Howling is a behavior commonly observed among a wolf nark. An animals, wolves work together to hunt and rely on howling was an important means of communication each other. There are different explants of a wolf’s howl and it appears that there may be more to discover. One theory is that wolves howl to bend better together. It’s almost as if howling together helps the pack stay together. Perhaps something similar to people feeling a sense of involvement with each other when singing a song together . But this theory may be wrong, explains Fred H. Harington, a professor who studies wolf behavior. Indeed, there have been tines when wolves have been seen one moment howling in a exhorts, and the next, quarreling anions each other. It appears that usually the lowest-tanking menthes of the pack may actually be “punished” for Joining in the churs at times. So is howling a way to strcagthen a social boad or just a way to reconfirm status among its members? ——Why do welves howl for sure? What is cleat, however, is that howling is often used among packmates to locate each other. Hunting grounds are distant and it happens that woloves may separate from one another at times. When this happens, howling appcars to be an ercellent means of gathering. Howling, interestingly, is a contagious behaviour. When one wolf starts to howl, very likely others will follow. This is often seen to occat in the morning, as if wolves were doing some sotr of “roll rall”where wolves all howl togeter to howl, very likely others will follow. This is often seen to occar in the morning, as if wolves were doing w some sotr of “roll call”where wolves all howl together to repotr their pteence. 小题1:.What the por similarity between wolves’ how humaes ting in chorus?A.The act of calling each other. | B.the sense of accomplishment. | C.The act of hunting for something. | D.The sense of belonging to a group. | 小题2:.Why does Harrington think the“secial boad”theory may be wrong?A.Wolves separate from each other after howling. | B.Wolves tend to protect their hunting grounds. | C.Wolves sometimes have quarrels after howling together. | D.Wolves of low rank are encouraged to join in the chorus. | 小题3:Reseatchers are sure that wolves often howl to______.A.show their ranks | B.find their companion | C.report the missing ones | D.express their lonelingess | 小题4:“Howling… is a contagious behaviour”(in the last paragraph)means_ ______.A.howling is a signal for hunting | B.howling is a way of communication | C.howling aften occurs in the morning | D.howling spreads from one to another |

Soon you may be able to throw your wallet away and pay for things with a quick wave of your smart phone over an electroue scannet. In January, Starbucks announced that customers could start using their phones to buy coffee in 6,800 of its states. This is the first pay-by-phone practice in the U.S., but we’re likely to see more witeless payment alternatives as something called ucar field communcation(NFC)GETS IN TO America’s consumet electanies. Last Deccmbet some new smart phanes which cantain an NFC chip were introduced to the public. Already in use in part of Asia and Europe, NFC allows shoppers to wave theie phones a few inchs above a payment terminal-a contact-free system build for speed and convenience. plan a few incees live a payment tetminal a one a few ptaht need to be worked out, like who will get to collect the profitable trunsacian(交易)fees. Although some credit card providers have been experimenting with wave and pay systems that use NFC enabled credit cards, cellphone service providers truay try to mused their way into the point of sale (POS)market. Three big cell phone service providers have formed a joinf tenture(合资企业)that will go into opention over the next 15 months. Its goal is“to lead the U.S. payments industry from cards to mobile phone.” The other big NFC sue, apart from how paymeats will be processed, is security, For instance, what’s to stop a thief from digitally pickpocketing you? “We’re still not at the point where an attacker can just brush against yee in a crowd and steal all the money out of your phone,”says Jimmy Shah.

Every pet owner loves his pet .There is no argument here. But when we asked our readers whether they would clone their beloved animals , the responses were split(分裂) almost down the middle . Of the 228 readers who answered it ,108 would clone, 111 would not and nine weighed each side without offering an opinion . Clearly, from readers’ response, this is an issue that reaches deeply into both the joy and eventual (最终的)sadness of owning a pet. It speaks, as well, to people’s widely differing expectations over the developing scientific procedure (步骤) Most of the readers who favored the idea strongly believed it would produce at least a close copy of the original; many felt the process would actually return an exact copy. Those on the other side, however, held little hope that clone could truly recreate a pet; many simply did not wish to go against the natural law of life and death. Both sides expressed equal love for their animals. More of them owned “the best dog/cat in the world”. They thought of their pets as their “best friend” or “a member of the family”. They told moving stories of pets’ heroism, intelligence and selfless devotion. No wonder the loss is so disturbing---and the cloning so attractive. “People become very close to their animals, and the loss can be just as hard to bear as when a friend or family member dies,” says Gary Kowalski, author of goodbye, Friend: Healing Wisdom for Anyone Who Has Ever Lost a Pet. “For me, cloning feels like an attempt to turn death away…It’s understandable. Death is always painful. It’s difficult to deal with. It’s hard to accept.” But would cloning reduce the blow? This question seems to be at the heart of this problem. 小题1: As far as the cloning of pets is concerned, a recent survey shows that, of all pet owners, .A.a lot more of them are for it | B.a lot more of them are against it | C.very few of them are willing to tell their opinions . | D.about half of them are for it and the other half against it | 小题2: The expression “eventual sadness of owning a pet.” (in paragraph 3) refers to .A.the death of one’s pet | B.the final ownership of a pet | C.the troubles one has to deal with in keeping a pet | D.the dangers involved in the cloning of a pet | 小题3: In spite of their differences on the problem of cloning, it seems that .A.all pet owners love their pets very much | B.all pet owners try to go against the natural law of life and death | C.people who support cloning love their pets more | D.people who dislike cloning love their pets more | 小题4: From what Gary Kowalski says, we can know that he .A.has never thought about the problem of cloning | B.thinks it hard to accept the idea of cloning pets | C.is in favor of the idea of cloning pets | D.is all against the cloning of pets |

Plastics are considered one of the most serious pollutants causing environmental problems. The garbage containing plastics end up in the waterways that eventually flow into the oceans. Accumulation (聚集)of plastic in the ocean endangers marine life and pollutes the water. Does a plastic continent exist? Yes, a plastic continent does exist and was discovered by Captain Charles Moore a decade ago. The plastic continent is twice the size of Britain and it is the region between the Hawaii Islands and California in the central Pacific Ocean. One of the causes of the lack of marine life in this region is due to pollution and pollutants are none other than plastics. Captain Charles Moore believes plastic waste started accumulating in the 1950s. The plastic continent is the man-made continent of floating plastic waste. The fisher men and the sailors have avoided this region for years. The reasons are: 1. There are no fish here because of the lack of nutrients. 2. The zone also lacks the wind that is essential for sailing. To do research on the ocean pollution, Captain Moore founded Algalita Marine Research Foundation. Other organizations such as Greenpeace supported his cause. The reports of The United Nations Environment Program show that millions of seabirds and marine animals are dying due to the invasion(入侵)of plastics. The waste plastics can be recycled, but in fact they are being thrown into the oceans. The marine animals mistake these for food and eat them. This leads to their death that affects the marine food chain. To save the oceans from the plastic continent you need to reduce the use of plastics, reuse plastic bags and recycle plastics. 小题1: What can we learn from the first paragraph? A.A plastic continent does exist in the Pacific Ocean | B.Endangered marine life is well protected. | C.Plastics are one of the main causes of water pollution. | D.Plastics should be forbidden in people’s daily life. | 小题2: What is the direct influence of the plastic continent?A.Local fishermen have to fish in other areas. | B.The water becomes shallow and fish have to move away. | C.The wind is too strong there and it makes sailing more difficult. | D.It makes people realize the importance of protecting the environment. | 小题3: It is implied that the work of plastic recycling proves to be ______.A.effective | B.expensive | C.a difficult task | D.not good enough | 小题4:What can we learn from the passage?A.Many marine animals are dying due to the broken marine food chain. | B.Captain Moore founded Greenpeace to do research on the ocean pollution. | C.The marine animals have no choice but to eat plastics for lack of food. | D.There are three ways to prevent the oceans from becoming a plastic continent. |

Motorists who used to listen to the radio or their favorite tunes on CDs may have a new way to entertain themselves, after engineers in Japan developed a musical road surface. A team from the Hokkaido Industrial Research Institute has built a number of“melody roads,”which use cars as tuning forks to play music as they travel. The concept works by using grooves(凹槽).They are cut at very specific intervals in the road surface. The melody road uses the spaces between to create different notes. Depending on how far apart the grooves are, a car moving over them will produce a series of high or low notes, and designers are able to create a distinct tune. Paten documents for the design describe it as notches “formed in a road surface so as to play a melody without producing simple sound or rhythm and reproduce melody-like tones”. There are three musical strips in central and northern Japan—one of which plays the tune of a Japanese pop song. Reports say the system was invented by Shizuo Shinoda. He scraped some markings into a road with a bulldozer before driving over them and found that they helped to produce all kinds of tones. The optimal speed for melody road is 44kph,but people say it is not always easy to get the intended sound. “You need to keep the car windows closed to hear well,”wrote one Japanese blogger.“Driving too fast will sound like playing fast forward, while driving around 12mph[20km/h]has a slow-motion effect, making you almost car-sick.” 小题1:According to the passage, melody roads use to create different notes.A.cars | B.grooves | C.spaces between intervals | D.bulldozers | 小题2:We can learn from the passage that the highness of notes is depended on .A.how far the grooves are | B.how big the grooves are | C.the number of the grooves | D.the speed of the car | 小题3:The underlined word “optimal” in the passage might mean .A.fastest | B.possible | C.best | D.suitable | 小题4:In order to hear the music well, you have to .A.drive very fast | B.drive slowly | C.open the windows wide | D.keep the windows closed | 小题5:What’s the best title of the passage?A.A New Type of Music | B.Melody Roads in Japan | C.A Musical Road Surface | D.A New Invention in J |

In the future your automobile(汽车) will run on water instead of gas! You will be able to buy a supercomputer that fits in your pocket! You might even drive a flying car! For each prediction that has come true today, several others have missed by a mile. Many of these predictions didn’t consider how people would want to use the technology, or if people really needed it in their lives or not. Let’s look at some predictions from the not-too-distant past. Robot Helpers Where’s the robot in my kitchen? Nowhere, of course. And he’s probably not coming anytime soon. Robots do exist today, but mostly in factories and other manufacturing environments. Back in the 1950s, however, people said that by now personal robots would be in most people’s homes. So why hasn’t it happened? Probably because robots are still too expensive and clumsy. And maybe the idea of robots cooking our dinners and washing our clothes is just too weird. At home we seem to be doing fine without them. Telephones of Tomorrow In 1964 an American company introduced the video telephone. They said by the year 2000 most people would have a video phone in their homes. But of course the idea hasn’t caught on yet. Why? The technology worked fine, but it over—looked something obvious: people’s desire for privacy(隐私). Would you want to have a video phone conversation with someone after you just step out of the shower(淋浴)? Probably not---it could be embarrassing! Just because a technology available doesn’t always mean people will want to use it. And finally, how about that crazy prediction of the flying car? It’s not so crazy anymore! But a flying car remains one of the most fascinating technology ideas to capture our imagination. Keep watching the news, or perhaps the sky outside your window, to see what the future will bring. 小题1: The whole passage is mainly about ________________.A.predictions that have come true. | B.predictions that haven’t come true. | C.why predictions don’t come true easily. | D.what technology will bring about. | 小题2: The author of this passage won’t believe that _________________.A.predictions needn’t consider people’s practical use of technology. | B.the future isn’t always easy to guess. | C.not all past predictions have come true. | D.many of the high—tech things our parents thought we’d be using by now | simply never appeared. 小题3: The underlined word “weird” probably means __________.A.wonderful | B.stupid | C.practical | D.strange | 小题4: What does the author think of the flying car?A.It is too difficult to imagine. | B.It is too crazy an idea. | C.It is likely to be made. | D.It is often reported in the news. |
