 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 tKe tub'e. 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 any more. 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 our 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?

(2014 •南宁)As a student, I was most afraid to answer questions in class, and I found that the students around were just like me. At the beginning of each class,  when the teacher asked a question, I always lowered my head because I was afraid that the teacher saw me.

One day, in a foreign language class, Mr. Black gave us a lesson. He wanted us to be active in class, so he asked us some questions, but no one answered. "Let me tell you a story first," he said.

"When I came to the United States to study, the university often invited famous people to make speeches. Before the beginning of every speech, I found an interesting thing. The students around me always took a cardboard folded (折叠的)in half, wrote their names in bold with the most eye-catching color, and then placed the cardboard on the seat. So when the speaker needed the answers from the students, he could see and call a listener's name directly."

"I couldn't understand that. My classmate told me the speakers were all top people, who meant chances. When your answer was to his surprise, it meant he might give you more chances. In fact, I really saw a few students got great chances because of that."

After listening to the story, I understood that the chance will not find you itself. You must show yourself all the time so that you can find a chance on the card.
