宾语从句的三句话（宾语从句十二个字口诀）

宾语从句时态考点归纳为三句话：主过，从过；主不过，从随意；从真理，一般现在永不变。
1. 主不过，从随意：当主句不是过去时的时候，从句该用什么时态就用什么时态，不受限制。
He tells me that he was back yesterday.

I wonder if you will come next year.

2.主过，从过：当主句是过去时的时候，从句要改为过去的对应时态，如：I know you're right.当主句变为过去时的时候，从句要把are改为were，即I knew you were right.

I really wanted to know what you had done.

I saw he was playing basketball.
3.从真理，一般现在永不变：当从句是客观真理的时候，无论主句是什么时态，从句一律用一般现在时，如：My mom told that Beijing is the capital of China.
