Federal regulators 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 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.

If your job requires a lot of sitting, you could be putting your health at danger.
The American Journal of Epidemiology (流行病学) did a study in 2010 on the correlation (相互联系) between sitting and an individual's physical health. In the study, 53,440 working men and 69,776 working women were surveyed on their time spent sitting. The subjects were all disease free when employed. The researchers identified 11,307 deaths in men and 7,923 deaths in women during the 14-year follow-up.
The findings: Women who reported sitting for more than six hours per day had an approximately 40 higher all-cause death rate than those who reported less than three hours a day, and men had an approximately 20 higher death rate.
Well, now's a fine time to get this information. But why didn't they tell me this years ago? I would have planned on taking a more active job instead of the sedentary (坐着的) job of an editor.
So what can you do if you have to work for a living at a job that requires a lot of sitting? Here are some ideas:
Take frequent breaks. It is recommended that workers vary activities, change their position, and take short breaks every 20 minutes to rest muscles and increase blood circulation. Get a standing desk. Some studies have shown that working from an upright position may be better for health. The serious fitness people can even purchase a treadmill (跑步机) desk. It only goes about one mile per hour. Have a walking meeting. If your group is kind of small, going for a walk while discussing topics is a good alternative.According to the text, the study in 2010 ______.

In 1992, I had just launched a new business called Video News International.
It was the world's first video journalist network. The idea was to cover news and sell the service to news organizations.
One day, a young intern (实习生) who was working for us named Anthony Lappe pulled me aside.
"There is something you have to see," he told me. "Comcast is doing this really cool thing."
"What?"
"The Internet," he said. "It's going to be really big."
Anthony later introduced me to the head of the Internet project.
"We are looking for content to put on our network here," the guy said to me.
Well, I said I had lots of content to offer.
The guy's eyes lit up. "Cool," he said. "We would like to put it on our network."
Well, I was always looking for new clients.
"What are you going to pay?" I asked.
He said that they could not pay anything for the content, but they would set up a URL for me.
"What's that?" I asked.
"It's kind of like your address on the web."
"What would I do with this URL thing?"
"Well, it could be your business."
"I don't see how it is a business, and there's not even any advertising," I cleverly replied.
"Not yet," he said. "But one day there might be."
I thought about it for two seconds.
"Naah..." I said. "I've got bigger fish to fry. I've got to be going now. Maybe we can cooperate next time."
And I walked out.
Idiot!

My friend had mentioned the other day that her father had a lot of children's toys he was looking to give away. She knew I have a three-year-old daughter so she thought of me first. I told her I would love it if I could get some nice things for my daughter, which I wouldn't otherwise have been able to afford.
When I met her father, he began to explain he was too poor once and that he would hate to throw away things that can be very useful.
Before he showed me what he was giving away, I thought the toys would be mostly lego's(乐高积木) or things like that. When he was showing me around I saw a bed, a slide, a kitchen set and many other things that just blew my mind. He told me to write a list of everything my daughter could use and as my eyes were wide, he told me not to feel guilty. He said I was helping him by getting rid of the stuff.
As I was looking around I did feel guilty, but I tried to remain more grateful than guilty. Every time I tried to thank him for giving me and my daughter all this wonderful stuff he would thank me right back. I wanted to believe that he was just thanking me so that I wouldn't feel so guilty but in reality I believe that he was as grateful as I was that these toys would be put to good use.
In the eyes of charity, it makes sense to feel grateful, but guilt is just as normal. I know that we could have lived without a slide, which is why I do feel guilty, but I am grateful all the same because my daughter really does enjoy all these nice things!Why did the old man want to give away his toys?
| A．He wanted to help those poor children. |
| B．He was wealthy enough to buy new toys. |
| C．He wanted to make full use of those toys. |
| D．He needed some space for more useful things. |
In the writer's opinion, the old man felt grateful because________.
| A．he wanted to make her more guilty |
| B．he wanted her to take the toys quickly |
| C．the toys would be put to good use |
| D．he finally got rid of the stuff |
What can we know from the passage?
| A．The writer took all the toys home. |
| B．The old man was a kind and thoughtful person |
| C．The writer wanted to refuse the stuff when she first saw them. |
| D．The writer's daughter enjoyed the slide most among all the stuff. |
How did the writer feel when given the stuff?
| A．Guilty and honored. | B．Grateful and respected. |
| C．Honored and respected. | D．Guilty and grateful. |
In a computer age，a broadband Internet connection is very popular now．Whether cable or mobile broadband，today’s connections are many times faster than those in the early days. Videos play smoothly, complex websites load quickly，and files download much faster than ten years ago．And the files are much bigger too．
There’s a hidden problem：You have to live near enough to a major city to get broadband Internet. If you don’t，it's slow dial-up access for you. And for those living really far out，there may be no Internet access at all．
Technology experts often talk about the “last mile” problem，which refers to the difficulty of bringing Internet access to remote locations．In cities and suburbs(郊区)，it's relatively easy to provide access for everyone．It is much more difficult to deliver access to those living far from cities，especially in developing countries．Internet service providers, for their part，have been reluctant to provide access to sparsely(稀疏地)populated areas．The handful of Internet users they would reach wouldn’t cover the expense.
But every year, technological advancements allow of more and more Internet users. Most broadband connections today run over existing cable TV and telephone lines although these technologies aren’t available everywhere．
Some companies have delivered the Internet over standard power lines. Advancements in cheaper more efficient fiber optics cables(光纤电缆)promise to bring extremely fast Internet connections to more users．Still, the“last mile”problem remains hard to deal with．There will always be somewhere that doesn’t have an affordable broadband connection．But someday that might not matter．If the rapid progress in cell phone technology is any indication，it may not be too long before an Internet connection simply follows you wherever you go.Which of the following is TRUE according to the passage?
| A．Internet connections have been popular everywhere． |
| B．Internet service providers are willing to care about rural(农村的)customers． |
| C．The problem of Internet access hasn’t been completely dealt with. |
| D．Computer can’t become popular in developing countries． |
Paragraph 4 mainly tells us that technological advancements_______.
| A．make TV and telephone available everywhere |
| B．bring great change to people’s everyday life |
| C．bring faster Internet connections to users |
| D．make it possible for more people to use the Internet |
What may eventually settle the“last mile”problem?
| A．The broadband connection’s getting faster． |
| B．The rapid progress in cell phone technology． |
| C．More and more Internet connections． |
| D．More and more Internet users. |
The best title for this passage may be________．
| A．Internet Connection Problems |
| B．Internet Connections Need Improving |
| C．Progress in Internet Connections |
| D．Internet Connections Today |
