Does that mean the more the better? The data from 16 studies were analyzed, 1 more than 833,234 adults.
14、The span of the studies 2 from 5 to 26 years. 56,423 adults participating in the studies died. Overall, the more fruits and vegetables people 3 , the less likely they were to have died during the study period. For every 4 serving eaten, up to four a day, the chance of dying for any reason decreased
15、by 5 percent. Those who ate four servings a day were 24 percent less 5 to have died than those who ate none at all. However, eating five or more daily servings indicated no added 6 . Higher consumption of fruits and vegetables also showed 7 no effect on the probability of dying from cancer. Although
16、 the recommendation of the 8 serving varies with age, health status and other factors, most adults are called for to fill half their plate with fruits and vegetables. The food pyramid(金字塔)model 9 that adults eat three to five servings of vegetables and two to four servings of fruits daily. However,

19、 as is, say, belief in democracy or aversion to nylon. But now that everyone has claims to love Mother Earth, how are we to choose among the dozens of conflicting proposals, restrictions, projects, regulations and laws advanced in the name of the environment? Clearly not everything with an environme
20、ntal claim is worth doing. How to choose?B)There is a simple way. First, distinguish between environmental luxuries and environmental necessities. Luxuries are those things that would be nice to have if costless. Necessities are those things we must have regardless. Then apply a rule. Call it the fu
21、ndamental principle of sensible environmentalism: Combating ecological change that directly threatens the health and safety of people is an environmental necessity. All else is luxury. For example: preserving the atmosphere, by both protecting the ozone layer and halting the greenhouse effect, is an
22、 environmental necessity. In April scientists reported that ozone damage is far worse than previously thought. Ozone reduction not only causes skin cancer and eye cataracts(白内障), it also destroys plankton(浮游生物), the beginning of the food chain on top which we humans sit.C)The reality of the greenhou
23、se effect is more speculative, though its possible consequences are far deadlier: melting ice caps, flooded coastlines, disturbed climate, dried up plains and, ultimately, empty breadbaskets. The American Midwest feeds the world. Are we prepared to see Iowa acquire Albuquerques climate? And Siberia
24、acquire Iowas? Ozone reduction and the greenhouse effect are human disasters. They happen to occur in the environment. But they are urgent because they directly threaten man. A sensible environmentalism, the only kind of environmentalism that will win universal public support, begins by unashamedly
25、declaring that nature is here to serve man. A sensible environmentalism is entirely man-centered: it calls for man to preserve nature, but on the grounds of self-preservation.A Sensible Environmentalism Does Not Sentimentalize the EarthD)A sensible environmentalism does not sentimentalize the earth.
26、 It does not ask people to sacrifice in the name of other creatures. After all, it is hard enough to ask people to sacrifice in the name of other humans.(Think of the public resistance to foreign aid and welfare.)Ask hardworking voters to sacrifice in the name of snail darter(蜗牛鱼), and, if they are
27、feeling polite, they will give you a shrug.E)Of course, this man-centeredness runs against the grain of a contemporary environmentalism that worships the earth to the point of excess. One scientific theoryGaia theoryactually claims that Earth is a living organism. This kind of environmentalism likes
28、 to consider itself spiritual. It is nothing more than sentimental. It takes, for example, a highly selective view of the kindliness of nature. My nature worship stops with the May storms that killed more than 125,000 Bengalis and left 10 million homeless.F)A non-sentimental environmentalism is one
29、founded on Protagoras principle that “ Man is the measure of all things“. Such a principle helps us to fight our way through the jungle of environmental argument. Take the current debate raging over oil drilling in a corner of the Alaska National Wildlife Refuge. Environmentalists, fighting against
30、a bill working its way through Congress to permit such exploration, argue that we should be conserving energy instead of drilling for it. This is a false either/or proposition. The country does need a substantial energy tax to reduce consumption. But it needs more production, too. Government estimat
31、es indicate a nearly fifty-fifty chance that under the ANWR lies one of the five largest oil fields ever discovered in America.G)We have just come through a war fought in part over oil: Energy dependence costs Americans not just dollars but lives. It is a ridiculous sentimentalism that would deny ou
32、rselves oil that is peacefully attainable because it risks disrupting the breeding grounds of Arctic reindeer(驯鹿). I like the reindeer as much as the next man. And I would be rather sorry if their mating patterns are disturbed. But you cannot have everything. And if the choice is between the welfare
33、 of reindeer and reducing oil dependence that gets people killed in wars, I choose man over reindeer every time.H)Similarly the spotted owl. I am no enemy of the owl. If it could be preserved at no or little cost, I would agree: the variety of nature is a good, a high aesthetic(美学的)good. But it is n
34、o more than that. And sometimes aesthetic goods have to be sacrificed to the more fundamental ones. If the cost of preserving the spotted owl is the loss of livelihood for 30,000 logging families, I choose family over owl. Man Is the Master of NatureI)The important distinction is between those envir
35、onmental goods that are fundamental and those that are merely aesthetic. Nature is our charge. It is not our master. It is to be respected and even cultivated. But it is mans world. And when man has to choose between his well-being and that of nature, nature will have to accommodate.J)Man should acc
36、ommodate only when his fate and that of nature are bound up together. The most urgent accommodation must be made when the very integrity of mans environmente. g. : atmospheric ozone is threatened. When the threat to man is of a lesser order(say, the pollutants form coal- and oil-fired generators tha
37、t cause death from disease but not fatal damage to the ecosystem), a more moderate accommodation that balances economic against health concerns is in order. But in either case the principle is the same: protect the environmentbecause it is mans environment. The sentimental environmentalists will cal
38、l this saving nature with a totally wrong frame of mind. Exactly. A sensiblea humanisticenvironmentalism does it not for natures sake but for our own.（分数：20.00）(1).The fundamental principle of sensible environmentalism is to battle against ecological change which threatens peoples health and safety.
39、（分数：2.00）填空项 1:_(2).Only when the very integrity of mans environment is threatened, will they make the most urgent accommodation.（分数：2.00）填空项 1:_(3).It is necessary to protect the ozone layer because ozone reduction damages the beginning of the food chain.（分数：2.00）填空项 1:_(4).According to the author,
40、 it is difficult to ask men to make personal sacrifice for others sake.（分数：2.00）填空项 1:_(5).The key point of the sensible environmentalism is that man is the master of nature.（分数：2.00）填空项 1:_(6).As opposed to a sensible environmentalism, a particular contemporary environmentalism claims that Earth is
41、 a living organism.（分数：2.00）填空项 1:_(7).Just like a democratic belief, environmental sensitivity nowadays is considered as a required attitude in the upper class.（分数：2.00）填空项 1:_(8).Those believing that energy should be conserved instead of being drilled are wrong because both energy tax and producti

43、1:_11.Section C_Millions of teenagers are in danger of putting their health at risk by getting hooked on e-cigarettes, experts warn. Leading health researchers say they are “very concerned“ by the growing number of youngsters trying the devices as a major new study reveals one in five teenagers has
44、accessed them. E-cigarettes have been marketed as a healthier alternative to smoking conventional cigarettes. But previous research shows e-cigarettes generate poisonous chemicals similar to those found in tobacco and may harm the lungs and immune system. Worryingly, researchers at Liverpool John Mo
45、ores University discovered 16% of teenagers who have used e-cigarettes had never previously smoked. The experts also found e-cigarettes were “ strongly related“ to drinking among teenagers. Study author Prof. Mark Bellis warned that such “ rapid penetration into teenage culture of what is essentially a new drug-use option is without precedent(先例). “ He added: “ Our research suggests that we should be very concerned about teenagers accessing e-cigarettes. While debate on e-cigarettes has focused largely on whether or not they act as a
