单选题A number of researchers have examined the variables/strategies that affect students' learning English as a second language. This report identifies some of the learner variables/strategies used by two students in a Hong Kong Technical Institute. The instruments for data collection included observation, interviews and questionnaires. The findings are discussed and some implications highlighted. What makes a "good" language learner "good", and what makes a "poor" language learner "poor"? What does this imply for the teaching of language in the Hong Kong context? These are the central questions of this assignment. The existing body of research attributes the differences between language learners to learner variables and learner strategies, learner variables include such things as differences in personality, motivation, style, aptitude and age (Ellis, 1986: chap 5) and strategies refer to "techniques, approaches, or deliberate actions that students take in order to facilitate the learning and recall of both linguistic and content area information" (Chamot, 1987: 71). It is important to note here that what we are considering is not the fact that language learners do and can learn, but why there should be such variations in speed of learning, ability to use the target language, and in achieving examination grades, areas which generally lead to the classification of students as being either "good" or "poor". Learner variables and strategies have been the focus of a number of research projects, (O'Malley et al, 1985, Oxford, 1989). However, to the best of my knowledge, this area has not been researched in Hong Kong classrooms. Since I am a teacher of English working in Hong Kong, gleaning a little of what learner variables and strategies seem to work for local students seems to be a fruitful area of research. In discussing learner variables and strategies, we have to keep in mind the arbitrary nature of actually identifying these aspects. As the existing research point out, it is not possible to observe directly qualities such as aptitude, motivation and anxiety. (Oxford, 1986). We cannot look inside the mind of a language learner and find out what strategies, if any, they are using. These strategies are not visible processes. Also, as Naiman and his colleagues (1978) point out, no single learning strategy, cognitive style or learner characteristic is sufficient to explain success in language learning. The factors must be considered simultaneously to discover how they interact to affect success of failure in particular language learning situation. Bearing these constraints in mind, the aim of this assignment is to develop two small scale studies of the language learners attempting to gain an overall idea of what strategies are in use and what variables seem to make a difference to Hong Kong students.

单选题 Saying they can no longer ignore the rising prices of health care, some of the most influential medical groups in the nation are recommending that doctors weigh the costs, not just the effectiveness of treatments, as they make decisions about patient care. The shift, little noticed outside the medical establishment but already controversial inside it, suggests that doctors are starting to redefine their roles, from being concerned exclusively about individual patients to exerting influence on how healthcare dollars are spent. In practical terms, the new guidelines being developed could result in doctors choosing one drug over another for cost reasons or even deciding that a particular treatment—at the end of life, for example—is too expensive. In the extreme, some critics have said that making treatment decisions based on cost is a form of rationing. Traditionally, guidelines have heavily influenced the practice of medicine, and the latest ones are expected to make doctors more conscious of the economic consequences of their decisions, even though there's no obligation to follow them. Medical society guidelines are also used by insurance companies to help determine reimbursement (报销) policies. Some doctors see a potential conflict in trying to be both providers of patient care and financial overseers. 'There should be forces in society who should be concerned about the budget, but they shouldn't be functioning simultaneously as doctors,' said Dr. Martin Samuels at a Boston hospital. He said doctors risked losing the trust of patients if they told patients, 'I'm not going to do what I think is best for you because I think it's bad for the healthcare budget in Massachusetts.' Doctors can face some grim trade-offs. Studies have shown, for example, that two drugs are about equally effective in treating macular degeneration, and eye disease. But one costs $50 a dose and the other close to $2000. Medicare could save hundreds of millions of dollars a year if everyone used the cheaper drug, Avastin, instead of the costlier one, Lucentis. But the Food and Drug Administration has not approved Avastin for use in the eye, and using it rather than the alternative, Lucentis, might carry an additional, although slight, safety risk. Should doctors consider Medicare's budget in deciding what to use? 'I think ethically (在道德层面上) we are just worried about the patient in front of us and not trying to save money for the insurance industry or society as a whole,' said Dr. Donald Jensen. Still, some analysts say that there's a role for doctors to play in cost analysis because not many others are doing so. 'In some ways,' said Dr. Daniel Sulmasy, 'it represents a failure of wider society to take up the issue.'
