One day I went shopping at a gift shop in Shanghai. I was greatly interesting and I lost me in beautiful goods. After I paid for that I had bought, I left my handbag on the counter. There was about two thousands yuan in it. I had already walked out of the shop while a young shop assistant walked up to me in my handbag. He insisted on my check it. I opened the handbag and found nothing losing. I thanked him and offered him a reward of 100 yuan, he refused to take anything. I was deeply moved by his selfless act on that day.

解析：如上
1.interesting（改为interested）; （主语是人的时候用interested）
2.me (改为myself)(固定词组lose oneself in使自己迷失在…中)
3.that (改为what)（在名词性从句中that不做成分，也没有含义；而what经常在句中充当成分，该句中的that做的就是bought的宾语）
4.thousands (改为thousand)（thousand在与数词搭配时要用单数形式 ）
5.while (改为when)（while只和延续性的动词连用，而walk是短暂性动词；when既可以和非延续性动词连用，又可以和延续性动词连用。）
6.in (with表示伴随，例如：Our teacher came in with a book in hand.)
7.check (改为checking)（insist on doing /my doing 坚持做...）
8.losing(改为lost)（find +宾语+宾补；形容词lost宾语补足语）
9. (加上but)(这里表示转折关系)
10.on (去掉on)（像短语that day,next year等短语前面，都不加the）
