found in the African rain forest suddenly turns up in children in the American Midwest. It"s hard not to wonder
of the disease that comes from foreign animals is homing in on human beings. "Most of the infections (感染)
we think of as human infections started in other animals." says Stephen Morse, director of the Center for Public
Health Preparedness at Columbia University.
It"s not just that we"re going to where the animals are; we"re also bringing them closer to us. Popular foreign
pets have brought a whole new disease to this country. A strange illness killed Isaksen"s pets and she now thinks
that keeping foreign pets is a bad idea. "I don"t think it"s fair to have them as pets when we have such a limited
knowledge of them." says Isaksen.
"Laws allowing these animals to be brought in from deep forest areas without stricter control need changing."
says Peter Schantz. Monkey-pox may be the wake-up call. Researchers believe infected animals may infect their
owners. We know very little about these new diseases. A new bug (病毒) may be kind at first. But it may
develop into something harmful (有害的). Monkey-pox doesn"t look a major infectious disease. But it is not
impossible to pass the disease from person to person.

There"s more bad news for vitamins this week: Turns out that taking folic acid (叶酸) and vitamin B12
supplements doesn"t prevent heart attacks or death, according to a major new study in the Journal of the
American Medical Association. It was hoped they would, since the vitamins do reduce levels of homocysteine (高半胱氨酸), an amino acid (氨基酸) that is higher in the blood of people who have a higher risk of heart
disease. In fact, homocysteine was reduced 30 percent after one year of treatment in the participants who
took both vitamins. But in the following three years, just as many vitamin takers died as those who didn"t take
the vitamins. Even worse, the study was stopped early because another similar study suggested that there may
be an increased risk of cancer from taking B vitamins.
I had been taking a health-food store monster multivitamin (综合维生素剂) for months. Coincidentally, I
had been experiencing some strange numbness in my legs that was starting to scare me. I remember sitting in
a long meeting with my ankles crossed, and when I tried to stand up I crumpled on the floor and hit my chin
on the glass coffee table because my leg had gone completely numb and worthless. As I sat there and shook
my leg, I got that"pins and needles" feeling and soon was OK. But it scared me enough to make an appointment with a neurologist, who suggested an MRI to rule out stroke, or a brain tumor(肿).
While I"ll never know for sure if the vitamins caused my problem, many, many studies have reminded us
that pill forms of vitamins and minerals don"t provide the same benefit as getting them from food. There"s a lot
we don"t know about how the human body works. Until we know more, I"m getting most of my vitamins from
the farmer"s market.
B. The writer continues to take vitamins in great quantities.
C. The writer is getting vitamins from food, which can provide more benefits.
D. The writer will never take pill forms of vitamins and minerals.
B. They want to live longer.
C. They want to increase risk of cancer.
D. They want to experience some strange numbness.
B. Taking more vitamins will not make a man healthier or live longer.
C. The vitamins can reduce levels of homocysteine in our body.
D. The less homocysteine in our blood, the less chance we"ll have heart attacks.
B. Vitamins: No Help for Your Heart
C. Vitamins: Bad for the Brain, Too
D. Some Bad News About Vitamins.
In the US and Britain, the slogan around colleges was "Save water. Shower with a friend." Now, Wuhan
University has come up with another system for the campus bathhouse. It charges students for the amount
of time in a shower. Before entering the bathhouse, students pay for the amount of time they want in the
shower with cash or their student ID card. The clock starts ticking the minute the tape is turned on. It pauses
when a button is pressed for soap. An integrated circuit (IC) card reader at each tap shows the time. No
money, no water. The benefits of the new system can be seen with the old system, which charged Yuan for
each person regardless of time in the shower. The university used about 320 tons of water daily under the old
system, but only 60 tons now.
Many students use the new system but opinions on it are divided. Some students say it is bad because
bathing had become a sort of race. Many people using it for the first time are not sure how long they need to
shower. Some might be embarrassed if their time is up and they"re still covered in soap. They have to ask the
bathhouse worker to help them buy extra time.
"It"s a flaw in the system that you can not buy extra time on the ID card," said Ren, a freshman in Wuhan
University. The university is also considering some students" suggestions that they be allowed to pay after
they"ve finished the shower. Not surprisingly, some are complaining about losing the hour shower. But many
students say the move helps them develop a water-saving sense.
Without the time limits, most students tended to shower for 30 to an hour in the bathhouse.
Some even used the hot water to wash their clothes."In my experience, 0-20 minutes is enough," said Dai
Zhihua, a third-year student who usually takes 8 minutes.
A similar system has been installed in other universities. Shanghai Normal University introduced it at its
Fengxiang Campus in September. The bathing fee there is 0.2 Yuan per minute. One male student responded
by setting a record with a two-minute shower.
B. The clock times all through while the student is bathing except when the bather paused for soap.
C. If money runs out, there will be no water.
D. Having finished bathing, the student has to pay for it.
B. advantage
C. pity
D. perfection
B. one third
C. one half
D. two thirds
B. the new operation can solve the water crisis.
C. a similar operation has been set in other universities.
D. The university has saved a lot of water by using the new system.
B. Society.
C. Campus Life.
D. Lifestyle.

pack a breakfast brown-bag the night before so that you and your kids can eat on the way to school and
work.
