托福阅读你肯定不知道的做题套路

2016-03-29 14:45:29来源:新东方在线整理

  During wakefulness, breathing is controlled by two interacting systems.The first is an automatic, metabolic system whose control is centered in thebrain stem. It subconsciously adjusts breathing rate and depth in order toregulate the levels of carbon dioxide (CO2) and oxygen (O2), and the acid-baseratio in the blood. The second system is the voluntary, behavioral system. Itscontrol center is based in the forebrain, and it regulates breathing for use inspeech, singing, sighing, and so on. It is capable of ignoring or overridingthe automatic, metabolic system and produces an irregular pattern of breathing.

  2.According to paragraph 2, all of the following are true of thevoluntary breathing system EXCEPT:

  ○It has its control center in thebrain stem.

  ○It controls breathing for a numberof activities during wakefulness.

  ○It is able to bypass the automatic system.

  ○It produces an irregular breathing pattern.

  ✔解析:

  • 题干关键词:the voluntary breathing system

  • 文中定位点:The second system is the voluntary,behavioral system.

  • 反义推理:看到second则一定有first,思考是first的内容对应选项则一定不符合second的内容所以文中The first is an automatic, metabolic systemwhose control is centered in the brain stem.

  ☞因此正确答案为A

  看上去都是套路啊,不知道你们都学会了吗?
