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.
