Section Ⅲ Grammar——虚拟语气和状语

从句

[语 境 自 主 领 悟]

先观察原句 ①They have recommended that the site be closed and repaired. ②They have suggested that the general public be encouraged to help with the problem. ③Mary speaks as if she were Chinese. ④It's high time that we should have/had a rest. ⑤As long as you've got a raincoat,you'll be OK. ⑥Just stay where you are and don't move. ⑦Hero as he is,he has some shortcomings. ⑧Whatever happens,you're going to have a marvelous time. [语 法 精 要 点 拨] 一、虚拟语气

虚拟语气用于宾语从句、主语从句、表语从句或同位语从句中,常可表示要求、建议、命令、提议、意愿等,其虚拟语气往往是由“(should+)动词原形”构成。

1.宾语从句中的虚拟语气 (1)一般用法

The driver demanded that all the passengers(should) show their tickets to him. 司机要求所有的乘客向他出示车票。 [巧学助记]

宾语从句中常用虚拟语气的动词口诀:

1.①~④句中谓语动词均使用了虚拟语气,①②从句中用should+动词原形,should可省略。 2.⑤~⑧句中黑体部分分别引导条件、地点、让步、让步状语从句。 3.由句⑦可知,as引导让步状语从句时,句子要采用倒装语序。 4.句⑧中黑体部分除引导让步状语从句外,还可引导名词性从句。 后自主感悟 第 1 页

一坚持:insist

二命令:order,command

三建议:advise,suggest,recommend 四要求:require,request,demand,desire

Jane's pale face suggested that she was ill,and her parents suggested that she(should)have a medical examination.

简苍白的脸色暗示她生病了,她父母建议她做一下医疗检查。 She insisted that he was wrong and that he (should) apologize to her. 她坚持认为他错了,并且应该向她道歉。 [名师点津]

suggest表示“暗示;表明”,insist表示“坚持某种说法”时,后面的从句不用虚拟语气。

Her red face suggests that she is a little shy. 她红红的脸蛋暗示她有点儿害羞。 He insisted that he was right. 他坚持声称他是对的。

(2)wish后面的宾语从句要用虚拟语气,从句中谓语动词主要有三种形式:

We wish we had studied more hard when at school. 我们上学时能学习再努力一点就好了。 I wish I were taller.

我的个子要是再高一点儿就好了。 I wish l could fly.我要是能飞就好了。

I wish he would try again.我希望他能再试一次。

虚拟过去:从句谓语用“had+过去分词”

[即时演练3] 单句改错

①His father gave an order that he keeps a diary in English every day.keeps→keep ②I made a suggestion that he will put an advertisement in the local paper. will→should或去掉will 5.在as if/though引导的从句中的虚拟语气 从句用过去时 从句用过去完成时 表示与现在事实相反或对现在情况有所怀疑 表示对过去事实的假设 It seems as if it were spring. 现在好像是春天似的。
