—情态动词英语·新课标(RJ)┃重点解读┃专题复习一┃ 重点解读 一、情态动词的一般用法
表示说话人的语气、情态,后跟动词原形,不能独立作谓语,无人称和数的变化。 情态动词有:can (could), may (might), must, need, shall (should), will (would)。这里主要讲解以下几点:
1.can (could) 表示“说话人能够, 可以, 同意, 准许, 以及
客观条件许可”, could 为 can 的过去式。如:英语·新课标(RJ)专题复习一┃ 重点解读Can I use your bike?
我可以使用你的自行车吗?
Could you help me?你能帮助我吗?
注意: can 和could 只能用于现在和过去两种时态, 将来时态用 be able to 来表示。    英语·新课标(RJ)专题复习一┃ 重点解读2.may (might) 意为“可以”, 表示说话人同意、许可或请求
对方许可。如:
May I use your pen? 我可以用你的钢笔吗?
You may put on more clothes.你可以多穿衣服。
might 是may 的过去式, 有两种用法, 一种表示过去式,一种表示虚拟语气, 使语气更加委婉、客气或对可能性的怀疑。如:
Might I borrow some money now? 我可以借点钱吗?
He might be alive. 他可能还活着。英语·新课标(RJ)专题复习一┃ 重点解读3.must 意为“必须, 应该, 一定, 准是”,表示说话人认为
有必要做某事。must 用在一般现在时和一般将来时中,过
去时中可用 have to 的过去式代替。如:
I must finish my work today.
我今天必须完成我的工作。
You mustn't work all the time.
你不能老是工作。英语·新课标(RJ)专题复习一┃ 重点解读注意: 在回答由must 引导的问句时,肯定回答用must,否定回答用needn't或don't / doesn't have to。如:
—Must I go home now?
—No, you needn't./Yes, you must.
“我必须现在回家吗?”
“不,你不必。”/“是的,你必须回家。”英语·新课标(RJ)专题复习一┃ 重点解读4.need 作情态动词, 表示 “需要、必须”。主要用于否定
句和疑问句中,否定形式为needn‘t,表示“没有必要、不
必”。用need 提问时,肯定回答为must,否定回答为
needn't。如:
—Need we do some cleaning now?
—Yes, you must./No,you needn't.
“我们现在需要打扫卫生吗?”
“是的,你们必须打扫。”/“不,你们没必要。”英语·新课标(RJ)专题复习一┃ 重点解读 need 还可作实义动词用, 这时 need 结构为 need to do sth。如:
I need to learn more.
我需要学习更多。
All you need to do is to complete this form.
你需要做的就是填好这个表格。英语·新课标(RJ)专题复习一┃ 重点解读二、情态动词表推测
情态动词中的must, can, could, may, might都可表推测。其中must的可能性最大,can/could次之,may/might最小。
must的用法:
(1)表示推测“可能性”时,意思是“一定、准是”,语气较肯定,较有把握。如:
He must be an American.
=It is certain that he is an American.
他准是个美国人。英语·新课标(RJ)专题复习一┃ 重点解读(2)must表推测只能用于肯定句。如果要表示“一定不、肯定
不”的意思时,应用can't。如:
He must know my address.他肯定知道我的地址。(一定)
He can't know my address.
他肯定不知道我的地址。(一定不)
(3)must表示推测时,可以推测正在发生的动作或过去发生的
动作。如:
He must be at home now, for the light is on.
他现在一定在家,因为灯亮着。英语·新课标(RJ)┃专项训练┃专题复习一┃ 专项训练单项选择
