英语语法句式学习_动词句式 be said + 不定式

  这是一个重要的句式,常常出现在非谓语动词的考查中。其特点是,可以转换成用it作形式主语,用that从句作实际主语。不定式可以是一般式,也可以是完成式。

  例如:

  The yeti is said to be a huge hairy animal. = It is said that the yeti is a huge hairy animal. 据说(喜马拉雅)雪人是一种巨大的多毛动物。

  可以用于这个句式的动词有:report, think, believe, suppose, consider, expect, require, predict 等。

  再如:

  Everyone is expected to be here on time. = It is expected that everyone should be here on time.

  Mr. Benet is believed to have a large farm on the east coast. = It is believed that Mr. Benet has a large farm on the east coast.

  Thomas was considered to be one of the top students in his class. = It is considered that Thomas is one of the top students in his class.

  需要注意的是:“be said +不定式”中的不定式,若是一般式,不定式动作与be said同时存在、或晚于be said发生;若不定式是完成式,则不定式动作先于be said发生。

  例如:

  China is said to have sent three manned spacecraft into space. (据人们”现在“说,中国”此前“已经发送了三艘载人飞船。)

  Loulan is believed to have been gradually covered by sandstorms. (人们”现在“相信楼兰”过去“为沙尘暴所淹没。)

  You are required to write a poem and read it before the club members. (所要求的动作有待完成。”要求“在先。)
