单选题Diabetes (糖尿病) and Eye Damage
Over 2 million Canadians have diabetes. It is the leading cause of blindness in North Americans under 65 years of age. Diabetes is a condition where the body either cannot produce enough insulin (胰岛素) or cannot respond properly to insulin. Insulin is important because it moves glucose (葡萄糖), a simple sugar, into the body"s cells from the blood. The food people eat provides the body with glucose, which is used by the cells as a source of energy. If insulin isn"t available or doesn"t work correctly to move glucose from the blood into the cells, glucose will stay in the blood, leading to high blood sugar levels.
High blood sugar levels damage the blood vessels, including the tiny blood vessels in the eye. This leads to an eye disease known as diabetic retinopathy (糖尿病型视网膜病). The retina (视网膜) is an area at the back of the eye that changes light into nerve signals. With diabetic retinopathy, some blood vessels in the retina are lost, and some of the other blood vessels begin to "leak" blood. This causes the retina to swell, and gradually cuts off its supply of oxygen and nutrients (滋养物). Eventually, the retina starts to grow new blood vessels to replace the damaged ones. Unfortunately, these new vessels are not as strong as the old ones. They are more likely to break, causing bleeding in the eye.
At first, people with diabetic retinopathy will not notice any symptoms. As the disease gets worse, they may notice blurred (模糊的) vision, black spots or flashing lights. As time goes on, it can progress to blindness. Everyone with diabetes is at risk for diabetic retinopathy, and the risk increases the longer you"ve had diabetes.
Fortunately, you can reduce your risk. If you do not have diabetes, but think you may be at risk for this condition, visit your doctor to be screened for diabetes. If you do have diabetes:
a) Have frequent eye check-ups.
b) Make sure that you monitor your blood sugar frequently and use your medications as recommended by your doctor. There is evidence to show that keeping your blood sugar under tight control can slow down eye damage.
c) If you have high blood pressure, follow your recommended diet and medications to keep it under control. If you are not sure whether you have high blood pressure, or whether your blood pressure is under control, discuss this with your doctor.

Freezing to Death for Beauty
People in Beijing wear a lot of clothing during winter to fend(抵御) off the
cold. In the United States, however, people wear {{U}}(51) {{/U}},
partly because the ear is the primary mode of transportation. Cars take

The American diet is full of calories, so their {{U}}(53) {{/U}} can
afford to burn heat more quickly. Fewer layers of clothing give
people the opportunity to stay {{U}}(54) {{/U}}. Lots of Yale girls wear

Some of them at least wear boots, tights(裤袜), and leg-warmers(暖腿套). Some,
however, really just go for(选 择) the look {{U}}(56) {{/U}}the risk of
health. These girls have nothing to prevent their legs {{U}}(57) {{/U}}
the wind, and no socks to protect their feet. A mini skirt and a pair of
stilettos(细高跟鞋) are all that they wear. Typically, the ones
pursuing fashion are {{U}}(58) {{/U}}, with little body fat. Just by the
nature of their bodies, they are already at a disadvantage compared with normal

shorts and shower slippers in the midst of winter. It's not cute (喜人的).
Of course, people have the freedom to look whatever

{{B}}Florence Nightingale{{/B}} Florence Nightingale
was born in Florence, Italy, while her wealthy English parents were traveling in
Europe. As a child, she traveled to many places with her family and learned how
to speak several languages. When Nightingale was 17, she told
her family that she was going to help sick people. Her parents did not approve,
but Nightingale was determined. She traveled to hospitals all
over Europe. She saw that doctors were working too hard. She saw that patients
died because they did not get enough care. Nightingale felt that women could be
doing more to help doctors take care of sick people. Nightingale
knew that in order for nurses to do more, they needed special training in how to
take care of sick people. Nightingale went to a hospital in Germany to study
nursing. Then she returned to London and became the head of a group of women
called Gentlewomen During Illness. These women cared for sick people in their
homes. In 1854, England was fighting a war with Russia. War
reporters wrote about the terrible conditions in the hospitals that cared for
the wounded. People demanded that something be done about it. A leader of the
government asked Florence Nightingale to take some nurses into the war
hospitals. So, in November 1854, Nightingale finally got to work in a
hospital. She took along 38 nurses whom she had trained
herself. At first, the doctors on the battlefields did not want
Nightingale and her nurses in their hospitals. They did not believe that women
could help. But in fact, the nurses did make a difference. They worked around
the clock, tending the sick. Thanks to their hard work, many wounded soldiers
survived. After the war, Nightingale and her nurses were treated
like heroes. Finally, in 1860, she started the Nightingale School for Nurses. In
time, thanks to Florence Nightingale, nursing became an important part of
medicine.
