【正确答案】Besides input, output has also been reported to promote language acquisition. Correct production requires learners to construct language for their messages. When learners construct language for expression, they are not merely reproducing what they have learned. Rather they are processing and constructing things. For example, they process syntax read or heard and construct syntax that can be used to express that they wish to convey.
The conception of language output as a way to promote language acquisition is to some extent in line with the so called constructivism. A constructivist view of language argues that language (or any knowledge) is socially constructed. Learners learn language by cooperating, negotiating and performing all kinds of tasks. In other words, they construct language in certain social and cultural contexts.
The type of language constructed by second or foreign language learners who are still in the process of learning a language is often referred to as interlanguage. Interlanguage is often understood as a language system between the target language and the learner's native language. It is not imperfect compared with the target language, but it is not mere translation form the native language either. However, interlanguage should not really be seen as a bridging language between or a mixture of the target language and native language. Therefore, "inter" actually means between the beginning stage and the final stage.
Studies on interlanguage can be done in two ways: (1)investigating the psychological, biological or neurological mechanisms involves in production of interlanguage; (2)investigating the linguistic features of interlanguage. Concerning the linguistic features of interlanguage, the following questions can be asked:
1)Linguistically, how is interlanguage in general different form the target language or the native language?
2)In what way is lower level interlanguage different from higher level interlanguage?
3)How is the interlanguage system used to convey meaning?
Answers to the above questions will certainly benefit language learning research.
According to your own experiences, please talk about how the interlanguage works in your foreign language learning process.

【答案解析】[解析] 本题考查中介语和语言学习的相关知识，建构主义的语言观认为，学习语言(或者任何其他知识)都是一个社会建构的过程。学习者们可以通过相互合作、协商和完成各种各样的任务来学习语苦。换句话说，他们在某种社会和文化环境下构建自己的语言。
