短文改错（共10小题；每小题1分，满分10分）
Dear David,
I have recently felt guilty, stay sleepless at night. You may wonder how. To tell you the truth, it is just because of the factthatI seldom cheat in exams and I just can’t stop me. In many exams, I used cellphones to surf the net for answer. Besides, I sometimes referred themto my notebooks so copied something. As you know, cheating do much harm to our learning and self-confidence. It’s time that I take action to stop it. I would appreciate it you could offer me some advice.
Looking forward to your reply!stay改成 staying

(答案→)stay改成 staying 解析：【小题1】stay改成 staying，这里是现在分词做伴随状语【小题2】how改成why ，从后面的because of，可知是问原因【小题3】seldom 改成often，句意：我经常考试作弊【小题4】me改成myself，主语是I，宾语应该是myself【小题5】answer是可数名词， 改成answers【小题6】refer to my notebooks参考笔记【小题7】so 改成and，有时看笔记抄东西，是并列关系【小题8】do改成 does 主语是cheating，谓语是单数【小题9】take改成took或前加should，It’s time +从句的句型，从句中用虚拟语气，sb should do或sb did。【小题10】it后面加if ，句型I would appreciate it if…，如果…我会很感激…
