单选题The concept of "environment" is certainly difficult and may even be misunderstood; but we have no handy substitute. It seems simple enough to distinguish between the organism and the surrounding environment and to separate forces acting on an organism into those that are internal and biological and those that are external and environmental. But in actual practice this system breaks down in many ways, because the organism and the environment are constantly interacting so that the environment is modified by the organism and vice versa. In the case of man, the difficulties with the environmental concept are even more complicated because we have to deal with man as an animal and with man as a bearer (持有者) of culture. If we look at man as an animal and try to analyze the environmental forces that are acting on the or-ganism, we find that we have to deal with things like climate, soil, plants, and such-like factors common to all biological situations; but we also find, always, very important environmental in-fluences that we can only class as "cultural", which modify the physical and biological factors. But man, as we know him, is always a bearer of culture; and if we study human culture, we find that it, in turn, is modified by the environmental factors of climate and geography. We thus easi-ly get into great difficulties from the necessity of viewing culture, at one moment, as a part of the man and, at another moment, as a part of the environment.

单选题 In 2009 the European Commission carried out an investigation into Microsoft. The American software giant tied Internet Explorer, its web browser, into Windows, the operating system in the great majority of personal computers. This, thought the commission, might be an abuse of its dominance in operating systems: buy a PC, and unless you took the trouble of choosing otherwise, you would browse the web through Explorer. In December that year Microsoft promised that until 2014 it would provide a "choice screen", asking European Windows users whether they wanted to install another browser. The screen first turned up in March 2010. Jolly good—but Microsoft forgot to keep its word. On March 6th the competition commissioner, Joaquin Almunia, said he had fined it 561m ($732m) for not including the choice screen with 15m copies of Windows software between May 2011 and July 2012. Neither Microsoft nor the commission spotted the lapse. It seems that eventually other companies did. The fine must sting all the more because Microsoft's transgression brought it little if any gain. Explorer has fallen behind Chrome, made by Google, and Firefox, made by Mozilla, a non-profit organisation. And people are doing more and more browsing on smartphones and tablets, the domain of Apple, Google and their browsers. Microsoft's antitrust woes in Europe should have been over. In 2004 in was fined 497m for trying its media player and server operating systems with it PC system. In 2008 it copped another 899m penalty for failing to comply with the commission's ruling in that case. Lately it has been among the accusers—of Google, which Mr. Almunia has been investigating since 2010. He suspects Google of abusing a position in online search every bit as imposing as Microsoft's in PC operating systems. Bing, Microsoft's search engine, is a distant second. The commissioner believes that Google may be favouring its own specialised services at rival's expense; that its deals with publishers may unfairly exclude competitors; and that it prevents advertisers from taking their data elsewhere. Mr. Almunia asked Google to propose by the end of January ways of meeting his concerns. He has not yet said what it suggested or how he will respond. European antitrust cases have a habit of dragging on. Just ask Microsoft.

单选题George Mason must rank with John Adams and James Madison as one of the three Founding Fathers who left their personal imprint on the fundamental law of the United States. He was the principal author of the Virginia Declaration of Rights, which because of its early formation greatly influenced other state constitutions framed during the Revolution and, through them, the Federal Bill of Rights of 1791. Yet Mason was essentially a private person with very little inclination for public office or the ordinary operation of politics beyond the country level. His appearances in the Virginia colonial and state legislatures were relatively brief, and not until 1787 did he consent to represent his state at a continental or national congress or convention. Polities was never more than a means for Mason. He was at all times a man of public spirit, but politics was never a way of life, never for long his central concern. It took a revolution to pry him away from home and family at Gunston Hall, mobilize his skill and energy for constitutional construction, and transform him, in one brief moment of brilliant leadership, into a statesman whose work would endure to influence the lives and fortunes of those "millions yet unborn" of whom he and his generation of Americans spoke so frequently and thought so constantly.

单选题The mental health movement in the United States began with a period of considerable enlightenment. Dorothea Dix was shocked to find the mentally ill in jails and almshouses and crusaded for the establishment of asylums in which people could receive human care in hospital-like environments and treatment which might help restore them to sanity. By the mid 1800s, 20 states had established asylums, but during the late 1800s and early 1900s, in the face of economic depression, legislatures were unable to appropriate sufficient funds for decent care. Asylums became overcrowded and prison-like. Additionally, patients were more resistant to treatment than the pioneers in the mental health field had anticipated, and security and restraint were needed to protect .patients and others. Mental institutions became frightening and depressing places in which the rights of patients were all but forgotten. These conditions continued until after World War Ⅱ. At that time, new treatments were discovered for some major mental illnesses theretofore considered untreatable (penicillin for syphilis of the brain and insulin treatment for schizophrenia and depressions), and a succession of books, motion pictures, and newspaper exposés called attention to the plight of the mentally ill. Improvements were made and Dr. David Vail's Humane Practices Program is a beacon for today. But changes were slow in coming until the early 1960s. At that time, the Civil Rights movement led lawyers to investigate America's prisons, which were disproportionately populated by blacks, and they in turn followed prisoners into the only institutions that were worse than the prisons the hospitals for the criminally insane. The prisons were filled with angry young men who, encouraged by legal support, were quick to demand their rights. The hospitals for the criminally insane, by contrast, were populated with people who were considered "crazy" and who were often kept obediently in their place through the use of severe bodily restraints and large doses of major tranquilizers. The young cadre of public interest lawyers liked their role in the mental hospitals. The lawyers found a population that was both passive and easy to champion. These were, after all, people who, unlike criminals, had done nothing wrong. And in many states, they were being kept in horrendous institutions, an injustice, which once exposed, was bound to shock the public and, particularly, the judicial conscience. Patients' rights groups successfully encouraged reform by lobbying in state legislatures. Judicial interventions have had some definite positive effects, but there is growing awareness that courts cannot provide the standards and the review mechanisms that assure good patient care. The details of providing day-to-day care simply cannot be mandated by a court, so it is time to take from the courts the responsibility for delivery of mental health care and assurance of patient rights and return it to the state mental healty administrators to whom the mandate was originally given. Though it is a difficult task, administrators must undertake to write rules and standards and to provide the training and surveillance to assure that treatment is given and patient rights are respected.
