请以Tom的身份给Jenny写一封回信，描述你自己的房间，文字不少于50词。

Hello,

    This is a picture of my room. There's a bed, of course, and there are two pictures of movie stars above

the bed.

    There's a bookcase next to the bed. There are lots of books on it. There is a radio under the bookcase,

and there are also some CDs.

     There is a dresser in the other corner. There is a table and a chair under the window, between the dresser

and the bookcase. I do my homework and write letters, too. There is a computer on the table. There is a

lamp on the table, too.

     The room is not perfect. There isn't a TV and there isn't a telephone! Tell me about your room. Is it big?

                                                                                                                                                  Love, 

                                                                                                                                                  Jenny
