Federal regulators Wednesday approved a plan to create a nationwide emergency alert（警报）system using text messages delivered to cell phones.
Text messages have exploded in popularity in recent years，particularly among young people.The wireless industry’s trade association, CTIA，estimates（估计）more than 48 billion text messages are sent each month.
The plan comes from the Warning Alert and Response Network Act，a 2006 federal law that requires improvement to the nation's emergency alert system.The act tasked the Federal Communications Commission (FCC) with coming up with new ways to alert the public about emergencies.
“The ability to deliver accurate and timely warnings.and alerts through cell phones and other mobile services is an important next step in our efforts to help ensure that the American public.has the information they need to take action to protect themselves and their families before, and during,disasters and other emergencies. ”FCC Chairman Kevin Martin said following approval of the plan.
Participation in the alert system by carriers—telecommunications companies is voluntary, but it has received solid support from the wireless industry.
The program would be optional for cell phone users. They also may not be charged for receiving alerts.
There would be three different types of messages，according to the rules.  
The first would be a national alert from the president，likely involving a terrorist attack or natural disaster.The second would involve “approaching threats，”which could include natural disasters like hurricanes or storms or even university shootings. The third would be reserved for child abduction（绑架）emergencies,or so-called Amber Alerts.
The service could be in place by 2010.
【小题1】 What is the purpose of the approved plan?

The popular college rankings focus primarily on prestige as measured by the SAT scores of incoming students and how many applicants are turned away． An initiative（措施）started last fall by the Obama administration could help families go beyond these limited, and far too easily exploited, indexes to learn quickly and easily how a college is compared with its competitors nationally on important criteria like graduation rates, what a degree actually costs and how much debt a student can expect to run up by graduation day．
If the federal government makes it legally necessary to disclose this information in a clear and consistent（一贯的）way, as it should, families will be better able to make informed college choices． And this will help put pressure on colleges that perform poorly to improve．
Critics may regard this initiative as an example of government overreach． But given that the federal government spends nearly $190 billion a year on higher education aid to students, it has a legitimate interest in making sure that the money flows to the schools that best meet their responsibilities to families and students．
Congress has taken some steps to require greater transparency（透明）from colleges． The 1990 Student Right to Know Act, for example, required colleges and universities that receive federal aid to disclose graduation rates． And the 2008 Higher Education Opportunity Act required schools to offer a way for consumers to determine actual costs after student aid is taken into account．
But many colleges have done a poor job of obeying federal disclosure rules, and much of the available information is not in one place． The administration’s new efforts would enforce reporting requirements and provide some new tools．
President Obama wants to expand campus-based aid to about $10 billion from the current $2．7 billion． He has proposed moving money away from colleges that fail to control tuition increases or provide good value to others that do a better job． That is a worthy idea in principle, but he will need strong data-based evidence to determine how colleges are doing．
The transparency initiatives are a good place to start and should be embraced by both parties in Congress． If students and families, facing higher tuition and rising debt, are to make sound choices, they need more and better information．
【小题1】Why did the Obama administration start the initiative last fall?

My oldest child, Emma, just returned to campus after a long holiday break to finish up her last period of college. These days, friends and family have begun flooding me with one question: What is she going to do after graduation?

The job market is, after all, awfully tough. Just this month the Federal Reserve Bank published a study showing that “recent graduates are increasingly working in low-paid jobs or working part-time.” The bright spot, according to the study, is for students who majored(主修) in STEM — science, technology, engineering and mathematics — areas in which recent graduates “have tended to do relatively well”.

But Emma is a student of the humanities(人文) at a small college. She’s an American Studies major with a focus on the politics and culture of food. For quite a while, I think her field of study is so fashionable right now that I’m not the least bit worried she will find a good job. Yet the more I’ve thought about it, the more I’ve decided to be honest. “I’m not sure what Emma is going to do,” I now say. “But she’s gotten a great education and has really found her interest. — and I know those things will serve her well over the course of her life.”

Nowadays, more and more universities and colleges are being measured by the salaries of their recent graduates. In this climate, encouraging your kid to study the humanities, seems, at best, unwise or, at worst, unconcerned with earning a living. But a college is not a vocational(职业) school. And promoting STEM subjects should not be society’s only answer to helping the next generation grow in a competitive world.

From the beginning, we never urged Emma to pick a college or a major with an eye on its expected return on money, as more and more families are doing. To Emma, what really matters will be something that we may not be able to measure for quite a long time: Emma’s contribution to the world and how happy she is in it.

Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain-computer interface (BCI) technology could help people with disabilities send commands to machines.

Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated a small robotic wheelchair directed by a person's thoughts.

In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.

“Our brain has billions of nerve cells. These send signals through the spinal cord (脊髓) to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles.” Tavella says. “Our system allows disabled people to communicate with external world and also to control devices.

The researchers designed a special cap for the user. This head cover picks up the signals from the scalp (头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.

Prof. Millan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. “The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices. One example is this wheelchair.”

He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time.

B. computer→cap→scalp→wheelchair

C. scalp→cap→computer→wheelchair

D. cap→computer→scalp→wheelchair

4.Which of the following would be the best title for the text?

A. Switzerland, the BCI Research Center

WASHINGTON---At least four more U.S. air-traffic controllers are caught nodding off on the job at three separate airports across the nation, the government said Wednesday.
The controller working alone in the tower fell asleep and was out of communication for 16 minutes while a medical flight carrying a patient was trying to land at about 2 A.M. Wednesday at Reno-Tahoe International Airport in Nevada, the Federal Aviation Administration (FAA) said in a statement.
The FAA announced that it is also investigating a controller who fell asleep Monday at Boeing King County International Airport in Seattle and two controllers who were unresponsive at McGhee Tyson Airport in Knoxville, Tennessee on Feb.19.
“I am sick of this,” Senate Commerce, Science and Transportation Chairman Jay Rockefeller, a West Virginia Democrat, said in a statement. “We can’t have a system where some of the people responsible for safety are asleep at the switch.”
As the incidents pile up, sleep experts say it demonstrates that the agency faces a systemic issue with the thousands of people expected to work through the night in safety-critical jobs. Scientific research shows that workers on midnight shifts make more errors because it is so difficult for the body to adapt to sleeping during the day, they say.
The agency will add an extra controller at the 27 towers staffed with one worker on the midnight shift, the FAA statement said.
Representative John Mica, the Florida Republican who chairs the House transportation committee, criticized the decision to add controllers. “Only in the federal government would you double up on workers, averaging $161,000 per year in salary and benefits, that aren’t doing their job,” Mica said in a statement. Mica has pushed legislation that would allow as many as 90 smaller airports to switch from federal to private controllers.
“People have known these problems with fatigue（疲劳）have existed for years,” said John Goglia, a Boston-based aviation safety consultant. “They’re now showing up. The FAA is admitting they exist. Now the FAA needs to work on it.”
The four controllers in Nevada, Seattle and Texas have been suspended(暂时停职) during the investigations, the FAA said.
