考点：if引导的条件状语从句点评：虚拟语气是一种特殊的动词形式，用来表示说话人所说的话并不是事实，而是一种假设、愿望、怀疑或推测。
其主要有三种结构：1、与现在事实相反若与现在事实相反，条件从句的谓语用过去式（be通常用were），主句谓语用“should （would, could, might）+动词原形”2、与过去事实相反若与过去事实相反，条件从句的谓语用过去完成时（had+过去分词），主句谓语用“should （would, could, might）+have+过去分词”3、与将来事实相反若与将来事实相反，条件从句的谓语用过去式（be通常用were），主句谓语用“should （would, could, might）+动词原形”：4．I suggest that we Chinese people_______Chinese culture with love and joy everywhere we go. A．spread B．spreading C．to spread D．will spread【答案】A【解析】【详解】句意：我建议我们中国人无论走到哪里都要带着爱心和欢乐来传播中国文化，考查动词suggest后跟虚拟语气。
spread是动词原形；spreading是动名词；to spread是动词不定式；will spread是一般将来时。
动词在这里suggest表示建议，后面宾语从句中使用虚拟语气should+动词原形，should可以省略。
根据句意说明本句的suggest表示建议，故后面使用虚拟语气，省略了should，故选A。
【点睛】动词suggest 后面可以跟名词作宾语，用于句型“suggest sth.”。
如：I suggested a visit. 我提议参观。
suggest 后跟动名词作宾语，如：He suggested going home. 他提议回家。
suggest后面跟that引导的宾语从句时，用虚拟语气，一般省略情态动词should，所以本题选项是A。

考查情态动词。
分析句子及选项“You ___ through that red light, for you ____ an accident.”，你开车闯红灯，因为你事故的，可知是对过去的虚拟，应用情态动词+have done。
此处是不应该开车闯红灯，会引起事故，故选D。
6．Luckily, he wasn’t driving fast at the time of accident; otherwise, I am su re, it _______ a more serious accident.A．would be B．were C．would have been D．had been【答案】C【解析】【详解】句意：幸运的是，事故发生时他没有开快车；否则，我相信，这将是一个更严重的事故。
考查虚拟语气。
根据“wasn’t driving”是过去进行时，所以此处是对过去的虚拟，主句时态应用情态动词+have done，故选C。
7． If my mother ___ I get a grade of 50 in English exam, she would be angry.A．knows B．knewC．has known D．would know【答案】B【解析】试题分析：句意：如果我的母亲知道我英语考试成绩是50分，她会生气的。
表示与现在事实相反的事实，该用一般过去时态，所以选B。
考点：考查虚拟语气。
8．If I __________you. I would buy a big house for my parents.A．be B．am C．was D．were【答案】D【解析】试题分析：句意：如果我是你。
我会买一个大房子给我的父母。

该句描述的是与现状相反的事实故选A。

10． If I _______ you , I _______ do that .A．was , would B．were ; wouldn’tC．am , won’t D．were , won’t【答案】D【解析】试题分析：句意：如果我是你，我不会那样做。
