为高考英语单选易错题“开处方”

　　单项选择是英语高考的一个必考题型。单选题不是单纯地考查“纯语法”或“纯词汇”，而是在特定的语言环境中考查考生综合运用语言的能力。

　　易错点一  思维定势干扰

　　典例1  （2007年重庆卷）  Isn’t it time you got down to ___ the papers?

　　 A. mark              B. be marked　　C. being marked       D. marking

　　【命题意图】  介词to与不定式符号to辨析

　　【 解题思路】  正确答案为D。考生易误以为考查动词不定式结构而选A。其实本题考查短语get down to doing sth的用法，意思是开始认真对待某事。

　　【失误警示】  思维定势是指在长期的思维过程中所形成的一种固定的思维模式。运用得当，它可以帮助考生在短时间内调集解决问题所需的相关知识进行分析、推理，并得出正确的答案；运用不当，便会误导考生，使其掉入命题人预设的陷阱。

　　易错点二  冗余信息干扰

　　典例2  （2007年江西卷）

　　Attention, coffee lovers! We have for you, the best coffee machine ___ invented.

　　 A. ever   B. already   C. even    D. nowadays

　　【命题意图】  特定语境中的副词辨析

　　【解题思路】  正确答案为A。本题的主体句是We have the best coffee machine ___ invented，而分词短语ever invented = which have ever been invented是定语修饰语；for you不影响主体句答案的选择。

　　【失误警示】  常见的冗余信息有插入语、后置定语、前置状语、从句等。对于此类题目，考生可以反其道而行之，去掉冗余部分，这样，答案就会一目了然。

　　易错点三  被表面现象迷惑

　　典例3  （2007年辽宁卷） You can’t imagine what difficulty we had ______ home in the snowstorm.

　　A. walked   B. walk   C. to walk    D. walking

　　【命题意图】  英语固定句型的用法

　　【解题思路】  正确答案为D。把题干还原，很容易看出，本句使用的是have some difficulty （ｉｎ） doing sth这个句型。

　　【失误警示】  单项填空题中，命题人常常变化一些常见的短语或句法结构，使答题者不容易分辨。此种手段常导致考生机械地套用语法，进而作出错误的选择。做此类题目时要注意学会转换和还原，使之清晰明了。

　　 易错点四  忽视有效附加信息

　　典例4  （2006年北京卷） —Which driver was to blame? —Why, ____! It was the child’s fault, clear and simple. He suddenly came out between two parked cars.

　　 A. both   B. each    C. either    D. neither

　　【命题意图】  特定语境中不定代词的辨析

　　【解题思路】  正确答案为D。本题若只注意到whichdriver was to blame 而忽略the child’s fault就会误选答案B或A。而最后一句表明，是小孩从两辆停着的车子中冲出，导致事故。

　　【失误警示】  单项填空题的空白后有时附带一些文字信息，这些信息千万不能忽视，它们并非总是冗余信息。判断依据是，有此信息与无此信息句子意义完全不同。

　　易错点五  受母语干扰

　　典例5  （2007年江西卷）—I’m dead tired. I can’t walk any further, Jenny.  —____, Tommy. You can do it.

　　 A. No problem     B. No hurry　   C. Come on        D. That’s OK

　　【命题意图】  交际用语的用法

　　【解题思路】  正确答案为C。易误选A或D，因为汉语里常用“你会没问题的，你能行的”来安慰他人，但英语中通常用Come on, you can do it来鼓励他人。

　　【失误警示】  由于母语在大脑中的根深蒂固，所以常常会对外语学习者大脑中尚不牢固的外语知识产生负面影响。命题者常利用这一点，制造陷阱。
