2010年6月英语六级全真预测试卷及答案解析(3)

　　Crisis Communications

　　Can first responders—police, fire and medical—talk to one another? On September 11, firefighters died inside the World Trade Center because they could not make contact with police helicopters trying to radio warnings. Incompatible communications is a country-wide problem, and converting or replacing decades-old radio systems can be a long, expensive process. Cities have gotten a big boost if they've taken part in RapidCom, a DHS program providing technical assistance and training that speeds up the transition.

　　Has the city adopted E911? Many cities have upgraded their 911 call centers in recent years, but they're even better prepared if they've incorporated "E911" (or "enhanced 911"). This technology enables emergency operators to identify the precise location of cell-phone callers through GPS systems. If you wind up stranded in floodwaters, E911 could save your life.

　　Does the city provide 24-hour emergency alerts? What if an evacuation order goes out, but it's 3 a.m. and you're sound asleep? Not a problem if your city has a way of alerting you at any time of day. Some rely on street sirens(警报器)to do the trick. Others have used their websites to invite residents to sign up for e-mail notifications or automated phone calls in an emergency.

　　Medical Response

　　Are there at least 500 hospital beds for every 100,000 residents? Getting to victims quickly is a critical first step. But you'd better have a place to take them for treatment. A reasonable standard, according to preparedness experts, is 500 hospital beds for every 100,000 people—a ratio that would likely mean a city could find enough spare beds in an emergency. Of course, beds alone won't s help a massive number of burn victims or people suffering from chemical exposure unless the hospital is prepared to treat them. But all the cities in our survey have specialty units in their hospitals that can handle such cases.

　　Are local teams trained to respond quickly and work together? If and urban area was targeted by weapons of mass destruction, city health officials couldn't just wait for federal help to arrive. First responders and hospital would need to react right away. They could also need medical volunteers—say, to help vaccinate people or distribute medicines and supplies. How to ensure that all these professionals and volunteers work together as seamlessly as possible? If a city is part of DHS's Metropolitan Medical Response System, it has obtained federal assistance in developing plans, and has received critical training and equipment.

　　Are there labs nearby that specialize in biological and chemical threats? The CDC is on the cutting edge with its Laboratory Response Network—integrated labs nationwide that have the equipment and expertise to quickly identify pathogens and toxic chemicals. An LRN lab in Florida was the first to detect anthrax(炭疽热)in terrorist mailings in 2001. Laboratories can be members only if they have highly trained staff and exceptional facilities, as well as track record of testing accuracy. A handful of LRN labs qualify as "Level 1", meaning they can test for chemical poisons such as mustard and nerve agents.

　　1. A bird flu, a massive earthquake, a monster storm and a terrorist attack are all threats to major cities in the U.S.

　　2. The author does an assessment of all high-risk urban areas in the U.S.

　　7. Incompatible communications is a country-wide problem in the U.S. because of the ________ which should be converted or replaced.
