如何判断选择哪个介词？
当关系代词在定语从句中做介词的宾语时，通常用“介词+关系代词”引导定语从句。若先行词指“人”，用“介词+whom”；
若先行词指“物”，用“介词+which”。
1. 从句修饰先行词，关系词在从句中做成分，且在从句中作宾语时可以省略；
I'll never forget the day (that) we spent together.
2. 可以用that引导；
That is the very tool that we are looking for.
限制性定语从句
1. 从句修饰先行词或者前面的整个句子，或其中一部分。此时用关系代词which或as引导。
He suddenly fell ill, which kept him from school.
2. 不可以用that引导，主句和从句要用逗号隔开；
His dog, which he liked very much, died yesterday.

Read the passage and rewrite the underlined sentences using attributive clauses.
Good Deal is a local movement in some countries.
It works to help farmers and workers in less developed areas receive a better deal for their produce. Good Deal products may be a little more expensive than regular products, but up to one-third of the sale price will be given back to the producers. This is more than they could get under the conventional trading system.
The movement has proven popular among young
people, and they want to help producers get the
payment they deserve. They have no problem spending
a bit more on Good Deal products, believing that their
purchasing of these products will help improve local
people’s welfare.
However, some people are less optimistic, and argue that it discriminates against producers not part of the Good Deal movement.
