如果从句是一个客观真理？
1、当从句是陈述句时，从句用that引导，在非正式问题中可省略。
I think (that) you shoud tell the truth.
我认为你应该说实话。
2、当从句是疑问句时，从句用whether、if引导，且从句为陈述句语序。
He asked whether/if he could go out to play with his friends.
他问他是否可以和朋友出去玩。
3、特殊疑问词引导的宾语从句，特殊疑问词有who、whom、whose、what、which、when、where、why、how等，且从句为陈述句语序。
She asked who we would go to the zoo with.
她问我们将会和谁一块去动物园。
当主句为过去时
①从句用一般过去时或过去进行时表示与主句谓语动词动作同时发生；
②从句过去完成时表示该动作发生在主句谓语动作之前；
③从句谓语用过去将来时表示该动作发生在主句谓语动作之后；
④如果从句是一个客观真理，那么从句的时态不根据主句的时态而变化；
⑤当宾语从句的引导词是who、whom、whose、what、which、when、where、why等表疑问时，不能按正常语序安排，经常将这类引导词置于句首。
