英语虚拟语气练习1.（2020·江苏）If I hadn't been faced with so many barriers, I _____whereI am.A. won't beB. wouldn't have beenC. wouldn't beD. shouldn't have been【答案】C【解析】句意：如果我没有面对那么多的障碍，我现在就不会在这里。
此处是错综时间虚拟语气，根据空后where I am可知，此处是与现在事实相反的假设，主句谓语动词应使用would/could/might/should+do。
故选C。
【总结】考查虚拟语气，本题涉及错综时间虚拟语气的应用。

相信我，如果我有时间的话，我会参加的。
could have afforded the time表示未曾实现的能力：即表示过去本来有能力可以做某事的，但实际上没有那样去做，通常译为"本来可以""本来能力。
所以本句表示我本可以抽出时间去参加生日聚会，但是我没有。
would+have+done"虚拟语气，表示对过去事情的假设，意思是"本来会做"。
在本句中表示本来会参加的，但实际上没有参加。
故选C。
【总结】考查虚拟语气，本题涉及对过去事情的假设。

高考英语情态动词语法专题训练及答案(完整版)
高考英语情态动词语法专题训练(名师精讲必考语法知识点+实战真题，值得下载练习)一、情态动词的定义情态动词是一种本身有一定的词义，表示说话人的情绪、态度或语气的动词，但不能单独作谓语，只能和其他动词原形构成谓语。
情态动词数量不多，但用途广泛，主要有：can (could), may (might), must, need, ought to, dare (dared), shall (should), will (would) .二、情态动词的位置情态动词在句中放在谓语动词之前，谓语动词前若有助动词，则在助动词之前，疑问句中，情态动词放在主语之前。
•I can see you. Come here. 我能看见你，过来吧。
•He must have been away. 他一定走了。
•What can I do for you? 你要什么？•How dare you treat us like that! 你怎么敢那样对待我们!三、情态动词的语法特征1）情态动词不能表示正在发生或已经发生的事情，只表示期待或估计某事的发生。
2）情态动词除ought 和have 外，后面只能接动词原形。
3）情态动词没有人称，数的变化，即情态动词第三人称单数不加-s。
4）情态动词没有非谓语形式，即没有不定式，分词，等形式。
四、情态动词的用法（一）. can; could; be able toCan 1. 表示“能力”(此时过去时是could) What can you do?2. 表示许可、请求，“可以”。
在口语中，can可以代替may表示许可，而may比较正式。
（此时用could 或might语气更委婉）--Can/Could I go now?--Yes, you can.3 表示推测（否，疑），把握很大,could也可表推测（肯，否，疑）,把握比can小。
--Look! Someone is coming! Who can it be?--It can’t be him. He has gone to Paris.（不可能）He could be here soon. 他很快就来。
