One Thing I'm Proud of

　I still remember how I became agood table tennis player.

　The first day I went to high school,I saw some of my classmates playing table tennis. Amazed at how skilful they were,I was determined to be just as good. Later on, I often watched them carefully tolearn their techniques. Then I kept practising until I became confident enough to challenge the good players. At the end of the term I became one of the best playersin my class.

　I am really proud of this experience,because it helps me realize that we all can fulfil our potential and achieve our goals through hard work. It also helps me better understand the proverb “Practice makes perfect.”

试题解析从文章体裁分析，本文是一篇典型的开放式记叙文的写作，主要让学生就one thing  I’m proud of展开叙述，同时写出自豪的原因和启示。应从三方面来写：一 ：叙述自豪的事情。二：重点叙述事情的经过。三：说明自豪的理由在写作过程中注意好词好句的应用

【亮点说明】

文章使用了非常好的短语和句子给文章增色，如：I saw some of my classmates playing table tennis。（see sb doing看见某人正在做某事）, Amazed at how skilful they were,I was determined to be just as good.形容词短语Amazed at做原因状语，（be determined to do） 下定决心做某事. 　I am really proud of this experience (be proud of 以。。。。。为自豪)，并且主语了句子的衔接如：then，also 等。
