    The little boy kept on digging and digging．Suddenly，a few small colorful ston-es   caught his eyes．He collected them and put them into a glass jar patiently．Humming a song，he went on digging．The jar was full soon．Then he talked to himself calmly and proudly，"Maybe I can't finish digging all the way through the earth，but look at what I have found in the process （过程） of digging!"
   The boy's goal was too difficult，but it did cause him to go on，in other words，to cause us to keep working!
   Not every goal will be achieved．Not every job will end up with a success．Not every dream will come true．But when you can't achieve your goal，maybe you can say，"Yes，but look what I've found along the way!There are so many wonderful things that have come into my life because I tried to do something!It is in the digging that life is livedis the unexpected joy on the journey that really has a meaning．

12．At present，too much carbon dioxide（二氧化碳） makes the earth warmer and causes terrible effect to human beings．To save our planet，to save ourselves，a new lifestyle called low-carbon life（低碳生活） becomes popular．Low carbon means low energy and no waste．It is necessary for everybody to learn to live a low-carbon life．
To live a low-carbon life，we'd better save energy as much as possible．Turn off the lights and TV whenever they are not needed．If possible，use cold water to wash clothes or dishes．Take a short shower and try to take a cold one when the weather gets warm．Don't do the cooking with electricity．
To live a low-carbon life，we should eat less meat．Everybody knows eating too much meat makes people fat and easy to have heart disease，but maybe you don't know keeping animals for food produces even more carbon dioxide than all the cars in the world，and being a vegetarian can help reduce（减少） one and a half ton（吨） of carbon dioxide a year．Maybe it is a little difficult，but it's really necessary．
To live a low-carbon life，we are supposed to do less shopping．When we go shopping，we may drive a car or take other transportations．On the one hand，these machines pollute the air and waste energy．On the other hand，most of us always buy some useless things because of some advertisements．It is not only a waste of money but also causes trouble to the earth，because as you know，making everything will produce carbon dioxide more or less．
There are many other ways  to live a low-carbon life，such as recycling things，planting trees and reusing textbooks．If we can keep it a habit in our daily life，the earth will become a safer planet for us to live on．

2Since January，many cities in China have seen a lot of foggy days．During these days，people can only see things that are very near them．In Beijing，only five days in January were free of smog．what's the difference between fog and smog？
3According to scientist，fog is made up of tiny（微小的）drops of water and also ice particles（颗粒）during very cold conditions．Smog is dirty air that looks like a mixture of smoke and fog，caused mainly by smoke from cars and factories in cities．
4An offical for the minnistry of environmental protection told Beijing News that PM2.5pollution is the main problem with air pollution．Pm2.5refers to pollution with small particles 2.5mircrometers or less in diameter（直径）．
5According to the Chinese Academy of Sciences，motor vehicles and burning coal are two major factors for PM2.5．
6Poor air is bad for people's health，especially for Children's．Hospital shows that from January 5th to January 11th，half of the patients in the internal medicine department（内科门诊） are there for breathing problems．
7the problem and environmental protection have become a care for the whole nation．Li Keqiang made his last Government Work Report on March 6，2014．The report said that the government should work hard to prevent pollution and give people a healthy living environment．
It calls on people to make full use of energy and resources and cut down on energy use．"we should give people hope through our actions'Li said．

14．FIFTEEN YEAR-OLD  Liu Xuyang said he has more than 30 pairs of shoes．But some are old．He doesn't want them any more．
Where should these old shoes go？To the garbage or to be recycled？
This is bow Liu began to care about old shoes．He shared his thoughts with his classmates at Beijing No.35 Middle School，Luo Hao and Yang Mengwei．The three then decided to do some research．They found out that old shoes can pollute the environment if not recycled properly．Earlier this month，their research paper won second prize in the Beijing Youth Science and Invention Competition．
The three first spent two weeks designing a questionnaire on how people deal with old shoes and how the shoes are treated．They gave over 100 questionnaires to the public，to shoemakers，garbage stations and recycling stations．
Doing the survey，they found that on average（平均），a family throws away 5.17 pairs of shoes each year．That means millions of old shoes are thrown away a year around the country．
However，most old shoes are not treated properly，according to the students．
"Usually．the old shoes are just burnt or buried（填埋）with other garbage，"said Luo．
Most of the shoes are made of chemical materials．If they are burnt or buried，they can give off gas（气）or other things that pollute the air and rivers，said the students．
They suggest there should be big boxes in cities for people to put old shoes in．The shoes could then be taken to recycling stations to be treated．
On the other hand，the shoemakers，said the students，could use more environment-friendly material to make shoes．

C．has more than thirty classmates in his class

11．The Little ants is a special shadow puppetry performing troupe（皮影戏演出团）．Its members'average（平均的） height（身高） is 1.28 metres．Li Ming created The Little Ants in 2009．He said he started the troupe to help little people like himself who had difficulty finding other jobs．
Li's team now has about twenty members．Like most of the members，Yang Suxuan found about The Little Ants on the internet．The village girl contacted（联系） Li Ming and decided to join the troupe，which now she calls home．
"In the past，I didn't want to communicate with others．I always felt they would laugh at me，"she recalled．"Now all my family members told me I've changed．I don't know how，but I am really glad that I found a job that can support myself．"
At first Yang and her workmates took the job only for a living．But gradually they have also come to understand the importance and responsibility of their job-to keep an old folk art（民间艺术）alive．
Shadow puppetry was widely popular in the past，      later people gradually lost interest in it．Promoting（推广） folk art in a modern city is not an easy job．Several times，the troupe had no money to pay the staff．In 2011，shadow puppetry was listed as a world-class cultural heritage（世界文化遗产）．Since then，the situation for The Little Ants has got much better，and Li's small business has become successful．
"My dream is to continue promoting shadow puppetry and providing more jobs to little people，"Li said．"I hope more people will understand shadow puppetry through us，and know that we little people are able to do something great too．"
