一、情态动词
1. 情态动词的定义
情态动词表示说话人对所述动作或状态的态度或看法。情态动词本身有词义，但不能独立作谓语，必须和动词一起构成谓语，在各种人称后都用同样的形式。
2. 情态动词的用法
(1)can的用法
①表示人或物本身所具有的能力，意为“能，能够，会”。eg:
Can you skate? 你会滑冰吗？
She can speak a little Chinese. 她能讲一点儿汉语。
②表示可能性，意为“可能会”，常用于否定句或疑问句。eg:
Can it be true? 那会是真的吗？
That can’t be Mary; she’s in hospital. 那不可能是玛丽；她住院了。
(2) could的用法
①could可以表示过去的能力，若表示现在的能力时，语气比can委婉。eg:
She couldn’t swim half a year ago. 她半年前不会游泳。
What a good idea! Maybe I could talk about English names.
你的想法太好！也许我能谈谈英国人的名字问题。
②表示礼貌，常用在疑问句中，意为“能，可以”，答语一般用can。
—Could I borrow your bicycle? 我可以借一下你的自行车吗？
—Yes, you can./ No, you can’t. 是的，可以。/不，不行。
③表示猜测、怀疑等态度，一般用于否定句、疑问句或感叹句中。对现在情况表示猜测时，could 比can更
不确定，其结构为“can/could+动词原形”；对过去表示猜测时，结构为“can/could+ have+过去分词”。eg: You could be right, I suppose.我想可能是你对。
Don’t worry. They could have just forgotten to phone. 别担心。他们很可能只是忘了打电话。

③表示客观不可能性。eg:
Take an umbrella with you. It may rain. 带上雨伞，可能会下雨。
(4) must的用法

许可，不准，禁止”。eg:
I must go to the bank to get some money. 我得到银行去取些钱。
Cars mustn’t park in front of the entrance. 入口处不得停放汽车。
②它在肯定句中，还可表示“推测”，意为“一定”。“must be”表示对现在某事的推测；“must have done”

You must be hungry after your long walk. 你走那么长的路，一定饿了吧。

eg: Does he need a bike? 他需要一辆自行车吗？
They need some help. 他们需要帮助。
(6) will和would的用法

②用在动词原形前面，表示加强语气。eg:

中考英语情态动词考点归纳与例析
中考英语情态动词考点归纳与例析 【重点讲解】 情态动词表示说话人对某一动作或状态的态度，表示“必须”、“可能”、“应当”、“必要”等。情态动词本身具有一定的意义，但词义不完全，不能独立作谓 语，只能和主要动词一起构成谓语。情态动词没有人称和数的变化，没有非谓语形式。 常见情态动词用法归纳： 1.can和could:can表示能力、可能，只用于一般现在时，过去时用could。 (比较：beableto可以用于多种时态。)但could表示提出委婉的请求，或在否 定，疑问句中表示推测或怀疑时，不表示时态。例如： CouldIhavethetelevisionon?我可以打开电视吗？ Hecouldn’tbeabadman.他不大可能是坏人。 2.may和might表示允许或请求。might表示推测时，不表示时态，只是表示可能性比may小。 3.may(might)have+donesth的意思是“可能已经做了某事”，推测在过去时间里可能 发生的事情。例如： Hemay(might)havebeenhurtseriouslyinthecaraccident. 4.must和haveto都是“必须”的意思。haveto表示客观的需要，must表示说话人主观 上的看法，既主观上的必要。haveto有人称、数、时态的变化，而 must只有一种形式。另外，must用在肯定句中表示较有把握的推测，意为“一定”。 否定推测用can't。 5.musthave+donesth表示对过去可能发生的事情的推测，语气较强，具有“肯定”， “谅必”的意思。例如： --Lindahasgonetowork,butherbicycleisstillhere. --Shemusthavegonebybus. 6.should和oughtto都是“应该”的意思，可用于各种人称。 7.oughttohavedonesth/shouldhavedonesth表示本应该做某事，而事实上并没有做。否定句则表示“不该做某事而做了”。另外，oughtto在语气上比should要强。例如：Yououghtto(should)havebeenmorecarefulinthisexperiment. Heoughtnottohavethrowntheoldclothesaway. 8.need和dare既可用作实义动词用，又可用作情态动词用。作为情态动词，两者都只能用于疑问句，否定句和条件句中。 9.needn'thavedonesth表示“本没必要做某事”。例如： Idressedverywarmlyforthetrip,butIneedn'thavedoneso.Theweatherwas hot. 1
