7、al Park Service says to stay at least 25 yards from any buffalo(and 100 yards or more away from bears and wolves).Buffalo are particularly unpredictable and charge people at speeds up to 30 mph.You can take your bicycle on any public roads and routes designed for bikes,but bicycles are not allowed o

11、rouble.Do teenagers simply love taking all risks much more than adults?A recent study suggests otherwise.Scientists designed a simple experiment involving 33 teenagers and three other age groups.In the experiment,the researchers tried to distinguish between two very different kinds of risk-taking.Th

12、e first they called a willingness to take known risks(when the probability of winning is clear)and the second they called a willingness to take unknown risks(when the possibility of success is-3-uncertain).The study offered participants the opportunity to play two kinds of games.They had the chance

13、to win-4-money,with one game offering a known risk and the other offering an unknown risk.On each round of the game,each participant had to choose between taking a sure$5 and known or unknown risks of winning a lot more.If on one particular round they had picked the$5 for sure choice,then they got$5

14、.But if on that round they had chosen to take a risk,the rules of the game will determine whether or not they had won.If they did win,they went home with between$8 and$125.And,of course,if they lost,they went home with nothing.What the scientists found was really quite surprising.It turned out that

15、the average teenager was very hesitant when risks were known more careful than college students or parents-aged adults,and about as careful as grandparent-aged adults.This means that when the risks were known,teenagers were not risky in their behavior at all.Only when the risks were unclear did teen

16、agers choose them more often than other groups.Under those kinds of conditions,they were much more willing to take a risk than any other group.So,what does all of this mean?The research suggests that adults should probably focus more energy on trying to educate teenagers about risks than limiting th

17、em.Teenagers who understand the risks associated with a decision are more likely to be careful in their behavior.4.This experiment was carried out by A.dividing the teens into three groups B.comparing the reactions to different risks C.giving equal amount of awards to the participants D.observing th

20、orning as they walked deep into the rainforest in the Maliau Basin in Borneo,where they had set up a set of experiments to look at the ecological effects of small creatures:termites（白蚁）.-5-Termites get a bum rap.They make headlines for chewing up billions of dollars of property each year in the U.S.

21、And they are responsible for something like two percent of global carbon emissions,simply as a result of their huge populations and preference for chewing through carbonrich materials.A whole industry is aiming at killing them.But they play a key role in many natural ecosystems.Scientists have known

22、 for years that in tropical（热带的）forests,termites chew up fallen leaves and dead wood,keeping the fallen material under control and letting nutrients from the dead material back into the system to be used by other plants,insects,and animals.But they didn t know exactly howanm poe insects were in keep

23、ing the forest healthy and functional,so they removed termites from a particular spot in the forest and saw how it responded.As luck would have it,Hannah Griffiths and her colleagues started their experiment when the forest was hit by an extreme drought（干旱）.During the non-drought years,they saw ther

24、e wasn t much difference between the normal plots and the ones where they d removed the termites.But during the drought,the effects were marked.What they found was unexpected:in the termite-rich areas,the soil stayed slightly wet,more tree seedlings sprouted（抽芽）,and the system was full of activity d

25、espite the long,hard dry spell.For Griffiths,it was only because they happened to study the drought that they could pick out the real importance of termi tes to the system,she points out.And that rings alarm bells in my head,“because it makes me think,well what else don t we know?If we start damagin

29、think twice before damaging a species.D.We should study the drought to improve the system.D If humans pump enough carbon dioxide(CO 2)into the atmosphere,the stratocumulus clouds(层积云)could disappear,and the earths temperature could climb sharply to heights not predicted in current climate models.It

30、would burn the planet.Thats the conclusion of a paper published in the journal Nature Geoscience and described in detail by Natalie Wolchover for Quanta Magazine.As Wolchover explained,clouds have long been one of the great uncertainties of climate models.Computer models that easily capture the comp

31、lexity and detail of most climate systems just arent powerful enough to predict worldwide changes in cloud behavior.But clouds are important.They reflect sunlight away from the earths surface.And stratocumulus clouds are those white blankets you might have seen as you looked out the window of arm ai

32、rplane,rolling out below you and hiding the ground Researchers suspect that certain sudden,past jumps in temperature may have been caused by changes to clouds like these.For the new research,scientists modeled just a small patch of sky using a supercomputer.They found that if carbon dioxide levels r

33、each about 1,200 parts per million(ppm)in the atmosphere,stratocumulus clouds break up.Thats a very high carbon dioxide concentration.Right now,levels have climbed past 410 ppm-a dangerous change from 280 ppm before the Industrial Revolution.But humans put more and more CO 2 into the atmosphere ever

34、y year.If current trends continue,the earth could reach 1,200 ppm within 100 to 150 years.This could happen if our society doesnt follow through on any of its commitments to reduce emissions(排放),Wolchover reported.And even if it_does,the result would be another 8 degrees Celsius of heat added to the

35、 global average,on top of the dangerous changes already underway due to greenhouse gases.That s an enormous change,and it goes beyond prednons of worldwide ice melt and catastrophic sea level rise.And,once the stratocumulus clouds are gone,Wolchover reported,they likely wouldnt reappear until atmosp

36、heric carbon dioxide levels dropped below where they are currently.Theres still some uncertainty in the data.The 1,200 ppm figure could change as scientists look into the issue further.12.What can we learn from paragraph 2?-7-A.Most climate systems are not complex.B.Cloud behavior is uncertain and h
