The elephant’s call will be familiar to most people, but the animals also give out growls (低吼). Their growls, however, are only partly audible (听得见的); two-thirds of the call is at frequencies that are too low to be picked up by our hearing. To learn more about the inaudible part of the growl, the team attached (附在……上面) a microphone sensitive to these low frequencies and a GPS tracking system to eight of the zoo’s female elephants. The researchers could then relate the noises the animals were making to what they were doing. Matt Anderson, who led the project, told BBC News, “We’re excited to learn how they interact and contact with one another.”
The team has already learned that pregnant females use this low frequency communication to announce to the rest of their long gestation (妊娠期) of over two years, in the last 12 days we see the low part of the growl, which we can’t hear. This we believe is to announce to the rest of the herd that the baby is upcoming,” said Dr Anderson.
The researchers believe that this also warns the elephants to look out for coming danger. “You may think that a baby calf of about 300 pounds would not be as open to predation (捕食) as other species,” he says. “But packs of hyenas (袋狼) are a big threat in the wild.”
Female elephants are only in season for around four days every four years and these calls can be heard by males more than two miles away.
小题1:Why some elephants’ call is called “secret language”?
A.Because it can’t be heard by human ears. |
B.Because it can only be heard by female elephants. |
C.Because people don’t know its meanings. |
D.Because people haven’t studied it completely. |
A.where the elephants usually go |
B.what the elephants’ growls really mean |
C.how mother elephants raise baby calves |
D.how elephants protect their babies. |
A.show the location where she is staying |
B.ask for help when she losses her way |

解析
试题分析:本文主要讲述的是对定位(大象)之间的语言的研究。
小题1:A 细节题。根据文章5,6行Their growls, however, are only partly audible (听得见的); two-thirds of the call is at frequencies that are too low to be picked up by our hearing.说明很多声音我们人类都无法听见,故称之为秘密语言,故A正确。
小题2:B 推理题。感觉第二段4,5行To learn more about the inaudible part of the growl, the team attached (附在……上面) a microphone sensitive to these low frequencies and a GPS tracking system to eight of the zoo’s female elephants.说明这样做是为了了解更多的关于我们听不见的语言,故B正确。
小题3:D 细节题。根据文章第三段3,4行in the last 12 days we see the low part of the growl, which we can’t hear. This we believe is to announce to the rest of the herd that the baby is upcoming,”说明大象用这样的声音通知同伴她要产仔了。故D正确。
小题4:C 主旨大意题。本文主要讲述的是对定位(大象)之间的语言的研究,文章举了具体的例子来说明。故C项正确。
点评:本文与一般的科普类短文不一样,是关于动物的语言的话题,词汇的难度较小,要养成在上下文串联中猜测词义的能力,根据上下文中出现的同义词,近义词,反义词,以及词义的解释来理解生词。同时要抓住文章的中心,不要受其他信息的影响。要根据题目及选项以及文章的上下文串联合理的判断推理。

举一反三
However, they sing most of the time for a very different reason. ____2___ Some scientists believe that birds do sing some of the time just because they are happy.
Do you know what a “territory” is? A territory is an area that an animal, usually the male, claims(声称)as its own. ____3___ No other families of the same species are welcome. Your yard and house are your territory where only your family and friends are welcome. If a stranger should enter your territory and threaten you, you might shout. Probably this would be enough to frighten him away. If so, you have actually scared the stranger away without having to fight him. A bird does the same thing. But he expects an outsider almost any time, especially at nesting(筑巢)season. So he is screaming all the time, whether he can see an outsider or not.__4__.
Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs. You can see that birds have a language all their own. ___5__
A.Only he and his family are welcome there. |
B.Most of it has to do with attracting mates and setting up territories. |
C.Have you ever wondered why birds sing? |
D.Their singing is actually a warning to other birds to stay out of their territory. |
F. Most of the language is widely used.
G. This screaming is what we call a bird’s song, and it is usually enough to keep an outsider away.

Perhaps the greatest turning point in my life came when I was in high school and I wrote a letter to the famous Scripps Oceanographic Institution, asking how I might learn more about the sea.A kind scientist answered my letter and told me how to apply to Scripps for a summer scholarship, which I received.During one of their courses that summer, I met Dr.Robert Norris, a marine geologist.He loved the sea almost as much as I did.Soon he suggested I consider his school, the University of California, for my study.One year later I became a member of the freshman class.
Now my love affair with the sea became a serious endeavor(艰苦的努力).If I wanted to be an undersea explorer, I needed to learn as much as I could about the laws of the physical world that controlled the environment I wanted to enter.The undersea world is not our natural world.It is unforgiving to those who make mistakes.At its greatest depths the water temperature is near freezing, the pressure is eight tons per square inch, and it is totally dark.It is easy to get lost in such a world.I needed to learn a lot about geography, navigation, geology, biology, and many other things.
I decided another important thing for me to do was to join the U.S.Navy.If I was going to be an undersea explorer, I would have to lead men and women on dangerous adventures where they might get hurt, and I didn"t want that to happen.
In the Navy I learned discipline, organization, and how to motivate and lead people on adventures so that we could explore the wonders of the deep.
Finally, the time came to put all that I had learned to use, to go forth with a team of men and women and explore an adventure I am still on and hope to be on for many years to come.

C.thought they were needed to fully understand the ocean |
D.believed it would help him succeed in the Navy |
A.develop his leadership skills |
B.get along with people under stress |
C.learn about the dangers of the ocean |
D.gather specific information about ocean life |

An X-ray of a painting is one of the best ways to tell if it was created by a famous painter or if it is a forgery(赝品).If there is a question as to whether an old master has painted a certain painting or not, X-rays are made and compared to those of paintings that are known to be original.If the brushstrokes (笔迹) , for example, are shown to be totally different than in other work done by a certain artist, then the painting is proved to be a fake copy.
Since modern paints are usually made from different materials than paints of hundreds of years ago, the image they leave on an X-ray film looks different.This is another way X-rays can be used to spot a forgery.A modem artist will try to make a forgery look hundreds of years old by painting dirty varnish on it or by using artificial means to get the varnish to look cracked.To the naked eye the forgery may look old, but when a careful study of the X-ray image is made, the deception is obvious.
It was common many years ago for an artist to finish a painting, decide it wasn"t any good, and paint a completely different picture on top of it.Or artists would paint over others" work —it was their version of recycling.Taking an X-ray is the only way to find out if there is a picture underneath the picture you see with your eyes.Sometimes museums will be more interested in the painting beneath than the one on top, and will restore the older one by having the top layer painstakingly removed.
小题1:What is the main purpose of the article?
A.To provide information to police who are looking for stolen art. |
B.To persuade art dealers to check for fake copies before selling art. |
C.To explain how modern technology can be applied in unique ways. |
D.To help artists restore damaged artwork to its original appearance. |
A.make repairs on paintings in the past |
B.identify the authenticity of an artwork |
C.change the materials of a forgery |
D.remove the recyclable paints |
A.comparison | B.drawback | C.trickery | D.judgement |
A.X-ray Detectives |

Should Good Sportsmanship Be Taught in School?
Almost everyone feels that it is important for young people to win fairly and show respect toward others.Should good sportsmanship, then, be taught in school? Critics do not think so. 1 Presented here are the most important benefits of teaching sportsmanship.
Teaching good sportsmanship and having a positive attitude in activities like sports, class elections, and science fair competitions are critical to success in school. 2 Acting calmly under pressure helps young adults succeed not only in sports but also in life.
3 A person cannot play by the rules if he or she does not understand what the rules are.Knowing the rules also applies to other activities.If students enter a science fair competition, for example, they must follow the guidelines. Those who know the rules are much more likely to succeed.When students learn sportsmanship, they discover, how knowing the rules relates to achievement.
Good players become skilled at handling responsibility.When people accept responsibility, they achieve their best.Positive thinkers, moreover, influence others, especially those who are struggling with a problem.A gifted basketball player, for example, might teach skills to a less-talented player.Helping others raises the performance of the entire team.The team, consequently, could reach new heights and set new records. 4 Those who do not practice sportsmanship pass off responsibility.For them, if an opportunity is lost, it is someone else" s fault.When students participate on a team, they benefit by learning to accept responsibility, encourage others and own up to(认错) mistakes.
Sportsmanship is a winning idea.It must be taught in school.Students need direction to become good sports".Students will be responsible for their own actions and will have a positive influence on others.As students enter the workforce, businesses benefit.The community also benefits because these students will someday become leaders. 5
A.We need to educate students about how sportsmanship pays off for everyone. |
B.However, the stronger argument favors teaching good sportsmanship. |
C.Sports help young adults learn how to team up with others. |
D.Good sportsmanship also means admitting mistakes. |
F.It is natural that players should be eager to win.
G.Good team players know the rules of the game.
