each child; the proportion for the entire district could be estimated fairly accurately from a sample of as few a
48、s 100 children. Thus, the purpose of inferential statistics is to predict or estimate characteristics of a population from a knowledge of the characteristics of only a sample of the population.（分数：10.00）(1).With what is the passage mainly concerned?（分数：2.00）A.The drawbacks of descriptive and inferen
49、tial statistics.B.Applications of inferential statistics.C.How to use descriptive statistics.D.The development and use of statistics.(2).According to Para. 1, counting and describing are associated with _.（分数：2.00）A.descriptive statisticsB.qualitative changesC.inferential statisticsD.unknown variables(3).Why does the author mention the “mother“ (Para. 1) and “father“ (Para. 1)?（分数：2.00）A.To point out that parents can teach their children statistics.B.To present the background of statistics in a humorous and u
