怎样使用动词不定式的被动语态?适用范围是什么?

  • 不定式的逻辑主语通常是句子的主语,如果不定式有自己的逻辑主语,它通常由for或of引起.

    动词不定式的一般式表示它与谓语动词同时或之后发生;其完成式则表示发生在谓语动词之前的动作.但要注意动词:plan, expect, intend, wish, mean, want, suppose, would (should)like等后面的不定式完成式则表示原打算要做而最终未做成的事情.

    当不定式的逻辑主语是动作的承受者时,这个不定式要用被动式,包括它的一般式和完成式

    动词make, let, hear, watch, see, feel, help等后面做宾语补足语的不定时一般不带to,如:

    The strange thing made me feel thirsty. 这个奇怪的东西是我感到口渴.

    I heard her move about in her room upstairs last night.

    昨晚我听到他在楼上房间里走来走去.

    Did you see Jack take away the magazine? 你看到Jack拿走了那本杂志了吗?

    当以上所列的谓语动词改为被动语态时,后面的不定式需带to.如:

    He was heard to move about in her room upstairs last night.

    昨晚听到他在她的房间里走来走去.

    Was Jack seen to take away the magazine? 诱人看到 Jack拿走了那本杂志了吗?

    (let, feel和少用于被动语态)
