高二英语语法知识点1
【现在完成进行时】
1. 现在完成进行时的定义
现在完成进行时表示某动作从过去某个时间开始，一直延续到现在，并且还有可能持续下去。如：
We have been waiting for him for two hours. 我们等他等了两个小时。
2. 现在完成进行时的结构
现在完成进行时由“have /has been + 现在分词”构成。
3. 现在完成进行时的应用
现在完成进行时所用的时间状语：this month / week / year, these days, recently / lately, in the past few + 时间段, since +时间点, for + 时间段。如：
They have been building the bridge for two month. 两个月来他们一直在修桥。
They have been planting trees this month. 这个月来他们一直在植树。
4. 现在完成进行时与现在完成时的区别
(1) 现在完成时强调动作的完成，而现在完成进行时强调动作的延续，因此，表示动作的完成，只能用现在完成时，而不能用现在完成进行时。如：
He has changed his idea. 他改变了想法。
(2) 在表示动作的延续时，虽然既可用现在完成时，也可用现在完成进行时，但现在完成进行时强调动作的进行。因此在需要明确表示动作还要持续下去时，应用现在完成进行时。如：
We have been studying here for two years. 我们在这儿已经学习了两年了。
(3) 有些延续性动词(如 keep, learn, live, stay, study, work等)，用于现在完成时或现在完成进行时的区别不大。如：
I have lived here for many years.=I have been living here for many years. 我在这儿住了多年了。

主语从句
1. 定义：用作主语的从句叫做主语从句。
2. 构成：关联词+简单句
3. 引导主语从句的关联词有三类：
(1) 从属连词that。 如：That they were in truth sisters was clear from the facial resemblance between them.
很明显，她们确是亲姐妹，她们的脸型很相似。
(2) 从属连词whether。如：
Whether he’ll come here isn’t clear. 他是否会来这里还不清楚。
(3) 连接代词who, whom, whose, what, which, whoever, whatever, whichever
连接副词 where, when, how, why。如：
What she did is not yet known. 她干了什么尚不清楚。
How this happened is not clear to anyone. 这事怎样发生的，谁也不清楚。
Whoever comes is welcome. 不论谁来都欢迎。
Wherever you are is my home ---- my only home. 你所在的任何地方就是我的家----我的家。
解释：
1. 主语从句能用it作形式上的主语。常以it作形式主语的句型有：
A. It+be+形容词(obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain, probable, etc.)+that从句。如：
It is certain that she will do well in her exam. 毫无疑问她考试成绩会很好。
It is probable that he told her everything. 很可能他把一切都告诉她了。
B. It+be+名词词组(no wonder, an honour, a good thing, a pity, no surprise, etc.)+that从句。如：
It’s a pity that we can’t go. 很遗憾我们不能去。
It’s no surprise that our team should have won the game. 我们没赢这场比赛真意外。
C. It+be+过去分词(said, reported, thought, expected, decided, announced

1.倒装句的定义：英语最基本的词序是主语在谓语动词的前面。
如果把谓语动词放在主语前面，就叫做倒装。
2. 倒装句的构成
a) 完全倒装
将句子的主语和谓语完全颠倒过来，称之为完全倒装。
Are you from here? 你是本地人吗?
Now comes the chance. 机会来了。
b) 部分倒装
只将助动词、系动词或情态动词移至主语之前，谓语的其他部分仍保留在主语的后面，称之为部分倒装。例如：
Has he come? 他来了吗?
Seldom have we felt as comfortable as here. 我们难得像在这里这么舒服。
Only in this way can we do the work better.
只有这样我们才能把工作做得更好。
3. 倒装的原因
a) 句子语法结构的需要。例如：
Did you attend the meeting? 你参加会议了吗?
Long live peace! 和平万岁!
b) 一些句型的固定用法。例如：
Such were his last words. 他最后的话就是这样。
c)强调的需要。倒装以后，句子更加流畅生动。例如：
Never before have we seen such a sight. 以前我们从来没有见过这样的情景。
Before us lay a lot of difficulties. 在我们前面有很多困难。
Often did we warn them not to do so. 我们曾多次警告他们不要这样做。
4. 倒装句的基本用法
a) 构成疑问句(除对主语或主语之定语提问的特殊疑问句外)：
When are we going to drink to your happiness? 我们什么时候喝你们的喜酒?
Have you seen the film? 你看了那部电影吗?
b) 在以here, there, now, then, in, away, up down等副词开头的句子中:
Away went the crowd one by one. 人们一个一个地离去。
Here comes our teacher! 我们的老师来了!
c) 副词only+状语放在句首时:
Only then did he realize his mistakes . 只有在那时他才认识到自己的错误。
Only in this way can you learn maths well . 只有用这种方法你才能学好数学。
d) 含有否定意义的副词或连词(如little, hardly, never, rarely, no sooner…than等)放在句首时:
Little did I think that he could be back alive. 我没有想到他竟能活着回来。
Not until New Year’s Day shall I give you a gift. 我要到元旦那天才能给你礼物。
Hardly had the train arrived at the station when we ran towards the sleeping car looking for our guests.
火车刚一进站，我们就跑到卧车那儿去找我们的客人。
e) 副词so或 neither(nor)在句首:
He is interested in pop-songs, and so am I.他对流行歌曲感兴趣，我也如此。
He hasn’t been to the countryside, neither does he want to go there.他没有去过农村，他也不想去那里。
f) 在方式状语thus开头的句子中及程度状语so放句首:
Thus ended his life. 这样结束了他的生命。
So loudly did he speak that even people in the next room could hear him . 他讲话的声音那样大，连隔壁屋子里的人都听得见。

一、非谓语动词
“非谓语动词”可分为动词不定式、动名词和分词.它在句子中的作用很多：除了不作谓语外,它可以充当主语、宾语、表语、定语、状语与复合宾语(主语补语或宾语补语).有些及物动词后面接不带to的不定式作复合宾语.这些动词归纳如下：一感(feel).二听(hear,listen to),三让(have,1et, make),四看(see,watCh,notice,observe).再加上help somebody(to)do something和美国英语look at somebody do somthing.还有“二让”属特殊：get somebody to do something 与keep somebody doing.而有些及物动词后面接动名词(the -ing form)作宾语.这些动词归纳为一句话：Papa C makes friends.这是由如下动词的开头字母组成：permit,advise, practise,avoid,consider,mind, allow,keep,enjoy,suggest, finish,risk,imagine,escape,need,delay,stand(忍受). 为了容易记住,也可以编成顺口溜：“允许完成练习,建议避免冒险,考虑延期逃跑,喜欢保持想象,需要反对忍受”.其相对应的动词依次是：permit/allow,finish,practise;
advise/suggest, avoid,risk： consider, delay, escape/miss; enjoy/appreciate, keep, imagine; need/want/require,mind. can't help/can’t stand.
二、复合句
1、学生最容易混淆的是定语从句与同位语从句的区别.
例如：A、The news that our team has won the match is true. (同位语从句)
B、The news that he told us surprised everybody here. (定语从句)
关键的区别在于连接或关系代词that：有意义的是定语, 无意义的是同位.因为引导定语从句的that在从句中作主语或 宾语,而引导同位语从句的that只起到连接词的作用.
2、接着容易混淆的是引导定语从句的关系代词that与 which：that之前是不定(代词)、序数(词)、(形容词)级：which之前是介词短语与逗号(非限制性).
例如：A、All that we have to do is to practise every day.
B、The first lesson that I learned will never be forgotten.
C、I have lost my pen,which I like very much.
D、The house in front of which there is a garden is my home.
三、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.
