4.判断强调句的方法 判断一个句子是否是强调句,可把“It is/was”和“who/that”去掉,剩 余部分如果是一个完整的句子,那么这个句子是强调句,否则不是。 试比较下列句子,判断是强调句还是其他句型。 ①It was you and Tom that didn’t come yesterday. 句型:强调句 分析:去掉“It was”和“that”后,句子变成“You and Tom didn’t come yesterday.”结构完整,所以是强调句。 ②It is strange that they didn’t come yesterday. 句型:主语从句 分析:去掉“It is”和“that”后,句子不完整,所以不是强调句。本句 中It作形式主语,that引导真正的主语从句。
