高三英语语法知识点1
地点状语从句
1、地点状语从句由where,wherever引导。
注意:where与where的区别:Where表特定的地点,而wherever表示非特定的地点。
Wherever=to/at any place where
2、地点状语从句与定语从句的区别
Where引导定语从句时,从句前应有一个表示地点的名词作先行词;而状语从句前则无先行词。
原因状语从句
引导词:because, since,as, now that, not that…, but that…, seeing that, considering that, in that
注意:for也可以表示原因,属并列连词,但不是说明直接原因,而是对某种情况加以推断,用于表示补充说明理由。
目的状语从句
引导词:so, so that, in order that, that, to the end that(以便,为了),in case,for fear that,lest(以免,以防),
目的状语从句中通常有情态动词can,could,may,might,should,would等。
注意:1、in case 还可表示“万一,假如”。
2、目的状语从句可以用so as to, in order to 等不定式代替,但主句和从句的主语必须一致。

英语中过去分词可作宾补,(此时的过去分词一般是及物动词)表被动意义或完成意义,有时两者兼而有之。做宾补的过去分词与宾语有逻辑上的动宾关系,即宾语是过去分词动作的对象。如:
She found the door broken in when she came back.(宾补与宾语有被动的关系,表一种状态。)
一. 过去分词用在表状态的动词keep,leave等的后面。
Eg:They kept the door locked for a long time.
Keep your mouth shut and your eyes open.(谚语:少说多看)
Don't leave such an important thing undone.
Don't leave the windows broken like this all the time.
二.过分词用在get,have,make, 的后面。
1.注意“have +宾语+过去分词”的两种情况:
A)表"让某人做某事/让某事(被人)做"
eg: I have had my bike repaired.
The villagers had many trees planted just then.
B)表"遭遇到某种不幸,受到打击/受....影响,蒙受..... 损失"
Eg:I had my wallet stolen on a bus last month.
The old man had his leg broken in the accident.
He had his leg broken in the match yesterday.(MET1986)
2."make+宾语+过去分词",在这种结构中,过去分词的动词必须是表示结果含义的。如:
They managed to make themselves understood in very simple English.
I raised my voice to make myself heard.
三、过去分词用在感观动词watch,notice,see,hear,listen to ,feel,find等后面。如
When we got to school,we saw the door locked.
We can hear the windows beaten by the heavy rain drops.
He felt himself cheated.
The managers discussed the plan that they would like to see carried out the next year.(NMET2000)

名词性从句中的易错点
(一)that引导的定语从句与同位语从句
定语从句与前面的的名词是修饰与被修饰的关系,“……的名词”,而同位语从句是用来说明前面名词的内容。与that从句同位的名词必须是一些表示事实或概念的抽象名词,如:
fact,news,belief,truth,reply等。
That在定语从句中必须作成分,可用which或who/whom代替,而that在同位语从句中不充当任何句子成分,只起连接作用。如:
①Along with the letter was his promise that he would visit me this coming Christmas.
②Do you still remember the chicken farm that we visited three months ago.
解析:在句①中,that引导同位语从句解释说明promise的内容,that不充当任何句子成分,只起连接作用,而在句②中,that在其引导的定语从句中作动词visited的宾语,对先行词the chicken farm起修饰作用。
(二)名词性从句中,关于it作形式主语和形式宾语的易错点
1) 名词性从句作主语或宾语时,为保持句子平衡,常用it作形式主语或形式宾语。如:
It’s a pity that he don’t come to give a speech.(形式主语)
We think it possible that you can finish the job today.(形式宾语)
2)谓语动词 appreciate, dislike, hate, like, love,
make等接由if或when 引导的宾语从句时往往在从句前加上形式宾语it. 例如:
I would appreciate it if you could come to my birthday party.
3)动词hare, take, hide, punish, put等,后接由that 引导的病因从句式,往往在从句前加形式宾语it. 例如:
① I take it that you will be leaving Shanghai soon.
② we punished it that we had finished the project ahead of time.
4)短语动词answer for, count on depend on, insist on,
see to等后接有that引导的宾语从句时,必须冠以形式宾语it. 例如:① I’m counting on it that you will come. ② She’ll see to it that he goes ahead. 注:作形式主语和形式宾语时只能用it.

虚拟语气谓语动词的几种表现形式
1. 用在虚拟条件句中
例1:I would certainly go if I had the time.
例2:How nice it would be if you could stay a bit longer.
例3:She would have come if we had invited her.
注:如果条件从句中包含有were, had, should或could,有时可把if省略掉,但这时要把were, had, should或could放在主语前面(这种结构在口语中较少使用)。例如:
1)Had we made (= If we had made ) adequate preparations, we might have succeeded.
2)Were there no gravity, there would be no air around us.
3)Should it rain tomorrow, the meeting would be put off.
2. 用在含蓄条件句中
句子中,假设的情况不用条件从句表示出来,而是用一个介词短语来表示,句子的谓语形式也可遵循上表的规则。
这种用法也常见于or, or else, otherwise和but后面的分句中。例如:
1)Without music, the world would be a dull place.
2)But for your help, we would have failed.
3)She would have gone with us, but she didn’t have time.
4)He must have had an accident, or he would have been here then.
3.用在错综时间条件句中
有时候,条件从句表示的动作和主句表示的动作发生的时间并不一致,这时,谓语动词的形式要根据表示的时间来调整,这种句子可称作错综时间条件句。例如:
1)If you hadn’t watched television so late, you wouldn’t be so sleepy now.(此句为时间交错的虚拟条件句,从句表示与过去事实相反的假设,主句则假设与现在情况相反)
2)If you were in better health, we would have allowed you to join them in the work.(从句表示与现在事实相反的假设,主句则表示一种与过去事实相反的设想)
4.用在wish后的宾语从句中
这种句子主要表示愿望,that常省略。若指现在或将来的愿望,从句用过去时;若指过去没有实现的愿望,从句用过去完成时。例如:
1)I wish I had learned to play chess.(与过去事实相反)
2)I wish I remembered his address.(与现在事实相反)
3)I wish he would try again.(对将来情况的假设)
若wish 后的宾语从句中用would,可以表示请求,通常意味着说话人的不快或不满。例如:
1)I wish you would help us.
2)I wish you would stop asking such silly questions.
