It is/was .that 句型,在be动词后如果跟的是名词和名词词组就是定语从句吗 如果是介词和短语和副词?
那It was the policeman who found my lost bike in a small village 这是定语从句还是强调句? 大伙帮个忙,帮我总结在强调句和定语从句的区别
It was the policeman who found my lost bike in a small village.首先肯定这是个强调句型,原句是 The policeman found my lost bike in a small village.被强调部分是主语 the policeman;强调句型在强调主语和宾语时,从句与定语从句结构几乎无差别,但 it 是强调句型的明显标志;在强调状语时,差别就较明显,例如:
1、It was nine o'clock when he appeared suddenly(定语从句 when = at which,it 指时间)
2、It was at nine o'clock that he appeared suddenly(强调句型,可还原成:He appeared suddenly at nine o'clock);
希望已经讲清楚了,仍有疑问,欢迎追问!
再问: 强调句中,前后的时态需不需要一致?It is Mary who wrote this book 这句话中,为什么be动词和后边的wrote 不是同一个时态呢?
再答: 强调句中,时态应该一致,除非表示过去到现在任然是事实的一件事情,就像您的例句
再问: 那像It be ....when/where ; It be /has been...since; It be ...before 这些是什么句型啊?应该不是强调句吧?
再答: 比如吧:It is three years since he joined the army。这句话我们一看就知道 It 表示时间(three years),就不可能是强调句型。在强调句型中,it 只是个虚词,没有实际意义,只起搭起句子结构作用。
