高一英语知识点总结精选篇1
不定式作主语
不定式作主语,往往用it作形式主语,真正的主语不定式放至句子的后面。
例如:It's so nice to hear your voice. 听到你的声音真高兴。
It's necessary for you to lock the car when you do not use it. 不用车的时候,锁车是有必要的。
It's very kind of you to help us. 他帮助我们,他真好。
It seemed selfish of him not to give them anything. 他不给他们任何东西,这显得太自私了。
但是,用不定式作主语的句子中还有一个不定式作表语时,不能用It is… to…的句型。另外,这样的句子,不能用动名词作表语。
It's for sb.和 It's of sb.
这样的句子中,由于表语形容词性质的不同,导致了不定式逻辑主语标志用for或of的区别。
1)for sb. 句型中的形容词一般为表示事物的特征特点,表示客观形式的.形容词,如easy, hard, difficult, interesting, impossible等:例如:
It's very hard for him to study two languages. 对他来说学两门外语是很难的。
2)of sb句型中的形容词一般为表示性格,品德,心智能力,表示主观感情或态度的形容词,如good, kind, nice, clever, foolish, right。例如:
It's very nice of you to help me. 你来帮助我,你真是太好了。
用for还是用of 的另一种辨别方法:
用介词for或of后面的逻辑主语作句子的主语,用介词前边的形容词作表语,造个句子。如果通顺用of,不通则用for。例如:
You are nice. (通顺,所以应用of)。
He is hard. (非所表达的意思,不通,因此用for。)

延续动词与瞬间动词
1)用于完成时的区别
延续动词表示经验、经历;瞬间动词表示行为的结果,不能与表示段的`时间状语连用。 He has completed the work.他已完成了那项工作。 (表结果)
I've known him since then.我从那时起就认识他了。(表经历)
2)用于till / until从句的差异
延续动词用于肯定句,表示"做……直到……"瞬间动词用于否定句,表示"到……,才……" He didn't come back until ten o'clock.
他到10点才回来。
He slept until ten o'clock.
他一直睡到10点。
典型例题
1. You don't need to describe her. I ___ her several times.
A. had met B. have met C. met D. meet
答案B.首先本题后句强调对现在的影响,我知道她的模样,你不用描述。再次,several times告知为反复发生的动作,因此用现在完成时。
2.---I'm sorry to keep you waiting.
---Oh, not at all. I ___ here only a few minutes.
A. have been B. had been C. was D. will be
答案A.等待的动作由过去开始,持续到现在,应用现在完成时。
用一般过去时代替完成时
1)两个动作如按顺序发生,又不强调先后,或用then,and,but等连词时,多用一般过去时。
When she saw the mouse,she screamed.
My aunt gave me a hat and I lost it.
2 )两个动作相继发生,可用一般过去时;如第一个动作需要若干时间完成,用过去完成时。 When I heard the news, I was very excited.
3)叙述历史事实,可不用过去完成时,而只用一般过去时。
Our teacher told us that Columbus discovered America in 1492.

过去分词做表语
1过去分词(短语)作表语时,其作用相当于adj.,说明的是主语的状态
All the windows are broken.
All hope is gone.
He looked worried after reading the letter.
常见作表语的过去分词有:disappointed, drunk, amused, frightened, married, excited, experienced, interested, confused, pleased, puzzled, satisfied, tired, worried,gone, dressed, lost等。
注意
过去分词作表语时和动词的被动语态结构相似,但两者表达的`意思明显不同,前者说明主语的特点及所处的状态,而后者强调被动的动作。
My glasses are broken.我的眼镜碎了。(状态)
My glasses were broken by my son.我的眼镜被我儿子摔碎了。(动作)

1. 定义:用作表语的从句叫做表语从句。
2. 构成:关联词+简单句
3. 引导表语从句的关联词的`种类:
(1) 从属连词that。

(2) 从属连词whether, as, as if。
例如:He looked just as he had looked ten years before. 他看起来还与十年前一样。

例如:All this was over twenty years ago, but it's as if it was only yesterday. 这都是20多年前的事了,但宛如昨天一样。
能跟表语从句的谓语动词一般为系动词be, seem, look等。
例如: It looked as if it was going to rain. 看起来天要下雨了。
