本次课讲解内容-------情态动词与形容词比较级/最高级
Part 1: 情态动词:Can, May, Must, Should, Will, Would, Need
注意:情态动词无人称和数的变化,不能单独使用,后面必须+动词原形
Can 可以/可能表示能够(能力) May 可能;可以表示允许;请求;语气委婉 Must表示必须mustn’t表示禁止
need 表必要性;否定:needn’t should表示应该;建议 will表示将要
would是will的过去式;would you like to....?你愿意.....吗?
have to 必须(不是规章制度的必须)
否定形式:
can-----can’t 不可能/不可以 may------may not不可能 must-----mustn’t禁止
need----needn’t不必 should----shouldn’t不应该 will ----won’t不会
would-----wouldn’t have to-----don’t have to不必
特别注意1):当must提问时,否定不能用Must n’t 回答。
如: Must I finish my homework today
否定回答:No, you needn’t.
肯定回答:Yes, you must.
特别注意2):need 需要;don’t need 不需要。但是当need作为情态动词使用,为必要,其否定为needn’t.
Part 2 :形容词比较级与最高级:
比较级:更......+er 最高级:最.......+est
比较级:两者的比较------常见短语more than : 更.......
最高级:三者的比较-------one of the+形容词最高级: 最......

如:as much as 与....一样多; as smart as与....一样聪明
the more......the more......越来....越.......
