初中英语语法梳理和提高18 动词不定式讲解 试题 动词不定式 不定式：to + 动词原形 知识梳理：提纲挈领，抓住重点和难点！ 动词不定式的基本形式是"to + 动词原形"，有时可以不带to。动词不定式（或不定式短语）没有人称和数的变化，在句子中不能作谓语。动词不定式仍可保留动词的特点，即可以有自己的宾语和状语。动词不定式同它的宾语或状语构成不定式短语。如：to read the newspaper, to speak at the meeting 等 动词不定式具有名词、形容词和副词的特征，因此在句子中可以作主语、表语、宾语、宾语补足语、定语和状语： 句法作用 例 句 作宾语 She wanted to borrowed my radio. They began to read and write. 作状语 She went to see her grandma last Sunday . He came to give us a talk yesterday. 作宾语补足语 Lucy asked him to turn off the radio. She asked me to speak more loudly Jim told Ling Feng to go home at once . The father made his son study hard. 作定语 Have you got anything to say? I had something to eat this morning . 作主语 To learn a foreign language is not easy. 注：作主语用的动词不定式常常为 it替代，动词不定式（或短语）放在后面。例如： It is not easy to learn a foreign language. It took us three days to do the work. 动词不定式的否定形式由"not+动词不定式"构成. 如: Tell him not to be late. The policeman told the boys not to play in the street. 4) 不定式省去to的情况: 在感官动词see，watch，look at，hear， listen to，feel和使役动词make，have，let等所接的宾语中（不定式做宾语不足语），不定式应省去to。但是在被动语态中不能省。如： Let me listen to you sing the song. He watched his son play computer games. I saw him run away.------He was seen to run away. The boss make the workers work the whole night.----The workers were made to work the whole night. 5) 动词不定式和疑问词连用 动词不定式可以和疑问词what ,which, how, where, when 等连用，构成不定式短语。如： The question is when to start. I don't...
