4. Intricately intertwined with(与……错综交织) self-esteem and inhibition and risk-taking, the construct of anxiety, as it has been studied in the psychological domain(领域), plays an important affective role in second language acquisition. Anxiety is almost impossible to define in a simple sentence. It is associated with feelings of uneasiness, frustration, self-doubt, apprehension(恐惧), or worry. Scovel defined anxiety as “state of apprehension, or vague fear…” We all know what anxiety is and we all have experienced feelings of anxiousness. How does this construct relate to second language learning? Any complex task we undertake can have elements of anxiety in it, aspects in which we doubt our own abilities and wonder if we will indeed succeed. Second language learning is no exception to a long list of complex tasks that are susceptible(易受感染的) to our human anxieties.The research on anxiety suggests that, like self-esteem, anxiety can be experienced at various levels. At the deepest, or global level, trait anxiety is a more permanent predisposition(倾向) to be anxious. Some people are predictably and generally anxious about many things. At a more momentary, or situational level, state anxiety is experienced in relation to some particular event or act. As we learned in the case of self-esteem, then, it is important in a classroom for a teacher to try to determine whether a student’s anxiety stems from a more global trait or whether it comes from a particular situation at the moment.Trait anxiety, because of its global and somewhat ambiguously defined nature, has not proved to be useful in predicting second language achievement. However, recent research on foreign language anxiety, as it has come to be known, focuses more specifically on the situational nature of state anxiety.(5分)4.1 The passage mainly talks about ______.(1分)A. anxietyB. inhibitionC. risk-takingD. self-esteem

22.There is no doubt that new technologies will also play an important role in language teaching in the twenty-first century. Indeed, the use of technology in foreign language learning has constituted another important revolutionary movement in our discipline (学科）in the last half of the twentieth century. Although it has clearly not been a methodological revolution，technological innovation has played an important role in the recent history of language teaching and is bound to have a profound effect on the way that languages are taught in the future. Beginning with the introduction of filmstrips, audiotapes, and language labs in “direct method” and “audiolingual” classroom over forty years ago, technological innovation has moved from the increased use of cassette tapes, videotapes, and overhead projectors and cameras in the past several decades to the introduction of CD-ROMs and the Internet in the 1990s. The possibilities for computer-enhanced language teaching have most recently been explored in distance education programs as well as in the use of local area networks, computer-assisted reading programs, and web-based classroom activities.Though the use of technology is nothing new in foreign language teaching, its exact role in the curriculum is still being assessed and questioned, particularly in light of the rapidly changing nature of technological aids to instruction. Rather than seeing technology as just another ancillary (助手） to be added to our teaching devices, we need to evaluate its potential for enhancing classroom learning as well as for facilitating (使……便利）student-centered, independent learning outside the classroom. In using technological aids and computer-mediated (计算机为中介的）materials in instruction, we also need to bear in mind the level of proficiency of our students and their ability to benefit from the materials that can be used for them. The use of authentic materials is going to be discussed in more detail in a later section of this chapter and in subsequent chapters.(10分)22.1 This passage is mainly about____.(2分)A. the role technology plays in foreign language learningB. the role technology plays in foreign language teachingC. the role computer plays in language learning and language teachingD. the role technology plays in foreign language learning and teaching
