毛毛zwt

一、特殊并列連詞while\when
【例1】I had just stepped out of the bathroom and was busily drying myself with a towel____ I heard the steps.
A.while B.when  C.since D.after
【例2】I’d like to study law at universitymy____ cousin prefers geography.
A.though  B.as  C.while  D.for
【答案與解析】BC。作并列連詞時,when\while用法較為特殊,二者區別是:while表兩相對照;而when表突然、在那時,常見于be about to do...when和Hardly...when等句型中。
二、表示原因的連詞for\because\as\since
【例3】He found it increasingly difficult to read,____his eyesight was beginning to fail.
A.and B.forC.butD.or
【例4】Jenny was very sad over the loss of the photos she had shot at Canada,____this was a memory she especially treasured.
A.asB.ifC.whenD.where
【例5】 Parents should take seriously their children’s requests for sunglasses_____eye protection is necessary in sunny weather.
A.becauseB.thoughC.unlessD.if
【例6】_____everybody knows about it,I don’t want to talk any more.
A.ForB.EvenC.SinceD.However
【答案與解析】BAAC。引導原因狀語從句,as\because\since\for的區別是:because語勢最強,用來說明人所未知的原因,回答why提出的問題,可置于強調句中且其前可加修飾語;since是雙方都知曉原因或經過分析而得之的原因,語氣次之;for是并列連詞,前用逗號隔開,表邏輯推理或補充說明;as語氣最弱,原因是顯而易見的或已為人們所知,即已知原因,所引導的分句可置于句首。
三、并列連詞but\yet\though
【例7】Excuse me for breaking in,______I have some news for you.
A.so B.and C.but D.yet
【答案與解析】C。but和yet是連詞,可等同使用,但也有區別。yet與and連用,構成and yet,但but卻無此用法;在“Excuse me\I’m sorry\I hope you don’t mind…but’’中,只用but,不用yet。因為在表示對照或對立時,but較為輕松自然;而yet卻較為強烈,常出人意料;though作并列連詞時,只能引導分句且其前須加逗號。例:
I’ll try to come,though I don’t think I shall manage it.
四、引導名詞性從句的從屬連詞that\whether\if
【例8】The traditional view is_____we sleep because our brain is “programmed” to make us do so.
A.whenB.whyC.whetherD.that
【例9】We haven’t settled the question of______ it is necessary for him to study abroad.
A.if B.where C.whetherD.that
【答案與解析】DC。引導名詞性從句的從屬連詞that與whether的區別是:句子成分完整且表意確定時選用that連接,句意不確定時選用whether\if連接;借助it,將真正主語或賓語后置,構成“It…that”句型,但whether\if不可;下列情形用whether不用if:與or not連用,中間無其他詞隔開;作介詞賓語;在主語從句、表語從句和同位語從句中。例
Whetherwe’ll go camping tomorrow depends on the weather.
五、表示比較的從屬連詞what\as
【例10】Engines are to machines______hearts are to animals.
A.asB.that C.whatD.which
【例11】______I explained on the phone,your request will be considered at the next meeting.
A.WhenB.AfterC.AsD.Since
【例12】What a table! I’ve never seen such a thing before.It is______it is long.
A.half not as wide as B.wide not as half as
C. not half as wide as D.as wide as not half
【答案與解析】CCC。what用作從屬連詞,表比較,用于A is to B what C is to D結構中;而as表示原級比較,常用于as…as結構中,程度修飾語應置于第一個as之前,嵌入的形容詞或副詞使用原級。另外還表“正如、按照”,引導方式狀語從句。
六、表示條件的從屬連詞if\unless\as long as\once
【例13】______I know the money is safe,I shall not worry about it.
A.Even though B.Unless C.As long as D.While
【例14】Small sailboats can easily turn over in the water_______they are not managed carefully.
A.thoughB.beforeC.untilD. if
【例15】You will be successful in the interview___ you have confidence.
A.beforeB.onceC.untilD.though
【例16】I won’t call you,_____something unexpected happens.
A.unlessB.whetherC.becauseD.while
【答案與解析】CDBA。表條件的連詞if\unless\as long as\once在用法上存在一些差異。as long as用法同only if\on condition that,強調某事的發生以另一事件的發生為前提;if為正面條件,可能會產生好的或壞的結果,若某種條件產生壞的結果,此時的if可用as long as替換;unless為反面條件,表示除非,如果不,故在真實條件句中常和if…not換用;once既表時間,又包含條件,譯作一旦。
七、表示讓步的從屬連詞although\when\while
【例17】We had to wait half an hour ___ we had already booked a table.A.sinceB.although C. until D.before
【例18】______I really don’t like art,I find his work impressive.
A.As  B.Since  C.If  D.While
【答案與解析】BD。although\when\while均可表示讓步,后兩者的用法較為特殊。although/though引導讓步狀語從句時不與but和yet連用;而while卻表示“部分接受,但并非全部”,或用于“強調兩種情況、活動等之間的差距”;when也可表示雖然,盡管,同even if,常置于句末。例:
(1)While I accept that he is not perfect,I do actually like the person.
(2)He walks when he might take a taxi.
if用作從屬連詞,也可表讓步,類似though,用以描述自己喜愛的人或物。如:He’s a pleasant child,if a little spoiled.
八、從屬連詞so that\in case
【例19】I’d like to arrive 20 minutes early______I can have time for a cup of tea.
A.as soon as B.as a result  C.in caseD.so that
【例20】Leave your key with a neighbor____you lock yourself out one day.
A.ever sinceB.even if C.sooner after D.in case
【答案與解析】DD。so that既表示結果又表示目的。若置于主句后,用逗號隔開常表結果;與情態動詞連用常表目的。in case表示假設,譯作“萬一”。例:
I always take something to read when I go to the doctor’s in case I have to wait.
九、關聯連詞so/such…that
【例21】Pop music is such an important part of society________it has even influenced our language.
A.as B.thatC.whichD.where
【例22】_______homework did we have to do that we had no time to take a rest.
A.So muchB.Too much C.Too littleD.So little
【答案與解析】BA。關聯連詞so/such…that(如此……以致),只表結果,置于句首時,主句要部分倒裝;so為副詞,后續形容詞或副詞。such后續名詞,名詞前可接限定詞;such that可表程度。例:Her cruelty is such that we all hate her.
十、表原因的從屬連詞now that\in that
【例23】_______you’ve got a chance,you might as well make full use of it.
A.Now thatB.After C.AlthoughD.As soon as
【答案與解析】A。now that既然,從now可知,使用時應注意時間;in that表“在于”,屬正式用語,不置于句首。例:
Human beings are different from animals in that they can use language as a tool to communicate.
十一、表時間的從屬連詞when\while\as
【例24】-______I’m going to the post office.
-________you’re there,can you get me some stamps?
A.As B.WhileC.BecauseD.If
【例25】Mother was worried because little Alice was ill,especially ________ Father was away in France.
A.as  B.thatC.during D.if
【例26】—Where’s that report?
—I brought it to you_______you were in Mr.Black’s office yesterday.
A.ifB.when C.becauseD.before
【答案與解析】BAB。when\while\as用法區別是:主從句動作先后發生用when;兩個較長動作同時發生用while,從句謂語動詞為延續性動詞,還可譯作“趁著”;特別強調主從句動作同時發生時用as,譯作“一邊……一邊”,as還可表“隨著”。例:
(1)Strike while the iron is hot.
(2)As the day went on,the weather got worse.
十二、表時間的從屬連詞since\until\before
【例27】It is difficult for us to learn a lesson in life______we’ve actually had that lesson.
A.untilB.afterC.sinceD.when
【例28】That was really a splendid evening.It’s years_____I enjoyed myself so much.
A.whenB.thatC.beforeD.since
【答案與解析】AD。since\until\before強調的時間不盡相同,since表示“自從……以來”,until表示“直到……止”,before表示“在……之前”;若主句謂語動詞為非延續性動詞的否定式,使用until和before基本上沒有區別。例:He didn’t leave until\before the rain stopped.
十三、表時間的從屬連詞before\after
【例29】 The field research will take Joan and Paul about five months;it will be a long time _____we meet them again.
A.afterB.beforeC.sinceD.when
【答案與解析】B。連詞before和after表示時間的差異是:before表“在……之前”,此詞在具體語境中有不同含義,可譯作“寧愿、不知不覺、要不然、否則”等。尤見于“It will be\was+時間+before…,”句型中;而after表“在……之后”,與before相反。
十四、表示時間的句型It’s+時間+when\since\before\that中連詞
【例30】-Did Jack come early last night?
-Yes.It was not yet eight o’clock_____he arrived home.
A.beforeB.whenC.thatD.until
【例31】 It wasn’t until nearly a month later_____I received the manager’s reply.
A.sinceB.whenC.asD.that
【答案與解析】BD。例30題考查從屬連詞,涉及句式結構“It’s…when”從句的用法。when常接在時間名詞之后。句意:他到家時還不到八點。注意句型It’s+時間+when\since\before\that中連詞的選擇。若將it、 be動詞和連接詞刪除,整個句子句意完整,那么此句為強調句,否則為時間狀語從句或名詞性從句。
十五、關聯連詞no sooner…than…\hardly…when…
【例32】-Did Linda see the traffic accident?
-No,no sooner_____than it happened.
A.had she goneB.she had gone  C.has she goneD.she has gone
【答案與解析】A。no sooner…than…和hardly…when…相當于as soon as之意,從句謂語動詞用一般過去時,主句謂語動詞用過去完成時。置于句首時,主句的謂語要部分倒裝。例:
Hardly had he got into the room when the telephone rang.
十六、引導讓步狀語從句的連接詞however\no matter how
【例33】This is a very interesting book.I’ll buy it,_____.
A.how much may it cost B.it may cost
C.however much it may cost  D.how may it cost
【答案與解析】C。however\no matter how的區別是:前者可引導名詞性從句和讓步狀語從句,而后者只能引導狀語從句。另外,however還可用作連接副詞,與標點符號連用,表示然而。
例:“Maybe I should drop out,” I thought as I moved on.However,I decided to keep going.
十七、連接詞even if\as if
【例34】Allow children the space to voice their opinions,_____they are different from your own.
A.untilB.even if C.unlessD.as though
【答案與解析】B。even if與as if只是形似,意義上差別很大。前者引導讓步狀語從句,用法同even though;后者引導方式狀語從句,表“似乎”。例:
Elize remember everything exactly as if it happened yesterday.
十八、引導名詞性從句連接詞what\that
【例35】There is much chance_____Bill will recover from his injury in time for the race.
A.that  B.which  C.until  D.if
【例36】_____matters most in learning English is enough practice.
A.WhatB.WhyC.WhereD.Which
【答案與解析】AA。what與that區別是:前者擔任句子成分,有一定意義;后者不擔任句子成分,無具體意義,只起連接作用,賓語從句中常省略,其他從句中不可省略。
十九、引導定語從句的when\since when
【例37】The book was written in 1946,_____the education system has witnessed great changes.
A.when B.during which  C.since thenD.since when
【答案與解析】D。前后句用逗號隔開,為主從關系,排除選項C;從定語從句時態上考慮,只有since常與完成時連用,故排除選項A和B。when除用作關系副詞引導定語從句外,還可用作代詞,和介詞since\by等連用,可引起疑問句或定語從句。又如:Since when has the country been open to international trade?
二十、引導名詞性從句連接詞what\which
【例38】There are so many kinds of tape recorders on sale that I can’t make up my mind_____to buy.
A.whatB.whichC.howD.where
【例39】It is none of your business_____other people think about you.Believe yourself.
A.howB.whatC.whichD.when
【答案與解析】BB。what與which共同點是均可指“什么”,擔任句子成分,起連接作用;不同點是:what指不定范圍的“什么”,而which指一定范圍內的“什么”,常譯作“哪一個”。
