学习英语，口语是很重要的，但是学习英语语法也是很重要的，只有学好了语法才能够更好的去说，那么新航道英语小编老师就在这里为大家分享一下动词句式be said+不定式的语法吧。
这是一个非常重要的句式，经常出现在非谓语动词的考查当中。其特点就是，可转换成为用it作形式主语，用that从句作实际主语。不定式能够是一般式，也能是完成式。
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)雪人是一种非常巨大的多毛动物。
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.
需要大家注意的就是：“be said +不定式”中的不定式，如果是一般式，不定式动作和be said同时存在、或者是晚于be said发生;如果不定式是完成式，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。)
成人英语语法的学习是很重要的，有些人积累了很多的单词量，但是不知道语法这也是很难够将英语说出口的，所以大家要多多的了解一下语法。
