(2)否定形式:主语+don't have to+动词原形+其他 (一般现在时.主语是第三人称单数时.用doesn't have to. 句子是过去时.用didn't have to) 如:Nick doesn't have to wear a uniform. 尼克不必穿制服.We didn't have to do our homework at once. 我们不必马上完成作业. (3)疑问句:Do +主语+have to +动词原形+其他 如:Do you have to stay at home on weekends? 周末你必须呆在家里吗?Yes, I do. / No, I don't. 是的.我必须.不.我不必.Did he have to go to bed by 11:00 last night? 昨晚.他不得不11点前上床睡觉吗? 2. 情态动词can的用法 (1)表示能力."会""能"(在第一册中已经学习这种用法) Can you play the guitar? 你会弹吉它吗?Judy can speak a little Chinese. 朱蒂会说一点中文.I can dance and sing. 我能唱歌又能跳舞. (2)表示允许.许可."可以"."能" Can the students run in the hallways? 学生们可以在走廊上跑吗?We can eat outside. 我们可以在外面吃东西.Can I come in? 我能进来吗? 注意 同样是情态动词.can 和have to 的用法是有区别的.和大部分情态动词一样.can在否定句中.直接在can后加上not.在疑问句中.把can放到主语前面.并且没有人称和数的变化. 3. hear.listen和sound都有"听"的意思.但三者是有区别的. (1)hear"听说".侧重于"听"的内容 I'm sorry to hear that you are ill. 听说你生病了.我很难过. I never heard such an interesting story. 我从来没听过这么有趣的一个故事. (2)listen"听"侧重于"听"这一动作.Listen to me carefully. 认真听我说. The children like to listen to music. 孩子们喜欢听音乐. (3)sound"听起来".它是系动词.后面接形容词等.That sounds great. 那听起来真不错. It sounds like fun. 听起来挺有趣. 4. be in bed "在床上.卧床"in 和bed之间不能用冠词.bed也不用复数. He is in bed for 10 years. 他卧床10年了.Dave has to be in bed early every night.大卫每晚必须很早睡觉. 5. arrive late for 与be late for 意思相近."迟到"Don't arrive (be)late for school. 上学别迟到.I arrived (was)late for the meeting yesterday. 我昨天开会迟到了. 6. No talking ! "禁止交谈!"no后面加上名词或动名词也表示不要做某事.与don't +do的用法相似.No wet umbrellas! / Don't put wet umbrellas here! 禁止放湿雨伞! No food! Don't eat food here! 禁止吃食物!No smoking! Don't smoke here! 禁止吸烟! 7.语法 祈使句是用来表示请求.命令.叮嘱.号召或者劝告等的句子.这类句子的主语常是第二人称you.也就是听话者.因而you常省去了.祈使句的开头是动词原形. 如:Look out! 小心!Wait here for me! 在这等我! Be sure to come here on time! 务必准时来到这里! 祈使句的否定形式多以do not开头.再加上动词原形. Don't arrive late for school. 上学别迟到. Don't fight! 别打架! Don't look out of the window. 不要向窗外看. 查看更多
