index is within the "normal" range, according to a new study, over 350,000 people across Europe published
Wednesday in the US. magazine, New England Journal of Medicine.
The study provides strong evidence that storing excess (过量的) fat around the waist poses a significant
health risk, even in people not considered to be overweight obese (极肥胖的). It suggests that doctors should
measure a patient"s waistline and their hips as well as their body mass index as part of standard health cheeks,
according to the researchers from Imperial College London, the German Institute of Human Nutrition, and other
research institutions across Europe.
Comparing subjects with the same body mass index, the risk of premature death increased in a linear fashion
as the waist circumference increased. The risk of premature death was around double for subjects with a larger
waist (more than 120 cm for men and more then 100 cm for women) compared to subjects with a smaller waist
(less than 80cm for men and less than 65cm for women). Body mass index is commonly used to assess (评估)
if a person is of "normal" weight.
Each 5cm increase in waist circumference increased the mortality risk by 17 percent in men and 13 percent
in women, according to the study.
An increased risk of mortality (死亡率) may be particularly related to storing fat around the waistline because
fatty tissue in this areas secrete (分泌) cytokines (细胞因子), hormones (荷尔蒙) and metabolically (新陈代谢)
active compounds (混合物) that can contribute to the development of chronic (长期的) diseases, particularly
cardiovascular (心脏血管的) diseases and cancers, suggest the authors.
Tobias Pischon, the lead author of the paper, said "The most important result of our study is the finding that
not just being overweight, but also the distribution of body fat affects the risk of premature death of each
individual."
B. if he has a large waistline
C. if his body mass index is within normal range
D. if he overweight
B. hip
C. body mass index
D. waistline
B. Body mass index is commonly used to assess (评估) if a person is large waistline.
C. The smaller waistline, the more mortality risk.
D. Large waistline almost doubles risk of dying prematurely.

clearly. And, they help you look your best. Here are some tips for you to take care of your teeth.
1. Brush your teeth on the right way.
Brush your teeth at least twice a day-after breakfast and lunch or after sweet snacks, too. Brush all of your
teeth, not just the front ones, spend time brushing teeth along the sides and back of your mouth. Brush away
from your gums, too.
Spend at least three minutes each time you brush. Play a song you like to help pass the time. Get a new
toothbrush every three months. When you buy your toothbrush,be sure it has soft bristles (毛).
2. Learn how to floss your teeth.
Flossing is a very important way to keep your teeth healthy. Food may hide in places where a toothbrush
cannot get to, like the space between two teeth. Flossing can help get rid of it. Carefully move floss between
two teeth. Up and down. You"ll need to floss your teeth at least once a day.
3. Have good eating habits.
You need to be careful about what you eat and drink. Eating sugar is a major of tooth decay (腐败). Eating
sugar before you go to bed can make things even worse, eat lots of fruit and vegetables and drink water instead
of soda.

which may be even more deadly than SARS. The WHO believes that it is likely that bird flu will spread to
human beings in the next few years. If it does, up to seven millions people could die from the disease.
Diseases like bird flu are caused by viruses, that is, tiny things which change and become more dangerous
over time. When a new type of a common virus changes, it may be able to get past the body"s immune system.
If that happens, humans are in great danger until a cure or treatment becomes available.
There have always been viruses and people always get sick, of course, but as we saw with SARS, the
situation is more difficult today. People travel more than ever before, which means that disease can spread
quickly and across large areas-in fact the whole world.
Scientists are already working on drugs that will prevent or limit the effect of a new virus, but the process
takes time. It is just as important to make sure that countries, especially poor countries, are prepared to deal
with the disease. New disease usually affect poor areas the most, so we must help develop health care in all
countries.
B. people don"t eat health food
C. there aren"t enough hospitals
D. scientists can"t find a cure
B. a virus changes and become less dangerous over time
C. SARS is 1ikely to come again in some years
D. poor areas usually suffers more from Dew diseases than rich areas
B. Scientists Are Working Hard on Drugs for Diseases
C. What Is a Virus
D. Virus Changes and Causes New Diseases Over Time
be a thing of the past. "The world"s scientists have spoken clearly and with one voice," UN Secretary General
Ban Ki Moon said, "I expect the world"s policymakers to act the same."
Unfortunately, the global political community is a long way from speaking with one voice on anything, and
climate change is no exception. We"ll know for sure next week,when environment and energy ministers from
around the world meet on the Indonesian island of Bali for the UN"s climate change conference. The summit
(首脑会议) has been held nearly every year since 1992, when the UNFCCC (《联合国气候变化框架公约》)-
the document that has since guided international work on global warming-was agreed on. It was at the 1997
conference that the Kyoto Protocol was passed, but since then, there has been little progress.
This year"s talks will be the most important international environmental discussions in over a decade. The
Kyoto Protoco-which requires developed nations who have agreed on the solution to cut their greenhouse gas
emissions (排放) to about 5％ below their 1990 levels by 2012-comes to an end in just five years. The world
needs to begin immediately at Bali the process of preparing another document like Kyoto to be ready by the
end of 2012. Otherwise, we"ll be faced with a global vacuum (真空状态), just at the very moment when
greenhouse emissions must begin falling in order to avoid dangerous climate change.
The good news is that, just last week,150 top global corporations approved a request calling for necessary
cuts in greenhouse gas emissions, a business position that was unthinkable just a year ago. Australia-a Kyoto
holdout, like the U.S.-has just elected a new prime minister with a strong environmental record who says he"ll
support the protocol. The U.S. Congress and representatives have also stepped in and taken their own steps
on climate change.
"There is a building sense that enough time has been wasted and that it is time to act," said Jennifer
Haverkamp, international counsel for Environmental Defense.
B. international leaders should be united to work on climate change
C. greenhouse emissions are beginning to fall to avoid global warming
D. there has been little progress since the Kyoto Protocol was passed
because _____.

C. the solution in the Kyoto Protocol isn"t practical and it isn"t in effect now
D. a new document needs to be prepared before the Kyoto Protocol ends
B. one saying something may happen
C. one keeping on doing something
D. one keeping refusing to do something
a. The Kyoto Protocol was passed.
b. The Kyoto Protoco1 will come to an end.
c. The first summit was held and the UNFCCC was agreed on.
d. The UN"s climate change conference will be held on the island of Bali.
e. 150 top global corporations approved a request calling for cuts in greenhouse gas emissions.
B. e-d-c-b-a
C. c-a-b-d-e
D. a-c-d-e-b
B. leaders will soon unite in acting and no time will be wasted in talking
C. Ban Ki Moon expects the world"s policymakers to act like scientists
D. international leaders will speak clearly with one voice at the Bali summit
are in your own home where you can"t avoid them!
Over 77, 500 bacteria per square centimeter can live in your kitchen sink drain. More bacteria live in and
around the sink itself. To get rid of them, clean the entire sink area with a disinfectant.
Those wet clothes from your washer are not all that clean, especially if they include underwear. Use hot
water and bleach to wash underwear as it contains E.coli (大肠秆菌). Put wet laundry in the dryer quickly
so the bacteria do not multiply.
The germs you wash off your body stay in the tub-about 15.500 bacteria per square centimeter! Use a
disinfectant to clean your tub weekly. And dry the tub with a clean towel so more germs won"t grow on the
wet surface.
You"ll find plenty of germs outside your home too.
Lots of germs live on the buttons of your local ATM. According to www.health.corn, Chinese researchers
tested 38 ATMs in downtown Taipei. They found that each button hosted an average of 1,200 germs. Use a
hand sanitizer after using the ATM and after handling paper money too.
The bottoms of women"s purses house tens of thousands if not millions of bacteria. University of Arizona
researchers discovered all kinds of different bacteria on purse bottoms. These included E.coli as well as
bacteria that cause eye and skin infections. Women should wipe their purses every few days with a mild soap
solution.
All kinds of germs live on shopping cart shopping cart handles. Lots of people touch the handles each day-
and who knows where their hands have been! Carry disinfectant wipes and use them on the handles. That will
kill nearly all germs.
B. four
C. six
D. eight
B. a tablecloth
C. a kind of cleaning tool
D. a kind of chemical liquid which can kill germs

lower blood pressure and reduce the risk of strokes. Researchers suggest that these benefits of eating fish far
outweigh the risks of getting sick from contaminated fish.
Ongoing studies find that omega-3 fatty acids work magic on the brain too. Pregnant? Go out and eat fish!
One study tracked a group of expectant women who ate more than 340 grams of fish per week. It turns out
they gave birth to children who, years later, scored really high on IQ tests.
How can you add fish to your diet? One way to begin is by replacing meat with fish in one meal a week.
Instead of frying, which retains more fat, try boiling your fish in an oven or grilling it outdoors. And don"t be
afraid to spice up your fish. Garlic, herbs other spices can add wonderful flavors to fish.
For lighter meals, keep a few cans of tuna or other fish on hand at all times. They"re great for making tasty
sandwiches or fish burgers. If you get hungry in the middle of the morning or afternoon, try tuna on crackers.
It"s hard to find a better snack. And parents, be sure to introduce fish to your children. It"s important for them
to get used to eating it at a young age.
