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(duì)抗反應(yīng)）. 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?

Last month, China started its official online mapping service, Map World. Through this free online service users can fly over mountains and valleys around the world and search for restaurants and traffic information across the country for free, said Xu Deming, director of the State Bureau of Surveying and Mapping （SBSM）. The bureau, which does China39。s surveying and mapping work, is in charge of the Map World project. Users can get into Map World through or and search for 2 and 3D images from across the world. The home page shows a view of the Great Wall. It took about two years to prepare the service with all the satellite（衛(wèi)星） images taken from 2006 to 2010, said Jiang Jie, director of the database department（數(shù)據(jù)庫(kù)部門） under SBSM. The technology（技術(shù)） and website are still at an early stage. The images from inside China are detailed. Users can see close pictures of roadsides. But the views of places outside China are less clear. Service providers have more than 80 machines, with the ability to deal with 10 million requests （請(qǐng)求） daily, while Google Earth, Google39。s mapping service, has thousands of machines, Jiang said. Our map service can update（更新） data about twice a year, but Google Earth can update its information every couple of minutes, through satellites, J
