考点1：考察代词(定冠词结构)的指代内容 (2007年理工A考题/ When we were asleep)
18.When (在...的时候)we dream(做梦), there is less(较少的) movement (运动)of electrical waves(电波)in our brains(大脑， 智力).
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(electrical waves(脑电波)和brains(大脑))作为答案线索， 在文章中查找答案相关句：
(第2段)Scientists(科学家) can detect (察觉;检测)when someone(某人) is having a dream(做梦) by using(使用) an instrument(工具，仪器，乐器) which measures(测量) the electrical waves (电波)in the brain. During(在...期间) dreaming, these waves move(移动, 运动)more quickly(迅速地， 很快地). 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 (哺乳动物) studied,including dogs,monkeys,cats,and elephants,and also some birds and reptiles (爬行动物).This period of sleep is called the“D”state for around 50% of their sleep;the period reduces to around 25% by the age of 10.
答案相关句(划线句)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(在做梦期间， 这些波运动的很快)”， 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。
考点2：考察推断能力 (2007年理工A考题/ When we were asleep)
19.Babies(婴儿) dream less than (比...少)older(年长的) children(孩子)A. Right B. Wrong C. Not mentioned
B. 解析：问题句说“婴儿做的梦比儿童做的梦少”。从句意上看，该题属于细节题。利用问题句中的细节信息(babies, older children)作为答案线索, 在文章中查找答案相关句：
(第2段)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 move more quickly.Breathing(呼吸) and pulse(脉搏) rate(比率，速度) also increase(增加),and there are rapid(迅速的) eye movements(运动) under the lids(眼皮),just as though (好像)the dreamer (做梦的人)were really(真正地) looking at(在看) moving(移动的) objects(物体).These signs (迹象， 标记)of dreaming have been detected(已经被检测到) in all mammals (哺乳动物) studied(被研究的), including dogs,monkeys,cats,and elephants,and also some birds and reptiles (爬行动物). This period of sleep is called the“D”state. Babies experience(经历，经验) the “D”state (状态)for around 50% of their sleep(睡眠);the period(时期，周期) reduces(减少) to around 25% by the age of 10
答案相关句(直接涉及答案线索词)说“婴儿大约一半的睡眠时间都处于“D”状态， 这种状态到10岁的时候就减少到了大约25%”， 现在需要确定“D”状态是否与做梦相关。 答案相关句的前一句说“这个时期的睡眠被称为D状态”， 代词通常都是前指，因此继续关注前文内容。 其前一句提到“这些做梦的迹象在所有的哺乳动物中都已经被检测到”。“这些做梦的迹象”是指前文中提到的“在做梦期间出现的呼吸频率， 脉搏频率加快等做梦迹象”， 结合以上内容判断 “这个时期的睡眠”就是指“做梦的状态”， 即“D”状态。 因此判断答案相关句是说“婴儿大约一半的睡眠时间都处于做梦状态， 这种状态到10岁的时候就减少到了大约25%””， 由此推断出“婴儿比儿童的做梦时间长”，因此问题句提供了错误信息。
考点3: 细节信息的查找和确认(答案为“没提到”的常设考点) (2007年理工B/C考题/ Black Holes(黑洞))
20. The sun (太阳) is the heaviest(最重的) star(恒星) in the universe(在宇宙里).
A. Right B. Wrong C. Not mentioned
C.解析：问题句说“太阳是宇宙中最重的恒星”， 从句意上判断该题内容涉及文章中的细节信息， 属于细节信息题。 利用问题句中的特征词(the sun/太阳)作为答案线索， 在文章中查找答案相关句：
Black Holes
Most scientists agree that black holes exist but are nearly impossible to locate. A black hole in the universe is not a solid object, like a planet, but it is shaped like a sphere (球体).Astronomers(天文学家)think that at the center of a black hole there is a single point in space with infinite(无限的)density(稠密).This single point is called a singularity (奇点).If the singularity theory is correct, it means that when a massive star collapses, all the material in it disappears into the singularity. The center of a black hole would not really be a hole at all, but an infinitely dense point. Anything that crosses the black hole is pulled in by its great gravity.
Although black holes do exist, they are difficult to observe. These are the reasons.
● No light or anything else comes out of black holes. As a result, they are invisible to a telescope.
● In astronomical terms, black holes are truly. For example, a black hole formed by the collapse of a giant star would have an event horizon(视界)only 18 miles across.
● The nearest black holes would be dozens of light years away from Earth. One light year is about 6 trillion(万亿)miles. Even the most powerful telescopes could not pick out an object so small at such a great distance.
In 1994 the Hubble Space Telescope provided evidence that black holes exist. There are still answers to be found, however,so black holes remain one of the mysteries of the universe.
结果发现文章中根本没有提到太阳， 也没有提到“the heaviest/最重的”， 因此判断问题句的内容在文章中没有提到。
提示：
如果问题句中的全部或部分信息在文章没有呼应内容，则应该判断该问题句的信息在文章中没有提及。
