    I arrived in New York two weeks ago.I am writing my diary(日记)in English because my English teacher Rachel says it is a good way to practise English.So far, I like New York and my school.I have three classes a day.Most of my classmates come from Japan,South Korea,Spain,Germany and Australia.There aren't many Chinese students.so I have to use English most of the time.I am learning a lot!I am living in student housing,and I have my own comfortable room.

    My English is hopeless!I was on the bus this morning and a man spoke to me,but I couldn't understand him.I was so embarrassed(尴尬的).Why is my English improving so slowly?I want to make lots of American friends,but this isn't happening so easily.I'm a shy girl.It is hard for me to talk to some people,even my classmates!I like them,but sometimes I can't understand them very well.I think I'm feeling homesick(想家的).I miss my friends and family.
