单选题 {{B}}Questions 11-15 are based on the following passage.{{/B}} Among the many ways in which people communicate through speech, public speaking has probably received more study and attracted more attention than any other. Politicians campaigning for public office, salespeople presenting products, and preachers delivering sermons all depend upon this form of public communication. Even people who do not make speaking a part of their daily work are often asked to make public speeches: students at graduation, for instance, or members of churches, clubs, or other organizations. Nearly everyone speaks in public at some time or other, and those who perform the task well often become leaders. There are many reasons for speaking in public. A public speaker may hope to teach an audience about new ideas, for example, or provide information-about some topic. Creating a good feeling or entertaining an audience may be another purpose. Public speakers, however, most often seek to persuade an audience to adopt new opinions, to take certain actions, or to see the world in a new way. Public speakers usually know well in advance when they are scheduled to make an address. Consequently, they are able to prepare their message before they deliver it. Sometimes, though, speakers must deliver the message unprepared, or off the cuff, such as when they are asked to offer a toast at a wedding reception or to participate in a televised debate or interview. When they do not have to speak unprepared, most speakers write their own speeches. Politicians and business executives sometimes employ professional writers who prepare their speeches for them. These professional writers may work alone or in small teams. Although the speaker may have some input into the contents of the speech, the writers sometimes have a great influence over the opinions expressed by their employers. Regardless of how a speech is prepared, the person who delivers it is given credit for its effect upon its hearers.

单选题On February 10, the world of psychiatry will be asked, metaphorically, to lie on the couch and answer questions about the state it thinks it is in. For that is the day the American Psychiatric Association (APA) plans to release a draft of the fifth version of its Diagnostic and Statistical Manual of Mental Disorders (DSM-V). Mental illness carrying such stigma (~) as it does, and the brain being as little-understood as it is, revising the DSM is always a controversial undertaking. This time, however, some of the questions asked of the process are likely to be particularly probing. The DSM, the first version of which was published in 1952, lists recognized psychological disorders and the symptoms used to diagnose them. In the United States, what is in it influences whether someone will be diagnosed with an illness at all, how he will be treated if he is so diagnosed, and whether his insurance company will pay for that treatment. Researchers in other countries generally defer to the DSM, too, making the manual's definitions a lingua franca for the science of medical psychology. And, perhaps most profoundly, the DSM, then, is an important document. The APA has been working on the latest revision since 1999, and will not release the final version until May 2013. But some people are already accusing it of excessive secrecy and being too ambitious about the changes it proposes. Those critics will be picking over the draft next week to see if their fears have been realized. The original DSM reflected the "psychodynamic" view of mental illness, in which problems were thought to result from an interplay between personality and life history. (Think Freud, Jung and long hours recounting your childhood and dreams.) The third version, which was published in 1980, took a more medical approach. Mental illnesses were seen as distinct and classifiable, like physical diseases. DSM-Ⅲ came with checklists of symptoms that allowed straightforward, unambiguous diagnosis. Psychiatry began to seem less like an art form and more like a science. DSM-Ⅲ also introduced many more diagnoses than had appeared before. These included attention-deficit disorder, post-traumatic stress disorder and social phobia. In fact, the number of specific diagnoses more than doubled between DSM-Ⅰ and DSM-Ⅲ, from 106 to 265. DSM-IV, published in 1994, increased the number to 267, but left the underlying model alone.
