1. 引导词关

如果从句是陈述句,引导词用that(that在口语或非正式文体中常省略);如果从句是一般疑问句,引导词用if/whether;如果从句是特殊疑问句,引导词用由疑问词转换而来的疑问代词/副词。

2. 语序关

①陈述句变为宾语从句,语序不变,即仍用陈述语序。如:

He is an honest boy. The teacher said. ?The teacher said(that)he was an honest boy.

②一般疑问句和特殊疑问句变为宾语从句,语序变为陈述语序。如:

Does he work hard? I wonder. ?I wonder if/whether he works hard.

When did he leave? I don?t know. ?I don?t know when he left.

3. 时态关

①如果主句是现在的时态,从句的时态可根据实际情况而定。如:

I have heard(that)he will come back next week.

②如果主句是过去的某种时态,那么从句的时态一定要用过去的某种时态。如:

He said(that)there were no classes yesterday.

注意:如果宾语从句表述的是客观真理、自然现象等时,不管主句是什么时态,从句都要用一般现在时。如:

He said that light travels much faster than sound.
