every time 与every day 区别.every time 可引导句子?
“One of the great lessons of taking part in TV-Turnoff Week is the realization that_____ I turn on the TV,I’m deciding not to do something else,” Vespe said.
A every day B every time
注解说every day后面要加when,为什么every time 不用,every day用?

答案

1.原因很简单,因为every day只是一个副词短语,在句中只能做状语,它不是连词,不能引导时间状语从句,所以后面必须还要用when来引导I turn on the TV这个时间状语从句.
2.而every time不但可以做副词单独做状语,翻译为“每一次”；
而且它还可以充当连词,引导时间状语从句,意思是“每一次...的时候”,所以这时它后面无须再加连词when.
如：I saw her parents every time I went to visit her.
每一次我去拜访她的时候,我都看见了她的父母亲.
