  具體實踐兩道題

  Teenagers are often priced out of the labor market by the government-mandated minimum-wage level because employers cannot afford to pay that much for extra help. Therore, if Congress institutes a subminimum wage, a new lower legal wage for teenagers, the teenage unemployment rate, which has been rising since 1960, will no longer increase.

  (注釋:priced out of the market:因價高而被擠出市場)

  Which of the following statements, if true, would most weaken the argument above?

  (A) Since 1960 the teenage unemployment rate has risen when the minimum wage has risen.

  (B) Since 1960 the teenage unemployment rate has risen even when the minimum wage remained constant.

  (C) Employers often hire extra help during holiday and warm weather seasons.

  (D) The teenage unemployment rate rose more quickly in the 1970’s than it did in the 1960’s.

  (E) The teenage unemployment rate has occasionally declined in the years since 1960.

  看完問題,發(fā)現(xiàn)是削弱題;再讀原文,意思不難,很快提煉出其邏輯為

  如果國會制定更低的teenagers最低工資 ===》teenagers的失業(yè)率將不再上升

  顯然,正確選項首先要涉及最低工資和失業(yè)率之間的關(guān)系,而其他內(nèi)容則為無關(guān)信息,可以排除

  顯然A 和B都是相關(guān)的

  而C在談季節(jié)問題,D和E沒有涉及失業(yè)率快慢的原因,都與原文邏輯無關(guān),通通排除。

  所以只需要仔細(xì)審視A和B

  A “最低工資上升的時候,失業(yè)率上升”,這與原文邏輯(更低工資將導(dǎo)致失業(yè)率不上升)形成了“反因反果”的關(guān)系,所以是加強。(比如:“不長跑的人不長壽”加強了“長跑的人長壽”)

  這樣A就被排除了

  所以答案只能是B

  在GMAT邏輯題目的解題過程中,考生除了要熟知一般的邏輯解題思路外,還需要靈活運用各種GMAT邏輯解題技巧,而這種技巧是考生在大量習(xí)題中培養(yǎng)起來的做題感覺??忌揽窟@種感覺可以快速將一些與題目無關(guān)的選項排除,從而找出正確答案。最后祝大家都能考出好成績。
