课文简介

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：
1） There are many books （that） I'd like to read. （有很多书我想看。）
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：
1） This is the most beautiful place （that） I have ever visited. （这是我游览过的最美丽的地方。）
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。）
本句中的hardest意思为“坚硬的”“坚固的”，而不是“困难的”。请看下面的句子：
1） This nut is as hard as rock. （这果子硬得像岩石。）
2） He found it hard to make friends. （他觉得交朋友很困难。）
2. That means a diamond can cut any other surface. And only another diamond can make a slight cut in a diamond.
mean是一个很常见的词，本句中的意思是“意味着”。mean还有“意欲，企图，打算”的意思。请看下面的句子，注意mean在各句中的意思和用法：
1） What do you mean by saying this to me？ （你对我说这个是什么意思？）
2） Friendship means everything to him. （友谊对他来说意味着一切。）
3） The teacher's praise meant so much to the children. （老师的表扬对孩子们来说很重要。）
4） I'm serious about this. I mean what I say. （我对此事是认真的，我说话算数。）
5） I'm sorry， I didn’t mean to hurt you. （对不起，我无意伤害你。）
6） They meant to finish the work ahead of time. （他们的打算是提前完成这项工作。）
7） I meant to call you but I forgot. （我原打算给你打电话的，但我忘记了。）
cut在前一个句子中做动词用，意思是“切割”，在后一个句子中做名词用，意思是“切面”。
1） Who will cut the ribbon for the exhibition？ （谁将为展览会剪彩？）
2） I am going to have my hair cut today. （今天我要去理发。）
3） The icy wind cut him to the bone. （他感到寒风刺骨。）
