8．might have had had提前，可以看出此處考查的if條件虛擬句的和過去事實(shí)相反的情況，主句用could/might/should＋have done形式，再根據(jù)句意：如果他們知道接下來要發(fā)生什么，他們也許就會(huì)重新考慮了。表示不肯定的猜測，用might have had是最佳答案。]
9．must [考查情態(tài)動(dòng)詞。你一定是Hollis女士。根據(jù)語境可知此處要用must表示肯定推測。]
10．had bought [考查虛擬語氣。在人稱代詞he后，顯然是作謂語；又因他不可能是買下了這個(gè)學(xué)校，故應(yīng)用虛擬語氣，與過去事實(shí)相反，故填had bought。]
11．(should) try [考查虛擬語氣。recommend, suggest, request, command等后面的賓語從句使用虛擬語氣，即should ＋動(dòng)詞原形，should可省略。]
12．would have seen [考查虛擬語氣。根據(jù)otherwise判斷此處是含蓄型的虛擬語氣，表示對過去的虛擬時(shí)，主句用would have done。]
13．shall [考查情態(tài)動(dòng)詞。所有學(xué)生應(yīng)在去學(xué)校之前帶上口罩以防感染禽流感。shall用于第二、第三人稱，表示說話人給對方命令、警告、允諾或威脅。]
14．would [考查虛擬語氣。句尾有now，即主句是對現(xiàn)在的虛擬，應(yīng)該使用would ＋動(dòng)詞原形。]
15．must [考查情態(tài)動(dòng)詞。根據(jù)but可知，此處強(qiáng)調(diào)說話人主觀上認(rèn)為“必須”做某事，要求對方必須在周末前離開。must必須。]
16．(should)be shut [考查虛擬語氣。他要求天黑時(shí)關(guān)閉所有的門以防小偷進(jìn)入。command 表示“命令，要求”后跟賓語從句時(shí)用虛擬語氣should do sth，其中should 可以省略。]
17．could have visited [考查情態(tài)動(dòng)詞。我們“本能夠”去的，但是我們花太多時(shí)間購物，所以沒能去。could have done本能夠做某事(但沒做成)。]
18．(should) be put [考查虛擬語氣。在 “It is suggested that ＋從句”中謂語動(dòng)詞應(yīng)該用should＋動(dòng)詞原形，should可以省略，根據(jù)句意應(yīng)該用被動(dòng)形式。]
19．should [考查情態(tài)動(dòng)詞。句意：同樣數(shù)量的學(xué)生認(rèn)為一個(gè)好的大學(xué)應(yīng)該培養(yǎng)雇主們追求的畢業(yè)生。should應(yīng)該，應(yīng)當(dāng)，表示義務(wù)、責(zé)任，符合語境。]
