Your smartphone can do a lot of things. It can call people. It connects to the Internet. It enables you to play fun games. But there is a dark side to this smart little equipment of yours----- it might also spread disease.
“People are just likely to get sick from their phones as from handles of the bathroom, ” Jeffrey Cain, the president of the American Academy of Family Physicians , told The Wall Street Journal.
This may be hard to believe, but scientists reached this conclusion after they tested eight cell phones from an office in Chicago. All the tested phones showed high numbers of coliforms (大肠菌), a kind of bacteria found in human waste , with about 2700 to 4200 units of the bacteria on each phone. The bacteria can cause flu, pinkeye and other diseases . That is right --- your phone is covered in our human waste.
Although computers, keys and pens carry germs (细菌) , our phones get far dirtier. They touch a lot of things, including our hands and the inside of our pocket or purse. We take them almost everywhere: the bus, the subway and who hasn’t played Angry Birds or Fruit Ninja while sitting on the toilet?
“Some things that we think are personal are actually more public than we imagine,” Cain said. What is even worse is that after the phone returns from its dirty trip, it then spends most of its time cozying up to our faces. You don’t think about how often you touch your phone to your face, do you? Our noses, mouths and ears are all warm and rich in grease (油脂) , an environment that germs really like.
So how do you keep your phone clean? Alcohol is effective when used to kill germs from the back and side of your phone. But it might harm the screen. There is one simple and reliable way you can reduce the germs on your phone’s surface: wash your hands regularly.

查看习题详情和答案>>Federal regulators Wednesday approved (批准a plan to create a nationwide emergence 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 48billion text messages are sent each month.
The plan comes from the Warning Alert and Response Network Act, a 2006 federal law that requires improvements 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.
1.What is the purpose of the approved plan?
A．To warn people of emergencies via messages.
B．To popularize the use of cell phones.
C．To estimate the monthly number of messages.
D．To promote the wireless industry.
2.The improvement to the present system is in the charge of________.
A．CTIA B the Warning Alert and Response Network
C．FCC D．federal regulators
3.An alert message will NOT be sent if________.
A．a child loses his way
B．a university shooting happens
C．a natural disaster happens
D．a terrorist attack occurs
4.Which of the following would be the best title for the text?
