A new study found that inner-city kids living in neighborhoods with more green space gained about 13% less weight over a two-year period than kids living among more concrete and fewer trees. Such findings tell a powerful story. The obesity epidemic(肥胖癥的流行)began in the 1980s, and many people think it results from increased portion(食物) sizes and inactivity , but that can't be everything. Big Macs and TVs have been with us for a long time. "Most experts agree that the changes were related to something in the environment," says Thomas Glass of the Hopkins School of Public Health. That something could be a shrinking of the green.
The new research, published in the American Journal of Preventive Medicine, isn't the first to associate greenery with better health, but it does get us closer to identifying what works and why. At its most straightforward, a green neighborhood simply means more places for kids to play — which is important since time spent outdoors is one of the strongest links to children's activity levels.
Glass warns that most studies don't necessarily prove a link between greenness and health, but they're helping spur action. In September the U.S. government approved the No Child Left Inside Act to encourage public initiatives (積極性)aimed at exposing kids to the outdoors.
Finding green space is, of course, not always easy, and you may have to work a bit to get your family a little grass and trees. If you live in a suburb or a city with good parks, take advantage of what's there. Your children in particular will love it — and their bodies will thank you.
1.According to the passage, what might cause children’s inactivity?
A. Less concrete and more trees
B. Increased portion sizes
C. A green neighborhood
D. A shrinking of the green
2.According to the passage, which of the following statements is wrong?
A. Big Macs and TVs have something to do with obesity.
B. If a 100-pound man lives in green space for 2 years, he will lose 13 pounds.
C. Kids should be exposed more to outdoors.
D. Kids gain less weight living in a suburb or a city with good parks.
3.What does the underlined word “spur” in the fourth paragraph mean?
A. improve B. take
C. encourage D. stop
4.What might be the best title of the passage?
A. The obesity epidemic B. Slimmer in the grass
C. Causes of obesity D. Prevention of obesity

Batteries can power anything from small sensors to large systems.While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves.University of Missouri(MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient.
“To provide enough power, we need certain methods with high energy density(密度)”,said Jae Kwon, assistant professor of electrical and computer engineering at MU.“The radioisotope(放射性同位素) battery can provide power density that is much higher than chemical batteries.”
Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro / nanoelectromechanical systems (M/NEMS).Although nuclear batteries can cause concerns, Kwon said they are safe.
“People hear the word ‘nuclear’ and think of something very dangerous,” he said, “However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems.”
His new idea is not only in the battery’s size, but also in its semiconductor(半導(dǎo)體).Kwon’s battery uses a liquid semiconductor rather than a solid semiconductor.
“The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure(晶體結(jié)構(gòu)) of the solid semiconductor,” Kwon said, “By using a liquid semiconductor, we believe we can minimize that problem.”
Together with J.David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery.In the future, they hope to increase the battery’s power, shrink its size and try with various other materials.Kwon said that battery could be thinner than the thickness of human hair.
1.Jae Kwon gave examples in Paragraph 4_________.
A.to show chemical batteries are widely applied.
B.to introduce nuclear batteries can be safely used.
C.to describe a nuclear-powered system.
D.to introduce various energy sources.
2.According to Jae Kwon, his nuclear battery _______.
A.uses a solid semiconductor
B.will soon replace the present ones.
C.could be extremely thin
D.has passed the final test.
3.The text is most probably a ________.
A.science news report B.book review
C.newspaper ad D.science fiction
