代词that、it、one用法讲解练习题
代词that、it、one用法讲解练习题代词that、it、one用法讲解与练习题1.(典型例题) I’m moving to the country because the air there is much fresher than__ in the city.A. onesB. oneC. thatD. those[考场错解] B[专家把脉] 在比较状语从句中，指代前文的可数名词单数形式用that或the one，复数形式用those,而不可数名词则用that.这里比较的是air，所以用that.2.(典型例题)Meeting my uncle after all these years was an unforgettable moment,I will always treasureA.thatB.oneC.itD.what[考场错解] D或A[专家把脉] 误选D的原因是学生容易把what当作定语从句的引导词。
而出at不能引导非限制性定语从句；it在句法上讲不通，因此，可以看出one指代an unforgenable moment，同时其后的关系代词出at省略了。
[对症下药] B3.(典型例题国 ) I like in the autumn when the weather is clearand bright.A. thisB. thatC. itD. one[考场错解] B或D[专家把脉] 本题中like是及物动词，需要宾语。
此处it指模糊的情形或环境，没有具体的指代，是虚词。
其余的选项都是错误的。
再如典型例题套中的一题:—I like __ here?—Oh, yes. The air, the weather, the way of life. Everything is so nice!A. thisB. theseC. itD. that[对症下药] C4.( 经典题) Few pleasures can equal of a cool drink on a hot day.A. someB. anyC. thatD. those[考场错解] D[专家把脉] 如果把它动作是few Pleasures，就会误选 D项了。

如：I happened to meet Tom in the street the day before yesterday.It was Tom that I happened to meet in the street the day before yesterday.It was I who / that happened to meet Tom in the street the day before yesterday. It was in the street that I happened to meet Tom the day before yesterday.It was the day before yesterday that I happened to meet Tom in the street. I. 如果强调的部分是人，则人称代词须保持原来的形式，这时连接词可用who, whom代替that。
如：It is he who / that teaches us French.It is us who / whom / that he teaches French.II. 如果强调句子中的地点、时间或原因状语时，连接词仍用that，不能用where, when或why。
如：It is at the street crossing that I met one of my classmates that I had not seen for ages.It was last month that I took part in the Palace ball.我是在上个月参加的宫廷舞会（不能用when）。

Definitely三、阅读理解Robert Pershing Wadlow was the tallest person in history. Wadlow reached 8.111 feet (2. 720m) in height and weighed 199 kg at his death at age 22. His great size and his continued growth in adulthood was due to hypertrophy of his pituitary gland (脑下垂体肥大), which results in an abnormally high level of human growth hormone. He showed no indication of an end to his growth even at the time of his death.Wadlow was born in Alton, Illinois on February 22, 1918, and was the oldest of five children. During elementary school, they had to make a specialized desk for him due to his size. In 1936, after graduating from Alton High School, he enrolled in Shurtleff College with the intention of studying law.Wadlow’s size began to bring trouble: he required leg braces to walk, and had little feeling in his legs and feet. Despite these difficulties, Wadlow never used a wheelchair.Wadlow was an American celebrity; he was well-known due to his 1936 U. S. tour with the Ringling Brothers Circus and his 1938 promotional tour with the INTERCO. He continued participating in tours and public appearances. His shoes were provided to him free of charge by a shoe company for which he did promotional work and appearances. Examples still exist in several locations throughout the US, including the Alton Museum of History and Art.One year before his death, he passed John Rogan as the tallest person ever.On July 4, 1940, during a professional appearance at the Manistee National Forest Festival, a brace injured his ankle, causing a blister and infection. Doctors treated him with a blood transfusion and emergency surgery, but his condition worsened and on July 15, 1940, he died in his sleep at age 22.More than 30, 000 people attended Wadlow’s funeral on July 19. He was buried in a 10-foot-long(3. 0m), haft-ton coffin(石棺)that required twelve strong men to carry.1. When did Wadlow almost lose his feeling in his legs and feet?A. When he was born in Alton.B. When he was in elementary school.C. After he graduated from Alton High School.D. After he enrolled in Shurtleff College.2. When did Wadlow become the tallest man in the world?A. In 1918.B. In 1936.C. In 1939.D. In 1940.3. Wadlow was a famous person mainly because ________.A. he participated in some tours and public appearancesB. he required leg braces to walk with an amazing heightC. he couldn’t walk normally and had to use a wheelchairD. he continued to grow until he was dying4. According to the text, we can infer that Wadlow ________.A. was very happy with his sizeB. was very strong despite his sizeC. died from his ankle injuryD. keeps the record in size up to now四、句子翻译下面含有it的例句都是来自2015年高试题，试着翻译成中文。
“It”作形式主语和形式宾语的用法详解及习题演练
新希望英语语法精讲------“It”作形式主语和形式宾语“It”作形式主语和形式宾语的用法详解It作形式主语和形式宾语用法，是英语学习的主要语法项目之一。
无论是单项选择，还是完行填空，it 用法始终是反复考查的重、热点之一。
现将it在特殊句型中作形式主语和形式宾语用法，进行如下归纳分析，以供学习参考。
一、It 用作形式主语当不定式（短语）、动名词（短语）或从句在某个句子中作主语时，为保持句子结构前后平衡，避免头重脚轻，因此常用it作形式主语置于句首，而将真正的主语放在句尾。
此时it只起先行引导作用，本身无词义。
e.g. It is wrong to tell a lie. (说谎是错误的。
) 〔It为to tell a lie的形式主语〕It is no use arguing about it. (争吵是没用的。
) 〔It为arguing about it的形式主语〕It is uncertain who will come. (谁要来还不确定。
) 〔It为who will come的形式主语〕It 作形式主语的常见句型：①It + be + 形容词+ to do sth. / doing / that ….e.g. It is very important to learn a foreign language. (学一门外语非常重要。
)It is useless crying over the spilt milk. (覆水难收。
)It was really surprising that she married a man like that.(她嫁给那样的男士真让人惊讶。
)②It + be +名词词组+ doing / that ….e.g. It is no good telling lies. (撒谎没好处。
)It is a pity that you didn’t go to see the film yesterday. (你昨天没看成那部电影真遗憾。
it的用法及强调结构(附常见考点解析及精选练习题)
it的用法及强调结构I. 作代词1. 用作人称代词，代替前文提到过的事物（是同一物）。
My pen is missing. I can’t find it anywhere.I was disappointed with the film. I had expected it to be much better.2. 代词it有时不特指某件东西，而代表前面提到的整个事情。
Tom’s mother kept telling him that he should work harder,but it didn’t help. (but连接两个并列分句，而不是非限制性定语从句，用it)The weather turned out to be very good,which was more than we could expect. （前面用逗号隔开，没有并列连词，是非限制性定语从句，which指代前面整个主句所表达的内容，用which不用it）3. 用来代替指示代词this,that.--- What’s this ?--- It’s a book.4. 表示时间、距离、天气、价值等。
It’s ten o’clock now.（指时间）---How far is it from here to the station?---It's about two kilometers.（指距离）It is rather cold today, isn't it?（指天气）---What's the cost of the dictionary?---It is twenty dollars.（指价值）5. 可用来指做某个动作的人或与某事有关系的人。
---- Who is making such a noise ? --- It must be the children.II. 引导词it1. 作形式主语，代替由不定式短语、动名词短语或从句表示的真正主语。

It的用法It的用法在高考中也是重现率较高的语言点，尤其是it用于强调句。
其考查方式多通过“单项填空”进行，偶尔也出现在“短文改错"和“完形填空"中。
一、要点点拔1．代替上文中提到过的人或事物.指代人时，一般用于小孩或身份不十分明朗的人。
1）－Who is the baby？－It‘s my teacher’s son．2）－Who is that gentleman?－It’s my friend Tom．He(不可用It） wants to see you．2．用于表达天气、环境、时间、距离、季节等.例如：1） It's half an hour’s walk from here to our school．2） It‘s nice and warm here．3) But it’s two o’clock now， and it’s time for us to go to school．3．用作形式主语。
it 没有具体意义,而只是帮助把真正的主语移至句子后尾,使句子显得平稳一些，能借it 给移至句子后尾的主语有三种:一种由不定式表示，一种由动名词表示，一种由从句表示。
1)。
It 替代真正的主语-—动词不定式短语。
It is easier to say than to do 。
It is a good act to help the others.2）.it 替代真正的主语——动名词短语，以动名词短语做主语的句子,主要在以no good, no use， no harm, dangerous， foolish 等词作表语的句中.It’s no harm drinking running water in that area。
It’s foolish talking like that.3)。
it 替代从句作主语，用从句做主语的带it 的句子很多，常见的有下面几类：① It is a pity (a shame ，a fact ，a wonder ，a good thing，etc. )that…It is a shame that he didn’t pass the exam。
② It is strange ( surprising,obvious ,true, good，possible,clear，etc。
) that…。
It was clear that they had no desire for peace.③ It seems (happened ,turned out，etc.)that…It seemed that things were not as they expected。
④ It is said ( decided ，expected ，etc)that …It is said that the tickets have been sold out 。
4。
用作形式宾语。
当复合宾语中的宾语是不定式,－ing短语或从句往往用it作形式宾语,而将真正的宾语移至句末,句子重心后移。
1) We find it difficult to learn English well in such a short time．2) We think it no use crying over spilt milk．3) We made it clear when and where we were going to have the meeting．5．用于强调句型,即“It is/was＋被强调部分＋that/who/whom+其它"句型之中。
使用该句型有以下几点请注意:①强调句的谓语is或was永远用单数.It was yesterday that I met your father in the street．②不管被强调部分是哪种状语，只能用that连接,不得使用where、when等连词.It was in the street that I met your father yesterday．③被强调部分为人时,可用who（主格或宾格）和whom（宾格）代替that，用that也行.1)It was your father that/whom /who I met in the street yesterday．2） It was I that/who met your father in the street yesterday．④强调句中也要注意主谓一致、人称一致和否定转移的问题.1)It is they who are our friends．2） It was not until ten o’clock that we got home last night．⑤注意不要混淆强调句和其他从句。
It is was…that…为强调句标志,去掉后仍可组成一个完整的句子，只是没被强调,而其他从句一般不具备这一特征。
比较：1) It was ten o’clock when we got home last night．我们昨晚到家时已十点了。
2） It was at ten o’clock that we got home last night．我们昨晚是在十点到家的。
第一句不是强调句，when不可改为that，因为去掉it was和that后，只能组成“We got home ten o'clock last night．”这样一个不完整的句子;第二句是强调句，that不可改为when．二、常用句型及考点I。
形式主语型1. It is clear （obvious，true，possible，certain…) that…2. It is important （necessary,right,strange，natural…）that…掌握本句型,应该记住所列举的形容词，并且记住that后的从句应用虚拟语气 (should+动词原形)，should可以省去。
3。
It is no good (use) doing sth．4. It is a pity （a shame …）that…本句型中，that后的从句一般用虚拟语气（should十动词原形），should可以省去。
表示出乎意料，常译为“竟然”。
没有这种意义时，则不用虚拟语气。
5. It is time (about time，high time) that…本句型中that后的从句应该用虚拟语气。
6。
It is the first （second…）time that…7. It is said (reported,learned…．）that…8。
It is suggested （ordered…) that…本句型中的过去分词应该是表示请求、建议、命令等的词，that后的从句要用虚拟语气(should十动词原形)，should可以省略.常译为“据建议;有命令……"。
9. It happens （seems，appears）that…10。
It takes sb…to do sth．11. It doesn’t matter whether…12. It is kind （of sb） to do sth．本句型中的不定式如果需要逻辑主语，则须要前置介词of，而句型中的形容词必须是能表示逻辑主语特征的形容词，常见的有bad,brave，careless，clever，cruel，foolish,honest，horrible，kind，lazy，modest，naughty， polite，rude，silly, stupid,wise，wrong等。
