  在英语的表达式中,动词不定式是在英语表达中的一种非谓语动词形式,而动词不定式是指动词的一种不带词形变化从而不指示人称、数量、时态的形式。针对于动词不定式,下面小编就为大家带来动词不定式的用法

 

  一、动词+不定式;动词+宾语+不定式

  I like to keep everything tidy. 我喜欢每件东西都保持整洁。

  I like you to keep everything tidy. 我喜欢你使每件东西都保持整洁。

  I want to speak to Tom.  我想和汤姆谈话。

  I want you to speak to Tom.  我想让你和汤姆谈话。

  二、不定式的用法

  三、动词不定式的例子

  做主语·

  To be a doctor is hard. 做医生很难。

  · To learn English well is not easy. 学好英语不容易。

  · To say is to believe.眼见为实。

  动词不定式(短语) 做主语时,为了避免句子的头重脚轻,可以用“it”作形式主语,而把真正的主语--动词不定式(短语)放在句子的后部。

  上面的句子可以改为:

  · It is hard to be a doctor. ·

  It is not easy to learn English well. ·

  It’s important to plant trees in spring.

  如果动词不定式的动作是谁做的,可以在动词不定式前面加一个由介词for引导的短语,称为不定式的复合结构。

  · It’s good for us to read English aloud in the morning. 对我们来说每天早晨大声读英语是很有益的。

  · It is important for students to use English every day. 对学生来说每天使用英语是很重要的。

  四、不定式的时态和语态

  以上就是动词不定式的用法,希望大家在学习英语不定式的时候,可以认真的把英语语法中的动词不定式学习好,这样下来,英语的学习成绩才会进步。
