二语习得PPT整理二语习得一.二语习得概述(一)语言习得研究中的两个基本问题(1)逻辑问题(logical problem):语言习得是如何成为可能的?一个很有吸引力的推测是,儿童学会母语,是因为生活在母语环境中,每天接触母语所致。
但是,阿猫阿狗也接触人类语言,但没有一只猫、狗能学会人类语言。
这至少说明:A.接触语言是语言习得的必要条件,但并不是充分条件;B.在语言习得方面,人类似乎天生有一种其他动物没有的潜能。
There is a mismatch between the input (the utterance that the child is exposed to) and the output (the unconscious grammatical knowledge that the child acquires). This mismatch gives rise to what is known as the problem of the poverty of the stimulus(刺激贫乏)or the logical problem of language acquisition(语言习得逻辑问题). Given such underdetermination, the claim is that it would be impossible to acco unt for the L1 acquirers’ achievement without postulating a built-in system of universal linguistic principles and grammatical properties.(在语言习得方面,人类似乎天生有一种其他动物没有的潜能)(2)发展问题( developmental problem ):语言习得遵循一定的发展顺序和步骤。
