Unit 3 构 词 法
【新知导引】
仔细观察例词并写出汉语意思。
1. grand+son=grandson (n. _____)
2. grand+daughter=granddaughter (n. _____)孙子孙女3. re+use=reuse (v. _________)
4. re+cycle=recycle (v. _____________________)

6. hope(n. )+ful=hopeful(adj. _________)
7. recycle(v. )→recycling(n. _________)再次使用回收利用, 再使用(废品)无望的有希望的回收利用【知识详解】
一、合成构词法
合成构词法是一种比较灵活的构词方法, 可以合成名词、形容词、副词、代词、动词等。例如: blackboard, afternoon等为合成名词; middle-aged和kind-hearted等为合成形容词; everyone, maybe, however等也都是通过合成构词法构成的单词。 掌握合成构词法有助于我们理解和记忆更多的词汇。 二、派生构词法
派生构词法又叫词缀构词法, 即在一个单词的前面或后面加上词缀构成新的单词。加在单词前的词缀叫做前缀; 加在单词后的词缀叫做后缀。一般前缀改变词义, 而后缀改变词性。 1. 常见的前缀 2. 常见的后缀 3. 派生规律
由一个词根加上相应的词缀可以派生出名词、形容词、副词等, 掌握派生方法对扩充词汇量有很大的帮助。
例如: 由名词interest可以派生出:
interest—interesting—interested—interestingly—uninteresting—uninterestingly 例如由名词hope可以派生出:
hope—hopeful—hopeless—hopefully—hopelessly
三、转化法
转化法指的是把一种词性用作另一种词性的方法。常见的转化有:
1. 动词转化为名词。
Let’s go out for a walk after dinner.
晚饭后我们去散步吧。 2. 名词转化为动词。
Please help me water the flowers every day.
请每天帮我浇花。
3. 形容词转化为名词。
Red is my favorite color. 红色是我最喜欢的颜色。【即学活用】用括号内所给词的适当形式填空

Protect the environment
Dear everyone,
As we all know, we need a healthy environment, so it’s everyone’s duty to help build a green city. What can we do? First, we can walk or ride a bike to school as much as possible so that we can reduce air pollution. Second, let’s use the used textbooks instead of the new ones. I think it’s helpful to save trees. Third, we should try our best to prevent people from using plastic bags. Finally, we should turn off the lights or the taps when we don’t use them. In a word, if everyone starts to do something, the world will become cleaner and more beautiful.
