Do friends of the opposite gender distract teenagers,hampering their academic performance?It may seem obvious,and yet it is hard to prove.A survey of American schoolchildren conducted in 1995,for example,suggests no link between the proportion of a girl's friends who were boys and her grades.A new paper by Andrew Hill of the University of South Carolina,however,comes to a different result.He finds that for every 10%more children of the opposite sex among a student's friends,his or her grade-point average（GPA）declines by O.l（GPAs range from O t0 4）.Not only may having more friends of the opposite sex be bad for grades,but it has other effects,too.Among the children from the original survey who were successfully re-interviewed 14 years later,those whose grades had been dragged down by friends of the opposite gender were more likely to be married.

Older Volcanic Eruptions
Volcanoes were more destructive in ancient history,not because they were bigger,but because the carbon dioxide they released wiped out life with greater ease.
Paul Wignall from the University of Leeds was investigating the link between volcanic eruptions and mass extinctions.Not all volcanic eruptions killed off large numbers of animals,but all the mass extinctions over the past 300 million years coincided with huge formations of volcanic rock.To his surprise,the older the massive volcanic eruptions were,the more damage they seemed to do.He calculated the"killing efficiency" for these volcanoes by comparing the proportion of life they killed off with the volume of lava（熔岩）that they produced.He found that size for size,older eruptions were at least 10 times as effective at wiping out life as their more recent rivals.
The Permian（二叠纪）extinction,for example,which happened 250 million years ago,is marked by floods of volcanic rock in Siberia that cover an area roughly the size of western Europe.Those volcanoes are thought to have pumped out about 10 gigatonnes of carbon as carbon dioxide.The global warming that followed wiped out 80 percent of all marine genera（种类）at the time,and it took 5 million years for the planet to recover.Yet 60 million years ago,there was another huge amount of volcanic activity and global warming but no mass extinction.Some animals did disappear but things returned to normal within ten thousand of years."The most recent ones hardly
have an effect at all,"Wignall says.He ignored the extinction which wiped out the dinosaurs 65 million years ago,because many scientists believe it was primarily caused by the impact of an asteroid（小行星）.He thinks that older volcanoes had more killing power because more recent life forms were better adapted to dealing with increased levels of CO₂．
Vincent Courtill.ot,director of the Paris Geophysical Institute in France,says that Wignall's idea is provocative.But he says it is incredibly hard to do these sorts of calculations.He points out that the killing power of volcanic eruptions depends on how long they lasted.And it is impossible to tell whether the huge blasts lasted for tliousands or millions of years.He also adds that it is difficult to estimate how much lava prehistoric volcanoes produced,and that lava volume may not necessarily correspond to carbon dioxide emissions。

What can be inferred from Paragraph 3 concerning dinosaurs?
A:They were killed off by an asteroid.
B:They died of drastic climate change.
C:They were wiped off by a volcanic eruption.
D:The cause of their extinction has remained a controversial issue.

1.All research to date on body image shows that women are much more critical of their appearance than men and much less likely to admire what they see in the mirror. Up to 8 out of 10 women are dissatisfied with their reflection,and more than half may see a distorted image.
2.Men looking in the mirror are more likely to be either pleased with what they see or indifferent. Research shows that men generally have a much more positive body-image than women一if anything,they may tend to over-estimate their attractiveness.Some men looking in the mirror may literally not see the flaws in their appearance.
3.Why are women too much more self-critical than men?Because women are judged on their appearance more than men,and standards of female beauty are considerably higher and more inflexible.Women are continually bombarded with images of the inflexible.Women are continually bombarded with images of the"ideal"face.And constant exposure to idealized images of female beauty on TV,magazines and billboards makes exceptional good looks seem normal and anything short of perfection seem abnormal and ugly.It has been estimated that young women now see more images of outstandingly beautiful women in one day than our mothers saw throughout their entire adolescence.
4.Also,most women are trying to achieve the impossible:standards of female beauty have in fact become progressively more unrealistic during the last century.In 1917,the physically perfect woman was about 5 feet 4 inches tall and weighed nearly 10 stone（约140磅）.Even 25 years ago, top models and beauty queens weighed only 8% less than the average woman,now they weigh 23% less.The current media ideal for women is achievable by less than 5% of the female population一and that's just in terms of weight and size.If you want the ideal shape,face,etc, it's probably more like 1%.

A:How do men view their appearance?
B:How can women make themselves more beautiful?
C:Why do men and women view their appearance differently?
D:Is it possible for women to meet the standards of perfect beauty?
