   初中英语it 的用法知识点(一)


  代词it,在初中英语中几乎处处都有它的位置。可见,it虽小用处很大。现将其用法归纳如下:
  1.用来代替前面提到过的人或事。
  What’sthis?It’sabus.
  2.指人时可作为指示代词看待,一般不必译出。
  Whoisknockingatthedoor?It’sme.
  Whoisit?It’sme.
  3.指天气状况等。
  Itisgoingtorain.It’srathercoldnow.
  It’sverycoldtoday.
  4.指时间。
  It’sSundayagain.
  It’seighto’clockinthemorning.
  It’sfiveyearssinceIsawyoulast.
  5.指距离。
  It’sonlyfiveminutes’walknow.
  Itis6milestothemuseum.
  Isitveryfartothecableoffice?
  6.指环境状况等。
  Itwasverynoisyatthemoment.
  7.泛指一般情形,或依上下文可以领会的事物,有的属于习惯用法,无法确定其含义。
  That’sit!对啦!Soitseems.好像是这样。
  That’sthebestofit!那最好了!Keepatit!继续干!
  8.用来代替小孩和婴儿。
  Thechildsmiledwhenitsawitsmother.
  9.代替整个句子。
  Youhavesavedmylife.Ishallneverforgetit.
  10.作形式主语,使句子不至于“头重脚轻”。
  It’sgoodtoseeallmyteachersandfriendsagain.
  It’sinterestingtoclimbhills.
  It’sapitythatyoudidn’tgotoseethefilm.
  11.也可以作形式宾语。
  Shefounditverydifficulttoanswerthequestion.
  初中英语it 的用法知识点(二)
  (2011天津.1)We feel _____our duty to make our country a better place。
  A.it B.this C.that D.one 选A
  (2011江西.25)Why don’t you bring ____ to his attention that you are too ill to work on?
  A.that B.it C.this D.him 选B
  (2007天津.1) 1.He didn’t make____clear when and where the meeting would be held。
  A.his B.that C.it D.these 选C
  (2009四川.3)I like this house with a beautiful garden in front, but I don’t have enough money to buy ______。
  A.one B.it C.this D.that 选B
  规律:当三个代词it,this,that同时出现在单项选择题中时,大多数情况下选择it。
  个别情况可能为that或the one,如:(2010陕西.12)The cost of renting a house in central Xi’an is higher than____in any other area of the city。
  A.that B.this C.it D.one 选A
  分析:该题中that指代前面的the cost,因为前后两个cost分指两个地方的,所以不是同一物,故不能选it,但这种题在高考中出现较少,因为该知识点属于初中范畴。
  虽然存在上面这种特殊情况,但是因为it适用范围广泛,按照大概率原理,前面的规律依然成立。现在我们归纳一下去年天津高考中有关it的考查:
  it作普通指示代词,可以指天气、时间等,也可以指代前面提到过的具体事物或事件。
  如:2011天津阅读理解A篇 You have no right to entertain 1 friends in a family home as some families feel it is an invasion 2 of their privacy 3。(it指“在房东家里款待朋友”这件事)
  it作形式主、宾语,如: (2011天津.5)Although regular exercise is very important, it’s never a good idea to exercise too close to bedtime 4。(it作形式主语)而在上面2011天津.1和 2007天津.1两题中,it均作形式宾语。
  it用于强调句型“It is/ was +被强调的部分+ that/who + 句子剩余部分”,如:2011天津完型填空It was years later that I finally understood what role modeling played in your life。(强调时间状语years later)
  it在固定句式中,如:2011天津阅读理解B篇 It always struck me that when you’re looking at a big challenge 5 from the outside it looks huge, but when you’re in the midst 6 of it, it just seems normal. (It struck sb that…是英语中一个很有用的句式,其意为“某人突然感到(觉得)……”,后三个it均指代challenge。)
  由此不难看出,对it的考查遍及高考英语所有题型,甚至写作中同学们也可以借助它写一些能给作文提分的句子,例如:
  It is no good (use) doing sth. “做……没用”
  It is no wonder that“难怪……;……也不足为奇”
  It takes sb +时间、金钱+to do sth. “做……要花费某人时间或金钱”
  It is likely that… “很有可能会……”
  It +is +(high) time that 从句 “该干某事了”
  在一结构中从句须用should +动词原形(should 不能省略)或动词过去式
  It is +形容词+of/for sb to do sth。
  该句型中的不定式短语是真正主语,如果不定式的逻辑主语是由of引出,主句中的形容词必须是描述人的形容词。常见的有: careless, cruel, lazy, modest等;如果不定式的逻辑主语是由for 引出的,主句的形容词通常是描述事情的形容词,如:important,necessary,natural,easy等。
  It is + 时间 + 连词 (that,since,before,when)方法:第一步,优先假定选that,则该句子为强调句,去掉it is 和 that 看剩下的句子是否在意思和语法上均完整。如果完整,则假定成立;反之,不选that。第二步,若为时间点,则选when,如half past two;若为时间段,则考虑since和before。其中before翻译成“才,就”,since译为“自从”。
