Look at the sentences from the reading passage and answer the questions.
What does “which” refer to in sentence (a)
Grammar: Attributive clauses (3)
a ... they could increase the areas in which
they could grow rice.
b ... these terraces still mean a lot to the local
people for whom traditions hold much value.
What does “whom” refer to in sentence (b)
Why do we use prepositions before “which” and “whom”
Grammar: Attributive clauses (3)
…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.
Because “which” and “whom” serve as the objects of the action phrases that end with a preposition.
In sentence (a), can we replace “in which” with “where” without changing the meaning
Grammar: Attributive clauses (3)
a … they could increase the areas in which
they could grow rice.
Look at the sentences from the reading passage and answer the questions.
Yes.
What is the difference between the two groups of sentences
Grammar: Attributive clauses (3)
a … they could increase the areas in which they could grow rice.
b … these terraces still mean a lot to the local people
for whom traditions hold much value.
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.
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.
Why does the author choose to use sentences (a) and (b) in the reading passage
Grammar: Attributive clauses (3)
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 and underline the sentences with attributive clauses in the reading passage.
These terraces were built by the local Zhuang and Yao people, to whom Guangxi is home.
Building the terraces therefore meant that they could increase the areas in which they could grow rice.
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.
Grammar: Attributive clauses (3)
The terraces are cleverly designed, with hundreds of waterways that connect with each other.
This forms clouds from which rain falls down onto the mountain terraces once again.
These terraces also provide a perfect environment for birds and fish, some of which feed on insects that can harm the rice crops.
Now look for and underline the sentences with attributive clauses in the reading passage.
Grammar: Attributive clauses (3)
Although modern technology could help produce more crops, these terraces still mean a lot to the local people for whom traditions hold much value.
This knowledge is passed down through families, which means that new generations continue to use ancient methods of agriculture to maintain the terraces.
Now look for and underline the sentences with attributive clauses in the reading passage.
