All of us should keep a kitchen diary， and we can know how much food we waste at home． The first thing for us to do is stop throwing away food that we can still eat．We should eat everything we buy and if we cannot， we should buy less．
♦ Buy only what we need
We should ask for smaller ones in the supermarket． We should also check how much food we have ①______ buying more． We shouldn't bring much food we don't need home even if large posters ask us to do so．
♦ Develop the habit of ②______ food
Chinese customers are generous（慷慨的）and friendly． In restaurants， often too much food is ordered and served． So when eating out，we are supposed to exclude（排除）the food in the menu if we don't plan to eat it． And order smaller servings in restaurants and take home what we cannot finish．
Don't put it off! Let's stop food waste today!

Sleep plays an important role in brain（大脑）development．Children should get enough sleep．（1） A study says that because of being short of sleep，it is much harder for children to do something carefully．And also they become forgetful and easy to make mistakes．Another study shows that the right amount of night﹣time sleep is just as important for children's development as healthy eating and taking exercise．
（2） In general a younger child needs more sleep than an older one．Children at the age of 5﹣11 will need 10﹣12 hours of sleep a night while children at the age of more than 11 will need less hours
In fact，many parents don't know how to help their children get enough sleep．Here is something you can do．For children at the age of 5﹣11，a 30﹣40 minutes routine（常规）before sleep is helpful．（3） In the activities，children relax and enjoy themselves a lot，and they will go to sleep more easily．
Children at the age of more than 11 may go to bed late in the evening，talking with friends online，playing games or watching TV．（4） And even they will be tired during the day．So limit（限制）your children's use of the Internet，games and the TV before they go to bed．（5） ．

Around the world，there are about 7，000 National Parks．Most of them cover huge areas of land where nobody lives．However，the National Parks in England include places where people live and work，as well as wild areas where there are few human activities．
The National Parks in England are called"England's Breathing Spaces"because they are places where people can go to be in the open air，away from the dirt and noise of cities．They provide wonderful scenes of mountains，woods，grasslands and wetlands．And there are plenty of activities to do in all of the National Parks in England．Visitors can walk or ride bikes for fun．Many of the parks put on activities for families．
Every year there are about 110 million visitors to the parks，bringing many benefits（益处） to the
areas．At the same time，it creates problems too．First，life can be difficult for local people．Car parks and roads are too crowded．Gift shops and cafes take the place of many everyday shops．Even house prices in some areas can become too high．Besides，country roads can be damaged，for too many people walk，cycle or ride horses on them．Roads can be rebuilt，but then they look less natural．Another big problem to the National Parks is litter．In the parks it is a danger to wild animals．Broken glass can also cause fires by focusing the rays of the sun．Such fires in wild places can be out of control．All National Parks in England are making more rules，which tell people how to take good care of their environment．If these rules are followed，the National Parks will be well kept and continue to give pleasure to
many people for a very long time．

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.
（1）Is it an easy job for Wang Chengbang to plant trees？
（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.

Wash your hands． You need to wash your hands with soap and water before you eat， after you use the toilet， and after you touch animals， because your hands may carry viruses （病毒）．Cover your nose and mouth． When someone sneezes（打喷嚏）or coughs，the viruses can travel as far as one meter through the air，so you'd better stand a proper distance while talking to someone who has a cold． And always cover your mouth and nose with a piece of paper when you sneeze or cough，and then clean your hands． Wear a mask（口罩）． Some doctors say that masks can stop the virus as much as 80%， but if you don't wash your hands often， it's no use wearing a mask． So it's necessary to wear the mask in the groups of people．
Do sports often． Exercises will help make your body strong enough to resist（抵抗）the virus．
