初中英语知识点:语。
法时态。各位读友大家好,此文档由网络收集而来,欢迎您**,谢谢。
语法:直接引语变间接引语。直接引用别人的话叫直接引语,用来转述别人的话叫间接引语。例:
hesaid,“hewillgotobeijingtomorrow.”
hesaidthathewouldgotobeijingthe next day.
直接引语变间接引语时时态、人称及一些时间或个别词都要做相应的改变。
时态:一般现在时→一般过去时一般将来时→过去将来时。
现在进行时→过去进行时一般过去时→过去完成时。
现在完成时→过去完成时。
但真理性的句子时态不变。例精选公文范文。

直接引语是一般疑问句,变成用if/whether引导的宾语从句,人称时态等作相应改变。
mother asked me,“did you buy anymeat for lunch?”→
motheraskedmeif/whetherihadbought some meat for lunch.
直接引语是特殊问句,变成由原来疑问词一样的连接词引导的宾语从句,时态人称等作相应改变。例:”what do you do?
” he asked asked me what i did.
直接引语是选择问句变成由whether或if引导的宾语从句。
doyoulikeenglishorchinese?”he asked me.
he asked me whether i liked englishor chinese.
语法:被动语态。
1.英语中动词有两种语态:主动语态和被动语态。
主动语态表示主语是谓语动词动作精选公文范文。

的执行者,被动语态表示主语是谓语动词动作的承受者。
当我们强调谁是某个动作的执行者,即”谁做了某种事情”时,用主动语态。
eg: daniel bought a new computer丹尼尔买了一台新电脑。
如果主语不是动作的执行者,而是动作的承受者时,就是被动语态。
eg:anewcomputerwasboughtbydaniel一台新电脑被丹尼尔买了。被动语态的谓语由be+动词的过去分词构成,其中be是助动词,随时态改变。
一般现在时的被动语态由”am/is/are+动词的过去分词”构成。
一般过去时的被动语态由”was/were+动词的过去分词”构成。2.被动语态的用法:
当不知道或没必要说明动作的执行者时,用被动语态。
eg: rice is grown in south china.华精选公文范文。

南种植水稻。
thisbridgewasbuilt100yearsago.这座桥是100年前建的。passivevoice with ‘by’
在被动语态中,如果我们也要把动作的执行者表达出来的话,我们就在被动句子的后面,用“by+动作的执行者”来表示。
jack broke the window.
thewindowwasbrokenbyjack.窗户是被杰克打碎的。
mealsarecookedbyhermotherathome.在家饭是她母亲烧的。
the book was written by him severalyears ago.这本书是他几年前写的。3.难点:
1).当一个含有复合宾语的句子变为被动语态时,只能把宾语变为被动语态的主语,宾补还放在原来的位置。wecallhimxiaowang.
--heiscalled xiao wang.
he cut his hair short.--his hair was精选公文范文。
精选公文范文。
cut short.
2).带双宾语的动词变为被动语态时,常常把间接宾语变为被动语态的主语;如果直接宾语变为被动语态的主语时,间接宾语前要加介词to或for.
someoneg**etheboyanapple.--the boy was given an apple.
an apple was given to the boy.
hismotherboughtapresentforhim.--he was bought a present was bought for him.
3).在let,hear,watch,see,help,h**e等词的句子中,主动语态不加to,被动语态要加to.
the boss makes us work 12 hours aday.--wearemadetowork12hoursaday.
theyheardthechildrensingthatmorning.--thechildrenwereheardtosing that morning.
直接引语是祈使句,根据说话语气变成ask/tell/order warn sb. to do sth.的精选公文范文。
