主将从现怎么用在什么情况下?
1.如果主句是将来时或表示将来含义时，那么条件和时间状语从句多用一般现在时。例如：
When I grow up,I will be a nurse and look after patients/I want to be a nurse and look after patients. 我长大后要当一名护士，照顾病人。
2.如果主句是祈使句，那么从句通常要用一般现在时。例如：
Don’t laugh at me when I make a mistake. 我犯错误的时候不要笑话我。
3.如果主句是含有情态动词的一般现在时，根据需要从句多用一般现在时。例如：
You should be quiet when you are in the reading room. 在阅览室时应保持安静。
4.如果if的条件状语从句遇到变换间接和直接时，祈使句应用not to....，例如：
"Don'tclose the window if the rain stops,"she said.→She said not to close the window if the rain stops.
5.主将从现说的是在含有时间状语从句和条件状语从句的主从复合句中，如果主句的时态是一般将来时，那么从句要用一般现在时。例如：
If it is fine tomorrow, we will go outing. 如果明天天气好，我们就去郊游。
6.如果主句的时态是过去将来时，那么从句要用一般过去时。例如：
He said that he would have another try if he had the chance. 他说如果有机会他会再试一次。
