18、o.It was Leo who/that began to teach us English two years ago.(强调主语)It was English that Leo began to teach us two years ago.(强调宾语)It was two years ago that Leo began to teach us English.(强调时间状语)注意:(1)强调句子的主语句子的主语结构设置复杂,有接不定式作定语的,有接定语从句作定语的,还有使用主语从句、并列结构或同位语结构的,这些会干扰学生的解题思路,但只要抓住了句子的主干,问题也就迎刃而解了。如:It

19、 was what he did that made his parents upset.It is the ability to do the job not where you come from or what you are that matters.It is not where someone comes from and what a person looks like that is important but what he grows up to be.说明:强调某人时,可以用who代替that,that(who)后面的谓语动词要和被强调部分的主语部分在语法上保持一致。如:

20、It is I who am responsible for this case.(2)强调句子中的时间、地点、方式等状语这些状语可以是状语从句,介词短语或介词短语中的名词后再接定语从句等。如:It was because it was raining hard that I was late for school.It was not until I arrived there that I began to know something about the matter.It was in the very house that was built with stones that he

21、spent his childhooD(3)强调句的一般疑问句式和特殊疑问句式一般疑问句式:Is/Wasit被强调部分that/who其他成分?如:Was it Leo that/who began to teach you English two years ago?Is it in your school that the famous professor will make a speech?特殊疑问句式:特殊疑问词is/wasitthat其他成分?Who was it that began to teach you English two years ago?What subject

24、came back.强调句式:It was not until his mother came back that the little boy went to bed说明:此句型只能使用until,不能用till。如果不使用强调句式,till与until一般可通用;因为“It is/was not.”已经是否定句了,that后面的部分要用肯定句,切勿再用否定句。3it引起的关于时间的容易混淆的句型(1)Itis/has been/was一段时间since从句该句型常译为“自从以来已经一段时间了”。若since引导的从句使用一般过去时,主句中的时态要使用一般现在时或现在完成时;如果从句使用过去

25、完成时态,主句中则使用一般过去时(was);此时,从句中的谓语动词要使用非延续性动词。如:It is many years since he left his hometown.他离开家乡许多年了。It has been three years since I began to stay in Beijing.我在北京已经待了三年了。比较:It has been three years since I stayed in Beijing.我离开北京已经三年了。(2)Itwas/will be一段时间before从句该句型中的时间常为long,a long time,years,months,w

26、eeks,days,hours,minutes等时间段。如果主句中的谓语动词使用肯定式,常译为“过了一段时间才/要过一段时间才能”;若使用否定式,常译为“没过一段时间就/用不了一段时间就会”或“不久就/不久就会”。主句的时态可以使用过去时was或将来时will be,用is时,before从句常使用一般现在时表示将来。如:It was long before the police arrived过了很久警察才来。It was not long before she learned those poems by heart.没过多久她就记住了那些诗歌。It will be three days

27、before he makes a decision.要过三天他才能作出决定。It will not be hours before we meet again.要不了几个小时我们就会再见面的。(3)Itis/wastimethat从句该句型常译为“(正)是的时候了”,可与Its time for sBto do sth.进行转换,属于虚拟语气结构。不管主句中使用is还是was(多用is),that从句都必须使用动词的过去式或“should动词原形”,time前可用about或high修饰,以加强语气。如:It is time (that) we handed in our exercises

28、.It is high time that we should get started(4)Itis/wasthe first/second/.timethat从句该句型常译为“这是第一次/第二次/做”。主句中的it可以替换为this或that。如果主句使用一般现在时is,从句要使用现在完成时;如果主句使用一般过去时was,从句则使用过去完成时。如:This is the first time (that) these Europeans have visited the Great Wall.1(2015真题改编重庆) Bach died in 1750, but it was not un

29、til the early 19th century _ his musical gift was fully recognizeD答案:that句意:马赫死于1750年,但直到19世纪他的音乐天赋才被承认。强调句与not until连用。It be not until that.故填that。2(2015真题改编重庆) It was when we were returning home _ I realized what a good feeling it was to have helped someone in trouble.答案:that考查强调句。3(真题改编天津)It was

30、not until near the end of the letter _ she mentioned her own plan.答案:that本题考查强调句。句意:直到接近信的末尾她才提到了她自己的计划。It is/was not until thatclause是not until的强调句句式,故填that。4(真题改编重庆)It was with the help of the local guide _ the mountain climber was rescued答案:that本题考查强调句。句意:是在当地导游的帮助下登山者被救的。分析结构可知,此处是强调句,强调的是句子的状语w

31、ith the help of the local guide;由强调句的基本句子结构“It is/was被强调部分that(强调人可以用who)其他”可知应填that。判断正误,改正错句1Why!
