GRE阅读题目解析:高效灯泡

2017-01-16 09:30:00来源:网络

  1

  High Towers, a company that occupies several office buildings, is considering installing new energy-efficient lightbulbs in its buildings.

  HT是一家占用多座大楼办公的公司,他们正考虑全部更换高效灯泡。

  2

  The new bulbs require less than half the electricity consumed by the conventional bulbs currently used to produce the same amount of light.

  要达到相同的照明效果,新灯泡只需消耗少于老灯泡一半的电。

  3

  The new bulbs also last considerably longer.

  新灯泡的寿命也长的多。

  4

  It follows that by replacing old bulbs as they bum out with the new kind of bulb, High Towers would significantly reduce its overall lighting costs.

  所以,用新灯泡换掉报废的旧灯泡,HT 会大大节省总体照明费用。

  1. Which of the following, if true, most strengthens the argument given?

  (A) If the new bulbs are widely adopted, as seems likely, they will be produced in large enough quantities to be offered at prices comparable to those of conventional bulbs.

  (B) The utility that supplies High Towers with electricity offers discount rates to its largest customers.

  (C) High Towers has recently signed a contract to occupy an additional small office building.

  (D) High Towers has begun a campaign to encourage its employees to turn off lights whenever they leave a room.

  (E) The company that manufactures the new bulbs has been granted a patent on the innovative technology used in the bulbs and thus has exclusive rights to manufacture them.

  选 A

  A 正确。新灯泡被广泛使用,产量足够大时价格会跟传统灯泡相当。文章告诉我们,新灯泡相对于旧灯泡全是优点,唯独没说价格。而 A 补充了这个因素,说只要大量投产,就能达到跟旧灯泡相当的价格。显然这是个加强结论的选项。

  B 错误项。因为 HT 是用电大户,电力公司会给折扣。两方面考虑,首先,新灯泡的一个优势是耗电量低,省钱,如果现在单位电量的价格下降(打折),那么新灯泡的这个优势相应就被削弱了一些;另外,如果采用了新灯泡,HT 的照明耗电就下降了至少一半,那么电力公司也许就不开出如初的优惠条件了。可见,B 对于换新灯泡的结论,发挥的全是负面作用。

  C 无关项。HT 最近签合同要多租一座小的新楼办公。

  D 无关项。HT 已经发起了一场节能运动,号召员工离开房间就关灯。好的使用习惯,不管用什么灯泡,都省钱。

  E 无关项。灯泡厂申请专利成功了,可以独家生产新灯泡。
