Unit 9 Section A Grammar focus-3c 学案 (知识精讲+分层作业)
【词汇用法】
1.invite v. 邀请
invite 用作动词，意为“邀请”。常见用法有：invite sb. to do sth.
邀请某人做某事; invite sb. to sp.邀请某人去某地。
如：我最好的朋友邀请我参加她的生日聚会。
My best friend invited me to her birthday party.
昨天安娜邀请我看电影。
Yesterday Anna invited me to watch the film.
【拓展】invitation n. 意为“请柬；请帖；邀请” 与invitation相关的短语有：
make an invitation 发出邀请 accept an invitation 接受邀请
turn down/refuse/decline an invitation拒绝邀请
如：谢谢你的邀请。
Thanks for your invitation.
1) Lily received a warm welcome when she went into the classroom.
2) Yesterday, Jack received an invitation from Mark and accepted it happily.
accept v. 收到，接受
辨析：accept 与 receive
二者都含有“收到，接受”的意思。
accept意为“接受”，强调主观接受。
receive意为“收到；接到”，强调客观收到，但并不意味着同意接受。【注意】从搭配上说，在表示“接受教育、受到欢迎、得到支持、接待客人”等时，通常用receive。
refuse v.拒绝
refuse作动词，意为“拒绝”，与turn down/decline同义，与accept互为反义词。refuse to do sth. “拒绝做某事”。
如：Jenny礼貌地拒绝了我的帮助。
Jenny refused my help politely.
孩子们遇到困难时不肯放弃希望
The children refused to give up hope when in trouble.
4.have to 与 must
二者都有“必须”之意，但 have to 表示“客观上的需要”，有人称和时态的变化，否定形式为 don’t / doesn’t / didn’t have to (没必要)；must 表示“主观上的要求”，无人称和时态的变化，否定回答一般用 needn’t 或 don't have to (不必)。mustn’t 表示“禁止”。如：
You don't have to tell him about it.你不一定要把此事告诉他。
You mustn't tell him about it. 你一定不要把这件事告诉他。
—Must I be home before eight o’clock 8点之前我必须回家吗？
—Yes, you must. / No, you needn't. / No, you don't have to. 是的，必须回家。/不，不必。
【重点句型】
Can you ... 意为“你能……吗？”
该句型用于邀请别人或委婉地请求某人去做某事。其肯定回答常用 Sure, I’d love / like to. ，否定回答常用 I’m sorry, I can’t. / Sorry, I can’t. 等。如：
--- Can you go to the baseball game 你能去参加棒球比赛吗？
--- I’m sorry, I can’t. 对不起，我不能。
对于用情态动词can发出的邀请，回答时主要有两种情况：
接受：①Sure/Yes, I’d love(like) to. 当然，我愿意。②Sure/Of course. 当然。……
拒绝：①Sorry, I’m not available. 对不起，我没空。
②I’m sorry. I’m not free. I have to … 抱歉，我没空，我不得不……
③I’d love to, but I’m afraid I can’t. I must …我愿意，但是恐怕不行。我得……
