(2013·高考安徽卷,B)Using too much water or throwingrubbish into our rivers are clear ways that humans can put our water supply in danger,but we also affect our water supply in less obvious ways.You may wonder how paving(鋪砌) a road can lead to less useable fresh water.A major part of the water we use every day is groundwater.Groundwater does not come from lakes or rivers.It comes from underground.The more roads and parking lots we pave,the less water can flow into the ground to become groundwater.
Human activity is not responsible for all water shortages(短缺).Drier climates are of course more likely to have droughts(干旱) than areas with more rainfall,but in any case,good management can help to make sure there is enough water to meet our basic needs.
Thinking about the way we use water every day can make a big difference,too.In the United States,a family of four can use 1.5 tons of water a day! This shows how much we depend on water to live,but there’s a lot we can do to lower the number.
You can take steps to save water in your home.To start with,use the same glass for your drinking water all day.Wash it only once a day.Run your dishwasher (洗碗機)only when it is full.Help your parents fix any leaks in your home.You can even help to keep our water supply clean by recycling batteries instead of throwing them away.
【小題1】Which of the following is most likely to lead to less groundwater?
A.Using river water. |
B.Throwing batteries away. |
C.Paving parking lots. |
D.Throwing rubbish into lakes. |
A.All water shortages are due to human behavior. |
B.It takes a lot of effort to meet our water needs. |
C.There is much we can do to reduce family size. |
D.The average family in America makes proper use of water. |
A.show us how to fix leaks at home |
B.tell us how to run a dishwasher |
C.prove what drinking glass is best for us |
D.suggest what we do to save water at home |
A.Why paving roads reduces our water |
B.how much we depend on water to live |
C.why droughts occur more in dry climates |
D.how human activity affects our water supply |

Many people believe that teaching children music makes them smarter, better able to learn new things. But the organizers of a new study say there's no scientific evidence that early musical training affects the intelligence of young people.
An estimated 80 percent of American adults think music lessons improve children's abilily to learn or their performance in school. They say that the satisfaction for learning to play a new song helps a child express creativity.
Researchers at Harvard University, however, have found that there's one thing musical training does not do. They say it does not make children more intelligent. Samuel Mehr is a graduate student at Harvard's School of Education. He said it is wrong to think that learning to play a musical instrument improves a child's intellectual development. He says the evidence comes from studies that measured the mental ability of two groups of 4-year-olds and their parents. One group attended music class, the other went to a class that places importance on the visual arts—arts that can be seen.
"The evidence there is 'no'. We found no evidence for any advantage on any of these tests for the kids participating in these music clases," said Mehr.Samuel Mehr says researchers have carried out many studies in an effort to learn whether musical training can make children smarter. He says the results have been mixed. He says only one study seems to show a small percentage increase in IQ, intellectual scores among students after one year of music lessons. He does not believe that IQ is a good measure of child's intelligence. He says researchers in his study compared how well children in the musical training group did on mental processing tasks or projects, then the results were compared to those of children who did not take lessons. There was no evidence that the musical training group did much better on the mental tasks than the other group.
The researchers comfirmed the results with a larger group of children and their parents.Mr Mehr says music lessons may not offer children a fast easy way to gain entry to the best schools later of their life. But he says the training is still important for cultural reasons. In his words, "We teach music because music is important for us."
【小題1】According to the new study, musical training______.
A.makes children smarter |
B.helps a child express creativity |
C.does not make children more intelligent |
D.improve children's ability to learn in school |
A.the children who attended music class are smarter than those who attended arts class |
B.IQ is a good measure of a child's intelligence |
C.we needn't to teach children music |
D.music training is still important for cultural reasons |

A smart phone (智能手機) is a mobile phone built on a mobile operating system, with more advanced computing abilities than a common phone. The first smart phones enabled the users to send and receive emails. Later models added the function of portable media players, pocket video cameras, and GPS navigation (導航) units to form one multi-use device. Many modern smart phones also include touchscreens and web browsers (瀏覽器) that display web pages.
A recent report says we spend an average of two hours and 40 minutes each day looking at a smart phone. That doesn’t mean making calls, but playing phone games and browsing the Web.
Nowadays we always find people checking emails in a restaurant, taking a picture of the food when it arrives, or checking a message during a conversation instead of traditional communication. It’s no secret that our lives are being affected by our smart phones obsession.
However, this phenomenon has never been presented so vividly as in the short YouTube film I Forgot My Phone. Despite only being online for a few days, it's already been viewed more than 10.5 million times. Whether it will be screened in the cinema remains to be seen.
Ironically, YouTube’s data show that the site gets a billion views per day from mobile devices, so a lot of those people watched it on their phones.
The short film, written by and starring actress Charlene Deguzman, shows groups of people in various social situations, the majority of whom are absorbed in their phones instead of the world around them. To a certain extent, we all do it.
【小題1】People prefer a smart phone to a common one, because the latter only can help us ______.
A.check emails | B.send messages | C.find the destination | D.watch a video |
A.devotion | B.contribution | C.a(chǎn)ddiction | D.emotion |
A.People spend as average of two hours and 40 minutes each day using smart phones. |
B.The film hasn’t been put on in the cinema. |
C.The film is written by an actor named Charlene Deguzman. |
D.The film has already been viewed more than 105 million times in the first few days. |
A.encouraged | B.depressed | C.proud | D.satisfied |

The United States is not part of the Kyoto Protocol.But since 2005 more than 1,000 mayors across the country have agreed to sign their own version of the protocol.
It is called the United States Conference of Mayors' Climate Protection Agreement.Local leaders have agreed to follow the suggestions of the Kyoto Protocol in their communities.They have also agreed to urge state and federal governments to follow these suggestions.One goal is to reduce air pollution to the 1990 levels by 2012.
A “green” city might work on several kinds of environmental goals and programs.These include air quality,reducing electricity use, green building, public health, the reuse of materials, water quality and clean transportation.
The Natural Resources Defense Council works to protect the environment through action, law and science.One of its online projects is called Smarter Cities, which lists some cities that have made important environmental steps.
Washington,D.C.is also a leading city for green roofs,with over 92,000 square meters of green rooftops.The city also launched a program called “Skip the Bag,Save the River.”Stores charge people a fivecent tax for using plastic or paper shopping bags instead of reusable bags.Money from the tax will be used to clean up a local river.
New York City is using water as a renewable energy source.For several years, the city has experimented with water in the East River to create energy.Officials operating the program recently asked for permission to put into place 30 river turbine devices.
The people of Portland, Oregon are among the top recyclers in the nation.People living there recycle over half of the waste they throw out.The city has also worked to provide green transportation by providing safe bike paths and free parking spaces where electric cars can get recharged.
In Oakland, California, you can ride on one of several public hydrogenpowered(氫氣作燃料的) buses.These buses release zero pollution into the air.However,they cost about five times more than common buses.

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(炭灰色的陰霾).The 39yearold 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 sevenyearold daughter housebound(足不出戶).“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(煙霧) most threatening aspect is its high concentration(濃度) 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.
【小題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. |
A.the way they traveled |

Yawning sends out certain messages -either “Oh ,this movie is so boring” or “I probably need to get some sleep”. But did you know that a yawn can also help your brain to cool down when it is overheated?
A new study, led by a research team at Princeton University, has indicated that yawning could be the brain’s natural way of regulating temperature. People yawn more often when the temperature outdoors is lower than their body temperature but are less likely to yawn when it is hotter outdoors, according to Sciencedaily. com.
The research team did an experiment on 160 people, 80 in summer and 80 in winter, to examine how often they yawned at different air temperatures. The study found that people yawned more often in winter than in summer. Scientists say that when the air temperature is lower outside the body, there is heat exchange between the overheated brain and the cool air. But when the air temperature is higher than or equal to the body, people are less likely to yawn because the hot air they breathe in will make the brain even hotter.
When people yawn, their jaw is also stretched ,which increases blood flow and may also help cool the brain
The study showed that the amount someone yawned could be related to the amount of time they spent outside. The longer they spent outside in summer, the less they yawned. Nearly 40 percent of participants yawned within their first five minutes outside, but after that the percentage was reduced to less than 10 percent.
However, the result was the opposite in winter. The number of people who yawned increased when they spent more than five minutes outdoors. But the change was only slight compared to summertime.
According to Gallup, this is the first report to show that yawning frequencies change depending on season. This could help us to understand better the way our brains work. It may also help us understand the reason why frequent yawning can sometimes be a sign of brain disease.
【小題1】The purpose of the experiment is ______.
A. to prove people yawn in winter and in summer equally |
B. to indicate brain can regulate temperature naturally |
C. to find the frequency of people’s yawning |
D. to show the real reason why people yawn |
A. longer outdoor summertime results in more yawns |
B. yawning frequency changes with outdoor time |
C. yawning frequency increases with outdoor time |
D. longer outdoor wintertime leads to fewer yawns |
A. Yawning Is A Sign of Brain Disease |
B. Yawning Carries Some Information |
C. Yawning Benefits Your Body |
D. Yawning Cools Your Brain |

The first flights of the new airlines that will take tourists into space are ready to take off in 2012, and getting a seat on one is not all that different from booking a trip someplace on Earth. You can sign up on the website of, say, Virgin Galactic,the most wellknown of the new space tourism companies, or go to an approved travel agency and put down a large deposit. Soon you will be able to buy travel insurance,just as you can for any other vacation.
Until now,space tourism has been limited to the ultrawealthy. Just seven people have paid tens of millions of dollars each for a trip to the International Space Station aboard a Russian rocket.
But that could change this year, when Virgin Galactic intends to start offering flights just beyond the space barrier on a rocket ship it has built, featuring five minutes of weightlessness during a twoandahalfhour tour. At $ 200,000 a seat, this will open the final frontier to far more people.
At least two other specialty airlines have jumped in as well, taking reservations and deposits for future space flights.Allianz, the big insurer, will introduce an insurance product in 2012, lending space tourism the trappings of the regular travel industry.
“Just to be able to sell space travel as a regular part of your business, really, just how cool is that?” said Lynda Turley Garrett, president of Alpine Travel of Saratoga, Calif.,who is one of 58 accredited space agents for Virgin Galactic in the United States.
In five years,Ms.Garrett has sold three seats. But she expects that to change once passengers start going up and coming down to tell their friends. “By 2017,it'll be just like scheduling a flight to L.A.,” Ms.Garrett predicted.
【小題1】If you want to book a flight to space in 2012, you can________.
A.go to any travel agency |
B.telephone Virgin Galactic |
C.pay a visit to Allianz |
D.sign up on the website of Virgin Galactic |
A.only the extremely rich people can afford the space trip |
B.seven people have paid tens of millions of dollars for a space trip |
C.Russia is the first country to build the space station |
D.ordinary people are not allowed to take space tour |
A.It is one of the approved space agencies. |

Play allows children to use their creativity while developing their imagination and physical, cognitive (認知的), and emotional strength. Play is important to healthy brain development. Play allows children to create and explore a world they can master, conquering their fears while practicing adult roles. Undirected play allows children to learn how to work in groups, to share, to negotiate, and to resolve conflicts.
Ideally, much of play involves adults, but when play is controlled by adults, children acquiesce (順從) to adult rules and concerns and lose some of the benefits play offers them, particularly in developing creativity, leadership, and group skills. In contrast to passive entertainment, play builds active, healthy bodies. In fact, it has been suggested that encouraging unstructured play may be an exceptional way to increase physical activity levels in children, which is one important strategy in the resolution of the obesity problem.
Children’s development is critically influenced by appropriate, affective relationships with loving and consistent caregivers as they relate to children through play. When parents observe their children in play or join with them in child-driven play, they are given a unique opportunity to see the world from their children’s vantage point as the child navigates a world perfectly created just to fit his or her needs. The interactions that occur through play tell children that parents are fully paying attention to them and help to build enduring relationships. Parents who have the opportunity to look at their children’s world learn to communicate more effectively with their children and are given another setting to offer guidance. Less verbal children may be able to express their views, giving their parents an opportunity to gain a fuller understanding of their perspective. Quite simply, play offers parents a wonderful opportunity to engage fully with their children.
Play is essential to the academic environment. It ensures that the school setting attends to the social and emotional development of children as well as their cognitive development. It has been shown to help children adjust to the school setting and even to strengthen children’s learning willingness. Social-emotional learning is best integrated (融合) with academic learning; it is concerning if some of the forces that enhance children’s ability to learn are improved at the expense of others. Play and unscheduled time that allow for peer interactions are important components of social-emotional learning.
【小題1】Compared with undirected play, play which is controlled by adults ________.
A.doesn’t benefit the children at all |
B.doesn’t help develop leadership and group skills |
C.makes children become more active |
D.helps increase physical activity levels |
A.play offers parents a good chance to establish good relationships with children |
B.children’s development is greatly influenced by relationships with parents |
C.play helps children better express their views |
D.play offers parents a unique opportunity to see the world from a different perspective |
A.play can’t help children become adapted to the school setting |
B.play makes social-emotional learning and academic learning separated |
C.play is beneficial to social-emotional learning as well as academic learning |
D.it is necessary to strengthen children’s academic development at the expense of others |
A.Undirected play can help children develop team spirit. |
B.Play can improve children’s willingness to learn. |
C.Play helps adults gain a better understanding of the children’s thoughts. |
D.Adults shouldn’t be involved in children’s play. |

Having a child may improve a woman’s memory, a new study suggests.
In the study, women who were new mothers scored better on tests of visuospatial memory – the ability to understand and remember information about their surroundings—compared with women who didn’t have children.
The findings contradicts the old belief that women develop“baby brain" or a decline in memory and cognitive(認知的) function, after they have kids, said study researcher Melissa Santiago, a doctoral student at Carlos Albizu University in Miami. “You don’t have to feel that because you have kids, your memory isn’t the same," Santiago said.
The study was small, and the findings will have to be tested in larger groups of people, Santiago said.
Previous studies on the topic have had mixed results—some showed motherhood hurts cognition, and others showed the opposite. Studies on rats show those with pups have better memory than those without offspring.
Santiago analyzed information from 35 first-time mothers whose children were ages 10 to 24 months, and 35 women who had never been pregnant. Both groups scored similarly on intelligence tests. The average age of mothers was 29 and the average age of never-pregnant women was 27.
To test visuospatial memory, the women were shown a paper containing six symbols for 10 seconds, and then asked to draw what they remembered. This task was repeated several times. The first time women were shown the paper, both groups remembered about the same amount. But on the second and third pass, mothers performed better than those without children, indicating that the mothers collected more information each time than the other women.
Later, the women were shown a variety of different symbols, and asked to remember which ones were presented on the earlier task. Mothers did not make a mistake in this task—they remembered every symbol correctly—but those without children made one or two errors, Santiago said.
【小題1】 How did Santiago lead to the findings?
A.By observation. | B.By comparison. |
C.By analyzing intelligence tests. | D.By asking women questions. |
A.The study received little attention. |
B.The study has just started. |
C.The study was carried out among a small group of people. |
D.A small group of researchers were involved in the study. |
A.Ways to test visuospatial memory. |
B.Why having kids improves memory. |
C.How young mothers are different from never-pregnant women. |
D.The negative effects that worries of women without children have. |
A.may cause a heated discussion among parents |
B.may cause an increase in the birth rate |
C.a(chǎn)re tested by previous similar studies |
D.a(chǎn)re encouraging news for mothers |
