However, spending too much time in space may cause health problems, according to NASA.That's why astronauts shouldn't spend more than six months on the International Space Station(ISS) at a time. Muscle and boneless In a weightless environment, astronauts don't need to use their muscles to support themselves. Therefore, their muscles start shrinking(萎缩). To keep their muscles strong, astronauts need to exercise about 2 hours each day on the ISS. The weightless environment also causes astronauts' bones to lose minerals(矿物质), with density(密度) dropping at over 1 percent per month. The rate of bone loss for elderly people on the Earth is 1 to 1.5 percent per year. Sleep disorder In space, the sun rises every 90 minutes. It is hard for astronauts to get used to this light-dark cycle when they sleep. Also, they need to sleep in a sleeping bag that is fixed to a wall, which is uncomfortable. Astronauts now have individual sleeping pods(分离仓) that help shut out some of the light. Still, studies have found that most astronauts only sleep about six hours each night, even though they should have eight and a half hours. Brain changes Scientists have found that the position of the brain changes during spaceflight. It shifts upward within the skull(头骨). This can affect how the brain deals with how we see, stay balanced and move around. That's why some astronauts can't control their movement and balance after returning to the earth. 3 Scientists have also found that astronauts may get used to this change after going on more spaceflights. But they still need to do more research. 1.According to the passage, astronauts may suffer the following health problems: . ( ) a.bone loss b. sleep disorder c. mental disease d. muscle shrinking e. high blood pressure A.abe B.abc C.abd D.bcd 2.According to the passage, which one is NOT TRUE? ( ) A.Astronauts don't suffer muscle problems after returning to the earth. B.Astronauts sleep in individual sleeping pods to stay warm at night. C.In space, astronauts have the problem that their muscles start shrinking. D.Most astronauts only sleep less than eight and a half hours. 3.How can astronauts deal with the problem of losing their balance? ( ) A.They can walk upside-down on the earth. B.They can go on more spaceflights. C.They can take some medicine. D.They can sleep more and rest. 4.What's the best title for this passage? ( ) A.Dream of traveling into space B.Health problems in space C.Muscle and bone loss in space D.Astronauts in space Passage 2 [2019·连云港改编] The human body is a machine that can raise lots of interesting questions. Why, for example, are yawns(呵欠)contagious(传染的)?What's up with ice-cream 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 aren't exactly sure what causes the brain freeze when we eat ice-cream or other super-cold foods too quickly, though some believe it'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 ice-cream headache by rapidly rubbing your tongue across 4 the roof of your mouth to help warm up things. What causes my stomach to make a low continuous noise when I'm hungry? Actually, your stomach makes noise whether you're hungry or full; you just hear it more clearly when you'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.And that's what you're hearing when your stomach makes noise. Why do I blush when I'm embarrassed? When you're embarrassed,your brain releases a shot of adrenaline(肾上腺素), which makes your heart race and blood vessels become larger in size.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? It's a common thing but researchers don't have a good explanation for it.They do, however, know this happens only with humans and chimpanzees(黑猩猩). 5.What is the meaning of the underlined word “tighten”? ( ) A.To become looser. B.To become smaller. C.To become longer. D.To become shorter. 6.What's the structure of the passage? ( ) A. B. C. D. 7.Which of the following statements is TRUE?( ) A.There is no way for you to improve an ice-cream headache. B.Researchers have found out the actual function of blushing. C.Your stomach makes noise only when you are hungry. D.Researchers don't have a good explanation for why yawns are contagious. 8.What is the best title of the passage? ( ) A.Some Interesting Facts B.Our Strange Body 5 C.Some Useful Discoveries D.Our Amazing Feelings 【参考答案】 Ⅰ.1—5 ACDDB 6—10 DCACB 11—15 ADCAB Ⅱ.Passage 1 [主旨大意]本文是一篇说明文,讲述了去太空中会遇到的健康问题。 1.C 细节理解题。根据副标题可知选 C。 2.B 推理判断题。根据文章“Astronauts now have individual sleeping pods(分离仓) that help shut out some of the light.”可知选 B。 3.B 细节理解题。根据文章“Scientists have also found that astronauts may get used to this change after going on more spaceflights.”可知选 B。 4.B 主旨大意题。根据开头“Many people dream of traveling into outer space. However, spending too much time in space may cause health problems, according to NASA.”和副标题可知选 B,太空健康问题。 Passage 2 [文章大意]本文主要讲述我们身体的一些有趣的问题,包括吃冰激凌太快会头痛、尴尬时会脸红、 哈欠会传染等。 5.B 词义猜测题。根据 Blood vessels in the head tighten to stop the loss of body heat and then relax to let blood flow rise.可知,头部的血管变紧,以阻止身体热量的流失,然后放松,让血液流动起来。tighten 的意思与 relax 相反, to become smaller 最贴切。故选 B。 6.C 段落结构题。通读全文可知,第一段是总起段,剩下的四段是并列段落。故选 C。 7.D 细节理解题。根据 Have you ever yawned in front of someone, only to have them yawn right back? It's a common thing but researchers don't have a good explanation for it.你是否曾经在别人面前打 哈欠,结果却让他们马上打哈欠?这是一件很常见的事情,但研究人员对此没有很好的解释。可知,关于打哈欠 为什么会传染,研究者也没有好的解释,故选 D。 8.B 主旨大意题。通读全文可知,本文主要讲述我们身体的一些有趣的问题,包括吃冰激凌太快会头痛、尴尬 时会脸红、哈欠会传染等,所以 Our Strange Body(我们奇怪的身体)是最佳标题,故选 B。
