Unit 3 Language in use
Period 1The river is too deep.
You ______ swim in it. mustn’tPresentation: Look at the pictures and make sentences with modal verbs:You
turn right.You stop!mustcan’tShe draw.canmust 必须
mustn’t 不准，不能can 能，能够
can’t 不能Betty ______ know what to do because she did some medical training. mustPresentation: Look at the pictures and make sentences with modal verbs:Let’s ask the policeman, he ______ know. couldThat boy ______ be Jim. He is at home now. can’tmust / could / can’t 在这些句子中表示猜测。 Grammar: Modal verbs(情态动词):情态动词是一种本身有一定的词义,表示说话人的情绪,态度或语气的动词,但不能单独作谓语,只能和其他动词原形构成谓语。
情态动词的基本特征：
情态动词+ 动词原形
eg： I can swim/sing/dance/jump.
2. 情态动词无人称和数的变化
eg： She/They/We/I can ride a horse.
3. 否定式构成是在情态动词后面加 "not"
eg：You can’t/mustn’t/needn’t play basketball. 情态动词must 的用法
表示主观的义务和必要，主要用于肯定句和疑问句，意思为 “必须……，得……，要……”；由must引起的疑问句，肯定回答要用must，否定回答要用needn’t，意思是“不必”；must的否定形式mustn’t表示禁止，意思是“不能，不许”。
e.g.—Must I finish the task right now?我必须现在就完成任务吗？
—No, you needn’t.不，你不需要。
You mustn’t come here without permission.
没有允许你不准来这。Grammar:2) 表示肯定的猜测，常用于肯定句中，
意为 “一定是，必然……”。
e.g. Your sister must be a doctor in this hospital.
( 现在的猜测 ) 你的妹妹现在一定在这家医院当医生。
He must be reading newspapers in the reading room now.
（正在进行的猜测）他现在肯定正在阅读室看报纸。Grammar:must 的用法have to 与must的区别
两都都表示“必须”，但must侧重于说话者的主观看法，认为有必要或有义务去做某事；have to侧重于客观需要，含有“不得不，被迫”之意。
e.g. All passengers must wear seat belts.
所有乘客都要系安全带。
My bike was broken yesterday, so I
had to walk to school. 昨天我的自行
车坏了，所以我只能走路去学校。Grammar:must 无人称和数的变化，而have to 则有多种形式。
eg：You will have to show your papers at the gate.
在大门口你得出示证件。
用于否定句时，must 的否定形式mustn't 意为“一定不要”“不允许”；而have to的否定形式don't have to 意为“不必”，相当于needn't。
eg：You mustn't tell him about it.
你一定不要告诉他这件事。(可能是秘密)
You don't have to tell him about it.
你不必告诉他这件事。(他可能知道了)have to 与must的区别Grammar:can的否定形式为cannot，缩写为can't。
1) 表示能力
e.g. I can’t swim. 我不会游泳。
Can you drive？ 你会开车吗？注意：
can表示能力可与be able to互换使用，且后者有更多的时态，be able to常被用来表示can所不能表示的将来或完成的概念。
e.g. They will be able to run this machine on their own in three months.
他们将在未来的三个月自己操作这个机器。Grammar:can 的用法2) 表示可能性，意思是：可以，可能。
e.g. That big cinema can seat 2,000 people. 那个大影院可以坐2000人。
He can be very friendly at times. 他有时可能非常友善。
3) 表示允诺，意思是：可以，能够。
e.g. You can have the book when I have finished it. 在我读完这本书后，你可以看。
Can I use your pen? 我能用下你的笔吗？
4) 表示惊异、不相信、猜测等（用于疑问句、否定句或感叹句中），意思是:会，可能。
e.g. This can’t be true. 这不可能是真的。
Can it be true？这能成真吗？can 的用法Grammar:一、我们已经学习的表推测的情态动词有：must/can/could
情态动词 can 和 could 表示“能够，可以”等意义的用法。can 和 could 还可以表示对现在或将来的推测，意为“会, 可能”，但 can 表示推测时，往往用于否定句和疑问句。用于疑问句时，can 比 could 表示的“可能性”要大；用于否定句时，can't表示“不可能”。例如：
You can't be serious!?你不是认真的吧！
could 则可用于肯定句、否定句和疑问句。在以下例句中，can 和 could 均表示可能：
He could be in pain.? 他可能很疼。
That could be harmful!?那可能有害！
Can/Could this be true?? 这有可能是真的吗 ?
情态动词must/can/could表示推测：二、表推测的三种句式：
1. 在肯定句中一般用must，can/could, 程度逐渐减弱。
e.g. He must/could know the answer to this question.
e.g. You have worked all this week. You must be tired.
2. 在否定句中用can’t(不可能)。
e.g. It can’t be the headmaster. He has gone to America.
3. 在疑问句中，一般只使用can/could。
e.g. Could he have finished the task?
e.g. Can he be at home now?情态动词must/can/could表示推测：Language practice That could be harmful!

祈使句表达说话人对对方的叮嘱、劝告、希望、禁止、建议、请求或命令等。
二、祈使句的特征：
以动词原形开头，无时态和数的变化。
三、祈使句的句型：
1. 动词原形构成的祈使句
通常省略主语 you，谓语动词用原形。祈使句的句首或句末有时加 please。否定句由 don’t 或 never 开头。例如：
Go downstairs, please! Don’t go downstairs, please!
Grammar:祈使句Grammar:祈使句2. let 构成的祈使句
由“Let + me/us/him/her + 动词原形”构成。这类祈使句往往用于请求允许（let us）或提出建议（let’s）。例如：
Let’s spend this weekend in the countryside.
Let him be here by ten o’clock.
① 以let开头的祈使句，如果后面跟第一、第三人称名词或代词的宾格，否定句在let前加don't。
eg：Don’t let me go with her tomorrow. 不要让我明天跟她一起去。
② 以let’s开头的祈使句，必须在let's后加not。
eg：Let’s not play computer games from now on.
从现在开始，我们不玩电脑游戏了吧。
Grammar:祈使句3. 无动词祈使句
在请求，命令和口号中，常用无动词祈使句，它实际上是省略了动词，从而使语句更简洁有力。例如：Just a minute, please! 请稍等！
在一些指示牌上，常用“No + 动名词/名词”构成省略的否定祈使句。
例如：No smoking! 禁止吸烟！
NO PHOTOS！禁止拍照！Grammar:祈使句 祈使句的反意疑问句，肯定祈使句的反意疑问部分用will you/won't you；
eg. Open the door, ?
否定祈使句的反意疑问部分用will you。
eg. Don’t stand near power lines, ？
但以let's开头的反意疑问部分用shall we。
eg. Let’s play baseball, ？will you/won't youwill youshall we 将下列句子改为否定句：Jump out of high buildings.
