Most worthwhile careers require some kind of specialized training. Ideally, therefore, the choice of an (1) should be made even before choice of a curriculum in high school. Actually, (2) , most people make several job choices during their working lives, (3) because of economic and industrial changes and partly to improve their position.

Unfortunately many young people have to make career plans (8) benefit of help from a(n) (9) vocational counselor or psychologist. Knowing (10) about the occupational world, or themselves for that matter, they choose their lifework on a hit-or-miss basis. Some (11) from job to job. Others (12) to work in which they are unhappy and for which they are not fitted. One common mistake is choosing an occupation for (13) real or imagined prestige. Too many high school students-or their parents for them-choose the professional field, (14) both the relatively small proportion of workers in the professions and the extremely high educational and personal (15) .The imagined or real prestige of a profession 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.1.

C介词辨析。本句讲年轻人的职业规划，根据本句第一个单词unfortunately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。9A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”；effective意为“有效率的”。10A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。11B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drift。drift from work to work意为“不停换工作”。12. C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)。13B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. D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)。15B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)，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”。16C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”。17D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。18C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”。19A名词辨析。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。20C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”。强化训练二Directions: There are 20 blanks in the following passage. For each blank there are four choices marked A, B, C and D on the right side of the paper. You should choose the ONE that best fits into the passage, Then mark the corresponding letter on Answer Sheet 2 with a single line through the centre. The horse and carriage is a thing of past, but love and marriage axe still with us and still closely interrelated. Most American marriages, (1) first marriage uniting young people, are the result of mutual attraction and affection (2) than practical considerations. In the United States, parents do not (3) marriages for their children. Teenagers begin (4) in high school and usually find mates through their own academic and social (5) . Though young people feel free to choose their friends from (6) groups, most choose a mate of similar (7) . This is due in part to parental guidance. Parents cannot (8) spouses (配偶) for their children, but they can usually (9) choices by voicing disapproval of someone they consider unsuitable. (10) , marriages between members of different groups (interclass, interfaith, and interracial marriages) are (11) , probably because of the greater mobility of todays youth and the fact that they are (12) by fewer prejudices than their parents. Many young people leave their hometowns to attend college, serve in the armed forces, (13) pursue a career in a bigger city. Once away from home and family, they are more (14) to date and many outside their own social group. In mobile American society, interclass marriages are neither (15) nor astonishing. Interfaith marriages are (16) the rise, especially between Protestants(基督教徒) and Catholics(天主教徒). On the other hand, interracial marriages are still very (17) . It can be difficult for interracial couples to find a place to live, maintain friendships, and (18) a family. Marriages between people of different national (19) (but the same race and religion) have been commonplace here (20) . colonial times.1. A specially B naturally C particularlyD fortunately2.

A source B convention C origin D immigrant20. A since B with C by D during 试题详解1C副词辨析。first marriage uniting young people是most American marriage中的一部分，由此可以作者在这里是以前者为例，particularly(尤其)多用于举例。specially意为“特别地”，多用于表示不普通、不寻常的特点。naturally(自然地)和fortunately(幸运地)与文意相差太远，可以首先排除。2B 固定搭配。空格所在的句子讲的是美国人结婚的原因，practical consideration(现实的考虑)与mutual attraction and affection(互相吸引和爱慕)在广义上是一种对比关系，所以应该选rather，rather than是固定搭配，表示“而不是”，相当于instead of。3A动词辨析。本句的意思是：在美国，父母不_子女的婚姻，根据常识应该选arrange，arrange marriage意为“包办婚姻”。engage(订婚)和 propose(求婚)不能与marriage搭配；manage(经营)与原文不符。4B 动词辨析。由and usually find mates可知，空格处应该填入与“交友”有关的词，故选dating(约会，特指异性间)。appointing指用权力或共同约定来决定或安排，不合题意。5D名词辨析。through their own academic and social_是美国中学生交友的途径故选contact(接触，交往)。positions意为“地位”，associations意为“联系”，contracts意为“合同”，均不符合文意。6. D形容词辨析。空格所在分句的句首出现转折连词though，所以前后分句为转折关系。根据后一句中出现的similar可以推断空格处应该填入一个与之意义相反的词汇，故选different。separate意为“分开的”，identical意为“相同的，同一的|”，independent意为“独立的”。7A 名词辨析。根据前半句可知，大多数美国年轻人不会选择与自己来自不同 groups的人，即两个人要有相似的background(背景)。situation意为“情况，情形”，circumstance意为“环境”，condition意为“条件”。8C 固定搭配。由上文可知，美国年轻人选择和自己背景相似的人，部分的原因是父母的引导。本句说“父母不会但是会”，根据常识，父母应该不会为子女选择配偶，故答案为select，selectfor是固定搭配，意为“为选择”。object(协)意为“反对”；reject意为“拒绝”，不能和for搭配；approve(of)意为“同意”。9A动词辨析。由转折词but可知，本句和前半句“不能为孩子选择配偶”应为转折关系，故选influence(影响)。10B副词辨析。上文讲年轻人喜欢找背景相同的配偶，但下文讲的是不同阶级、信仰、种族之间的婚姻，可见前后是转折关系，故选however(然而)。 therefore意为“因此”，表因果关系；moreover童为“此外”，表递进关系； likewise意为“同样地”，表对比关系。11C 动词辨析。由空格后的the greater mobility of todays youth(如今年轻人更大的流动性)和_by fewer prejudices than their parents(比他们的父母更少受到歧视的_)可知，不同groups之间的婚姻应该是逐渐增加的，故选increasing。declining意为“下降”；prohibiting意为“禁止”；reducing“减少”，都不符合文意。12D动词辨析。此句意为：年轻人比他们的父母受到更少歧视的，结合上文应选restricted(限制)。respected意为“尊敬”；retain意为“保持”；reserve意为“预订”。13B 逻辑关系。根据上下文逻辑关系，前文的求学(attend college)、参军(serve in the armed forces)与空格后的创业(pursue a career)应是并列关系，故选 or。14A形容词辨析。根据上下文逻辑关系，离开家乡和家庭(home and family)之后，年轻人与其他社会群体的人约会及结婚的可能性应该是增加了，故选 likely，be likely to意为“可能”。possible也意为“可能”，但不用这个结构，且表示的可能性较小；be reluctant to意为“勉强”；be eager to意为“渴望”。15C 形容同辨析。此句意为：在美国，不同阶级之间的婚姻既不_，也不奇怪，or连接的是并列结构，故空格处应该填入astonishing的近义词rare (稀少的)。scarce意为“不足的”；risky意为“冒险的”；rigid意为“严格的”。16D 固定搭配。on the rise意为“不断上升”，表上升趋势。17B 形容词辨析。由句首的on the other hand(另一方面)可知，此处应是转折关系，故处应该填入与on the rise相反或相对的词答案是uncommon(不寻常的)。18A固定搭配。raise a family意为“养家”。19C名词辨析。根据括号中的解释，这种婚姻的双方种族和信仰相同，但来自不同国家，故选origin(出身)。source意为“(信息等的)来源”，convention意为“习俗”，是干扰项，相同种族和信仰的人习俗应相同，故可以排除； immigrant意为“移民”，也是干扰项，可数名词应使用复数形式。20A介词辨析。空格所在句子为完成时态，而colonial times表示的是一个时间起点，故选since(自从)。强化训练三Directions: There are 20 blanks in the following passage. For each blank there are four choices marked A, B, C and D on the right side of the paper. You should choose the ONE that best fits into the passage. Then mark the corresponding letter on Answer Sheet 2 with a single line through the centre. Mars is not, it seems, the dry old planet we 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 pictures 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 torrential 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 fresh (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 could be examined.1.

A detected B touched C seen D felt20. A probably B perhaps C supposed D although试题详解1A 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。2B 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。3A 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”，侧重指做某事的条件或时机。4C 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。5B 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”。6D 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。7D名词辨析。由于and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。8C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lifeless(死气沉沉的，没有生命的)。9A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。10D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“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。11C 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)。12A 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”。13C 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，形状”。14B 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”。15A 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。16D 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。17B 形容词辨析。固定搭配in ages/time past(很久以前，在过去)。18B 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。19A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)。20D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引导让步状语从句。suppose表假设引导句子时，后面需加that。强化训练四Directions: There are 20 blanks in the following passage.
