在面向对象方法中 【2】 描述的是具有相似属性与操作的一组对象。

答案：

参考答案：类

解析：[知识点] 程序设计基础：面向对象方法的基本概念[评析] 将属性、操作相似的对象归为类，也就是说，类是具有共同属性、共同方法的对象的集合。所以，类是对象的抽象，它描述了属于该对象类型的所有对象的性质，而一个对象则是其对应类的一个实例。

Do you still get free plastic bags from the supermarkets? Things have changed.

China has banned free plastic bags at shops and supermarkets, and people have to pay for using plastic bags. The rule started on June 1, 2008. It came because our country tried to make litter less. Making super-thin plastic bags has also been banned.

The Chinese once used about 3,000,000,000 plastic shopping bags a day, and they have caused pollution of the environment. The bags have become a main cause of plastic pollution because they are easy to break and people throw them away here and there. So the Chinese people are encouraged to bring their own bags for shopping.

What kind of shopping bag is the best to bring? Some students in Anhui have a good idea. They make their own shopping bags. They use old clothes to make cloth bags, and send them to their parents as presents. They also ask their parents and friends to use cloth bags instead of plastic ones. They think it is their duty to protect the environment.
