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
