语法专题七：虚拟语气

1. 规则虚拟：即含if 从句的复合句，表示与事实相反。具体时态搭配为： 时间 对将来 对现在 对过去 did(were) had done if从句 同上 would / could / might / should + have done 主句 did(were) / were to + do / should + do would / could / might / should + do 注意： 1) 交叉时间虚拟：即主、从句不在同一时间，注意各自的时态。

2) 虚拟与非虚拟：即一句与事实相反，用虚拟；另一句与事实一致，用实际时态。 3) 虚拟中的倒装：如if从句中含should, had, were等，可将其置于句首，且省略if。 4) 介短、副词代替if从句：如without, but for, in the absence of (如果没有), or, otherwise 2. 表示建议、要求、劝告、命令类词 + 名从中的虚拟，从句动词:(should) do

适用词群：advise, ask, demand, desire, direct(指导，要求), insist, order, propose, recommend,

request, require, suggest, urge等及其它们的名词、形容词、过去分词等，后跟名从。

注意：当insist为“坚持已发生或存在的事实”，suggest为“暗示、表明”时，要

用陈述语气，即实际时态。

3. wish等词 + 从句：从句时态向后退一格： 即表示现在、将来用did / were / was; 表示过去用had done。

适用词群：wish, as if /though, If only(要??就好了), would rather, It is (about / high) time 等。

4. 情态动词 + have done 表虚拟：

should / ought to have done 本应该做（实际没做，含“责备”之意） could / might have done 本可以做（实际未做） needn’t have done 本没必要做 (实际做了) would like / love to have done

would rather have done 本来想要做某事(但未做) had better have done 5. 句型：

1) If it were not for…, I would / should / might / could + do “要不是??，我现在就??。”（对现在的虚拟）

If it had not been for…, I would / should / might / could + have done. “要不是??，我当时就??。”（对过去的虚拟） 2) It is important / necessary / natural / strange …+ 从句 It is a shame / pity / no wonder…+ 从句. 以上从句谓语动词皆为：(should) do

3) had hoped / expected / intended / planned /…+ to do 本希望 / 打算做??(但未做成) 巩固练习：
