攻破新GRE逻辑阅读NO.25

所属专题:GRE阅读  来源:互联网    要点:GRE考试  
编辑点评: 新版GRE考试的考生都觉得语文部分的题难了,这主要是由于新GRE逻辑阅读部分的内容考生还是有点不习惯,或是没有准备充足。本文为大家整理一些新GRE逻辑阅读的练习题,希望考生能从平日的练习中总结规律,找到解题技巧。

In household electric ovens, the heating element has only two settings—on and off. A thermostat connected to the oven's temperature knob is the only control on temperature, automatically switching the element off when the indicated temperature is reached, which happens quickly in modern ovens, and subsequently on or off as needed to maintain temperature.

Which of the following statements is most strongly supported by the information above?

(A) Because in each case the heating element alternates between on and off, a modern household electric oven uses little more power at its maximum temperature setting than it does at its lowest temperature setting.

(B) Once the indicated temperature has been reached and is being maintained by the thermostat, the heating element will be switched off for a greater proportion of the time than it is switched on.

(C) The accuracy with which household electric ovens maintain their temperature could not be improved on by ovens whose heating elements have more than two settings.

(D) In a correctly functioning modern household electric oven, tile thermostat will generally not switch the heating element off when the oven's temperature is more than a few degrees above the indicated temperature.

(E) If the thermostat of a modern household electric oven is disabled so that the heating element remains switched on, the oven's temperature can eventually become higher than the maximum temperature setting on its temperature knob.

答案:(E)

问题:下面那一个陈述最被上面的信息所支持?

读题:家用电子烤箱的供热系统仅有两种状态开和关,与烤箱温度柄相连的恒温器是对温度的仅有控制,当达到设定的温度时就会自动关上。之后根据保持温度的需要自动打开关闭。

A. 由于家用电子烤箱的供热系统总在开、关两种状态转换,因此最高温度状态比最低温度状态多用不了多少电。(没有涉及用电量的比较)

B. 一旦达到设定的温度并由怛温器保证该温度的话,供热系统关闭的时间要比打开的时间长。(上文没有涉及这两方面时间的比较)

C. 即使供热系统具有两种以上状态的烤箱也无法提高家用电子烤箱保持温度的精确度。

D. 在运转正常的现代家用电子烤箱中,如果烤箱的温度要比设定的温度还要高好几度,恒温器一般不会关闭供热系统。

E. 如果现代家用电子烤箱的恒温器坏了,而供热系统一直开着,那么最后烤箱的温度就可能超过温度柄所设定的最高温度。(原来是到设定温度就关闭,现在坏了,供热系统继续开,当然最后温度就有可能超过)

对于新GRE逻辑阅读,考生除了采取题海战术,其实更应该做的就是总结。如果能从平日的练习中找到解新GRE逻辑阅读题的思路,那么,要比采取题海战术更好。
