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。

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.
