Federal regulators (管理者) Wednesday approved 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 48 billion text messages are sent each month.
The plan comes from the Warning Alert and Response Network Act, a 2009 federal law that requires improvements to the nation's emergency alert system. The act tasked(派给…工作) 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 2012.
1.What is the purpose of the approved plan?
A. To warn people of emergencies through 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.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
4.Which of the following is true of cell phone users?
A. 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
5.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

California has become the first U.S. state to approve plans to require newly-built homes to include solar equipment.
The state’s Energy Commission voted 5-0 to approve the new rules, which are to take effect in 2020. The rules will deal with most newly-built residential (住宅的) buildings up to three stories high.
The move is California’s latest step aimed at reaching renewable energy targets and reducing greenhouse gas emissions.
California has set a goal of filling half of its electricity needs with renewable energy by 2030. Officials said they had reached 30 percent by the end of 2017. The state’s Governor, Jerry Brown, plans to hold an international climate meeting in September.
①The Energy Commission said the cost of adding solar equipment to a single-family home would be about $9,500. But, the group added that homeowners would save at least $19,000 in energy costs over 30 years.
Robert Raymer is the technical director for the California Building Industry Association. He says the action is a step forward for the wider use of solar power in the U.S. “You can bet every other of the 49 states will be watching closely to see what happens,” he told the Associated Press.
②Solar companies praised the new requirements, which officials have said will likely raise demand for solar equipment in California by 10-15 percent.
The Solar Energy Industries Association called it a “historic decision for the state and the U.S.” It estimated the action would produce “huge economic and environmental benefits,” including bringing tens of billions of dollars into California.
③Some legislative and community leaders argued that Californians cannot afford to pay any more for housing in what is already an extremely high-priced market.
“That’s just going to drive the cost up and make California, once again, not affordable to live in,” said California Assemblyman Brian Dahle.
④Severin Borenstein is an energy economist at the University of California, in Berkeley. He sent an email to the head of California’s Energy Commission to urge the state to reconsider its decision.
He expressed his belief that it is a mistake for California to approve such a policy instead of centering on efforts to develop large solar farms to produce renewable energy. He said these farms would cost much less to operate.
“Every energy economist I know is shaking their head at this,” he told the Wall Street Journal. “In many ways, this is setting the wrong example,” he added.
1.According to the rules to take effect in 2020, newly-built homes are expected to ________.
A. replace large solar farms B. be equipped with solar equipment
C. have the height of three stories D. stop greenhouse gas emissions
2.From what Robert Raymer says, we can know that _______.
A. other 49 states won’t follow in the footsteps of California
B. California can achieve its goal of renewable energy by 2030
C. the action will help homeowners save money in the long term
D. the new rules will probably enjoy a great popularity in the US
3.The sentence “But some individuals and groups were against the new rules.” should be placed in_______.
A. ① B. ②
C. ③ D. ④
4.The purpose of the passage is _______.
A. to show different attitudes towards an approval
B. to express the significance of renewable energy
C. to inform a new way of dealing with climate change
D. to prove a new plan of solar equipment unreasonable

The plan had been made to create a beautiful nature park with a large man-made lake on the outer parts of the city of Zhengzhou, the capital of Henan Province. However, thanks to a terrible trick played by nature, what the officials have ended up with, is a natural sandy mess!
The government wanted to create a beautiful place where people of this busy industrial city could come to relax. But things did not quite turn out that way---shortly after digging up thousands of tons of sand, the underground water dried up. As a result, the dry sand has changed into a Sahara-like desert. While official reports show that the sand is piled up to 10 meters high, some people say that it is ten times more or about a 100-feet high in certain areas.
If that is not bad enough, the sand hills that now spread across an area the size of four football fields, have influenced the environment. What’s worse is that on windy days, the dry sand moves into the city center, making it almost impossible to drive and forcing people to wear face masks and protective eyewear to prevent the sand from getting into their eyes, nose, and mouth.
In an act of trying to keep the sand and provide the illusion(幻想) of green fields, the officials have even tried covering it with a green plastic netting. However, that has not done much to improve the terrible situation!
As you can imagine, many of Zhengzhou’s residents are upset by the disaster. They think that desert wasteland that looks nothing like the green landscape they were promised, has resulted in polluting their pleasant city environment. Some think it is even stopping businessmen from coming to the city.
1.The author may agree that it is_________ to build a large man-made lake.
A. possible
B. impossible
C. great
D. interesting
2.The dry sand has changed into a Sahara-like desert because________.
A. the weather in Zhengzhou is too dry
B. there are enough trees in Zhengzhou
C. they haven’t finished digging the lake
D. there is no underground water
3.What kind of pollution have the sand hills caused?
A. Light pollution. B. Water pollution.
C. Air pollution. D. Sound pollution.
4.What do Zhengzhou’s residents think of the man-made lake?
A. Scary. B. Small.
C. Helpful. D. Great.
