don't be careless. 别粗心。 don't let them play with fire. 别让他们玩火。 (2) let型的否定式有两种:“don't + let + 宾语 + 动词原形 + 其它成分”和“let + 宾语 + not + 动词原形 + 其它成分”。 don't let him go. / let him not go. 别让他走。 let them not play with fire. 别让他们玩火。 (3) no开头,用来表示禁止性的祈使句。 no smoking! 禁止吸烟!no fishing! 禁止钓鱼! 3. 祈使句的强调形式,通常在肯定祈使句式前加上助动词do。 例如:do shut up! 快住口! 4. 祈使句的回答 祈使句的动作通常是表示将来发生的动作,所以回答祈使句时,一般用 will或won’t。 在回答具有否定意义的祈使句时,要注意两点: 1) 形式一致(即yes与will保持一致;no与won’t保持一致) 2) 意思相反(即yes是 “不”的意思;no是 “是”的意思)。 在回答时,要注意分析上下文语境中所提供的条件。 如:--- don’t go out, please. it’s raining heavily outside. 请不要出去。外面雨下得很大。 ---- yes, i will. i have to meet my brother at the airport. 不行,我得去机场接我弟弟。 (二)易错点讲解 1、放句首时,要注意don’t后面要用动词原形; 2、当人称后面有标点符号时,要注意是用祈使句还是用三单。 如:lucy, don’t be late again. lucy, a 17-year-old girl, is not late again. 3、祈使句与or的搭配, 如:hands up, or we’ll shoot. 【趁热打铁】 1. _______ late again, bill! a. don't to be b. don't be c. not be d. be not 2. _______ cross the road until the traffic lights turn green. a. not b. won't c. doesn't d. don't 3. kate, _______ your homework here tomorrow. a. bring b. brings c. to bring d. bringing 4. ________ me the truth, or i'll be angry. a. telling b. to tell c. told d. tell 5 .her doctor said: “________ work so hard” a stop b don’t c can’t d no 6. sindy, ________ to be here at 8 o’clock a is sure b is sure that c will be sure d be sure
