In 2004, the World Health Organization, WHO, warned of a possible outbreak of another serious disease
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. |

If international leaders were as united as the scientific community on climate change, global warming might
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. |
| 1. The passage was written to tell us that _____. |
A. developed countries should cut their greenhouse gas emissions
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 |
2. This year"s talks will be the most important international environmental discussions in over a decade
because _____. |
A. no such summit will be held again before the end of 2012
B. people in the world have been faced with a global vacuum
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 |
| 3. The underlined word "holdout" in paragraph 4 probably means _____. |
A. one supporting to do something
B. one saying something may happen
C. one keeping on doing something
D. one keeping refusing to do something |
4. Which is the correct order,according to the events in the passage?
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. |
A. c-a-e-d-b
B. e-d-c-b-a
C. c-a-b-d-e
D. a-c-d-e-b |
| 5. What we can infer from the passage is that _____. |
A. the ex-prime minister of Australia was against the Kyoto Protocol
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 |

No one likes germs. You wash your hands often and avoid sick people. But some of the germiest places
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. |

C. a kind of cleaning tool
D. a kind of chemical liquid which can kill germs |
| 3. Which of the following statement is NOT true according to the passage? |
A. Some of the germiest places are outside your home.
B. Use a disinfectant to clean your bathtub weekly.

Fish contains lost of omega-3 fatty acids. These fatty acids have been shown to help prevent heart disease,
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. |

Australian scientists are trying to give kangaroo-style stomachs to cattle and sheep in order to cut the
greenhouse gases they send out, which is thought to be responsible for global warming.
Thanks to special bacteria in the stomachs, kangaroo flatulence (肠胃气胀) contains no methane (甲
烷) and scientists want to transfer that bacteria to cattle and sheep which produce large quantities of the
harmful gas.
While the usual image of greenhouse gas pollution is a huge smokestack pushing out carbon dioxide,
farm animals" passing wind contributes to a surprisingly high percentage of total emission (排放物) in
some countries.
"Fourteen percent of emissions from all sources in Australia is from methane from cattle and sheep,"
said Athol Klieve, a senior research scientist with the Queensland state government.
"And if you look at another country such as New Zealand, which has got a much higher agricultural
base,they are actually up around 50 percent," he said.
Researchers say the bacteria also make the digestive process much more efficient and could potentially
save millions of dollars in feed costs for farmers.
But it will take researchers at least three years to isolate the bacteria before they can even start to
develop a way of transferring it to cattle and sheep.
Another group of scientists,meanwhile,has suggested Australians should farm fewer cattle and sheep
and just eat more kangaroos. And about twenty percent of health-conscious Australians are believed to eat
the national symbol already.
"It"s low in fat, it"s got high protein levels and it"s very clean in the sense that basically it"s the free-range
(放养的) animal," said Peter Ampt of the University of New South Wales"s institute of environmental studies. |
| 1. The passage mainly talks about _____. |
A. a better way to prevent air pollution
B. the danger of methane from farm animals
C. possible solutions to protecting environment
D. a recent research on global warming |
| 2. Scientists intend to put the bacteria into cattle and sheep in order to _____. |
A. prevent them from sending out harmful gases
B. promote Australian farming
C. protect Australian ecosystem
D. make the most of the special bacteria |
| 3. Another possible solution to the problem is _____. |
A. to reduce the number of animals raised on farms
B. to keep more kangaroos rather than sheep and cattle
C. to eat more plants rather than beef and mutton
D. to grow more trees to absorb carbon dioxide |
| 4. From the passage we learn that _____. |
A. it is easy to transfer the bacteria to cattle and sheep
B. farm animals are to blame for global warming in some countries
C. cattle and sheep produce more methane than kangaroos
D. one fifth of Australians already eat their national symbol |

Emily and Madison were having a great time on their field trip. After a morning at the science museum
they went to their favorite fast food place. Emily got her food first. When Madison sat down next to her,
Emily couldn"t believe her eyes. Madison had two hamburgers, three containers of French fries, an apple
pie, a soda, and a shake on her tray.
"Why do you have so much food?" Emily asked. "I"m so tired of being really skinny (极瘦的)," Madison
said,"so I"ve decided to eat lots of food and try to gain weight."
Trying to gain weight by stuffing (塞, 填) yourself with extra calories like Madison did is a bad idea. It
can make you sick if you"re naturally short or thin- so just listen to your appetite (胃口) and eat only as
much as your body tells you to. Once in a while, a health problem can keep a kid from gaining weight. The
kid usually goes to a specialist who can check things out, or to a registered dietitian (饮食学家) who has
lots of tips on how to eat well. But most of the time, thin kids don"t need to see a doctor or go on a special
diet.
Here"s another surprise. Kids who are thin need to exercise. A lot of people use exercise to keep their
weight under control or to lose weight. But exercise serves many other purposes, too. Moving around helps
you develop important skills and helps your body get stronger. And unless a kid has gone through puberty
(青春期), weight-lifting won"t build bigger muscles. It also could hurt bones, joints, and muscles.
You want to help your body, not hurt it. Treat it right and you"ll grow and develop just the way you
should. |
| 1. The opening part of this passage about Emily and Madison is used to _____. |
A. tell us that Emily was not pleased with Madison
B. introduce the topic of gaining weight
C. suggest that Emily and Madison often went to their field trip
D. tell us that Emily and Madison were close friends |
| 2. If you are short and thin as you should you"d better _____. |
A. eat as much as you want to every day
B. see a doctor as soon as possible
C. force yourself to eat more every day
D. eat as much as you can to gain weight |
| 3. Which one of the following is TRUE according to this passage? |
A. Only fat people need to exercise to lose weight.
B. Madison should have much food because she was thin.
C. Thin people also need to exercise.
D. You must be ill if you are too thin or too short. |
| 4. What would be the best title for the passage? |
A. The thinner You Are the More You Should Eat.
B. Emily and Madison - Two Close Friends.
C. The Thinner You Are the Better You Will Be.
D. What Should You Do if You Are Thin? |
