可数名词时，指什么用什么．

6. 当先行词是the way,在定语从句中充当方式状语时（引导词通常用that或省略，也可用in which．I don’t like the way (that) you speak.=I don’t like the way in which you speak.=I don’ike the way (which/that) you speak in. t l【“介词+关系代词”十种情况】在定语从句中，介词词的结构浅析如下：
1．介词+which在定语从句中分别作时间、校的那一天。
The factory in which (=where) I work is a large one.我工作的工厂是一个大工厂。This is the reason for which (=why) he was late.这就是他为什么迟到的原因。
2．介词+which（指物）/ whom（指人）在定语从句中作地点状语，表示存在关系，定语从句主谓一般要倒置。
They arrived at a farmhouse, in front of which sat a small boy.他来到一处农舍，前边坐着一个小男孩。
I saw a man, on the head of whom stood a bird.我看见一个人，他的头上站着一只鸟。3．介词+ which（指物）/ whom（指人）在定语从句中作目的、方式或地点状语。这种结构中的介词一般受动词或介词后的名词所制约。如：
Could you tell me for whom you’ve bought this coat?你能告诉我这件衣服是给谁买的吗？The man, from whom I learned the news, is an engineer.这人是一位工程师，我是从他那里得到这消息的。
4．介词+which/whom，用于被动结构的定语从句中，作状语，说明动作的出发者。如：The wolf by which the sheep was killed was shot.伤害羊的那只狼被打死了。The man by whom the wolf was shot was a good hunter.打死狼的那人是个好猎手。5．不定代词+of+which/whom，在定语从句中作主语，说明整体中的部分，常用的不定代词有：both, all, any, some, each, none, most等。如：
There are a lot of books here, none of which belongs to me.这儿有许多书，可一本也不属于我。Yesterday Mary bought a few clothes, all of which were expensive.昨天玛丽买了一些衣服，都很贵。
6．数词+of+which/whom，在定语从句中作主语，说明整体与部分的关系。数词可以是基数词、序数词、分数或百分数。如：
In our class there are fifty-four students, twenty-five of whom are girls.人是女生。
Two watches were stolen, one of which was mine.两只手表被偷了，其中一只是我的。7．名词+of+which代替whose+名词，在定语从句中作定语。如：
I saw some trees, the leaves of which (=whose leaves) were black with disease.我看见一些树，他们的叶子因害病而发黑。
I live in a house, the windows of which are all broken.我住在一所房子里，其窗都破了。8．介词+ which（指物）/ whose（指人）修饰后边的名词。如：
我们班有54名学生，25
他们
地点和原因状语，代替相应的关系副词
when, where
和why。如：I still remember the day on which (when) I first came to school.
我仍然记得初来学
+关系代词结构是一种较为复杂的问题。现就几种常见的介词
+关系代
the way表＂以…方式／方法＂），
It rained all night and all day, during which time the ship was broken into pieces.夜，就在这期间轮船撞碎了。
雨下了一天一
The driver was the man from whose room she had stolen the maps.司机就是那个人，她从他的房间偷走地图。
9．形容词最高级+of+which/whom结构，在定语从句中，作定语，表部分关系。如：China has thousands of islands, the largest of which is Taiwan.中国有成千上万个岛屿，其中最大的是台湾岛。
In our class there are twenty girls, the cleverest of whom is Li Hua.的是李华。
10．介词+which+不定式。此种用法多见于正式文体中，相当于一个定语从句。如：At last he had something about which to write home.他终于有了给家里写信的内容了。He had no key with which to open the door.他没有开门的钥匙。He has a small room in which to live. 【运用定语从句时应注意的几个问题1．关系代词在定语从句中作主语时，（先行词是books，因此动词应用复出现。
This is the most beautiful place that I have visited it.
This is the most beautiful place that I have visited. 这是我参观过的最美的地方。（去掉it，因that代替先行词the most beautiful place在定语从句中作The school where I worked there is a big one.
The school where I worked is a big one.我所工作过的学校是一所大学校。（去掉there，因where既引导定语从句，又在从句中代替in the school作状语。）3．关系代词在定语从句中作主语时不可省略。The books were on the table were given to you.
The books that were on the table were given to you.桌上的那些书是给你的。（关系代词that作主语不能省）
4．“one of the +复数名词”后的定语从句中谓语动词的单复数情况。“one of the +复数名词”时，复数名词是先行词，the +复数名词”前面有而不是复数名词。如：
He is the only one of the students who speaks Japanese in our class.他是我们班唯一说日语的学生。（the only one是先行词）
He is one of the students who speaks Japanese in our class.他是我们班里说日语的学生之一。（students是先行词）
5．定语从句中who和whom的选用。
关系代词who/whom引导定语从句时，作主语用主格的定语从句带有插入语，而又不用逗号分开时，要用Mary is a girl who I think is clever.
在定语从句who I think is clever中, I think是插入语，去掉后Mary is a girl whom I think to be clever.
Mary is a girl who is clever是一
中，如把I think
个完整的句子，who是定语从句的主语，不能用whom替换。但下面的句子，情况就不同了：
在定语从句whom I think to be clever
who，作宾语用宾格who。
whom。在其引导
所以谓语动词常用复数形式。
如果“one of
the very /only等修饰语，则谓语动词用单数形式，因为先行词是，
visit的宾语，再加
it就多余了。）
】
定语从句的谓语动词应和先行词的人称和数保持一致。
这是马克吐温所写的书中的一本。因此要注意避免从句中句子成分的重
were。）
我们班有20名女生，最聪明
This is one of the books which were written by Mark Twain.2．关系代词或关系副词在从句中充当一个句子成分，
看作插入语而去掉，则剩下的部分子结构，所以
Mary is a girl whom to be clever很明显不是一个完整的句
whom作think的
如作主on the day，
I think不能被看作是插入语，而是定语从句在的主谓结构，
宾语，to be clever是whom的宾补。
6．定语从句中关系代词或关系副词的选择取决于它们在从句中所充当的句子成分。语和宾语用关系代词；作状语，用关系副词。
I’ll never forget the day when I went abroad myself.（when在从句中代替时间状语此句可分解为该句可分解为
I’ll never forget the day. I went abroad myself on the day.）I’ll never forget the days. We spent the days together.）
I’ll never forget the days that we spent together.（that代替the days，在从句中作spent的宾语，
