7、2）表示要求某人必须做某事时，主语用其它人称。例如： You must wait in line. 你必须排队等候。 （3）在肯定句中，must可以表推测，语气要比may肯定得多。must表示对某事把握很大的推测，只能用于肯定句，意为“想必；准是；很可能”； must be表示“必定无误”。当表示对现在的情况进行推测时，must后也接动词原形或动词的现在分词。当情态动词may与be连用，表示推测时，其肯定程度比must要小得多。在否定句型表示推测的含义时不用mustnt而用 cant。例如： She _ _our new Chinese teacher.她一定是我们的新的语文老师。The do

8、or is closed. He cant be at home. 门关着，他一定不在家。 (三)、must的变脸： （1）must的否定式是在must后面加上not，常缩写成mustnt，意思是“决不可；千万不能；务必不要；禁止”。在对May I .?作否定回答时用No， you mustnt / cant。例如： You _ tell her this news. 你绝不能（千万不要）告诉她这消息。 You _ _smoke her.e你绝不能在这儿抽烟。（2）must的疑问式是将must提在主语前。must用在问句中作“必须”解，这时要注意肯定与否定回答时的用语。其肯定简略答语是Yes，

9、主语+ must。若是否定回答，则是No，主语+neednt或dont have to。例如： Must I finish my homework today? 今天我必须完成我的作业吗？ No，you _ / Yes， you_. 不必。/ 对，你必须完成。2. give up【课文原句】_.【导学点拨】give up放弃，当后面接动词作宾语时，应用 v.-ing形式。 give up doing sth. =stop doing sth.e.g. You should stop _. =You should _ _ _. 你应该戒烟。3.throw litter around【课文原句】_

10、.【导学点拨】 throw around意为“抛撒.” aroundt在这里是副词，与throw一起构成动词短语。后接宾语如果是名词时放在副词前后都可，是代词时只可放在动词和副词之间。即 “名词两边，代词中间”。e.g. Dont _ _ _.别乱扔它。Dont throw waste paper around= Dont throw around waste paper.不要到处扔废纸。 4. be necessary for【课文原句】_.【导学点拨】be necessary for对于来说是必不可少的e.g. Sunshine _ _ _our life. 阳光对于我们的生活来说是必不可

11、少的。5. be good for【课文原句】_.【导学点拨】be good for 对好，有益。e.g. Exercise _ _ _ our bodies. 运动对我们的身体有益.6. during the day【课文原句】_.【导学点拨】during the day在一天中，相当于 in the daytime during prep.在期间 e.g. during the holidays在假期里五、目标检测 Practice I.根据句意及首字母提示填空。1.
