Bicycle lights may not exactly be a problem that needs solving, but the following can be said about most of them ---- they’re easily stolen if left on an unattended bike. People riding at dusk can forget to turn them on, and those same people can forget to turn them off when they reach their destination. Well, the makers of the Blink/ Steady Bike Light have set out to address all of those shortcomings.

The waterproof(防水的) Blink/ Steady is so far only available as a tail light, although a head light is on the way. It’s fixed onto the bike’s seat post. A built- in photosensor(感光器) tells when it’s become dark enough for the light to be required, and allows it to come on once you begin the riding. According to the producers, it isn’t fooled by things such as headlights or streetlights. The light also contains an accelerometer, also known as a motion sensor, which can tell when the bike is in motion.

Between the two sensors, this means the light will come on only once it’s dark enough, and the bike is moving. Even when stopped at red lights, the small movements of the rider will reportedly be enough to keep the light activated---- it’ll go out after 30 seconds of complete inactivity. While this does mean that the two sensors are continuously powered up, they go into a very low---- power sleep pattern when the bike is sitting, unused.

Light is provided by two5- watt LEDs, seeable over a range of 180 degrees. And power comes from two AAA batteries, which provided up to 200 hours of continuous run time. The designers and engineers behind the Blink/ Steady are now raising money for its commercial production. About US $95 will get you one if they become available.

1.The first paragraph is mainly to mean that______.

A. bicycle lights are worth a research

B. bicycle lights are not a problem at all

C. bicycle lights are easy to deal with

D. bicycle lights are difficult to turn off

2.According to the text, the Blink/Steady Bike Light is sensitive to______.

A. the weather       B. streetlights      C. headlights      D. natural light

3.Why is there an accelerometer in the Blink/ Steady Bike Light?

A. To protect the bike against water.

B. To tell if the bike is moving.

C. To make the bike easy to ride.

D. To judge the speed of the bike.

4.What can be inferred about the Blink/ Steady Bike Light?

A. It will be turned off immediately if the bike stops.

B. The traffic lights have no effect on the light.

C. It won’t use any power if the bike is unused.

D. It must meet two requirements if it comes on.

Children today spend less time outdoors than ever before and it may be harmful not only to their physical health, but also to their cognitive (认知的) development.

A year-long study, recently published in the Sciences, found that elementary school children who were exposed to more green space within or directly outside their school showed improved learning and memory. The findings reinforce (加强) that of a recent six-year study on 905 Massachusetts public elementary schools, which found that students in schools that had more “greenness” in their surroundings reported higher scores on standardized testing in English and math. “There is an expanding body of scientific evidence linking the human experience in the natural world to better physical and mental health and improved cognitive abilities,” journalist Richard Louv, co-founder of the Children & Nature Network, said in an email to The Huffington Post. “An increasing number of homeschoolers, nature preschools, independent primary and secondary schools, and forward-thinking public schools are incorporating (并入) nature experience into learning.”

The new study was conducted on more than 2,500 children in second, third and fourth grade at 36 primary schools in Barcelona, Spain. Researchers found that the students who attended schools with more green space showed a 5 percent improvement in the short-term memory that’s critical for reasoning, learning and comprehension. But their inattentiveness decreased slightly.

Spending time outside could have a number of benefits for children beyond improved memory and attention. Another recent study found that adventurous outdoor play such as climbing, rough and tumble (翻筋斗) play, and exploring alone improves children’s physical health while also help them develop creativity and social skills greatly.

Some schools are starting to take notice, creating more space for children to enjoy being in nature, including community gardens, outdoor playgrounds and small parks.

1.What did the study lasting a year find?

A. The cognitive abilities of children today decreased.

B. The findings of another six-year study were incorrect.

C. Being exposed to nature was beneficial to the learning of pupils.

D. Students had higher scores on testing in English and math than before.

2.According to the passage, what can we know about Richard Louv?

A. He discourages students from getting close to nature to gain experience.

B. He is one of the founders of the Children & Nature Network.

C. He conducted the study on 905 Massachusetts public elementary schools.

D. He often contributes articles to The Huffington Post.

3.Spending time in green space may have little effect on children’s __________.

A. inattentiveness　　　 B. creativity

C. communication　　 　 D. learning

4.In which column of a newspaper can you see this article?

A. Entertainment.　　　 B. Travel.

C. Parenting.　　　 　　 D. Education.

Try not to download things from strangers. 5., but be careful that you don’t get viruses or hacked by such downloads.
