新SAT語法圖表題如何解題?

  24. Which choices offers an accurate interpretation of the data in the chart?

  A) two years or less of sea otters can completely eliminate sea urchins

  B) even two years or less of sea otter presence can reduce the sea urchin threat

  C) kelp density increases proportionally as sea urchin density increases

  D) even after sea otters were present for ten years or more, kelp density was still lower than sea urchin density

  答案: B

  答案解析:首先看圖表部分的小圖表,可得出深色陰影部分代表的是sea urchin的密度,淺色陰影部分代表的是kelp的密度,除此之外每組數(shù)據(jù)下面都提示了這些數(shù)據(jù)是根據(jù)sea otters的數(shù)量發(fā)生的改變。再回到答案中直接分析:

  A 根據(jù)two years or less of sea otters 定位到中間的這組數(shù)據(jù),A說sea urchins完全被消除,很明顯看深色陰影部分還是有一點(diǎn)點(diǎn)數(shù)據(jù)的,并沒有為零,所以A錯(cuò)誤。

  B 根據(jù)two years or less of sea otters 定位到中間的這組數(shù)據(jù),B說可以減少sea urchin的威脅,對(duì)比這邊這組數(shù)據(jù)的sea urchins的密度,確實(shí)是減少了,B正確。

  C sea urchins密度增長的同事kelp的密度也按比例增長,很明顯深色陰影部分和淺色陰影部分是一增一減,不可能同時(shí)增長,C錯(cuò)誤。

  D 根據(jù)sea otters were present for ten years or more定位到右邊的這組數(shù)據(jù),答案寫的是kelp密度比sea urchin密度小,看圖中數(shù)據(jù),明顯kelp已經(jīng)瘋漲了,而sea urchin完全為零,D錯(cuò)誤。
