8.I'd feel that way too if I were you.

四级词汇讲解:

if引导的条件状语从句if I were you采用的是虚拟语气，表示与现在事实相反的假设，意为“如果我是你”，该表达在口语中很常用。需特别注意的是，即使该从句的主语为I，其对应的系动词也应为were，而非was。主句采用了情态动词would，同样表示一种假设的情况。

英语四级考点归纳:

在口语中if引导的条件状语从句运用虚拟语气一般有以下几种情况:

※ 表示与现在事实相反的假设，从句采用一般过去时，主句谓语部分为would/should+动词原形。
如:If they were here, they would help us.他们要是在这儿的话就会帮我们。

※ 表示与过去事实相反的瑕没，从句采用过去完成时had done,主句谓语部分为should/would+have done。
如:If you had worked harder, you would have succeeded.你要是再努力一些就会成功了。
If you had come yesterday, I should have told you about it.要是你昨天来了，我就会告诉你。

※ 表示对将来情况的假设，从句可采用一般过去时、were+不定式、should+动词原形，主句谓语部分为should/would+动词原形。
如:If you succeeded/were to succeed/should succeed，everything would be all right.你要是成功了，一切都会变好的。
