My English is so poor.
Today I made many mistakes about grammar.Oh my god.what a terrible English I have.I added a friend who told me that I shouldn't use "demand" because it have a strong tone,meanwhile,this request makes negative.However,I didn't realize it before .I am so sorry about it impolite behavior.Besides ,I commented a close friend's biog,I also made mistakes.I am not sure how to use "what\how".She is very nice to tell me the error where I had made.What's more, told me that I have many spaces to improve .Thanks for her encouragement.
There is no denying that English is necessary for us to study,especially my major is psychology.
Mybe this blog also have many mistakes ....
