英语强调句通过特定的语法结构强调句子成分,基本结构为:It is/was + 被强调的部分 + that/who/whom/whose/when/where等疑问词 + 其余部分。如果被强调的部分是可数名词的复数形式,应使用复数形式的关系词“those”。被强调的部分通常放在句子的开头或结尾,不能放在中间。掌握这种语法结构对于提高英语表达能力是非常有帮助的。
英语强调句的基本结构为:It is/was + 被强调的部分 + that/who/whom/whose/when/where等疑问词 + 其余部分。例如:It was the book that I wanted to read.(正常语序:I wanted to read the book.)这句话中,被强调的部分是“the book”,而“that”是引导从句的关系词。
在强调句句型中,如果被强调的部分是可数名词的复数形式,那么就需要使用复数形式的关系词“those”,例如:It was those books that I wanted to read.(正常语序:I wanted to read those books.)
当然,也可以使用其他关系词,例如“who”、“whom”等,具体要根据被强调的成分来决定。例如:It was those teachers who helped me a lot.(正常语序:Those teachers helped me a lot.)
需要注意的是,在强调句中,被强调的部分通常放在句子的开头或结尾,而不能放在中间。例如,以下两种说法都是不正确的:
It was I who yesterday went to the bookstore.
It was those books I wanted to read.
正确的说法应该是:
It was I who went to the bookstore yesterday.
It was those books that I wanted to read.
