1、他对伯尔赫斯弗雷德里克斯金纳所著口语行为的评论,也有助于发动心理学的认知革命,挑战1950年代研究人类行为和语言方式中占主导地位的行为主义。他所采用以自然为本来研究语言的方法也大大地影响了语言和心智的哲学研究。他的另一大成就是建立了乔姆斯基层级:根据“文法生成力”不同而对形式语言做的分类。正是在此期间,乔姆斯基开始更加公开地参与政治。随着他1967年在纽约书评上发表的一篇题为知识分子的责任的文章,乔姆斯基成为越南战争的主要反对者之一。从那时起,乔姆斯基便因他的政治立场而出名,对世界各地的政局发表评论,并撰写了大量著作。他对美国外交政策及美国权力合法性的批判影响深远,并因而成为富有争议的人物。他
2、有左派的忠诚追随者,但也受到右派及自由派越来越多的批评,尤其是针对他对911事件的反应。对美国外交政策的批评给乔姆斯基带来了人身威胁。他的名字被列在特奥多卡克辛斯基(Theodore Kaczynski,邮箱炸弹杀手)的预定名单上。在卡氏被捕以前,乔姆斯基让人检查收到的邮件以防炸弹。他自称也经常被警察保护,特别是在麻省理工校园的时候,虽然他本人原则上不同意这种保护。尽管对美国百般批评,乔姆斯基还是生活在美国。他的解释是:美国仍然是世界上最伟大的国家。后来他又阐发为:国与国之间的综合比较没有什么意义,我也不会这么比较。不过美国有些成就,特别是在言论自由方面几个世纪来争得的领先地位,是值得敬仰的。

15、hat children learn language in five stages, which arent clearly defined and some tie in with each other.These stages are:Stage One:This is where children say things for three purposes:1.To get something they want2.To get someones attention3.To draw attention to somethingThen they begin to make basic
16、 statements such as “daddy car”During this stage children begin naming things with single words and then move on to relating objects with other things, places and people, for example, “there mummy”. They also relate objects with events, for example, “bird gone”.At this early stage they dont have muc
17、h vocabulary so they use intonation to ask a question. Children use words like: “there, want and allgone” to express a full sentence. This could be said that part of this stage is holophrastic.Stage Two:This is when children usually ask questions, “where” questions come first. Their questions often
18、begin with interrogative pronouns (what, where) followed by a noun or verb such as “where gone?Children become concerned with naming and classifying things by frequently asking “Wassat?” They may also begin to talk about the characteristics of things for example: big/small. Children are taught to le
19、arn things in opposite pairs such as up/down and hot/cold. Stage Three:By now children would be asking lots of different questions but often signalling that they are questions with intonation alone, for example: “Sally play in garden mummy?” This is made into a question by varying the tone of voice.
20、Children soon begin to express more complex wants by using more grammatically correct language, for example: “I want mummy to take it work” meaning “I want mummy to take it to work” Verbs such as “listen” and “know” are also used. Children refer to events in the past and less often in the future. Th
21、ey usually talk about continuing action for examples: “she still in bed” and ask about the state of actions (whether something is finished or not)The basic sentence structure has expanded such as: subject+verb+object+adverb or any other element used Sentences like: “You dry hands” and “A man dig dow
22、n there” begin to appear and auxiliary verbs are used in sentences such as “I am going” and phrases like “on the table” preposition+article+nounStage Four:This is when children use increasingly complex sentence structures and begin to:Explain thingsAsk for explanations using the word: “why?Making a
23、wide range of requests: “shall I do it?Now they are able to use complex sentence structures they have flexible language tools for expressing a wide range of meanings. Probably the most remarkable development is their comprehension of language and use of abstract verbs for example “know” to express m
24、ental operations. They begin to communicate meaning indirectly by replacing imperatives such as “give me” with questions; “can I have?As well as saying what they mean they now have pragmatic understanding and suit their utterances to context or situation. Children also use negation (denial/contradic
25、tion) for example: “he doesnt want one!” They dont rely on intonation and signals anymore as they explain more fully.They are now able to use auxiliary verbs and may duplicate modal verbs “please, can I, may I” This could be showing that “may” is required for courtesy whilst “can” indicates being ab

They give information, asking and answering questions, requesting directly and indirectly, suggesting, offering, stating and expressing.Children are now able to talk abo
27、ut things hypothetically and conditionally for example “If I were you, I would” They are now able to explain conditions required for something to happen; “Youve got turn the tap on first in order to wash your hands” As well as making general references to past and future, children now talk about par
28、ticular times such as: “after tea” and “before bedtime” By this stage children are very comfortable with all questions beginning with words like: “What?” and “When?” where the subject and verb are reversed such as “what does that mean?” 乔姆斯基认为小孩生来就有能力学习任何人类语言之二ScriptsStage 1: Allgone!Mother: Yes, th
