身体健康的人不愿意去想死亡的事，死亡是我们希望避免的话题。但是死亡是普遍的人生经历，是人人都要面临的少数必然之一。理智的人对必然的死亡预作计划，从容对待；只有愚蠢的人不能正视现实，希望用某种方法逃脱死亡。人寿保险对必然的死亡提供理智的安排。只要对自己的死亡能够直面对待的人才能充分理解人寿保险的必要性。人寿保险公司充分认识到了人民对死亡的负面印象，为此，他们对保险代理商进行培训时，要求他们在推销中避免使用直率的语言，而努力以恰当的方式让客户们意识到：人终究会死，人人都会面临死亡，必须要客观地接受自己的比如死亡才能在经济上为此做好充分的准备。

FreshWater.YoushouldbaseyourcompositionontheoutlinegiveninChinesebelow

：1.人们认为淡水是取之不尽的

;2.实际上淡水是短缺的;3.我们应当怎么办。

参考答案

1.A

2.A【句子大意】新打字机的价格是二手货的三倍。

3.A

4.C

5.D

6.C解析：本题考查倒装虚拟语气用法。本句是表示与将来事实相反，所以从句用wereto形式。句意为：如果他今天出发的话，他就会在星期五以前到达那里。

7.B解析：此处是对将来情况的假设。虚拟条件句的谓语部分为should，had或were时，可把if省去，而把should，had或were放在从句的主语之前，构成主谓部分倒装。

8.D

9.A解析：反问疑问句的陈述部分是肯定式时，疑问部分用否定式。以letme或letus起始的反问疑问句，疑问部分用willyou或won'tyou，所以选项A是正确的。

10.C解析：本题考查词义的辨别。rise出现，put放下，raise提起，arise升高。

11.B解析：表示否定的副词前置于句首，句子需要不完全倒装，即助动词提前。其余选项均可排除。除Notuntil外还有never，seldom，rarely，seldom，no，little，hardly，innotime等否定副词或结构放在句首时，句子需要部分倒装。

12.D

13.A

14.D解析：从句中的问句主谓不倒装。从句的时态随主句。我想知道那辆车的价格。

15.A解析：根据上文提到“findone”，故下文中也应填one，表示泛指。

16.B解析：takemeasures意思为“采取措施”，本句应用被动语态。

17.B

18.A解析：while意为“虽然”；as意为“因为”；if意为“如果”；since意为“因为”。根据题意选A。

19.B解析：encourage：鼓励、鼓舞；discourage：使泄气；prevent：阻止；ask：要求。根据句意只有选B。

20.D解析：本题测试形容词辨析。四个选项的意思分别是“普通的”，“清楚的”，“正义的”，“仅仅的”。根据句意，D项正确。本句大意为：他仅仅把它作为一个细节来描述，而我却认为它是这个计划中最重要的部分。

21.就这一问题曾做过大量的研究，其结果揭示出这样一个答案:我们是通过一种特殊的平均化方式来形成第一印象的。

22.甚至在毕业后年轻人发现自己又被飞涨的房价所束缚。甚至在毕业后，年轻人发现自己又被飞涨的房价所束缚。

37.Ⅵ．Writing2006年末最新颁布的《全国各类成人高等学校招生复习考试大纲(专科起点升本科)》对英语短文写作(第六部分)的要求为：一个小题，满分25分，要求考生根据所给题目或提出的条件(即情景)写出一篇100～120问的短文。同时还要求，在短文写作中，要考虑“文章的特定文体格式”。“根据所给题目或提出的条件”可意指英语命题作文写作，通常以论说文、说明文写作格式为主，内容一般涉及公众关注的话题；还可意指英语信函、便条写作，通常以英语信函写作中常用的“混合式”格式为主，内容一般涉及人们日常生活中的交往问题新大纲指的是后者。在具体短文写作时考生应注意以下方面：(1)避免使用“过分”词句，语言要简明扼要有些英语初学者会觉得，在英语短文写作中，使用的“大问”越多，水平就越高，这是一种不正确的看法，因为这会在英语短文写作中导致“过分”用词的问题。考生作文在内容上要能够做到紧扣命题或情景，应采取语言简明扼要的行文方式。下面列出一些在写作时提倡和不提倡使用的词语：括弧中的词语为提倡使用的词语

括弧中的词语为提倡使用的词语inregardto(about,concerning)

withregardto(about,concerning,on)inrelationto(toward,to)

inconnectionwith(about,of,in,on)onthepartof(for,among)

withreferenceto(on,about,concerning)inviewof(because,since)

intheeventof(if)inorderto(to)

onbehalfof(for)inaccordancewith(with,by)

bymeansof(with,by)inthecaseof(if,in)

inthematterof(in)intheamountof(for)

forthepurposeof(for)inthemajorityofinstances(usually)

inanumberofcases(some)onafewoccasions(occasionally)

inthetimeof(during)(2)不使用缩写形式等过于口语化的字词①一般不应使用缩写形式，如：不应使用"itdidn't”，而应使用“itdidnot”；不应使用"they've”，而应使用"theyhave"等。②一般不应使用表示犹豫不决的短语，如：er，um，well，youknow...，andsoonsoforth，andetc．等(3)避免中文式的“铺垫”“铺垫”、“迂回”或“画龙点睛”等写作方法在中文短文写作中无可非议，但不能使用在英语短文写作中。例如，中文信件的开头方式通常会是“你好!前日收到你的来信，深感欣慰。好久没有给你写信了。不知你的……如何?”等，此类句式不应在英语信函短文写作开头处使用。原因是，此种方式会浪费篇幅。考试中英语短文写作有字数限制，写得太长同样会被扣分。在进行信函短文写作时，考生应注意以下方面：(1)短文写作情景分析中文情景写作中需要直接表述和需要拓展表达的内容。(2)确定信函短文写作的谋篇布局信函短文写作的谋篇布局的含义为信函写作格式。信函短文写作采用的是英语信函写作中的“混合式”。(3)进行语言转换和拓展(4)信函短文合成61．参考范文DearClubManager,
