Fujitsu, a Japanese technology company, has created a system capable of simultaneously (同时地)
charging multiple portable electronic devices such as mobile phones, digital cameras and laptop computers
without the need for cable connections.
Electric cars users may also eventually be able to charge their vehicles wirelessly using the same
technology, said the company, which developed a sample system at Osaka Prefecture University. Claiming
to be the world"s first of its kind, the technology works on the basis of the transmission of electricity using
magnetic fields between the charger and the electronic device.
The system enables wireless charging at distances of up to several meters. With the final aim of installing
public "charging spots" on the streets in order to enable easy charging around the clock, scientists at Fujitsu
Labs are planning to commercially sell products incorporating the new wireless charging system as early as
2012 but have not yet decided how much they would cost.
"This technology paves the way to integrating compact wireless charging functions into mobile phones
and enabling multiple portable devices to be charged simultaneously without any restrictions on their position
relating to the charger," the company said in a statement.
Mobile phone users in Japan can currently charge their batteries using the disposable portable plug-in
battery-operated device, available at most train stations and convenience stores. However, phone companies
warn long time use of it can damage the phones.
The company added, "We are also looking at applying the results of this work to fields other than portable
electronics, including power transmission between circuit boards (电路板) or computer chips, and providing
mobile charging systems for electric cars."

C. a news report
D. a brief introduction
B. It enables you to charge your device very easily beside the clock
C. It is wireless and makes multiple charging at the same time
D. It can be bought at any formal supermarkets in the city

the US. Some students attend about 3 000 independent public schools called charter schools.
Charter schools are self-governing. Private companies operate some charter schools. They are similar in
some ways to traditional public schools. They receive tax money just as other public schools do. Charter
schools must prove to local or state governments that their students are learning. These governments provide
the schools with the agreement called a charter that permits them to operate.
Charter schools are different because they do not have to obey most laws governing traditional public
schools. Local, state or federal governments cannot tell them what to teach. Each school can choose its own
goals and decide the ways it wants to reach them. Class size is usually smaller than in traditional public schools.
The Bush Administration strongly supports charter schools as a way to re-organize public schools that are
failing to educate students. But some education agencies and unions oppose charter schools. One teachers"
union has just made public the results of the first national study comparing the progress of students in traditional
schools and charter schools.
The American Federation of Teachers criticized the government"s delay in releasing the results of the study,
which is called the National Assessment of Educational Progress. Union education experts say the study shows
that charter school students performed worse on math and reading tests than students in regular public schools.
Some experts say the study is not a fair look at charter schools because students in those schools have more
problems than students in traditional schools. Other education experts say the study results should make charter
school officials demand improved student progress.

D. get the government"s permission
B. their class size is smaller

| A 17-year-old boy, caught sending text messages in class, was recently sent to the vice principal"s office at Millwood High School in Halifax, Nova Scotia. The vice principal, Steve Gallagher, told the boy he needed to focus on the teacher, not his cell phone. The boy listened politely and nodded, and that"s when Mr. Gallagher noticed the student"s fingers moving on his lap. He was texting while being scolded for texting."It was a subconscious act," says Mr. Gallagher, who took the phone away."Young people today are connected socially from the moment they open their eyes in the morning until they close their eyes at night. It"s compulsive." A study this year by psychology students at Covenant College in Lookout Mountain, found that the more time young people spend on Facebook, the more likely they are to have lower grades and weaker study habits. Heavy Facebook users show signs of being more socialable, but they are also more likely to be anxious, hostile or depressed. (Doctors, meanwhile, are now blaming addictions to "night texting" for disturbing the sleep patterns of teens.) Almost a quarter of today"s teens check Facebook more than 10 times a day, according to a 2009 survey by Common Sense Media, a nonprofit.group that monitors media"s impact on families. Will these young people get rid of this habit once they enter the work force, or will employers come to see texting and social-network checking" as accepted parts of the workday? Think back. When today"s older workers were in their 20s, they might have taken a break on the job to call friends and make after-work plans. In those earlier eras, companies discouraged non-business-related calls, and someone who made personal calls all day risked being fired. It was impossible to imagine the constant back-and- forth texting that defines interactions among young people today. Educators are also being asked by parents, students and educational strategists to reconsider their rules. "In past generations, students got in trouble for passing notes in class. Now students are adept at texting with their phones still in their pockets," says 40-year-old Mr. Gallagher, the vice principal, "and they"re able to communicate with someone one floor down and three rows over. Students are just fun-damentally different today. They will take suspensions rather than give up their phones." | ||||||||||||||||
