It was my brother that read three books in the library.
这句话是强调句强调主语,那可不可以按定语从句理解呢“这是我在图书馆读了三本书的表弟”?
强调主语的强调句和定语从句又该如何区分呢?
It was my brother that read three books in the library.
(1)去掉句中的 It was 和 that 后,剩下的所有单词可以可以组成一个完整的句子:
My brother read three books in the library.
(2)如果先行词是形容词性物主代词修饰的名词,后面只能用非限制性定语从句。
所以,原句只能是一个强调句。
