Can I help you?
Could you open the window? 在表示有能力作某事时,could是can的过去式。I can swim.I could swim at the age of five.Must /have to
Must 表示主观意愿,否定句用Mustn’t,否定回答用needn’t
I must go now.You mustn’t play in the street.Must I clean the room now?
No,you needn’t.have to表示客观条件的限制的“不得不”,它有时态和人称变化,需要助动词来否定和疑问。I don’t have to carry the big box.He had to wash his clothes.May
表示请求别人允许。May I use your bike? 表示可能性。
