帮我看看这句英文对不对?急急急

不对
I don't know how I could remember it
宾语从句中从句语序要改为陈述句语序

不对！
I don't know how I can remember it !
首先， how后面的从句应写成陈述句语序！
然后，前后时态要一致，所以应该用can!
最后，I 应该大写！我想你也知道

这句话应该这样说:I donnot know how I could remember it.

I have no idea about how could i remember it

could 是表示委婉语气吗,若是就是
I don't know how I could remember it.
若不需要就改为can较好
另外还可以用简单句
I don't know how to remember it.
