Joseph has written a letter to his coustins，james and Susan．Here is the letter．
Dear James and Susan，
    I am writing to you again because I am at home in bed．I have a cold recently and I am unable to go to school．I really have more than a cold，it's the flu．I've got a fever and a severe headache as well．I lose my appetite and I find food tasteless．In addition，writing a letter to you and another to pauline．
    The weather here in Toronto is horrible．I am sure the weather is much better in Hong Kong．Do you agree？The snow came a bit early this year and it was freezing cold．There's a foot of snow on the ground．It's surprising to see kids cheerfully playing in the snow and building"castles"and snowmen this morning．A few of them made snowballs by pressing snow together and threw them at each other．
    I am going to have my examination soon．I'm extremely worried about it because I'm too sick to get out of bed and hold my text-books．What's more，I haven't attended lessons for nearly one week．I have to work hard to catch up with my classmates．
    I have got a new mate recently．He's on my bed．That is Bobby，our cat．Uncle Tom gave him to me as my birthday present．He is rather disobedient and he runs here and there from time to time．He's much more energetic than me．However，I'm glad to have him with me at the moment．
     Well，I am quite tired from writing this letter（and there's a football game on TV）．I'll finish here．Please write to me if you have time．
    Give my regards to your Mom and Dad．
Best wishes，
Joseph
