本课语言点
1. They are the hardest substance found in nature.
本句中found in nature是定语从句，修饰substance.定语从句中省略了that are.这种省略现象在定语从句中很常见，在前几个单元中，我们遇到过多次。请看下面的句子：

2） He is a man （that） we all like and trust. （他是一个我们大家喜欢和信赖的人。）
3） This is the most interesting film （that） I have ever seen. （这是我看过的最有意思的电影）
先行词的前面有形容词最高级时，定语从句必须用that引导，而不用which.请看下面的句子：

2） This is the most serious problem （that） we have ever met. （这是我们遇到过的最严重的问题。）
3） They are the richest people （that are） living in this area. （他们是住在这一地区的最富有的人。）

4. For others， having a family simply means having children.

security 是一个名词，意思是“安全”。
that comes from living together， helping and sharing 是定语从句，修饰that feeling of belonging， of love and security.
8. However， with the change from an agricultural to an industrial society， many nuclear families moved away from the family home in order to find work.
