He likes driving his car.”A. mustB. canC. needD. may【陷阱】可能誤選B或C?！痉治觥孔罴汛鸢笧镈。may 表推測，may not 意為“可能不(會坐火車來)”。句中的 He should 為 He should come by train 之省略，由于其后出現(xiàn)轉(zhuǎn)折連詞 but，說明語意有變化，再結(jié)合下文的 He likes driving his car，便可決定此題選D。注意，不能選B，因?yàn)閏an表示推測時通常不用肯定陳述句。4. “I heard they went skiing in the mountains last winter.” “It _ true because there was little snow there.”A. may not beB. wont beC. couldnt beD. mustnt be【陷阱】幾個干擾項(xiàng)均有可能誤選?！痉治觥看祟}最佳答案為C，主要由下文的 because there was little snow there 這一語境所決定，既然“沒下什么雪”，那么“滑雪”就應(yīng)是“不可能”，所以選 couldnt be，即選C。5. “Do you think he is lazy?” “I _ so once, but I dont now.”A. may have thought B. can have thought C. may thinkD. might think答案選A。從答話人的語境可知，空格處的意思“曾經(jīng)這樣想過”，即對過去情況作推測，故應(yīng)用“情態(tài)動詞+動詞完成式”；又因?yàn)?can 表推測不用于肯定句，故選A。請看類例：Their answers are exactly the same one of them _ from the other.A. must copyB. must have copiedC. should copyD. should have copied答案選B，既然兩人的答案完全一樣，說明“抄襲”已經(jīng)發(fā)生，故用“情態(tài)動詞+動詞完成式”，根據(jù)句意，應(yīng)選B而不能選D。6. You _ be right, but I dont think you are.A. can B. could C. must D. should【陷阱】幾個干擾項(xiàng)均有可能誤選。【分析】從語境上看，C、D不宜選，在剩下的A和B中，許多同學(xué)想當(dāng)然地選了A，認(rèn)為整個句子為現(xiàn)在時態(tài)，所以選can，而不選過去式 could，但是最佳答案卻是B而不是A。按照英語語法，情態(tài)動詞can 用于推測表示可能性時，通常只用于否定句或疑問句中，而不用于肯定句中；但 could 用于表推測時，卻不僅可用于否定句和疑問句，也可用于肯定句，且此時的 could 并不是 can 的過去式，與 can 也沒有時間上的差別，只是 could 比 can語氣更委婉，所以答案選B。注：can 在以下特殊情況下，也可用于肯定句。一是表示抽象的可能性，即從理論上或邏輯上分析是可能的，但是實(shí)際上未必會發(fā)生。如：Anyone can make mistakes. 任何人都可能會犯錯誤。二是后接“be (get, seem, become)形容詞”，表示“有時會”、“時常會”等。如：My father can be very unreasonable. 我父親有時候很不講道理。
