这两题都是考倒装句
第一次选C (倒装把主语谓语倒过来就行)
第二选B 选A和B区别在于:时态不同.A是现在完成时,B是过去时.而现在完成时强调完成的动作.过去时没有强调,只是说事情发生了.你想想done(作了)have done(已经作了)就知道了.
第二题选B是因为时态要一致.朗朗played 是过去式,很少看到过象他这么和天赋的孩子中的see和play应发生在同一时间,所以选B
句意:朗朗年轻是钢琴弹得和好,我们很少见过象他这么有天赋的小孩.

第一个选A
第二个A是现在完成时,表示从过去的某一时刻到现在还没有看到一个像他那样有天赋的孩子;B是一般过去时,只表示过去那一时刻没看见过像他那样有天赋的孩子,没有表示现在的意思。

第一题选A.主语一致,意为我之前从未看过。第二题我们之前从未见过像朗朗这样有天赋的应用过去完成式,B是一般过去式,两者时态不同。

第一题A
第二题A是现在完成时,主要用于表达时间到目前为止已经完成了的动作,事件等。有给人“完成”的暗示。B是一般过去时,没有前者的那种暗示意味,只是对过去发生的事件,动作的陈述。
