Ⅲ.單項(xiàng)填空 1．________ to do the work, I should do it some other day. A．If were　　　　　　　　　B．I were C．Were I D．Was I 解析：選C。在虛擬條件狀語(yǔ)中有were, should, had這三個(gè)詞，通常將if省略，主語(yǔ)提前，變成were, sh

6、ould, had＋主語(yǔ)的形式。但要注意，在虛擬條件狀語(yǔ)從句中，省略連詞的倒裝形式的句首不能用動(dòng)詞的縮略形式。如我們可說(shuō)Were I not to do, 而不能說(shuō)Werent I to do。 2．________ so busy, she would come to help you.

8、. —If you had, you ________ work into late every day nowadays. Anyhow, better late than never. A．dont B．wouldnt C．didnt D．wont 解析：選B?？疾殄e(cuò)綜時(shí)間條件句的虛擬語(yǔ)氣。第一句的信息want to have studied就已表明是表示事與愿違的虛擬語(yǔ)氣。第二句的信息詞had與nowadays則表明了過(guò)去與現(xiàn)在的時(shí)間混合。句意：“我在學(xué)校讀書(shū)時(shí)，應(yīng)該更努力點(diǎn)啊?！薄耙悄闩α?，你就不會(huì)是現(xiàn)在每天都工作這么晚了。不管怎樣，亡羊補(bǔ)牢為時(shí)不晚?！笔褂?/p>

10、would know what to do. A．were B．had been C．be D．is 解析：選A。考查虛擬語(yǔ)氣。根據(jù)語(yǔ)境可知，從句表示與現(xiàn)在事實(shí)相反的假設(shè)，故選A項(xiàng)。 7．—Luckily we had arrived before the rain came. —Yes, we ________ in the rain now if we ________ earlier. A．would walk; hadnt started out B．would have walked; havent started out C．would be

11、walking; hadnt started out D．a(chǎn)re walking; didnt start out 解析：選C。由題意知，條件句是與過(guò)去事實(shí)相反；由now 可知主句是與現(xiàn)在事實(shí)相反，所以選C。 8．It is hard for me to imagine what I would be doing today if I ________ in love, at the age of seven, with the Melinda Cox Library in my hometown. A．wouldnt have fallen B．had not fallen

12、C．should fall D．were to fall 解析：選B。句意：如果我沒(méi)有在7歲時(shí)就迷戀上了我們家鄉(xiāng)的Melinda Cox圖書(shū)館，我真不能想象我今天會(huì)在做什么。根據(jù)句意和I would be doing可以判斷此處為虛擬語(yǔ)氣。at the age of seven是表示過(guò)去的時(shí)間狀語(yǔ)，因此if從句中謂語(yǔ)動(dòng)詞要用had not fallen, 表示對(duì)過(guò)去情況的假設(shè)。 9．If we had not missed the bus, we ________ lunch at home now. A．would have had B．would have C

13、．must be having D．would be having 解析：選D。句意：要是我們沒(méi)有錯(cuò)過(guò)公交車(chē)的話，我們現(xiàn)在就會(huì)正在家里吃午飯了。條件句表示與過(guò)去事實(shí)相反的情況，用過(guò)去完成時(shí)；主句表示與現(xiàn)在事實(shí)相反的情況，且此處強(qiáng)調(diào)正在進(jìn)行的動(dòng)作，所以用would be doing。 10．If we had taken such effective measures much earlier, the river ________ so seriously now. A．is not polluted B．would not be polluted C．had not been polluted D．would not have been polluted 解析：選B。句意：如果我們?cè)琰c(diǎn)采取有效措施的話，現(xiàn)在這條河就不會(huì)污染這么嚴(yán)重。根據(jù) now 可知，主句為與現(xiàn)在事實(shí)相反的虛擬語(yǔ)氣，所以用 would do 的形式，故選B。 4
