关系副词的概念：
关系副词兼有副词与连接词两种作用，在不及物动词的连接中要求用关系副词。关系副词有when, where, why。
关系副词的特点：
关于副词用于引出定语从句，主要有when, where, why：
如：Sunday is the day when very few people go to work. 星期日是没什么人上班的日子。
That's the reason why he dislikes me. 这就是他不喜欢我的原因。
Do you know a shop where I can find sandals? 你知道哪家商店我能找到凉鞋吗？
注：关系副词用于引出定语从句，且在从句中用作状语。关系副词when表示时间，where表示地点，why表示原因。
使用关系副词应注意的几点：
（1）how不能用作关系副词，不要想当然地将how用作关系副词置于theway后表示方式：他说话就是那个样子。
误：This is the way how he spoke.
正：This is how he spoke./ This is the way（that, in which）he spoke.
（2）关系副词when和where既可引导限制性定语从句，也可引导非限制性定语从句，但why只能引导限制性定语从句，不能引导非限制性定语从句（若引导非限制性定语从句，可用for which reason）。
（3）引导定语从句时，when的先行词为时间，where的先行词为地点，why的先行词为原因（主要是the reason），但是反过来却不一定：
如：Don't forget the time(that) I've toldyou.不要忘记我告诉你的时间。
Do you know the house(that) he bought recently? 你知道他最近买的那座房子吗？
Please tell me there as on(that) you know. 请告诉我你所知道的原因吧。
关系副词的用法：
关系副词有when, where, why，作用有三个：
1、连接主句与从句；
2、代替先行词；
3、在从句中作状语，不可省略。
When和where既可引导限制性定语从句，也可引导非限制性定语从句。Why只能引导限制性定语从句。这些关系副词在意义上都相当于一定得“介词+which”结构。
1）when=at/in/on/during，在定语从句中作时间状语。
例如：Tell me the time when(at which) the train leaves.
注意：
①当表示时间的先行词在从句中中作主语或宾语时，不能用when。
例如：I will never forget the days I spent with your family.
②It/This/That+be+the first/second/last time that…句型中，that是习惯用法，不能用 when代替，that还可以省略。从句中使用与“be动词”呼应的完成形式。
例如：It is the first time that I have been to the Great Wall.
2）where表地点，只能跟在表示地点的名词后，它在定语从句中作地点状语。
例如：This is the second school where I used to teach.
注意：
①引导词where可用that替换，并经常可以省略。
例如：That's the place(where/that) we went before.
②当表示地点的先行词在句中作主语或宾语时，不用where，用关系代词that或which。
例如：The factory that/which we visited yesterday was built last year.
③where可与from连用。
例如：His head soon appeared out of the second story windows, from where he could see nothing but rees.
3）why表原因，引导的从句修饰名词reason。Why可用that或forwhich替换或省略。
例如：I don't know the reason(why/for which/that) he left here.
强调句的概念：
强调句 (The Emphatic Pattern) 是一种修辞，是人们为了表达自己的意愿或情感而使用的一种形式。通过各种方式对句子中的某个部分进行强调，从而起到修辞的作用。英语常用的强调结构有：It is (was)+被强调部分(主语、宾语或状语)+that/who...；what…be…句型；
强调句的使用:
一、强调句句型：
1、用It is／was...that／who...句型表示强调。
（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。
e.g. 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。
e.g. Was it yesterday that he met Li Ping?
（3）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？
e.g. When and where was it that you were born?
注：被强调的部分（通常是句子的主语、状语、宾语或宾语补足语）放在is／was的后面，如被强调的是人，则后面可用who，whom等代替。
如：原句：He met an old friend in the park yesterday.
强调主语：It was he who/that met an old friend in the park yesterday.
强调宾语：It was an old friend that/who he met in the park yesterday.
强调地点状语：It was in the park that he met an old friend yesterday.
强调时间状语：It was yesterday that he met an old friend in the park.
2、用助动词do, does或did来强调谓语动词。
如：Do come early.
He did send you a letter last week.
We're pleased that she does intend to come.
3、用主语从句+be+被强调部分，主语从句常用what引导。
如：What John wants is a ball.
What Mary does every day is(to) give piano lessons.
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：
e.g. 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。
e.g. 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。
使用强调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。
如：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。
如：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。
如：It was your father that/whom/who I met in the street yesterday.
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。
如：It is they who are our friends.
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。
强调句型用法拓展：
1、句首词用“It”，不能用“This”，“That”等。
2、be动词的形式是is或was，不能用复数形式are或were。若原句的谓语动词用了现在时或将来时，则用is；
若原句的谓语动词用了过去时或过去完成时，则用was。
如：It___the Chinese women that___a great role in the socialist construction.
A. is; plays
B. are; play
C .is; play
D. are; plays
答案：C
3、被强调的部分如果是代词，强调主语用主格，强调宾语用宾格。
如：It is him that/who/whom I met in the street yesterday.
It is I who/that am wrong.
4、连接词一般用that，当强调部分是人时，既可用that也可用who。特别注意当强调部分是时间状语或地点状语时，不能用when或where。
如：It was on Oct1st, 1949 that People's Republic of China was founded.
It was at the gate____he told me the news.
A. that
B. what
C. which
D. when
答案：A
5、主谓一致问题被强调的主语要和that后面的谓语动词在数上保持一致。
如：It is Mary who often _____(help) me with my English. （helps）
It is I that ____(be) against you. （am）
6、not...until结构的强调。
强调“not...until”引导的时间状语时，要用“it is/was not until...that...”结构，that后面的句子要用肯定式，且须用陈述句语序。
如：We did not get off the bus until it stopped. ?
It was not until it stopped that we got off the bus. (注意：强调该结构时not until不能分开)
