关系代词which指人的五种情况
关系代词which指人的五种情况黑龙江省宾县第一中学刘世岩在教学中遇到这样一道题：“The child ______is lying in the cradle is my little son.”有百分之九十的同学用who；有百分之五的同学用what，只有百分之五的同学用which。
根据关系代词which的用法特点：在定语从句中指物，可做主语，也可以做宾语。
例如：My little son did not listened to the teacher very carefully yesterday, which I think was wrong.我的小儿子昨天没有认真听讲，我认为是不对的。
（which引导非限定性定语从句，在从句中做主语）。
The book which I bought yesterday is very interesting.我昨天买的那本书很有趣。
（which引导限定性定语从句，在从句中做宾语, which可以省略）。
但关系代词which在中学阶段指人的用法并不多见，现将其用法归纳如下：当先行词是人时，在定语从句中可用关系代词which或者that，而不用who来引导。
可分为五种情况：1．当强调职业时。
例如：His daughter became a doctor after graduation, which he liked very much.他的女儿大学毕业之后当了医生。
这是他非常喜欢的职业。
Her mother is a teacher, which is most glorious under the sun.她的妈妈是个老师，老师的职业是天底下最光荣的职业。
2．当先行词是婴儿或小孩时。
例如：The baby which is lying there has been crying for about twenty minutes.躺在那儿的那个婴儿已经哭了大约二十分钟了。

不能用关系代词Which的几种情况不能用关系代词Which 的几种情况1.当先行词为all, little, much, few, everything, none 等不定代词时关系代词用that而不用which. I will tell him allthat you told me at the ball.There are few books that you can read in this book store.2.当先行词既有人又有物时,关系代词用that, 不用which.He asked about the factories and workers that he had visited.3.当先行词有形容词最高级修饰时,关系代词用that, 而不用which.This is the best novel that I have ever read.Guilin is one of the most beautiful cities that I have ever visited.4.当先行词有序数词修饰时,关系代词用that, 不用which.The first sight that was caught at the Great Wall has made a lasting impression on him. 5.当先行词被the only, thevery, the same, the right等修饰时,关系代词用that,不用which.That is the very thing that we can do.It is the only book that he bought himself.6.当先行词被all, every, any, much, little, few, no等修饰时,关系代词用that,不用which.You can take any room that you like.There is no clothes that fit you here.7.当主句是以which开头的特殊问句时,定语从句关系代词一般用that而不用which.Which of the books that had pictures was worth reading?8.在强调句型" It is ... that ..." 中,只用that,不用which.It is in this room that he was born twenty years ago.9.在" such (the same) ... as ..." 句型中,关系代词要用as, 而不用which.We need such materials as (not which) can bear high temperature.10.表示" 正如... 那样"," 正象..." 之意时, 用as, 不用which.Mary was late again, as had been expected.11.As 引导的定语从句可以放在主句前面, 也可以放在主句后面或主句中间,而由which引导的定语从句只能放在主句后面。
As we all know, oceans cover more than 70% of the earth.used to/be used to的分别used to do："过去常常"表示过去习惯性的动作或状态，但如今已不存在。
Mother used not to be so forgetful.Scarf used to take a walk.(过去常常散步)be used to doing：对……已感到习惯，或"习惯于"，to是介词，后需加名词或动名词。
He is used to a vegetarian diet.Scarf is used to taking a walk.(现在习惯于散步)used to 的用法否定式简写为usedn't）过去经常，以前常常We used to go there every year. （我每年都去那儿。
）He is not what he used to be.他已不是旧日的他了。
我们公司过去和他们的公司常有业务往来。
This used to be a shabby house. （此房年久失修）used to, would这两个词语都可以表示过去常做某事，有时可以换用。
used to do 强调整过去习惯性的行为或状态，但是现在没有这种行为或状态了。
因此，这个短语的内涵是今昔对比。
五妙招帮你搞定感叹句五妙招帮你搞定感叹句一找·二断·三辨·四确定：构成感叹句的感叹词有两个：what和how，其基本结构是：1）What＋名词＋陈述肯定式：2）How＋形容词（或副词）＋陈述肯定式很多初学者常常对该用what还是该用how弄不清楚。
如：①____cold water this is！A．How B．What②____cold it is！A．What B．How如果我们采取“一找·二断·三辨·四确定”的方法很快就能确定该选哪个感叹词。
“一找”即先找出句中的主语。
“二断”就是在句中的名词（形容词、副词等）与代词（或名词）之间断开。
例如上面第一句应在water与this中断开（因this是指示代词），断开后辨别断线前面的词的词性，也就是所谓“三辨”，句①中断线前的词是water，而water是名词。
第四步，就可迅速确定如果是名词就选what。
所以第一例句就选B。
用这个方法我们会对上面第二个例句作出如下判断：____cold｜it is！断开线其前cold是形容词，故应填How。
上面两个例句是最基本最简单的填空题形式。
但只要掌握这个方法，即使再复杂的填空题也会迎刃而解。
不过还要注意，如果断开后，断线前的那个中心词是单数可数名词，千万别忘了在感叹词与名词间加冠词a（an）。
例如：____nice present it is！A．How B．WhatC．How D．What a用上述方法，从present与it之间断开，断线前present是名词，且为单数可数名词，nice又以辅音开头，故选D。
（2）“断→找→去→添→改”五步法：若把一个陈述句变为感叹句，可以采取这“五步法”。
如：The picture is very beautiful．断：在陈述句中的谓语动词后将句子断开：The picture is｜very beautiful．找：划出断线后的中心词是何词类。
去：中心词是形容词或副词时，要把修饰该形容词或副词的词去掉。
（比如本句中心词beautiful是形容词，修饰该词的是very，变时应去掉very。
但须注意，线后如果是名词，名词前的修饰语是万万不能去掉的。
添：就是添上感叹词。
如果线后的中心词是名词，就添What；是形容词或副词就添How。
改：将陈述句句前的大写改为小写，将变为感叹句的感叹词及其修饰的名词部分放在句首，感叹词首写字母改为大写。
同时句尾的标点由陈述句的句号改为感叹句的感叹号。
据此，上句就变成了：How beautiful the picture is！再如：要把“He is a good student．”变成感叹句，可如上法炮制：He is｜a good student．中心词是名词student，a good 为修饰student的修饰语，不能去掉，故变成感叹句应选感叹词what，变成：What a good student he is！（3）一断·二加·三换位：例：1）This is a beautiful flower·2）This flower is beautiful．“一断”：在谓语动词后将此句划断。
1）This is｜a beautiful flower．2）This flower is｜beautiful．“二加”：在第二部分前加引起感叹句的“What或How”；中心词为名词时加“What”；是形容词、副词加“How”。
1）What a beautiful flower…2）How beautiful…“三换位”：将第一部分与第二部分对换位置。
1）What a beautiful flower this is！2）How beautiful this flower is！（4）句型记忆法：因how和what的词性及其在句中的功能不同，由它们引起的感叹句句型可归纳为7种。
如果记住这7种句套子，做任何感叹句题都易如反掌。
例：从题前A、B、C、D所表示的词或短语中选择正确答案，完成下列各句：A=What B=What a C=What an D=How①____pleasant surprise you gave me！②____good news we have got！③____good a TV set we’ye bought！④____unpleasant experience you had last year！对了，答案依次为BADC。
（5）歌诀记忆法：感叹句中what和how的选用，关键看形容词后面是否有名词。
如果有，用what（a，an）；如果没有，用how（至于副词，其前永远用how）。
记住下面歌诀更方便。
what，how如何选？先在后面把名词找，若有名词用what，若无名词必用how。
what，how提句首，其它紧跟别忘了。
主谓一起挪最后，常常可以被省掉。
比较so和such其规律由so与such的不同词性决定。
such 是形容词，修饰名词或名词词组，so是副词，只能修饰形容词或副词。
其规律由so与such的不同词性决定。
such 是形容词，修饰名词或名词词组，so是副词，只能修饰形容词或副词。
so 还可与表示数量的形容词many，few，much，little连用，形成固定搭配。
so + adj.such + a(n) + n.so + adj. + a(n) + n.such + n. (pl.)so + adj. + n. (pl.)such +n. (pl.)so + adj. + n. [不可数]such +n. [不可数]so foolish such a foolso nice a flower such a nice flowerso many/ few flowers such nice flowersso much/little money.such rapid progressso many people such a lot of peopleso many 已成固定搭配，a lot of 虽相当于many，但 a lot of 为名词性的，只能用such搭配。
