【妙辨异同】
else ：意为“其他的”，用于疑问词或不定代词之后。

语法重点：情态动词表推测
定义
表示可能、怀疑、允诺、愿望、义务、必要、猜测等的动词就是情态动词。英语中表示推测的情态动词主要有 must，can，could，may，might等。
语法特征
1.情态动词不能表示正在发生或已经发生的事情，只表示期待或估计某事的发生。
2.情态动词除ought 和have 外，后面只能接不带to 的不定式。
3.情态动词没有人称、数的变化，即情态动词第三人称单数不加-s。
4.情态动词没有非谓语形式，即没有不定式、分词等形式。
can 可表示能力、允许、可能性、怀疑猜测，意为“可以，会，能”；can’t意为“不会，不能，不可以”，还有“不可能”之意。could为can的过去式，用法与can类似，常用于过去时态中；could还可用于现在时态中表示委婉客气，相当于can；could也可表示惊讶怀疑，不相信。can’t和couldn’t 一般用于否定句和疑问句中。
1.can
eg：He couldn’t be a thief.
2.may
may表示允许、也许，意为“也许；可能；可以”，语气不太可能。对may的一般问句的回答：
肯定回答一般是：Yes, please./ Certainly./ Sure等
否定回答一般是：Please don’t./No, you can’t/mustn’t.
might是may的过去式，与may用法类似，语气比may弱，表示推测的可能性更小，常用于肯定句和否定句中，不用于疑问句中。
3.must
must 表示必须要做的事，意为“必须，应该”。must一般问句的否定回答用needn’t或don’t have to , 而不用mustn’t， mustn’t意为“不可以，不能”，表示禁止，不许可。另外，must还可表示有把握的推测意为“一定、肯定”。must的过去式还是must。
在回答以must开头的一般疑问句时，否定式需用need not (needn’t)，表示“不必”的意思。
eg：— Must we hand in our exercises today
— Yes, you must. ( No, you needn’t)
