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．"

Electronic books have changed the way many people read for 15 . Now online textbooks are changing the way some students learn and some teachers teach.
More than 16 students go to the public schools in Fairfax County, Virginia, outside Washington. Last year, the school system used digital books in fifteen schools. This school year, middle schools and high schools changed 17 printed to electronic textbooks in their social studies classes.
“I mean, it’s just 18 a regular textbook, except it’s got it all online.” says Luke Rosa, a history teacher at Falls Church High School.
Peter Noonan, an assistant superintendent(主管) of schools says, “The world’s changing 19 . And the online textbooks can change right along with the events that 20 .”
“Digital books also cost 21 than printed textbooks,” he says, “Usually it’s between fifty and seventy dollars 22 a textbook for each student, which adds up to about eight million dollars for all of our students in Fairfax County. In fact, we have bought all of the online textbooks for our students for just under six million dollars.”
Social studies teacher Michael Bambara says the e-book he uses in his government class is better than a(an) 23 textbook. It has materials for students 24 different levels of reading skills…

Look closely at your hands. Are they clean? It doesn't matter how many times you wash your hands, tiny microbes (微生物) still stay on them. But don't worry. Most microbes don't harm you.
Now scientists say the microbes on our hands cou
ld be used in a surprising way; fighting crime, According to a recent survey microbes as well as fingerprints(指纹) could be used to indentify the criminal.
Everyone has his own set of microbes on the hands. That is to say, if you and your best friend were able to see and compare all the microbes on your hands, your hands probably would look different. Some microbes only show up on your hands while others live only on your friend's hands.
When you work on a computer you leave the microbes from your hands on the keyboard. The scientists can easily tell the owner of the keyboard by looking at the microbes on it. Even if you don't leave your fingerprints behind, your microbes may give you away.
Noah Fierer, a scientist, says. "You can only clean a fingerprint, but you can't sterilize (使无菌
) a surface j
ust by wiping(擦) it off," He says that scientists have a lot more work to do before the microbe is used as a useful tool.According to the passage,_______ could be used to identify the criminal.

The world itself is becoming much smaller by using modern traffic and morden communication means （工具）． Life today is much easier than it was hundreds of years ago， but it has brought new problems． One of the biggest problems is pollution． To pollute means to make things dirty． Pollution comes in many ways． We see it， smell it， drink it and even heart it．
Man has been polluting the earth． The more people have， the more pollution becomes． Many years ago， the problem was nor so serious because there were not so many people． When the land was used up or the river was dirty in one place， man moved to another place．But this is no longer true．
Man is now slowly polluting the whole world．
Air pollution is still the most serious． It's bad for all living things in the world， but it is not the only one kind of pollution， Water pollution kills our fish and pollutes our drinking water． Noise pollution makes us angry more easily．
Many countries are making rules to fight pollution． They stop people from burning coal in houses and factories in the city， and from putting dirty smoke into the air． Pollution by sulfur dioxide （So2） is now the most dangerous kind of air pollution， I! is caused by heavy traffic． We are sure that if there are fewer people driving， there will be less air pollution．
The earth is our home． We must take care of it． That means keeping the land， water and air clean． And we must pay attention to the rise in pollution at the same time．

Waste sorting（垃圾分类） is a big matter worldwide． In order to sort the rubbish properly and protect the environment， people in different countries are using different methods to sort their waste．
UK A UK company invented a "smart bin" to help with waste sorting． People just need to drop their waste into the bin（垃圾箱）． A camera and sensors（感应器） in the bin can tell what type of rubbish it is and correctly sort it． The bin also compresses（压缩） the waste so it takes up less space．
South Korea South Korea is using a method called "Pay For Your Waste" to encourage its people to reduce food waste． When throwing away rubbish， people have to separate their food waste from their other rubbish and put it in a bin． The smart bin then weighs the food． People have to pay for their food waste by scanning（扫描） a barcode（条形码） on the bin． If they throw away more rubbish， they will pay more．
Japan Japan is leading the world in waste sorting． They sort waste so carefully that even plastic bottles and their caps go into different bins． Different types of paper products have their own bins．
China China is improving its waste sorting efforts． Shanghai has worked with Alipay to create a "green account（账户）"service for its residents（居民）． The city is asking all of its residents to sort their waste into four groups： wet， recyclable， harmful and dry．

It's reported that more than 450 million Chinese have myopia（近视）． Around 30 percent for primary school students， 60 percent for junior high students and 80 percent for senior high students are nearsighted． Maybe this is because students spend a lot of time reading books and using electronic products．
Parents might have tried to do something to fix it， such as having their children get eye massages（按摩）， take medicine or even get surgery． People who offer these services or products often promise that they can reduce（缓解） or even cure（治愈） myopia．
However， you will no longer see advertisements like this before long． The government has made a notice to ban（禁止） this kind of advertisements． The notice bans businesses from using words like "recovery"（恢复） and "myopia cure" in their advertisements． The notice says that myopia cannot be completely cured with medical technology now． As a result， these advertisements could mislead children and their parents．
To reduce myopia among young people， the government made a new plan last August． The plan limits（限制） not only the time children play video games but also the production of new video games．

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？
A.Tooth.
B.Nose.
C.Ear.
