You _______ pay too much attention to your reading skill, as it is so important. <br />A. cannot B. shouldn’t <br />C. mustn’t D. needn’t <br />【陷阱】几个干扰项均有可能误选。 <br />【分析】最佳答案选 A。cannot&hellip;too&hellip;是英语中一个十分有用的表达，意为&ldquo;不可能太&hellip;&hellip;，无论怎 <br />样&hellip;&hellip;也不算过分，越&hellip;&hellip;越&hellip;&hellip;&rdquo;。如： <br />You can’t be too careful. 你越仔细越好。 <br />You can’t praise the too much. 这本书值得大加赞扬。 <br />We cannot work too much for the people. 我们为人民做工作是不可能做过头的。 <br />A woman cannot have too many clothes. 女人买的衣服再多也不算多。 <br />注：有时也可用 can never, impossible 等与 too 连用来表示类似意思。如： <br />It is impossible to get there too soon. 去那儿越早越好。 <br />3. &ldquo;Is John coming by train?&rdquo; &ldquo;He should, but he _____ not. He likes driving his car.&rdquo; <br />A. must B. can <br />C. need D. may <br />【陷阱】可能误选 B 或 C。 <br />【分析】最佳答案为 D。may 表推测，may not 意为&ldquo;可能不(会坐火车来)&rdquo;。句中的 He should 为 He should <br />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 <br />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。 <br />4. &ldquo;I heard they went skiing in the mountains last winter.&rdquo; &ldquo;It ____ true because there was <br />little snow there.&rdquo; <br />A. may not be B. won’t be <br />C. couldn’t be D. mustn’t be <br />【陷阱】几个干扰项均有可能误选。 <br />【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 <br />然&ldquo;没下什么雪&rdquo;，那么&ldquo;滑雪&rdquo;就应是&ldquo;不可能&rdquo;，所以选 couldn’t be，即选 C。 <br />5. &ldquo;Do you think he is lazy?&rdquo; &ldquo;I _____ so once, but I don’t now.&rdquo; <br />A. may have thought B. can have thought <br />C. may think D. might think <br />答案选 A。从答话人的语境可知，空格处的意思&ldquo;曾经这样想过&rdquo;，即对过去情况作推测，故应用&ldquo;情态动 <br />词+动词完成式&rdquo;；又因为 can 表推测不用于肯定句，故选 A。请看类例： <br />Their answers are exactly the same &mdash; one of them ______ from the other. <br />A. must copy B. must have copied <br />C. should copy D. should have copied <br />答案选 B，既然两人的答案完全一样，说明&ldquo;抄袭&rdquo;已经发生，故用&ldquo;情态动词+动词完成式&rdquo;，根据句意， <br />应选 B 而不能选 D。 <br />6. You _____ be right, but I don’t think you are. <br />A. can B. could C. must ...
