GMAT邏輯題加強題解決辦法

Lawyer大神在邏輯聖經(就是把LSAT 的OG翻譯過來了而已。。。。)里問過這樣一個問題:「在考場里做邏輯題時是按平時分析題的思路去做題嗎?」 我個人的觀點是No, 很明顯在那樣一種題目壓力和時間壓力下,你是來不及做到把每一題都分析透徹的,在考場上做邏輯題,更多的是靠一種感覺,這種感覺和語法題做多所形成的「語法潔癖」是同類事物,而這種感覺怎麼形成了?

自然不是靠我們去猜,這裡我就大概說一說我對於這種感覺的理解, 首先看問題,看問題的目的在於(1)你知道這是一種什麼題型,是需要我們分清條件和結論(非MUST BE TRUE/CANNOT BE TRUE/RESOLVE THE DESCREPANCY題目)還是需要(MUST BE TRUE/CANNOT BE TRUE/RESOLVE THE DESCREPANCY),(2)你知道我們需要加強或者削弱的目標是什麼!!!

常規題會讓我們去削弱和加強結論,但是我是見過有讓我們去加強和削弱evidence的題目,而不是結論!!在條件結論題型下繼續確定這是加強題還是削弱體,是加強題立馬反應正確選項是要幫我們去證明結論(或者指定的那個部分)是對的,而削弱則是讓我們證明結論(或者指定的那個部分)是有問題。 之後開始梳理邏輯鏈 在腦中形成因為(直接前提)所以(結論)的推理結構。 梳理完畢,進入篩選選項階段,第一步 預測答案 比如讀出了文章當中有明顯的gap那麼答案一定會在這個gap上做文章,然而如果僅僅只能預測一個大概,首選有關無關進行排查, 我們說無關選項的特點一定是與原文當中條件 結論 以及他們之間所對應的影響關係 沒有半毛錢選項的 選項,他們可以很扯,不難判斷, 最後一步則是在幾個可疑的選項中進行比對。其實有很多題可以進行驗證以保證萬無一失,比如加強題的公式是(Premise+AC-Conclusion) 削弱體(Premise+AC 否定 Conclusion)或者Assumption里的取否削弱都是驗證最後答案的方法。

演示一題:

1.It is true of both men and women that those who marry as young adults live longer than those who never marry. This dose not show that marriage causes people to live longer, since, as compared with other people of the same age, young adults who are about to get married have fewer of the unhealthy habits that can cause a person to have a shorter life, most notably smoking and immoderate drinking of alcohol.

Which of the following, if true, most strengthens the argument above?

A. Marriage tends to cause people to engage less regularly in sports that involve risk of bodily harm.(思考,這句話和「不結婚也能使人活的長」之間有聯繫嗎?並沒有!)

B. A married person who has an unhealthy habit is more likely to give up that habit than a person with the same habit who is unmarried.(婚姻會讓人如何。。如何。。)

C. A person who smokes is much more likely than a nonsmoker to marry a person who smokes at the time of marriage, and the same is true for people who drink alcohol immoderately.(無關)

D. Among people who marry as young adults, most of those who give up an unhealthy habit after marriage do not resume the habit later in life. (婚姻會讓人如何如何)

E. Among people who as young adults neither drink alcohol immoderately nor smoke, those who never marry live as long as those who marry. (習慣好,即便不結婚也活得長,支持)

找出premise 和conclusion

A:準備結婚的男男女女有更少的不良習慣

B:並不是婚姻使人活得更長

我們一定要知道strengthen類型的題,它想支持的是作者的觀點,如果premise和conclusion沒有很強的因果關係,則立馬從選項里找一個能幫助作者說話或幫助作者證明結論的答案,也就是說找一個選項幫我們證明確實並不是婚姻使人活的很長
