exit.,A.wouldn,t,B.needn,t,C.couldn,t,D.mustn,t,解析,句意为：你不准把车停在这里！这是一个紧急出口。,wouldn,t,不会；,needn,t,没有必要；,couldn,t,不能够；,mustn,t,不准，禁止。故选,D,项。,答案,解析,方法,2,句型判断法,有些情态动词需要用在特定的句型中，如,may,表示推测时，往往用在肯定或否定句中；,must,表示推测只能用于肯定句中。运用此法就是通过分析所给句子的句型特点，选用具有特定句型特点的情态动词。,典例,You _ be hungry alreadyyou had lunch only two hours ago!,A.wouldn,t,B.can,t,C.mustn,t,D.needn,t,解析,句意为：你不可能饿了。你两小时前刚吃过。,can,表推测用于否定句中，意为,“,不可能,”,。,答案,解析,方法,3,语气判断法,情态动词主要表示说话人的语气、情感或态度，所以在解答此类试题时，一定要注意说话者的语气,(,这也是解题的难点,),，这就要求正确理解句子，从说话者的角度去考虑问题，结合具体的语境来分析和判断，最后确定所需情态动词是否符合特定的情感需要。,典例,Just as we were sitting down to have dinner,，,the telephone _,ring.,A.must,B.could,C.might,D.need,解析,must,在此表示说话人的愿望或感到不耐烦，意为,“,偏要,”,。句意为：正当我们要坐下来吃饭时，偏偏电话铃响了。,答案,解析,方法,4,人称判断法,有些情态动词在表达某个意义时，要与特定的人称连用，这为我们选择正确答案提供了方向。,典例,I haven,t got the reference book yet,，,but I,ll have a test on the subject next month.,Don,t,worry.You,_ have it by Friday.,A.could,B.shall,C.must,D.may,解析,句意为：,我还没有弄到参考书，但是下个月我将参加这门学科的测试。,不要担心，到星期五时你就有了。,shall,用于主语为第二、三人称的陈述句中，表示,“,允诺,”,，符合语境。,could,能够；,must,必须；,may,也许，可以。,答案,解析,方法,5,特定词汇、句型提示法,虚拟语气可以用在状语从句、名词性从句、定语从句中，在不同的从句中，虚拟语气用不同的动词形式来体现，如,if,非真实条件句,(,分三种情形,),，,wish,后的宾语从句等。所以，掌握了各类从句中虚拟语气的动词形式，就基本上掌握了虚拟语气的用法。另外，某些词、句如,if it were not for/had not been for,，,but for.,，,if only.,，,without,等，往往也要采用虚拟语气。,典例,1,If it _ for his invitation the other day,，,I should not be here now.(2016,江苏，,27),A.had,not been,B.should,not be,C.
