一般形式：I don't like you smoking. 完成形式：I regret not having taken your advice. 被动形式：This question is far from being solved.
二) 动名词常考的点
1)动名词做主语谓语动词为单数
2)在动名词和不定式中,做为介词的宾语是动名词
3)动名词的否定直接在其前加否定词,通过代词的宾格或所有格形式给出逻辑主语. I would appreciate_______ back this afternoon．
A．you to call B．you call C．your calling D．you're calling
4)有些词后只能接动名词
admit; appreciate; avoid; celebrate; consider; contemplate; defer; delay; deny; detest; discontinue; dislike; dispute; enjoy; it entails; escape; excuse; explain; fancy; feel like; finish; forgive; can't help; hinder; imagine; it involves; keep; it means; mention; mind; miss; it necessitates; pardon; postpone; practice; prevent; recall; report; resent; resist; risk; suggest; understand...
另外还有一些接-ing形式的常用说法：
it's no good; it's no/little/hardly any/ use; it's not/hardly/scarcely use; it's worthwhile; spend money/time; there's no; there's no point in; there's nothing worse than; what's the use/point...
5）有些词后加不定式和动名词均可
remember, forget, try, stop, go on, cease, mean后面用不定式和-ing，意义截然不同。
I remembered to post the letters. (指未来/过去未来的动作)
I remembered posting/having posting the letters (我记得这个动作)
I regret to inform you that… 我很遗憾地通知你…
I regretted having left the firm after twenty years. 为了\二十年前的离开\而遗憾。
try to 努力 You really must try to overcome your shyness. try –ing 试验 Try practicing five hours a day.
I mean to go, but my father would not allow me to. [打算、想] 我想去但父亲不让我去。 To raise wage means increasing purchasing power. [意味着] 赠加工资意味着增加购买力。
prefer的用法：
I prefer to wait here. （所以啊，你不介意的话，我就等下去。） I prefer waiting here.（我正在这里等，我就喜欢这么做。）
I prefer swimming to cycling. （这个句子里面就不能用不定式了。） 四 虚拟语气
这时\虚拟语气\的产生往往是要表达 “本来应该/可能/可以…，而现在却还没有……”。
1. 与现在相反：使用[过去时]： I wish I were not here!
(一般现在?一般过去)
Suppose we were not here.
He loved me as if I were his own son. (一般现在?一般过去) Hope I weren't always losing things! (现在进行?过去进行) If only/If I hadn't been there!
(现在完成?过去完成)
What if I hadn't been waiting right here! (现在完成进行?过去完成进行)
常考句型：It's (high) time (that)…; would rather (that)…
这两个从句，只能表达对现在的看法，所以，从句中只有一般过去时。
和现在事实相反假设：If+_____________, 主语+_____________________
2. 与过去相反：过去完成时；
How nice it is if I had past the test!
How nice it is if I had slept a little more this morning!
和过去事实相反假设：If+_____________, 主语+_____________________
3. 与将来相反？将来的事情没有发生，所以只能推测。
和将来事实相反假设：If+_____________, 主语+_____________________
4虚拟条件句
if 部分，做一个与事实相反的假设（所以只有一般过去和过去完成）；
主句部分，这是表示基于这个假设的推测，一般使用情态动词would，少数情况下使用could/might/should。
注意：两个部分之间，是有逻辑关系，而在两部分的谓语动词时态上，没有必然的联系。 注意，虚拟条件句中的if可以省略，造成were/had提前，产生倒装。
5 一些常见的句型中，就会出现这种虚拟语气，而处于从句之中，should 常常被省略掉 suggest, advise, propose, recommend, plan; demand, order, direct, arrange, command, decide; require, request, insist, suspect.
由于他们的含义中包含\建议，假设，应该\这类的含义，所以，由他们引起的从句中，就会包含有should+原型时态构成的虚拟语气。
这些动词引起的从句还有其他的变形： It's suggested that… My suggestion is that… The only suggestion that...
The only suggestion I can give you now is that…
6 一些形容词引起的表语从句中，也会有同样的情况
important; necessary; essential that
It's natural; strange; incredible
a pity; a shame; no wonder
由lest, for fear that, in case 引起的从句中多使用should
7 用“情态动词＋have ＋done”表示对过去动作推测，高考试题中常用过去时态或过去的时间状语给以暗示。
a． must have done：只能用于肯定句中, 表示对过去动作的肯定推测，常译作“一定做了……”，
其否定形式为can’t/ could have done 疑问式为Can／Could...have done
b．当试题的前后句在动作和意义上构成转折关系时，常借助“but, however, instead”等词来表示过去的动作与客观事实不符，这种结构常见的有：
should have done ／ ought to have done：表示过去本应该做某事而实际上没有做。
