急求，各位英语高手帮忙。 谢谢了。

How time flies!

These【Those】10 days were really a fond memory for me.

In fact, the happiest fairy tale is no more than the simple days we have 【spent】together.

I will keep that deeply in my heart 【mind】 for ever.
【 keep it in my heart, 人们看得懂，但好像比较中式】

I am grateful to the opportunity we met each other.
【I am grateful to the opportunity which let us meet each other.】

Yes, emotion is the innate weakness of human without me.
【人类的弱点可以用human weakness表达，without me放进去，我没看懂，呵呵】

You don't know I'm missing you so much since the airplane left USA.----
【You know， I'm missing you so much since the airplane left USA. 你要知道，我老想你了----个人觉得这样表达更好些 】

Hope you can come to China 【soon】. I will be waiting for you.
【套句歌词也不错：I will be right here waiting for you.】

Best wishes for you. 【Best wishes to you.】

写得挺好的，要是收信人是我，能感它若干个动

第二自然段最后一个单词是forever才对
