Conversation
Jack: Turn off the lights, Julia. It saves electricity.
Julia: Oh, I usually do that. I was just in a hurry.
Jack: I see. I’ve just read a book which gives ideas about how we can save the environment. For example, you should turn off the shower when you’re washing your hair.
Julia: Oh, I would never do that. I have very short hair. It only takes a few minutes to wash. What else does it say
Jack: You should take your own bags when you go shopping.
Julia: Oh, that’s easy. I’ll do that from now on. What else
Jack: People should stop riding in cars and start riding bikes.
Julia: No way! It would take me 45 minutes to get to school by bike!
Jack: But it’s good for the environment! Besides, I like riding my bike.
Julia: Yes, and you also live close to school!

①Recycling paper is really easy.
recycle /ri 'sa kl/ v. 回收利用；再利用
recycle 是由“re-（前缀）+ cycle（循环）”构成的。recycle 的过去式、过去分词为recycled。
构词法记单词：
re-常放于动词前，意为“再次；重复；又”。
e.g. review 复习 reuse 再利用
We can recycle the plastic bags to make new ones.
我们可以回收利用塑料袋来制造新的塑料袋。
My mother recycles the old bottles into vases.
我妈妈回收利用这些旧瓶子做花瓶。
拓展：recycle 的词形变化：
recyclable adj.可回收利用的；可再循环的
recycling n. 回收利用
recycled 过去分词
常作定语，与所修饰的名词之间在逻辑上存在被动关系。
Paper is recyclable. We should recycle the waste paper in our daily life. The recycling of paper is good for us. The recycled paper can save money. 纸张是可以回收利用的。在日常生活中，我们应当把废纸回收利用。纸张的回收利用对我们有益。这些被回收利用的纸可以节省钱。
