A．单句填空 1．If I ________(see) it with my own eyes, I wouldn't have believed it. 答案 hadn't seen [句意：如果不是亲眼所见，我是不会相信的。根据主句谓语wouldn't have believed可知，这里考查的是if条件句中对过去情况的虚拟，if条件句中应用过去完成时，故用hadn't seen。] 2．________ (be) there no modern telecommunications, we would have to wait for weeks to get news from around the world. 答案 were [句意：如果没有现代化的电讯，要想收到来自世界各地的消息，我们就不得不等几个星期。本题是if条件句的虚拟语气，表示与现在事实相反。当if省略时，要使用部分倒装。] 3．Ellen is a fantastic dancer. I wish I ________(dance) as well as her. 答案 danced [句意：Ellen是一个极出色的舞者。我希望我能够跳得和她一样好。动词wish后的宾语从句中常用虚拟语气。再根据句意，此处表示对现在情况的一种假设，所以从句中的谓语动词要用一般过去式，故用danced。] 4．They were abroad during the months when we were carrying out the investigation, or they would ________ (come) to our help. 答案 have come [句意：我们在做调查的那几个月，他们在国外，否则他们会来给我们帮忙的。考查虚拟语气。由句意可知设空处表示与过去事实相反的假设。] |
