单选题The first technological revolution in modern biology started when James Watson and Francis Crick described the structure of DNA half a century ago. That established the fields of molecular and cell biology, the basis of the biotechnology industry. The sequencing of the human genome nearly a decade ago set off a second revolution which has started to illuminate the origins of diseases. Now the industry is convinced that a third revolution is under way: the convergence of biology and engineering. A recent report from the Massachusetts Institute of Technology says that physical sciences have already been transformed by their adoption of information technology, advanced materials, imaging, nanotechnolugy and sophisticated modelling and simulation. Phillip Sharp, a Nobel prize-winner at that university, believes that those tools are about to be brought to bear on biology too. But the chances are that this will take time, and turn out to be more of a reformation than a revolution. The conventional health-care systems of the rich world may resist new technologies even as poor countries leapfrog ahead. There is already a backlash against genomics, which has been oversold to consumers as a deterministic science. And given soaring health-care costs, insurers and health systems may not want to adopt new technologies unless inventors can show conclusively that they will produce better outcomes and offer value for money. If these obstacles can be overcome, then the biggest winner will be the patient. In the past medicine has taken a paternalistic stance, with the all-knowing physician dispensing wisdom from on high, but that is becoming increasingly untenable. Digitisation promises to connect doctors not only to everything they need to know about their patients but also to other doctors who have treated similar disorders. That essential reform will enable many other big technological changes to be introduced. Just as important, it can make that information available to the patients too, empowering them to play a bigger part in managing their own health affairs. This is controversial, and with good reason. Many doctors, and some patients, reckon they lack the knowledge to make informed decisions. But patients actually know a great deal about many diseases, especially chronic ones like diabetes and heart problems with which they often live for many years. The best way to deal with those is for individuals to take more responsibility for their own health and prevent problems before they require costly hospital visits. That means putting electronic health records directly into patients’ hands.

单选题In recent years American society has become increasingly dependent on its universities to find solutions to its major problems. It is the universities that have been charged with the principal responsibility for developing the expertise to place men on the moon; for dealing with our urban problems and with our deteriorating environment; for developing the means to feed the world's rapidly increasing population. The effort involved in meeting these demands presents its own problems. In addition, this concentration on the creation of new knowledge significantly impinges on the universities' efforts to perform their other principal functions, the transmission and interpretation of knowledge the imparting of the heritage of the past and the preparing of the next generation to carry it forward. With regard to this, perhaps their most traditionally sanctioned task, colleges and universities today find themselves in a serious hind generally. On the one hand, there is the American commitment, entered into especially since WW 1I, to provide higher education for all young people who can profit from it. The result of the commitment has been a dramatic rise in enrollments in our universities, coupled with a radical shift from the private to the public sector of higher education. On the other hand, there are serious and continuing limitations on the resources available for higher education. While higher education has become a great "growth industry", it is also simultaneously a tremendous drain on the resources of nation. With the vast increase in enrollment and the shift in priorities away from education in state and federal budgets, there is in most of our public institutions a significant decrease in per capita outlay for their students, one crucial aspect of this drain on resources lies in the persistent shortage of trained faculty, which has led, in rum, to a declining standard of competence in instruction. Intensifying these difficulties is, as indicated above, the concern with research, with its competing claims on resources and the attention of the faculty. In addition, there is a strong tendency for the institutions; organization and functioning to conform to the demands of research rather than those of teaching.

单选题The moral high ground has always been female territory. Men, after all, lie and cheat and rob and pollute the environment and disproportionately populate the prisons, while women do their best to appreciate their good qualities. Some women, at least. But with the rise of feminism, the assaults on men's moral probity have become more frequent, and the belief in their arrogance and lack of concern for anything but their own selfish ends has become a truism. It's the men who are greedy. It's the men who are disloyal. It's the men who will do anything for money. It's the men who are immature. In the world of sport, pouty male athletes are Whipping boys of talk radio. They have graced the cover of Sports Illustrate, and on the inside have been vilified for a litany d sins, among them greed, disdain for the fans who pay their exorbitant salaries, and a lack of respect for the game that the fans love and that has made them rich. Female athletes, on the other hand, have been placed on a pedestal--but it has been a pretty easy one to climb. For one thing, there hasn' t been enough money to get greedy about. For another, there haven' t been any fans. And for third, those who didn't love the game had absolutely no reason to keep playing. But thanks to the rise of women' s basketball, female basketball players are going to find themselves tempted by the same vanities that have seduced so many men- and though we know some will give in, we don' t know how many. For women's basketball to become a major sport in America, as opposed to a profitable one like arena football, something is going to be offered other than just pure skill. That something should be, and if fact will have to be, a different attitude, a purer sense of sport, than the men deliver. It may be asking too much of women to withstand the temptations that have sucked male athletes into prima donna poses, but then again it may be true that women have occupied the high moral ground for so long because they actually are more sensitive to what's important in the long run. I honestly don' t know how this drama will play out, but the process will tell us about more than just the fate of women' s basketball. If women, who are steadily gaining more and more control in this world, 'can truly respond in a more reasoned way to the pull of power, then there is hope for the 21st century. But if women, as a gender, can do no hatter than men when given the chance, then in basketball as in life, we can only look ahead to more of the same.
