2.否定句中用can’t / couldn’t(不可能),may not/might not(可能不).(1)It can’t/couldn’t be the headmaster.He has gone to America.这不可能是校长,他去美国了.3.疑问句中用can/could (能……?).(1)Could he have finished the task?他可能把任务完成了吗?(2)Can he be at home now?他现在能在家吗?
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

学习啦在线学习网 (1)She must / may / might / could arrive before 5.5:00前她一定/可能/也许到.
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”.(1)He must / may / might / could be listening to the radio now.他一定/可能/也许正在听收音机.
学习啦在线学习网 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) 她本该出席你的生日晚会的,可是她得在医院照顾她妈妈.(6)Tom should not /ought not to have told me your secret,but he meant no harm.(虚拟) 汤姆本不该告诉我你的秘密,可是他并无恶意.

名词性从句
主语从句
学习啦在线学习网 作句子主语的从句叫主语从句.主语从句通常由从属连词that,whether,if和连接代词what,who,which,whatever,whoever以及连接副词how,when,where,why等词引导.that在句中无词义,只起连接作用;连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用,在从句中充当从句的成分.
宾语从句
名词从句用作宾语的从句叫宾语从句.引导宾语从句的关联词与引导主语从句表语从句的关联词大致一样,在句中可以作谓语动词或介词及非谓语动词的宾语.
表语从句
学习啦在线学习网 在句中作表语的从句叫表语从句.引导表语从句的关联词与引导主语从句的关联词大致一样,表语从句位于连系动词后,有时用as if引导.其基本结构为：主语 + 系动词 + that从句.例如：The fact is that we have lost the game.事实是我们已经输了这场比赛.That’s just what I want.这正是我想要的.
学习啦在线学习网 【注意】whether 可引导表语从句,但与之同义的if却通常不用于引导表语从句.
同位语从句
学习啦在线学习网 同位语从句说明其前面的名词的具体内容.同位语从句通常由that引导,可用于同位语从句的名词有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等.
