in which的用法
这个牵扯到两个从句的问题
例子：This is the house____he was born in.
这句是定语从句，之所以称之为从句，就是在提醒你要看所修饰的词在后面的句子中做的成分。这里，he was born in（the house）the house是in的宾语，故可填that或which
This is the house____he was born.
where可以看成是个复合关系代词，故可以分解为in which，进而变成介词提前的定语从句
（高中毕业很长时间了，很多概念记不清楚了，可能分析的不对，记得问老师确认一下）

看所修饰的词在后面的句子中做的成分
那个句子我帮你问问，稍等

是定语从句哈，因为刚看的时候以为缺地点状语，没有慎重考虑，抱歉，复合关系代词一定是在定语从句中出现的！
in which，for which，on which，at which有什么区别，怎么使用，用法
区别在于后面的定语从句缺少不同的状语。因为这些介词加关系代词中间的介词很多是由定语从句决定的，which指代前面的先行词。其中包含固定词组，要么和先行词构成固定搭配后在定语从句里做状语；要么和定语从句的谓语构成固定搭配做定语从句的状语。
in which：在......里。
for which：为了......；因为.....。
on which：关于......；在......上。
at which：（具体）在......（年龄/地点等等）。例如：
Select the database in which you want to compare counters.（ in which在定语从句里做地点状语）
选择您想要在其中比较计数器的数据库。
This is an emerging space in which we will likely be seeing some innovation over thecoming months.（ in which在定语从句里做地点状语）
这是一个新兴空间，关于这方面，在未来的几个月我们将能看到一些创新。.
That is the reason for which he dislikes me.（for which在定语从句里做原因状语）
这就是他不喜欢我的原因。
It would work and serve the specific purpose for which it was created, but it would do little to deliver on the original promise of SOA as it had been envisaged several years earlier. （for which在定语从句里做目的状语）
没错，它能完成一定的功能并满足最初的特定目标，但至于履行已展望多年的SOA最初承诺，它就不行了。
The material on which an autograph was signed, and whether the star was living ordead, could have as much of an impact as who signed it.（on which在定语从句里做地点状语，sign on：在......签字）
有明星亲笔签名的那些东西和给这些东西签名的人物具有同样大的影响力，不管这些明星是活着还是已经死了。
Where the analysts seem to have gone off the rails last year is in the price-to-earnings multiples on which they based their predictions.（on which在定语从句里做地点状语，词组base......on......：把什么建立在.....上）
然而，分析师们当时似乎在市盈率倍数这个他们赖以进行预测的关键数据上出了岔子。
Study of the bones of these cattle from ancient times shows the ages at which the animals were killed.（在定语从句里做时间状语，at the age of：在....岁时）
对于这些远古时期驯化牛骨骼的研究结果告诉了我们这些家畜宰杀时的年龄。
which和in which用法的区别
which和in which用法的区别为：意思不同、用法不同、词性不同。一、意思不同1、which：哪一个，哪一些。2、in which：在其中。二、用法不同1、which：which用作关系代词，可引导限制性定语从句或非限制性定语从句，引导非限制性定语从句时which可以用整个主句作为其前行词，相当于and that，有时还可引导不定式短语从句。2、in which：in which用于定语从句，作关系副词，在句中不做成分，in which=where。三、词性不同1、which：which是关系代词或关系形容词，作为代词用作主语或宾语，作为形容词用作定语。2、in which：“介词短语+ which”属于副词性，只能用作状语。
in which的用法！！！！
1、根据which引导的从句而定，当从句中需要以in作介词时使用。例句：The school which he once studied in is veryfamous.= The school in which he once studied is very famous.他曾经就读的这所学校很有名。2、固定搭配例句：The plane may be several hours late, in which case there's no point in our waiting.（固定搭配：in the case) 飞机可能会晚点几小时，这种情况下等待是没有意义的。扩展资料which是定语从句的关系代词之一，有且仅有两种用法。1、which前面有逗号，逗号前面是个名词，which就近指代那个名词。例句：Tankfield emailed Pea some photos, which did not cheer Pea up.坦克福尔德给皮尔邮件了一些照片，却并没有让皮尔高兴起来。2、which前面是介词，介词前面是名词，which就近指代介词前的那个名词，名词和介词之间有无逗号均可。例句：Tankfield once lent Pea a book from which Pea glimpsed the basics of genes.坦克福尔德曾经借给皮尔一本他曾经在上面瞄到过基因理论的书。
英语中in which的用法？要很~~~详细
定语从句中.如
this
is
the
room
in
which
we
stayed
先行词是room，后的句子是用来修饰room的
但是room不可做stay的成分，因为stay是不及物动词，后不可直接家宾语
所以要有个介词．
其实上述的句子＝
this
is
the
room
which
we
stayed
in．
这里的介词是可以提到which
前的
注意，第二个句子可用that
或省略
但第一个只能用which．只有which前可加介词
in which定语从句
1. 的确，in which可以等于when，也可以等于where，但不会等于why.
关键是看定语从句中缺少时间状语还是地点状语。
2. 例如：
1）I'll never forget these days in/during which I stayed with you.
= I'll never forget these days when I stayed with you.
我永远不会忘记我和你待在一起的日子。
其中：in/during which I stayed with you = when I stayed with you
= I stayed with you in/during which = I stayed with you in/during these days
2）This is the city in which I stayed last year.
= This is the city where I stayed last year.
这就是那个去年我待的地方。
其中：where I stayed last year = in which I stayed last year
= I stayed in which last year = I stayed in the city last year.
3. 另外，有的in which找不到合适的关系副词代替。
如：I dislike the way in which you treat me.
我不喜欢你对待我的方式。
其中：in which you treat me = you treat me in which
= you treat me in the way
4. for which = why
如：Can you tell me the reason why you were late?
= Can you tell me the reason for which you were late?
你能告诉我你迟到的原因吗？
其中：why you were late = for which you were late
= you were late for which = you were late for the reason
定语从句中的that和which的区别
定语从句中的that和which的区别为：意思不同、用法不同、侧重点不同。一、意思不同1、that：(指较远的人或事物)那，那个。2、which：哪一个，哪一些，(明确所指的事物)…的那个。二、用法不同1、that：that用作关系代词时在下列情况下可以省略：引导限制性定语从句在从句中用作宾语时，用在there be结构前作主语时，用作表语时，在定语从句与先行词之间有插入语时。2、which：which用作疑问代词时，在特殊疑问句中用作宾语或主语。which用作关系代词，可引导限制性定语从句或非限制性定语从句，引导非限制性定语从句时which可以用整个主句作为其前行词，相当于and that，有时还可引导不定式短语从句。三、侧重点不同1、that：先行词是序数词时或被序数词修饰时，不宜用which。2、which：当关系代词的前面有介词时，不宜用that。
