wuld是will的过去式，可以用于过去将来的时态中。例如：Our teacher said we wuld have a mdel P.E. test this Friday aftenn.wuld用于现在时，表示委婉提出请求、建议或看法，常和please连用，和Culd yu please一样，意为“请你好吗?” 例如：Wuld/Culd yu please nt d it again? 中考对wuld不作要求。
表示许可时，can't意为“不可以”，而mustn't意为“禁止”，“不允许”，语气很强。
表示可能性时，can多用于疑问句和否定句，may则多用于陈述句，can't意为“不可能”， may nt意为“可能不”。如：Can the news be true? N, it can nt be true(不可能).Where can they be nw?Yu'd better ask the pliceman ver there. He may knw the way.What he said may nt be right(可能不).
can't可以意为“不可以”（许可），e.g. Yu can't take the bks ut f the reading rm.“不能”（能力），e.g. My daughter can't swim.“不可能”（可能性）e.g. Mr. Li can't be in the rm. He has gne t Beijing.culdn't仅表示“过去不能”（能力）e.g. I culdn't drive befre 2009.

He is ld enugh t lk after himself.Need I hand in the hmewrk tday？need作行为动词时, 其后跟名词或带t的动词不定式作宾语。可以用于各种句型。e.g. Yu need n mre help, d yu? It's rainy utside.
