例如:If the snow has completely stopped, we will be playing with snow on the playground.如果雪能够完全停下来,我们将正在操场上玩雪呢!If it is snowing, we will have been walking in the snow for more than two hours.如果天一直在下雪,我们将在雪地里走了两个多小时了。

即主句是一般将来时,从句用一般现在时;主句用过去将来时,从句用一般过去时;当主句中有can/can’t 的话,则从句用一般现在时。
例如:If he has time, he will come tomorrow.If she finishes early, she can come back early.If you don’t do homework, the teacher will scold you.第二种用法:1.if从句还表示不可实现的条件或根本不可能存在的条件,也就是一种虚拟的条件或假设,从句多用一般过去时或过去完成时。

英语主将从现的用法
英语主将从现的用法主将从现是英语中一个非常常见的语法现象,它是指在时间状语从句和条件状语从句中,用现在时态代替将来时态的用法。
也就是说,I.如果从句的表意是一般将来时,就要用一般现在时代替;II.如果从句表意是将来进行时,就要用现在进行时代替;III.如果从句表意是将来完成时,就要用现在完成时代替。
本文通过主将从现在时间状语从句和条件状语从句中的用法,分别详解主将从现的实际运用。
一、条件状语从句中的主将从现(常见引导词有if、unless、as long as)例句1:You will regret it if you don't follow my words. 如果你不按我说的做,你会后悔的。
注释:主句中用的是一般将来时,从句本来也应该是用一般将来时。
但是,在条件状语从句中用一般现在时(if you don't follow)代替一般将来时(if you will not follow)。
例句2:I will call you, but you don't have to answer my phone unless you are not having a class. 我会给你打电话,但是除非你到时候不在上课,否则你就不用接电话。
注释:从整个句子的时间来看,从句本应该是将来进行时。
由于是在条件状语从句中,所以用现在进行时(unless you are not having)代替将来进行时(unless you will not be having)。
例句3:As long as we have completed the task by the end of next month, we will certainly be praised. 只要我们再下个月底前完成这个任务,我们肯定会被表扬。
注释:从条件状语从句的时间状语"by the end of next month"可以看出这里本来应该用将来完成时。

二、如果主句是祈使句,那么从句通常要用一般现在时如:Don’t laugh at me when I make a mistake.我犯错误的时候不要笑话我。
三、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如:You should be quiet when you are in the reading room在阅览室时应保持安静。

例如:I will tell him about it when he comes.If it is fine tomorrow, we will go outing.六、如果主句的时态是过去将来时,那么从句要用一般过去时。

主将从现常见的有以下六种情况
一、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。
二、如果主句是祈使句,那么从句通常要用一般现在时如:Don' t laugh at me when I make a mistake.我犯错误的时候不要笑话我。
三、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如:You should be quiet when you are in the reading room在阅览室时应保持xx。
四、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notto....如;She said not to close the window常见的时间状语从句的连词有:as soon as,when,while ,as,until 等五、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.六、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.I knew he could help me if he was free the next day.主要标志有:if、unless、until、when、as soon as等If引导的条件句(if翻译成"如果"的时候)I .(if从句)主句v./ v.三单will+v.If you ask him, he will help you.如果你请他帮忙,他会帮你的。
