As the saying goes, chance the prepared mind. I learned this from one of my .

　　I was not chosen as member of the volleyball team of our school. Because of this, I decided to give up volleyball. Luckily, my best friend stopped me pointed out that it was my laziness and poor preparation led to my failure. After that, I practiced playing volleyball every day. When another chance of trying out arrived, I was prepared and tried my best. As a result, I was selected and became an important player on our school team.

　　 From this, I am firmly that we are able to seize a chance as long as get well prepared.

　　难项分析：

　　第五处：but→and　考查连词。本句中，"stopped"和"pointed out"共同作句子的谓语，为并列关系，故改but为and。

　　第六处：which→that　考查强调句型。本句中宾语从句为强调句，被强调的部分是my laziness and poor preparation；强调句型的结构为It is/was ... that/who ...，故改which为that。

　　第九处：convincing→convinced　考查形容词。convinced表示人"信服的"；convincing表示事物"令人信服的"。此处构成"Sb. be firmly convinced that从句"句型，意为"某人坚信......"，故改convincing为convinced。
