paper napkins, you know.

using them last year.
1e
1. Stop riding in cars
stop doing sth是“停止(正在)做的某事”，doing是stop 的宾语，是要停止的动作。 辨析：
stop to do sth 是“停下来开始做某事”，（ 停下现在做的事情去做另外一件事）to do是stop的状语，表示目的，是要开始做的事情
例如：
They stop to smoke a cigarette.
他们停下来，抽了根烟。 I must stop smoking. 我必须戒烟了。

2. Recycling paper is really easy.
recycle 作动词，意为“回收利用；再利用”，过去式为recycled，过去分词为recycled，现在分词为 recycling，第三人称单数为recycles。
如：Chemical constantly circulate or recycle in the system. 化学物质在系统中不断循环或回流。
The sole reason the Recycle Bin exists is to implement an undo facility for deleted files. 回收站存在的唯一
理由就是实现文件删除的撤销工具。
