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）Isntittimeyougotdownto___thepapers？
A.markB.bemarked C.beingmarkedD.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getdowntodoingsth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,coffeelovers!Wehaveforyou,thebestcoffeemachine___invented.
A.everB.alreadyC.evenD.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Wehavethebestcoffeemachine___invented，而分词短语everinvented=whichhaveeverbeeninvented是定语修饰语；foryou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）Youcantimaginewhatdifficultywehad______homeinthesnowstorm.
A.walkedB.walkC.towalkD.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havesomedifficulty（ｉｎ）doingsth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）—Whichdriverwastoblame？—Why,____!Itwasthechildsfault,clearandsimple.Hesuddenlycameoutbetweentwoparkedcars.
A.bothB.eachC.eitherD.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whichdriverwastoblame而忽略thechildsfault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）—Imdeadtired.Icantwalkanyfurther,Jenny.—____,Tommy.Youcandoit.
A.NoproblemB.Nohurry C.ComeonD.ThatsOK
【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Comeon,youcandoit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。
