Oh, I think

Dear Joe,

    You and your family are in Beijing, China, right? I'm fine. are you these days? And how are your school days? Today is Monday. is your first class? Is it English? is your English teacher? Is she Ms. Lian? Do you like her? And  do you like her? Is it because her classes are interesting? Do you like your Chinese teacher?  do you have Chinese? Is it on Monday, too?

Yours,

Sonia

    Mr. Smith is English. He teaches English well. His English classes are very interesting. ①He likes us and we like him, too.

    Mr. Smith has two children-Tom and Lucy. Tom is seven and his sister is four. Tom goes to school but Lucy doesn't. Mr. Smith likes to wear a T-shirt. It makes him feel comfortable（舒适的）.②Football is his favorite sport. But we like basketball best. After school we often have a basketball match. Sometimes Mr. Smith joins us. He plays basketball just for fun.

—Because they are very cute.
