初中英语祈使句 祈使句指的是表示命令、请求、建议或劝告的句子。其主语 you 常省略，谓语动词用原形，句末用感叹号或句号,读降调。1。肯定的祈使句(1）动词原形+其他 Stand up,please。=Please stand up。请起立.(2）Be+n。/adj。Be a good boy！要做一个好孩子！Be careful!=Look out！=Take care!小心/当心！(3）Let+宾语+动词原形+其它成分 Let me help you。让我来帮你。Lets go to school together.咱们一起上学去吧。2。否定的祈使句（1）Dont+动词原形 Dont stand up。别站起来。Dont be careless.别粗心。Dont let them play with fire。别让他们玩火。（2）Let 型的否定式有两种:“Dont+let+宾语+动词原形+其它成分和“Let+宾语 +not+动词原形+其它成分”.Dont 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 wont。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 wont 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：-Dont go out，please.Its 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。5。祈使句的反意疑问句 (1)肯定祈使句的反意疑问句反问部分用 will you 或 wont you.Please open the door,will/wont you?请把门打开，好吗？（2）否定祈使句的反意疑问句反问部分只用 will you.Dont be late again，will you?别再迟到了，行不行？(3)以 lets 开头的祈使句反意疑问句反问部分用 shall we。Lets turn on the TV，shall we?我们把电视打开,好吗？特别注意 只有以 lets 开头的祈使句的反意疑问句的反问部分才用 shall we,而 let us 开 头的祈使句的反意疑问句的反问部分应为 will you 或 wont you。如:Let us stay here，will/wont you？请(你）让我们留在这好吗?一。用括号内所给动词的适当形式填空。1.Its an important meeting._(not，be)late。2._(not，make）any nise!Your mother is sleeping。3._（not，speak)with your mouth full of food and _(be）polite.4._(not,talk）and _(read)aloud.5._(not，leave)your homework for tomorrow，Larry。6._(look）out!A car is coming。7._（give)us ten years and just see what our country will be like。8._(not，let)the baby cry。9.Wear more clothes or you _(catch)a cold.10。Lets _（not，say）anything about it.二、单项选择 1.The TV is too loud。Please_.A。turn it down B.to turn it down C。turn down it D。to turn down it 2。_ late again，Bill！A.Dont to be B。Dont be C。Not be D。Be not 3._ cross the road until the traffic lights turn green.A.Not B.Wont C。Doesnt D.Dont 4.Please help me carry it,_？A。will I B.will you C.shall I D.shall we 5。Dont make so much noise,_？A.will you B.wont you C。shall we D。do you 6.Do you know the girl _under the tree？A。stand B。to stand C。standing D。stood 7。Kate，_ your homework here tomorrow.A.bring B。brings C.to bring D。bringing 8。_ me the truth，or Ill be angry.A.Telling B。To tell C。Told D.Tell 9.Ive kept the dog _Maomao for a long time.A。Name B.named C。naming D。to name 10。Dont you know that _ is good for our health?A.swim B。swimming C。swam D.swims 11.Her doctor said:“_ work so hard”A Stop B Dont C Cant D No 12。Sindy，_ to be here at 8 oclock A is sure B is sure that C will be sure D be sure 13。_ when you cross the road。A Do care B Care C Do be careful D To be careful 14。_him the secret，will you？A Dont tell B Not to tell C Not telling D No telling 15._ in bed.Its bad for your eyes。A Not to read B Dont read C Dont to read D Not read 16._ Your child。Well look after him.A Not to worry about B Dont worry about C Not worry for D Dont worry with 17.They are very tired.Why _ have a rest？A not they B do not they C dont they D not to 18-You look rather tired。_ stopping to have a rest?-All right。A Why not B How about C Why not to D why dont 19 _ tell a lie。A Hardly B Not C No D Never 20.Please _ look outside。Look at the blackboard。A not B dont C arent D cant 三、句型转换 1。Will you please read it again more slowly？（改为祈使句)_ _ again more slowly，please.2.If you dont listen to me,Ill go。（改为同义句）_ _me，or Ill go.3。Lets watch the sports games.(改为反意疑问句）Lets watch the sports games,_ _？4。The teachers often tell the students not to be careless。（改为祈使句）_ _careless，please.5。Please sit next to Nancy。（改为否定句）_ _ next to Nancy.6。Dont forget to turn off the lights,please.(改为反意疑问句）Dont forget to turn off the lights，_ _?7。If you move，youll die.（改为同义句）_ _，or youll die。8。Come to my house tomorrow.（改为反意疑问句）Come to my house tomorrow,_ _?9.这是一个坏了的被子。（翻译句子）This is a _ _。10.让我们去帮帮那个哭泣的女孩吧。（翻译句子)Lets go and help the _ _,please.四、将下列汉语翻译成英语.1.请照看好您的包。_.2.让我们去学校吧!_！3.亲爱的，高兴点儿！_!4.不要把书放这儿。_。5.不要让猫进来。_.参考答案 一、填空题 1。Dontt be 2.Dontt make 3.Dontt speak be 4.Dont talk read 5。Dont leave 6。Look 7。Give 8。Dont let 9.catch 10.not _say 二、单选题 15。ABDBA 610.CADBB 1115 BADAD 16-20 BDADB 三、句型转换 1.Read it 2。Listen to 3。shall we 4.Dont be 5.Dont sit 6.will you 7。Dont move 8。will/wont you 9.broken glass/cup 10.crying girl 四、翻译 Key：1。Please look after your bag。2.Lets go to school。3.Be glad，dear 4.Dont put the book here。5.Dont let the cat come in/Let the cat not come in
