potatoesfor vegetables,fish and meat.More recently the trend of swapping spaghetti forvegetables has been 28by clean-eating experts.But now a_29review and analysis of 30 studies by Canadian researchersfound that not only does pasta not cause weight gain,but three meals a weekcan help people drop more than half a kilogram over four months.Thereviewers found that pasta had been unfairly

minds of many inventors,some developing cycle-powered craft,others 26 money into jetpacks(飞行背包).However,.the flying car has always remained the27 symbol ofpersonal transport freedom.Several companies around the world have produced 28 that can drive onroads and fly.Airbus has a futuristic modular(组件式的)concept involving apassenger capsule that can be29 from the road-going chassis(andpicked up by a helicopter-type machine.But all these concepts are massively expensive,require safety certificationstandards for road and air,need 30 controls,involve complex folding wingsand propellers,and have to be flown from air-strips.So they are likely to remainrich peoples playthings rather than practical transport solutions for the masses.A car that takes off from some London street and lands in another 31 streetis unlikely to happen,says Prof.Gray,a leading aeronautical engineer.Skytaxis are much more likely.But that wont stop inventors from dreaming upnew ways to fly and trying to persuade investors to back their sometimes 32schemes.Civilian aviation is being disrupted,not by the age-old desires for speed,romanticism and历少尖老研33,but by the pressing need to respond to a changing climate.New electricengines coupled with artificial intelligence and 34 systems will contribute toa more efficient,integrated transport system that is less polluting and less noisy.That may sound simple,but as Prof.Gray says,When I travel somewhere I likethis notion that when I finish my journey I feel better than when I started it.Thats completely at 35 with how I feel today.Now that would be

craziest headline Ive ever written,Ive reported that26 in livestock protection are happening with scientists painting eyes on thebutts of cows.The experiment is based upon the idea that farmers whoreprotecting their herd from lions would shoot and kill lions in an effort to protecttheir livestock.While this makes a lot of sense,it results in many lion deathsthat 27 would have been unnecessary.Researchers in Australia have been28 and testing a method of trickery to make lions think they are being watchedby the painted eyes on cow butts.This idea is based on the principle that lions and other 29 are far lesslikely to attack when they feel they are being watched.As conservation areasbecome smaller,lions are increasingly coming into contact with humanpopulations,which are expanding to the 30 of these protected areas.Efforts like painting eyes on cow butts may seem crazy at first,but they couldmake actual headway in the fight for conservation.If the method works,itcould provide farmers in Botswana-and 31-with a low-cost,sustainable tool to protect their livestock,and a way to keep lions safe frombeing killed.”oLions are 32 ambush()hunters,so when they feel their prey has 33them,they usually give up on the hunt.Researchers are 34 testing their ideaon a select herd of cattle.They have painted half of the cows with eyes and left微the other half as normal.Through satellite tracking of both the herd and thelions in the area,they will be able to 35 if their psychological trickery willwork to help keep farmers from shooting

Internet during class doesnt just steal focus from the educator,italso hurts students who are already struggling to 26the material.A newstudy from Michigan State University,though,argues that all students-including high achievers-see a decline in performance when they browsethe Internet during class for non-academic purpose.To measure the effects of Internet-based distractions during class,researchers 27 500 students taking an introductory psychology class at
