gre考試改革后，新gre作文題目更加具體，考察考生時(shí)是否能夠融合評(píng)判性思維和分析寫作能力，每個(gè)人的新gre作文論述觀點(diǎn)各不相同。下面是新GRE作文十大論證技巧介紹：

　　一、演繹推理論證法

　　將一個(gè)具體的事例運(yùn)用到一個(gè)一般性原則從而得出結(jié)論。

　　論點(diǎn)：Demand for this product wii go up。

　　論據(jù)：The price of the product is sliding.

　　二、定義法

　　論點(diǎn)：Radical feminists are not good citizens.

　　論據(jù)：Radical feminists lack family values.

　　推理依據(jù)：Family values characterize the good citizes.

　　三、因果關(guān)系論證法

　　論據(jù)：When a group of people increased their use of the Internet , they felt depressed.

　　推理依據(jù)：There are no other reasons for the groups depression.

　　推理依據(jù)：These spots are signs of chickenpox.

　　六、類比論證法

　　用我們已知的、熟悉的事物同未知的。不熟悉的事物加以比較，并用前者的情況解釋者 的情況。分為三種：縱向類比、橫向類比、比喻式類比。例如：

　　1.縱向類比

　　論點(diǎn)：Many people will die of SARS.

　　論據(jù)：Many people died of the Black Death.

　　推理依據(jù)：SARS and Black Death are similar.

　　2.橫向類比

　　論點(diǎn)：China should have its fighter carriers.

　　推理依據(jù)：The two countries are similar enough to draw such a comparison.

　　3.比喻式類比

　　論點(diǎn)：Reading a difficult book should take time.

　　論點(diǎn)：Chinas economy will grow 8 poercent this year.

　　論據(jù)：Professors and scientists say so.

　　推理依據(jù)：These experts are reliable.

　　八、訴諸嘗試法

　　利用人們的常識(shí)【包括：普遍的價(jià)值觀念、人的普遍動(dòng)機(jī)、生活常識(shí)】進(jìn)行論證。例如：

　　1.訴諸普遍性的價(jià)值觀念。

　　論點(diǎn)：The university curriculum should be multicultural.

　　論據(jù)：A multicultural curriculum will contribute to equality and acceptance.

　　推理依據(jù)：You value equality and acceptance.

　　2.訴諸普遍動(dòng)機(jī)

　　論點(diǎn)：You should support this candidate premier.

　　論據(jù)：The candidate can help you get job security and safe neighbourhoods.

　　論點(diǎn)：She was very kind to me.

　　論據(jù)：She treated me with the best tea she had.

　　推理依據(jù)：A treatment with the best tea is an expression of kindness.

　　九、反證法

　　假設(shè)一個(gè)觀點(diǎn)是正確的，然后卻推導(dǎo)出荒謬的結(jié)論。例如：

　　論點(diǎn)：An industrious man must also be thrifty.

　　論據(jù)：With only industry but without thrift ，the person will end uo bankrupt.

　　推理依據(jù)：An industrious person ending up bankrupt sounds absurd.

　　十、統(tǒng)計(jì)數(shù)據(jù)論證法

　　提供數(shù)據(jù)，以資論證。例如：

　　論點(diǎn)：We should end the current poverty-relief program.

　　論據(jù)：It costs $45 million per year.

　　推理依據(jù)：This is too much;it proves we should end it.

　　只是一個(gè)詳細(xì)的結(jié)構(gòu)上的分析說明，在具體運(yùn)用時(shí)，我們經(jīng)常講推理依據(jù)和論據(jù)放在了一起，但只要合理即可。論據(jù)可以自己編造，也可以是大眾的例子，關(guān)鍵在于自己怎么樣建立論點(diǎn)和論據(jù)之間的橋梁。上面的這些技巧，可能我們只用到某種或某幾種，但我們必須得會(huì)至少一種。

　　以上即是新gre作文十大論證技巧介紹，考生可以根據(jù)以上論證技巧，選擇一個(gè)適合自己的新gre作文寫作論證技巧，掌握了寫作技巧才能更好的應(yīng)對(duì)新gre寫作。
