1. 情态动词本身有一定的词义，通常与动词原形一起构成谓语，表示说话人的看法或主观设想。常见的情态动词有：can、culd、may、might、must、ught t、shall、shuld、will 和 wuld。另外，dare、need、have t 和 used t 也具有情态动词的某些特性。
2 can 与 culd 表示能力（ability），意思相当于 be able t。如：Jack can swim. My father culd stand n his hands when he was yung. 注意：在一般过去时中，was / were able t 通常表示能做并且已经做了的事，culd 仅表示能力。 如：I was able t swim t the bank when the ship sank. I culd lift the heavy bx.
3 must 与 need 表示必要性（necessity）。must 意为“必须”，否定式 mustn’t 意为“不许”；need 意为“需要”，否定式 needn’t 意为“不必”。如： I must g nw. Yu mustn’t frget yur ticket. Need we g right nw? Yu needn’t d it if yu dn’t want t.
注意：have t 也有“必须”的含义，但侧重客观需求，有时态的变化，否定式是 dn’t / desn’t have t，意为“不必”，意思相当于 needn’t。如：We will have t think f a new plan.Yu dn’t have t run.
4 can、culd、may 与 might 表示许可（permissin）。表示许可时，may 多用于正式场合，culd 和 might 的语气更委婉些。如： Yu can use my pen if yu like. Students may nt bring their pets t schl. Culd / Might I brrw yur bike?
5 can、culd、may 、might 与must 表示可能性（pssibility）。may、might和culd常用于肯定句，意为“可能”，must用于肯定句，意为“一定”；否定式may/might nt意为“可能不”，can’t/culdn’t意为“不可能，肯定不”。如： That may/might/culd be a gd idea. Yu must be tired after the lng jurney. There may nt be enugh mney t pay fr a new car. Yur stry can’t/culdn’t be true.
注意：can表示可能性时，含有“有时会”的意思。如：The temperature here can be as high as 37℃.
6 shuld 与 ught t 表示义务（bligatin）或建议（suggestin），意为“应该”。如： They shuld / ught t build mre libraries. 注意：shuld 与 ught t 也可以表示主观判断，意思是“可能会，应该会”，相当于 will prbably。如： The rain shuld / ught t stp sn.
7 will 与 wuld 1) 表示习惯性动作（habit），will 表示现在的习惯，wuld 表示过去的习惯。如： Mary will listen t music fr hurs in her rm. I wuld take a walk after supper when I was yung. 2) 表示意愿（willingness）。如： The baby wn’t g t sleep. 3) 表示请求（request），wuld 比 will 更委婉些。如： Wuld yu give me sme advice?
注意：used t也表示过去的习惯性动作，多用于非正式场合，往往指后来停止了的动作。否定形式是 didn’t use t 或 used nt t。如： I used t have a bicycle, but I sld it.Jhn didn’t use t cme here.Did Mike use t read newspapers?
8 shall1) 在疑问句中，表示建议或征求意见。如： Shall I help yu with the bx?2) 表示承诺或要求。如： Yu shall have the magazine. He shall d as I tell him.3) 用于正式文件、法律、规章制度等，表示规定。如： Students shall nt use calculatrs during exams.

10 情态动词的进行式、完成式和被动式 1) 情态动词可以与主动词的进行式合用，表示某动作正在进行。如： Jack may be reading in the library. 2) 情态动词可以与主动词的完成式合用，表示过去发生的动作。如： Tm must have arrived hme by nw. Yu can’t have seen Henry yesterday because he was in Lndn. 3) 情态动词可以与主动词的被动式合用。如： The rad may be blcked.
