初中虚拟语气讲解及专项练习与答案带解析.doc

虚拟语气讲解语气 (mood) 是一个动词形式, 用以表示说话者意图或态度。 英语中语气有三种: 陈说语气、 祈使语气和虚拟语气。直陈语气(indicative mood),表示所说话是事实。祈使语气 (imperative mood),表示所说话是请求或命令。虚拟语气(subjunctive mood),表示说话不是事实, 或者是不可能发生情况, 而是一个愿望、 提议或与事实相反假设等。一. 虚拟语气在条件句中应用学习虚拟语气在条件句中使用方法之前我们必需清楚条件句种类: 条件句有真实条件句与非真实条件句(或称虚拟条件句)两种。真实条件句所表假设是可能发生或实现, 句中条件从句与结果主句都用陈说语气。如: If it doesnt rain tomorrow, I will go for a picnic. 假若明天不下雨, 我就去野餐。 Oil floats if you pour it on water. 你如把油倒在水里, 油就浮起来。虚拟条件句所表假设则是不可能或不大可能发生或实现, 句中条件从句与结果主句皆须用虚拟语气。条件从句主句与现在事实相反If 主语 +动词过去式（be过去式用were）should （would, might, could）+动词原形与过去事实相反If 主语 +had+过去分词should （ would, might, could）+ have 过去分词 与未来事实可能相反If 主语 +动词过去式（be过去式用were）; should动词原形; were to动词原形should （would, might, could）+动词原形1. 与现在事实相反虚拟条件句, 条件从句谓语用动词过去式 (be过去式用were), 主句谓语用should （would, might, could）+动词原形。如: If it were not raining, we should go for a picnic.假如现在不下雨话, 我们就出去野餐了。（事实是: 天在下雨, 我们不能出去野餐。表示愿望。）If he came here, he might be able to help you. 假如她来这, 她就能够帮助你了。（事实是: 她没来这, 她不可能帮助你。表示对她良好印象。）2. 与过去事实相反虚拟条件句, 条件从句谓语用had+过去分词, 主句谓语用should （ would, might, could）+ have 过去分词。如: She would have gone to the party if she had been invited.要是当初她被邀请话, 她就会去参与这次聚会了。（事实是: 当初没有些人邀请她, 所以, 她没有来参与聚会。表示后悔。）If she hadnt called me, I would have overslept this morning.今天早上, 她要是不叫我话, 我就会睡过头了。（事实是: 她今天早上叫我了, 我没有睡过头。表示感激。）3. 与未来事实可能相反虚拟条件句, 条件从句谓语用动词过去式(be过去式用were); should动词原形; were to动词原形, 主句用should （would, might, could）+动词原形。如: If I were to be twenty years old next year, I would take the course of French. 明年我要是二十岁, 我就会学法语。（事实是: 我现在已经老了, 明年我学不了法语了。） If it should fail, I would try again.要是失败了, 我会再试一次。（ 事实是: 有可能失败, 可我会再试。表示未知。）虚拟语气专练1.
