U N I T
Attributive clauses (3)
To master attributive clauses with a preposition + whom/which;
To use this type of attributive clauses correctly;
To learn words and expressions about geographical features.
Look at the sentences from the reading passage and answer the questions.
a. Building the terraces therefore meant that they could increase the areas in which they could grow rice.
b. Although modern technology could help produce more crops, these terraces still mean a lot to the local people for whom traditions hold much value.
1. What do “which” and “whom” refer to in each sentence
“Which” refers to “the areas” in sentence (a), and “whom” refers to “ the local people” in sentence (b).
2. Why do we use prepositions before “which” and “whom”
Because “which” and “whom” serve as the object of the action phrases that end with a preposition.
a. Building the terraces therefore meant that they could increase the areas in which they could grow rice.
b. Although modern technology could help produce more crops, these terraces still mean a lot to the local people for whom traditions hold much value.
3. In sentence (a), can we replace “in which” with “where” without changing the meaning
Yes.
Compare them with the following sentences and answer the questions.
c …they could increase the areas. They could grow crops in these areas.
d …these terraces still mean a lot to the local people. Traditions hold much value for them.
4. What is the difference between the two groups of sentences
5. Why does the author choose to use sentences (a) and (b) in the reading passage
Sentences (a) and (b) both contain a clause defining a noun in the sentence. Sentences (c) and (d) are constructed with a pair of simple sentences, with one defining a noun in the other sentence in each pair.
4. What is the difference between the two groups of sentences
Because there is a closer link and connection between the item and the clause defining it in sentences (a) and (b). It will also make the passage clearer, and create an emphatic effect on the objects being defined.
5. Why does the author choose to use sentences (a) and (b) in the reading passage
“介词+关系代词”引导的定语从句
在定语从句中，当关系代词作动词短语或介词的宾语时，为了使关系代词与先行词的关系更加密切，通常用“介词+关系代词”引导定语从句。
1. 若介词放在关系代词前，关系代词指物：介词+which，关系代词指人：介词+ whom。
e.g. This is the reason for which I was praised by my chemistry teacher.
The man by whom the thief was caught was a good policeman.
Is this the pen with which you wrote the letter
This is the man from whom I learnt the news.
e.g. He is the person from whom I learn a lot.
(learn from)
Testing is still the usual means by which students’ progress is measured. (be measured by)
Air, without which man can’t live, is really important.
2. 介词+关系代词：介词根据从句中谓语动词的搭配习惯、先行词与介词的搭配习惯或句子要表达的意思来选用。
3. 含有介词的动词固定短语在定语从句中一般不拆开，介词仍然放在后面，如hear from, look after等。而在介词处于句尾时，句中的关系代词可以省略。
e.g. I met the child (whom) I looked after ten years ago.
I wanted to visit the house (which) my grandparents lived in.
e.g. Beijing is the city, in which (= where) he has lived many years.
I remember the day on which (= when) I went abroad.
The reason for which (= why) he didn’t come isn’t clear.
4. 引导定语从句的“介词+ which”有时也可以用关系副词来代替。
e.g. She has two sons, both of whom are doctors.
There are many kinds of birds in this country, many of which are endangered.
I picked up the peaches, some of which were badly bruised.
The buses, most of which were already full, were surrounded by crowds.
5. “介词+ which / whom”前还可加some, any, none, all, both, neither, many, most, each, few 等。
1. These terraces were built by the local Zhuang and Yao people, to whom Guangxi is home.
2. But perhaps what is most significant is the way in which people have worked in harmony with nature to make these terraces and grow rice.
Now look for more sentences with attributive clauses in the reading passage.
way作先行词，后的定语从句缺少状语时，定语从句的引导词可以省略，也可以用in which。
e.g. I dislike the way (in which) you speak to your mom.
3. This forms clouds from which rain falls down onto the mountain terraces once again.
4. These terraces also provide a perfect environment for birds and fish, some of which feed on insects that can harm the rice crops.
Connect the sentences with a preposition + whom / which.
1. The Zhuang is an ethnic group. Its population is the largest of all ethnic groups in China.
The Zhuang is an ethnic group of which the population is the largest of all ethnic groups in China.
2. Guangxi is a province. The Longji Rice Terraces are located in it.
Guangxi is a province in which the Longji Rice Terraces are located.
It’s OK to say: The Zhuang is an ethnic group whose population is the largest of all ethnic groups in China.
3. I want to visit this cultural landscape. The title of UNESCO World Heritage Site was given to it in 2016.
I want to visit this cultural landscape to which the title of UNESCO World Heritage Site was given in 2016.
4. He is an expert on rice planting. The local Zhuang people have learnt a lot from him.
He is an expert on rice planting from whom the local Zhuang people have learnt a lot.
