My big issue

Probably native English speaker fells my English like a kid.

I use many "I" When I write English.
I don't know how to connect the sentence in English.

I think some complicated things in my brain by Japanese.
Also I can think its by Chinese, and can express its by both languages.

But I really don't know how to express by English.
Perhaps I must get used to express by English.

My roommate is very cute girl. She is quite clever.
She could speak Chinese well soon. And we talk by Chinese everyday.
I lost a chance for studying English.
(she can speak English very well, also can speak French and hers mother tongue Bosnian)

I love my roommate very much. But She will go her home this summer.
I hope new roommate can not speak Chinese at all and can speak English well.
