as is mentioned above   正如上面提到的

但如果从句为主动语态，一般用 which作主语。

分考点4  “介词+关系代词”的用法

Point 1  “介词+关系代词”引导定语从句时，介词的宾语只能用 which或whom，且不能省略。

●She still remembers the day on which she won the prize.    她仍然记得她获奖的那一天。

●The man with whom she entered the hall was her husband.   和她一起走进大厅的那位男士是她的丈夫。

【特别注意】

宾语时可以省略。

●This is the boy( that/whom/who) his parents are proud of.    这就是他父母引以为豪的那个男孩。

●This is the pen( that/which) I wrote my homework with.     这就是我写作业用的那支钢笔。

(2)、在非限制性定语从句中，“介词+关系代词”中的介词不能移到从句的后面。

【归纳总结】

“介词+ which/whom”引导的定语从句中介词的确定：

①、根据从句中动词、形容词等与介词的习惯搭配来确定

●Do you know the girl with/to whom the teacher talked just now?

你认识刚才和老师谈话的那个女孩吗?(talk作“交谈”讲时，常与with或to搭配)

②、根据语意表达的需要来确定。

●Knowledge is the wings with which we realize our dreams.

知识是我们借以实现梦想的翅膀。(with表示用某种手段、工具)

Point 2   “介词短语+关系代词 which'"结构在定语从句中作地点状语时，从句常用倒装语序。

●He is studying in the classroom now, in front of which stand two trees.

他现在正在那间教室里学习，教室前面有两棵树。

Point 3  “介词+ which+名词”结构引导的定语从句。常见的这类结构有:

for which reason由于这个原因            in which case在这一情况

●He may win the competition, in which case he is likely to get into the national team.

Point 4  “the+名词+ of which/whom”结构引导的定语从句，一般为非限制性定语从句。该结构中的名词和

后面的关系代词为所属关系。

定代词(all, both, none, some, most, several等)；数词(基数词、序数词、百分数、分数)；the+形容词最高级/比较级。

约翰邀请了大约40人参加他的婚礼，其中大部分是家族成员。

考点2  关系副词

当关系词在定语从句中作状语时，要用关系副词。关系副

词有时可以用“介词+关系代词”替换。

Point 1  关系副词when指时间，在定语从句中作时间状语，相当于“表示时间的介词(in, at, on, during等)+ which”

●He lived in the times when （=in which） the blind couldn't get much education.

在他生活的那个时代，盲人没受过多少教育。

●The days are gone when （=during which)physical strength was all you needed to make a living.

完全靠体力谋生的时代已经一去不复返了。

Point 2  关系副词 where指地点，在定语从句中作地点状语，相当于“表示地点的介词(in, at, on, under等)+ which'”

●I walked up to the top of the hill with my friend, where (=at which)we enjoyed a splendid view of the lake.

我和朋友一起登上了山顶,在那里我们欣赏到了壮丽的湖光美景。

●Many of these bags end up in the ocean where( =in which)larger ones can trap sea creatures,such as turtles and dolphins.

这些袋子中很多的最终归宿是大海,在那里，大一些的袋子会困住海洋生物，如海龟和海豚。

【特别注意】

若先行词为一些表示地点的抽象名词，如situation, point, stage, position等，且引词在从句中作状语，

则常用关系副词 where或“介词+关系代词”引导定语从句。如果引导词在从句中作主语、宾语或表语，则用关系代词that/ which引导。

●I have come to the point where（=at which） I can't stand him.

我已经到了无法容忍他的地步。

●He's got into the situation where（=in which） he is in debt.

他已经陷入负债累累的境地。

●At last he got the position （that/which) he had been dreaming of.    他最终得到了他梦寐以求的那个职位。

Point 3  关系副词why指原因,在定语从句中作原因状语，相当于for which.

●Is this the reason why（=for which） he refused our offer?    这就是他拒绝我们的提议的理由吗?

●Do you know the reason why（=for which） he didn't attend the meeting?     你知道他没参加会议的原因吗?

核心考法  重难突破

考法1 考查关系代词和关系副词的用法

关系代词that/ which/who/whom/as在定语从句中作主语、宾语或表语;；whose作定语,表示所属关。关系副词 where/when/why在定语从句中作状语。做题首先要找准先行词，然后分析定语从句的成分，如果从句缺主语、宾语、表语或定语，则用关系代词；如果从句缺状语，则用关系副词或“介词+关系代词”。

另外，考生应重点掌握that与 which、as与 which引导定语从句时的区别。

【全国新高考I 2020·39】The80,000 objects collected by Sir Hans Sloane, for example, formed the core collection of the British Museum __________opened in 1759

【解析】句意为:例如,汉斯·斯隆爵士收藏的8万件藏品是1759年开放的大英博物馆的核心藏品。分句子成分可知,设空处引导定语从句,修饰先行词 the British Museum(指物)且在从句中充当主语,故填 which或that。

【全国I 2020·63】 Because the moon'' s body blocks direct radio communication with a probe, China first had to put a satellite in orbit above the moon in a spot ______it could send signals to the spacecraft and to Earth.

【解析】句意为:由于月球自身遮挡了(地球)与探测器之间直接的无线电通信,中国必须先将一颗卫星送入月球上方轨道的一个位置,在那里它能够向航天器和地球发送信号。分析句子成分并结合句意可知,设空处引导定语从句,修饰先行词spot,且引导词在从句中作地点状语,应用 where引导,故填 where

【全国Ⅲ 2020·61】 In ancient China lived an artist ________paintings were almost lifelike.

【解析】句意为:中国古代有一位画家,他的画作几乎栩栩如生。分析句子结构并结合句意可知,设空处引导定语从句,修饰先行词 artist,,且在从句中作 paintings的定语,两者之间是所属关系,应用 whose引导定语从句。故填 whose.。

考法2考查“介词+关系代词”引导的定语从句

解答此类题注意两点:

(1)、选择介词时,主要看与先行词、从句中谓语动词或形容词的搭配;

(2)、选择关系代词时，先行词是物，则只能用 which；先行词是人，则只能用whom。表所属关系时，用 whose。
