就近原则 英语 第一个为什么用were 第二个句子 近哪个 如果是就远原则 远哪个 举例

第一个是疑问句，谓语动词在主语前面，两个并列的主语you和he里，you在前面，和谓语动词最近，所以谓语动词be按照you的使用规则，采用were的形式。
第二个是陈述句，谓语动词在主语后面，两个并列的主语his parents和he，he在后面，离谓语动词最近，所以谓语动词be按照he（单数第三人称），用is的形式。
清楚了吗？就是在两个或更多的并列主语里，看谓语动词离哪个主语最近，就按哪个变化。

就近原则 就是离靠近的一个主语 最近。
由于第一个句子是一般疑问句， 那么靠近谓语的主语是 you .
第二句是陈述句 ， 谓语靠近主语的的是he .

在陈述句中， 就远原则 是 指 的离谓语 较远的主语， 也就是第一个主语
eg . He is as well as I is a student .

你是云浮的吗

这句话里包含了虚拟条件句,如果不倒装就是:The acrobat had to acknowledge he could very well die if he were to perform it.
虚拟条件句的从句部分含有were, should, 或had时, 可省略if，再把were, should或had 移到从句的句首，实行倒装。例如：
Were they here now, they could help us. =If they were here now, they could help us.他们现在在的话，就会帮助我们了。
Had you come earlier, you would have met him. =If you had come earlier, you would have met him.你来得早一点，就碰到他了。
Should it rain, the crops would be saved. =Were it to rain, the crops would be saved.假如下雨，庄稼就有救了。
注意：在虚拟语气的从句中，动词'be'的过去时态一律用"were"，不用was，即在从句中be用were代替。例如：
If I were you, I would go to look for him. 如果我是你，就会去找他。
If he were here, everything would be all right. 如果他在这儿，一切都会好的。
