情态动词技巧
一、情态动词试题的突破方法：(1) 首先从整体上把握情态动词的语法和语义特征。
(2) 逐个学习，了解每个情态动词的用法特征，尤其要熟练掌握一些常用或常考情态动词的基本用法并认真区别具有相同功能的、意思相近的情态动词的用法。
(3) 收集并熟练掌握真实的口语材料和近几年高考有关情态动词的试题，在真实的语境中去体会、领悟、印证、掌握情态动词的用法特征和常见考点。
二、情态动词的解题技巧：(1) 认真审题，结合所给出的语境，正确把握说话者的语气、情感、态度、观点等。
(2) 认真思考所给选项中情态动词的基本特征和用法，并结合语境推敲答案。
(3) 要注意把握时间概念。
情态动词无论是表达“推测和可能性”，还是表达“虚拟”这一概念，只要是对过去已经发生的事情进行描述，一律用“情态动词+have done”这一结构；对现在或将来的事情进行描述，用“情态动词+动词或系动词原形”。
例如：（NMET2008山东，24）Thank you for all your hard work last week. I don’t think we ______ itwithout you.A. can manageB. could have managedC. could manageD. can have managed根据题干中所给出的时间last week可知我们已经做完了工作，已经完成，故排除A、C两项，再结合could have done表示虚拟语气以及与前面的I don’t think…，故说话者想表达的意思是：离开了你，我们本不可能完成这项工作。
故答案为B项。
三、情态动词用法归类与高考试题分析：（一）表示推测的情态动词对现在或将来情况推测，用情态动词+do / be / be doing…；对过去的推测，用情态动词+have done / been…；表示肯定推测的情态动词按可能性大小依次为 must, should /ought to, may, might, could；否定推测，常用can’t / couldn’t，译为“根本不可能”、“想必不会”，表示推测的语气非常肯定，may not, might not或could not译为“可能不”、“也许不”，表示推测的语气不很肯定。
情态动词用法归纳
情态动词用法归纳情态动词表示说话人对动作或状态的各种观点和态度，如需要、猜测、意愿、怀疑等。
有can (could), may (might), must, have to, shall (should, will (would), dare (dared), need (needed), ought to 等。
情态动词无人称和数的变化；不能单独使用，必须与其后的动词原形构成谓语一、 can, could1)表示能力（体力、知识、技能）。
Can you lift this heavy box?（体力）Mary can speak three languages.（知识）Can you skate?（技能）此时可用be able to代替。
Can只有一般现在时和一般过去式；而be able to则有更多的时态。
I’ll not be able to come this afternoon.当表示“经过努力才得以做成功某事”时应用be able to，不能用Can。
He was able to go to the party yesterday evening in spite of the heavy rain.在谈论说话时发生的动作，用can,不用be able to.Look!I can swim.Could经常和动作see,hear,smell,taste,feel,remember,understand等连用。
When we went into the house,we could smell something buring.2)表示请求和允许。
-----Can I go now?----- Yes, you can. / No, you can’t.此时可与may互换。
在疑问句中还可用could, might代替，不是过去式，只是语气更委婉，不能用于肯定句和答语中。
---- Could I come to see you tomorrow?---- Yes, you can. ( No, I’m afraid not. )3)表示客观可能性（客观原因形成的能力）。
