有那些从句需要和主句的时态一致？

主从句时态一致原则是指：1.如果主句是一般现在时态或现在完成时态，从句常根据需要选择适当时态。 如：The teacher says that he will go to the Great Wall next week . He tells us that he had an accident the other day .2.如果主句是一般过去时态，从句常用过去的某种时态；但从句如果是客观的真理或事实，仍用一般现在时态表达。如：He said that he would go to visit the Great Wall the next week . The teacher told us that the sun rises in the east .

一般从句都是的
但是也有特殊比如
条件状语从句和时间状语从句用一般时态 表示将来
I will call as soon as he comes
we will not go out if it rains tomorrow
