Questions 32to 35are based on the following passage. 

Every year, Americans throw away 50billion food and drink cans, 27billion glass bottles and jars, and 65billion can covers. More than 30%of our waste is packaging materials. Where does it all go? Some 85%of our garbage is sent to a dump,or a landfill, where h can take from 100to 400years for things like cloth and aluminum 铝to decompose . Glass has been found in perfect condition after 4,000years in the earth! We are quickly running out of space. It’s time to learn the three R’s of the environment reduce, reuse,and recycle. 

Reducing the amount of waste you produce is the best way to help the environment. For example you can buy products that don’t have a lot of packaging. You can also look for things that are packed in materials that don’t require a lot of energy or resources to produce. Instead of buying something you’re not going to use very often, borrow it from someone you know. Save energy by turning off lights that you are 8not using. 

Instead of throwing things away,try to find ways to use them again! Bring cloth bags to the store with you instead of taking home new paper or plastic bags. You can use these bags again and again. Plastic containers and reusable lunch bags are great ways to take your lunch to school without creating waste. Use all writing paper on both sides. 

In some towns you can leave your recyclables in bins outside your homeland a truck will come and collect them regularly. Other towns have recycling centers where you can drop off the materials you’ve collected. Things like paper and plastic grocery bags, plastic and aluminum cans and bottles can often be brought to the grocery store for recycling. Whatever your system is,it’s important to remember to clean and sort your recyclables! 
