Attributive Clauses(3)
定语从句
Longji Rice Terraces
Review
Main idea
… they could increase the areas in which they could grow rice.
… these terraces still mean a lot to the local people for whom traditions hold much value.
a
b
Observe the sentences and answer the questions.
Q1. What do “which” and “whom” refer to in
each sentence
Q2. Why do we use prepositions before “which” and “whom”
Q3. In sentence (a), can we replace “in which”
with “where” without changing the meaning
Q2: Because “which” and “whom” serve as the object of the action phrases that end with a preposition.
Q3: Yes.
Main clause: They could increase the areas.
Relative clause: They could grow rice in the areas.
which
… they could increase the areas in which they could grow rice.
… these terraces still mean a lot to the local people for whom traditions hold much value.
a
b
... they could increase the areas. They could grow crops in these areas.
...these terraces still mean a lot to the local people. Traditions hold much value for them.
c
d
Compare and answer the questions.
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
Q4: Sentences (a) and (b) both contain a clause defining a noun in the sentence.
Sentence (c) and (d) are constructed with a pair of simple sentences, with one defining a noun in the other sentence in each pair.
Q5: 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.
Now look for more sentences with attributive clauses in the reading passage.
2. This forms clouds from which rain falls down onto the mountain terraces once again. (Para.4, Line 9)
1. 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. (Para.4, Line 1)

2. The English play in which my students acted at the New Year’s party was a great success.
当先行词是表事物的名词或代词时，介词后的关系代词要用which，不能用that。
