1.if 条件从句的谓语动词用虚拟语气，主句也要用虚拟语气

1〉表示与现在事实相反 2〉表示与过去事实相反 3〉表示与将来事实相反

从书上抄来的，希望能有助于大家的理解
1>与现在事实相反的假设
    从句谓语动词were/V.+-ed（过去式），主句谓语动词 should （would，could，might）+ V.
   eg. If I were you, I would take an umbrella.
         If I knew his telephone number, I would tell you.

2>与过去事实相反的假设
   从句谓语动词had+V.+-ed，主句谓语动词 should （would，could，might）+have+V.+-ed
   eg.If he had taken my advice, he would not have made such a mistake.

3>与将来的事实相反或完全不可能实现的事
   从句谓语动词should+V./were to+V.，主句谓语动词should （would，could，might）+V.
   eg.If he should come here tomorrow, I would talk to him.
        If she were to be there next Monday, I would tell her about the matter.

It is possible that Native Americans originally have migrated to the Western Hemisphere over a bridge of land that once existed between Siberia and Alaska.





(A) have migrated to the Western Hemisphere over a bridge of land that once existed





(B)  were migrating to the Western Hemisphere over a bridge of land that existed once



(C) migrated over a bridge of land to the Western Hemisphere that once existed





(D)migrated to the Western Hemisphere over a bridge of land that once existed





(E) were migrating to the Western Hemisphere over a bridge of land existing once


这道题选D ， 为什么 不用虚拟语气？ 这里 possible 不也是表一中各可能性 推测。
