1、 初三英语重点知识点的归纳5篇 动词不定式 一。 定义: 由to+动词原形构成。不定式是一种非限定性动词。而非限定动词是指那些在句中不能单独充当谓语的动词,可分为不定式,动名词,现在分词和过去分词。“动词不定式”由动词+不定式构成。动词不定式在句中可以作句子除谓语之外的任何句子成分。动词不定式的被动形式除了一般形式外还有其完成式和进展式。 二。 动词不定式的构成:to+动词原形 (1)作主语 动词不定式作主语时,句子的谓语动词常用单数,其位置有以下两种: (1)把不定式置于句首。 如:To get there by bike will take us half an hour. (2)用it作
2、形式主语,把真正的主语不定式置于句后,常用于以下句式中。 如: It+be+名词+to do Its our duty to take good care of the old. It takes sb+some time+to do How long did it take you to finish the work? It+be+形容词+for sb+to do It is difficult for us to finish writing the composition in a quarter of an hour. It+be+形容词+of sb+to do It is stup
3、id of you to write down everything (that) the teacher says. It seems(appears)+形容词+to do It seemed impossible to save money. 在句型中,常用表示客观状况的形容词,如:difficult,easy,hard,important,impossible,necessary 等; 在句型中,常用careless,clever,good,foolish,honest,kind,lazy,nice,right,silly,stupid,wise等 表示赞扬或批判的词。 在不定式前的sb
4、,可看作其规律主语。这一句式有时相当于Sb is+形容词+to do句式 ,如:Its kind of you to help me with my English.=You are kind to helpme with my English. (3)举例 (1) Its easy (for me) to do that.我做这事太简单了 easy,difficult,hard,important,possible,impossible,comfortable,necessary,better; the first,the next,the last,the best,too much,to
5、o little,not enough 1、Its so nice to hear your voice. 听到你的声音真快乐。 2、Its necessary for you to lock the car when you do not use it. 当你不用车的时候,锁车是有必要的。 (2) Its very kind of him to help us.他帮忙我们,他真好。 Kind,nice,stupid,rude,clever,foolish,thoughtful,thoughtless,brave,considerate(考虑周到的),silly,selfish(自私的) 例句
6、: 1、It was silly of us to believe him.我们真愚蠢,竟然信任了他。 2、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。 留意: (1) 其他系动词如,look,appear等也可用于此句型 (2) 不定式作为句子成分时,动词用单数形式。 (3) 当不定式作主语的句子中又有一个不定式作表语时,不能用It is to的句型 (对)To see is to believe.眼见为实。 (错)It is to believe to see. 三。 动词不定式作宾语 后面能接不
7、定式作宾语的动词有:agree, ask, choose, decide, forget, hope, learn, want, wish, would like等。 1、We hope to get there before dark. 我们盼望天黑以前到那儿。 2、The man decided to do it herself. 那个男人打算自己做那件事。 动词不定式作宾语的留意事项(2点) 1. 有些动词既可跟不定式作宾语,也可跟动名词作宾语,但含义不同: remember to do 记住要做某事 remember doing 记得曾经做过某事 forget to do遗忘要做某事
8、forget doing 遗忘曾经做过某事 stop to do 停下来去做某事 stop doing 停顿做某事 go on to do 连续做另一件事 go on doing 连续做原来在做的事 2. 不定式作宾语时,如带有宾语补足语,则要把不定式放到后面,用it作形式宾语,构成“主语+动词+it+宾补(形容词、名词)+不定式”构造。 如:He found it very difficult to get to sleep.他发觉很难入睡。 初三英语重点学问点的归纳 篇二 初三英语语法学问 一。 介词by的用法 1、 意为“在旁”,“靠近”。 Some are singing and da
