强调句型讲解与练习

五、考查强调结构与“It be…before…”、“It be…since…”、“It be…when…”等句型的区别(1)掌握强调句型的关键在于把握强调句型的判断标准，即去掉强调句式结构（it is/ was…who/ that…），经过语序相应调整后，原句语法结构和句意仍然正确。

这也是强调句型与定语从句及其它句式的重要区别之一。

例如：① It was because he was ill that he did not come to see you.(去掉强调句型的句式结构“It was…that…”后，原句仍然成立。

)（2）“It +be +some time +before…”此句型关键在于：①主句为将来时态，before从句为一般现在时态；主句为一般过去时态，before从句通常也为一般过去时态。

②主句肯定结构意义为“时间过多久从句中动作才发生”；否定结构意义为“不久，从句中动作就发生”。

例如：① It will be more than 100 years before the country begins once again to look as it did before.要过100多年后这个国家才能恢复到以前的样子。

② It was not long before he worked out the problem.没过多久，他便解出了这道题。

（3）“It +be +some time +since…”这个句型表示“自……开始（结束）以来，已经过去多长时间”。

该句型关键要掌握两点：①主句为“It is(has been)+时段”时，since从句通常用一般过去时；主句为“It was(had been)+时段”时，since从句一般为过去完成时。

②当since从句中的谓语动词是延续性动词或表示状态的动词时，则从句所表示的时间是从那个动作或状态结束时算起，即表明这一动作或状态终止有多久了。

例如：①----What was the party like?----Wonderful. It is years since I enjoyed myself so much.(MET1993)(“晚会怎么样？”“很精彩，我已有多年没有那么高兴过了。

”)② Three years has passed since I smoked.(我戒烟已经三年了。

)③ It is four days since he was ill.(他已经康复四天了。

)（4）“It +be+时间点+when…”掌握此句型的关键在于：“be”后面是个时间“点”，不是时间“段”，句型意义为“当……时，时间是……”例如：① It was five o’clock in the afternoon when they climbed up to the top of the mountain.(他们爬上山顶时是下午五点钟。

)② It was 1919 when the May 4th Movement took place.（“五·四”运动爆发是1919年。

）六、考查强调结构与定语从句的区别判断句子结构是否是强调句型可用还原法，即去掉“it is/ was…that…”,再将被强调部分放在句中相应的位置。

不需要添加任何词语句子正确，即为强调句型结构。

否则就是定语从句。

例如：It was October when they finally came back to their hometown.(when引导一个定语从句，修饰先行词October.)It was in October that they finally came back to their hometown.(此句为强调结构，强调句子的时间状语in October,去掉It was …that …,句意和语法结构完全正确)It was the house where I met the young man.(此句中when引导的是定语从句，修饰先行词the house,在定语从句中作地点状语)It was in the house that I met the young man.(此句为强调结构，强调句中的地点状语in the house) 七、考查强调句型中的结构变化(以一般疑问句、特殊疑问句、名词性从句等形式考查)（1）以一般疑问句的形式考查① Was ____ that I saw last night at the concert?A. it youB. not youC. youD. that yourself比较下句：It was you that I saw last night at the concert.我们可以看出该题干实际上是这个陈述句的一般疑问句形式。

答案应为A。

（2）以特殊疑问句的形式考查② ___ is it ___ has made Peter ____ he is today?A. What; that; thatB. That; that; whatC. What; what; thatD. What; that; what本题结构复杂，请看解析：It is perseverance that has made Peter what he is today.对划线部分提问则可得到：What is it that has made Peter what he is today? 显然此题的答案应为D。

（3）以名词性从句的形式考查③ I’ve already forgotten ____ you put the dictionary.A. that it was thereB. where was it thatC. that where it wasD. where it was that本题是经过变形的强调句型用作宾语从句的体现。

为了更好的理解，我们可以理解为：第一步：复原 It was on the desk that I put the dictionary.第二步：对划线部分提问 Where was it that you put the dictionary?第三步：变为陈述句，将其用作宾语从句，即为该题。

经对比可知答案为D。

(4)与定语从句结合考查④ It was in the lab ____ was taken charge of by Professor Harris ____ they did the experiment.A. which; thatB. that; whatC. whom; thatD. which; where解析：the lab后跟that或which引导的定语从句，而全句应为强调结构。

所以答案为A。

八、考查对强调句型的熟练掌握程度和灵活运用能力。

做题时要认真审题，避免思维定势的影响。

例：① ---- He was nearly killed by a car once.---- Oh, when was that exactly?---- It was in 2004 ____ he was riding a bike on the driving-way.A. thatB. whenC. whereD. in which解析：答案为B。

如果仔细分析一下此句则可看出he was riding a bike on the driving-way应是定语从句，修饰“2004”，表示“当时他正在机动车行道上骑车”，只有这样才能回答上文的提问“when”。

如果要把强调句加上则是“It was in 2004 when he was riding a bike on the driving-way that he was nearly killed by a car once.”。

例：① ---- Was it under the tree ___ you were away talking to a friend?---- Sure. But when I get back there, the bike was gone.A. thatB. whereC. whichD. while解析：答案为D。

做此题时很容易受思维定势的影响，再加之先入为主，这样就会错选A。

如果冷静思考，认真审题就可看出it是一个人称代词，而不是引导词it,指代the bike。

整个句子的意思是“当你走开和朋友谈话时自行车是不是在树下放着？”，故应选D。
