读写任务：阅读下面的短文，然后按照要求写一篇150词左右的英语短文。

Dear Wei Hua,

     I'd like to tell you that I managed to achieve a full score of 120 points in Canada, where the IBT TOEFL

was launched earlier this year. I decided to take the test only one month before the due date in June.

     You may wonder how I did it. Now let me tell you. I went over several TOEFL vocabulary books and

practiced a lot of model tests on the computer. Apart from my preparations for the test, my solid language

skills also led to my new TOEFL success. In 2004, I participated in the third "21st Century Cup" National

High School English Speaking Competition held by China Daily as a Junior 3 student and won the top prize.

     Testing speaking skills is an added part of the new TOEFL test. My good performance in this test mostly

resulted from my speech practice before I moved to live and study in Canada last year. To prepare for the

speaking competition, my teacher asked me to make speeches in the canteen at lunch breaks. Surrounded

by many students, I heard them saying, "What's wrong with that girl? Is she crazy?" I had to be brave and

confident enough to stand on the stage when the day came.

     I also believe that Rome wasn't built in one day. To learn English well, we have to keep practicing: listening,

speaking, reading and writing.

Yours,

Chang Mengsu
