高三英语语法知识点总结

虚拟语气在一些特殊词中的使用或含蓄条件句

1.wish后的宾语从句。

与现在愿望不一致，用主语十过去时，例如：

I wi。hIwere you.

与过去愿望不一致，用主语+had+过去分词，例如：Iwish I had visited the White House whenI was in the States与将来愿望不一致，用主语+would (could)+原形。

2.It's time句型：当lt's tine后用that从句时应该为主i吾+should+动词原形或主语十过去时，例如：It，s time thatyou went to school.或It's time that you should go to schooL

3- If only引起的感叹句相当于“How I wish+宾语从句”。

(l)If only he could come.他要能来就好了。

(2)If only I had known the answer.我要早知道答案就好了。

4.WOuld rather，as if(though)引导的从句也需使用虚拟语气，表示过去的情况用过去完成时，表示现在与将来的情况用过去时，例如：

(l)I'd rather you posted the letter right away.

(2)She loves the children as if they were hers.

5.含蓄虚拟条件句含蓄条件句是指句中没有明显的虚拟条件句，而是利用其他手段来暗示存在虚拟条件。但是这类隐含式虚拟条件句往往都可以转化为if引导的条件句。常用来表示含蓄虚拟条件的手段有：

(1)介词或介词短语。如but for，but that，without,in case of, under more favorable condition等。

(2)连词。如so that, unless, in case, supposing,lest, provided(倘若……)，for fear that(唯恐)，in orderthat, on condition that, if only(要是……就好了)等。

注意：lest, for fear that和in case引起的从句中谓语动词多用should+动词原形，但也可以不用虚拟语气，而用动词的陈述语气形式。例如：The foreign teacher spokeslowly in case we misunderstood him这位外籍教师说得很慢以免我们误解。

(3)通过上下文及内在含义，句中往往有but,otherwise, unfortunately等类似转折词。

without, but. but for, otherwise引起的短语或句子常暗含着含蓄条件。例如：

①Without you,1 would never know him

②But for your oooperation, we wouldn't have done it

③But that she was afraid, she would have said no. .

④i would be most glad to help you, butI am busy now.

⑤I would have come to the party yesterday, but ljwas working.

⑥I am busy now, otherwise l would do you the favor!

高三英语语法知识点归纳

It的用法

1、It除了代替人和物以外,还可以作形式主语.而真正的主语(不定式、动名词或从句)则放于谓语或表语之后.

例如：It is nor easy to finish the work in two days.

然而有少数表语之后接动名词作真正的主语.这些表语是：无助(no help)、无用(no use)、没好处(no good);工作(hard work)、费时(a waste of time)、又危险(a danger).

例如：A、It is no use crying over spilt milk.

B、It is a waste of time waiting for him.

2、It还可以作形式宾语.通常下列动词后面可接it作形式宾语：2f2tcjm(find,feel,think,take,consider,judge, make).

例如：A、He made it clear that he was not interested in this subject.

B、I think it no use arguing with him.

3、It用于强调句式.要强调句子的某一部分(主语、宾语、 状语),可以把it当作先行词.这种句子的结构是：It is(was)+ 被强调部分+that(who)+句子的其余部分.

例如：A、It iS Professor Lin who teaches us English—(强调主语)

B、It was in Shanghai that l saw the film.—(强调状语)

C、It was in 1990 that I worked in the factory.(同上)

但要注意与定语从句的区别.

例如：D、It was 1990 when I worked in the factory.(定语从句)

在强调句式里,我们把强调结构It is(was)…that除去,句子还很完整.如例句C.而例句D就不能.
