My parents took me to Japan when I was little．I lived there for five years． 31 I come back．my Japanese was very good．"Can I do something useful with my Japanese?．"I asked myself.
Then,one day last spring,I got a good opportunity．
Everyone was afraid of SARS,So I stayed at home with 32 to do．
My father brought me a Japanese book．"Why don't you translate it into Chinese?It will be better than 33 computer games all day．"
I promised（承诺）to do 2000 words each day．But 34 I found it was hard to keep the promise．
One day in May,the weather was beautiful．But I couldn't go out．Those 2000 words were still 35 me．
After translating only three pages,I already lost interest：in the book．
