For the past seven years, Milano—who describes himself as "a straight, white middle class married guy raised in an affluent suburb of Chicago"—as operated yforum.com, a Website that was created to get us talking. Through the posting of probing, provocative and sometimes simply inane questions and the answers they generate, people are encouraged to have a no-holds-barred exchange on topics across racial, ethnic and cultural lines. More often than not, the questions grow out of our biases and fears and the stereotypes that fuel misunderstanding among us. As with the Web site, Milano hopes his book will be a social and cultural elixir. "The time is right for a new ’culture of curiosity’ to begin to unfold, with people finally breaking down the last barrier to improve race and cultural relations" by actually talking to each other about their differences, Milano said in an e-mail message to me. Milano wisely used the Internet to spark these conversations. In seven years, it has generated 50,000 postings—many of them questions that people find hard to ask in a face-to-face exchange with the subjects of their inquiries. But in his book, which was published earlier this month, Milano gives readers an opportunity to read the questions and a mix of answers that made it onto his Web site. "I am curious about what people who have been blind from birth ’see’ in their dreams," a 13-year old boy wanted to know. "Why do so many mentally disabled people have such poor-looking haircuts and ’nerdy’ clothes？" a woman asked. "How do African-Americans perceive God？" a white teenager wanted to know. "Do they pray to a white God or a black God？" Like I said, these questions can generate a range of emotions and reactions. But the point of Milano’s Web site, and his book, is not to get people mad, but to inform. us "about the lives and experiences" of others. Though many of the answers that people offered to the questions posed in his book are conflicting, these responses are balanced by the comments of experts whose responses to the queries also appear in the book. Getting people to openly say what they are thinking about things that give rise to stereotypes and bigotry has never been easy. Most of us save those conversations for gatherings of people who look or think like us. The purpose of the website is to A．give people a chance to speak out. B．prepare materials for a book. C．get people exchanging ideas freely. D．solve the social and cultural problems.

Sweeping aside the doubts that many people feel about the benefits of new third generation phones and fears over the health effects of phone masts(天线竿),a recent report clains that the long-term effects of new mobile technologies will be entirely positive so long as the public can be convinced to make use of them.Research about users of mobile phones reveals that the mobile has already moved beyond being a mere practical communications tool to become the backbone (支柱)of modern social life,from love affairs to friendship to work.One female teacher,32,told the researchers:“I love my phone.It’s my friend.” The close relationship between user and phone is most pronounced among teenagers,the report says,who regard their mobiles as an expression of their identity.This is partly because mobiles are seen as being beyond the control of parents.But the researchers suggest that another reason may be that mobiles,especially taxt messaging,are seen as a way of overcoming shyness.“Texting is often used for apologies,to excuse lateness or to communicate other things that make us uncomfortable,”the report says,The impact of phones,however,has been local rather than global,supporting existing friendships and networks,rather than opening users to a new broader community.Even the language of texting in one area can be incomprehensible to anybody from another area. Among the most important benefits of using mobile phones,the report claims,will be a vastly improved mobile infrastructure(基础设施),providing gains throughout the economy,and the provision of a more sophisticated location-based services for users.The report calls on govemment to put more effort into the delivery of services by bobile phone,with suggestions including public transport and traffic information and doctors’ text messages to remind patients of appointments.“I love that idea,”one user said in an interview.“It would mean I wouldn’t have to write a hundred messages to myself.” There are many other possibilities.At a recent trade fair in Sweden,a mobile navigation product was launched.When the user enters a destination,a route is automatically downloaded to their mobile and presented by voice,pictures and maps as they drive.In future,these devices will also be able to plan around congestion(交通堵塞)and road works in real time.Third generation phones will also allow for remote monitoring of patients by doctors.In Britain scientists are developing a asthma(哮喘)management solution,using mobiles to detect early signs of an attack. 第11题：What does the writer suggest in the first paragraph about our attitudes to mobile phones？ A．We can’t live without them. B．We are worried about using them so much. C．We have contradictory feelings about them. D．We need them more than anything else to deal with modem life.

In passive sleep the body is at rest. We move very little. And the brain becomes very inactive, ff a person continues to sleep, she or he enters anew period, a more active period. The body goes through several changes: the brain temperature rises, blood in the brain increases, the body becomes very still and the brain goes into active state. And as the brain goes active, the eyes begin to move rapidly. And that is the sign of another change---the person is dreaming. Throughout the night, people alternate between passive and active sleep. Doctors have studied the sleep cycle and have found that everyone dreams---in fact, that everyone needs to dream in order to stay healthy. It appears we need both kind of sleep. We need passive sleep in order to rest our bodies. We need active sleep in order to dream. And dreaming helps us to rest our minds, What does not happen in the brain in the active sleep？ A．The brain becomes very active. B．The brain becomes very inactive. C．The brain temperature rises. D．The brain blood rises.

Many researchers believe that the presence of RNA in brain cells is the biochemical basis of memory; that is, the presence of RNA enables us to remember. Because certain chemicals are known to inhibit the synthesis of RNA in the body, we can test this hypothesis. Animals that have learned particular responses can be injected with an RNA inhibitor and then tested for memory of the learned responses. Which of the following test results would most seriously weaken the case for RNA as the basis of memory？ A．After an injection of RNA inhibitor, a wide range of behaviors in addition to the learned responses were affected. B．After an injection of RNA inhibitor, animals that had not consistently been giving the learned responses were able to give them consistently. C．After injections of RNA inhibitor, some animals lost memory of the learned responses totally but others lost it only partially. D．After a small injection of RNA inhibitor, animals responded well, but as the size of the injection increased, they gave fewer of the learned responses. E．After an injection of RNA inhibitor, animals could not learn a new response.

A．industry experience B．technical skills C．persoality traits D．core job behaviors
