　　We need to be responsible for our environment. Being a frugal consumer(节俭的消费者) is one way to help. But, what exactly does that mean?

　　Use It Up

　　You can use things up instead of wasting them. Squeeze that last bit of toothpaste out of the tube. Use the last little piece of soap. Don't throw away any bits of the biscuit at the bottom of the box.

　　Wear It Out

　　You do not always need to have new things. Suppose your sneakers have broken laces, but they still fit you. Repair them and wear them longer. You don't have the latest iPhone until the old one doesn't work anymore. Then you can get a new one. Think twice before replacing something that still works.

　　Make It Do

　　When something you want is not on hand, look for something else that you already have to take its place. Suppose you are packing your lunch for tomorrow and want a butter sandwich. You are out of butter. Have a cheese sandwich instead so that you can use all of the cheese. Learn to fix broken toys instead of just throwing them away. With a little thought, you can make something do, instead of buying something new.

　　Do Without

　　Think about all those things that you would like to have. Do you really need them? How long will you really play with that new toy you saw on TV? Making the things that we want uses up your world's resources(资源). And, getting rid of the things we don't want any more takes up even more resources and space.

When you watch TV and play video games you make global(全球的) warming worse! It may seem hard to believe, but when electricity is made, so are greenhouse gases(温室气体). This means that every time you use electricity you help make global warming worse!
Cars are also making global warming worse. They burn fossil fuels(化石燃料) in their engines, and send lots of greenhouse gases into the air.
Global warming may be a big problem, but we can all help stop it. People can try to drive their cars less. Or even get ones that run on sunlight! You can also help. Let’s try one of these top ideas:
(1) Try to use less electricity. Turn off lights, your television, and your computer when you’ve stopped using them. To make electricity, fossil fuels are burned in big factories. But burning fossil fuels also makes greenhouse gases. You should also try to watch less TV.
(2) Plant trees. Not only is it a fun thing to do, but it is also a great way to lower the number of greenhouse gases in the air. Trees take carbon dioxide out of the air when they grow.
(3) Don’t throw away your rubbish, try to recycle it. If rubbish is not recycled, it is put in the ground. There it rots(腐烂) and makes a greenhouse gas called methane(甲烷).So try to recycle cans, bottles, plastic bags and newspapers. It’ll make you feel great! And it’ll help the Earth.
【小题1】If we _____, we may make global warming worse.

There are many ways for us to reduce(减少) waste. For   16 , we can reduce paper and plastic bags. We can also recycle newspapers, glass, and cans(易拉罐) to make new things. Here are some useful ways to   17  waste.
Write on   18  sides of paper
Many people write on only one side of their paper. Why not stop wasting the other side? Some students only use half the pages of their   19  before getting new ones. Try to use up all the paper. People often give cards on birthdays or festivals. How about trying to   20  e-cards instead?
Don’t throw away your old batteries.
Maybe you do not know that old batteries make the earth   21 . This is because they have poisonous parts in them. So, don’t throw away batteries.   22  them together. Try to use rechargeable(充电的) batteries for your games and CD players.
Give off all your unwanted clothes
There are many poor families in China. You may ask your mother to   23  your unwanted clothes. Then you can pass them on to those poor children. You will feel
  24  that you are helping someone else. Also, you can understand   25  your friends or relatives(亲戚) want them before throwing them away.
