但是which在句中充当成分,一般不可以省略。
例如:I said (that)he was right
(资料图)
He asked me which was his
that引导宾语从句无意义,不充当句子成分常省略。但下列情况除外:
①.介词宾语从句的that不能省略。
He is a good studentexcept that he is a little careless
②.and连接的两个从句,两个从句的that不能省略。
He told me that he hadtwo sons and that they both had gone to college.
③.在动词+it+宾语补足语+宾语从句结构中,that不省略。
I heard it said that hehad gone abroad
We found it impossiblethat he could finish it in such a short time
that引导的宾语从句中,that在句子中不做任何成分,在口语中还常常省去,但如果从句时并列句时,第二个分句前的that就不能省略,
而which呢,引导的宾语从句相当于特殊疑问句,应注意使用陈述句语序就行
而两者区分的关键呢就是看在句中是否做句子成分
that是强调句的标志,是不能省的
It is that是强调句的固定用法:
一、如果强调句型指现在或未来情况用It is,指过去情况用It was。
二、被强调部分往往是句子的主语、宾语、时间状语和地点状语,但有时也可强调比较复杂的内容,如时间状语从句、条件状语从句、not until…、not only…but also…、…as well as…等结构。
