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.

GCSEs（General Certificate of Secondary Education，普通中等教育证书）encourage "teaching to the test" and may be past their sell-by date, according to Britain"s leading business organization. The Confederation of British Industry（CBI） warns that the qualification is stopping teachers delivering an "inspirational classroom experience" and should be replaced.
John Cridland, the CBI director general, said industry faced a shortage of key skills, particularly in science and maths. The CBI（英国工业联合会）, which represents more than 240,000 companies, is also concerned about the 40% of young people who fail to achieve the benchmark of five good GCSE passes including English and maths. The percentage of pupils who reach this standard is the main measure of school success.
Speaking at the launch of a CBI inquiry into education, Cridland argued that abandoning GCSEs could help deliver a full education. "There"s something about this GCSE limitation which produces a form of learning ------ teaching for the test.’’
"It frustrates teachers because it stops them delivering that inspirational classroom experience."
The CBI head suggested that raising the school leaving age to 18 – a change that comes into effect in 2015 – is an opportunity to reform the system. "It seems to me that we"ve raised the participation age to 18 and we"re left with an education system that focuses on 16," said Cridland. More than 600,000 children in England, Wales and Northern Ireland are due to take GCSEs this summer.
Many other countries do without a public exam at 16. Finland, the highest performing school system in Europe, has just one public exam, at 18, though children are regularly tested at younger ages.
小题1:What does the author intend to tell us in paragragh1？
| A．“Teaching to the test” should be encouraged. |
| B．We should stop teachers delivering “inspirational experience”. |
| C．The current qualification is out of date and should be replaced. |
| D．The Confederation of British Industry should be replaced. |
| A．The British GCSEs are no longer practical and should be reformed. |
| B．In the GCSEs system , teachers don’t have freedom. |
| C．Five good GCSEs is hard to achieve. |
| D．The British Education Department will reform education system. |
| A．success | B．target | C．standard | D．excellent grades |
| A．TV series | B．radio news |
| C．newspaper education section | D．government report |
The High School Research Program offers high school students guidance with researchers in Texas A&M’s College of Agriculture and Life Sciences. Jennifer Funkhouser, academic adviser for the Department of Rangeland Ecology and Management, directs this four-week summer program designed to increase understanding of research and its career potential.
Several considerations go into selecting students, including grades, school involvement and interest in science and agriculture. And many students come from poorer school districts, Funkhouser says, “This is their chance to learn techniques and do experiments they never would have a chance to do in high school.”
Warner Ervin of Houston is interested in animal science and learned how to tell male from female mosquitoes(蚊子）.His adviser, Craig Coates, studies the genes of mosquitoes that allow them to fight against malaria and yellow fever. Coates thought this experience would be fun and helpful to the high school students.
The agricultural research at A&M differs from stereotypes. It’s “molecular(分子）science on the cutting edge,” Funkhouser says. The program broadened students’ knowledge. Victor Garcia of Rio Grande City hopes to become a biology teacher and says he learned a lot about chemistry from the program.
At the end of the program, the students presented papers on their research. They’re also paid $600 for their work-another way this program differs from others, which often charge a fee.
Fourteen students got paid to learn that science is fun, that agriculture is a lot more than milking and plowing and that research can open many doors.
小题1:The research program is chiefly designed for _______.
| A．high school advisers from Houston |
| B．college students majoring in agriculture |
| C．high school students from different places |
| D．researchers at the College of Agriculture and Life Sciences |
| A．had little chance to go to college |
| B．could often take part in the program |
| C．found the program useful to their future |
| D．showed much interest in their high school experiments |
| A．entered that college | B．wrote research reports |
| C．paid for their research | D．found way to make money |
| A．important | B．favorable |
| C．astonishing | D．advanced |
There are different forms of color blindness. In some cases a man can not see deep red. He may think that red, orange and yellow are all shades of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green - a strange world indeed.
Color blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called “cones”. These help us to see in a bright light and to tell difference between colors. There are also millions of “rods” but these are used for seeing when it is nearly dark. They show us shape but no color.
Some insects have favorite colors. Mosquitoes (蚊子) like blue but do not like yellow. A red light will not attract insects, but a blue lamp will. In a similar way human beings also have favorite colors. Yet we are lucky. With the aid of the cones in our eyes we can see many beautiful colors by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible (看不见的) colors around.
小题1:Why do some people say it is safer to be driven by women?
| A．Women are more careful. |
| B．There are few color-blind women. |
| C．Women are fonder of driving than men. |
| D．Women are weaker but quicker in thinking |
| A．color and its surprising effects |
| B．women being luckier than men |
| C．danger caused by color blindness |
| D．color blindness |
| A．tell orange from yellow |
| B．see in weak light |
| C．kill mosquitoes |
| D．tell different shapes |

Music education has received a lot of attention． Learning to play an instrument can help children improve math, science, and language skills． One study in Canada tracked children"s IQ scores for nine months, discovering that children who studied music had the biggest test score improvements． The secret may lie in the way reading music and playing notes uses several areas of the brain, increasing our ability to learn school subjects． For example, reading notes improves spatial （空间的） reasoning skills, which are helpful in solving math problems like fractions（分数）．
Music is also used for medical purposes, such as the treatment of diseases which affect memory． The secret lies in the way the brain processes music． One area near the forehead, the medial prefrontal cortex, connects music with memories stored in two other areas: the amygdale and hippocampus． That"s why an old song can remind you of something that happened years ago． For patients suffering from diseases like Alzheimer"s, listening to music can help unlock buried memories by strengthening musical pathways to memories．
With the evidence of music"s benefits pouring in, it"s no wonder some countries make music study a part of their education systems． People are recognizing that more than just a form of entertainment, music is also great for the brain．
小题1:Scientists are studying music because _______．
| A．music can be used for medical treatments |
| B．music plays a very important role in our lives |
| C．our brains can possess music in different ways |
| D．music education has received a lot of attention |
| A．Those who already had high IQs． |
| B．Those who had always played music． |
| C．Those who could not play any instrument． |
| D．Those who studied music for a period of time． |
| A．Spatial reasoning． | B．Alzheimer"s． |
| C．The amygdale and hippocampus． | D．The medial prefrontal cortex． |
| A．Music and health | B．Music and the mind |
| C．Music and education | D．Music and instruments |
A learning disability is not a problem with IQ or motivation (动机). Kids with learning disabilities aren’t lazy or slow. In fact, most are just as smart as everyone else. Their brains are just wired (装电线) differently. Simply put, children and adults with learning disabilities see, hear, and understand things differently. This difference affects how they receive and process (处理) information. This can lead to trouble in learning new information and skills, and putting them to use.
It can be tough to face the possibility that your child has a learning disorder. No parents want to see their children suffer. You may wonder what it could mean for your child’s future, or worry about how your kid will make it through school. But the important thing to remember is that most kids with learning disabilities are just as smart as everyone else. They just need to be taught in ways that suit their unique learning styles.
It’s not always easy to tell whether a child has learning disabilities, for learning disabilities look very different from one child to another. One child may struggle with reading and spelling, while another loves books but can’t understand math. Still another child may have difficulty understanding what others are saying or communicating loud. However, some warning signs are more common than others at different ages. If you’re aware of what they are, you’ll be able to catch a learning disorder early and quickly and take steps to help your child as quickly as possible.
小题1:From the passage, we can infer that_______.
| A．students with learning disabilities look quite different from normal students |
| B．students with learning disabilities can’t do well in their studies |
| C．only few students with learning disabilities are as clever as normal students |
| D．it is quite possible for a students with learning disabilities to succeed in their studies |
| A．Learning about learning disabilities. |
| B．How to prevent learning disabilities. |
| C．Ways to identify learning disabilities. |
| D．Different learning disabilities. |
| A．Some ways which help parents teach their children with learning disabilities better. |
| B．Some suggestions on how to get along with their children with learning disabilities. |
| C．Some parents may have difficulties in helping their children with learning disabilities. |
| D．Some warning signs which show that a child may have learning disabilities. |
