英语中 主将从现和虚拟语气有什么联系?有什么区别?复制党都切腹去 最好说点自己的想法
与虚拟语气无关.主将从现只用于时间状语从句和条件句.
1.时间状语从句：明天他来时,我会告诉他的.I will tell him when he comes tomorrow.
2.条件句：如果明天下雨,我们就呆在家里.If it rains tomorrow,we will stay at home.
虚拟语气属于条件句.而真实的条件句都必须用陈述语气.（比如上一句）
虚拟语气基本上分三种时间段：
1 对过去发生完的事情,埋怨,或猜测.如：如果你不去那里的话,就不会发生这事情了.
If you had not gone there,it would not have happened.
2.对现在的推测,如：如果我是你的话,我就去那里.If I were you,I would go there.
3.对未来推测,如：如果明天地球没有水的话,我们怎么办?What should we do if there should no water on the earth tomorrow?

在复合句中，由when ,as soon as ,after ,before ,until , unless等引导的时间状语从句和由if 引导的条件状语从句，都符合“主将从现”的原则，即主句是一般将来时（或用一般现在时表示一般将来时的意义），从句要用一般现在时。这是历年中考的考查热点。 ①一般将来时 ②一般现在时

虚拟语气：
一、与现在事实相反
若与现在事实相反，虚拟语气的条件从句的谓语用过去式(be通常用were)，主句谓语用“should (would, could, might)+动词原形”。如：
If you took a taxi，you'd get there quicker. 如果你坐出租车去，你可以快一点到那里。(但你不坐)
If I knew her number I could ring her up. 要是我知道她的电话号码，我就可以给她打电话了。(可惜我不知道)
二、与过去事实相反
若与过去事实相反，虚拟语气的条件从句的谓语用过去完成时(had+过去分词)，主句谓语用“should (would, could, might)+have+过去分词”。如：
If I'd left sooner，I'd have been on time. 要是我早点动身，我就准时到了。(但我动身太迟了)
If we had found him earlier we could have saved his life. 要是我们当时早点找到他的话，我们就可以救活他。(可惜我们找到他太晚了)
三、与将来事实相反
若与将来事实相反，条件从句的谓语用过去式(be通常用were)，主句谓语用“should (would, could, might)+动词原形”。如：
If he went，would you go too? 如果他去，你也去吗?(大概他不会去)
If I asked him，I'm sure he'd help us. 如果我向他提出要求，肯定他会帮助我们。(不过我不打算这样做)
注意与说明：对于与将来事实相反的情形，请注意以下几点：
一是这里说的与将来事实相反，实为对将来情况的推测；
二是此用法中的条件从句谓语除用过去式外，有时也用“should+动词原形”(表示可能性极小，常译为“万一”)或“were to+动词原形”(表示与将来事实相反的假设)；
三是当条件从句使用“should+动词原形”这样的谓语时，主句谓语除可用“should (would, could, might)+动词原形”这样的虚拟语气外，也可用陈述语气或祈使语气。如：
I should see him, I'll tell him. 万一我见到他，我就告诉他。
If it should rain tomorrow, don’t expect me. 万一明天下雨，就别等我了
