请问:they did not do what they are doing.前边是过去时,从句用现在时吗?
Answer:
从句绝对不能用现在时.
全句译:
他们当时没有做他们现在正在做的事.
可以看出完全不符合逻辑.(现在做的事,当时怎么会知道做没做?)
此句应改为:
They did not do what they were doing .
小结:当主句时态为过去时,宾语从句要用"过去"的相应时态.
补充问题回复:书是人写的,是人难免就会犯错误.尽信书不如无书,要学会对
不对的地方做出自信的怀疑及正确的判断.
If you still feel confused,leave a message please

要根据意思了,我开始认为主句是什么时态,从句就要保持一致
但是看过几个句子却不是这样的,有的是主语用过去时从句用现代时,有的是用具用现代时从句用过去时,总之什么请款都出现过,具体句子我现在不太好找了

从句要与主句时态一致。。。用过去进行时
They did not do what they were doing.

所说一般来说:当主句时态为过去时,宾语从句要用"过去"的相应时态.
但在一些特定语境中也有例外,这句话的意思是:他们过去从没做过现在他们正在做的事情!
