Hi Li Xiufang. Great effort here. This is generally grammatically accurate and you get your point across well.  Note that in the 'Sometimes...' sentence, you cannot simply join two clauses together with a comma (,). I added the word 'when' here to allow for the next clause to follow on. Hope this helps! Hugh 

I prefer to go shopping for pleasure

Some people do not enjoy shopping and shop only when they have a specific purchase to make. Others like to go shopping for pleasure whether or not they have something to buy. Which do you prefer and why?

Personally, I prefer to go shopping for pleasure even if I don’t have anything to buy. First, when I am shopping, I can always find some interesting and practical products<font style="background-color: yellow;"> <strike>,</strike></font> <font style="background-color: yellow;">.</font> I am really impressed by their good looking and subtle designs, which always give me some creative ideas for my design<strike><font style="background-color: yellow;">ing</font></strike> work. Second, shopping is not just a necessity; it is also a form of entertainment. Sometimes <font style="background-color: yellow;">when</font> I really feel bored after a long day’s work, shopping can easily get me feel relaxed and refreshed. Besides, it offers me a chance to get extra exercise, which is good for my health.
