I 虚拟语气在if 引导的条件句中的易错点。

①if 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①②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①依然指代过去的情况，谓语动词是would have done，而②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①的形式填写答案。

Ⅱ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： it is important that everyone (should ) obey the rules all day and all night.

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）①suggest 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”

②suggest 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：

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。

Her yawns suggests that she is sleepy. 她打哈欠表明她困了。

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; wasB: should stop; be

C: stopped ;wasD: 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”

2）①insist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

②insist 作“坚持（意见，看法）；坚持说，确信”讲时，其后从句不用虚拟语气。

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。
