第20题: [简答题]Does it always matter if the "real world" is not being practised in the classroom Why or why not 参考答案:
The ideal language learning setting is to practise language as it is used in the real world.Since learners will have to use the foreign language in real communication outside the classroom. However, it is not always possible to do so because classroom setting is after all different from the outside world no matter how hard we try to simulate the real-world situation. And it is not always necessary to do so. Language learning and language teaching are considered at several stages. At the drilling stage, when the focus is on language form, the"real world" situation does not have to be practised. But when the focus is on language communication and learners are engaged in communicative activities, the "real-world" situation does matter much. It is where learners learn to use the foreign language for real communication, and to use it appropriately and accurately.
