16、必须、不得不它侧重于客观上的必要和外界的权威。 结构：主语+have to+动词原形+其他 一般现在时：主语是第三人称单数时用has to，其它时候用have to（过去时：无论人称和单复数都用had to.）Eg:We have to wear sneakers for gym class. 在体育课上我们必须穿运动鞋。 Tom has to practice the guitar every day. 汤姆每天必须练习弹吉它。 （I had to get up at 5:00 am last Monday. 上周一我不得不早上5点起床。） 否定形式:主语+dont have to+动词原形

17、+其他一般现在时:主语是第三人称单数时用doesnt have to,其它时候用dont have to. (过去时: 无论人称和单复数都用didnt have to) Eg:Nick doesnt have to wear a uniform. 尼克不必穿制服。 We didnt have to do our homework at once. 我们不必马上完成作业。 疑问句：Do 、Does或Did+主语+have to +动词原形+其他 Eg:-Do you have to stay at home on weekends? 周末你必须呆在家里吗 -Yes, I do. / No, I

19、意思是“必须，应该”。Eg:You must finish your homework fist.你必须先完成作业。 表示有很大把握的判断或者推测，意思是“一定，准是”。Eg:The tall man must be your father.那个高个子男人一定是你的爸爸。 以must开头的一般疑问句，它的否定回答用neednt（不必要），不用mustnt（不允许），mustnt常用于否定句中表示“不允许，禁止”。Eg:-Must I go there on foot?我必须得走过去吗？ -No,you neednt.不，你不需要。 You mustnt park your car here.你

22、 _.A.neednt B.mustnt C.cant D.may notYour mother _there,she has gone to America.A.must be B.could be C.may be D.cant be4. 祈使句（Imperative Sentence）定义：用于表达命令、请求、劝告、警告、禁止等的句子叫做祈使句，祈使句最常用于表达命令，因此在学校文法中也常称为命令句。祈使句因对象（即主语）是第二人称，所以通常都省略。祈使句的动词都为一般现在时，句末则使用句号或感叹号来表示结束。祈使句的肯定句：行为动词原形+其他Eg:Go and wash your ha

23、nds.去洗你的手。命令 Be quiet, please.= Please be quiet.请安静。请求 Be kind to our sister.对姐妹要和善。劝告 Watch your steps.走路小心。警告 Look out！Danger！小心！危险！强烈警告，已如感叹句 Keep off the grass.勿践草坪。禁止 No parking.禁止停车。禁止以Let开头的祈使句，Let后宾语是是第一人称时，否定形式是在宾语后加not,Eg:Lets not do that again.我们别再那样做了。 如果Let 后面宾语是第三人称，否定形式是在Let前加助动词Dont,

24、Eg:Dont let them come in.别让他们进来。祈使句的否定通常使用“Dont ”，Dont+动词原形（行为动词/be动词）+其他Eg:Dont let the dog in.不要让那只狗进来。 Dont touch, please.请不要用手触摸。 Dont be silly.别傻了。祈使句有时也把主语“You”表达出来，使对方听起来觉得柔和些，例如：Eg:You go and tell him, Chris.克立斯你去告诉他。【典型例题】1_late for class!A.Dont B.Not be C.Dont be2_worry about me Mom.Ive gr
