[解析]
This is the first time that I had been away from home, so I find it hard to live here. How I wish I can turn to Lucy, who once gave me much help! I had trouble with my study in Grade 9. So frustrating was I that I began to play computer games after school, when I should have paid more attention to catching up with others. Beside, I was even caught cheating in the exam, it worried my parents a lot. When asking about the reason why I fell far behind, I was too guilty to say a word. It was then∧ Lucy came to my help, telling me not to give up. To my amazement, I made a great progress. Finally, I even became one of the top student in my class. I must say thanks to Lucy, without whose help, I could never have had so good grades.
解析:
1.had﹣﹣﹣have.考查固定句式.表示"某人第一次做某事"用固定结构This is the first time that+现在完成时态;This was the first time that+过去完成时态.本句的主句是前者,所以从句的谓语动词用have been.
2. can═could.考查情态动词.wish后跟虚拟语气,所以用情态动词could.
3.frustrating﹣﹣﹣frustrated.考查形容词辨析.做表语,修饰主语I,用frustrated表示"沮丧的".
4.Beside﹣﹣﹣Besides.考查形式相似的单词辨析.Beside表示"在…旁边";Besides表示"除了,此外".本句表示"此外,我被捉住考试作弊",所以用Besides.
5.it﹣﹣﹣which..考查定语从句.I was even caught cheating in the exam和it worried my parents a lot之间是逗号,所以应该构成主从复合句,因此应该用关系代词which代指主句,表示"这一件事",it只是一个普通代词不能引导非限制性定语从句.
6.asking﹣﹣﹣asked.考查非谓语动词.做时间状语,和主语I之间是被动关系,用过去分词asked,表示"当被问到原因的时候".
7.then后加that.考查强调句式.本句可以写成then Lucy came to my help,因此可以看出这是强调时间状语then 的强调句式,所以then后加that,和It was 构成强调句式.
8.去掉a.考查冠词.progress表示"进步"是不可数名词,所以去掉a.
9.student﹣﹣﹣students.考查名词.根据修饰词one of the top,可知表示"最好的学生之一",所以用可数名词复数students.
10. so改成such.考查固定句型.grades是名词,所以用such+形容词+名词结构.故改成such.
