【正确答案】The Interaction Hypothesis, which was first advanced by Michael Long in early 1980s, is put forward as a further supplement or extension of the Input Hypothesis in the field of second language acquisition. It says that language acquisition requires or greatly benefits from interaction, communication and especially negotiation of meaning, which happens when interlocutors attempt to overcome problems in conveying their meaning, resulting in both additional input and useful feedback on the learner's own production.
It is quite obvious that the hypothesis has some important implications for the practice of language teaching. First of all, in his hypothesis, Long argues that greater attention should be paid to the interaction in which learners are engaged in order to understand more fully the nature and usefulness of input for second language acquisition. These interactions should not be seen simply as a one-directional source of target language input, feeding into the learner's presumed internal acquisition device. In fact, the more the input is queried, recycled and paraphrased, the greater its potential usefulness is input. This tells us clearly what we should do with interaction in teaching.
Second, Long places emphasis on the importance of the interactional modifications applied by both participants of the interaction, which he thinks promote the comprehension as well as the communication process. This means that teachers should call students' attention to the negotiation of meaning when in real communication.
In addition, in his point of view, interactive input is more important than non-interactive input. This means that in classroom teaching, teachers should try to interact with students and hence facilitating students' learning.
