be型虚拟语气及倒装

be-型虚拟式的主要用法如下。

用于表示命令、决定、建议等词语之后的that-分句中be-型虚拟式的这一用法又有以下三种情况:a)用在decide, decree, demand,insist,moveorder,prefer,propose,recommend,request,require,suggest,vote等动词之后的that分句中。

但有时出于语法或达到某种修辞目的(强调、承上启下、平衡等)的需要,要把谓语动词放在主语前面,这种语序称作倒装(Inversion)语序。

将谓语动词完全移至主语之前,称完全倒装(Full Inversion);如果只就是把助动词或情态动词放在主语之前,称为部分倒装。

1、 there be结构的倒装在“there be”(或there + appear to be,come,exist, happen to be, lie, live, occur, remain, seem, seem to be, stand, used to be) 雪结构中,倒装形式为完全倒装。

如:There were many students in the reading room in this evening、今晚阅览室里有许多学生。

There is a TV set, a stereo system and a number of chairs in the sitting room、客厅里有一台电视机,一套组合音响与一些椅子。

2、 here,there,now,then等引起的倒装在以here,there,now,then等简短副词引起的句子中(前三个须用一般现在时),动词往往就是be,come,go等时, 这类句子大多带有引起注意的含义。

如:Here comes the bus、公共汽车来了。

Here is the letter you have been looking forward to、您久盼的信在这儿。

但要注意:如果主语就是人称代词,则不用倒装。

如:Here they are、她们在这儿。

3、省略if的非真实条件状语从句中的倒装虚拟结构中的条件从句省去if时,were, had, should须移至主语之前。

如:Had you worked harder at college, you would have got better job、如果您在大学期间读书用功些,现在就会找到一份更好的工作。

Were he better qualified, he would apply for the position、要就是她的条件再好些,她就申请这个职位。

4、副词so, neither, nor等引起的倒装在用so, nor, neither表示“也/不……”这一类结构里其公式就是:肯定: so+be/have/助动词/情态动词＋主语否定: Neither(nor)+be/have/助动词/情态动词＋主语。

如:—He has been to Beijing、她去过北京。

—So have I、我也去过。

—They can’t answer the question、她们不会回答这个问题。

—Neither than I、我也不会。

5、 what,how引起的倒装以What, how开头的感叹句(表语或宾语提前)。

如:What beautiful weather (it is)!多好的天气啊！(表语提前)What a lovely picture he painted!她画了一张多好的画啊！(宾语提前)6、疑问词或连接词引起的倒装在疑问词或连接词whether等引起的从句中。

如:Whatever you may say, I won’t go there、无论您怎样说,我都不会去那儿。

(状语从句中宾语提前)What book he wants is not clear、她要什么书还不清楚。

(主语从句中宾语提前)7、否定词位于句首时引起的倒装(1)、never,seldom,hardly,little,few等引起的倒装否定词never,seldom,rarely,hardly,barely,scarcely,little,few等位于句首时所引起的倒装句通常为部分倒装形式,如果谓语动词为be的一般现在时或一般过去时,则为完全倒装形式。

如:Never shall I forget the days when you were with us、我很少有时间去瞧电影。

(2)、nowhere,no longer,no more等引起的倒装nowhere(无处),no longer(不再),no more(也不)等否定词位于句首时所引起的倒装句通常为部分倒装形式,如果谓语动词为be的一般现在时或一般过去时,则为完全倒装形式:No longer was he in charge of this work、她不再负责这项工作了。

(3)、not until,not a,not in the least等引起的倒装not until(直到……才),not a(一个……也没有),not in the least(一点儿也不),not for a minute/moment(一点儿也不)等位于句首时,通常引起倒装(not a之后的名词作主语时除外),其形式通常为部分倒装形式,如果谓语动词为be的一般现在时或一般过去时,则为完全倒装形式。

如:Not until all the demands had been turned down did the workers decide to go on strike、一直到所有的要求遭到拒绝之后,工人们才决定罢工。
