Men have always believed that they are smarter than women. Now, a study has found that while this is certainly true, men also have to deal with the fact that they are also more stupid than the fairer sex.
In the study, scientists measured the IQ of 2500 brothers and sisters and they found an uneven number of men not only in the top two percent, but also in the bottom two percent.
The study's participants were tested on science, maths, English and mechanical abilities.
Though there were twice as many men as women in the smartest group, there were also twice as many men among the dolts.
The aggregate scores of men and women were similar.
One of the study's authors, psychology professor Timothy Bates, said that the phenomenon may be because men have always been expected to be high achievers and women have been restricted to spend more time taking care of their home.
"The female developmental program may be tilted more towards ensuring survival and the safety of the middle ground.," the Daily Mail quoted Professor Bates, of Edinburgh University, as saying.
The research tallies with past results that men were more likely than women to receive first class University degrees or thirds and women secured the seconds.
It has been said that men are more ready to take risk when it comes to academics. Women have always found to be steadier in their learning.
A past study has shown that women are securing more firsts and seconds, while men are continuing to receive more thirds.
The argument for the change is that the increase of coursework at the cost of exams favors women's steady approach.

Can noncombustion (非燃烧) technology create a no-pollution way to drive？Imagine pulling into a service station to fuel up your car. But not at the gas pump or electric battery charger —at the air pump! That’s not hot air, either! The next generation of cars may run on thin air. Wouldn’t that be an incredible way to cut both pollution and dependence on foreign oil?
If you’ve ever inflated a balloon and then let it go, you’ve got the basics to test-drive the amazing MiniCAT, currently being developed by Noteur Development International (MDI), headquartered in Luxembourg. Invented by Formula One racing car designer Guy Negre, this experimental vehicle is unlike any car you’ve ever seen. While your family’s traditional car or SUV draws its horsepower using combustion, the only fuel that MiniCAT needs (CAT stands for Compressed Air Technology) is the air we breathe.
Start with about 25,000 gallons of air. Now, press it all into a space smaller than your school locker—because that’s the size of two super-strong, high-pressure air tanks, made from fiber and fixed beneath the air car.
Confining that much air inside those small tanks generates an internal pressure of over 4,000 pounds per square inch. That’s over 300 times normal air pressure.
When this cold, high-pressure air enters MiniCAT’s unique engine, it interacts(交互作用) with warmer air to create pressure waves that pump the engine’s engineered pistons (活塞) to move the car. MiniCAT’s projected top speed is 60 miles per hour, with a range of 120 miles on a full air supply.
【小题1】What is the passage mainly about?
| A．Ways to cut down air pollution. |
| B．Cars that run on thin air. |
| C．Formula One racing car designer. |
| D．Dependence on foreign oil. |
| A．The name of a car. |
| B．The name of a balloon. |
| C．The name of a car company. |
| D．The name of a car designer. |
| A．Keeping | B．Preventing | C．Pushing | D．Running |
| A．How much pressure the air creates. |
| B．How the car works. |
| C．What the normal air pressure is. |
| D．How the air gets into the engine. |

“Enough” with the multivitamins already. That’s the message from experts behind three new studies that tackled an often debated question: Do daily multivitamins多种维生素make you healthier?
“We believe that the case is closed - supplementing(补充) the diet of well-nourished adults with (most) mineral or vitamin supplements has no clear benefit and might even be harmful,” concluded the authors of the editorial summarizing the new research papers. They urge consumers to not ‘waste’ their money on multivitamins. “The ‘stop wasting your money’ means that perhaps you’re spending money on things that won’t protect you long term,” editorial co-author, Dr. Edgar Miller said, “What will protect you is if you spend the money on fruits, vegetables, nuts, beans, low fat dairy, and things like that. Exercising would probably be a better use of the money.”
The strong message was based on a review of the findings from three studies that tracked multivitamins link to cancer protection, heart health, and brain and cognitive(认知的) measures. The first study looked at vitamin supplementation’s role in preventing chronic(慢性的) disease. The next study looked at whether long-term use of multivitamins would have any effect on slowing cognitive decline. The third study looked specifically at multivitamins and minerals role in preventing heart attack. “The three studies found no difference in rates of chronic disease, heart attack and the need for hospitalization between vitamin-takers and placebo(安慰剂)-takers.” Dr. Edgar Miller stated.
One expert agreed some nutrient-deficient people may still benefit from multivitamins. “There might be an argument to continue taking a multi(vitamin) to replace or supplement your not healthy diet,” Dr. Edgar Miller added. He also notes that vitamins can benefit people with celiac disease and those who are pregnant.
【小题1】This text is likely to be selected from a book of .
| A．medicine | B．education | C．food | D．business |
| A．Vitamins should not be used for chronic disease prevention. Enough is enough. |
| B．Having a balanced diet and exercising would probably be a better way to keep healthy. |
| C．The three studies do not provide support for use of multivitamin supplements. |
| D．Taking vitamins to replace or supplement your healthy diet is necessary. |
| A．Vitamin supplements have proved harmful to the health of adults. |
| B．Vitamin supplements are beneficial in certain conditions. |
| C．Nowadays taking vitamin supplements is common to most people. |
| D．Daily multivitamins will make you healthier. |

Global warming happens when greenhouse gases trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. This is like when heat is trapped in a car. On a hot day, the car gets hotter when it is out in the parking lot. This is because the heat and light from the sun can get into the car, by going through the windows，but it can’t get back out. This is what the greenhouse effect does to the earth .The heat and light can get through the atmosphere, but it can’t get out As a result，the temperature rises.
Sometimes the temperature can change in a way that helps us. The greenhouse effect makes the earth appropriate for people to live on Without it，the earth would be freezing，or it would be burning hot. It would be freezing at night because we would not get the sun’s heat and light .During the day, especially during the summer, it would be burning because the sun would be up with no atmosphere to filter(过滤)it，so people，plants，and animals would be exposed to all the light and heat.
Although the greenhouse effect makes the earth able to have people living on it，if there gets to be too many gases，the each can get unusually warmer, and many plants，animals．and people will die. Plants would die because they would not be able to take the heat .This would cause us to have less food to eat, and it would also limit the food that animals have. With less food for the animals that we need to survive we would even have less food. Gradually, people，plants，and animals would all die of hunger．
People are doing many things to try to stop global warming .One thing is carpooling—driving with someone to a place that you are both going to. Another thing is being more careful about leaving electrical devices turned on. Now, more people are even riding buses or bikes to lower the amount of greenhouse gases in the air .Although adults do many things to help stop global warming, kids call do just as much.
【小题1】By the example given in Paragraph l, the author wants to__________.
| A．explain how global warming happens |
| B．show his feeling in a car in hot summer |
| C．tell us cars are causes of greenhouse gases |
| D．say that I there are greenhouse gases in every car |
| A．light | B．greenhouse effect | C．temperature | D．heat |
| A．IT only traps the heat of the sun. |
| B．It does great harm to humans. |
| C．It makes the earth neither to hot nor too cold. |
| D．It prevents all the light from the sun shining on the earth. |
| A．lf there is greenhouse effect．all the plants will die |
| B．Human beings are likely to disappear from the earth |
| C．Crops can ′t take in the heat lf there is greenhouse effect |
| D．Although greenhouse effect is necessary．Too much of it will cause us to die. |
| A．What kids can do to help stop global warming. |
| B．Who should be responsible for the environmental problems. |

Almost every machine with moving parts has wheels，yet no one knows exactly when the first wheel was invented or what it was used for.We do know，however，that they existed over 5,500 years ago in ancient Asia.
The oldest known transport wheel was discovered in 2002 in Slovenia.It is over 5,100 years old.Evidence suggests that wheels for transport didn’t become popular for a while，though.This could be because animals did a perfectly good job of carrying farming tools and humans around.
But it could also be because of a difficult situation.While wheels need to roll on smooth surfaces，roads with smooth surfaces weren’t going to be constructed until there was plenty of demand for them.Eventually，road surfaces did become smoother，but this difficult situation appeared again a few centuries later.There had been no important changes in wheel and vehicle design before the arrival of modern road design.
In the mid1700s，a Frenchman came up with a new design of road—a base layer(层) of large stones covered with a thin layer of smaller stones.A Scotsman improved on this design in the 1820s and a strong，lasting road surface became a reality.At around the same time，metal hubs (the central part of a wheel)came into being，followed by the pneumatic tyre(充气轮胎) in 1846.Alloy wheels were invented in 1967，sixty years after the appearance of tarmacked roads(柏油路)．As wheel design took off，vehicles got faster and faster. (2013·重庆，C)
【小题1】What might explain why transport wheels didn’t become popular for some time?
| A．Few knew how to use transport wheels. |
| B．Humans carried farming tools just as well. |
| C．Animals were a good means of transport. |

Electric cars are dirty.In fact，not only are they dirty，they might even be more dirty than their gasolinepowered cousins.
People in California love to talk about “zeroemissions vehicles”，but_people_in_California_seem_to_be_clueless_about_where_electricity_comes_from.Power plants mostly use fire to make it.Aside from the new folks who have their roofs covered with solar cells，we get our electricity from generators.Generators are fueled by something—usually coal，oil，but also by heat generated in nuclear power plants.There are a few wind farms and geothermal(地热的) plants as well，but by far we get electricity mainly by burning something.
In other words，those “zeroemissions” cars are likely coalburning cars.It’s just because the coal is burned somewhere else that it looks clean.It is not.It’s as if the California Greens are covering their eyes—“If I can’t see it，it’s not happening.” Gasoline is an incredibly efficient way to power a vehicle；a gallon of gas has a lot of energy in it.But when you take that gas(or another fuel) and first use it to make electricity，you waste a nice part of that energy，mostly in the form of wasted heat—at the generator，through the transmission(传送) lines，etc.
A gallon of gas may propel your car 25 miles.But the electricity you get from that gallon of gas won’t get you nearly as far—so electric cars burn more fuel than gaspowered ones.If our electricity came mostly from nukes；or geothermal，or hydro，or solar，or wind，then an electric car truly would be clean.But for political，technical，and economic reasons，we don’t use much of those energy sources.
In addition，electric cars’ batteries which are poisonous for a long time will eventually end up in a landfill.And finally，when cars are the polluters，the pollution is spread across all the roads.When it’s a power plant，though，all the junk is in one place.Nature is very good at cleaning up when things are too concentrated，but it takes a lot longer when all the garbage is in one spot.

Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now a new study has confirmed that atmospheric CO2 is also affecting the ocean chemistry and potentially harming sea life.
Montana State University scientist Robert Dore has been researching the water in the Pacific Ocean for almost two decades. "We've been going to the same spot in the Pacific Ocean, and we try and characterize long-term change in the open ocean environment. And one of the key things that we measure is COx levels. And We've been able to record this increasing quantity of atmospheric CO, into the ocean. "Scientists expected that as atmospheric CO2 increased, more and一 more of the carbon dioxide would be absorbed into the ocean, affecting the chemical balance of the sea water, with a potentially harmful impact on shellfish and coral in particular.
"As carbon dioxide dissolves in the water, or seawater in this case, it forms a weak acid, carbonic acid," Dore explains. "And therefore, as the concentration of CO2 in the atmosphere goes up and that exchanges with the surface seawater, it drives the pH down, and makes it more acidic."
The seawater samples Dow and his colleagues have analyzed confirm what the theory predicts. The effect was particular striking at about 250 meters down, and again at 500 meters. Dore and his colleagues came up with two possible explanations. It could be that surface water picked up CO2 and then moved to those depths. Or there could be a biological explanation.
"It's important to realize that the oceans are really becoming acidic. And it can have negative impacts on a whole variety of sea life from fish to coral. It’s potentially catastrophic."
【小题1】What can be the best title of the passage?
| A．Sea Life Facing Danger | B．Scientist Researching Seawater |
| C．Oceans Becoming More Acidic | D．Climate Change Affecting Seawater |
| A．more corals will appear in the sea |

These days it’s cheaper to throw that broken DVD player, cell-phone or TV out and buy a new one. This “ replace-rather-than-repair” mentality is polluting the planet with electronic waste. According to the UN Environment Program, we are throwing away an estimated 50 million metric tonnes of electronics waste (e-waste) per year. But this is not ordinary garbage. Our electronics leak harmful heavy metals — such as mercury and arsenic — along with equally poisonous chemicals that end up in our soil and eventually our water.
You’ve probably participated in a community recycling event and left feeling good about shipping off that old computer to be recycled. Chances are it was shipped overseas where it’s polluting someone else’community.
Guiyu city in Southeastern China has become known as the e-waste city where low-paid workers use whatever means available to remove electronics in hopes of recovering the copper, microchips, aluminum, gold and silver and plastic that can be resold. Any leftover waste is simply thrown into the nearby river or piled up high in the streets, poisoning the children growing up here.
So what can you do with your e-waste? Robert Houghton, President and founder of Redemtech, an asset management and recovery firm, recommends you vote with your dollar. Buy from companies who have a take-back program that guarantees your discarde electronics are handled proper.
“ Consumers want to do business with companies who are demonstrably good with corporate responsibility and dealing with e-waste, ” said Houghton.
There are plenty of charitable organizations that will take your used electronics and donate them for charitable causes:
? Electronic Recycling Association (Canada) (ERA) collects old computers for donation to libraries and other organizations across Canada.
? eBay’s Rethink Initiative pairs up consumers with businesses that refurbish (再磨光)old computers for donation.
? TechSoup has a thorough listing of resources for those who would like to donate or recycle hardware，buy recycled hardware or find a refurbisher.
? The Charitable Recycling Program accepts all cell-phones and has a listing of charities it helps with its program.
? Call2 Recycle has set up drop off points across Canada in a number of stores. You can drop off your cell-phone and also your rechargeable batteries from handheld electronic products.
【小题1】When there is something wrong with electronics, what is a popular trend among people nowadays?
| A．To keep a DIY way. | B．To put them away themselves. |
| C．To purchase what they like. | D．To donate them to charities. |
| A．there is an ideal place in the world for e-waste |
| B．there is a good example in the world for recycling |
| C．the recycling events in Canada benefit people overseas |
| D．people should find a scientific and thorough way to recycle |
| A．The UN Environment Program. |
| B．Consumers who buy electronics. |

It's a fact that we all dream. Some dreams seem to last for hours, others only for seconds. Some of us have strange dreams, some have interesting dreams, and some of us have unpleasant dreams. Tests in the 1980s showed that these dreams occur within 90-minute cycles, each cycle made up of six stages. In the last stage people experience rapid eye movement, known as REM, and it is in this stage that dreaming takes place. Eighty percent of people who were woken during this sixth stage could easily remember their dreams. On the other hand, when during the first five stages (NREM), only seven percent could describe a dream.
However, of these same people woken during the first five stages, 74% were able to remember thinking activity, although they would not call it a dream. NerysDee, who has written about dreams in a book called "Your Dreams and What They Mean" says: "Perhaps during NREM sleep we are sorting out our outer mundane problems, but in REM sleep we are dealing with inside matters." She also makes the following statement about 90-minute cycle: It may also prove the reason why insomniacs who wake in the middle of the night find it impossible to get to sleep again for at least an hour and a half. In other words, until they have missed out one complete 90-minute sleep period.
【小题1】Which of the following statements about dreams is TRUE?
| A．Everyone dreams but very few can recall what they dream. |
| B．Some people have long dreams and others have very short ones. |
| C．People can only remember unpleasant dreams. |
| D．More than eighty percent of people can remember their dreams. |
| A．between each 90-minute cycle |
| B．at any time during 90-minute cycles |
| C．during the first five stages of 90-minute cycles |
| D．in the last stage of 90-minute cycles |
| A．hardly remember their dreams |
| B．easily remember their dreams |
| C．only remember their dreams |
| D．partly remember their thinking activity |
| A．can always remember their dreams |
| B．have trouble getting into sleep at night |
| C．experience rapid eye movement |
| D．usually wake after each 90-minute sleep period |
