这种观点认为无论学习什么都是从技能或行为相关的 陈述 知识发展 最终达到程序性知识的自动化 2 TheNaturalOrderHypothesis 2 1Secondlanguagelearnersseemtoacquirethefeaturesofthetargetlanguageinpredictablesequence

makingminorchangesandpolishingwhattherequiredsystemhasproduced Itmayhappenbeforeactuallyspeakorwrite oritmayhappenlater 学习者用母语表达时可以脱口而出 不假思索 但是用第二语言表达时人们会经常不自觉地留意自己的语言是够正确 这种 注意 或 留心 其实就是 监控 的过程 例如 当英语学习者说 HewenttoBeijingyesterday 时 表达意思所需要的就是语言知识来自于 习得 系统 而 学习 中的知识所起到的作用是检查 he 是不是合适的代词 went 的时态是否正确 3
