八年级上册动词不定式用法总结及练习 M5-6 动词不定式即to+动词原形，否定形式是：not to +动词原形动词不定式在句中不能作谓语，可以充当其他句子成分动词不定式没有人称和数的变化同学们在八年级上册书中学习的是动词不定式作宾语、目的状语和宾语补足语的用法下面做详细解说： 一：动词不定式作宾语 同学们在学习英语过程中会遇到两个动词连用的情况，比如要表达“想做某事，需要做某事，决定做某事”时，第一个动词往往在句中体现句子的时态，即谓语动词，但是后面的动词该用什么形式呢？这就需要用到动词不定式了如：want to do sth. , need to do sth. , decide to do sth. 像want，need，decide等动词后面可以直接加动词不定式，那么这个动词不定式就作前面动词的宾语这类动词属于及物动词（就是能够直接加名词代词作宾语的动词），表明想要，计划或希望要做（或发生）的事动词不定式所表示的多为将来的行为但需要注意的是:在英语学习中并不是所有的动词都采用“动词+不定式”的形式，因为动词不同，对其后的形式要求也不同常见的后面接“to +动词原形”作宾语的动词有：plan计划，decide决定，want想要，hope希望，offer提议，learn 学习，promise承诺，agree同意，等等。
