–I _____ a rainbow in the sky after the rain.-Really?Do you know how many colours _____
in a rainbow?
A.just have seen; there are B.have just seen; are there C.just saw; there are D.have just seen; there are

看来上面两楼出现矛盾了
通过表示时态的状语：after the rain说明表示“曾经见过”,所以用完成时.
how引导宾语从句,做know的宾语,并不是引导疑问句,所以陈述语气
再问：但是有明确过去时间状语的句子不是应该用过去时态吗？
再答：如果有yesterday这种表示过去的时间的当然是过去式，但after the rain表示一种曾经观察过的情景。这题用排除法稍微舒服些，因为没有表过去的时态，所以直接排除C就行
再问：还是不明白哎。after the rain 难道不是过去的时间吗？c 就是过去时态啊。
再答：你这样想，我曾在雨后看见过彩虹，你用完成时还是过去式？肯定是翻译成I have see a rainbow after the rain。这道题是一个道理。你就这么记，凡是表示有过什么经历的句子，都是完成时。比如我去过美国，I have been to us before。或者我吃过香蕉I have eaten the banana。
