  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.

 1.Do we need to be responsible for our environment?

 2. How do we deal with the last little piece of soap?

 3.When do we need to get a new iPhone?

 4. What should we do when something we want is not on hand?

5.What does the writer want to tell us?

阅读短文,根据短文内容,从短文后的六个选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。(共8分,每小题2分)

  As you grow rapidly through your teenage years, you will experience a lot of changes. The changes may seem difficult.  1   Don’t panic! You will deal successfully with them! You are a young adult now!

  With more responsibility, you will find more freedom to make your own choices. This is a time to be well informed about making choices. In this way you can make healthy balanced decisions.  2   You may already know your career path or you may have no idea at all what you want to do. Both situations are fine! Work hard and the right opportunity will present itself to you.

  Young adulthood means greater freedom and more choices.  3   But try not to shut your family out of your life. You should learn to think of others even though you are old enough to look after yourself.

  It is also perfectly natural at this time for you to spend more time with your friends than your family. Choose your friends wisely. A true friend will stand by you no matter what happens.

  This period is a part of the life cycle. There are some people who will be with you throughout life’s journey. There will be some people with whom you part and go separate ways. Leaving school can be hard. The reality is that you may not even see all of your classmates again.

  You are a young adult. It is your life. No one can live it for you.  4   So making the right choices will be important to you. Life is for living. Enjoy your life wisely.

  A. They will help shape the future.

  B. They may seem to happen quickly.

  C. You will probably want to be independent.

  D. You may appreciate what you have in your own life.

  E. The choices that you make from now on will be your choices.

  F. Your family has been with you since you came into this world.
