单选题{{B}}第三篇{{/B}} {{B}} Online Cancer Chat with a Safety Net{{/B}} Cancer Research UK has launched an online chat forum for cancer patients to swap stories and share experiences on how to cope with such a devastating disease. But Cancer Chat is a forum with a difference: it has an information safety net. This means that a Cancer Research UK team will keep a watching brief to ensure that patients are not subjected to rogue "cancer cures" or scientifically unsound information. Anyone can have access to the messages posted on Cancer Chat but if people wish to post a message they will need to register. And Rebekah Gibbs, cancer patient and star of TV's Casualty has pledged her support for the new project. "I think Cancer Chat is a brilliant idea," she said. "I have written a public diary about what I went through with breast cancer and I have had such a heart-warming response from other people going through the same thing. "The idea of a Cancer Chat forum means you can share information about treatment and side effects and you can really open up about your feelings online in a way that can be difficult when talking to close friends and family. And with Cancer Research UK monitoring the forum people can be reassured about the quality of information being exchanged." Cancer Chat will also encourage its users to check out any cancer questions on its CancerHelp UK website which is specially designed to give patients and their families 6,000 pages of up-to-date information that is easy to understand and explains a wide range of treatments for different types of cancer and gives details of clinical trials. There is also a UK database of cancer clinical trials. The award-winning website attracts around one million visitors a month and Cancer Research UK hopes that some of these visitors will also want to post comments on the Cancer Chat forum. For those who do not have access to computers and have questions about cancer, the charity's team of cancer information nurses are available during office hours to talk over patients' concerns on the phone.

The experts say HIV has an almost perfect ability to avoid the body's immune (免疫的) defenses, making it ideal for carrying replacement genes into patients' bodies, according to the Observer. A team at the California-based Salk Institute, one of the world's leading research centers on biological sciences, has created a special new breed of HIV and has started negotiations with the U.S. Food and Drug Administration (FDA) to begin clinical gene therapy (治疗) trials this year. The first trials are expected to involve patients suffering from cancers that cannot be cured by surgery although project leader Professor Inder Verma said the HIV technique would have "far wider applications". The plan remains very likely to cause controversy since it involves making use of a virus which has caused more than 22 million deaths around the world in the past two decades. Verma said that the idea of using HIV for a beneficial purpose was "shocking" but the fierce nature of HIV had disappeared by having all six of the potentially deadly genes removed. Illnesses such as various cancers are caused when a gene in a patient's body fails to work properly. In the past two years, breakthroughs in genetics (遗传学) have led gene therapy scientists to try and replace the genes that do not function normally. Unfortunately, the body's immune defenses have been known to attack the modified genes and make them lose their effects before they can start their task and progress in the field has been held up by the lack of a suitable carrier. The HIV virus has the ability to escape from, and then destroy, the immune defense cells designed to protect our bodies and this makes it attractive to scientists as a way of secretly conveying replacement genes into patients' bodies.

"Many men actually do experience domestic violence, although we don't hear about it{{U}} (52) {{/U}}," Dr. Robert J. Reid of the University of Washington in Seattle, one of the study's authors, told Reuters Health. "They often don't tell{{U}} (53) {{/U}}we don't ask. We want to get the message out to men who{{U}} (54) {{/U}}experience domestic violence that they are not alone and there are resources available to{{U}} (55) {{/U}}." The researchers asked study participants about physical abuse and non-physical{{U}} (56) {{/U}}such as threats that made them{{U}} (57) {{/U}}for their safety, controlling behavior (for example, being told who they could associate with and where they could go), and constant name-calling. Among men 18 to 54 years old, 14.2 percent said they had experienced intimate partner{{U}} (58) {{/U}}in the past five years, while 6.1 percent reported domestic violence in the previous year. Rates were lower for men 55 and{{U}} (59) {{/U}}, with 5.3 percent reporting violence in the past five years and 2.4 percent having experienced it in the past 12 months. Overall, 30. 5 percent of men younger than 55 and 26.5 percent of older men said they had been victims of{{U}} (60) {{/U}}violence at some point in their lives. About half of the violence the men{{U}} (61) {{/U}}was physical. However, the physical violence men reported wasn't as harsh as{{U}} (62) {{/U}}suffered by women in a previous study; 20 percent to 40 percent of the men rated it as severe, compared to 61 percent of{{U}} (63) {{/U}}. Men who reported experiencing domestic violence had more emotional and mental health problems{{U}} (64) {{/U}}those who had not, especially older men, the{{U}} (65) {{/U}}found.

What is the missing element that our theories don't yet {{U}}(51) {{/U}} for? The answer is simple: People read newspaper stories {{U}}(52) {{/U}} a reason to learn more about what they are interested in. Computers, on the other hand, don't. In fact, computers don't {{U}}(53) {{/U}} have interests; there is nothing in particular that they are trying to find out when they read. If a computer {{U}}(54) {{/U}} is to be a model of story understanding, it should also read for a "purpose". Of course, people have several goals that do not make {{U}}(55) {{/U}} to attribute to computers. One might read a restaurant guide in order to satisfy hunger or entertainment goals, or to {{U}}(56) {{/U}} a good place to go for a business lunch. Computers do not {{U}}(57) {{/U}}, and computers do not have business lunches. However, these physiological and social goals give {{U}}(58) {{/U}} to several intellectual or cognitive(认知的) goals. A goal to satisfy hunger gives rise to goals to find {{U}}(59) {{/U}} about the name of a restaurant which serves the desired type of food, how expensive the restaurant is, the {{U}}(60) {{/U}} of the restaurant, etc. These are goals to {{U}}(61) {{/U}} information or knowledge, what we are calling {{U}}(62) {{/U}} goals. These goals can be held by computers too a computer might "want" to find out the location of a restaurant, and read a guide in order to do so {{U}}(63) {{/U}} the same way as a person might. While such a goal would not {{U}}(64) {{/U}} out of hunger in the case of the com puter, it might {{U}}(65) {{/U}} rise out of the "goal" to learn more about restaurants.
