公开课课件动词不定式的用法
05
动词不定式与其他非谓语动词比较
与动名词比较
动词不定式和动名词在句子中都可以充当主语、宾语等成分，但它们的意义和用法 有所不同。
动词不定式表示具体的、一次性的动作，而动名词则表示抽象的、习பைடு நூலகம்性的动作。
在某些情况下，动词不定式和动名词可以互换使用，但表达的含义可能有所不同。
与现在分词比较
动词不定式和现在分词都可以表示主 动的动作，但它们的时态和语态有所 不同。
在某些情况下，动词不定式和现在分 词可以互换使用，但需要根据具体语 境来判断。
动词不定式不受时态限制，可以表示 过去、现在或将来的动作，而现在分 词则通常表示正在进行的动作。
与过去分词比较
动词不定式和过去分词都可以表示被动的动作，但它们的用法和意义有 所不同。
动词不定式表示被动的动作时，需要使用助动词be的适当形式，而过去 分词则可以直接表示被动的动作。
03
动词不定式在句子中作用
作主语
01
动词不定式作主语时，谓语动词 用单数形式。
02
常用it作形式主语，把真正的主语 动词不定式置于句后。
作宾语
能够接动词不定式作宾语的有ask, agree, beg, decide, determine等 。
动词不定式与名词等构成复合宾语时 ，通常要用it作形式宾语，而把真正的 宾语动词不定式置于句后。
择合适的动词形式。例如，正确的表达是 “I enjoy listening to music”，而不是
“I enjoy to listen to music”。
逻辑主语问题
要点一
不定式逻辑主语与句子主语不一 致
动词不定式的逻辑主语应与句子主语保持一致。例如，正 确的表达是“It is important for you to study hard”， 而不是“It is important for him to study hard”。
