　　Radioactivity is dangerous. It may cause skin burns; it may destroy good tissues (组织) and it may cause illness that could be passed on to our children and grandchildren, In case of exposure (暴露) it may even cause death.

　　In the early days of radioactivity, scientists did not realize these dangers, Marie and Pierre Curie, after having worked for a while with radioactive materials, noticed that their fingers were reddened and swollen (红肿) and the skin was peeling off. Henry Becquered carried a small tube with radium in it in his waistcoat pocket, and was surprised to find a burn on his chest. Other early workers also reported burns and harm of different kinds.

　　The strange fact that it can harm without causing pain is the warning signal we expect from harmfulness. Pain makes up pull back our hands from a fire or a hot object, but a person carrying radioactive materials had no way of telling whether he is touching something too “hot” for safety. Besides, the “burns” or other harmfulness that radioactivity produces may not appear for weeks. A person may have been hurt without knowing it for some time .

More Chinese are seeking out the surgeon’s knife to improve their looks.Yet the tragic death of the former Super Girl Wang Bei has made people aware of the risks of cosmetic surgery, which is becoming increasingly popular. Wang Bei，24，is said to have gone under the knife in Wuhan，to jump-start her stage-show career. It seems that the ambitious singer has finally achieved the fame and influence after her death.

For years Miss Lu expected a plastic surgery to make her jaw fashionable narrow and her face smaller. She finally decided against it after hearing of the death of Wang Bei. "Wang Bei’s death rang the warning bell for me，"Miss Lu said in her blog." It was frightening and I gave up the plan. "

A common thread of online discussion is why someone considered beautiful was so dissatisfied with her looks. Some netizens said Wang was a victim of society’s impractical standard of beauty：double eyelids，and the pointed chin typical of Western actresses.

The Haitian tsunami gave scientists a chance to find out how well vital and potentially life-saving warning systems were working.

Noaa’s Pacific Marine Environmental Laboratory has developed a warning system that picks up signals of tsunamis directly from the sea-floor.

It is called Dart-the Deep-ocean Assessment and Reporting of Tsunamis. If seismometers(地震仪) detect an earthquake, the Dart buoys（浮标） will determine what is happening to sea levels, and whether a big wave might be on the way. This information is then sent via satellite to a central location which can organize an alarm. Within 50 minutes of the Haiti earthquake, this system was able to issue an alarm to other countries in the Caribbean to say that a small tsunami had been caused to start, and that was unlikely to affect them.

Dr Bernard said, “The first 30 minutes following the earthquake, we have to rely on education.” The critical aspects of this are: do you feel the earthquake; do you see the ocean draw down; and do you hear that loud roar? If so, you should run for higher ground.

“But after the first few minutes, it’s crucial that we have the technology—the measurements to avoid unnecessary evacuation(疏散撤离)and tell people when it is safe to return.” Right now, there are 50 of these Dart buoys all over the globe—four of which are in the Caribbean.

Dr Bernard says that, with 75 to 100 buoys worldwide, this system could provide global tsunami warnings within one hour.

“That’s for everywhere we know that tsunamis have happened. If we wanted to go to half an hour detection, we could probably double or multiply by four times that number,” he said.

“In some countries, including Haiti, there may not be enough resources to support a specific tsunami warning centre for something that happens so infrequently.”

He said that this system was relatively inexpensive to fix and operate.

“To get it down to an hour for everywhere affected would cost $50m initial investment and then 10% of that to maintain it,” he said.

“That’s not a terribly expensive system considering the potential savings of lives.”

1.In which section would you probably read the passage in a newspaper?

A. Education and Society

B. Culture and Leisure

C. Science and Technology

D. Health and Medicine

2. How many buoys would at least be needed for global tsunami warnings within half an hour?

A. 150

B. 100

C. 75

D. 50

3.Which of the following can be inferred from the passage?

A. The system can warn people of the coming of tsunami directly after the earthquake.

B. We can’t escape the danger of tsunami within 30 minutes following the earthquake.

C. Each country can easily afford a tsunami warning centre though it seldom happens.

D. It’s worthwhile to spend money on the warning system for possible savings of lives.

4. Which of the following would be the best title for this passage?

Federal regulators(调整者) 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 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.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 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

________ the warning message, more deaths would have been caused in the flood according to the report from Xinjiang．
