4、n t be careless. 不要粗心。3. Let 引起的祈使句的否定形式有两种：(1)Let 开头的祈使句，如果后面跟第一、第三人称名词或代词的宾格，可在Let 前加 Don t，也可在 Let 后宾格的名词或代词后面加not。(2)如果以 Let s开头的祈使句，必须在Let s后加 not。例如 :Dont let me go with her tomorrow.Let me not go with her tomorrow.不要让我明天跟她一起去。Let s not tell her the truth whenever we meet her.无论什么时候我们碰到她，都不要告诉

13、或条件状语从句相混淆。在平时的练习或测试中，如果稍不留神，就会出错。因此，要认真审题，认真分析句子结构，并根据上下文语境，作出正确判断。例如： _ your composition carefully, some spelling mistakes can be avoided. A. Having checked B. Check C. If you check D. To check 析：如果空白处选填B(Check) 项，则视为祈使句，但后一分句前没有并列连接词and 连接；如选A 或 D项(分词或不定式)，句中逻辑主语some spelling mistakes又不能执行这个动作，故均

14、不符合句子结构。因此，只有 C 项 (条件状语从句 )符合句子结构及句意。2. 考查祈使句型与非谓语动词作状语的辨别能力注意标点符号(如破折号 )的功能， 牢记常见祈使句的结构，排除非谓语动词的干扰(非谓语动词提前作状语，常用逗号与后面分开，表示时间、原因、条件、目的等)。原题再现 答案 : A Ive never seen anyone run so fast - _David go. A. just watch B. just to watch C. just watching D. just having watched 一、 将以下祈使句改为否定式：1. Come here early
