27. We're leaving at six o'clock , and hope _____ most of the journey by lunch time .

A. to do     B. to have done     C. to make     D. to have made

答案是B項。要答對這道題需要兩方面的知識。一是不定式的完成體用來表示這個動作發(fā)生在謂語動作之前,或是表示該動作的完成。本題中的不定式的完成體表示的正是該動作的完成,因此這句話可改寫為:We're leaving at six o'clock , and hope that we will have done most the journey by lunch time . (我們將在六點時動身,希望在午飯前走完大半路程。)第二,知識是與journey連用的不同的動詞所具有的不同的內(nèi)涵。詞組to make a journey或to go on a journey 都表示"做一次旅行",在這兩個詞組里a journey是一個整體,但是如果要表示旅程中的一部分,正確的英語則使用do這個動詞,例如:do some / much / most of the journey (走完這個旅程的一部分/大部分/絕大部分)

26. I _____ you somewhere before , but your name has escaped me _____ moment .

A. must see ; for a moment   B. must have seen ; for a moment

C. must see ; for the moment   D. must have seen ; for the moment

答案是D項。must與不定式的完成體連用表示對過去發(fā)生的事持肯定態(tài)度的推斷,在疑問句中用can,在持否定態(tài)度的推斷時用can not 。例如:He must have rid himself of his preumonia last week , for you see , he doesn't cough at all now . (他在上星期肯定治愈了他的肺炎,你看,他現(xiàn)在一點都不咳嗽了。) for a moment表示一個動作延續(xù)了一會兒,而for the moment 則表示"目前;暫時"

25. It's nearly seven o'clock . Jack _____ be here at any moment .

 A. must   B. need  C. should   D. can

答案是C項。根據(jù)語境空白處應填表示具有"隨時可能"意義的情態(tài)動詞。雖然can可以表示可能性,但它往往表示的是對這種可能性的懷疑。例如:Can he still be alive after all these years ? (這么多年之后,他還可能活在人世嗎?) should除具有"應該"詞義之外,還有一個含義是:will probably (將來很可能發(fā)生)又如:His uncle is working among the enemy officials now . Dangerous things should happen to him at any time . (他的叔叔現(xiàn)在在敵人的軍營中工作,危險的事隨時都可能發(fā)生在他身上。)

24. Mrs. Green wants to buy that kind of cloth because she ______ that the cloth _____ very well .

A. has been told ; washes  B. is told ; is washed  C. has been told ; is washed  D. is told ; is washed

答案是A項。根據(jù)語境第一個空白處應該使用現(xiàn)在完成時的被動語態(tài),第二個空白處應該選用washes,因為wash這個動詞也可作不及物動詞使用,它的詞意是"耐洗"。英語中This cloth washes well表達的是:這布很耐洗。

23. -When ______ and visit our exhibition next month ?   -When _______ , I will let you know .

A. will he come ; he will come     B. will he come ; he comes

C. does he come ; he will come     D. does he come ; he comes

答案是B項。第一句中的時間狀語next month確定了這句的一般將來時的時態(tài),然而第二句是由when引導的時間狀語從句,在時間狀語從句中只能用一般現(xiàn)在時表示的是一般將來時。

22. Michael ______ here to see you and he ______ a note on your desk .

A. has come ;  has left  B. has been ; has left  C. has come ; left  D. has been ; left

答案是D項。此處的has been here表示"剛才到這兒來過",從字面上看這個表達方式是現(xiàn)在完成時,但實際上這個表達方式的內(nèi)涵是該人已不在此處了。因此這個動作是發(fā)生在過去的事,那末該在你的書桌上留便條的動作也該用一般過去時

A. have they known ; get      B. did they know ; were going to get

C. do they know ; are going to get   D. had they known ; got

答案是D項。根據(jù)句意分析,他們結(jié)婚已是過去的事,那末,他們互相了解大約一年的時間肯定發(fā)生在結(jié)婚前,發(fā)生在過去某一動作之前的動作,應該使用過去完成時。

20. I really wonder ______ he has posted me many parcels _____ we worked together .

  A. how ; after   B. why ; when  C. when ; before  D. why ; since

答案是D項。英語中的連詞since有這樣的特性:終止其后從句中的延續(xù)性的謂語動詞的動作。第二個空白處填入since之后,這個從句的意思是:自從我們不在一起工作起。此外,since還可使其后從句里的非延續(xù)性的謂語動詞延續(xù)。例如:It is 15 years since he joined the Army . (他參軍已經(jīng)十五年了。)

19. It is a rule in his family that ______ comes home earlier should cook the dinner for the family .

A. Anybody  B. who  C. who that   D. whoever

答案是D項。whoever有兩個詞義,(1)no matter who,在這種用法時引導一個讓步狀語從句,如:Whoever ( = No matter who ) it is , I do not want to see them . (無論他是誰,我都不想見。),又如:The business would be a success , whoever ( no matter who ) owned it . (這個企業(yè)準能興旺發(fā)達,甭管誰是它的主人。);(2)anybody / that,在這種用法時,它連接一個名詞性從句,在本題中它連的是主語從句,又如:I will take whoever ( anybody that ) wants to go to that beautiful park . (我要帶任何想去那個美麗公園的人去那里。)在這一例句中whoever連接的是一個賓語從句。

18. The duties of a policeman are _____ than ____ .

A. dangerouser ; a teacher         B. more dangerous ; a teacher

C. greater danger ; those of a teacher     D. more dangerous ; those of a teacher

答案是D項。英語中由構(gòu)詞法派生出的形容詞或副詞比較級與最高級一律前面加more各the most構(gòu)成。dangerous是由danger派生出的形容詞,因此其比較級是more dangerous ; 在比較句中,一定要使比較的東西是一致的。為了避免重復,需比較的對象如果是單數(shù),應該使用that of…代替,如果需比較的對象是復數(shù),則用those of …,請看以下兩個例句,并理解上述說法:The climate in Florida is as mild as in California . (佛羅里達州的氣候與加州的氣候一樣暖和。) Classes in universities are more difficult than those in colleges . (大學本科的課程比大學專科的課程更難。)
