一)、非推测性用法-考察词义辨析1.词义及用法;2.同义区分;二)、推测性用法-考察可能性的强弱1.类型2.比较强弱二.用法

拖儿带女型will(would)将；愿意；邀请（用于疑问）can(could)能,可以

Shall将会;必须;应该(用于第一人称,征求意见)(should)将会;必须;应该;(间接引语,征求意见),竟然may可以;祝愿(might)可以一)、非推测性用法1.词义及用法:独门独户型must必须oughtto本该一心两用型deed需要dare敢

区分1基本用法:could，would，might，should是四个独立的情态动词，只有在直接引语变成间接引语时作为will，can,shall,may的过去时代用一下Shallwebeginnow?Heaskedifweshouldbeginnow?2.同义区分

区分2:社交口语中，同义情况下，would,could,should,might比原型更委婉、礼貌。你今晚来吗？你能帮我吗？?你或许能帮我个忙吧?Wouldyoucometonight？Couldyouhelpme?Youmightdomeafavor?

一般上指“自己允许别人做某事”（may较正式）canmay同义，语气较委婉couldMight区分3—请求许可--Can/May/Could/MightIuseyourdictionary?--Yes,youcan.(No,Iamafraidnot/Yes,please./Thanks)

May引导问句，肯定回答，Yes,ofcourse./Yes,certainly./Sure否定回答:No,youmustn’t（不准）.No,youneedn’t.No,youcan’t.Must引导问句，（must与haveto意思大致相同）肯定回答:must否定回答:Needn’t/Don’thaveto.

区分4—建议请求Will多用第二人称疑问句；Would（will的过去式，委婉）Shall多用第一人称疑问；Should(间接引语)；Can/may多用第一人称疑问，“求得认可”
