Two People, Two Paths

You must be familiar with the situation:Dad's driving,Mum's telling him where to go.
He's sure that they need to turn left.But she says it's not for another two blocks.Who has
the better sense of direction?Men or women.
They both do,a new study says,but in different ways.
Men and women,Canadian researchers have found,have different methods of finding
their way.Men look quickly at landmarks（地标）and head off in what they think is the right
direction.Women,however,try to picture the whole route in detail and then follow the path
in their head.
" Women tend to be more detailed,"said Edward Cornell,who led the study,"while
men tend to be a little bit faster and...a little bit more intuitive(直觉感知的）."
In fact,said Cornell,"sense of direction"isn't one skill but two.
The first is the"survey method".This is when you see an area from above,such as a
printed map.You can see,for example,where the hospital is,where the church is and
that the supermarket is on its right.
The second skill is the"route method".This is when you use a series of directions.
You start from the hospital,then turn left,turn right,go uphill一and then you see the
supermarket.
Men are more likely to use the survey method while women are more likely to use one
route and follow directions.
Both work,and neither is better.
Some scientists insist that these different skills have a long history.They argue it is
because of the difference in traditional roles.
In ancient times,young men often went far away with the older men to fish or hunt.
The trip took hours or days and covered unfamiliar places.The only way to know where you
were was to use the survey method to remember landmarks一the mountains,the lakes and
so on.
The women , on the other hand , took young girls out to find fruits and plants.These
activities were much closer to home but required learning well-used paths.So , women's
sense of space was based on learning certain routes. Women developed a sense of space out of the need
A.Ato go fishing.
B.to go hunting.
C.to learn well-used paths.
D.to go swimming.

A Sunshade（遮阳伞）for the Planet

Even with the best will in the world,reducing our carbon emissions is not going to prevent global warming. It has become clear that even if we take the most strong measures to control emissions, the uncertainties in our climate models still leave open the possibility of extreme warming and rises in sea level. At the same time,resistance by governments and special interest groups makes it quite possible that the actions suggested by climate scientists might not be implemented soon enough.
Fortunately,if the worst comes to the worst,scientists still have a few tricks up their sleeves. For the most part they have strongly resisted discussing these options for fear of inviting a sense of complacency that might thwart efforts to tackle the root of the problem. Until now,that is a growing number of researchers are taking a fresh look at large-scale"geoengineering"projects that might be used to counteract global warming."I use the analogy of methadone,"says Stephen Schneider,a climate researcher at Stanford University in California who was among the first to draw attention to global warming."If you have a heroin addict,the correct treatment is hospitalization,and a long rehab. But if they absolutely refuse,methadone is better than heroin."
Basically the idea is to apply"sunscreen"to the whole planet. One astronomer has come up with a radical plan to cool Earth:launch trillions of feather-light discs into space,where they would form a vast cloud that would block the sun's rays.It's controversial,but recent studies suggest there are ways to deflect just enough of the sunlight reaching the Earth's surface to counteract the warming produced by the greenhouse effect. Global climate models show that blocking just 1.8 percent of the incident energy in the sun's rays would cancel out the warming effects produced by a doubling of greenhouse gases in the atmosphere.That could be crucial,because even the most severe emissions control measures being proposed would leave us with a doubling of carbon dioxide by the end of this century,and that would last for at least a century more. What is NOT true of the effectiveness of"sunscreen",according to the last paragraph?
A.It deflects sunlight reaching the Earth to counteract the warming.
B.It blocks the incident energy in the sun's rays.
C.It is a controversial method.
D.It decreases greenhouse gases in the atmosphere.
