卫生类复习笔记:强调句结构
常见的强调句结构是it 引导的句子。
It is (was) 被强调部分 that (who) 句子其他部分。
此结构强调的成分仅限于主语，宾语和状语。
It is from the sun that we get light and heat.
It was not until I had read your letter that I understood the true state of affairs.
使用此句型时， 应注意以下几点。
(1) 一般情况用It is(was)……that…如:
He read three books in the library yesterday.
我们分别可以强调主语、宾语、地点状语和时间状语。如:
It was he who(that)read three books in the library yesterday. (强调主语)
It was three books that he read in the library yesterday. (强调宾语)
It was in the library that he read three books yesterday. (强调时间状语)
(2) 当被强调部分指人时， 可用that， 也可用who; 指物时， 只用that， 如:
It was Tom who(that)I met last week.
It is a new boke that his brother wants to buy.
