Maybe you have heard about the way bees dance around to send messages to each other and the way dogs bark in different ways to give warnings, to be friendly or to be playful. But did you know about infrasonic communication used by elephants? This is how it works:Humans hear low sounds like thunder rumbling in the sky. But we dont hear sounds lower than this. However, animals such as elephants and hippos can hear much lower sounds than humans can. And whats more, they can make those low sounds as well, and they use them to communicate with each other. This is known as infrasound. The amazing thing about infrasound is that it travels over several kilometers. Higher-level sounds like the one people can hear, dont travel well through walls, leaves, trees and so on, which is why we cant hear sounds from more than 100 meters away. But infrasound is much stronger and things like grass and trees have no influence on it. Therefore, it can travel much further. Elephants can hear infrasonic calls from four kilometers away!There have been reports of people watching groups of elephants feeding or resting and then the elephants suddenly all stopped what they were doing for no reason at all. They obviously heard a warning call from a long way away, but the people didnt hear a sound. In places like a zoo or wildlife park where you can get nearer to animals, it is a bit easier to sense when infrasonic sounds are made. When you stand near mother elephants with their babies in a zoo, you may notice a slight rumbling in the air every few minutesnot loud or strong, but clearly noticed. This is infrasonic communicationthe mother elephants “talking” to their babies.16 . Why does the writer mention bees and dogs in Paragraph1?ABecause they use infrasonic communication.BBecause they communicate like the elephants.CBecause they are examples of animal communication.DBecause people want to learn how they communicate.17 . Which of the following is TRUE about infrasound?AHumans can hear infrasound easily.BIt travels nearly several kilometers.CIt sounds low but cant travel very far.DIt travels well through walls, leaves and so on.18 . In places like zoos, _.Aelephants dont need to make infrasonic soundsBit is easier for elephants to make infrasonic soundsCmother elephants dont let people stand near their babiesDhumans can easily sense infrasonic sounds when they are made19 . Which would be the best title for the passage?ATalking to humansBTalking to animalsCPlaying with humansDPlaying with elephantsTheres much to see under the sea, but you need to remember that light behaves differently in water than in air. The objects appear closer to you than they exactly are. You might find yourself reaching out to touch something and completely missing it.Objects under water will appear larger than they would on the surface, too. Be careful not to tell any stories about the big fish that got away. The fish might not be so big after all! Its just because sometimes things can seem to be as much as about 33 percent bigger in water!Whats more, in deeper water, colors just dont seem as bright. In fact, it looks as if some colors are missing. Remember the color of an object results from the wavelengths(波长) of light that are reflected from its surface. And light is taken in as it moves down through the water.Swimmers wear wet suits to keep warm underwater. Lets take a bright red, yellow, and blue wet suit as an example. These colors are hard to miss on the surface of water. Watch carefully the changes in color as you descend in water. The red part now looks almost black because the red light wavelengths, the longest among these three colors, are missing. As you go down deeper, the same thing will happen to the yellow part and in the end to the blue part. Even at a place of about 6 to 9 meters underwater, you will look terrible, like a ghost(鬼怪)! And you have to wait for your return to the surface to enjoy the bright colors again. Do you have a better understanding of the behavior of the light underwater? We need to be careful about the objects around us and explore(探索) their mysteries by ourselves.20 . You miss the object underwater when you want to touch it because_.Ayour eyesight is quite poorByour are not quick enoughCit is not as close as it seemsDit disappears very quickly21 . The example of the wet suit is used to explain the change of _of an object underwater in paragraph 4.Athe sizeBthe colorCthe positionDthe weight22 . The underlined word “descend” probably means _ in paragraph 4?Amove upBmove on waterCstop breathing for a whileDgo down23 . Which of the following is true according to the passage?AA four-meter-long fish looks three meters long underwater.BMuch water will be taken in by the swimmer deep in the water.CThe wavelengths of red light are longer than those of the blue light.DYou will see a ghost if you go as deep as 6 to 9 meters into the sea.24 . Which of the following would be the best title of the passage?AThe Standard of Color UnderwaterBThe Direction of Light UnderwaterCThe Beauty of Color UnderwaterDThe Behavior of Light UnderwaterThe United States has many different kinds of climate(气候)On the west coast(海岸),the temperature changes very little between summer and winter,but the north central states(中部各州)have a very different kind of climateIn these states,people wear light clothes during the summer,and they need heavy wool or fur clothes in winterIn the southwest,the climate is quite warm during the winter,but hot in summerIn the eastern part of the United States,summer temperatures are very different from winter temperaturesSummers are usually hot,and winters are usually coldSpring temperatures are comfortably warm,and autumn temperatures are quite coolYears ago,people in the cold areas(地区)of the United States did not often get vegetables and fresh fruits during the winterToday trucks and trains carry fruits and vegetables very quickly to all parts of the United StatesIn this way,Americans“send their climate”to people in other states25 .
