单选题What are the chances that we will encounter some alien form of life, as we explore the galaxy. If the argument about the time scale for the appearance of life on Earth is correct, there ought to be many other stars, whose planets have life on them. Some of these stellar systems could have formed 5 billion years before the Earth. So why is the galaxy not crawling with self designing mechanical or biological life forms? Why hasn't the Earth been visited, and even colonized. I discount suggestions that UFOs contain beings from outer space. I think any visits by aliens would be much more obvious, and probably also, much more unpleasant. What is the explanation of why we have not been visited? One possibility is that the argument about the appearance of life on Earth is wrong. Maybe the probability of life spontaneously appearing is so low that Earth is the only planet in the galaxy, or in the observable universe, in which it happened. Another possibility is that there was a reasonable probability of forming self-reproducing system, like cells, but most of these forms of life did not evolve intelligence. A third possibility is that there is a reasonable probability for life to form, and to evolve to intelligent beings, in the external transmission phase. But at that point, the system becomes unstable, and the intelligent life destroys itself. This would be a very pessimistic conclusion. I very much hope it isn't true. I prefer a fourth possibility: there are other forms of intelligent life out there, but we have been overlooked. There used to be a project called SETI, the search for extraterrestrial intelligence. It involved scanning the radio frequencies, to see if we could pick up signals from alien civilizations. I thought this project was worth supporting, though it was cancelled due to a lack of funds. But we should have been wary of answering back, until we have developed a bit further. Meeting a more advanced civilization, at our present stage, might be a bit like the original inhabitants of America meeting Columbus. I don't think they were better off for it.

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" (Chabot, 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 points 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 affect success or 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 交谈话题 在中国，人们见面时喜欢问：“你去哪儿?”或“你吃了吗?”大多数时候，人们并非真正想知道你要去哪里或吃饭了没有。实际上，那只是一种打招呼的方式。与西方的风俗相似，当你与一个陌生人开始交谈时，诸如天气、食物或爱好之类的话题可能是打破坚冰的不错选择。询问私人问题时应当慎重，但是聊些关于家乡、工作方面的话题则通常可以使谈话顺利进行。
