Using must and have t
must与have t是两个常用的情态动词，两词后面都接动词原形。在使用时，应注意两词间的差别。must 表示主语“有义务”的“必须”做某事，强调说话人的主观看法，主要用于肯定句和疑问句；must 还可以表示肯定推测，意思是“一定”。have t 强调的是客观需要，意思是“不得不”。have t 有人称和数的变化。
I must wrk hard at my lessns.      我必须努力学习功课。(主观意愿）I have t lk after mther at hme.  Fr she is ill. 我得在家照看妈妈，因为她病了。(客观需要）It is getting dark. He has t g hme nw.天快黑了。他现在得回家了。(客观需要）
must的否定形式是must nt，其缩写为mustn’t，表示禁止，意思是“不能，不许”。have t的否定形式是d nt have t，其缩写为dn’t have t。 Yu mustn’t make any nise in class.上课时你们不许吵闹。Yu dn’t have t water the flwers. Fr it is ging t rain.你们不必浇花了，因为要下雨了。
