3、ficial. How unbelievable to get it back! I mean, someone _it. Awill have stolen Bmight have stolen Cshould have stolen Dmust have stolen 易誤選D 許多考生認(rèn)為此處表示某人肯定把手提包偷走了，結(jié)果導(dǎo)致誤選D。其實(shí)根據(jù)語境可推斷出此處表示可能性較小的推測(cè)：手提包當(dāng)時(shí)有可能會(huì)被偷走。故答案為B。 Dont play with the dog, Jack, for it _be dangerous at times. Ashall Bshould Ccan Dmus

4、t 易誤選A、D 很多考生認(rèn)為玩狗將很危險(xiǎn)或者肯定很危險(xiǎn)，從而誤選A或D。其實(shí)，shall用于第二、第三人稱表示“允諾，命令，警告，威脅”等；should表示“應(yīng)該”；must表示“必須，一定”等；而can除了表示“能，能夠”外，還可表示“(有時(shí))會(huì)，可能會(huì)”等。根據(jù)語境及情態(tài)動(dòng)詞的意義可知，正確答案為C。 I think Ill give Bob a ring. You _You havent been in touch with him for ages. Awill Bmay Chave to Dshould 易誤選C 考生有可能誤選C項(xiàng)。分析句意可知，表示原則上或道義上“應(yīng)該”的情態(tài)動(dòng)

5、詞should用在這里正合適。故選D。 _fired, your health care and other benefits will not be immediately cut off. AWould you be BShould you be CCould you be DMay you be 易誤選D 考生容易誤選D項(xiàng)，但是may用于倒裝結(jié)構(gòu)時(shí)表示祝福、祝愿，用在此處不合適。分析句意可知，橫線處所填的內(nèi)容表示條件。當(dāng)條件狀語從句的謂語中含有were，should, had時(shí)，可以將這些詞移到句首，此時(shí)須把連詞if省略，故選B。此處相當(dāng)于If you should be。 Dont y

6、ou think it necessary that he _to Miami but to New York? I agree, but the problem is _he has refused to. Awill not be sent; that Bnot be sent; that Cshould not be sent; what Dshould not sent; what 易誤選A、C 本題是對(duì)虛擬語氣和省略的考查，考生若是對(duì)相關(guān)知識(shí)掌握得不牢固，便可能誤選A項(xiàng)或C項(xiàng)。第一空，在“Itbenecessary/right/important/essential/impossib

7、e等that從句”結(jié)構(gòu)中，從句的謂語動(dòng)詞部分要用(should)do結(jié)構(gòu)，此處的should不可以換用其他的情態(tài)動(dòng)詞，故選項(xiàng)A被排除；動(dòng)詞send與主語he之間為動(dòng)賓關(guān)系，故選項(xiàng)D也被排除；第二空，題干中的“he has refused to”是一個(gè)省略結(jié)構(gòu)，其完整形式為“he has refused to be sent to New York”，該句子不缺成分，故應(yīng)填上只起連接作用、在句中不作任何成分、沒有任何含義的that。that在本題中引導(dǎo)表語從句。故選B。 Thank you for all your hard work last week, I dont think we _it

8、 without you. Acan manage Bcould have managed Ccould manage Dcan have manage 易誤選A 這是一種含蓄的虛擬語氣，句中的虛擬條件通過介詞短語without you來體現(xiàn)，句中l(wèi)ast week表明是過去的事情，所以這里的without you 相當(dāng)于“if it had not been for you”，故選B?？伎键c(diǎn)點(diǎn) 精精析析 基 礎(chǔ) 盤 點(diǎn) 熱 門 考 點(diǎn) 1采用(should)do結(jié)構(gòu)“虛擬語氣”； 2would rather(that)/if only/as if/it be(high)time(that)等

Ahad Bhas Chave Dwould have 答案C考查虛擬語氣。本題中有requirement，后跟動(dòng)詞原形。Their requirement that he _one years experience is reasonable. Adrive; not answer Bwas driving; shoul

12、nd, urge, propose, advise等。賓語從句中的虛擬語氣結(jié)構(gòu)為“should動(dòng)詞原形”，should可以省略。 注意：當(dāng)suggest表示“暗示，表明”之意，insist表示“堅(jiān)持說”之意時(shí)，suggest/insist后的賓語從句不使用虛擬語氣，應(yīng)使用陳述語氣。 The man insisted that he had never stolen the money. 那個(gè)人堅(jiān)持說他沒有偷錢。 等名詞后的表語從句和同位語從句中要用虛擬語氣，其構(gòu)成是“should動(dòng)詞原形”，should可以省略。 “一、二、三、四”法 一、堅(jiān)持二、命令三、需要四、建議 與此類詞匯邏輯相關(guān)聯(lián)的名

Awerent Bhadnt been Cwouldnt be Dwouldnt have been 答案A句意：孩子們都到哪里去了？宴會(huì)就要被他們徹底破壞了。我希望他們不要總是遲到。本題考查虛擬語氣。wish后跟that從句，從句部分采用虛擬語氣，與現(xiàn)在事實(shí)相反的用一般過去時(shí)，與過去事實(shí)相反的用過去完成時(shí)。本題表示與現(xiàn)在事實(shí)相反，所以用一般過去時(shí)，故正確答案為A項(xiàng)。(2011北

Ado Bdont Cdidnt Ddidnt do 答案D本題考查虛擬語氣。在would rather后的賓語從句中也用虛擬語氣，其結(jié)構(gòu)為would rather sb過去時(shí)。故選D。 Awere Bhad been Cis Dhas been 答案A本題考查虛擬語氣。as if引導(dǎo)的從句謂語動(dòng)詞與主句謂語動(dòng)詞所表達(dá)的動(dòng)作同時(shí)發(fā)生，as if引導(dǎo)的從句謂語動(dòng)詞用一般過去時(shí)。故選A。Most in

18、 he _ away for ages. Ais Bwere Chas been Dhad been 答案B句意：不要這么拿著這個(gè)花瓶，就好像它是鋼制成似的。本題考查虛擬語氣。as if意為“好像”，分析句意可知as if后面的句子須使用虛擬語氣，并且所述情況是對(duì)現(xiàn)在事實(shí)的假設(shè)，因此使用一般過去時(shí)，故選擇B項(xiàng)。(2012北京卷北京卷)Dont handle the vase as if it_made of steel. 1wish后面的賓語從句一般用虛擬語氣，表示一種不可能 實(shí)現(xiàn)的愿望。其謂語動(dòng)詞構(gòu)成形式為：if only句子句子How I wish(that)從句從句If only I w
