关于宾语从句的时态问题只听说主句为一般现在时、一般过去时,宾从用什么时态.那如果主句是一般将来时呢?或者其他几种时态时,

宾语从句的时态问题

1）当主句的谓语动词是一般现在时时,其宾语从句的时态可以是任何适当的时态.所以,宾语从句的时态应根据实际情况而定.

She says (that) she works from Monday to Friday. 她说她从周一至周五上班. （从句是一般现在时）
She says (that) she will leave a message on his desk. 她说她要在他桌子上留个便条. （从句是一般将来时）
She says (that) she has never been to Mount Emei.她说她从来没有去过峨嵋山. （从句是现在完成时）

2）当主句的谓语动词的时态是一般过去时的时候,其宾语从句的时态一般要用任一适当的过去时态.

He said there were no classes yesterday afternoon. 他说昨天下午没有课. （从句是一般过去时）
He said (that) he was going to take care of the baby. 他说他会去照看这个婴儿. （从句是过去将来时）
He said (that) they were having a meeting at that time. 他说他们那时正在开会. （从句是过去进行时）

3）但是当宾语从句是表达客观真理和规律的句子时,其时态仍旧用一般现在时.eg.
The teacher told us(that) nothing is difficult if we putour hearts into it.
老师告诉我们世上无难事,只怕有心人.
