情态动词have t与must
情态动词must和have t都有“必须”的含义，它们的用法如下：
must “必须”、“应该”的用法:1. must 表示“必须”、“应该”。例：We must listen t the teacher carefully in class. 我们必须专心听讲。 Everyne must bey the schl rules. 每个人必须遵守校规。
2. must的否定形式must nt=mustn’t表示“不应该”、“禁止”、“不准”。语气比较强烈。 例：Yu mustn’t talk in class. 你上课不准讲话。 We mustn’t be late fr schl. 我们上学禁止迟到。
3.must开头的一般疑问句，肯定回答用must，但否定回答用needn’t 或dn’t have t。而不用mustn’t来回答—Must I d my hmewrk befre 8 this evening?—Yes, yu must. —N, yu needn’t./N, yu dn’t have t.
have t 表示“必须”、“不得不”，三单现形式为has t, 过去式为had t例：He has t stay in bed fr 3 r 4 days. We will have t get up early tmrrw.
must与 have t的区别：must表示的是说话人的主观看法，而have t则表示的是客观需要。I must g nw. (主观看法)My mther is ill, s I have t g nw. (客观需要)
