School homework and use of electronic devices（电子仪器）are main causes， a report says． More than 60% of children and teens do not get adequatesleep， which can put their health at risk， according to a report that came out on Sunday by the Chinese Sleep Research Society． The report was from a survey at the end of last year and in January． It covered nearly 70，000 children and teens aged 6 to 17 across the Chinese mainland， Hong Kong， Macao and Taiwan．
The report found that the heavy school homework load（负荷）and the popularization of electronic devices were the two top causes for the inadequate sleep． From Monday to Thursday， 8． 4% of the group would still be busy with their homework after 11 p． m． More than 41% of children and teenagers who sleep too little use electronic devices， and children whose parents use smartphones in front of them are more probably to have less sleep． Other reasons， such as noise and light pollution， made the problem happen， the report said． The survey also showed that good sleep results in higher efficiency（效率）in study．
Gao Xuemei，vice﹣president of the society， said studies have shown that decreasing（减少）sleeping time for children and teenagers has been a global trend（全球趋势）in the past 10 years，but the problem appears to be worse in East Asia， including China， largely because of a heavier load of school homework．
"Lack（缺失）of sleep among children and teenagers is worth paying high attention to，because it can seriously affect their health and growth，" she said． "Such a group should sleep at least eight hours a day，" she added． "Sleep develops growth， protects the brain and improves the immune system（免疫系统），" she said． "Long﹣term lack of sleep will bring risks of diseases（疾病）and conditions such as dementia（痴呆）and cause lasting health harm．"

A kind of little cars may be seen in the streets in the future. People will like this kind of small cars better than the big ones. The car is as small as a bike. But it can carry two people in it. Everybody can drive it easily, just like riding a bike. Even children and old people can drive them to schools or parks.
If everyone drives such cars in the future, there will be less pollution in the air. There will be more space for all the cars in cities, and there will also be more space for people to walk in the streets.
The little cars of the future will cost less money to buy and to drive. These little cars can go only 65 kilometers an hour, so driving will be safer. The cars of the future will be fine for going around the city, but they will not be useful for a long trip.
This kind of cars can save a lot of gas. They will go 450 kilometers, then they have to stop for more gas.
They are nice cars, aren’t they? If you drive this kind of little cars for four hours, you can probably go at most.

Li Tao，a Junior 1 student，was quite busy over the past winter vacation but not just with homework.Li，together with his 10 classmates made a volunteer group to call on people to join in The "Clean Your Plate Campaign" （光盘行动） .
The 11 students went to many restaurants and told people the importance of saving food. "Excuse me，do you know that 950 million people around the world still haven't got enough to eat？Please don't waste food." They would say that hundreds of times every day.
China in these years has serious problems with wasted food.CCTV reports that the food Chinese people waste every year is enough to feed 200 million people for a year.
Chinese people are well ﹣ known for being generous （慷慨的）.Many even feel that they lose face if their guests have eaten all the food.
To reduce food waste is a big task，and it needs time.It's important that everyone should do their bit，just like Li.Did you finish your meals today？
Judge the following statements True（T） or False（F）.
（1）Li Tao was only busy with his homework over the past winter vacation.
（2）The 11 students went to the same restaurant and said the same words many times.
（3）The problems with wasted food in China are serious.

How do you remember the way to your house? Where do dreams come from? It is your brain(大脑) that does these things. A British scientist showed that “sleep can improve one’s memory.” It’s not a dream for students to study when they sleep. In fact, your brains is working day and night. If you learn words before bed, a certain part of the brain may help you to remember the words while you sleep. What’s more, another scientist in the USA found that there was a “talent button(天才按钮)” in the human brain. It might make a person more talented.
There are more interesting things about the brain. Your brain uses less energy than a fridge light. Just two bananas can give the brain enough energy to work for a whole day. According to some scientists, yawning(打哈欠) keeps our brains “cool”, which makes us think quicker.
Here are some pieces of advice to keep a good brain:
Eat healthy food.
Get a lot of playtime or exercise.
Don’t drink or smoke.
Use your brain a lot. A British scientist found out that ________ could improve our memories.
| A．drink | B．dreams | C．sleep | D．bananas |
According to the passage, if we want to have a good brain, we should ________.
| A．use our brains more | B．sleep fewer hours |
| C．work longer hours | D．remember fewer things |
Which of the following is TRUE according to the passage?

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!

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 |
4 |
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.
（1）What's the latest tool a dog might have in the fight against cancer？

Eight years ago， 1﹣week﹣old Diandian was left behind． When people found her in the reeds （芦苇） of a lake， she looked too weak to survive． Now she is the mother of three milu， thanks to the workers' attention and care at the East Dongting Lake National Nature Reserve．
Li is the president of a milu conservation association in Yueyang and head of a local milu and bird rescue center， where 11 deer， including Diandian， have their families． Li and his workmates need to work extra hours to take care of the animals from March until mid﹣May． He remembers March 18 this year． He fed Diandian some fresh shoots and leaves for breakfast as usual， and moments later when he returned，a newborn milu was right beside her． Since it is her third baby and born in the third month of the year，people named it Sansan， referring to "three﹣three"． Li has developed a deep affection for milu and made up his mind to protect them． "As our country is paying more attention to environmental and wildlife protection， people are increasingly aware that milu are state﹣protected animalsm，" Li said．
Milu habitats （栖息地） are usually centered around water， and fishing equipment that used to be a threat to the animals is no longer seen in nature reserves． On May 27， a team of experts went to watch milu near Dongting Lake． It takes time and luck to meet one and count them especially when they live in the thick reeds that are 4 to 5 meters tall． The team leader Song， saw a milu for the first time when he was studying for his doctorate in zoology early in 2009． Since then， he has helped protect the habitats at Dongting Lake． As the flood season is coming， Song and his workmates will go around the lake area day and night to save deer in trouble， and provide feed for the animals when needed．
As the environment improves in and around Dongting Lake， China's second﹣largest freshwater lake， the wetland has become cover once again for wildlife． "We will continue to protect these rare animals and their living environment，" Song said．

You don' t have to be a scientist to solve big environmental problems． One Dutch designer is finding creative ways to make a change﹣and he's inviting bikers to join him．
Daan Roosgaarde， 38， is a designer from Holland． He uses creative ideas to improve city life． For his Smog （雾霾） Free Project， he designed a special tower that cleans air in Chinese parks． In Holland， he designed a shining bicycle path．
Now Daan and his team are working with engineers at Chinese bike﹣sharing company Ofo to create a new product for public use． It's an air﹣cleaning machine connected to a bicycle and is part of the Smog Free Project． In smoggy weather， the machine would breathe in the air in front of the bike and blow out a stream of clean air toward the biker's face．
It's no secret that air pollution is a big problem for China． In winter， it's common for thick clouds of haze （霾）， caused largely by factory production， burning of coal and car emissions （排放物）， to cover areas of China．
In 2016， only one﹣fourth of Chinese cities met the country's air quality standards， according to a survey of 338 cities nationwide from the Ministry of Environmental Protection．
"Of course one tower and a few bikes won't solve China's air pollution problem，" Daan said， "But smog﹣free bikes are an exciting idea that will hopefully inspire communities to create greener cities．"
