Two&thirds of the world's major rivers have now been disrupted with more than 50,000 dams in an attempt to& store water and provide power.In the US，there are more than 85,000 dams，disrupting large and small rivers，and in most cases transforming natural flow.The most famous of these，the Hoover Dam，constructed in the 1930s，is mainly responsible for the fact that the Colorado River no longer reaches the ocean.Dams，besides all their attractive benefits，also have negative impacts.Creating a reservoir means a large area must munities may lose their land，houses and culturally important sites.Environmentally，the new reservoir can be a paradise for wildlife，especially birds；however，it can cause greenhouse gas emissions and poison the water.Also，the dramatic rise and fall of water levels during dam releases is too extreme for plants and animals to cope with，resulting in dead zones around the shores of reservoirs.Fish that lay their eggs in the shallows，for example，may find a few hours later that those sites are high and dry.Downstream(在下游方向)of a dam，the flow may be reduced so that farmers cannot irrigate their fields.Many rivers run through national borders，which may cause conflict over precious water.Disputes have been continuing between India and Pakistan，and Turkey，Syria and Iraq，for example.Dams don't just block the flow of water.They also prevent fish migrations，and dams are a barrier to sediment(沉淀物)flows.Instead of rushing downriver，sediments get backed up against the dam wall，which causes the reservoir level to increase over time.However，sediments which are rich in nutrients have become a problem.The fertility of the entire system can be influenced，with soils lost during seasonal rains not being replaced.Perhaps the biggest problem can be seen in deltas，which are sinking into the oceans.Groundwater is being extracted to feed the city，causing the city to sink，and sediments washed away by the ocean are no longer being replaced.The result is that sea level rises in cities from Shanghai to Alexandria.小题1:The Hoover Dam is mentioned in the passage in order to show________.A．dams play an important role in our lifeB．dams have impacted the flow of the riversC．dams make people lose their land and housesD．dams have many benefits as well as side effects小题2:What effects does creating a reservoir have on people's life?a．People will see fewer birds on the sides of the rivers.b．Farmers will have less water to irrigate their fields.c．Visitors can't visit some cultural relics any more.d．More conflicts and wars over water will break out.e．More kinds of fish will become extinct in future.A．a，c　B．c，eC．b，e　D．b，c小题3:With many dams built across the rivers，fish ________.A．will find more places to lay their eggsB．will face a dangerous habitatC．will be fed on more sediments rich in nutrientsD．will find it easier to deal with the rise of water小题4:How can dams influence large cities like Shanghai?A．Their entire system will be influenced.B．The rainy season will last longer.C．They will lie below sea level in future.D．Rich soils will be washed away.小题5:What does the passage mainly talk about?A．Environmental loss of dams.B．Cultural loss of dams.C．Economic gain of dams.D．Environmental benefits of dams.

(2013·高考北京卷，D)People who multitask all the time may be the worst at doing two things at once，a new research suggests.The findings，based on performances and self&evaluations by about 275 college students，indicate that many people multitask not out of a desire to increase productivity，but because they are easily distracted (分心) and can’t focus on one activity.And “those people turn out to be the worst at handling different things，”said David Sanbonmatsu，a psychologist at the University of Utah.Sanbonmatsu and his colleagues gave the students a set of tests and asked them to report how often they multitasked，how good they thought they were at it，and how sensation&seeking (寻求刺激) or impulsive (冲动)they were.They then evaluated the participants’multitasking ability with a tricky mental task that required the students to do simple mathematical calculations while remembering a set of letters.Not surprisingly，the scientists said，most people thought they were better than average at multitasking，and those who thought they were better at it were more likely to report using a cellphone while driving or viewing multiple kinds of media at once.But those who frequently deal with many things at the same time were found to perform the worst at the actual multitasking test.They also were more likely to admit to sensation&seeking and impulsive behavior，which connects with how easily people get bored and distracted.“People multitask not because it’s going to lead to greater productivity，but because they’re distractible，and they get sucked into things that are not as important，”Sanbonmatsu said.Adam Gazzaley，a researcher at the University of California，San Francisco，who was not a member of the research group，said one limitation of the study was that it couldn’t find out whether people who start out less focused tend toward multitasking or whether people’s recognizing and understanding abilities change as a result of multitasking.The findings do suggest，however，why the sensation&seekers who multitask the most may enjoy risky distracted driving.“People who are multitasking are generally less sensitive to risky situations.”said Paul Atchley，another researcher not in the group.“This may partly explain why people go in for these situations even though they’re dangerous.”小题1:The research led by Sanbonmatsu indicates that people who multitask________.A．seek high productivity constantlyB．prefer handling different things when getting boredC．are more focused when doing many things at a timeD．have the poorest results in doing various things at the same time小题2:When Sanbonmatsu and his colleagues conducted their research，they________.A．assessed the multitasking ability of the studentsB．evaluated the academic achievements of the studentsC．analyzed the effects of the participants’tricky mental tasksD．measured the changes of the students’understanding ability小题3:According to Sanbonmatsu，people multitask because of their________.A．limited power in calculationB．interests in doing things differentlyC．inability to concentrate on one taskD．impulsive desire to try new things小题4:From the last paragraph，we can learn that multitaskers usually________.A．drive very skillfullyB．go in for difficult tasksC．fail to react quickly to potential dangersD．refuse to explain the reasons for their behavior

techniques , but he admitted there would be difficulties in meeting his goal .“ For example , if you run out of ink while printing on paper , you will throw that paper away . But you cannot throw half-completed buildings away if your material gets stuck , ” he said . Although the printed house is not available to visit , there is a chance for people in Shanghai to see items printed in 3D. The Belgium-based company Materialise NV held a 3D printing exhibition in Shanghai that started in late 2012 and ended in the middle of 2013 . The company is eager to show Asia what is possible with 3D printing .“ All the pieces shown here are what cannot be made through traditional techniques . A good example of this customization is hearing aids . More than 10 million people already use 3D printed hearing aids, all made according to the size of their ears , ” said Wim Michiels , executive vice-president at Materialise NV .“ You can produce anything whenever and wherever you like . You don’t need to set up production lines for pieces that only need a limited amount of products . Setting up a production line is a lot of work . It takes a long time and is very expensive for a limited number of pieces , ” said Michiels .Kim Francois , managing director of Materialise China , said their European and American clients have already taken the next step toward additive manufacturing with small series production such as hearing aids .小题1:What is mainly talked about in the text ?A.

Boys at the top of the pecking order(长幼次序) either by birth or because their older brothers died score higher on IQ tests than their younger brothers.& Norwegian researchers now report that it’s a matter of what they call social rank in the family that gives the first born the highest scores or, if the first born had died young, the next oldest.& Kristensen and Bjerkedal studied the IQ test results of 241,310 Norwegian men drafted(征兵) into the armed forces between 1967 and 1976. All were aged 18 or 19 at the time.& The average IQ of first-born men was 103.2, they found second-born men averaged 101.2, but second-born men whose older brother died young scored 102.9. And for third-borns, the average was 100.0. But if both older brothers died young，the third-born score rose to 102.6. The findings provide “evidence that the relation between birth order and IQ score is dependent on the social rank in the family and not birth order as such.” they concluded. It’s an issue that has been hotly discussed since at least 1874,when Sir Francis Galton reported that men in noticeable positions tended to be firstborns more often than would have been statistically (统计) expected.
Since then, several studies have reported higher intelligence scores for firstborns, while other analyses have questioned those findings and the methods of those reports.
“These two researchers prove that how study participants(参与者) were raised, not how they were born, is what actually influences their IQs,” said Sulloway, an American professor, who was not part of the research team. “The elder child pulls ahead,” he said, “perhaps as a result of learning gained through the process of tutoring younger brothers and sisters”.& “The older child benefits by having to organize and express its thoughts to tutor youngsters”, he said, “while the later born children may have no one to tutor.”小题1:According to Norwegain researchers’ finding, which of the following is linked to boys’ IQ?A．Birth orderB．Position in the family C．Parents’ social rankD．Educational experience小题2:What does the sentence “It’s an issue that has been hotly discussed” underlined in Paragraph 6 mean? A．Many people take interest in IQ study. B．IQ study has gone further and further. C．Many people do research on boys’ IQ. D．Opinions are divided on the conclusion.小题3:According to Kristensen and Bjerkedal’s test results, parents can make youngsters smarter by ________.A．treating them as the oldest childB．teaching them as the oldest childC．talking to them as much as possibleD．encouraging them to express thoughts

Hu Li's heart sank due to the color of the air.Driving 140 kilometers from Tianjin City to Beijing last week，she held her breath as the air became a charcoal grey haze(炭灰色的阴霾)．The 39&year&old businesswoman has lived in Beijing for a decade，and this past month，she said，brought the worst air pollution she has ever seen.It gave her husband a cough and left her seven&year&old daughter housebound(足不出户)．“My husband as well as I is working here，so we have no choice，” she said.“But if we had a choice，we'd like to escape from Beijing.”The extended heavy pollution over the last month，which caused punishment in return for a day last week－called the “airpocalypse” by internet users－ has largely changed the way that Chinese think about the country's air.On one day，pollution levels were 30 times higher than levels considered safe by the World Health Organization (WHO)．Flights were cancelled.Roads were closed.One hospital in east Beijing reported they had treated more than 900 children for breathing issues.Bloomberg found that for most of January，Beijing's air was worse than that of an airport smoking area.The smog's(烟雾) most threatening aspect is its high concentration(浓度) of PM 2.5 － particulate matter that is small enough to breathe deep into the lungs and enter the bloodstream，causing breathing infections，lung cancer and possibly damaging children's development.The WHO has estimated that outdoor air pollution accounts for two million deaths per year，65% of them in Asia.小题1:Which conclusion can we draw from the first paragraph?A．Hu Li is living in Beijing.B．Hu Li traveled to Tianjin for business.C．The haze is harmful to people.D．The pollution is the worst in Beijing's history.小题2:The haze affected people mainly in________．A．the way they traveledB．the opinion about national airC．the way they lived their lifeD．the life style of internet小题3:From the passage we know high concentration of PM 2.5________．A．can lead to chokeB．can cause heart cancerC．will damage children's developmentD．will damage people's organ小题4:What's the best title for the passage?A．Hu Li's attitudes to Beijing's hazeB．The damages of Beijing's hazeC．WHO suggests improving Beijing's airD．What caused air pollution in Beijing

Today, when a fire breaks out, you can be sure a citizen with a cell-phone camera has posted it to Facebook or Twitter, or sent it to the media. But up to now, that citizen has not been able to easily send images and details of what is happening to the people who need it most: police, firefighters and building-security people who must respond, and whose ability to help is often measured in minutes, if not seconds. That's about to change. A one-year old company called Elerts has developed a system that's designed to mobile and social technologies to speed the flow of information between citizens and emergency workers in time of danger. The system involves free mobile applications—iPhone and iPad app（应用软件）is available now—that eyewitnesses can use to report incidents and get public-safety warnings. And Elerts is offering a management console（控制台）for security firms and universities to receive the reports and distribute warnings and instructions, like a map with the best evacuation route（疏散路线）. The service is the brainchild of Chris Russo, deputy fire chief in the coastal town of Hull, Mass. As mobile communications sped up, he grew increasingly frustrated by his inability to communicate effectively with colleagues and the public, particularly with people who are at the scene and might be able to provide help. "Remembering situations when communications failed puts a pit in my stomach," Mr. Russo says. Last summer, he was in a search at a beach for a missing boy, who went into a bathhouse but didn't come out. First responders feared an abduction （绑架） on the beach or shark attack. The child's mother, who didn't speak English well, was so sad that she couldn't remember what color shorts he had on. Mr. Russo had no photo of the child, and no ability to turn to beachgoers. Two long hours later, the boy was spotted by a low-flying helicopter lost and alone on the beach crying—a lucky break. "If 5 percent of beachgoers had an app to receive a message and send in sightings of a lost boy, the happy ending might have come much sooner," Mr. Russo said.小题1:What is the passage mainly about?A．A moving story of Chris Russo．B．An app for reporting emergency． C．A cell-phone instant service．D．An app for firm management．小题2:What does the underlined part in Paragraph 4 most probably mean?A．Makes me feel frustrated．B．Causes a stomachache．C．Arouses my interest．D．Leaves a hole in my stomach．小题3:We can infer from the passage that emergency workers ____．A．have to carry out rescue work in minutesB．must send images and details immediatelyC．need images and detailed information badly D．have to turn to Facebook and Twitter for details小题4:The author takes Chris Russo's experience as an example to ____．A．advertise his creativity in communicationB．show readers the working principle of the new systemC．make the passage more interesting to readD．inform readers how Russo got the idea of the service

Did anyone find the names of “Great Britain”, “the United Kingdom”, “England” and “the British commonwealth” which have the same meaning? Strictly speaking, these names all refer to something different. None of them are exactly the same as any of the others. The British isles refer to the main islands and several thousand small ones as well, which you can see on the map. Great Britain, or Britain, refers to the larger of the two main islands. But the word “Britain” is often used as a short form for the United Kingdom or you call it the UK. Now as for England, it refers simply to the largest of the three countries on the island of Great Britain. The United Kingdom is the name of the state and the official name of the country, which many people popularly refer to England. Finally, the Britain commonwealth is the usual name for what is left of the British Empire (帝国). This change shows the weakening of British Empire and the rising of the national liberation movements throughout the world today. 小题1:According to the passage, we know that _____________. A．Great Britain has the same meaning as BritainB．all the names refer to EnglandC．the United Kingdom has the same meaning as Britain or EnglandD．all the names in the first paragraph have the same meaning小题2: It is clear that the British isles refer to _____________.

About ten men in every hundred suffer from color blindness in some way. Women are luckier, only about one in two hundred if affected in this matter. Perhaps, after all, it is safer to be driven by a woman. There are different forms of color blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shades of green. Sometimes a person can’t tell the differences between blue and green. In rare cases an unlucky man sees everything in shades of green--- a strange world in deed. Color blindness in human beings is a strange thing to explain. In a single eye there are millions very small things called “cones”. These help us see in a bright day and tell the differences between colors. There are also millions of “rods”, but these are used for seeing when it is nearly dark. They show us shapes(形状) but not color. Some insects have favorite colors. Mosquitoes like blue but do not like yellow. A red light will not attract insects but a blue lamp will. In similar way human being also have favorite colors. Yet we are lucky. With the aid of cones in our eyes we can see many beautiful colors by day and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colors around us. 小题1:The passage is mainly about ______. A．color and its surprising effects on driversB．women being luckier than man in that fewer of them are color blindC．danger caused by color blindnessD．color blindness and how our eyes tell different colors and shapes小题2:According to the passage, with the help of “cones” we can _____. A．tell different colorsB．see in weak lightC．tell different shapesD．tell orange from yellow小题3:Why do some people say it is safer to be driven by women?A．Women are more careful.B．There are fewer color blind women.C．Women are fonder of driving than men.D．Women are weaker but quicker in thinking.小题4:Which of the following statements about color blind people is true?A．Not all of them have the same problem in recognizing colors. B．None of them can see deep red but all can tell blue from green.C．None of them can tell blue from green but all can see deep red. D．All of them are lucky enough to see everything in shades of green.
