I"m a skeptic (怀疑论者) when it comes to the benefits of taking vitamins and other supplements. We
swallow far more than any other country- yet we"re not the healthiest folks by far, nor do we live the longest.
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. |

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. |
| 1. According to the passage, which of the following is NOT true? |
A. Students pay for the amount of time they want in the 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. |
| 2. The underline word "flaw" (Paragraph 3) most probably means ______. |
A. fault
B. advantage
C. pity
D. perfection |
| 3. Since the new system has performed, ______ of water can be saved. |
A. a quarter
B. one third
C. one half
D. two thirds |
| 4. It can be inferred from the passage that ______. |
A. The new operation can raise students" environmental awareness.
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. |
| 5. In which column can you find this passage? |
A. People.
B. Society.
C. Campus Life.
D. Lifestyle. |

(1)While adults need to eat breakfast each day to perform their best, kids need it even more. Their
growing bodies and developing brain rely heavily on the regular intake of food. When kids skip breakfast,
they can end up going for as long as eighteen hours without food. This period of semi-starvation can create
a lot of physical, intellectual, and behavioral problems for them.
(2)If you and your kids regularly skip breakfast to save time or to get a few more minutes of sleep,
remember that eating a healthy morning meal will probably save your time in the long run. By recharging
your brain and your body, you"ll be more efficient in just about everything you do.
(3)Interestingly, studies show that kids who skip breakfast are late for and absent from school more
often than children who eat breakfast on a regular basis. Time invested in breakfast is much more valuable
than the few extra minutes of sleep you might get by skipping the morning meal. If you and your kids seem
unable to make time for breakfast, consider enrolling your children in a school breakfast program. If possible,
pack a breakfast brown-bag the night before so that you and your kids can eat on the way to school and
work.
(4)Some people skip breakfast in an effort to lose weight, but actually it is more likely to cause weight
gain rather than weight loss. Skipping breakfast is strongly linked to the development of obesity. According
to research, skipping meals, especially breakfast, can actually make weight control ________. Breakfast
skippers tend to eat more food than usual at the next meal or eat high-calorie snacks to get rid of hunger.
(5)To teens, especially teenage girls, skipping breakfast may seem like a perfect way to lose weight.

As the population of the planet increases, so does the number of homes, businesses, parking lots, schools,
airports and roadways. All these structures use electricity and need to be lighted. Humans demand these lights.
They want their homes more comfortable and they want their streets sage. The problem is that researchers are
finding that all the light is having a negative effect on humans and wildlife as well.
Less than 10 years ago I drove to a thinly populated section of my town, lay down in the middle of the road
and watched an attracted meteor shower (流星雨). The area was short of homes, street lights and traffic. If I
did that today, I wouldn"t be able to see the meteor shower as well, and I would surely be run over by a car.
Nowadays scientists are finding light pollution can be almost as bad as carbon dioxide pollution. If you"ve
ever taken a flight at night, the view is beautiful, but you must remember that all the light you see is wasted
electricity. The crew of the space shuttles see an even bigger picture of how extensive the wasted electricity
is worldwide.
Additionally, electricity needs to be generated, and the generation of electricity creates pollution by giving
off greenhouse gases. This affects the air we breathe and our quality of life.
Scientists are also studying the effects of light pollution on wildlife. Thousands of birds die each year when
they crash into highly lighted buildings, as they become puzzled by the light. It has been long known that tiny
sea turtle hatchlings become lost and follow lights on the shore instead of heading towards the sea.
Fortunately, light pollution is one of the easiest sources of pollution that can be corrected without a negative
effect. Following some guidelines and a little searching on Google can give you many ideas on how to reduce
your contribution to light pollution. |
| 1. The author tells the story in the second paragraph mainly to _____. |
A. remember the past beauty of the town.
B. stress the advantages of less pollution
C. show the great changes of the town

| 2. In the passage the author advises people ______. |
A. to try to reduce unnecessary light.
B. not to ignore the beauty around.
C. to set proper light for animals
D. not to destroy the animal"s living conditions. |
| 3. What can be inferred from the passage? |
A. Light pollution is difficult to deal with.
B. Light pollution is a threat to some animals.
C. Light pollution has nothing to do with global warming
D. Astronauts can"t see clearly in space due to light pollution. |
| 4. What is most likely to be discussed in the paragraph which follows the last paragraph? |
A. The author"s contribution to light pollution
B. Other sources of light pollution
C. Ways of reducing light pollution
D. More bad effects of light pollution |

Celia was shocked. She had always been in good shape during high school, but now, in her first year
of college, she was suddenly ten pounds heavier. "My friends and I often had pizza or ice cream when
we studied late at night," she said, "and I was always drinking Coke to stay awake."
Celia"s experience is common. Many students enter college and find it so different that they cannot
deal with changes properly. They"re away from their parents and in a new stressful (压力的) environment.
Pressures (压力) together with freedom to sleep and eat however they please cause many students to
experience the "Freshman 15": gaining weight suddenly in their freshman year of college.
Most students do not realize that the "Freshman 15" can cause some serious health problems. Of
course, college-age adults are still developing bone mass,so gaining some weight is normal. Sudden weight
gain, however, puts too much strain (负担) on the heart and lungs,resulting in little energy and some
difficult thinking and remembering. In later life, it can lead to heart disease, diabetes, obesity, and possibly
cancer.
The solution to the"Freshman 15" is simple-pay attention to developing good habits! In general:
● Eat normal-sized meals at regular times. Eat slowly and enjoy it,so you don"t need to go back for more.
● Keep only healthy snacks in your room-and don"t snack too often!
● Control drinking and smoking. Alcohol has a lot of calories, and smoking too much makes exercise
difficult.
● Exercise regularly! Even just 30 minutes a day-such as walking quickly to class from your dorm-will
make a big difference! |
