八年级动词不定式的知识点 【篇一：八年级动词不定式的知识点】 作为初中三年中承上启下的一年，对学生和家长来说都至关重要。 为帮助初二的同学们能够更好地掌握相关知识，特别整理《大全： 动词不定式用法详解》，希望对大家有所帮助。 尽管动词不定式用法灵活多样;尽管有些动词或短语后面既可以接to do 又可以接 doing ，但只要我们用心观察，发现还是可以找到规律的。与其说是动词不定式，到还不如说是动词“定式”。因为我们可 以大体上把它分为三类形式,即: do / to do / doing 动词不定式没有人称和数的变化，在句中不能独立作谓语,是非谓语 形式的一种。但动词不定式具有名词、形容词和副词特征，在句中 可以作主语、宾语、宾语补足语、定语、表语和状语等多种成分。 另外，动词不定式具有动词特点，可以有自己的宾语和状语，组成 动词不定式短语。动词不定式的肯定形式是 to+do;其否定形式是 not to+do。 下面以动词不定式在句中的作用来予以详细说明,希望同学们从中找 到规律，下次fox嘉洲来和你一起讨论并解决问题。 1.作主语 可以直接作主语。如： to see is to believe. 但在英语中，常用it作形式主语，真正的主语即动词不定式放在后面。如： it s wrong to play tricks on other people. it s our duty to keep our environment clean and tidy. 点击规律：动词不定式在句中作主语时，常放在it is +adj.(形容 词)+to do sth.或 it is +n.(名词)+to do sth.句型中，it仅作形式主语。 2.作宾语 a.want，decide ，agree等动词后面跟并且只能跟不定式。如： we agreed to start early. she wants to be a doctor. b.love，like ，begin，start，hate ，prefer等词后面可以接不定式。 点击规律：上述动词后面除接不定式外，还可以接动名词，意思无 很大区别。

2. 动词不定式作表语 动词不定式作表语时作为形容词，并与be动词连用，例如： His dream is to be a doctor. 他的梦想是成为一名医生。 四、作为副词 1. 目的状语 动词不定式作目的状语表示主语动作的目的或者原因，位于谓语动词之后，例如： I went to the supermarket to buy some fruits. 我去超市买水果了。

初二年级英语动词不定式讲义和对应练习 动词不定式是由“不定式符号to+动词原形”构成的一种非谓语动词结构。有些动词不定式不带to，动词不定式可以作句子的主语、表语、宾语、定语、补语、状语或单独使用。一、用作主语 直接把动词不定式置于句首的情况不多，多数情况用it作形式主语，把真正的主语——动词不定式置于句末，特别是不定式短语较长时(有时在不定式的前面还会用for sb.表示不定式的逻辑主语)。动词不定式作主语，谓语动词用第三人称单数形式。带疑问词的不定式短语作主语常置于句首，复合不定式结构作主语常置于句末。如： 1、把不定式置于句首。如： To get there by bike will take us half an hour. 2、用it作形式主语，把真正的主语不定式置于句后，常用于下列句式中。如： ①It＋be＋名词＋to do It's our duty to take good care of the old. ②It takes sb + some time +to do How long did it take you to finish the work? ③It＋be＋形容词＋for sb＋to do 逻辑主语 It is difficult for us to finish writing the composition a quarter of an hour. ④It＋be＋形容词＋of sb＋to do “It is stupid of you to write down everything”，the teacher says. 注意：在③中，常用表示客观情况的形容词，如：difficult, easy, hard, important, impossible, necessary 等；在④中，常用careless, clever, good, foolish, honest, kind, lazy, nice, right, silly, stupid, wise等表示赞扬或批评的词，强调对人的评价。在不定式前的sb，可看作其逻辑主语。这一句式有时相当于Sb is＋形容词＋to do句式，如：It's kind of you to help me with my English.=You are kind to help me with my English. ⑤It seems(appears)＋形容词＋to do It seemed impossible to save money. 3、带疑问词的不定式短语作主语 How to solve the problem is hard for him. 二、用作表语 动词不定式作表语，常说明主语的内容、性质、特征，通常放在连系动词（主要是be动词）后。如： 1.The best way to improve your English is to join an English club. 2.The first thing is to greet the teacher. 注意：不定式作表语表示具体动作或将来动作；动名词作表语表示抽象的一般行为。 Our work is serving the people. 三、用作宾语 1.可以接带to的动词不定式作宾语的动词主要有：要求、选择、同意(ask, choose, agree)，期望、决定、学习(expect, hope, decide, learn)，宁可、假装、知道(prefer, pretend, know)，希望、想要、愿意(wish, want, would like / love)。如： 1)We decided to talk to some students about why they go there. 2)He prefers to eat white bread and rice. 3)I’d love to visit Mexico 2.动词decide, know, learn, show, teach, tell...，介词结构on...可用疑问词带to的不定式短语作宾语，但why后面的不定式不带to。如：
