考点1：考察代词的指代内容 18.When we dream, there is less movement of electrical wavesin our brains. A. Right B. Wrong C. Not mentioned B. 解析：问题句说在我们做梦的时候， 我们大脑中的脑电波运动较少 从句意上看，该题属于细节题。利用问题句中的细节信息词和brains)作为答案线索， 在文章中查找答案相关句： Scientists can detect when someone is having a dream by using an instrument which measures the electrical waves in the brain. During dreaming, these waves movemore quickly. Breathing and pulse rate also increase,and there are rapid eye movements under the lids,just as though the dreamer were really looking at moving objects.These signs of dreaming have been detected in all mammals studied,including dogs,monkeys,cats,and elephants,and also some birds and reptiles .This period of sleep is called theDstate for around 50% of their sleep;the period reduces to around 25% by the age of 10. 答案相关句说科学家们可以借助一种检测大脑中脑电波的设备检测出人是否在做梦。该句没有谈到做梦与脑电波之间的关系， 于是接着关注接下来的句子。接下来的句子说During dreaming,these waves move more quickly， 根据代词前指的特性判断these waves就是指答案相关句中提到的脑电波， 综合这两句话的内容得出的结论是做梦时脑电波运动较快， 显然问题句提供了错误信息。 |
