Federal regulators Wednesday approved a plan to create a nationwide emergency alert (警報) 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 (估計) more than 48 billions text messages are sent each month.

The plan comes from the Warning Alter and Response Network Act, a 2006 federal law that requires improvement to the nation’s emergency alter system. The act tasked the Federal Communications Commission (FCC) with coming up with new ways to alter the public about emergencies.

“The ability to deliver accurate and timely warning and alters through cell phone 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 alter system by carriers — telecommunication 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 alters.

There would be three types of messages, according to the rules.

The first would be a national alter from the president, likely involving  a terrorists 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 (綁架)emergencies, or so-called Amber Alerts.

The service could be in place by 2010.

What is the purpose of the approval plan?

A. To warn people of emergencies via message.

B. To popularize the use of cell phone.

C. To estimate the monthly number of messages.

D. To promote the wireless industry.

The improvement to the present system is in the charge of ______.

A. CTLA.   B. the Warning Alert and Response Network

C. FCC    D. federal regulators

The carriers’ participation in the system is determined by _______.

A. the US federal government   B. mobile phone users

C. the carriers themselves       D. the law of the United States

Which of the following is true of cell phone users?

They must accept the alert service. 

B. They may enjoy the alert service for free.

C. They must send the alerts to others.

D. They may choose the types of messages.

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

Which of the following would be the best title for the test?

A. Cell Phone Alerts Protecting Students

B. Cell Phone Alerts by Wireless Industry

C. Cell Phone Alerts Natural Disasters

D. Cell Phone Alerts Coming Soon
