典型陷阱题分析
典型陷阱题分析
1. ---Don’t you believe me？---______, I’ll believe _______ you say.
A. No; whatever
B. Yes; no matter what
C. No; no matter what
D. Yes; whatever
【陷阱】容易误选A。
【分析】答案选D。在回答否定疑问句时，要特别注意yes, no 的正确理解。回答yes 时，可视为yes, I do 之类的省略形式；回答no 时，可视为no, I don’t 之类的省略形式。针对问句”其答句“Yes, I do” 的实际意思便是“不，我相信你”，这与I‘ll believe whatever you say 的意思完全吻合。注意，no matter what只能引导让步状语从句，不能引导宾语从句。
2. ---Would you mind if I _______ one of these books？---_______.
A. took; Certainly not
B. take; Yes, of course
C. can take; Yes, please do
D. may take; No, I‘m using it
【陷阱】几个干扰项均有可能误选。
【分析】最佳答案选A。做对此题要注意两点：一是would you mind 后接if 从句时，从句谓语通常要用一般过去时（但Do you mind if 后的谓语不用过去式）；二是对would you mind… 的回答实际上是对mind（介意）的回答，即肯定回答表示“介意”，否定回答表示“不介意”。
（1）---Do you mind if I smoke here？
---_______. Go to the smoking room, please.
A. Of course not
B. Sure, why not
C. No, I don’t
D. Yes, I do
（2）“________, sir？” “No. Go ahead.”
A. May I use your dictionary
B. Do you mind if I use your bike
C. Would you mind opening the window
D. May I have a look at your new book
3. ---Haven’t seen you for ages！Do you still work in Guangzhou？
---_______. It’s two years since I worked there.
A. Yes, I have
B. Yes, I do
C. No, I haven’t
D. No, I don’t
【陷阱】几个干扰项均有可能误选。
【分析】答案为D。首先要正确理解It‘s two years since I worked there 的意思。按英语习惯，since用作连词时，它所引导从句的谓语通常应是非延续性动词，若为延续性动词或状态动词，则它所表示的动作或状态的应是其完成或结束（而不是其开始）。
请翻译下列句子：
I haven’t heard from him since he lived in Beijing.
正译：自从他离开北京以来，我一直未收到他的信。
误译：自从他住在北京以来，我一直未收到他的信。
He has never come to see me since I was ill.
正译：自我病愈以来他还没来看过我。
误译：自我生病以来他还没来看过我。
由此可见，上面一题中It‘s two years since I worked there 的实际意思是“我没在那儿工作已有两年了”。弄清此句的意思后，再结合上下文的语境，答案选D就不难理解了。
（1）---How do you like the food in this restaurant？
---Oh, _____. We couldn’t have found a better place.”
A. too bad
B. sorry
C. wonderful
D. impossible
答案选C。We couldn’t have found a better place 的实际意思是“这是我们所能找到的最好的地方”，
（2）---How do you like the food in this restaurant？
---Oh, ____. We couldn’t have found a worse place.”
A. too bad
B. sorry
C. wonderful
D. impossible
答案选A。此题与上面一题仅差一词，即将better 改成了worse. We couldn’t have found a worse place ，其意是说“我们不能找到一个比这个地方更好糟的地方了”，言外之意，“这是最糟的地方”。
2008各地高考题
1．---Have you been wasting time on computer games again?
---_____. I’ve been studying a lot and I need a break.
A. No way
B. Not really
C. I don’t agree
D. I couldn’t agree more
答案：B。根据下一句“我一直在学习，我需要休息一下”可知，此处应是“我没有浪费时间玩游戏。”Not really意思是“事实上不是、没有”，符合此处语境。No way 意思是“没门”；I don’t agree 意思是“我不同意”，表示绝句对方的提议；
I couldn’t agree more 意思是“我非常同意”，与所提供的情景矛盾。
2．---Could we see each other at 3 o'clock this afternoon?
---Sorry, let's make it _____time. （2008重庆卷）
A. other's
B. the other
C. another
D. other
答案： C 本题考查交际用语。根据上下文，another time 表示“下次，改个时间”。
3. ---May I ask a question after class, Sir?
--- ____, but not during my lunch break. （2008重庆卷）
A. I'm sorry
B. Anytime
C. Certainly
D. Go ahead
答案：C 本题考查交际用语。根据上下文表示“当然可以，不过不能在午饭期间”。
4. ---I'm afraid I can't return the book to you before Friday.
--- ____（2008重庆卷）
A. Don't be afraid
B. Be careful
C. Not at all
D. Take you time
答案：D 本题考查交际用语。根据上下文可以看出“没有关系，别着急；慢慢来”
5. --- Would you like to join us in the game?
---_____, for I have something important to attend to. (2008福建卷)
A. I will
B. I’d love to
C. I won’t
D. I’m afraid not
答案是D。考查交际用语的用法。从答句I have something important to attend to 来看，只有D项符合语境。
6. ---Shall we go out for dinner tonight?
---______. (2008浙江卷)
A. You are right
B. It must be funny
C. That sounds great
D. Have a nice time
答案：C。本题考查的是交际用语。本题第一句---Shall we go out for dinner tonight?实际上是一个表示建议的句子，而不是一般的疑问，这一点必须要特别引起注意。A项表示“你是对的”；B项表示“这肯定很有趣”；C项表示“听起来很不错”；D项表示“（祝你）玩得愉快”。根据四个选项可以判知，C项可用来对前一句表示赞同。
7. --- Is Peter there?
--- _____________, please. I’ll see if I can find him for you. (20008江苏卷)
A. Hold up
B. Hold on
C. Hold out
D. Hold off
答案：B 解析：本题考查的是打电话时的用语，"Hold on”意为“别挂”
8. --- Have you got any job offers?
--- No, I _____ (2008辽宁卷)
A waited B. had been waiting C. have waited D. am waiting
答案：D 此题考查时态与交际用语的结合，由句意可知：目前还在等待。故用现在进行时。
9. ---My name is Jonathan. Shall I spell it for you?
--- _____ (2008辽宁卷)
A lf you don’t mind B. Not at all C. Take it easy D. Nice to meet you 选A。情景交际用语，由语境可知。
10 ．---Would you like to join me for a quick lunch before class?
--- ___, but I promised Nancy to go out with her. （2008卷Ⅰ）
A. I’d like to
B. I like it.
C. I don’t
D. I will
答案：A。
【试题解析】从对话上文可知是回答对方的请求。I’d like to 与上文呼应。11．--- What fruit is in season now?
--- Pears and apples, ______（2008卷Ⅰ）
A. I know
B. I think
C. I see
D. I feel
答案B。对别人提出问题的发表自己的看法应用I think(我认为)
12．---Sorry, I made a mistake again.
--- ______. Practice more and you’ll succeed. （.2008卷Ⅰ）
A. Never mind
B. Certainly not
C. Not at all
D. Don’t mention it
答案A。Certainly not常用来回答别人问是否见意的问题；Not at all 和Don’t
mention it.用于别人致谢时的答语。只有Never mind符合语境。题意是“对不起，我又出错了。没关系，多练习，你就会成功的。”
13．---Say, Jane, will you come with me to the game Friday?
---_____, Bob, but I promised Mary I’d go with her.（山东卷）
A.My pleasure
B. Thanks
C. Take it easy
D. Forget it.
答案：B 对于对方的邀请表示感谢病并委婉拒绝。情景对话要从礼貌出发。My pleasure 相当于It’s my pleasure,用于回答对方的感谢.Take it easy意为：别着急，慢慢来。Forget it意为：算了吧，别再提了，常用于回答别人的感谢和道歉。
14．---I have some big news for you. You’ve been accepted as a member of our club.
---_______ That’s great! （安徽卷）
A. Have I ?
B. Pardon?
C. Congratulations!
D. Good idea!
答案A。选项A. Have I?是Have I been accepted as a member of our club?的省略。在有清晰的上下文的情况下，口语中尽量使用简洁的表达。选项B. Pardon?用于请求别人重复说过的话；选项 C. Congratulations!用于祝贺别人取得的成绩；选项D. Good idea!用于对别人的建议表示赞同。
15. ---Good evening. Huangshan Hotel.
---Good evening. _____?（2008安徽卷）
A. Do you still have a room for tonight
B. What would you like, please
C. Is there anything I can do for you
D. Who is that speaking, please
答案A。本题考查语言的交际功能。从题意看，对话的双方分别是旅馆的服务员和顾客。四个选项中，只有选项A的交际功能才符合顾客的身份。
【解题思路】本题题干中Huangshan Hotel是解题的关键，从中看出对话双方的身份，从而容易理解对话内容。
---I think you’d better type this letter again before Mr. Smith see it.
--- Oh, dear! _____（2008江西卷）
A. Who cares?
B. No problem
C. I don’t mind at all
D. Is it as bad as that?
答案：D 本题考查情景交际。由“我想你在Mr. Smith 看到之前应该把这封信再打印一次” “哦，真的吗？——” 可知对方对此不以为然。Is it as bad as that? ( 有那样糟吗？)其中A项Who cares ( 谁在乎？) 不礼貌。
17. ---- Are you all right ? ---- ______.
AThat’s OK B. I think so C. Take it easy D. It’s very kind of you
答案：B。本题考查的是交际用语中so指代一个肯定的宾语从句的用法，在这里so指代I’m all right。对于这种题型，考生在复习时应该特别注意加强对中西方文化知识的比较和了解，掌握使用地道的英语表达习惯来交流思想、传递信息。

No, I _________ to bring it. A.forget, forget B.forgot, forgot C.forget, forgot D.forgot, forget 答案选C，理由同上。 2.Dear me! Just _________ at the time! I _________ no idea it was so late. A.look, have B.looking, had C.look, had D.looking, have 【陷阱】此题容易误选D，认为第一空用现在分词表伴随，第二空填have 的一般现在时，以保持与前面时态的一致性。 【分析】其实，此题应选C，第一空应填look, 因为这是祈使句的谓语；第二空应填had，因为前一句说“看看时间吧”，这一看当然知道了现在很迟的情形，“不知道这么迟了”显然应是“过去”的事，故应用一般过去时态，许多同学由于忽略这一隐含的语境而误选。 3.Mr Smith _________ a book about China last year but I don’t know whether he has finished it. A.has written B.wrote C.had written D.was writing 【陷阱】容易误选B或C。 【分析】此题应选D，这是由but I don’t know whether he has finished it 这一句话的语境决定的，全句意为“史密斯先生去年在写一本书，但我不知道他现在是否写完了”。有的同学可能由于受last year的影响而误选B。但若选B，则句子前半部分的意思则变为“史密斯先生去年写了一本书”，既然是“写了”，那么这与下文的“但我不知道他现在是否写完了”相矛盾。 4.He has changed a lot. He _________ not what he _________. A.is, is B.was, was C.is, was D.was, is 【陷阱】几个干扰项均有可能误选。 【分析】最佳答案选C，上文说“他”变化很大，即“他”现在不是过去的那个样子了，故第一空填is，第二空填was（其实第二空也可用used to be）。请看类例： 北京市西城区五年级（上）易错易混100填空题题精粹word含答案 一、填空题 1．在○里填上“＞”、“＜”或“=” ,0.78÷0.99○0.78 7.8×1.3○7.8 9.027○90.27×0.1 2．丁丁买了4盒铅笔，每盒元，付给售货员20元，应找 回（________）元。 3．某城市一天早晨的温度是m℃，中午比早晨的温度的2倍还高5℃，这个城市这天中午的气温用字母表示是（______）℃。如果这天早晨是8℃，那么中午是（______）℃。 4．盒中有10朵黄花，3朵红花，1朵白花，从中摸出1朵，摸到（______）花的可能性最大，摸到（______）花的可能性最小。 A.红 B.黄 C.白 5．9.8除以22的商用循环小数表示是（______），保留两位小数是（______）。 6．盒子里有红、黄、蓝、绿、白、黑球各一个，从中任意摸出一个，有（______）种可能结果；从中任意摸出两个，有（______）种可能结果。 7．一个平行四边形和一个三角形等底等高，它们的面积和是 ，则平行四边形的面积是（______） 。 8．美术课上，陈冬坐在美术教室的第5列第4行，用数对（5，4）表示。李明坐在陈冬正前方的第一个位置上，李明的位置用数对表示是________。 9．如果4+5=25，那么 3+4=（____）。 10．0.3的8倍是（________）；30里面有（__________）个0.6。 11．每千克西红柿x元，奶奶买6千克西红柿应付（_______）元，付给售货员1张100元的人民币，应找回（______）元。 12．近似数4.9和4.90完全相同．_____ 【经典例题】 【例1】（2012湖北）如图，在圆心角为直角的扇形OAB 中，分别以OA ，OB 为直径作两个半圆．在扇形OAB 内随机取一点，则此点取自阴影部分的概率是 A ．1- 2π B ． 12 - 1π C ． 2π D ． 1π 【答案】A 【解析】令OA=1，扇形OAB 为对称图形，ACBD 围成面积为S 1，围成OC 为S 2，作对称轴OD ，则过C 点．S 2即为以OA 为直径的半圆面积减去三角形OAC 的面积，S 2= π2 ( 12 )2- 12 × 12 × 12 = π-28 ．在扇形OAD 中 S 12 为扇形面积减去三角形OAC 面积和 S 22 ， S 12 = 18 π×12- 18 - S 22 = π-216 ，S 1+S 2= π-24 ，扇形OAB 面积S= π4 ，选A ． 【例2】（2013湖北）如图所示，将一个各面都涂了油漆的正方体，切割为125个同样大小的小正方体，经过搅拌后， 从中随机取一个小正方体，记它的涂漆面数为X ，则X 的均值E(X)＝( ) A. 126125 B. 65 C. 168125 D. 75 【答案】B 【解析】X 的取值为0，1，2，3且P(X ＝0)＝27125，P(X ＝1)＝54125，P(X ＝2)＝36125，P(X ＝3)＝8125，故E(X)＝0× 27 125＋1×54125＋2×36125＋3×8125＝6 5 ，选B. 【例3】（2012四川）节日前夕，小李在家门前的树上挂了两串彩灯，这两串彩灯的第一次闪亮相互独立，且都在通电后的4秒内任一时刻等可能发生，然后每串彩灯以4秒为间隔闪亮，那么这两串彩灯同时通电后，它们第一次闪亮的时刻相差不超过2秒的概率是( ) A. 14 B. 12 C. 34 D. 78 【答案】C 【解析】设第一串彩灯在通电后第x 秒闪亮，第二串彩灯在通电后第y 秒闪亮，由题意? ????0≤x≤4， 0≤y≤4，满足条件的关系式 为－2≤x－y≤2. 1.
