is three years since his father passed away.,It+be+,时间,+before-clause,这个句型中的时间一般为表示一段时间的词语,(,如：,a,long time,months,weeks,days,hours,minutes),，主句中的谓语动词用肯定式，意为,“,过多长时间才,.,”,。主句的谓语动词是否定式时，意为,“,没过多长时间就,.,”,。主句的时态可用过去时,was,或将来时,will be,；用,was,时，,before,从句的动词用一般过去时；用,will be,时，,before,从句常用一般现在时。,她没过多久就背会了那些诗歌。,It was _she learned those poems by heart.,过了很久警察才来。,It was _the police arrived.,要过好几个小时他才会作出决定。,It _hours before he makes a decision.,要不了几个小时我们还会再见面的。,_before

be,，,when,从句用一般现在时代替将来时。,It was already 8 oclock when we got home.,It was the next morning when we finished our work.,It will be midnight when they get there.,It+be+,时间,+that-clause,这个句型是个强调句型。例如：,It was two years ago that he made an,important invention.,(,原句是：,_),It was at 5 o,clock that he practised playing the violin in the morning.,(,原句是：,_),比较：,It was 5 oclock when he started in the morning.,(5 oclock,前没有介词，这是个定语从句,),He made an important invention,two years ago.,He practised playing the violin at 5 oclock in the morning.,It+be+time+that-clause,这个句型属虚拟语气结构，不管主句中用的是,is,或,was,，,that,从句都须用动词的过去式或,should+,动词原型,(,但不及用过去式普通,),，在,time,之前有时可加上,high,或,about,以加强语气,。例如：,It is time(that)we handed in our exercises.,(=It is time that we should hand in our,exercises.),It is high time (that)she wrote a letter to her boyfriend.,It/This/That+the first(second,third)time+that-clause,这个句型表示截止到说话时为止的某人的一种经历，关键是注意,time,前有序数词，主句是,is,时，从句要用现在完成时；如果主句用一般过去时,was,，则从句须相应地用过去完成时。,例如：,This is the first time(that)these Europeans _the Great Wall.,It was the fifth time(that)I _a friendly visit to Africa.,had paid,have visited,There,起始的句型归纳：,1,）,there live/stand/lie/exist,There lay a ditch two metres wide ahead.,2)There come/go/appear/occur/follow,用于描述某事的发生或某个动作的开始。,Eg:There will follow a break of 10 minutes and then we will go on with the lecture.,3)There being,（独立主格结构）,Eg:There being nothing left in the fridge,we had to do some shopping first.,4)there to be,结构常见于动词,intend,mean,consider,hate,want,等词后。,Eg:No one would expect there to be a war in his country.,I dont want there to be another accident like this.,结构：,It+,动词,be+,强调部分,+who(whom)/that+,其他部分,it,可以用来对句子的某一成分加以强调。,It,用于强调句,Eg:Nancy saw your sister in Tokyo last week.,It was,Nancy,who saw your sister in Tokyo last week.,It was,your sister,whom Nancy saw in Tokyo last week.,It was,in Tokyo,that Nancy saw your sister last week.,It was,last week,that Nancy saw your sister in Tokyo.,有些否定句也可以改成这种强调结构：,It wasnt until last summer that I heard from
