eat boxes of ice cream, bowls of noodles and plates of meat -- and all the while be losing
weight?
You might hate me, thinking 1 have one of those good metabolisms (新陈代谢) that just
burn up fat when it enters my body. You might wonder if I have an eating disorder. Or maybe
you"d just shrug your shoulders and figure I have a rich fantasy life. You"d be wrong.
For my body to perform such a surprising task, I would have to be a mouse. Not just any
mouse, but one lucky enough to be involved in a new study at Baylor College of Medicine in
Houston.
In the study, after discovering an enzyme (酶) that allows fat to be stored in the body,
scientists fed mice without those enzymes, and found those mice were able to eat far more
food than other mice and still weighed 10 to 15 percent less.
Best of all, the mice without the enzyme were in very good health, were able to produce
baby mice without any problem and generally acted like any other mouse. That"s great news
for researchers, who think that scientists may figure out a way to prevent the fat-metabolizing
enzyme in humans as a way to control weight gain. And such a pill would be very exciting for
many struggling to get rid of dangerous extra pounds.
But don"t start planning any big dinner just yet: At this point, of course, any pill for humans
is but a twinkle (闪烁) in the eye of every drug company"s CEO. More tests are to be conducted,
and eventually humans will be tested. But for now, unfortunately, controlling what you eat is still
the key to losing weight.
B. Burning fat very quickly.
C. Controlling your diet.
D. Having a rich fantasy life.
B. proved that there is a kind of enzyme which can cause weight gain
C. only included mice which didn"t have the fat - metabolizing enzyme
D. proved that all mice can control their weight easily
B. Scientists can"t find the key to discovering the enzyme.
C. The best way for people to lose weight now is still to control their diet.
D. Drug companies will make a lot of money in the future.
B. eating a healthy diet is a good way to prevent disease
C. the fat -metabolizing enzyme can improve metabolisms
D. the pills that help people control weight gain will be very popular if they are available

In the far north-eastern corner of South Africa, Kruger National Park is the largest
game reserve (野生动植物保护区) in the country, and the most famous wildlife zone
on the African continent. Stretching out over 7,332 square miles, Kruger is a wonderland
of wildlife. It has 507 species of birds and 147 species of mammals. It also has a fair bit
of history it dates back to 1898 when it was founded as a game reserve in an attempt to
control hunting in the area. It didn"t see a tourist until 1927; however, one year later it
became a national park.
It"s a good place to see roaring beasts in their own backyards. South Mrica is an
increasingly hot tourist spot, and you may want to visit it this year, before it hosts the
2010 football World Cup. South Africa is also an inexpensive country for tourists.
Anyone seeking to escape the European winter will be surprised to hear that March
is not the best time to go to Kruger.
The six-month period between May and October tends to be the most suitable time
for wildlife - spotting. The weather is not only cooler but also considerably drier. This
means that water sources dry up and animals are forced to approach rivers, creeks, dams
and watering holes in search of liquid refreshment.
If you go to South Africa, you need to pay attention to the threat of malaria (疟疾).
Kruger is one of the only two South African national parks that have an issue about the
disease, but only during the rainy season ( December to April).
A disadvantage of Kruger is that it sits a long way from South Africa"s other well-known
tourist attractions Cape Town, the Garden Route, and the meeting of the Atlantic and Indian
Oceans at Cape Agulhas.

encourage a 24-hour period free from all forms of tobacco consumption (消费) across the globe.
The day is further intended to draw global attention to the widespread prevalence of tobacco use
and to negative health effects, which currently lead to 5.4 million deaths worldwide annually (每年).
The member states of the World Health Organization (WHO) created World No Tobacco Day
(WNTD) in 1987. In the past twenty years, the day has been met with both enthusiasm and resistance
across the globe from governments, public health organizations, smokers, growers, and the tobacco
industry.
The WHO cites (提到)tobacco use as "one of the biggest public health threats the world has ever
faced." Tobacco is the number one preventable cause of disability and death. Tobacco can have many
negative health effects; it is a risk factor for six out of eight of the leading causes of death in the world,
Such as cardiovascular (心血管的) disease, lung diseases, and various cancers. The WHO blames 1
in 10 deaths worldwide on tobacco use, which equates to 5.4 million today. By 2030, they estimate
that the number of tobacco-related deaths will have risen to 8 million. Because of these issues, tobacco
consumption is seen by the WHO as a key public health issue.
WNTD is a part of the WHO"s larger strategy to change tobacco-related thinking and behaviors
around the world with the aim of making the world healthier. According to the WHO, the point of
World No Tobacco Day is to ask people to give up using all tobacco products for 24 hours in order to
begin breaking their addiction to the "harmful and wasteful habit." The day is meant to raise awareness
about the health risks associated with tobacco and advocate far better polices to reduce consumption
worldwide.

| 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. | |
| 1. Which of the following can be the best title of the passage? | |
| A. Depression -Heart Disease Risk Factor. B. Heart Disease -Health Killer. C. Depression - Mental Health Enemy. D. Heart Disease - Depression Factor. | |
| 2. Which statement is NOT true according to the passage? | |
| A. With high blood pressure, depression is another potential risk to women"s health. B. Depression, which is mild, can possibly cause damage to your health. C. Most people who experience depression get treated as they should be. D. Depression may have some influence on the function of heart disease medication. | |
| 3. According to the passage, the possible connections between heart disease and depression are the following EXCEPT ______ | |
| A. depressed ones tend to eat high-fat and high-calories foods, which leads to physical damage to heart B. severe heart disease may cause people to feel hopeless and depressed C. depression may result in the lack of some kind of acids, which probably affects the working of people"s heart D. people with depression often have a high level of stress hormones, maybe, which will put extra pressure on one s heart | |
| 4. We can infer from the passage that ______. | |
| A. more researches will be done to find the certain links between heart disease and depression B. the percentage of adults with depression is higher than that of depressed adults with heart disease C. one"s lifestyle has relatively little relationship with one"s mental health D. those with depression have a higher risk of developing heart disease | |

| 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 | |
