2012届高考英语一轮复习代词语法课件;一、it 的用法 1.作人称代词 John likes playing Pingpong./ He always does it in the afternoon.(指代上下文提到的事物)/Its time we went home. / How far is it from here to your home ? / It is getting warmer and warmer./ Its very quiet at the moment.(可指时间、天气、环境等) 2.作形式主语,代替由不定式、动名词或从句表示的真正主语。 Its important for us to learn a second language./ Its no use talking to him./ Its known to all that the earth goes round the sun. 3.作形式宾语,代替由不定式、动名词或从句表示的真正宾语。 We feel it our duty to help others./ He made it clear that he would leave the city. 4.强调结构:It is (was) +被强调部分+that (或who)... ;注意: 在强调结构中,如被强调部分为时间状语或地点状语,其后的连接词也绝不能为when 或where,而应用that 。在复习中,一定要注意句式的不同。 It was in Shanghai that I bought the guitar.(that引起强调句) It was Shanghai where I bought the guitar.(where引起定语从句) It was twelve oclock when we arrived there.(when引起时间状语从句) It was at twelve oclock that we arrived there.(that 引起强调句);二、it,one,that 的区别 1. it指代上文所提事物的本身(it表时间、强调等的用法此处不阐明),如果所代替的事物为复数,则应该用they或them表示。it也可以用来代替上文所提到的一件事。 2. that用来指前文中确定的非同一事物,常用来替代与定冠词或形容词性物主代词连用的单数可数名词或不可数名词,相当于“the+名词”,其复数形式为those。that表替代时始终是特指(作指示代词和关系代词用时另论),可指上文谈到的人、物或情况(均为单数),可代替可数名词和不可数名词。;3.one常用来代替与上文所提到人或物相类似的不确定的另一人或物(泛指),且被替代者为可数名词单数形式。若下文替代者表示非特指含义,则用a/an-adj-one形式表示;若下文替代者为另一特指含义,则用the one或the-adj-one表示;若下文替代时为复数含义,则用the-adj-ones 或the ones表示。 (1)one作替代词用时,其前可加某些形容词或限定词,如the,this,that,which,each,every,any等,但一般不能直接在其前??物主代词。 (2)one被后置定语修饰表示特指时,前面应加the;被形容词修饰表示泛指时,其前应加a/an;被形容词修饰表示特指时其前应加the。 (3)one作主语时,其对应的物主代词用ones或his,反身代词用oneself或himself,重复主语用one 或he。;三、不定代词 不定代词有both, either, neither, one, the other, another, little, few, some, any, each, every, no, none等,从实际应用和理解出发,重点学习以下几个:;1.both/either/neither (1)both为“两者都”,neither为“两者都不”,either为“两者之一”。这三个单词都用于指两个人或物,在句中可作主语、宾语和定语。 ①作主语: Both (of them) enjoyed the rice. 他们两人都喜欢吃米饭。 Neither (of us) is a doctor. 我们俩都不是医生。 Either (of you) will go. 随你们哪个去都可以。 注意:作主语时,both后面的谓语动词用复数。neither, either后面的谓语动词一般用单数形式。 ②作定语: Both Zhang Huas father and mother work in a hospital, but neither one is a doctor
