第一题
为什么用现在完成时
过去时不可以么

Answer 1

1选D
现在完成时，后要跟延续性动词。而BUY是非延续性动词，也就是瞬间动词不合题。HAD是HAVE的过去分词，有延续性质
2选A。被动语态啦。句子结构是是简单句。

Answer 2

1 D buy是瞬间性动词 不能有延续性特征 故不能用long修饰 ；而have表示“有”这个状态，则可以。
2 A now说明要用现在事态 排除C D，被说是被动所以选A

Answer 3

1D打错了吧,应该是:What a nice bike! how long have you had it?因为是有了,所以不能用将来式与现在式.只能用现在完成式.
2A 用被动的,语言是被讲的.

Answer 4

D A

1.-What a nice bike! How long have you had it?

延续性动词 现在完成时态

2.Chinese is spoken by more and more people in the world now.
语言“被”说 用被动语态
