Unit Three Be a Nice Person 专题02 语法提升·易错题专项训练 · 内容导航 · 1.Can you...? 用于口头求助请求 2.May I...? 委婉请求借用物品 3.Could you / Would you please...? 非常客气的请求 4.致歉与应答 I'm sorry / That's OK 5. 综合训练 高频易错点、易错点提示、小练笔、答题点拨 易错精讲 Can you...? 用于口头求助请求高频易错点01 一、概念 “Can you + 动词原形?”是口语最常用的求助句式，翻译为“你可以……吗？”，用于向熟人、同学寻求帮助；can是情态动词，情态动词后必须接动词原形。 二、句型结构： 结构 例句 一般疑问句：Can you + 动词原形 + 其他? 答句肯定：Sure./Yes, I can. 否定：Sorry, I can't. Can you help me? （你可以帮助我吗？） Yes, I can.（是的，可以。） 易错点提示 1.can后面动词必须用原形，不能加to、不能变三单 2.求助开头常用Excuse me铺垫，不能直接突兀说Can you...。 经典例题 —Excuse me, can you ____ your ping-pong bat to me? —Sure. A. lend B. lends C. to lend 点拨 答案：A 【解析】句意：打扰一下，可以把你的乒乓球拍借给我吗？当然可以。 情态动词can后接动词原形，因此选lend；B是第三人称单数形式、C带to，都违反can的用法，直接排除。 小练笔 01 一、用动词正确形式填空。 1. Excuse me, can you ____________ (open) the door for me? 2. Can you ____________ (fix) my bat? 3. Can you ____________ (get) some water? 4. Excuse me, can you ____________ (pass) the ruler? 5. Can you ____________ (find) my kite? 二、单项选择。 ( ) 6. —Excuse me, can you help me? —____ A. Sure B. Yes, I do C. No, I not ( ) 7. Can you ____ the window? A. closes B. close C. to close ( ) 8. —Can you get my bag? —Sorry, I ____. A. can't B. don't C. isn't ( ) 9. Excuse me, can you ____ me your pencil? A. show B. shows C. to show ( ) 10. Can you ____ down, please? A. to sit B. sits C. sit May I...? 委婉请求借用物品高频易错点02 一、概念： “May I + 动词原形?” 意为“我可以……吗”，用于请求借用物品，礼貌程度高于can，多用于向同学、长辈借东西；may同样是情态动词，后接动词原形。 二、句型结构： 结构 例句 问句：May I + 动词原形 + 物品? 肯定答：Yes, you may./Sure. Here you are.否定答：Sorry, you can't. May I use your bat?（我可以用用你的球拍吗？） 易错点提示 1.may后动词用原形，不能加to；主语是I，不用变换动词形式 2.答句不能用Yes, I may，问句主语是I，答句主语切换为you。 3. Yes, you may 仅书面使用，日常口语优先用 Sure / Here you are。 经典例题 ( ) —____ I use your crayon? —Sure, here you are. A. Do B. May C. Am 点拨 答案： B 【解析】句意：我可以用用你的蜡笔吗？当然可以，给你。请求借物品用情态动词may；do、am不能引导这类借物请求问句。 小练笔 02 一、选词填空 may / may not。 1. ____________ I borrow your kite? 2. —____________ I take this book home? —Sorry, you ____________. 3. ____________ I sit here? 4. ____________ I have a banana? 5. ____________ I look at your notebook? 二、单项选择。 ( ) 6. —May I use your eraser? —____ A. Here you are B. Yes, I am C. No, I can ( ) 7. May I ____ your scissors? A. take B. takes C. to take ( ) 8. May I ____ a look? A. has B. have C. to have ( ) 9. —May I come in? —____ A. Come in please B. Yes, I may C. No, I don't ( ) 10. May I ____ some paper? A. to get B. gets C. get Could you / Would you please...? 非常客气的请求高频易错点03 一、概念： “Could you please+动词原形?” “Would you please+动词原形?`”是礼貌等级最高的请求句式，用于麻烦别人做事，could、would不代表过去时，只是让语气更委婉；please可放句末或句中。 二、句型结构： 结构 例句 Could/Would you please + 动词原形 + 其他? 答句：Sure, no problem./Sorry, I can't. Could you please sweep the floor? （请帮忙打扫一下地板好吗？） Sure, no problem.（当然可以，没问题。） 易错点提示 1. please前后动词依旧是原形；很多同学误加to。 2. Could you please 否定结构直接在 please 后加 not。 经典例题 ( ) Would you please ____ the door? A. close B. closes C. to close 点拨 答案：A 【解析】句意：你可以关上门吗？would you please后接动词原形。 小练笔 03 一、用动词适当形式填空。 1. Could you please ________ (clean) the blackboard? 2. Would you please ________ (give) me a bowl? 3. Could you please ________ (wait) for me? 4. Would you please ________ (fetch 去拿) water? 5. Could you please ________ (stand) in line? 二、单项选择。 ( ) 1. —Could you help me? —____ A. No problem B. Yes, I could C. No, I would ( ) 2. Would you please ____ your pen? A. pass B. passes C. to pass ( ) 3. Could you please ____ talk loudly here?（否定） A. no B. don't C. not ( ) 4. —Would you open the window? —____ A. Sure B. Yes, I would C. No, I won't ( ) 5. Could you please ____ early? A. comes B. come C. to come 致歉与应答 I'm sorry / That's OK高频易错点04 一、概念： 做错事后用“I'm sorry”致歉；对方用“That's OK / Don't worry”安慰回应，属于情景交际固定搭配。 二、句型结构： 结构 例句 致歉：I'm sorry (for sth.) 回应：That's OK./It doesn't matter./Don't worry. 易错点提示 不能用You're welcome回应道歉，You're welcome用于回应Thank you。 经典例题 ( ) —I broke your bat, I'm sorry. —____ A. You are welcome B. That's OK C. All right, thanks 点拨 答案：B 【解析】句意：我弄坏了你的球拍，我很抱歉。没关系。回应道歉用That's OK；A用于答谢。 小练笔 04 一、选正确的应答句。A. That's OK. B. Don't worry. 1. Sorry I messed your book. ____ 2. I hurt your kite. ____ 3. Sorry I'm late. ____ 4. I broke your cup. ____ 5. Sorry I pushed you. ____ 二、单项选择。 ( ) 6. —I'm sorry. —____. A. That's OK B. You're welcome C.
