初中英语语法知识归纳:动词时态的一致
时态的一致
时态的一致主要是指在主从复合句中,主句与从句之间的时态一致通常主句的时态决定从句的时态。原则是:当主句是现在时与将来时,从句的谓语根据具体情况可以使用任何时态。但是,当主句谓语使用过去时,从句必须使用过去时态。如下表:
难点
1、宾语从句和间接引语与主句的时态一致,符合上述原则。但如果宾语从句表示客观事实和真理,即使主句谓语用过去时,从句的谓语也应该使用一般现在时:如:
Our teacher told us a little knowledge is dangerous
我们老师告诉我们一知半解是危险的。
He said that light travels faster than sound.
他说光传播速度比声音快。
2、有些形容词后可以跟从句,这种从句常看成宾语从句,它的主、从句时态也符合上述原则。这些形容词有:afraid, glad, sure, sorry, certain, aware, confident, delighted, lucky, surprised, worried。如:
I’m sure that he will succeed.
3、主语从句、表语从句、同位语从句也要与主句的时态一致。如:
That is why he was late for school.
