How green are you Do you know how to be green We all need a healthy environment，but we produce waste every day and it does harm to our environment．As students，though we are young，we can still do something to help．In fact，even the simplest everyday activities can make a real difference to the environment．Here are some ideas for you．
Reduce
Reduce means “use less”．Don't waste things．This saves money and reduces pollution and waste to the environment．Before we buy something new，think whether it is really necessary or maybe the old one will be just as good．
Reuse
Reuse means “use again”．Use things as long as possible．When we buy things，make sure that they last a long time．We should look after them so that they will last，and we should repair them if we can instead of throwing them away and buying new ones．Don't use a paper cup or a paper bag．It's better to use a china cup and a lunch box because you can use them again．
Recycle
Recycle means “change things into something else”．Though it takes energy to change something into something else，it's better than throwing things away or burning them．Find out what can be recycled in your neighbourhood and take part in the recycling programs．We should also buy products made from recycled materials，such as recycled paper，to help save trees．
Now let's remember these three words—reduce，reuse and recycle，and protect the environment together!
(　B　)1．Who is the text written for
A．Parents． B．Students．
C．Workers． D．Scientists．
解析：推理判断题。根据“As students，though we are young，we can still do something to help．”可知，本文是写给学生的。故选B。
(　C　)2．What does the underlined word “china” mean in Chinese
A．精巧的 B．稀有的
C．瓷制的 D．先进的
解析：词义猜测题。根据“because you can use them again”可知，可以反复使用的杯子，应是瓷制的。故选C。
(　A　)3．Which is NOT true according to the text
A．Throw the things at once if they are broken．
B．We should use things as long as possible．
C．Using less can save money and reduce waste．
D．Recycling takes energy but it is helpful to the
environment．
解析：细节理解题。根据“We should look after them so that they will last，and we should repair them if we can instead of throwing them away and buying new ones．”可知，如果东西坏了，我们应该修理它们，而不是把它们扔掉再买新的。因此A项与原文不符。故选A。
(　D　)4．What's the structure of the text
A．①/②③④⑤
B．①②③④/⑤
C．①/②③/④⑤
D．①/②③④/⑤
解析：篇章结构题。根据全文内容可知，第一段介绍最简单的日常活动也能对环境产生真正的影响。第二段、第三段和第四段分别介绍一些建议。最后一段总结我们应该减少、再利用、再循环，一起保护环境。因此文章的结构为总——分——总。故选D。
(　B　)5．What's the best title for the text
A．How Do We Usually Produce Waste
B．How Can We Protect the Environment
C．What Should We Do Before Buying New Things
D．Why Should We Remember the Words “Reduce，Reuse and Recycle”

Everyone can make small changes in their lifestyle and help reduce pollution and waste．
First，we can ride bikes or walk to school rather than going by car，as this can help reduce air pollution．Second，we should turn off the lights when going out as well as turn off the tap when we brush our teeth．Besides，we shouldn't use plastic bags when we go shopping，because plastic is harmful to the environment．Last but not least，we need to plant more trees and flowers to make the environment greener．
If we keep doing this，I believe the environment will be better and better．Let's do everything we can to live a green life and protect our planet．
