填空题 Translate the following into Chinese．(湖南大学2007研，考试科目：英语语言文学专业基础)The claim that technology-based approaches to language learning are supportive of autonomy rests in part on an assumption, shared with resource-based approaches, that they provide learners with opportunities to self-direct their own learning. In the case of CALL in particular, there is also an assumption that technology can provide learners with the kinds of support they need in order to develop skills associated with autonomy. This cannot be regarded as more than a potential, however, and a great deal depends on the ways in which technologies are made available to learners and the kinds of interaction that take place around them. In the case of CALL software, the degree of control offered to learners is often severely constrained by its structure and content. Text manipulation and computer-mediated communication applications offer greater opportunities for the development of control over learning content. They also offer opportunities for collaboration that are often lacking in other modes of self-access learning. But as in the case of self-access , it may be that learners require a degree of autonomy in advance in order to use new technologies effectively. Claims made for the potential of new technologies in regard to autonomy need to be evaluated against empirical evidence of the realization of this potential in practice.
