In one of the strongest indications of the power of the mind to influence the body, a growing
collection of evidence finds that people who are depressed have a greatly higher risk of developing
heart disease.
     In a study of almost 3,000 men and 5,000 women, depressed men were 70 per cent more likely
to develop coronary (心脏的) heart disease than those who weren't depressed. While depressed
women were just 12 per cent more likely to develop heart disease, those who were severely depressed
were 78 per cent more likely. In fact, a 1998 study found that women who are depressed have a risk
of dying from heart disease equal to that of women who smoke or who have high blood pressure.
     The link works the other way around, too: While about 1 in 20 American adults experience major
depression in a given year, that number jumps to about one in three among those who have survived a
heart attack.
     The more severe the depression, the more dangerous it is to your health. But some studies suggest
that even mild depression, including feelings of hopelessness experienced over many years, may damage
the heart. Other studies suggest depression may affect how well heart disease medications work.
     Researchers aren't sure what the connection between depression and heart disease is, but theories
exist. One is that people who are depressed tend not to take very good care of themselves. They're
more likely to eat high-fat, high-calorie "comfort" foods, less likely to exercise, and more likely to
smoke. But beyond lifestyle, there is probably also a physiological link between depression and heart
disease. Recent studies found that people with severe, depression tended to have a lack of heart-healthy 0-3 fatty acids. People who are depressed also often have high levels of stress hormones (荷尔蒙).
These keep the body primed for fight or flight, raising blood pressure and causing the heart to beat faster,
all of which put additional stress on coronary arteries (动脉) and prevent the body's natural healing
mechanisms from working properly.
    A whole branch of medicine is devoted to the complex links between mental health, the nervous
system, the hormone system and so on. This science is gradually sorting out how the mind-body
connection affects us, or defenses against heart disease.
Generally, an estimated 10 per cent of American adults experience some form of depression every year.
Although available treatments can ease symptoms (症状) in more than 80 per cent of people treated, less
than half of those with depression get the help they need.

     Why did the chicken cross the road? To get to the other side.
     Most people know this joke. But recently, some people have been much more worried about how
the grizzly bear (灰熊) and mountain lion can cross the road.
     "Millions of animals die each year on U.S. roads," the Federal Highway Administration reports. In
fact, only about 80 ocelots, an endangered wild cat, exist in the U.S. today. The main reason? Roadkill.
     "Ecopassages " may help animals cross the road without being hit by cars. They are paths both over
and under roads. "These ecopassages can be extremely useful, so that wildlife can avoid road accidents,"
said Jodi Hilty of the Wildlife Protection Society.But do animals actually use the ecopassages? The
answer is yes. Paul Beier of Northern Arizona University found foot marks left by mountain lions on an
ecopassage that went under a highway. This showed that the lions used the passage.
     Builders of ecopassages try to make them look like a natural part of an area by planting trees on and
around them. Animals seem to be catching on. Animals as different as salamanders (火蜥蜴) and grizzly
bears are using the bridges and underpasses.
     The next time you visit a park or drive through an area with a lot of wildlife, look around. You might
see an animal overpass!

1. The writer uses the example of "ocelots" to show that _______.

A. wild animals have become more dangerous
B. the driving conditions have improved greatly
C. the measure for protecting wildlife fails to work
D. an increasing number of animals are killed in road accidents

2. From the news story, we know an ecopassage is ________.

A. an underground path for cars              
B. a fence built for the safety of the area
C. a bridge for animals to get over a river      
D. a path for animals to cross the road

3. When the writer says that animals seem "to be catching on", he means ________.

A. animals begin to realize the dangers on the road  
B. animals begin to learn to use ecopassages
C. animals are crossing the road in groups        
D. animals are increasing in number

4. The writer asks visitors and drivers to look around when traveling because ________.

A. wild animals may attack cars              
B. wild animals may block the road
C. they may see wild animals in the park      
D. they may see wild animals on ecopassages

    The weather is getting hotter. You are thirsty playing basketball or riding home from school. A cold drink
may be just the thing. But be careful what you are drinking. Something that looks cool may not be good for
your health. There are plenty of "energy drinks" on the market. Most of them have beautiful colors and cool
names. The lists on them tell you they are helpful to your health. Sounds great!
     But after a careful check you may find that most energy drinks have lots of caffeine (咖啡因) in them.
These drinks are especially aimed at young people, students, busy people and sports players. Makers
sometimes say their drinks make you better at sports and can keep you awake. But be careful not to drink
too much.
     Caffeine makes your heart beat fast. Because of this, the International Olympic Committee has limited (限
制) its use. Caffeine in most energy drinks is at least as strong as that in a cup of coffee or tea. Possible health
dangers have something to do with energy drinks. Just one box of energy drink can make you nervous, have
difficulty sleeping and can even cause heart problems. Scientists say that teenagers should be discouraged from
taking drinks with a lot of caffeine in them.

     There are different ways in which people try to deal with the problem of energy. One way is the greater production of common energy sources (能源), such as coal, oil and gas. The trouble with these sources,
however, is that they are not renewable (use again).
     Another way is energy conservation (节能), which means using energy more efficiently (有效地). In
some very cold countries people build special houses to save energy. They place materials between the
inside and the outside of the walls of the house to keep the cold out and the warmth in. The house is
heated by the lights, the body heat of the people and the other equipment in it.
     Finally, renewable energy sources are used even though they are often expensive to develop. One form of these is geothermal energy. In certain parts of the world the temperature of the earth increases thirty
degrees centigrade with each kilometer down. At six kilometres, therefore, it rises to nearly two hundred
degrees. To get the heat, water is pumped (压;抽) down into the rocks and back up to the surface. Heat
from the earth is already used in certain countries.

     Downing the last drop of an expensive famous brand H2O as weIl as remembering to
throw the empty bottle in the recycling bin.makes you feel pretty good about yourself, right?
It shouldn't. Even when the bottles are recycled, there are all kinds of otherconsequences of
swallowing bottled water, says Melissa Peffers, the air-quality program manager for
Environmental Defense.
    The containers are often filled in foraway lands, then shipped from abroad,and stored in
refrigerators at your local store. Compare that with the influence on environment of turning
on your tap ,filling a glass,and drinking up!
    Anyone who is choosing bottled water for health reasons ismisguided,says Peffers,"Most
bottled water is just tap water." And what comes out of your tap is carefully monitored to
follow the strictrules. Consider another fact that bottled water is surprisingly expensive.
especially when compared with the altemative,which is almost free ,andit is astonishing that
America's desire for bottled water seems impassibleto satisfy,reaching nearly 30 billion
bottles a year.
    "My parents' generation never  had  bottled water, "saysIsabelle Silverman,an
Environinental Defense legal adviser. She hasmade a commitment to going bottle free."You
don't need to fetch ithome from the store,and it's cheaper, " she adds
Bottled water's role as a status symbol needs to change,Pefferspoints out. So when a waiter
at an expensive restaurant offers"Andwhat's your drink?"that's no reason to forget your
conviction(信念). "Don't be afraid to say,'I'll have tap.' Say it loud enoughthat the other
tables nearby can hear you,"Peffers says,"And thenspend that money on a dessert. "
