高二人教英语语法知识点
英语是高中生学好高中的重要组成部分，学好直接影响着高中三年的成绩。接下来本站小编为你整理了高二人教英语语法知识点，一起来看看吧。
一、不定式做主语：
1、不定式做主语一般表示具体的某次动作。===动名词doing表示习惯的，经常的动作。
e.g:Tofinishthebuildinginamonthisdifficult.
Todosuchthingsisfoolish.
Toseeistobelieve.(对等)
注:1).不定式作主语时,谓语用单数
2).当主语较长，谓语较短时，常用it做形式主语，而将不定式放到谓语的后面。
it做形式主语，不定式放在谓语动词之后常用于下列结构中：
(1)Itis/was+adj.+…
(2)Itis+adj.+forsb.+todo…
Itiseasy/difficult/hard/foolish/unwise/right/wrong/unnecessary
(3)itis+a+名词+todo...
Itisapity/apleasure/apleasantthing/one’sduty/anhonor/ashame/acrime/noeasyjob…todo
Ittakes(sb.)sometime/courage/patience…todo…
Itrequirescourage/patience/hardwork…todo…
*注意:probable和possible均可作表语，但possible可以用不定式作真实主语，而probable不能用不定式作真实主语。
Itisprobableforhimtocometothemeeting.(错)
Itispossibleforhimtocometothemeeting.
Itispossible/probablethathewillcometothemeeting.
二、不定式做表语
主语是以aimdutyhopeideaintentionplanjobsuggestionwishpurposetask等为中心词的名词词组或以what引导的名词性从句表示，后面的不定式说明其内容,不定式作表语常表示将来或现在的动作或状态。
eg:Myideaistoclimbthemountainfromthenorth.
Yourmistakewasnottowritethatletter.
WhatIwouldsuggestistostartworkatonce.
三、动词不定式作宾语
以不定式结构为宾语的动词有：
ask,agree,care,choose,demand,decide,expect,fail,help,hope,learn,manage,offer,plan,prepare,pretend,promise,refuse,want,wish等只能用动词不定式作宾语
口诀(接不定式作宾语的动词)

快准备有希望(preparehopewishexpect)
同意否供选择(agreeofferchoose)
决定了已答应(decidebedeterminedpromise)

Confused by the new surroundings, I was hit by the lack of fresh air.

过去分词作状语：过去分词作状语时，说明动作发生的背景或情况，其等同于一个状语从句。vt 过去分词作状语时与主句主语构成被动关系，表示被动和完成，vi 过去分词表示状态或动作的完成。

1 作原因状语，等于as / since / because 引导从句
Moved by what she said ,we couldn’t help crying . = ( As we are moved by what she said …
2 作时间状语，等于when 引导时间从句，如果分词表示的动作与谓语的动作同时发生，可在分词前加when/ while / until 等使时间意义更明确。
When heated , water can be changed into steam .

She sat by the window , lost in thought .
5 作让步状语

6 独立主格结构： 当分词的逻辑主语不是主句主语时，分词可以有自己独立的逻辑主语，这种结构称为独立主格结构。常用来表示伴随情况。
The boy rushed into the classroom , his face covered with sweat .
All things considered ,your article is of great value than hers .
Rewrite with proper conjunctions
Example : United we stand, divided we fall.
If we are united, we will stand, but if we are divided,we will fall.

现在分词与过去分词作状语
现在分词作状语时，与其逻辑主语之间是主动关系，;而过去分词与其逻辑主语之间则表示被动关系。
Seeing these pictures, I couldn’t help thinking of those days when I was in Beijing . Seen from the top of a thirty-storeyed building, Beijing looks more magnificent. (see)
选择现在分词还是过去分词，关键看主句的主语。如分词的动作是主句的主语发出，分词就选用现在分词，反之就用过去分词。例如：
Used for a long time, the book looks old.
由于用了很长时间，这本书看上去很旧。
Using the book, I find it useful.
在使用的过程中，我发现这本书很有用
