初中英语-冠词专项练习(精选习题及答案解析)一、初中英语冠词1．—What sport do you like best?—I like playing ________ baseball, and ________ baseball under the desk is mine.A．the; the B．/; the C．the; / D．/; /【答案】B【解析】【详解】句意：——你最喜欢什么运动?——我喜欢打棒球，桌子下面的这个棒球是我的。
考查冠词辨析。
the表示特指。
play后面跟球类时，球类前面不加冠词；结合空后“under the desk”可知，第二个空格后“baseball”表示特指，前面要加定冠词the。
故选B。

不定冠词a/an表示泛指；定冠词the表示特指。
此处考查定冠词the的另一个用法，“the+姓氏复数”表示“……的一家人”，“the Browns”表示“布朗一家人或布朗夫妇”。
故选A。

强调句、It的用法（一）强调句句型1、陈述句的强调句型：It is/ was + 被强调部分（通常是主语、宾语或状语）+ that/ who（当强调主语且主语指人）+ 其它部分。
. It was yesterday that he met Li Ping.2、一般疑问句的强调句型：同上，只是把is/ was提到it前面。
. Was it yesterday that he met Li Ping3、特殊疑问句的强调句型：被强调部分（通常是疑问代词或疑问副词）+ is/ was + it + that/ who + 其它部分. When and where was it that you were born4、强调句例句：针对I met Li Ming at the railway station yesterday.句子进行强调。
强调主语：It was I that (who) met Li Ming at the railway station yesterday.强调宾语：It was Li Ming that I met at the railway station yesterday.强调地点状语：It was at the railway station that I met Li Ming yesterday.强调时间状语：It was yesterday that I met Li Ming at the railway station.5、注意：构成强调句的it本身没有词义；强调句中的连接词一般只用that, who，即使在强调时间状语和地点状语时也如此，that, who不可省略；强调句中的时态只用两种，一般现在时和一般过去时。
原句谓语动词是一般过去时、过去完成时和过去进行时，用It was … ，其余的时态用It is … 。
（二）not … until … 句型的强调句1、句型为：It is/ was not until + 被强调部分 + that + 其它部分. 普通句：He didn’t go to bed until/ till his wife came back.强调句：It was not until his wife came back that he went to bed.2、注意：此句型只用until，不用till。
但如果不是强调句型，till, until可通用；因为句型中It is/ was not … 已经是否定句了，that后面的从句要用肯定句，切勿再用否定句了。
（三）谓语动词的强调1、It is/ was … that … 结构不能强调谓语，如果需要强调谓语时，用助动词do/ does或did。
. Do sit down. 务必请坐。
He did write to you last week. 上周他确实给你写了信。
Do be careful when you cross the street. 过马路时，务必（千万）要小心啊！2、注意：此种强调只用do/ does和did ，没有别的形式；过去时用did ，后面的谓语动词用原形。
It的用法（一）作人称代词1、it代替前面（或后面）的单数名词或分句等所表示的事物。
. You cannot eat your cake but have it.（it代替前面的cake）Although we cannot see it, there is air all around us. （it 代替后面的air）They say he has left town, but I don’t believe it. （it 代替前面They…town分句中的情况）2、代替有生命但不能或不必分阴阳性的东西（包括婴儿）。
. Yesterday we saw a big tree. It was fully twenty metres high. （it代替前面的tree）The baby cried because it was hungry. （it代替前面的baby）3、在某些习惯说法中，可以代替人。
. ---- Someone is knocking at the door, Peter. ---- Who is it ---- It’s me.---- Who are singing ---- It is the children.---- The light is still on in the lab. It must be the third-year students doing the experiment.4、it与one的区别：这两个词都可以代表前面说过的名词，但it用于同名同物的场合；one则用于同名异物的场合。
. ---- Do you still have the bicycle ---- No, I have sold it.---- Is this knife yours ---- No. It is Xiao Zhang’s. Mine is the one on the desk.5、it与that的区别：两词都可代替某一特定名词，但that指同一类，并非同一个。
. The climate of South China is mild（温和的）; I like it very much.（it指the climate of South China）The climate of South China is much better than that of Japan.（that指the climate）（二）作无人称代词it作无人称代词时，除了句中找不到它所代表的词语外，另一个特点是它后面的内容都是表示天气、时间、距离、度量衡及情况等。
It is fine (rainy, windy, etc.). It is noon.It is a half hour’s walk to the factory. It is eighteen square metres in area.What does it matter（三）作强调词，构成强调结构用以帮助改变句子结构，使句子的某一成分受到强调。
“It is (was) + 所强调的成分 + that (who) + 其它成分。
”在这个句型中，it本身没有词义。
详见“一、强调句”。
（四）引导词it作形式主语（宾语）为了使句子平衡，常采用形式主语（或宾语）it ，而把真正的主语（或宾语）置于句子后面。
通常引导词it与它所代替的句子成分中间要夹有某些词。
. It takes half an hour to go there on foot.（It与to go there on foot之间夹有takes half an hour四个词）We thought it strange that Mr Smith did not come last night. （it 与that从句中间夹有 strange）但有时it与所替代部分之间并不夹有其它词。
. You may depend on it that they will support you.（因为介词on之后一般不直接接that引导的宾语从句。
注意：it不是多余的，不能当作错句）习题精选---It用法:1. I like in the autumn when the weather is clear and bright.A. thisB. thatC. itD. one[解析] C.句中like为及物动词,后面需要跟宾语.而like之后不可直接接从句作宾语.it可用于某些动词(hate, appreciate…)和介词之后作笼统宾语.2. He was nearly drowned once. When waswas in 1998 when he was in middle school.A. that; ItB. this; ThisC. this; ItD. that; This [解析]A. 第一空用that指代上文提到的事情; 第二空用it指代第一空的that3. The Parkers bought a new house but will need a lot of work before they can move in.A. they B. it C. one D. which[解析] B此处it指代前面出现的a new house. it指代上文提到的同一事物,为特指;而one通常指代同类事物中的某一个.4.
