2014年版高考英语情态动词语法考点练习题目

情态动词考点 ‎◆典型陷阱题分析◆‎ ‎1. “Mike is often absent from class.” “Tell him he _____ answer for it if he goes on behaving like that.”‎ A. shall B. will C. would D. can ‎【陷阱】几个干扰项均有可能误选。‎ ‎【分析】最佳答案选A。shall 用作情态动词主要有以下两个用法：‎ ‎(1) 用于疑问句中征求意见。如：‎ Shall I help you? 要不要我帮帮你?‎ Shall I open the window? 要我把窗子打开吗？‎ ‎(2) 用于陈述句中表示允诺、告诫、警告、威胁、命令、规定、必然性等(可用于各类人称)。如：‎ You shall suffer for this. 你会为此事吃苦头的。(表威胁)‎ Each competitor shall wear a number. 每个参赛者要戴一个号码。(表规定)‎ You shall hear everything as soon as you come. 你一来就可听到所有情况了。(表允诺)‎ 请做以下试题(答案均选 shall)：‎ ‎(1) “I promise that she _____ get a nice present on her birthday.” “Will it be a great surprise to her?”‎ A. should B. must C. would D. shall ‎2. You _______ pay too much attention to your reading skill, as it is so important.‎ A. cannot B. shouldn’t C. mustn’t D. needn’t ‎【陷阱】几个干扰项均有可能误选。‎ ‎【分析】最佳答案选A。cannot…too…是英语中一个十分有用的表达，意为“不可能太……，无论怎样……也不算过分，越……越……”。如：‎ You can’t be too careful. 你越仔细越好。‎ You can’t praise the too much. 这本书值得大加赞扬。‎ We cannot work too much for the people. 我们为人民做工作是不可能做过头的。‎ A woman cannot have too many clothes. 女人买的衣服再多也不算多。‎ 注：有时也可用 can never, impossible 等与too连用来表示类似意思。如：‎ It is impossible to get there too soon. 去那儿越早越好。‎ ‎3. “Is John coming by train?” “He should, but he _____ not. He likes driving his car.”‎ A. must B. can C. need D. may ‎【陷阱】可能误选B或C。‎ ‎【分析】最佳答案为D。may 表推测，may not 意为“可能不(会坐火车来)”。句中的 He should 为 He should come by train 之省略，由于其后出现转折连词 but，说明语意有变化，再结合下文的 He likes driving his car，便可决定此题选D。注意，不能选B，因为can表示推测时通常不用肯定陈述句。‎ ‎4. “I heard they went skiing in the mountains last winter.” “It ____ true because there was little snow there.”‎ A. may not be B. won’t be C. couldn’t be D. mustn’t be ‎【陷阱】几个干扰项均有可能误选。‎ ‎【分析】此题最佳答案为C，主要由下文的 because there was little snow there 这一语境所决定，既然“没下什么雪”，那么“滑雪”就应是“不可能”，所以选 couldn’t be，即选C。‎ ‎5. “Do you think he is lazy?” “I _____ so once, but I don’t now.”‎ A. may have thought B. can have thought C. may think D. might think 答案选A。从答话人的语境可知，空格处的意思“曾经这样想过”，即对过去情况作推测，故应用“情态动词+动词完成式”；又因为 can 表推测不用于肯定句，故选A。请看类例：‎ Their answers are exactly the same — one of them ______ from the other.‎ A. must copy B. must have copied C. should copy D. should have copied 答案选B，既然两人的答案完全一样，说明“抄袭”已经发生，故用“情态动词+动词完成式”，根据句意，应选B而不能选D。‎ ‎6. You _____ be right, but I don’t think you are.‎ A. can B. could C. must D. should ‎【陷阱】几个干扰项均有可能误选。‎ ‎【分析】从语境上看，C、D不宜选，在剩下的A和B中，许多同学想当然地选了A，认为整个句子为现在时态，所以选can，而不选过去式 could，但是最佳答案却是B而不是A。按照英语语法，情态动词can 用于推测表示可能性时，通常只用于否定句或疑问句中，而不用于肯定句中；但 could 用于表推测时，却不仅可用于否定句和疑问句，也可用于肯定句，且此时的 could 并不是 can 的过去式，与 can 也没有时间上的差别，只是 could 比 can语气更委婉，所以答案选B。注：can 在以下特殊情况下，也可用于肯定句。一是表示抽象的可能性，即从理论上或逻辑上分析是可能的，但是实际上未必会发生。如：Anyone can make mistakes. 任何人都可能会犯错误。二是后接“be (get, seem, become)＋形容词”，表示“有时会”、“时常会”等。如：My father can be very unreasonable. 我父亲有时候很不讲道理。‎ ‎◆精编陷阱题训练◆‎ ‎1. “I thought you wouldn’t mind.” “Well, as a matter of fact I don’t, but you _____ me first.” ‎ A. should ask B. should have asked C. must ask D. must have asked ‎2. “I called you yesterday.
