Last week, when we learned the new word "slovenly", we asked to make a sentence with it. I volunteered to do it by saying "My deskmate is a slovenly girl who clothes never fit her." Hearing this, a whole class burst into laughter and my deskmate face turned red. After class, I learned up from the teacher that my deskmate would have dropped out of school if she hadn' t been helped with others. My mindless words must have hurt him deeply. Not until then do I realize words could be powerfully in both positive and negative ways. We should avoid hurt others if our words are not encouraging.
第一处：asked 前加 were 。考查语态。该句的主语 we 是动词 ask 所表动作的承受者，故用被动语态，即 “be 动词 + 过去分词 ” 。
第二处：who→whose 。考查定语从句。引导词在从句中作 clothes 的定语，故用 whose 引导。
第三处：a→the。考查冠词。 the whole class 表示 “ 全班学生 ” 。
第四处：deskmate→deskmate's 。考查名词所有格。此处应该用名词的所有格形式，表示 “ 我同学的脸 ” 。
第五处：删掉 learn 后的 up 。考查固定短语。 learn from sb ．意为 “ 向某人学习，从 …… 获知 ” 。
第六处：with→by。考查介词。被动语态的动作执行者一般由介词 by 引出。
第七处：him→her。考查代词。上文提到作者的同桌是女生，这里应该用宾格形式 her 。
第八处：do→did。考查时态。上下文用的都是一般过去时，根据时态一致的原则，此处也用一般过去时。
第九处：powerfully→powerful。考查形容词。 be 动词后应该用形容词作表语。
第十处：hurt→hurting。考查固定用法。 avoid 后面只能跟动词的 -ing 形式作宾语，意为 “ 避免做某事 ” 。
