8．Below is a selection from a popular science book．
| If blood is red，why are veins （静脉） blue？ Actually，veins are not blue at all．They are more of a clear，yellowish colour．Although blood looks red when it's outside the body，when it's sitting in a vein near the surface of the skin，it's more of a dark reddish purple colour．At the right depth，these blood-filled veins reflect less red light than the surrounding skin，making them look blue by comparison． Which works harder，your heart or your brain？ That kind of question depends on whether you are busy thinking or busy exercising．Your heart works up to three times harder during exercise，and shifts enough blood over a lifetime to fill a supertanker．But，in the long run，your brain probably tips it，because even when you're sitting still your brain is using twice as much energy as your heart，and it takes four to five tunes as much blood to feed it． Why do teeth fall out，and why don't they grow back in grown-ups？ Baby （or"milk"） teeth do not last long； they fall out to make room for bigger，stronger adult teeth later on．Adult teeth fall out when they become damaged，decayed and infected by bacteria．Once this second set of teeth has grown in，you're done．When they're gone，they're gone．This is because nature figures you're set for life，and what controls regrowth of your teeth switches off． Do old people shrink as they age？ Yes and do．Many people do get shorter as they age．But，when they do，it isn't because they're shrinking all over．They simply lose height as their spine（脊柱） becomes shorter and more curved due to disuse and the effects，of gravity （重力）．Many （but not all） men and women do lose height as they get older．Men lose an average of 3-4cm in height as they age，while women may lose 5cm or more．If you live to be 200years old，would you keep shrinking till you were，like 60cm tall，like a little boy again？No，because old people don't really shrink!It is not that they are growing backwards----their legs，arms and backbones getting shorter．When they do get shorter，it's because the spine has shortened a little．Or，more often，become more bait and curved． Why does spinning make you dizzy （眩晕的）？ Because your brain gets confused between what you're seeing and what you're feeling．The brain senses that you're spinning using special gravity-and-motion-sensing organs in your inner ear，which work together with your eyes to keep your vision and balance stable．But when you suddenly stop spinning the system goes out of control，and your brain thinks you're moving while you're Dot! Where do feelings and emotions come from？ Mostly from an ancient part of the brain called the limbic system．All mammals have this brain area-from mice to dogs，cats，and humans．So all mammals feel basic emotions like fear，pain and pleasure．But since human feelings also involve other，newer bits of the brain，we feel more complex emotions than any other animal on the planet． If exercise wears you out，how can it be good for you？ Because our bodies adapt to everything we do to them．And as far as your body is concerned，it's"use it，or lost it"!It's not that exercise makes you healthy； it's more that a lack of exercise leaves your body weak and easily affected by disease． |

分析 本文是一篇广告布告类阅读，文章从科学的角度解释了几个人们普遍感到困惑的问题．比如，为什么血液是红色的而血管却呈现出深蓝色呢？为什么牙齿会掉而且成年后不再长出新的牙齿呢？为什么人老了身高就变矮了呢？读了这篇文章以后，你就会恍然大悟．
解答 67-70 BCAD
67．B．细节理解题．根据第一段第二句"Although blood looks red when it's outside the body，when it's sitting in the vein near the surface of the skin，it's more of a dark reddish purple color．"可知在靠近皮肤表层的血管里，血液是紫红色．故选B．
68．C．细节理解题．根据第八段的"when they do get shorter，it's not because the spine has shortened a little．Or more often，become more bent and curved．"可知老年人变矮不是因为他们的脊柱变短，更多的原因是因为他们的脊柱变弯曲．A选项不符合文中的内容They simply lose height as their spine（脊柱）becomes shorter and more curved due to disuse and the effects of gravity（重力）；B选项的内容文中没有提及；D选项的内容与文中的描述相反．故选C．
67．A．细节理解题．根据第二段最后一句"But in the long run，your brain probably tips it，because even when you're sitting still your brain is using twice as much energy as your heart，and it takes four to five times as much blood to feed it．"可知我们可以推断从长远看来，大脑要比心脏工作更多．通过第五段最后一句"But when you suddenly stop spinning the system goes out of control，and your brain thinks you'removing while you're not"可知当我们突然停止旋转时才会感到眩晕，所以B项错误；通过第六段最后一句"But since human feelings also involve other，newer bits of the brain，we feel more complex emotions than any other animal on this planet．"可知C，D两项错误．故选A．
68．D．推理判断题．本篇的写作意图就是让我们了解我们的身体，为我们提供一些基本的信息，故选B．
点评 阅读这类文章时，也应该在整体把握文章结构的前提下，主要注意细节信息．细节题题干都是相应原文的变形（如同义改写、词性转换等），因此要找到答案一定要找到题干在原文中的出处，再把原文和选项相比较．做题时，根据所提问题用寻读、跳读的方法可达到事半功倍的效果．
根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Doctors say anger can be an extremely damaging emotion, unless you learn how to deal with it. They warn that anger can lead to heart disease, stomach problems, headaches, emotional problems and possibly cancer.
1.________ Some people express anger openly in a calm reasonable way. Others burst with anger, and scream and yell. But other people keep their anger inside. They can not or will not express it. This is called repressing anger.
For years many doctors thought that repressing anger was more dangerous to a person’s health than expressing it. They said that when a person is angry, the brain releases the same hormones (荷尔蒙). They speed the heart rate, raise blood pressure, or sugar into the blood, etc. 2.________
Some doctors say that both repressing and expressing anger can be dangerous. They believe that those who express anger violently may be more likely to develop heart disease, and they believe that those who keep anger inside may face a greater danger of high blood pressure.
3.________ They say the first step is to admit that you are angry and to recognize the real cause of the anger, then decide if the cause is serious enough to get angry about. If it is, they say, “4.________ Wait until your anger has cooled down and you are able to express yourself calmly and reasonably.”
Doctors say that a good way to deal with anger is to find humor in the situation that has made you angry. 5.________
A. In general the person feels excited and ready to act.
B. They said that laughter is much healthier than anger.
C. Expressing anger violently is more harmful than repressing it.
D. Anger may cause you a cancer.
E. Do not express your anger while angry.
F. Anger is a normal emotion that we all feel from time to time.
G. Doctors say the solution is learning how to deal with anger.
