【正文】 if引導(dǎo)的是虛擬條件句，因主句謂語動(dòng)詞是might have been，從句就要用had insisted，指對過去情況的虛擬。本句考的是同位語從句中的虛擬語氣結(jié)構(gòu)的用法。常用于這種結(jié)構(gòu)的過去分詞除requested 外還有desired, demanded, ordered, suggested, remended, required等。43. B譯文：旅館管理部門懇請客人11 點(diǎn)之后不要開收音機(jī)。d rather you had not given up the job then. 要是你當(dāng)時(shí)不放棄那個(gè)工作就好了。在would rather, would sooner, would just as soon, might as well 和would prefer 等后面所跟的從句中，也可用虛擬語氣，表示愿望，意為“寧愿”、“但愿”。2)過去完成時(shí)表示與過去事實(shí)相反的愿望。40. A譯文：要是他用心去做，我肯定他能勝任這個(gè)工作。其形式為：1)表示與現(xiàn)在或未來事實(shí)相反的愿望：動(dòng)詞過去時(shí)或“would / could ＋動(dòng)詞原形”。37. B譯文：現(xiàn)在已經(jīng)5點(diǎn)了，你不認(rèn)為我們該回家了嗎？本句涉及“It is (high /about) time (that)...”句型中的虛擬語氣形式?！北揪渖婕耙惶厥饩湫椭械奶摂M語氣。lest, for fear that句中的should 可以省去，in case 句中的should 通常不省去，但是in case 句中可以不用虛擬語氣，而用陳述語氣。35. A譯文：瘋子被關(guān)進(jìn)墻上裝有襯墊的病房，以防他自殺。其形式為：情態(tài)動(dòng)詞“should(ought to,could,might) + have done ，表示該動(dòng)作本來應(yīng)該發(fā)生而實(shí)際并未發(fā)生，含有某種責(zé)怪的口氣。本句涉及含蓄虛擬條件句。31. A譯文：我們不知道他的電話號碼，否則，我們會(huì)打電話給他.本句涉及含蓄虛擬條件句。30. A譯文：當(dāng)你掉下來時(shí)，如果不是我在梯子下面把你接住，恐怕約就不會(huì)這樣笑了。29. B 譯文：要是不太麻煩的話，就給我來杯茶吧。虛擬語氣也常用于“If it were (had been) not for … ”句型中，意為“要不是… … ”。在正式文體中，有時(shí)可把虛擬條件句中的連詞if 省去，而將were, had, should 等助動(dòng)詞（不包括行為動(dòng)詞）提到主語前面，用倒裝結(jié)構(gòu)。本句涉及省略if的虛擬條件句。本句涉及if引導(dǎo)的虛擬條件句，表示與將來事實(shí)相反的假設(shè)。如果句中沒有were, 　had 或should 時(shí)，既不能省略if，也不能倒裝。與過去事實(shí)相反的非真實(shí)條件句中，從句中的謂語動(dòng)詞用“had+過去分詞”，主句的謂語動(dòng)詞用“should 或　would +have+過去分詞”。本句涉及if引導(dǎo)的虛擬條件句，表示與將來事實(shí)相反的假設(shè)。其主要形式有三種：表示對現(xiàn)在情況的虛擬：wish+主語+動(dòng)詞過去式；表示對過去情況的虛擬：wish+主語+had+過去分詞；表示對將來情況的虛擬：wish+主語+would+動(dòng)詞原形。本句涉及虛擬語氣在賓語從句中的使用。本句涉及虛擬語氣在賓語從句中的使用。常這樣用的詞有：mand, desire, demand, order, propose, remend, request, require, suggest 等。英語中在would rather, would sooner, would just as soon, might as well 和would prefer 等后面所跟的從句中，也可用虛擬語氣，表示愿望，意為“寧愿”、“但愿”。② “would rather ( would sooner … ）＋主語＋過去完成時(shí)”表示過去的情況。（但上周并未還）12. D譯文：經(jīng)理寧愿他女兒不和他在同一個(gè)辦公室上班。本句涉及暗含虛擬句。常用的這類詞有suggestion, advise, order, remendation, requirement, mand, proposal等名詞。這一結(jié)構(gòu)中的虛擬用法主要取決于作補(bǔ)語的形容詞 advisable。本句涉及主語從句中的虛擬語氣的使用。本句涉及主語從句中的虛擬語氣的使用。這一結(jié)構(gòu)是否用虛擬語氣取決于主句It is important/… that 中的形容詞（如本句中的important ）。由省略if 的從句(had they been done by hand)中的時(shí)態(tài)可知，C為正確答案。在wish 后面所接的賓語從句中，要用虛擬語氣結(jié)構(gòu)。t done C. don39。m sure he is up to the job ____ he would give his mind to it.A. if only B. in case C. until D. unless41.
