—It’sabox.这是什么?
一只箱子。
(2)作非人称代词表示天气、日期、时间、温度、距离、价值、路程、度量、自然现象与环境等。
也可模糊地指一般情形或上文的部分或整个意思。
译成汉语时,it通常不一定译出来。
It’salongtimesincetheyleft.他们走后很久了。
It’stwomilestothebeach.离海滨有两英里远。
That’sjustit—Ican’tworkwhenyou’remakingsomuchnoise.原因就在这里——你弄出这么大的声音,我工作不了。
另外,需要注意两点:
(1)“It’stime…”后面可以接不定式和介词短语表示“是做……的时候了”。
如:
It’stimeforsupper.It’stimetohavesupper.
(2)“It’stime…”后面还可以接一个从句,但是从句中的谓语动词一定要用过去式即虚拟语气,如:
It’stimewehadlunch.是我们吃饭的时候了。
It’stimewestarted.是我们该出发的时候了。
2.it用作引导词
(1)作形式主语由动词不定式、动词-ing短语或名词性从句担任主语的句子,常用it来作形式主语,而把真正的主语放在句子的后面。
It’snoteasyforustolearnEnglishwell.[句型为:
It+be+形容词+(forsb.)todosth.]
It’sfoolishofyoutosaythattoher.[句型为:
It+be+形容词+(ofsb.)+todosth.]
It’snouse/good/help…sleepingtoomuch.(句型为:
It+be+名词+doing)
It’simportantthatwebethereontime.(句型为:
It+be+形容词+that从句)
It’shightimethatTomwenttoschool.(句型为:
It+be+time+that从句,从句中的动词用过去时)
Itwasthesecondtimethathehadtelephonedmethatday.[句型为:
It+be+thefirst(second,third)time+that从句](that从句中动词用完成时)
Itwasarrangedthattheyshouldleavethefollowingwinter.(句型为:
It+be+过去分词+that从句)
Itappearsthatthetwoleadersareholdingsecrettalks.(句型为:
It+不及物动词+that从句)
(2)作形式宾语当宾语是动词不定式、动词-ing短语或名词性从句时,而宾语后又有宾语补足语,则需用it作形式宾语,将真正的宾语放到宾语补足语的后面。
用于这种结构的动词有:
feel,find,think,make,consider,take等。
MarxfounditimportanttostudythesituationinRussia.马克思发现研究俄国的形势很重要。
Ifinditstrangethatshedoesn’twanttotravel.她竟不想旅游,我觉得很奇怪。
I’llmakeitcleartoyouthatfailureisthemotherofsuccess.我要告诉你们失败是成功之母。
3.it用在强调句型中
英语中,为了突出句子中的某一成分,达到强调或使人特别注意该成分的目的,人们常用“Itis/was+强调对象+who/whom/that….”句式把整个句子分割成前后两个部分,使之各自有自己的谓语动词,中间由that或who/whom连起来成为一个新句子。
除强调人时用who,whom外,其余情况都用连词that。
被强调的对象仅限于句子的主语、宾语、宾语补足语和部分状语(包括状语从句),即除谓语和定语以外的句子成分。
这部分状语主要包括地点状语、由before,when,after,notuntil等引起的时间状语从句、由because,becauseof引起的原因状语、由by引起的方式状语等。
当被强调的对象是人时,可用who,whom或that,其余情况一律用that;
当被强调对象在从句中做主语时用who/that,当被强调对象在从句中做宾语时用whom/that。
原句:
Myfatherdidtheexperimentinthelabyesterdayevening.昨天晚上我父亲在实验室做实验。
Itwasmyfatherdidtheexperimentinthelabyesterdayevening.昨天晚上是我父亲在实验室做实验。
(强调主语)
Itwastheexperimentthatmyfatherdidinthelabyesterdayevening.昨天晚上我父亲在实验室里做的是实验。
(强调宾语)
Itwasyesterdayeveningthatmyfatherdidtheexperimentinthelab.我父亲是昨天晚上在实验室做实验的。
(强调时间状语)
Itwasinthelabthatmyfatherdidtheexperimentyesterdayevening.我父亲昨天晚上是在实验室里做这个实验的。
(强调地点状语)
另外,再注意两点:
(1)强调句如果还原成陈述句的话,句子成分是完整的,如果不完整,那必然是别的从句而不是强调句。
Itwasthetownwherewelivedforthreeyears.此句是定语从句,因为还原以后的句子为:
Welivedthetownforthreeyears.缺少介词(inthetown),而Itwasinthetownthatwelivedforthreeyears.这就是一个强调句了。
(2)强调中心也可以是疑问词,这时要将疑问词置于句首,构成一个特殊疑问句。
Whyisitthatyouwanttoleavesosoon?
你到底为何这么早就要走?
