{{B}}Obesity
Epidemic{{/B}}
Ask anyone why there is an obesity epidemic and
they will say that it’s all down to eating too much and burning too few
calories. That is undoubtedly true. But it’s also true that we live in an
"obesogenic (肥胖基因的) environment": calorific food is plentiful and cheap and our
lifestyles are increasingly sedentary.
Now, obesity researchers
are increasingly dissatisfied with such explanations. They believe that
something else must have changed in our environment to cause such dramatic rises
in obesity over the past 40 years or so. Nobody is saying that the "big two" --
reduced physical activity and increased availability of food -- are not
important contributors to the epidemic. But they cannot explain it
all.
Earlier this year a review paper by 20 obesity experts set
out the 9 most plausible alternative explanations for the epidemic. Here they
are.

[单项选择]To avoid the various foolish opinions to which mankind is liable, no superhuman genius is required. A few simple rules will keep you, not from all errors, but from silly errors.
If the matter is one that can be settled by observation, make the observation yourself. Aristotle could have avoided the mistake of thinking that women have fewer teeth than men, by the simple device of asking Mrs. Aristotle to keep her mouth open while he counted. He did not do so because he thought he knew. Thinking that you know when in fact you don’’t is a fatal mistake, to which we are all liable.
Many matters, however, are less easily brought to the test of experience. If, like most of mankind, you have strong convictions on many such matters, there are ways in which you can make yourself aware of your own prejudice. If an opinion contrary to your own makes you angry, that is a sign that you subconsciously are aware of having no good reason for thinking as you do. If someone maintains that two and t

The Exploding Lakes of Cameroon
What comes to mind when you think of a lake?You probably imagine a pretty scene with blue water, birds,and fish.For the people in the northwestern Cameroon,however,the image is very different.For them, lakes may mean terrible disasters.In 1984,poisonous gases exploded out of Lake Monoun and came down into the nearby villages,killing thirty-seven people.Two years later,Lake Nyos erupted.A cloud of gases rolled down the hills and into the valleys and killed 1,700 people.
Lake Nyos and Lake Monoun are crater（火山口）lakes.They were formed when water collected in the craters of old volcanoes.The volcanoes under Lake Nyos and Lake Monoun are not active anymore.However, poisonous gases from the center of the earth continue to flow up through cracks in the bottom of the lake.This is normal in a crater lake.In most crater lakes,these gases are released often because the water"turns over" regularly.That is,the water from the bottom of the lake rises and mixes with the water at the top,allowing the gases to escape slowly.
However,in Lakes Nyos and Monoun,there is no regular turning over.No one knows the reason for this fact,but as a result,these lakes have more gases trapped at the bottom than other crater lakes.In fact, scientists who have studied Lakes Nyos and Monoun have found 16,000 times more gases.When a strong wind,cool weather,a storm,or a landslide（滑坡）causes the water to turn over suddenly,the gases escape in a violent explosion.
In the past,no one knew when the gases might explode,so there was no way for the villagers to escape disaster.Now scientists from the United States,France,and Cameroon have found a way to reduce the gas pressure at the bottom of Lake Nyos.They stood a 672-foot plastic pipe in the middle of the lake,with one end of the pipe near the bottom and the other end in the air.Near the top of the pipe,the team put several holes that could be opened or closed by a computer.Now,when the gas pressure gets too high,the holes are opened and some of the gas-filled water shoots up through the pipe into the air like a fountain.With less pressure,a disastrous explosion is much less likely.However,the scientists are not sure that one pipe will be enough to prevent explosions.They hope to put in others soon and they plan to install a similar pipe and a computer system at Lake Monoun as well.
To protect people nearby until all of the pipes are in place,the scientists have installed early warning systems at both lakes.If the gas pressure rises to a dangerous level,computers will set off loud sirens（警 报）and bright lights to warn the people in the villages.In that way,they will have time to escape from the dangerous gases.
Lake Nyos and Lake Monoun explode because_____.
A.the gases rise to the top and mix with air
B.people from the villages turn over the water
C.scientists have put in a computer system
D.they have more gases trapped at the bottom than other crater lakes
