who

areB.for,

which

wasC.to,

which

areD.to,

who

were复合句答案1：D:who试题解析：非限定性定语从句，不能用that，而用who。2：D:when

we

went

there试题解析：宾语从句用陈述句语序。A项中有by

bus就不能用how。

3：B:Whether试题解析：whether表示“是否”之意，引导主语从句时，不用if引导。4：C:until试题解析：until既可用于肯定结构，也可用于否定结构。肯定结构意为“到……为止”；否定结构意为“直到……才”。本题主句谓语动词为终止性动词，用了否定句，应译成“直到我回来，我才给你打电话。”5：D:shook

hands

with试题解析：shakehandswithsb是一个有用的短语,意为"和……握手"。6：B:where试题解析：答案：B解析：此题考查的是定语从句的用法。分析句子结构可知，该空所填词要引导定语从句，由此可以排除A，因为what不可以引导定语从句；因从句的基本结构主谓宾齐全，所以使用关系副词引导定语从句，且在从句中作状语。故正确答案唯有B项。7：A:

What试题解析：答案解析:名词性关系代词what引导的主语从句，在此处what

=

the

thing

which

。8：B:whatever试题解析：whatever引导名词性从句，作宾语，意为“无论什么……都”。9：C:I

have

been试题解析：先行词是time,

day,

month,

year等名词时，其定语从句用when引导，但It’s

the

first

(secod,

third)

time

that….是特殊结构，只能用that引导，可以省略。这里的that=

when。故选C。10：A:even

if试题解析：even

if“即使”，引导让步状语从句。此句表示“即使第二天有重要的考试，他也不会离开电视机”。11：A:where试题解析：where引导宾语从句，在从句中作地点状语。12：D:whose试题解析：从句是

________

purse

was

lost，purse是可数名词，前面应有修饰词，该词在句中又要起连接主从句的作用，故用whose。在此句中，whose

purse

也可以写成the

purse

of

whom.13：B:until

试题解析：when和after在此同义，用在此处都不合逻辑。用since则时态不对。14：B:unless试题解析：考查连词的用法。Unless意为“除非，如果不”，引导条件状语从句。15：D:that试题解析：此题考查同位语从句，no

doubt表确定含义应用that引导。16：D:before试题解析：一段时间+before…过了（多少时间）才……；It一段时间+before…没过（多少时间）就……

此句型只使用过去时或将来时。例如：

ItwasalongtimebeforeIgottosleepagain.过了很长时间我才再睡着。

Itwon'tbelongbeforehecomesback.他要不了很长时间就会回来。

Itis+一段时间+since…（过去时）……自……以来（有多少时间）

ItisthreeyearssinceshejoinedtheParty.她入党已有三年了。17：A:to

be

honest

试题解析：consider

the

boy

to

be

honest；句中the

boy为先行词。"I

considered

_____"为定语从句。

18：C:that

试题解析：答案：C解析：此题考查定语从句。因worried

about后要接宾语，所以此处使用关系代词引导定语从句，由此可以排除D；what不可以引导定语从句，所以排除B；当先行词为不定代词everything时，只能使用that引导定语从句。19：B:that试题解析：doubt

+

wh-从句；not

doubt

+

that-从句20：B:While

they

were

golfing试题解析：这里由于从句谓语动词golf的逻辑主语并不是主句的主语a

rabbit，因而此类省略不发生，整个句子应该有一个完整的时间状语从句。21：D:As；which试题解析：该题考查非限制性定语从句。what不能引导定语从句，that不能引导非限制性定语从句。as和which都可以引导非限制性定语从句。which可代替前面句子的整个或部分内容；as表示"与……一致；正如"之意，可代替前面或后面句子的整个或部分内容，常用于as

we

know／see，as

we

expected等短语中。as可放在句首或句子中，which只能在句中。故答案应选D。22：B:Whether试题解析：Whether与or

not连用，引导让步状语从句。23：A:such

fine

weather

试题解析：weather[U]n.虽然前面有adj.修饰，也不能加a/an,只能用“such+adj.+[U]n.”结构。24：A:what

试题解析：what在表语从句中作takes的宾语，构成“Ittakessth.todosth”的句型。25：C:whoever

试题解析：从句子结构上分析，主句中的介词“to”后缺少宾语，而从句也没有主语，这时肯定要填上一个具有“双重功能”的关系性wh-连词。who和whom无此功能，排除之。D项的whomever，在这里也不对，故选C。26：C:incase试题解析：本题考查从属连词。由信息句John

may

phone

tonight

(约翰可能今晚给我打电话)，可知“我不想出去”，是怕“万一他给我打电话。”as

long

as意为只要,

in

order

that…表示目的。27：B:being

discussed；surprising

试题解析：being

discussed作后置定语，修饰the

problems。sth.

is

surprising。28：C:as试题解析：选C。先行词前若有so/such/the

same等词时其关系词应用as。29：C:when试题解析：when引导的从句修饰day，为了平衡后置。30：C:what

试题解析：what引导的从句作from的宾语。这里的what相当于the

book(the

One

which／that／省略关系代词)。31：C:

as

though试题解析：asif/asthough好像……一样似的。引导表语从句或方式状语从句。若从句所述情况与事实相符，用陈述语气。若从句所述情况与事实不符或相反，则用虚拟语气，不管什么人称be通常用were,但第一、三人称单数主语有时也用was。在look,seem,taste,smell等动词后的asif/though从句中用陈述语气的情况也不少见。Shefeltasif/thoughHarrietwereamemberofherownfamily.（表语从句；虚拟语气）Helooksasifhewerefromthecountry.（表语从句；虚拟语气）Itseemsasifweshallhavetowalk.（表语从句；陈述语气）表示“看起来好像……”的句式有：Itlookasif．．．;Itseemsthat/asif．．．;Itappearsthat/asif．．．32：D:that试题解析：注意best是最高级，其后的定语从句只能用that。如that作为从句中的宾语也可以省略。此题中that可省略。33：D:where试题解析：选D。先行词是cases，“情况”，where引导定语从句，作状语，相当于in

which。34：A:that试题解析：that为关系代词，引导定语从句，并在从句中作宾语。35：C:that

试题解析：这是一个先行词为the

way的定语从句。定语从句原来的完整句子应是：he

treats

his

mother

in

the

way，所以定语从句可以用in

which引导。但在现代英语中，也可以用that或省略

that的形式。36：B:That

试题解析：分析题意可知,“时髦因国家不同而不同”表述的是事实，所以要用引导词that引导表语从句。37：A:So

far

as试题解析：C项只能引导主语从句和宾语从句。答案为A。38：B:that

试题解析：that引导同位语从句，作thought的同位语。39：C:in

case试题解析：引导条件状语从句的连词as

long

as不合题意。In

order

that和so

that都可以引导目的的状语从句，但它们不同于in

case引导的目的状语从句，in

case状语从句含有可能性的意义，可译作“万一”、“以防”。由句子意思可知，最佳答案为

C。40：A:whatever试题解析：do后接宾语从句：宾语从句I

can后省略了do，缺少宾语：whatever在宾语从句中作宾语。41：C:Whenever试题解析：选C。whenever意为“每当，无论何时”，等于no

matter

when。42：A:that

试题解析：此题考查shame的用法。a

shame意为a

pity，表示“令人遗憾的事；令人惋惜的事”。通常跟that引导的从句。如：It’s

a

shame

that

you

are

1ate

again．What

a

shame

that

you

are

late

again．还可以跟不定式。如：It

is

a

shame

for

you

to

be

late

again．43：B:whether试题解析：由语境可知该空引导从句，表示“是否”，因此应填whether而不能填if。44：D:so

fast

as试题解析：这里是比较状语从句，as…as和not

so…as中间只能接形容词和副词的原级。45：A:why试题解析：本题考查宾语从句的引导词。根据语句的意义，选A比较恰当。句子意思是：路面上覆盖满了雪，我不明白他们为什么坚持要骑摩托车。46：D:who

it

is试题解析：宾语从句要用陈述句的语序。如果我们对所谈到的那个人还不清楚是谁时，要用it。47：C:the

first

time

试题解析：the

first

time(第一次)和every

time，by

the

time，last

time都可以引导时间状语从句。句意为：我第一次和她见面时，就认为她很诚实。48：A:where试题解析：where引导的定语从句，相当于in

the

situation。49：B:what

was

the

matter试题解析：what

was

the

matter(with)和what

was

wrong(with)作宾语从句时语序不变。注意what

was

the

mater和what

the

matter

was含义不同，后者意为“这是什么物质”。50：A:the

ones试题解析：后面出现定语从句修饰，表示拿课本的“那些学生”显然是特指概念，因此排除B和C。the

others“其余的人或物”，本身已表示是范围中的另一部分，后而不能用定语从句修饰。51：B:Whatever试题解析：whatever

引导名词性从句，并在从句中作定语，修饰measures,

意为“任何……的……”。52：D:Since,

who

do

you

think试题解析：since引导原因状语从句，意为“因为、既然”；特殊疑问句作do

you

think的宾语从句时，疑问词要放在

do

you

think前面。53：D:where试题解析：where引导定语从句，相当于in

which，即in

the

situation。54：B:what

试题解析：根据第二句的回答，“有人说他是一名推销员”。这是指职业，用what可以指职业，其余均不能。55：A:that试题解析：先行词被the

only,

the

same,

the

last修饰时，只能用that引导定语从句。56：D:All

the

three试题解析：无论根据语法和句意，A、B、C各项都成立。57：B:what试题解析：宾语从句中动词do缺宾语，只有what可作宾语。58：D:such

a试题解析：It

is/

seems

a

pity

that．．．(好像)遗憾……；such

a

+

可数名词单数。59：D:where试题解析：从句缺少状语。60：C:which试题解析：选C。which引导的非限制性定语从句，that不可引导非限制性定语从句。61：D:when试题解析：此题考查时间状语从句中连词的选用。题中所给选项C不引导状语从句。选项A、B、D均能引导时间状语从句，都表示“当…时候”，但它们的用法和含义各有不同。1)当主句的谓语动词表示短暂时间的动作，而从句的动作可以持续一段时间时，三个连词都可以用。2)主从句的谓语动词为非持续性，而且两个动作几乎可以同时发生时，不用while，可用when或as．3)从句的动作在主句的动作之前时，只用when．4)主句用进行时态，从句的动作发生的时间只是其中的一个时间点时，只用when．5)主从句的动作都在一段时间中发生时，可用while．如：6)表示“一边…，一边…”时，用as或while．此题中主句用的进行时，从句“I

ran

into

Mr.

Wilson”只是在“来的途中”发生的一个动作，所以应用when，此处的when相当于at

this

time．62：C:where

试题解析：business此处意为“公司、企业”，是表示地点的名词，故须用关系副词where引导定语从句，且在从句中作状语，可换成in

which。63：C:

that

试题解析：that引导的从句作介词except的宾语。其余三个选项语意不符。64：B:supposed试题解析：本题是省略的比较从句，完整的句子是…than

they

are

commonly

supposeD.故选B。65：C:where试题解析：先行词是地点名词，定语从句中又缺地点状语，用关系副词where。66：D:which试题解析：关系代词which可以引导非限制性定语从句，并充当其中的主语或宾语，其先行词可以是整个主句，也可以是主句的一部分。本句中which代替的是前面一整句话的内容。67：A:

in

case试题解析：in

case(以防)表目的，so

that(以便)表结果；although(虽然)表让步；if(如果)表条件。68：D:which试题解析：does

it

matter．．．中的it是形式主语，which(哪一)引导主语从句。69：B:the

moment试题解析：the

moment(=as

soon

as)一……就……。另外，从句中的谓语动词saw是非延续性动词，不可用while引导。70：A:that试题解析：在此主语从句中，各个成分均已“客满”，没有what或which的位置。如果doing后没it一词，可以选用what或which，它们便可以作doing的宾语。that在此处不可省略。71：B:As

试题解析：as在开头引导非限制性定语从句。72：C:which试题解析：本题选C正确。如果选A，find后应有it作宾语，impossible作宾语补足语。而选C的理由是，which引导非限制性定语从句，which在从句中作find的宾语，which指代前面句子：I’mtryingtogetoutofthe…。73：A:What；what

试题解析：从语法项目分类看，此题涉及的是两个名词从句，都是主语从句，其基本框架是What

we…seems

better

than

what

we…。此题把两个简单的主语从句用seem相连，加上使用了比较级，就构成了识别语句基本框架的难度，使得简单句式复杂化。74：C:based

on

试题解析：according

to

在作“根据，依据”讲时只做状语，不做表语。According

as是较正式用语，意为“根据，取决于，视……而定”，是从属连词，后接从句。如：You

may

go

or

stay,

according

as

you

decide.是去是留由你自己决定。Depend

on是“依靠，依赖”。Be

based

on/

upon是“以……为基础”，符合题意。故正确答案为C。75：B:so

that

they

could

试题解析：so

that此处表目的。76：A:since试题解析：当表示已经知道的原因时用as

或since,

但since比

as正式一些.77：B:whom
