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。在虛擬條件狀語中有were, should, had這三個詞，通常將if省略，主語提前，變成were, sh

6、ould, had＋主語的形式。但要注意，在虛擬條件狀語從句中，省略連詞的倒裝形式的句首不能用動詞的縮略形式。如我們可說Were I not to do, 而不能說Werent I to do。 2．________ so busy, she would come to help you. A．Should my daughter B．Was my daughter not C．If my daughter were not D．If my daughter isnt 解析：選C。考查與現(xiàn)在事實(shí)相反的虛擬語氣。表示與現(xiàn)在的事實(shí)相反的假設(shè)，從句用過去時(shí)。 3．—Sha

7、ll we take the 10：20 train? —No. If we took that train, we ________ too late. A．a(chǎn)rrive B．a(chǎn)rrived C．will arrive D．would arrive 解析：選D?？疾榕c將來情況相反的虛擬語氣。句意：“我們坐10：20的火車怎么樣？”“不行。如果我們坐10：20的火車，我們會到達(dá)的很晚?！敝骶溆谩皐ould/could/might＋動詞原形”，故選D項(xiàng)。 4．—How I want to have studied harder when I was in school

A．dont B．wouldnt C．didnt D．wont 解析：選B?？疾殄e綜時(shí)間條件句的虛擬語氣。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氣。第二句的信息詞had與nowadays則表明了過去與現(xiàn)在的時(shí)間混合。句意：“我在學(xué)校讀書時(shí)，應(yīng)該更努力點(diǎn)啊?！薄耙悄闩α耍憔筒粫乾F(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。”使用

9、wouldnt強(qiáng)調(diào)與現(xiàn)在事實(shí)相反的虛擬語氣。 5．—You ________ better now if you had listened to me. —Next time I will. A．would be B．will be C．would have been D．had been 解析：選A。第一句句意：如果你聽我的，你現(xiàn)在就會好了。由此可判斷這是個混合虛擬條件句，從句與過去相反，主句與現(xiàn)在相反，主句的謂語動詞應(yīng)用would＋動詞原形。 6．—What should we do next! —Well, if Dad ________ here, he

10、would know what to do. A．were B．had been C．be D．is 解析：選A。考查虛擬語氣。根據(jù)語境可知，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：如果我沒有在7歲時(shí)就迷戀上了我們家鄉(xiāng)的Melinda Cox圖書館，我真不能想象我今天會在做什么。根據(jù)句意和I would be doing可以判斷此處為虛擬語氣。at the age of seven是表示過去的時(shí)間狀語，因此if從句中謂語動詞要用had not fallen, 表示對過去情況的假設(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：要是我們沒有錯過公交車的話，我們現(xiàn)在就會正在家里吃午飯了。條件句表示與過去事實(shí)相反的情況，用過去完成時(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：如果我們早點(diǎn)采取有效措施的話，現(xiàn)在這條河就不會污染這么嚴(yán)重。根據(jù) now 可知，主句為與現(xiàn)在事實(shí)相反的虛擬語氣，所以用 would do 的形式，故選B。 4
