22、upation for (13) real or imagined prestige.

23、on or a white-collar job is no good (16) for choosing it as lifes work. (17) , these occupations are not always well paid, since a large (18) of jobs are in mechanical and manual work, the (19) of young people should give serious (20) to these fields.（分数：70.00）(1).A. identificationB. entertainmentC.

24、 accommodationD. occupation（分数：3.50）A.B.C.D. 解析：名词辨析。根据首句可知，本文的主题是 career(职业)，此处应选其近义词 occupation。(2).A. however B. thereforeC. though D. thereby（分数：3.50）A. B.C.D.解析：连词辨析。前句讲理想状态下应该在中学选课之后就确定职业，空格后的句子讲大多数人一生要择业多次，可见空格前后是转折关系，故选 however。(3).A. entirely B. mainlyC. partly D. possibly（分数：3.50）A.B.C. D.

25、解析：副词辨析。空格所在的句子讲人们多次择业的原因，由 because of.and partly to可知 and前后是两个并列关系的原因，因此前半部分也应填入 partly，与后半部分出现的 partly 相呼应，以保证语义和结构的完整。(4).A. fade B. vanishC. survive D. exist（分数：3.50）A.B.C.D. 解析：动词辨析。前句讲到人一生要换很多份工作，由此可以推断出完美的工作并不存在，因此应在 not后填入表示“存在”的词，故选 exist。fade 意为“凋谢，消失”；vanish 意为“消失”；survive 意为“幸存”。(5).A. s

26、ince B. thereforeC. furthermoreD. moreover（分数：3.50）A.B. C.D.解析：副词辨析。前面讲完美的工作并不存在，本句说人们应该参加一些灵活的培训项目，故此处应选表示因果关系的副词，答案选 therefore(因此)。 since 意为“由于”，后接原因；furthermore 意为“此外，而且”，表递进；moreover 意为“些外，而且”。(6).A. make B. fitC. take D. leave（分数：3.50）A.B. C.D.解析：动词辨析。that 引导的从句修饰 training program，根据常识，这种培训应该使人

27、符合某种行业的要求，符合结构与句意的只有 fit(适合)，fit sbfor sth,意为“使某人适合某事”。(7).A. job B. wayC. means D. company（分数：3.50）A. B.C.D.解析：名词辨析。本句的 rather than 表明前后为并列关系，句意为：年轻人应该参加一些广泛而灵活的培训，使他们能胜任某一领域的工作，而不是一项单一的工作。此处 Job 是句中 work 的近义复现。(8).A. with B. forC. without D. to（分数：3.50）A.B.C. D.解析：介词辨析。本句讲年轻人的职业规划，根据本句第一个单词 unfort

28、unately 可判断应填表示否定的单词，故选 without，本句意为：他们的职业规划没有得到职业顾问或心理专家的帮助。(9).A. competent B. competitiveC. aggressive D. effective（分数：3.50）A. B.C.D.解析：形容词辨析。此处填入的应是 vocational counselor or psychologist(职业顾问或心理专家)的定语。对于寻求帮助的年轻人而言，最重要的是专家有无水平，故选 competent(有能力的，胜任的)。competitive 意为“有竞争力的”；aggressive 意为“有进取心的”；effec

29、tive 意为“有效率的”。(10).A. little B. fewC. much D. more（分数：3.50）A. B.C.D.解析：形容词辨析。此处应填 know 的宾语。根据句尾的 hit-or-miss(无计划的，无目的的)可以推断，很多年轻人对 occupational world 知之甚少，而且 occupational world 是不可数名词，故选 little。(11).A. turn B. driftC. leave D. float（分数：3.50）A.B. C.D.解析：动词辨析。本句意为：有些人不停地换工作，此处填入的词应与 from 构成固定搭配，所以只能选d

30、rift。drift from work to work 意为“不停换工作”。(12).A. apply B. appealC. stick D. turn（分数：3.50）A.B.C. D.解析：动词辨析。本句要结合上句进行判断。这两句使用了“SomeOthers”句型，句意应该相反。前一句是有些人频繁换工作，后一句应是有些人不换工作，故选 stick(to)(坚持)。(13).A. our B. itsC. your D. their（分数：3.50）A.B. C.D.解析：代词辨析。根据后文，此处的 prestige 指工作特征而非人的特征，因此应填 its。(14).A. concer

31、ningB. followingC. consideringD. disregarding（分数：3.50）A.B.C.D. 解析：动词辨析。后面提到很多高中生或者其家长帮他们选择工作领域，空格后说这类职业从业者较少或对个人要求很高，由此可知他们的选择是盲目的，没有从客观实际出发，故选 disregarding(忽视，漠视)。(15).A. preferencesB. requirementsC. tendencies D. ambitions（分数：3.50）A.B. C.D.解析：名词辨析。此处应填可以被 high 修饰的词，表示专业工作的实际情况，故选 requirements(要求)，

32、指胜任这些工作所需的技能要求很高。preferences 意为“优先选择”；tendencies 意为“倾向”；ambitions 意为“雄心”。(16).A. resource B. backgroundC. reason D. basis（分数：3.50）A.B.C. D.解析：名词辨析。此句表示工作的声望好并不能成为选择作为终身职业的好理由，故选rcason。resource 意为“来源”；background 意为“背景”；basis 意为“基础”。(17).A. Therefore B. NeverthelessC. However D. Moreover（分数：3.50）A.B.C

33、.D. 解析：逻辑关系。本句意为：这些工作不一定报酬都很高，与空格前的句子是递进关系，故选moreover。(18).A. rate B. thicknessC. proportionD. density（分数：3.50）A.B.C. D.解析：名词辨析。此处所填的词应该能构成“aof”的结构，表示“一部分”，只有 proportion(部分)符合题意。rate 意为“速度，比例”；thickness 意为“厚度，浓度”；density 意为“密度”。(19).A. majority B. massC. minority D. multitude（分数：3.50）A. B.C.D.解析：名词辨

34、析。此处提醒年轻人要认真考虑这类工作，当然提醒的是大多数人，而非少数人，故选majority。(20).A. proposal B. suggestionC. considerationD. appraisal（分数：3.50）A.B.C. D.解析：名词辨析。根据上题，作者提醒年轻人认真考虑此事，故选 consideration (考虑，顾虑)。proposal 意为“提议，建议”；suggestion 意为“建议”； appraisal 意为“评价，评估”。二、强化训练二(总题数：1，分数：70.00)Mars is not, it seems, the dry old planet we

35、 once believed it to be. Astronauts who are (1) to go there in the next decade may find plenty (2) water to slake(消除) their thirst.And with water present the (3) of finding some sort of life on Mars are (4) brighter.This is the view of 40 (5) all over the world who have been analyzing (6) of picture

36、s and other scientific (7) obtained by robot explorers in the sixties and seventies.To begin with, scientists thought the Red Planet was as (8) as the Moon with dust storms swirling over vast sandy (9) . But now the picture is very different with mountains and valleys carved by (10) glaciers and tor

37、rential rivers rushing and rumbling deep underground.In a report on the (11) of the Martian pictures Dr. Michael Car of the U.S. Geological Survey comments, “I am (12) theres lots of water on Mars.“ Any surface water will be in the (13) of ice. But it could (14) explorers having to take so much fres

38、h (15) with them.The report says (16) Mars probably had a warmer climate in ages (17) due to its axis having been more steeply tilted towards the Sun.(18) convincing signs of plant or animal life have been (19) by instruments soft. landed on Mars, (20) only the immediate vicinity of landing vehicles

39、 could be examined.（分数：70.00）(1).A. expected B. hopedC. required D. eager（分数：3.50）A. B.C.D.解析：词义辨析。expect sbto do sth意为“期望某人做某事”，常用于被动语态。 hope 意为“希望”，不能用于“宾语+宾语补足语”的结构；require 意为“命令”，其用法为 require sbto do sth.；eager 意为，“渴望的”，是形容词，be eager to do sth意为“渴望做某事”，不符合题意。(2).A. to B. ofC. more D. in（分数：3.50）

40、A.B. C.D.解析：固定搭配。plenty of(许多)是固定搭配，其后可接不可数名词或可数名词复数。(3).A. chances B. openingsC. occasions D. opportunities（分数：3.50）A. B.C.D.解析：名词辨析。本句意为：有了水的存在，在火星上发现某种生命的更有希望。由于第二个空格要填入的是比较级的修饰词，所以该空格不影响对句子的理解，因此只要集中判断第一个空格即可。chances 意为“可能性”；opening 意为“职位的空缺；有利的环境”；occasion 意为“合适时机”； opporturnity 意为“机会”，侧重指做某事的条

41、件或时机。(4).A. quite B. veryC. much D. more（分数：3.50）A.B.C. D.解析：语法结构。四个选项中，只有 much 可以修饰形容词或副词的比较级，表示比较的程度。(5).A. biologists B. geologistsC. sociologistsD. psychologists（分数：3.50）A.B. C.D.解析：名同辨析。根据常识，研究火星的应是 geologist(地质学家)。biologist 意为“生物学家”；sociologist 意为“社会学家”；psychologist 意为“心理学家”。(6).A. lots B. qua

42、ntifiesC. thousand D. thousands（分数：3.50）A.B.C.D. 解析：固定搭配。“_ of pictures”和“other scientific_”是并列结构，由表被动语态的过去分词短语 obtained by robot explorers修饰，根据常识，机器人探测器在六七十年代获取的照片应该非常多，所以第一个空格处应该填入 thousands of(许多的，成千上万的)，来表达“极多”的含义。(7).A. tidings B. newsC. intelligenceD. information（分数：3.50）A.B.C.D. 解析：名词辨析。由于 an

43、d 连接的是并列结构，所以此处应该填入一个与 picture 对应的能够用scientific 修饰的词，所以答案是 information，scientific information 表示“科技信息”。intelligence 多指市场信息和军事情报。(8).A. peaceful B. quietC. lifeless D. dead（分数：3.50）A.B.C. D.解析：形容词辨析。从选项判断空格处要填入一个形容词，来描述科学家们最初认为的火星与月亮的一个共同特点。结合第二段提到的由于水的存在，在火星上寻找某种生命的希望更大了，可知科学家们最初认为火星上是没有生命的，故填 lifel

44、ess(死气沉沉的，没有生命的)。(9).A. deserts B. mountainsC. seas D. rivers（分数：3.50）A. B.C.D.解析：名词辨析。根据空格前的 dust storms swirling vast sandy可以推断描述的是沙漠的景象，故选 deserts。(10).A. energeticB. greatC. massive D. mighty（分数：3.50）A.B.C.D. 解析：形容词辨析。由选项可知，空格处要填入一个形容词来修饰 glaciers(冰川)。energetic 意为“精力旺盛的，充沛的”；great 侧重指数量、尺寸或程度上的“

45、大”；massive 侧重指尺寸或数量上的巨大。mighty 指力量上的强大。结合文意，正确答案应该是 D。(11).A. diagnosis B. synthesesC. analysis D. analyses（分数：3.50）A.B.C. D.解析：名词辨析，结合选项和句意分析，空格处应该填入一个名词，并且该名词的动词形式能够与 the Martian pictures 搭配，故而可以首先排除 diagnosis (诊断)。systheses(综合)是指将不同的事物或观点合在一起，使之成为一个新的整体，与文意不符，故也可以排除。此处只能选 analysis(分析)。(12).A. con

46、vinced B. guaranteedC. believed D. proved（分数：3.50）A. B.C.D.解析：动词辨析，I am convinced意为“我被说服相信”。guarantee 意为“保证”，believe 意为“相信”，一般不用于被动语态；proved 不合题意，不能说“我被证明”。(13).A. appearance B. mouldC. form D. shape（分数：3.50）A.B.C. D.解析：名词辨析。根据常识，冰是水的一种存在形式，所以选 form。appearance 意为“外表，外观”；mould 意为“铸模，模子”；shape 意为“外形，形

47、状”。(14).A. help B. saveC. carry D. prevent（分数：3.50）A.B. C.D.解析：动词辨析。由转折连词 but 可知，此句是对上文的转折。上文说火星上任何的地表水都是以冰的形式存在的。结合“_explorers having to take so much fresh _ with them”可以推断，but 后说的应该是“探测者们不必带太多新鲜的水”，故此处应选 save(节省)，save sb(from) doing sth意为“省去(某人的)劳力”。(15).A. water B. iceC. food D. vegetable（分数：3.50

48、）A. B.C.D.解析：名词辨析。由 80 题解析可知，此处应该选 water。ice 不与 fresh 搭配，且与文意不符。C 和 D 在文中没有相关信息支持。(16).A. what B. ifC. how D. that（分数：3.50）A.B.C.D. 解析：连词辨析。通过分析句子结构可知，say 后接宾语从句，故选 that。what 不是从属连词；if 引导宾语从句时，前面的动词一般是 ask，doubt，dont know，不用 say；how 一般引导主语从句。(17).A. pass B. pastC. ago D. before（分数：3.50）A.B. C.D.解析：形

49、容词辨析。固定搭配 in ages/time past(很久以前，在过去)。(18).A. Not B. NoC. Nor D. Never（分数：3.50）A.B. C.D.解析：词义辨析。此空格处应填 no，no 可以放在单数及复数名词前，也可放在句首。not 放在可数名词前；nor 是连词，常与 neither 连用，不能作定语修饰名词；never 作副词放在句首时，句子应倒装。(19).A. detected B. touchedC. seen D. felt（分数：3.50）A. B.C.D.解析：动词辨析。空格所在的分句是被动语态，意为：在火星上，软着陆的仪器没有_令人信服的生命存在的迹象，故选 detect(发现，察觉)。(20).A. probably B. perhapsC. supposed D. although（分数：3.50）A.B.C.D. 解析：词义辨析。通过分析句子结构可知，空格处需要填入连词来连接前后两个分句，所以可以首先排除A 和 B。空格所在的分句意为：只有登陆车附近的区域可以检查，说明前半句得出的结论是有前提条件的，所以此处应选 although 引导让步状语
