1、考研英语 156及答案解析(总分:36.00,做题时间:180 分钟)一、Section Use of (总题数:1,分数:1.00)Many theies ccerning the causes of juvenile delinquency (crimes committed by young people) focus either the individual society as the maj ctributing influence. Theies -|_|- the individual suggest that children engage in criminal beha
2、vi -|_|-they were not sufficiently penalized f previous misdeeds that they have learned criminal behavi through -|_|-with others. Theies focusing the role of society suggest that children commit crimes in -|_|- to their failure to rise above their socioecomic status, -|_|- as a rejecti of middle-cla
3、ss values. Most theies of juvenile delinquency have focused children from disadvantaged families, -|_|- the fact that children from wealthy homes also commit crimes. The latter may commit crimes -|_|- lack of adequate parental ctrol. All theies, however, are tentative and are -|_|- to criticism. Cha

F example, changes in the ecomy that -|_|- to fewer job opptunities f youth and rising unemployment -|_|- make gainful employment increasingly difficult to obtain. The resulting disctent may in -|_|- lead me youths into criminal

(1) effect of the countrys growing human population on its wildlife (2) possible reason for the effect (3) your suggestion for wildlife protection (1) effect of the countrys growing human population on its wildlife (2) possible re
8、ason for the effect (3) your suggestion for wildlife protection* (分数:1.00)_三、Section Reading(总题数:4,分数:4.00)Non-indigenous (non-native) species of plants and animals arrive by way of two general types of pathways. First, species having origins outside the United States may enter the country and becom
9、e established either as free-living populations or under human cultivation-for example, in agriculture, horticulture, aquaculture, or as pets. Some cultivated species subsequently escape or are released and also become established as free-living populations. Second, species of either U.S. or foreign
10、 origin and already within the United States may spread to new locales. Pathways of both types include intentional as well as unintentional species transfers. Rates of species movement driven by human transformations of natural environments as well as by human mobility-through commerce, tourism, and
11、 travel-greatly exceed natural rates by comparison. While geographic distributions of species naturally expand or contract over historical time intervals (tens to hundreds of years), species ranges rarely expand thousands of miles or across physical barriers such as oceans or mountains. Habitat modi
12、fication can create conditions favorable to the establishment of non-indigenous species. Soil disturbed in construction and agriculture is open for colonization by non-indigenous weeds, which in turn may provide habitats for the non-indigenous insects that evolved with them. Human-generated changes
13、in fire frequency, grazing intensity, as well as soil stability and nutrient levels similarly facilitate the spread and establishment of non-indigenous plants. When human changes to natural environments span large geographical areas, they effectively create passages for species movement between prev
14、iously isolated locales. The rapid spread of the Russian wheat aphid to fifteen states in just two years following its 1986 arrival has been attributed in part to the prevalence of alternative host plants that are available when wheat is not. Many of these are non- indigenous grasses recommended for
15、 planting on the forty million or more acres enrolled in the U.S. Department of Agriculture Conservation Reserve Program. A number of factors perplex quantitative evaluation of the relative importance of various entry pathways. Time lags often occur between establishment of non-indigenous species an
16、d their detection, and tracing the pathway for a long-established species is difficult. Experts estimate that non-indigenous weeds are usually detected only after having been in the country for thirty years or having spread to at least ten thousand acres. In addition, federal port inspection, althou
17、gh a major source of information on non-indigenous species pathways, especially for agriculture pests, provides data only when such species enter via closely-examined routes. Finally, some comparisons between pathways defy quantitative analysis-for example, which is more “important“: the entry path
18、of one very harmful species or one by which many but less harmful species enter the country? (分数:1.00)(1).Which of the following statements about species movement is best supported by the text?(分数:0.20)A.Human factors affect its rates more than its long-term amount.B.Natural expansions of species ac
19、count for their slow contractions.C.Natural environments created by humans facilitate species movement.D.Long-range species movement relies on the ranges of mans mobility.(2). According to the text, the U.S. Department of Agriculture(分数:0.20)A.is liable for the fast distribution of the Russian wheat
20、 pest.B.failed to isolate the Russian wheat aphid in limited locales.C.provides data about foreign species imported by regulated routes.D.is responsible for introducing harmful plants onto federal lands.(3). Which of the following may best express the chief purpose of the last paragraph.?(分数:0.20)A.
21、To explain the difficulties in tracing the pathways for long-established species.B.To describe the events leading to the detection of non-indigenous species.C.To identify the problems in assessing the weight of entry tracks for foreign species.D.To discuss the role of time lags and geographic expans
22、ion in species detection.(4).It can be inferred that all of the following affect the movement of species EXCEPT(分数:0.20)A.earth fertility.B.import restrictions.C.natural obstacles.D.fire disasters.(5).To determine the entry pathway for a non-native species is LEAST likely to depend on(分数:0.20)A.whet
23、her the species is considered to be a pest.B.whether the species enters by a closely-checked route.C.the rate at which the species extends geographically.D.the magnitude of the average number of the species.Modern technology and science have produced a wealth of new materials and new ways of using o
24、ld materials. For the artist this means wider opportunities. There is no doubt that the limitations of materials and nature of tools both restrict and shape a mans work. Observe how the development of plastics and light metals along with new methods of welding has changed the direction of sculpture.
