Retell the working principle of the Longji Rice Terraces.
During the rainy season, rainwater moves down the mountains along hundreds of waterways that connect with each other and the terraces. The sun heats the water and turns it into vapour. This forms clouds from which rain falls down onto the mountain terraces once again.
A preposition + which
Why did the local people build terraces
Why do the local people still keep their traditional way of
growing rice
b …these terraces still mean a lot to the local people
for whom traditions hold much value.
a …they could increase the areas in which they could
grow rice.
What do “which” and “whom” refer to in each sentence
Why do we use prepositions before “which” and “whom”
(They could grow rice in the areas.)
in which
(Traditions hold much value for the local people.)
for whom
a …they could increase the areas in which they could grow rice.
In sentence (a), can we replace “in which” with “where” without changing the meaning
in which
＝where
Yes.
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.

定语从句 Ⅲ
在限制性定语从句中，除了用常见的关系代词或关系副词来引导定语从句外，有时也会使用
“介词+关系代词”来引导定语从句。
Focus on
基本含义和用法
This road will take me to the place ____ which I belong.
根据大意，从句意为“我属于的地方”。根据短语“belong to”可知空格处应填 to。
to
确定介词原则二：
根据从句动词、形容词等构成的短语确定所需介词。
Jack is the very person _________ I will turn when in trouble.
据题干大意，从句意为“我遇到困难可以求助的人”。“求助”即“turn to”，又因先行词指人，故答案为 “to whom”。
to whom
The song often takes me back to the day when the accident happened.
The song often takes me back to the day _____ which the accident happened.
据第一句可知，第二句中which用来指先行词“the day”，在从句中意为“在这天”，故填介词“on”。
确定介词原则三：
根据先行词确定所需介词。
on
此时“介词+关系代词”结构往往可以和
关系副词互换。如：
when=表时间的介词(in, at, during等)+which
where =表地点的介词(in, at, on, under等) +which;
why=表原因的介词 for+ which
1. I met the child (whom) I looked after ten years ago.
我遇到了十年前我照料过的那个孩子。
2. This is the pen (that/which) you are looking for.
这是你正在找的钢笔。
含有介词的动词固定短语在定语从句中一般不拆开，在这种情况下，介词仍然放在后面，如 hear from，look after， look for等。
