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.

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.

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

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 text?

       A．Cell Phone Alerts Protecting Students

      B．Cell Phone Alerts by Wireless Industry

       C．Cell Phone Alerts of National Disasters

       D．Cell Phone Alerts Coming Soon

Along the river banks of the Amazon and the Orinoco there lives a bird that swims before it can fly, flies like a fat chicken, eats green leaves, has the stomach of a cow and has claws(爪)on its wings when young .They build their homes about 4.6m above the river ,an important feature(特征)for the safety of the young. It is called the hoatzin.

    In appearance，the birds of both sexes look very much alike with brown on the back and cream and red on the underside .The head is small, with a large set of feathers on the top, bright red eyes, and blue skin. Its nearest relatives are the common birds, cuckoos. Its most striking feature ,though, is only found in the young.

    Baby hoatzins have a claw on the leading edge of each wing and another at the end of each wing tip .Using these four claws ,together with the beak(喙),they can climb about in the bushes, looking very much like primitive birds must have done. When the young hoatzins have learned to fly ,they lose their claws.

During the drier months between December and March hoatzins fly about the forest in groups of 20 to 30 birds, but in April, when the rainy season begins, they collect together in smaller living units of two to seven birds for producing purposes.
