Ⅴ.阅读理解

Plastic is used for food packaging (包装) and water bottles as well as many other things you use every day. Look around, plastic is all over! Sadly, much of plastic waste is thrown into waste lands or washed into the sea, breaking down into particles. Particles are often taken in by animals or fish. Unless you are the one who only eats vegetables, it is highly likely that you are also eating this plastic. Besides, when you drink soft drinks from a plastic bottle, you also have the danger of drinking a dangerous chemical. It has been proved that plastic is connected with some types of diseases and young children's growth.

A plastic bottle can break down into enough small pieces on each seaside in the whole world. They have also been discovered to collect in large amount in sea locations where winds and currents (洋流) are weak.

How do you help to solve the problem? Use a stainless steel (不锈钢) bottle. It is an obvious way to deal with the problem that has been ignored for many years. Many countries become increasingly more familiar with the pollution that is damaging the environment. It's easy to understand why steps are being taken to discover things to replace the plastic.

If you use a stainless steel water bottle, you can help cut the number of using plastic bottles, which are thrown away and break down gradually. It may even take 1,000 years to fade away. In a word, even by doing something as small as changing your water bottle to a stainless steel one, you could make the world a better place to live for future generations.
