新gre作文备考:十大论证技巧.

刚刚更新 编辑: 浏览次数:274 移动端

  新gre作文题目更加具体,考察考生时是否能够融合评判性思维和分析写作能力,每个人的新gre作文论述观点各不相同,那新gre论证技巧你掌握多少?下面是十大论证技巧介绍:

  GRE作文中观点可以因人而异,论据可以千差万别,但论证技巧却几乎就那些。最近在看《新GRE作文5.5》,这本书写得还行吧,我接下来会摘录一些段落篇章,和大家分享,也算是一个读书笔记。有些地方我不认同,也希望大家欢迎指正!

  一、演绎推理论证法

  将一个具体的事例运用到一个一般性原则从而得出结论。

  论点:Demand for this product wii go up。

  论据:The price of the product is sliding.

  推理依据:Whenever prices of a product go down , demand for it rises.

  (说明:由论据“the price of the product is sliding ”推出论点“Demand for this product will go up”,这个过程是否有效取决于推理依据“whenever prices of a product go down , demand for it rises”是否成立。下面每一种论证方法都是如此)

  二、定义法

  界定一个概念的关键内涵;或者认定某个事物符合某个定义,从而得出结论。例如:

  论点:Radical feminists are not good citizens.

  论据:Radical feminists lack family values.获得更多gre考试咨询点击进入>>>>澳际免费咨询顾问或联系QQ客服:

  三、因果关系论证法

  将一个判断放入一个因果关系中,指出它或者是原因,或者是结果。例如:

  论点:The internet may be causing depression.

  论据:When a group of people increased their use of the Internet , they felt depressed.

  推理依据:There are no other reasons for the group&aposs depression.

  四、归纳推理论证法

  从若干个具体事例中推出共性的一般结论。如:

  论点:Everyone likes the movie.

  论据:I know three people who like the movie.

  推理依据:Three eaxmples are enough.

  五、列举特征式论证法

  指出某事物发生或者生存的征候或者迹象。例如:

  论点:The child has chickenpox.

  论据:The child has red spots.

  推理依据:These spots are signs of chickenpox.

  六、类比论证法

  用我们已知的、熟悉的事物同未知的。不熟悉的事物加以比较,并用前者的情况解释者 的情况。分为三种:纵向类比(过去的事物同现在的、同一类事物的类比)、横向类比(同一 时期、同一事物之间的类比)、比喻式类比(不同类别事物之间的类比)。例如:

  1.纵向类比(Historical analogy)

  论点:Many people will die of SARS.

  论据:Many people died of the Black Death.

  推理依据:SARS and Black Death are similar.

  2.横向类比(Literal analogy)

  论点:China should have its fighter carriers.

  论据:A neighboring country has a powerful carrier fleet.

  推理依据:The two countries are similar enough to draw such a comparison.

  3.比喻式类比(Metaphorical analogy)

  论点:Reading a difficult book should take time.

  论据:Digesting a large metal takes time.

  推理依据:Reading and eating are sufficiently alike to be compared.

  七、引用权威论证法

  引用公认的权威,或者论证自己就是权威从而对自己的观点加以论证。例如:

  论点:China&aposs economy will grow 8 poercent this year.

  论据:Professors and scientists say so.

  推理依据:These experts are reliable.

  八、诉诸尝试法

  利用人们的常识【包括:普遍的价值观念、人的普遍动机、生活常识】进行论证。例如:

  1.诉诸普遍性的价值观念。

  论点:The university curriculum should be multicultural.

  论据:A multicultural curriculum will contribute to equality and acceptance.

  推理依据:You value equality and acceptance.

  2.诉诸普遍动机

  论点:You should support this candidate premier.

  论据:The candidate can help you get job security and safe neighbourhoods.

  推理依据:You want job security and safe neighbourhoods.

  3.诉诸生活常识

  论点:She was very kind to me.

  论据:She treated me with the best tea she had.

  推理依据:A treatment with the best tea is an expression of kindness.

  九、反证法

  假设一个观点是正确的,然后却推导出荒谬的结论。例如:

  论点:An industrious man must also be thrifty.

  论据:With only industry but without thrift ,the person will end uo bankrupt.

  推理依据:An industrious person ending up bankrupt sounds absurd.

  十、统计数据论证法

  提供数据,以资论证。例如:

  论点:We should end the current poverty-reli program.

  论据:It costs $45 million per year.

  推理依据:This is too much;it proves we should end it.

  只是一个详细的结构上的分析说明,在具体运用时,我们经常讲推理依据和论据放在了一起,但只要合理即可。论据可以自己编造,也可以是大众的例子,关键在于自己怎么样建立论点和论据之间的桥梁。上面的这些技巧,可能我们只用到某种或某几种,但我们必须得会至少一种。

  以上即是新gre作文十大论证技巧介绍,考生可以根据以上论证技巧,选择一个适合自己的新gre作文写作论证技巧,掌握了写作技巧才能更好的应对新gre写作。
