Why, for example, are yawns （呵欠） contagious （傳染的）? What39。s up with icecream headaches? Here are answers to these and other questions about our bodies. Why do I get a headache when I eat ice cream too quickly? Scientists aren39。t exactly sure what causes the brain freeze when we eat ice cream or other super cold foods too quickly, though some believe it39。s the result of changed blood .flow in the nervous system. Blood vessels in the head tighten to stop the loss of body heat and then relax to let blood flow rise。 that sudden rush of blood is what causes the headache. You can improve an icecream headache by rapidly rubbing your tongue across the roof of your mouth to help warm up things. What causes my stomach to make a low continuous noise when I39。m hungry? Actually, your stomach makes noise whether you39。re hungry or full。 you just hear it more clearly when you39。re hungry. Think of your digestive tract（消化道）as a really long tube lined with smooth muscle tissue. These muscles move food, fluids and gas through your digestive tract. ___________. It can make you feel embarrassed（尷尬的）but is nothing to worry about. Why do I blush when I39。m embarrassed? When you39。re embarrassed, your brain releases a shot of adrenaline（腎上腺素）, which makes your heart race and blood vessels bee larger in size. All this happens to increase blood flow and oxygen delivery throughout the body in a fightorflight reaction（對抗反應）. There are a lot of tiny blood vessels in your face, which turn noticeably redder from this sudden rush of blood. As for the actual function of blushing, researchers are still trying to find that one out. Why are yawns contagious? Have you ever yawned in front of someone, only to have them yawn right back? It39。s a mon thing, but researchers don39。t have a good explanation for it. They do, however, know this happens only with humans and chimpanzees（黑猩猩）. A bigger question puzzling scientists is why we yawn at all. It used to be thought that yawning showed that oxygen to the brain was not enough, but that39。s just a myth. A growing body of research now shows that yawning is nature39。s way of keeping our brains cool.（1）What is the meaning of the underlined word tighten?

Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest problems is pollution. To pollute means to make things dirty. Pollution es in many ways. We see it, smell it, drink it and even heart it. Man has been polluting the earth. The more people have, the more pollution bees. Many years ago, the problem was nor so serious because there were not so many people. When the land was used up or the river was dirty in one place, man moved to another place. But this is no longer true. Man is now slowly polluting the whole world. Air pollution is still the most serious. It39。s bad for all living things in the world, but it is not the only one kind of pollution, Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us angry more easily. Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in the city, and from putting dirty smoke into the air. Pollution by sulfur dioxide （So2） is now the most dangerous kind of air pollution. It is caused by heavy traffic. We are sure that if there are fewer people driving, there will be less air pollution. The earth is our home. We must take care of it. That means keeping the la
