附记忆口诀：
情态动词之一　　否定may时 mustn’t，否定must（为）needn’t。祝愿句中只用 may，把握不大用might。如：May you succeed.　　
情态动词之二　　ought 、should两相通，语气ought to较重。该做没做用完成。　　“该做没做用完成”是说ought to、should的完成时表示本该做的事，实际没做，有责备意。如：You should have been here 10 minutes earlier.
情态动词之三　　情态need常否、疑，接完成时“本不必”；肯定should 、 must，动名、不定为实意。　　此段表述的是need的用法，情态动词need多用于否定句、疑问句，接完成时是“本不必做实际做了”，肯定句中用should 、 must 、have to来代替，后接动名词、不定式时已为实意动词，而非情态动词。如：The motorcycle needs to be repaired. Your hair needs washing badly. 　
情态动词之四　　条件、疑问与否定，dare to do表实动。　　此段表述的是dare的用法，情态动词dare多用于条件句、否定句、疑问句，dare to do表示实意动词。如：Who dare touch my teeth? He dared to do so.
情态动词之五shall：shall二三人称用，允诺、命令、要求加警告；shall问句表征询，一三人称用得妙
