54、 )80.His hair _ white these days.A have turned B are C答案：1 B has been to 表示去过某地，但现在已回来。选项不符合题意。2. D 本题强调他妈妈开门的一瞬间他正在做什么，而非做了什么。B, C 选项不符合题意。3D How long ， for 均暗示本题应用完成时，且 die 为终止性动词，不能与 for+ 时间段连用， C 为干扰 项.4.C told , the next day 均暗示本题应用过去将来时, A 不符合题意, B 为干扰项。5.B 在 if 引导的条件状语从句中,要求主句为一般将来时,从句为一般现在时。

55、6.D said , never 均暗示本题应用过去完成时,而此题又强调主语从未去过日本。7.C 此题为客观真理,必须用一般现在时。8.C 本题表示发生在过去的丢车事件对现在造成步行上学的影响。9.A 到达会场发生在过去,人已离开又发生在到达会场之前。 应用过去完成时。本题中没有动作持续的 暗示,故不选 D.10.C since 引导的时间状语从句中,主句为现在完成时,从句应为一般过去时。11.D for 引导的时间段必须要用持续性动词。12.A 本题时态应为过去范畴,车开在先,人到在后,且 for 的出现标志从句动词应为持续性动词。13.B Shall we/I do sth是争求对方意见或

56、建议的常用句型,且 shall 只能用于第一人称 .14.A 本题为过去范畴,且不强调某一具体时刻的动作,所以选A.15.C 本题 look 暗示现在进行时态, every year 则表规律性动作,用一般现在时。16.D 与 How long 搭配应用持续性动词, keep 不是过去分词故选 D.17.C 与 for+ 时间段搭配应用持续性动词。18.C in+ 时间段用于将来时。19.D 本题 this evening 可考虑为将来的时间状语,故只能选D。20.A 与 for + 时间段搭配应用持续性动词。21.A 因过去多次去北京才导致了解该城市,而主句已为过去时,故选A。22.B 本题

57、为过去时,与动词持续性或终止性无关。23.C 本题为现在完成时第一种用法,与动词持续性或终止性无关。24.A 本题主句为祈使句,相当于一般将来时,谓语动词用一般现在时,故选A.25.C 本题 during his stay in Tokyo 表明动作发生在过去。26.B 根据从句中的谓语动词时态题示主句应为过去时,而不能单独看How often 。就用一般现在时。27.A 本题虽有 tomorrow，但因出现助动词 do，故不考虑将来时，且 want 具有将来色彩。28.D 本题最后一句出现 remembered,说明动作发生在过去，而去农场又发生在去工厂之前，且有for+时间段做时间状语，故

58、选 D。29.D 星期变化为客观规律，不是推测或打算。故选D 不选 A。30.B since 引导时间状语从句，主句为现在完成时，从句现为一般过去时。see 为终止性动词，但其否定形式可用于 since 引导时间状语从句中。31.C32.B33.C often ， always ， usually 等副词若与过去时间状语同时出现 , 则服从后者。34.D35.B for+ 时间段若与过去时间状语同时出现，则服从后者。故此两题用过去完成时。36.C 宾语从句的主句为过去时，但从句为客观真理，所以仍保留一般现在时.37.C as soon as 要求主句为一般将来时，从句为一般现在时。A fini

59、shed Bwill finish Chas finished DfinishA were having Bwas having Care having Dis havinghas turned Dwill behas gone to 表示去了某地，且现在还未回来。C、D( )78.Hehis homework and now is listening to music.38.B while 后面应跟着进行时态，而主句的 felt 则暗示过去范畴。39.C 本题易错选 B和 D,但后面的感叹句表明画画已成事实，且对现在产生影响。故选Co40C41B 此两题思路与 No 39. 相同，均应考虑过

60、去动作影响现在。42 B 本题必须用过去时态，但没有迹象表明动作的先后顺序，所以选B 不是 C。43 B 本题必须用过去范畴，但有迹象表明动作的先后顺序，电影放映在先，人随后到，且电影开演不必 用被动所以选 B。44 D 主句为祈使句， till 引导时间状语从句要求用一般现在时。45 A It is+ 时间段 +since 引导过去时为固定句型。46A since 引导时间状语从句，主句现在完成时 , 从句用一般过去时。与上句的固定句式不同。47 C for 前面应跟完成时和持续性动词。 get to do sth 属于终止性动词搭配。48 B in(during) the last(pas

61、t)+时间段用于现在完成时。49B by then 在这里理解为“届时”用于将来时。50. D 本题不应见到具体时刻便选A。应考虑到后面的过去完成时。51B in+ 时间段用于将来时。 .D 选项应为 three days later 。52.A after+ 时间段用于过去时，若在将来时中应带具体时间点。53.B54.A 试比较这两题，虽问句相同但侧重点不同故答案不同。55.B sth begin 的持续性对应词为 sth has(had) been on 。56.B 我到时他已去睡觉了而不是去睡过觉。故选B。57.C 本题用现在完成时询问是否完成某事，经肯定后再用一般过去时说何时完成的。5
