強(qiáng)調(diào)句that是一個(gè)不完整的句子.因?yàn)榫渲斜粡?qiáng)調(diào)的部分已放在了前面.而主語(yǔ)從句that之后是一個(gè)完整的句子.如
It is an honour that I have been invited to the ball.這句是主語(yǔ)從句
It is a book that I bought on my way home yesterday.這句是強(qiáng)調(diào)句,再有主語(yǔ)從句的主句除有名詞作表語(yǔ)外還可有形容詞,過(guò)去分詞等.而強(qiáng)調(diào)句沒(méi)有.因?yàn)閺?qiáng)調(diào)句不對(duì)形容詞強(qiáng)調(diào).
如下面這兩句都是主語(yǔ)從句.
It is said that Tom is writing a book.
It is clear that he is satisfied with my work.
