怎么考 在语境中考查各种时态与语态形式。 怎么学 在平时的阅读、写作训练中，认真体会动词的各种时态、语态形式，不拘泥于语法。 怎么解 1.通过“时态定义”解题；2.通过“固定结构”解题；3.通过“语境暗示”解题。,.体验考向 用所给动词的适当形式填空。 1.(2015江苏卷)The real reason why prices _(be)，and still are，too high is complex，and no short discussion can satisfactorily explain this problem. 2.(2015湖南卷)As you go through this book，you _(find)that each of the millions of people who lived through World War had a different experience. 3.(2015北京卷)Dr.Jackson is not in his office at the moment.

No，he _(change)his mind after a phone call at the last minute. 6.(2015陕西卷)At college，Barack Obama didnt know that he _(become)the first black president of the United States of America. 7.(2015四川卷)More expressways_(build)in Sichuan soon to promote the local economy.,答案 1.were句意：价格过去和现在仍然过高的原因是复杂的，没有简短的讨论可以令人满意地解释这个问题。根据and still are可以推断出空白处是对过去时态的考查。 2.will find句意：在你浏览这本书时，你会发现经历二战的数百万人的经历各不相同。as引导时间状语从句，意思是“当的时候”，在从句中使用的是一般现在时，所以主句使用一般将来时，即所谓“主将从现”，主句使用一般将来时，从句使用一般现在时。,3.will call句意：Dr.Jackson现在不在他的办公室里。好的，过一会儿我再给他打电话。由句中的later可知此处要用一般将来时。 4.was going to句意：爱因斯坦出生于1879年。小时候，几乎没有人想到他会成为一个其理论将会改变世界的科学家。根据语境可知，此处要用过去将来时。 5.changed句意：彼特要来吗？不，当接到一个电话后，他最后时刻改变了主意。句中的after a phone call at the last minute 表明动作发生在过去，故用一般过去时。,6.was to become/would become句意：大学的时候，奥巴马不知道他会成为美国的第一位黑人总统。表示“注定成为”要用be to do；主句是一般过去时，所以从句要用过去将来时。 7.will be built句意：四川将建设更多的高速公路以促进当地的经济(发展)。根据时间状语soon可知，此空为将来时；主语expressways和动词build之间为动宾关系，故要用一般将来时的被动形式。,.语境感悟 用所给词的适当形式完成下列短文，然后朗读或背诵，体会动词时态、语态的用法。 When he was a little boy，Christopher Cockerell once watched his mother turning the wheel of her sewing-machine with her hand. “Wouldnt it work quickly if the machine _1_ (turn) the wheel for you？”he asked. “I suppose it would，”said his mother，without paying any attention to him.,Christopher _2_ (know) she always had a lot of work，and he wanted to help.In his bedroom there was a toy steam-engine which his father _3_ (buy) him as a gift.“I _4_ (make) better use of it，”little Christopher said to himself.So，when his mother _5_ (not use) her sewing-machine，he fixed the toy steam-engine onto it.When the job _6_ (finish)，he was quite pleased，thinking his mother _7_ (like) it.,“Very clever，”his mother said，when she saw it.Then she sat down and went on turning the wheel by hand.“I _8_ (work) like this for too many years，” she explained. This taught Christopher the lesson that anyone who _9_ (try) to improve anything _10_ (have) to learn：Many people dont like new ideas.,答案 1.turned表示对现在的虚拟，用一般过去时。 2.knew一般过去时表示过去的动作。 3.had bought表示“过去的过去”用过去完成时。 4.will/shall make此处用一般将来时表示临时的决定或安排。 5.was not using过去进行时表示过去某一时刻或某一段时间内正在进行的动作。,6.was finished一般过去时的被动语态。 7.would like过去将来时，相对于过去某一时刻而言即将发生的动作或存在的状态。 8.have been working用来表示从过去某一时刻开始一直持续到现在(还要继续下去)的动作。 9.tries一般现在时表示经常发生的、习惯性的动作、客观真理、科学事实等。 10.has同上题。,.正反探究 1.【误】Hi，Lucy，you look tired.Im really tired.I have painted the living room all day. 【正】Hi，Lucy，you look tired.Im really tired.I have been painting the living room all day. 解析现在完成进行时态，表示过去发生的动作持续到现在并有可能会继续下去。这一点是从时间状语 all day (整天)看出来的。,2.【误】Nancy is not coming tonight.But she has promised! 【正】Nancy is not coming tonight.But she promised! 解析南希“答应要来”这个动作应该发生在过去，是过去作出的承诺，前文已告诉我们“她不来了”，因此诺言已跟现在没有关系，只是过去的一个动作。,3.【误】 When Tony phoned me I had just finished my work and started to take a shower. 【正】 When Tony phoned me I had just finished my work and was starting to take a shower. 解析从关键信息 I had just finished my work 可以看出是“正要开始洗澡”应该是将来时，was starting 可以表示马上就要进行的动作；而 started 表示“开始了”。,4.【误】 I dont really work here；I just help out until the new secretary arrives. 【正】 I dont really work here；I am just helping out until the new secretary arrives. 解析一般现在时表示现在的、经常性的行为或状态，而现在进行时表示正在进行的、暂时性的动作。本句是用现在进行时的形式表示将来时，此处表示“我”现在只是在临时帮忙，是现阶段正在进行的动作。,5.很多的鸟类正被人们捕杀。 【误】 Many birds are killed now. 【正】 Many birds are being killed now. 解析现在进行时的被动语态结构要完整，不能遗漏其中的助动词，导致时态错误。,.考点确认 一、常考各种时态的用法 1.一般现在时 (1)表示经常发生的、习惯性的动作，通常用usually，often，always，sometimes，every day，once a week等作时间状语。 I usually have my hair cut once a month.
