A、Workingwomenwhohavenotimeforcooking.

Husbandsandchildrenofworkingwomen.

C、Workingwomenwhomusttravelontheirown.

D、Hotelpersonnelwhomustattendtoworkingwomen.

标准答案：C-

知识点解析：推理题。纵观四个选项，出现最多的就是workingwomen,短文无疑

与workingwomen相关。录音第一句women...totheprofessionalladder验证了这个

推断，接着提出了文章主题makebusinesstripsalone,因此文章探讨的是职业女性

单独出差的话题。

28、

B、Itiseasytoremove.

C、Ilcandoubleasabriefcase.

D、Itisusuallybigenoughtocarryallbusinessdocuments.

标准答案：B

知识点解析：细节题。这里的“指代不明，就需要仔细听问题了。当然从四个选项

中还是可以看出it与行李、箱子相关。本题关键是听清问题问的是轻便的行李

lightweightluggage为什么对出差的女士来说很重要。回忆所听内容，lightweight

luggage之后说youcaneasilymanage。

29、

A、Inamagazinespeciallyforwomen.

B>Inarestaurantandhotelguide.

C^Inanewsmagazine.

D^Inajournalfortop-rankingbusinessmenandwomen.

标准答案：A

景。文章开头就表明对象是众位职业女性，接着针对她们单独出差提供了一些建

议，包括饮食、行李等方面（Ifyou…Ifyou…Finally表明了这种层次关系），因比本

文最可能出现在女性杂志上。

3。、

A、Intheearly1880s.

B、Severaldecades.

C、In1861.

D、In1865.

标准答案：D

知识点解析:题目问战争结束的时间，文中提到“Whenthewarbeganin1861,most

Americansbelievedtheconflictwouldnotlastlong.Instead,itstretchedintofour

yearsofbloodyfighK战争是1861年爆发的，大部分美国人都觉得不会持续太久

的。但是没想到血腥的战争持续了四年之久）“，可见结束时间是1865年。

31、

BNThefactthattheNorthhadmorepoliticalpowerinSenate.

C、Taxes.

D、DifferentpoliticalpowerintheHouseofRepresentative.

标准答案：B

知识点解析：题目问四个选项中哪个不是南北的分歧所在。原文提到南北的分歧主

要有五个方面：slavery,tariffs,taxes,politicalpowerintheHouseof

Representative,andthepoliticalpowerintheSenateo显然B）中的信息没有提到。

32、

A、Becausetheydeededworkerstoraisecottonandtobacco.

B、Becausetheythoughtslaveryeconomyinhumane.

C、Becausetheywantedtounitetheircountry.

D、Becausetheirpillareconomyaskedformorelaborforces.

标准答案：D

opposedslaveryintheSouthsincetheyhadnotenoughpeopletoworkintheirfactories

48、[Si]

标准答案：C

知识点解析：此处应为名词。名词词库中，只有help可构成withihehelpof用法，

表示“在……的帮助下”，符合语义。

49、[S2]

标准答案：J

知识点解析：此处应为形容词，作表语。下文讲的都是有关试管婴儿的健康问题，

据此可知此处是讲专家关心这类小孩是否健康，healthy符合文意。

50、[S3]

标准答案：L

知识点解析：此处应为形容词，修饰armsorheads。由上文justfine“还好”可知此

处是说手臂或者头是正常的。由空前的notlike可知此处应为贬义，填入extra表示

“多手臂或多头的小孩”，符合语义。

51、[S4]

标准答案：M

知识点解析：此处应为名词。上文说到“没人年龄超过30来岁”，据此可知此处应

该表达“大部分在20岁以下”，ihevaslmajority是常见表达，表示“绝大多数”，符

合语义，故选majorityo

52、[S5]

标准答案：A

知识点解析：此处应为动词。根据空后的2.5kilograms可知此处为“重”之义，

weigh符合。

53、[S6]

标准答案：F

知识点解析：此处应为副词，修饰conceived。此空所在句用morelikely…than…表

比较，从语义上看，与ihroughlVF(通过体外受精而怀孕)作比较的应该是“自然怀

孕”，不难选择naturallyo

54、[S7]

标准答案：G

知识点解析：are后面要接动词过去分）司形式表被动，在宾语从句中作谓语动词。

下文出现的gene-expression很好地提示此处应选expressedo

55、[S8]

标准答案：B

知识点解析：此处应为名词。根据文意，被用来产出试管婴儿的应该是一项技术

（即体外受孕技术）。technology符合此意。

56、[S9]

标准答案：E

知识点解析：此处应为形容词，作表语。空后的whether表明不确定性，词库中

unsure和unclear都含有“不确定”之义，但是unsure的主语一般为人，unclear的主

语一般为物，根据句子的主语It可知应选unclear。

57、[S10]

标准答案：I

知识点解析：此处应为形容词。上文提到各种不确定因素，此空所在句句首用But

表转折，说明由体外受精生出的小孩在某种程度上是“独一无二的“，选unique。
