“你最难忘的经历”可不可以说What's the most unforgettable experience you had been?

what is the most unforgetable thing you have been experienced
如果是你中文的话就把WHAT IS 去掉就可以了
还有 你的FORGETABLE拼错了

the most unforgettable moment you have ever experienced.

What's the most unforgettable experience you have?

最简单的改法。去掉WHAT'S

不行，念不通，意思不对
