【正确答案】I think the reason for this misuse can be explained with the structuralist view toward learning and error. The structuralist linguists follow the behavioristic view that to leam is to change otd habits and build new habits. In their opinion, errors occur when the learner fails to respond correctly to a particular stimulus in the second language because the features of the second language differ from those of the native language and the learner tends to carry over features of the native language into the second language. In other words, the learner fails to change his old habits so as to acquire new habits of the second language. Since an error may serve as a negative stimulus which reinforces "bad habits", so it should not be allowed to occur. Therefore, the student uses the structure incorrectly in spontaneous speech because he doesn't form the English habits to use indirect questions with the influence of his native-language habits. The drill practice, based on the structuralist view, is an effective technique in language teaching to some extent although it has its disadvantages. Drill practice may be views as a kind of input and it plays an important role in the process of forming a new habit. Therefore, the lesson was not a waste of time. But pattem drill is performed out of real situation and fails to develop students'communicative competence. In the lesson, teachers may combine some approaches, such as communicative approach, grammar-translation approach, direct approach, audio-lingual approach and natural approach.
