I must ask him t give up smking.
ask sb. t d sth. 叫某人做某事
Eg: 我妈妈叫我晚上不要外出。 My mther asks me nt t g ut at night.
give up sth./ding sth. 放弃某事/做某事
Eg: 我不会放弃我的计划。 I wn’t give up my plan.
(一)、must的个性: must拥有情态动词家族的共性:无人称和数的变化,也无时态变化。作谓语时一律用“must +动词原形”结构。
你知道must的用法么?
(二)、must的本领: (1)must表示说话人的主观看法或愿望,认为“必须”做某事。 例如: I ______ ______ hard. 我必须努力学习。 (2)表示要求某人必须做某事时,主语用其它人称。 例如: Yu must wait in line. 你必须排队等候。
must study
(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“一定是,一定在”。当情态动词may与be连用,表示推测“或许是,或许在”。在否定句型表示推测的含义时不用mustn't(禁止,不允许)而用 can't(不可能)。例如: She ______ ______ur new Chinese teacher. 她一定是我们的新的语文老师。 The dr is clsed. He ______ ____ at hme. 门关着,他一定不在家。
can't be
(三)、must的变脸: (1)must的否定式是在must后面加上nt,常缩写成mustn't,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N, yu mustn't / can't。 例如:Yu _________ tell her this news. 你绝不能 (千万不要)告诉她这消息。 Yu ________ ______smke here.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”解时,要注意肯定与否定回答时的用语。其肯定简略答语是Yes,主语+ must。若是否定回答,则是N,主语+needn't或dn't have t。 例如:—Must I finish my hmewrk tday? 今天我必须完成我的作业吗? —N,yu _________ / Yes, yu______. 不必。/ 对,你必须完成。
