(一)虚拟语气在if引导的条件句中的易错点

1.If my lawyer had been here last Saturday, he would have prevented me from going.

2.If you had studied hard at school, you would be a college student now.

句子都是虚拟语气在条件句中的使用,从句中都是假设过去的情况,所以用过去完成时,但在主句中,句依然指代过去的情况,谓语动词是would have done,而中含有一个表示现在的时间状语now, 这样就必须将其理解为假设现在的情况,所以谓语动词必须为would/should/might+动词原形,学生在这一点上经常会忽略now的存在,从而按句的形式填写答案。

(二)虚拟语气在名词性从句中的用法

1.在“it is important (strange, natural, necessary……)+that”句子或者“It is decided (ordered,suggested, demanded, advised……)+that”句子中,主语从句中的谓语动词常用(should)+动词原形结构,表示某事“重要”、“必要”、“被决定”等

例如:

1.It is important that everyone (should ) obey the rules all day and all night.

2.It is decided that the meeting (should) be held tomorrow afternoon.

2. suggest, insist 后面指宾语从句时需注意的地方

1)suggest 当“建议”“提出”讲时,其后宾语从句的谓语动词常用“should+动词原形”

例如:He suggested that the work (should) be started at once 他建议立即动工。

类似的动词还有insist坚持,demand要求,desire要求、请求,request请求,require要求、需要,order命令,propose建议,command命令,ask要求,advise建议,prefer宁愿等。 这些动词变被动语态(如:It is suggested + that主语从句)形式后,主语从句谓语动词仍用“(should)+动词原形” 这些动词变名词(如suggestion)后,其后的表语从句和同位语从句中的谓语部分仍用“(should)+动词原形”

2)suggest 当“提出(某看法),暗示,启发”讲时,其后宾语从句的动词不用虚拟语气。

例如:

(1)The police suggested that the thief might be one of the family member

警察局提出窃贼可能是一名家庭成员。

(2)Her yawns suggests that she is sleepy.

她打哈欠表明她困了。

(3)Although he didn't suggest that we __ the decision to swim across the river, but his look suggested that our decision __wrong.

虽然他没提出我们应该终止游过这条河的决定,但他的表情表明我们的决定是错误的。

A stop; was B should stop; be

C stopped;was D stopped; should be

在这个句子中,前一个suggest当“建议”“提出”讲,而后一个作“表明”讲,所以答案为“A”

3)insist作“坚决要求…该…;坚持认为…定要…”讲时,其后宾语从句的谓语动词用“(should)+动词原形”

例如:

I insisted that you (should) be there on time.我坚持认为你应该准时到那里去。

4)insist 作“坚持(意见,看法);坚持说,确信”讲时,其后从句不用虚拟语气。

例如:

He suggested (that) he heard someone in the next room. 他坚持说他听到隔壁屋子里有人。
