1、巧用英语时态表,掌握英语谓语形式一、英语时态名称的记忆时态过去现在将来过去将来一般一般过去时一般现在时一般将来时一般过去将来时进行过去进行时现在进行时将来进行时(略)完成过去完成时现在完成时将来完成时(略)二、英语时态形式的记忆:(以动词work 为例)时态过去现在将来过去将来一般worked work works shall/will work should/would work 进行was/were working am/is/are working shall/will be working(略)完成had worked have/has worked shall/will have w
2、orked(略)可以分两个步骤记忆:1、一般现在时:work(当主语是第三人称单数时,谓语动词也要用第三人称单数形式。)现在进行时:be+working(be 随主语人称和数的变化而变化。)现在完成时:have+worked(have 随主语人称和数的变化而变化,worked 是 work 的过去分词。)这三种基本时态形式位于时态表的中心位置,是必须首先记住的。其它形式可推导而出。2、记住了上面三种时态的形式后,可以设想把时间提前至过去,这三种时态的形式就相应地左移一格成为一般过去时:worked(worked 是 work 的过去式);过去进行时was/were+working;过去完成时h
3、ad+worked(worked 是 work 的过去分词)。把时间错后至将来,这三种时态的形式也就相应地右移一格成为一般将来时:shall/will+work;将来进行时:shall/will+be working;将来完成时:shall/will+have worked。(shall仅用于主语是第一人称时,will可用于主语是任何人称时。)当然,根据shall/will 的用法要求,紧随其后的动词或助动词要用原形形式。简而言之,把这三种现在时态形式左移变成三种过去时态形式,只需把第一个动词变成过去式即可(一般现在时谓语只有一个动词,也可把它看成为第一个动词)。与此类似,过去将来时的变化是在
4、一般将来时的基础上把第一个动词变成过去式。把这三种现在时态形式右移变成三种将来时态形式,只需在前面加一助动词 shall/will(紧随其后的动词或助动词用原形形式)即可。三、英语被动语态形式的记忆(以动词ask 为例)时态过去现在将来过去将来一般was/were asked am/is/are asked shall/will be asked should/would be asked 进行was/were being asked am/is/are being asked 完成had been asked have/has been asked 英语动词的被动语态是由助动词be 加及物动
5、词的过去分词构成。助动词 be 同系动词be 一样有人称、数和时态的变化。英语动词在既有被动语态变化又有时态变化时,一定要先变被动语态再变时态,它的时态变化就是将助动词be 再作各种时态形式的变化。主张先理解记忆现在的三种被动语态的时态形式,再以同样方法推导出被动语态其它的时态形式。四、结合英语时态表掌握句子的否定式、一般疑问式的变化规律句子的否定式、一般疑问式也是每册初中教材学习时态时的必讲内容。而实际上这个问题非常简单,完全可以结合英语时态表中谓语的特征来完成。变化方面谓语物征否定句变化一般疑问句变化谓语只有一个动词(be除外)根据主语人称、数和谓语时态的要求,在谓语动词前加dont,do
6、esnt,didnt 后面的动词使用原形。根据主语人称、数和谓语时态的要求,在句首加Do,Does,Did,其后面的动词使用原形。更改句首大小写和句尾标点符号。谓语有两个或两个以上动词在谓语的第一个动词后面加not.把谓语的第一个动词提前至句首,更改首大、小写和句尾标点符号。注:1、There be.句型和以 be 为系动词的主系表句型,适用于第二种谓语特征的变化方式。2、谓语是情态动词(have to的疑问式例外)+动词原形,也适用于第二种谓语特征的变化方式。3、为便于记忆,不妨称此法为谓语特征分析法。五、谓语特征分析法在特殊疑问句、反意疑问句中的运用由于特殊疑问句的句子结构是特殊疑问词或词
7、组+一般疑问句语序,故除对主语提问的特殊疑问句外,都可按一般疑问句变化规律用谓语特征分析法快速确定谓语形式。反意疑问句是由陈述句+反问部分构成。反意疑问句的反问部分虽说情况比较复杂,但仅就基础内容而言,情况还是较为简单,要求也较低。故基础内容中反意疑问句的反问部分基本上仍可用谓语特征分析法快速确定反问部分中该用的动词,那就是:前面的陈述句如果变成一般疑问句是用什么动词开头,后面的反问部分就用什么动词反问。六、一般疑问句和反意疑问句的简略回答用谓语特征分析法掌握了一般疑问句和反意疑问句中谓语的构成方法后,它们的简略回答就更容易了。那就是用什么词开头的一般疑问句就用什么词来回答(或同属be 系列的
8、单词:am,is,are,was,were)。反意疑问句的反问部分用什么词开头,也就用什么词来回答(或同属be 系列的单词)。例如:1.-Are you a worker?-Yes,I am./No,Im not.2.-Does he like Chinese tea?-Yes,he does./No,he doesnt.3.-Have you finished the novel?-Yes,I have./No,I havent.4.-He is a bus driver,isnt he?-Yes,he is./No,he isnt.5.-Tom came to school late th
9、is morning,didnt he?-Yes,he did./No,he didnt.6.-Lily hasnt lost her watch,has she?-Yes,she has./No,she hasnt.用情态动词(can,may,must)开头的一般疑问句,在作否定回答时选择合适的情态动词较为困难。我们可以用右栏图示轻松地记忆掌握。先按下列单词及它们的否定式的第一、第二个字母在字母表中的顺序排列,再加上谁回答谁的替换符号便容易记忆了。(注意must 代替 may,need 代替 must,这种后代前的关系以及can 除了可回答自己外,还可回过去来回答may的特点。)文档编码:C
