Plastic

We use plastic wrap to protect our foods. We put our garbage in plastic bags or plastic cans. We sit on plastic chairs, play with plastic toys, drink from plastic cups, and wash our hair with shampoo from plastic bottles!

Plastic does not grow in nature. It is made by mixing certain things together. We call it a produced or manufactured material. Plastic was first made in the 1860s from plants, such as wood and cotton. That plastic was soft and burned easily.

The first modern plastics were made in the 1930s. Most clear plastic starts out as thick, black oil. That plastic coating inside a pan begins as natural gas.

Over the years, hundreds of different plastics have been developed. Some are hard and strong. Some are soft and bendable. Some are clear. Some are many-colored. There is a plastic for almost every need. Scientists continue to experiment with plastics. They hope to find even ways to use them!

英语四级考试每年举办两次，分别在上半年和下半年举行各一次，6月份的考试即将来袭，做好考前备考的同时也要注意调整好心态，勿要慌张。词汇是英语的基础，语法也是非常重要的一部分，小编提醒，不妨利用剩余的备考时间多多巩固基础，在考试中也可灵活运用哦！
