October 16 is World Food Day． The UN started the day in 1979． Itis used to remind people not to waste food and to ask people to fight hunger（饥饿）．
A big member of people in the world still don't have enough to eat. Food shortage（匮乏） is a big problem in the world．Right now， there are more than 1000 million hungry people in the world according to the UN．Many children go to sleep， hungry and 15 million of them die of hunger each year．
There are several reasons why there are food shortages．First，there have been more droughts（干旱）and floods recently． Also， a growing population makes feeding everyone more difficult．
Another several reasons is food waste . Most people don't realize how much food they throw away every day． On avenge （平均），person throws away 50 kilos of food every year. According to the UN，more than 1/3 of all food produced in the word goes to waste each year． The amount （数量）of food wasted in Europe can feed 200 million people and the food wasted in Lain America can feed 300 million a year．
So think twice next time you want to throw away food． If you try to avoid wasting food， you could save some food and help hungry children. Only order as much food as you can eat at a restaurant. If you can't eat all you order， take the rest home．Don't be too picky about food so that you don't leave any on your plate . Keep eye on what food you have at home． Don't buy or cook too much．

How to Get Children to Stop Touching Their Faces
Kids seem like they're always touching everything in their environment， from tables and chairs to doors and stairs． Since those surfaces may hold germs（细菌），you can help your child avoid illness by encouraging them not to touch their face throughout the day．
（1） Once your child is about 3 years old， you can begin having conversations with them about avoiding germs， including the importance of washing their hands and how touching their face can spread germs to their nose and mouth． While just knowing this information probably won't help them break the habit， it can help set the groundwork．
（2） If you don't want to criticize（批评） your child when they forget， it is important to remind them when you see them with their hands around their face or mouth． Sometimes， just knowing that they 're doing it will be enough to help them stop doing it．
（3） It can be hard to remember sometimes， but look for chances to let your child know when they're doing a good job of keeping their hands away from their face． Encouraging words can be a really powerful motivation（动机） for kids to keep trying when they 're learning something new．
（4） Children often touch their faces or mouths without thinking about it． Many times， it's just because they're bored and they're looking for a way to excite themselves． If you think that might be the case， try giving your child a toy they can hold onto．
A． Point out any time you see your child touching their face． B． Encourage your child to wash their face carefully． C． Offer your child something they can hold． D． Explain why it's important if your child is old enough． E． Praise your child when they aren't touching their face． |
（5）The passage is most probably chosen from the part of in a newspaper．

Want to make a difference in your community？ Becoming a zero waste volunteer is the way to go!
Join a community garden
So many people don't know where their food comes from． Growing food by yourselves teaches you the true value of food． What's more， there is no need to pack the food you grow in the garden． Offer your time to help support a garden in your neighborhood． You'll get to meet all kinds of people there， and possibly begin a conversation about zero waste lifestyle．
Lead or join a neighborhood clean﹣up
Usually， litter left unattended （无人看管的） will pollute our water systems． Even worse， any litter （in the ocean or on the ground） can be eaten by animals． This causes them to die of hunger slowly and painfully． Getting a group together to pick up trash （垃圾） around the neighborhood is a great way to combatthis problem．
______
Going to a town hall meeting is a great idea． Because you can see and hear the problems in your community． Besides， you may even be able to speak at a town hall meeting as a guest speaker telling other people about zero waste lifestyle．
Organize a zero waste meeting
It's so important to have a support group filled with people who also love zero waste lifestyle． Although online community is great， it cannot compare to real life support groups． If you want to gather people in your neighborhood to talk all things about zero waste， consider organizing a meeting． Just choose a place to meet （a local cafe works well）， choose a date and time， and put up a notice on the Internet． You'll get surprises!
（1）If a person joins a community garden， he or she can ．

We should not use more water than we actually need． If we do， we will not have enough water in the future． （1） It is not a difficult question to answer． If we remove more fresh water than nature replaces， we have taken too much．
Many cities run campaigns（运动）to get people to stop wasting water． They show them ways they can cut back on water use． （2） What's more， they carry out programs that offer money to reduce water use． For example， they give people shower heads and toilets that use less water． （3）
Another threat（威胁）to our water supply is pollution． When our sources of fresh water get polluted， we can no longer use this water． This also endangers（危及） the animals that depend on the water．
（4） We can save lots of water by not letting taps（水龙头） run while we brush our teeth or by turning off taps right after washing hands． By collecting cold water when were taking warm showers， we can also save water． （5） In this way， we can make full use of water．

New Way to Recycle
When Shanghai introduced a new garbage﹣sorting policy in July last year，the city's residents（居民）took some time to get used to it．They joked that every time they took out their garbage，the staff（工作人员）standing by the bins would ask "What kind of garbage are you？"
Starting on May 1， Beijing joined many Chinese cities by introducing a new garbage﹣ sorting policy， People's Daily reported． Residents should sort their garbage into four groups kitchen， recyclable， hazardous（有害的）and other waste．
These groups are represented（代表）by four different colors of trash bins﹣green，blue，red and grey．Those who fail to sort their trash correctly may face fines of up to 200 yuan， Xinhua reported．
The way Beijing sorts its trash sounds different from others like Shanghai and Qingdao． These cities use for different groups： wet， recyclable， harmful and dry． Although their names are different， the groups are actually the same． Wet garbage in Shanghai is， in fact， kitchen garbage． And dry garbage is the same as other waste． China Daily reported．
To help residents sort their trash correctly，the Beijing government is offering online guidelines．If people don't know how to throw away garbage，they can search for it on the WeChat account Guanchenglish（管城理事） to find out． By searching a key word or taking a photo， people can immediately find out which group their waste belongs to．

What do you do with your rubbish？Throw it out？You don't know what you're missing!Look closely at the two figures on your left.They were made from things most people throw away.The figures were made from used bottle caps.Those two bottle﹣cap figures were exhibited （展示） in a museum.
Folk art is art made by common people who have not been trained as artists.Their work is often based on traditions in their culture.Fine art，on the other hand，is usually made by people who have had training in art.Works of fine art are valued for their artistic beauty.They are supposed to be looked at but not used.Works of folk art，however，are often made for everyday use.
There were more than 800 pieces of folk art from nearly 50 countries in the exhibition.All of the pieces were made from used metal，wood，cloth，and plastic.The artists come from many different cultures.Still，they all share one thing.They take objects that are normally thrown away and change them into objects that are beautiful，useful，and fun.The artists may not think of what they do as recycling，but that's exactly what it is.Fine artists might work with expensive materials.They might use expensive tools to shape these materials into works of art.On the other hand，in poor countries rubbish might be the only material folk artists and toy makers can afford.The exhibition shows that a rich imagination is very important when there are only poor materials.Recycled art began long before people began to think about recycling.Some of the objects in the exhibition date from the 1930s.
Even if you don't create art out of rubbish，it's good to save our natural resources.Remember the three rules：reduce，reuse，recycle.If you reduce waste，true things instead of throwing them out，and recycle materials such as paper，plastic，and glass，you will protect the environment.

How would you feel if someone decided to take away your park？ Well that's what's happening in my community． There's a park that some people want to turn into a golf course（高尔夫球场）．Let me tell you why I think it's a bad idea．
First， a park is meant to be for the whole community． Not everyone likes golf， so not everyone will get to use the park． This isn't fair． A community park should have open spaces for everyone to use．
Second， to make way for the golf course，lots of playground equipment（设施）will have to be moved or knocked down， which is a waste of time and money．It's also a waste of perfectly good equipment，The swings， for example， will probably just end up as litter．
Third， what about giving young people something to do？Not all kids are crazy about golf．At the moment， the park has a skating place and a playground． These attract lots of kids from the community． If you turn the park into a golf course， these kids won't have anywhere to go and they won't have anything to do．This means that they will stay at home and turn on a video game rather than get some exercise． It also means that they might be out on the street causing trouble．Wouldn't it be better to give them something to do at the park？
Finally，golf is expensive．Building a golf course and maintaining（维护） it costs a lot of money．Who is going to pay to maintain the golf course？ What about those people who can't afford to join a golf club？That means that the golf course will only be available to people with lots of money．
Turning our park into a golf course is a bad idea．I suggest we have a community meeting before plans go any further．
（1）Some people want to change the park into ．
A． a golf club
B． a golf course
C． a parking place
D． a skating place
（2）According to Paragraph 4， having nowhere to go will make some children ．

B． fall in love with golf
C． play video games at home
D． go to the street and make friends
（3）Which of the following shows the structure of the passage？
（P＝ Paragraph）
（4）What is the writer's purpose in writing this passage？

D． To stop the golf course from being built．
In 1988，Wang Chengbang retired（退休）from the army.Instead of enjoying a relaxing life，he volunteered to save the soil from desertification（沙漠化）by planting trees in Korla，Xinjiang.
It is no easy job.The high temperature in Korla makes it difficult for anyone to work day after day in the sunshine.Besides，water is a big problem.In fact，Wang Chengbang's work in the first few years failed as very few trees survived（存活）.
But Wang Chengbang would not give up."After trying many different ways，I have learned how to grow young trees in a better way，" said Wang Chengbang.He also worked out new ways to save water.With his hard work，more and more trees have survived.So far，he has planted more than 1.5 million trees.Those green trees prevent desertification，make the air cleaner and protect people from the hot sun.Now，Korla is a model city in environmental protection.
Wang Chengbang is also successful in fighting cancer（癌症）.In 2005，he had cancer and was told that he had only six months to live.However，he continued taking care of his trees rather than lying on the hospital bed."Working is the best medicine.Planting trees helps to fight cancer，" he often jokes.
Now，at the age of 85，Wang Chengbang is still working.

（2）How many trees has Wang Chengbang planted so far？
（3）What is Wang Chengbang successful in？

Do video games do harm to our children？Today，many children spend a lot of their free time playing games on the Internet.In the UK，99%of kids aged8 to 15 play video games every week.This information tells us that the benefits and dangers of video games must be carefully considered.
For many people，video games are fun.They have bright lights，funny cartoons and exciting stories.Everywhere you look，you can see children playing these games.They play on buses and trains，in restaurants and even at school.
Video games are educational too.They make kids think in a creative way and theyhave to move their hands and eyes quickly.This can improve the way that a child's brain works.What's more，video games make children use their imagination.The player has to do many creative things，like drawing，telling stories and building things.Video games are also a good way to teach children about technology because they can learn how computers and other devices work while they play.
However，a recent study suggests that video games can also be bad for children.First，children can download many games for free.This means that parents often don't know if their children are playing violent or scary games.Second，many children spend too much time playing games on computers and this can lead to health problems.Third，if children spend too much time playing games instead of doing homework，they can have problems at school and get bad grades.Finally，video games can affect children's social skills.If children spend too much time playing video games by themselves，they might not learn how to play with their friends.
In conclusion，it seems clear that video games have some advantages and some disadvantages.It is up to parents to know what games their children are playing and how much time they spend on them.Parents should also make sure their children get enough exercise and spend time with other children.

Dogs might have the latest tools in the fight against cancer （癌症）：their noses!Researchers at California's Pine Street Foundation （PSF） say they have trained five dogs to smell cancer on a prison's breath.This could be exciting news.
A dog's sense of smell may be 10，000 to 100，000 times stronger than ours.But can dogs really smell illness？PSF researcher Michael McCulloch says yes. "We were very surprised by how exact they were，" he said. "They were telling who had cancer，and they were also saying who didn't."
McCulloch and his team asked four healthy people and one with cancer to blow into plastic tubes （塑料管）.Special materials in the tubes kept the things of each breath.The tubes were then placed one yard apart.Finally the dogs were allowed to smell the tubes.Each dog had been trained for three weeks to sit when it smelled cancer.Ninety﹣nine percent of the time，the dog sat next to the tubes blown into by patients with lung cancer.The dogs were right 88 percent of the time about breast cancer.
| Dogs in the Pine Street Foundation test were trained to sit when they smelled cancer.How well did they perform？Take a look at this chart to find out. |

| Breath Sample |
Number of Times the Dogs Sat Down |
Number of Times the Dogs Kept Standing |
| Breath from lung cancer patients |
564 |
10 |
| Breath from healthy persons |

720 |
No lab test for cancer has given more correct results than this test.The results are so amazing that many experts question the dogs' smelling power.They wonder if there were other reasons why the dogs did so well.For example，they thought the way the dog trainers behaved could have influenced how the dogs acted.However，most experts agree that this study is important.The information could help scientists create a simple breath test for cancer in the future.Once again humans may be getting a helping paw or nose﹣from their best animal friends.

The world uses about a thousand million （百万） tons of water a day． Water is a human right and everyone should have their share． Yet more than 700 million people around the world have trouble getting clean， safe water．
Treating wastewater is a good way to provide fresh water for us． And it also helps the environment by keeping waste out of rivers and oceans． 80% of wastewater around the world is not treated at all， and it is running into oceans．
But now we have got the technology to treat and reuse the wastewater．
