知识梳理
Language points
1．Can you...？意为“你能……吗？”，此句型表示客气地邀请某人做某事。
can是情态动词，意为“能；可以”，其后接动词原形。
can可以用could替换。区别在于：用could比用can语气更委婉，显得更有礼貌，而can则较口语化。
该句型中Can you...？的肯定回答一般为Sure，I'd love/like to.；
否定答语中常用Sorry代替No，以示礼貌，即Sorry，I can't.或I'm sorry，I'd like/love to，but...。
eg：—Can/Could you go shopping with me？
你能和我一起去购物吗？
—Sure，I'd love to./Sorry，I can't.I have to do my homework.
当然，我很乐意。/抱歉，我不能去，我得做作业。
2．prepare动词，意为“使做好准备；把……准备好”。常用于以下结构中：
①prepare for为……做准备
②prepare sb. sth.为某人准备某物
③prepare to do sth.准备做某事
④prepare sb. for/to do sth.使某人为……做好准备
3．go to the doctor “去看医生”，为动词短语，相当于go to see a doctor。
4．have the flu患流感
“have＋a/an＋疾病名称”，意为“得了……病”。
【拓展】have a cold感冒
have a fever发烧
have a headache头痛
【注意】flu前不用a，而用the。

情态动词can
情态动词can，“能；会”，表示说话人的语气或情态，没有人称和数的变化，在句子中不能常独作谓语，其后须跟实义动词原形。

—Can you come to my birthday party tomorrow？
—Sorry，I am afraid not.I'm going to visit my grandpa.
情态动词must
must，“必须，不得不”，强调说话者主观上认为必须做某事，含有“主观判断”的意味。
eg：I must get up at 6 o'clock every morning.
我每天早上必须六点钟起床。
have to的用法
“have to”意为“不得不，必须”，强调客观上需要，即外界条件的需要不得不做某事，含有“形势逼迫”的意味；有单、复数及时态的变化，其第三人称单数为has to，过去式为had to。
eg: His mother is ill.He has to stay at home and look after her.

have to 与must的区别：
①have to意为“不得不；必须”，它强调一种客观情况。must意为“必须”，着重于说话人主观上认为有义务、有必要。
eg: We have to go home now because it's dark.
我们现在必须回家因为天黑了。
