38、ing my eyesight.40My grandmother required that I _ (form) the good habit of being polite.答案與解析1would have spent句意：本來你要花一大筆錢給負(fù)責(zé)幫你找寵物的那家機(jī)構(gòu)的，(但)這個(gè)志愿者服務(wù)機(jī)構(gòu)幫你省下了這筆錢。根據(jù)主句的時(shí)態(tài)和句中的otherwise 判斷，這里表示與過去事實(shí)相反的假設(shè)，定語從句中用would have done 表示“本來要做某事”。2should have remained句意：這些話剛一說出口，他就意識到自己本該保持沉默的。由句意可知，此處是對已經(jīng)發(fā)生的動作的虛擬，

39、故用should have done，表示“本該做(但沒有做)某事”。3had forgotten句意：如果你在寄申請的時(shí)候忘記發(fā)送一篇論文會怎么樣？我會被拒絕的。根據(jù)答語可知，問句表示與過去事實(shí)相反的假設(shè)，故應(yīng)用過去完成時(shí)。4should have faced句意：我們是好朋友，本該一起面對這個(gè)問題的，可是你為什么不告訴我？題干中的but表明這里說的是與過去事實(shí)相反的假設(shè)，故用should have faced。5(should) stand此處suggest 表示“建議”，此時(shí)that 引導(dǎo)的賓語從句應(yīng)用虛擬語氣，謂語動詞用“should動詞原形”，且should 可以省略。6were句意

40、：你喜歡這個(gè)學(xué)校嗎？是的。我只希望我們的班級小一些。在wish 后的賓語從句中，謂語動詞要用虛擬語氣，此處表示對現(xiàn)在情況的一種假設(shè)，謂語動詞要用過去式。7knewif only 表示“要是就好了”，謂語動詞使用虛擬語氣。根據(jù)“right now”可知，此處表示對現(xiàn)在的虛擬，因此謂語動詞用過去式。8would be句意：假設(shè)Yeats 在40歲時(shí)就不寫詩了，那么現(xiàn)在他或許就會被評價(jià)為一位名不見經(jīng)傳的詩人了。從句意看，狀語從句敘述的是與過去事實(shí)相反的假設(shè)，從句使用了過去完成時(shí)，而主句的時(shí)間狀語now 表示這里敘述的是與現(xiàn)在事實(shí)相反的結(jié)果，應(yīng)用“would動詞原形”。9would be句意：我要是能

41、贏這場比賽就太好了。但是我想我不夠出色。試試看，很難說。通過句意和won得知，本句為表示將來的虛擬，所以設(shè)空處填would be。10would/could have caused句意：最后你成功了嗎？是的，要不是你的幫助，將/可能會有很大的損失。本句為與過去事實(shí)相反的假設(shè)，所以可用should/would/could/might have done 的形式。但should常用于第一人稱，might 常用于可能性很小。11would句意：馬克斯看上去很緊張。如果是你參加這么激烈的比賽，你也會緊張的。本句中主句和if 條件從句都表示和現(xiàn)在事實(shí)相反的假設(shè)，可改為：You would also lo

42、ok nervous if you had so fierce a competiton.然后考慮采用“sobe動詞/助動詞/情態(tài)動詞主語”句型替換主句形式。12would/should have attended句意：真遺憾你錯(cuò)過了湯普森所作的有關(guān)英國文化的講座。我本想/應(yīng)該參加的，但是我正忙于準(zhǔn)備即將到來的考試。根據(jù)題干中的was busy 可知設(shè)空處表示與過去事實(shí)相反，故答案為would/should have attended。13had locked句意：他們本可以從大火中逃出來，但不幸的是，有人把門鎖上了。根據(jù)題干中“could have escaped”可判斷該句為與過去事實(shí)相反

43、的虛擬語氣，故設(shè)空處表示過去；lock 先于could have escaped，即表示“過去的過去”，故用過去完成時(shí)態(tài)。14didn't句意：我們公司下個(gè)月將組織到香港旅游，我打算帶我媽媽去那里。我寧可你不帶她，畢竟她剛剛從病中恢復(fù)，身體還很虛弱。would rather 接從句的時(shí)候，從句的謂語用一般過去時(shí)表示對現(xiàn)在或?qū)淼奶摂M。15wouldn't/couldn't have finished句意：如果沒有你的及時(shí)幫助，我們就不能按時(shí)完成那項(xiàng)工程了。without your timely help 相當(dāng)于含蓄條件從句，即if it hadn't been for your timely help，是和過去事實(shí)相反的虛擬語氣，故句子謂語動詞用wouldn't/couldn't have done 形式。16wouldn't be句意：如果世界在2012年12月21日滅亡了的話，我們現(xiàn)在就不會享受精彩的生活了。if 從句與過去事實(shí)相反，而主句與現(xiàn)在事實(shí)相反，故答案為wouldn't be。17had been句意：南極地區(qū)被一些人描述得很神奇。我要是去過那
