【篇一】2020高考英语必背语法知识点 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： To finish the building in a month is difficult. To do such things is foolish. To see is to believe. (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)It is/was +adj.+of sb. to do… (2) It is +adj.+for sb.+to do…
It is easy / difficult / hard / foolish / unwise / right / wrong / unnecessary
(3) it is +a +名词+ to do...
It is a pity / a pleasure / a pleasant thing / one’s duty / an honor / a shame / a crime / no easy job… to do It takes (sb.) some time / courage / patience …to do… It requires courage / patience / hard work… to do…
注意： probable 和 possible 均可作表语，但possible能够用不定式作真实主语， 而probable不能用不定式作真实主语。 It is probable for him to come to the meeting.(错) It is possible for him to come to the meeting. It is possible / probable that he will come to the meeting.

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.过度词用在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.\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)
四、过去分词用在want,wish,like ,expect等表示“希望，愿望”这个类动词后面做宾补。如
The boss wouldn't like the problem discussed at the moment.
I would like my house painted white. I want the suit made to his own measure. I wish the problem settled.
