When Oakland High School in California moved into a new building, the students and teachers noticed a strong smell. Then almost half of the students began to have a headache and a cough. Experts (专家) came to find the cause of the sickness. Finally, they discovered that the air in the building was not safe to breathe. They were surprised to find out that the desks and chairs in the school library caused the trouble. These desks and chairs were made of particleboards(合成板). This kind of board is cheap. It is made of very small pieces of wood held together with a chemical (化学物质). This is just one example of a modern problem that is most common in cities—indoor air pollution(污染).
People have worried about air pollution for many years, and the government has spent lots of money trying to clean up the air of big cities. But now we found that we are still breathing unhealthy air. A study shows: Indoor air pollution is almost two to five time(倍) worse than outside pollution. So remember to open the windows and don’t stay too long in modern buildings with windows closed. Many students and teachers _________ after they moved into the new building.
A were very happy and excited B. didn’t feel well C. felt tired because of hard work The experts came to Oakland High School for _________.

C. finding the cause of the illness Which of the following is Not true according to the passage?
A. The indoor air pollution is common in cities.
B. We needn’t worry about the outside pollution.
C. The air in this school library was not safe to breathe. A study shows that indoor air pollution is _________.
A even worse than the outside pollution B. not so bad as outside pollution

Paying for bus rides with plastic usually makes people think of plastic bus cards．But one Indonesian city has decided to accept plastic recyclable waste in place of money for city buses．
Surabaya， Indonesia's second largest city， located on the eastern end of the country′s main island Java， made this decision in April 2018．Now，locals can pay for their bus rides by putting plastic cups or bottles directly on the bus．A two﹣hour bus ride costs 10 plastic cups or 5 bottles．
Indonesia is the second largest ocean plastic polluter， producing up to 2.4 million tons of plastic waste into the oceans every year according to a report．Only in Surabaya nearly 400 tons of plastic waste is produced every day．The head of Surabaya's transportation department（交通部门） said，"With this decision， we hope to raise public awareness about environment， especially people's awareness about plastic waste．"
Each city bus can collect up to 550 pounds of plastic bottles and cups every day．The collected bottles are sold to recycling companies and the money earned from it goes toward running the bus companies and providing money for green spaces in the city．This is certainly turning rubbish into a national treasure．
The decision is part of the city's purpose to become plastic waste﹣free by 2020．In order to encourage local people to take buses，the city also added the new Suroboyo buses．The new buses are air﹣conditioned，comfortable and easy for elderly and disabled passengers to get on and off．
The program is well received．People in Surabaya said，"We can reduce waste so it doesn't pile up at home because we can just bring it in and make good use of it． It is a win﹣win situation．"
This type of program can be a model for other cities worldwide and encourage citizens to recycle their plastic waste．
回答下面5个问题，每题答案不超过六个词．
（1）Instead of money， how can locals in Surabaya pay for bus rides now？
（2）How much plastic waste does a two﹣hour bus ride cost？
（3）How much plastic waste is produced in Surabaya every day？
（4）What is the purpose of the new program？
（5）What do local people think of the new program？
In Chicago, a computerized system has been developed that controls(管理)traffic on the city’s 235 miles of seven expressways. Now one—a controller—can follow the movement of Chicago’s traffic by looking at a set of lights. The system uses electric sensors(感应器) that are built into each expressway, every half a mile. Several times a second, the computer receives information from each sensor and translates it into green, yellow or red lights on a map in the control room. A green light means traffic is moving forty-five miles an hour, yellow means thirty to forty-five miles an hour, and red means heavy traffic—cars standing still or moving less than thirty miles an hour.
“See that red light near Austin Avenue?”the controller asked a visitor.“That’s a repair truck fixing the road, and the traffic has to go around it.”At the Roosevelt Road entrance to the expressway, the light kept changing from green to red and back to green again.“A lot of trucks get on the expressway there,”the controller explained.“They can’t speed up as fast as cars.”The sensors show immediately where an accident or a stopped car is blocking the tr
affic, and a truck is sent by radio to clear the road. The system has lowered the number of accidents by 18 percent. There are now 1.4 deaths on Chicago’s expressway for each one hundred million miles traveled, while in other parts of the county there are 2.6.
Traffic experts say that the Chicago system is the “coming thing”.Systems like Chicago’s are already in use on some expressways in Los Angeles and Houston.“Chicago has taken the lead,”said New York City’s traffic director and he added,“Chicago’s a good example.”

A new report from a university says 80% of the world's teens don't get enough exercise every day， The report was based on （基于） a research done with about 2 million students aged 11 to 17 around the world．According to the report ， activity standards are different in different countries and they are also different between boys and girls． In China， for example， only 20% of the boys are active enough， compared to 11% of the girls．
Why don't teens go out for exercise？ One main reason is that they always have technology products in their hands or around them． They spend too much time on smartphones，computers and TVs in their free time． Many teens find it very hard to pull themselves away from these devices （设备）．The report says that young people need to do less in the digital world but more in the real world． It advises kids to get at least an hour of exercise every day． This could include running， biking， playing sports， or many other outdoor activities．
More and more research shows that exercise not only helps the body， but also helps the brain．Besides， doing sports helps kids to make friends． Mark， a sports fan， started to play football when he was six years old． He used to be shy and weak， but now he has become taller and stronger．He gets to know the importance of communicating with his teammates and how to learn from mistakes and failure．And he has made lots of friends with the same interest． They often have football training on the playground． They have more to talk about and enjoy the happiness after training．
根据短文内容，回答下列问题．
（1）How many students around the world took part in the research？
（2）Are activity standards the same between boys and girls according to the report？
（3）What does the report advise kids to do？
（4）When did Mark start to play football？
（5）Where do Mark and his teammates often have football training？
In our daily life， much plastic package is used just once and then thrown away． According to a new study from the University of California， 9% of this is recycled， 12% is burnt and 79% goes to landfill． And because most plastic doesn't biodegrade， once it's in the ground， it stays there． （1）The study also shows that eight million tons of plastic waste are pouring into the sea every year．
Scientists have calculated the total amount of plastic ever made： 8.3 billion tons． That's as heavy as one billion elephants． And almost all of it has been made in the last 65 years．
（2）每个人都应该参与拯救地球． Protecting the environment is protecting ourselves． If the environment is taken good care of， we can have clean water and green mountains． （3）绿水青山或是金山银山．
What can we do as students？ Just say no to single﹣use plastics like straws， cups and bags． Many people love to drink from a straw or use plastic to carry things， but they are really bad for the environment．
（4）Bring your own chopsticks if you're planning to eat outside． It can be hard to remember．
Just put a pair of chopsticks in your bag before you leave home．
You know you're going to need some water to get you through your day． So carry a bottle（or a cup） with you． （5）That will help you avoid plastic bottles．

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？
（4）In the summer holiday，do you want to be a volunteer to work with Wang Chengbang？Why or why not？
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. |
