注:以上三种句式中情态动词的语气按程度都是依次递减的。Might, could并非may, can的过去式,而表示语气较为委婉或可能性较小。   

(二)情态动词表推测的三种时态   
1. 对将来情况的推测,用“情态动词 + 动词原形”。    
(1)She must / may / might / could arrive before 5.  5: 00 前她一定/可能/也许到。    
(2)She must/may/might/could walk miles and miles among the hills without meeting anyone.   
           她一定/可能/也许会在山里一连走好几英里而遇不到一个人。   
2. 对现在或一般情况的推测,用“情态动词 + be”,“情态动词 +be doing”或 “情态动词 + 动词原形”。

(2)The door was locked. He can ( could ) not / may ( might ) not have been at home . 门锁着,他不可能/可能不在家。   
(3)Can / Could he have gotten the book? 难道他找到书了吗?    
注:情态动词 should /ought to表推测时,意为“想必会,理应……”但与“have +过去 分词”连用时,则又可构成虚拟语气意为“本应该做某事却没做”。 
例如:   
(4)It’s seven o’clock. Jack should/ought to be here at any moment.   
     现在七点钟了,杰克理应随时到达。(推测)   
(5)She should / ought to have attended your birthday party, but she had to look  after her mother in hospital. (虚拟)

    every(everything,everybody,everyone,),all,each,both,much,many,(a)little,(a)few,other(s),
    another,none,one,either, neither等。一般来讲,修饰不定代词的词要置于其后。

    all指三个以上的人、物或群体或泛指一切事物。

    例如:Do you have any other questions?
    the other作形容词或代词,特指两者中或两部分的另一个或另一部分。
    例如:The bookshop is on the other side of the street.
     others相当于“other+名词”,泛指“别的人或物”,只有名词性用法。

    the others相当于“the other+名词”,表示“剩下的,其余的”,特指除此之外的全部 人或物。

    例如:You can take either half.
    Neither of the books is good.

    例如:Many boys like playing soccer.
    We have much homework to do every day.
    Most students think so.

    Few 和little意为“几乎一点没有”,具有否定意义。
    例如:He has a few friends here.
