Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is
another factor that can cause your heart problems more immediately: the air you breathe.
Previous studies have linked high exposure (暴露)to environmental pollution to an increased risk of heart problem,
but two analyses now show that poor air quality can lead to heart attack or stroke (中风)within as little as a few hours
after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物)were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate
study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of "moderate" (良好)quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14
hours of exposure.
The authors of both studies stress that these risks are relatively small for healthy people and certainly modest
compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware
of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation
by the EPA of pollutants may not only improve environmental air quality but could also become necessary to
protect public health.

tiger cubs-one-year-old Hope and Cathay and six-month-old Tiger Woods and Madonna are learning to
hunt in the wild. The hope is that they will one day pass on their skills to their young, allowing the next
generation to get back to wildlife reserves (保护区) in China.
A survey shows that the tigers are in more danger of dying out than China"s most famous animal,the
giant panda. Forty years ago, about 4,000 South China tigers lived in the wild. Today there are only
about 30. An additional 64 live in 19 zoos in China,which are all descendants(后代) of six wild animals
seized in 1956.
The cubs were born in zoos in China and removed from their mothers when they were three months
old. Their first home in South Africa was a one-acre camp where they stayed for a month. Their next
home was a ten-acre area,where they lived for three months to help them gradually get used to life
outside a cage.
When the cubs first arrived in South Africa,they didn"t even want to leave their cages. It took weeks
to get them to eat chicken, used as they were to being fed beef at the zoo in China where they were born.
It took months of practice to hunt a live animal and then make the link between the kill and food. Now
just a few months on, and living in a 150-acre camp,they have become remarkably skilled hunters.
All four animals will finally return to zoos in China while the pioneering pairs" cubs will grow up
completely wild. The aim is for the first rehabilitated tigers to go to reserves developed in China by 2008 ,when the Olympic Games will be held in Beijing.

market began. He"s been extremely important to the development of the emissions-trading (排污权交易
)industry since its beginnings. As chief economist for the Chicago Board of Trade in the 1970s, he had
helped develop the financial futures (期货) market, and in the late 1980s and early 1990s he all but
invented cap-and-trade programs for sulfur dioxide (SO?) emissions, the pollutant that causes acid rain.
The methodology was simple: the government puts a cap, or an upper limit on SO? emissions and then
the market takes over, with companies that can economically reduce SO? on their own allowed to sell
emissions fights to those that can"t. Doing the same thing with greenhouse emissions was the logical next
step, and from the 1992 Earth Summit on, Sandor was at the forefront of those efforts, launching the
Chicago and the European Climate Exchanges, where companies could meet to trade carbon.
Sandor is a creator and a great promoter of new markets, and he has the vision, to create something
out of nothing. He doesn"t just work at the level of theory, but encourages others to get involved. And
he"s always been good at making money. He realized that if we built enthusiasm in a market for actually
valuing the reduction of carbon emissions-and the global carbon market is already worth more than
$30 billion-we"d remember for decades to come as a true pioneer-a man who used the power of
financial incentives (激励)as a force for change.
B. in order of importance
C. by time
D. by comparison
B. The market.
C. Companies that can reduce SO? emission.
D. Companies that can"t reduce SO? emission.
B. always works in a way that is not practical
C. is a man of imagination rather than action
D. is strongly against developing industry
B. sympathy
C. doubt
D. regret
What you need is to change your eating habits forever. You begin by keeping a complete record of
what, where, when and how you eat. Once you understand your bad eating habits, you will find it easier
to exchange them for good ones. So keep a diary answering the following questions:
What do I eat during a day? Record every bit of food and drink you put in your mouth. This includes
that cracker you ate while opening the can ofsoup. It includes that Coca Cola you sipped from your
friend"s glass. It includes your chewing gum. And remember when you stuck your finger I the peanut
butter jar. Remember everything! Most people are astonished at what they eat and drink in one day.
Behavior Change: Make a list of what you plan to eat during the day and follow your plan.
Where and when you eat? Do you eat standing or lying? Do you eat while cooking, reading watching
TV or driving? Do you eat when upset, angry, worried, or hurried? Do you reward or punish yourself
with food? Behavior Change: Eat three planned meals only. Sit up straight at your table. Do nothing but
eat.
How do I eat ? Most of us eat on the run. When we eat fast , our stomachs don"t get the message
that we are full. So we keep eating. Behavior Change: look at your food . Give yourself a chance to resist
its sight and small. Chew slowly. Cut up your food into small pieces and eat one piece at a time. Let your
