The Doctor in America
Self-employed private physicians who charge a fee for each patient visit have been the norm for American medical practice. Most physicians have a contract relationship with one or more hospitals in their community. They refer their patients as needed to the hospital, which usually charges according to the number of days a patient stays and the facilities - X-rays, operating rooms, tests -he or she uses.
Some medical doctors are on salary. Salaried physicians may work as hospital staff members, or residents, who are often still in training. They may teach in medical schools, be hired by corporations to care for their workers or work for the federal government's Public Health Service.
Physicians are among the best-paid professionals in the United States. In the 1980s, it was not uncommon for medical doctors to, earn incomes of more than $100,000 a year. Specialists, particularly surgeons, might earn several times that amount. Physicians list many reasons why they deserve to be so well rewarded for their work. One reason is the long and expensive preparation required to become a physician in the United States. Most would-be physicians first attend college for four years, which can cost nearly $20,000 a year at one of the best private institutions. Prospective physicians then attend medical school for four years. Tuition alone can exceed $10,000 a year. By the time they have obtained their medical degrees, many young physicians are deeply in debt. They still face three to five years of residency (住院医生实习期)in a hospital, the first year as an apprentice physician. The hours are long and the pay is relatively low.
Setting up a medical practice is expensive, too. Sometimes several physicians will decide to establish a group practice, so they can share the expense of maintaining an office and buying equipment. These physicians also take care of each other's patients in emergencies.
Physicians work long hours and must accept a great deal of responsibility. Many medical procedures, even quite routine ones, involve risk. It is understandable that physicians want to be well rewarded for making decisions which can mean the difference between life and death.

Facts about Stroke
1.Every 45 seconds,someone in America has a stroke.Every 3.1 minutes,someone dies of one.Stroke killed an estimated 167,661 people in 2000 and is the nation's third leading cause of death,ranking behind diseases of the heart and all forms of cancer.Stroke is a leading cause of serious,long-term disability in the United States.
2.Stroke is a type of cardiovascular(心血管的)disease.It affects the arteries(动脉)leading to and within the brain.A stroke occurs when a blood vessel that carries oxygen and nutrients(营养物)to the brain is either blocked by a clot(凝块)or bursts.When that happens,part of the brain cannot get the blood(and oxygen)it needs,so it starts to die.
3.The brain is an extremely complex organ that controls various body functions.If a stroke occurs and blood flow can't reach the region that controls a particular body function,that part of the body won't work as it should.If the stroke occurs toward the back of the brain,for instance,it's likely that some disability involving vision will result.The effects of a stroke depend primarily on the location of the obstruction(阻塞)and the extent of brain tissue affected.
4.The American Stroke Association has identified several factors that increase the risk of stroke.The more risk factors a person has,the greater the chance that he or she will have a stroke.Some of these you can't control,such as increasing age,family health history,race,and prior stroke.But you can change or treat other risk factors to lower your risk.Factors resulting from lifestyle or environment can be modified with a healthcare provider's help.Some of these include:high blood pressure,current smoking,heart disease,and high red blood cell count.
5.A stroke can happen to anyone at any moment.In fact about 600,000 people have strokes every year.For many years,there was no hope for those suffering a stroke.However,recent breakthroughs have led to new treatments.For the treatments to work,the person must get to a hospital immediately.

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:
Have frequent eye check-ups.
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.
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.

Read With Greater Speed
Do you have difficulty reading in class? If so, a special reading program that helps match sounds with letters could speed up your brain.
At least one out of every five elementary school students in the US has trouble learning to read, even when the students are good at other subjects. __________(1)
Researchers from Yale University, US, studied a group of children from New York and Connecticut State. As part of the study, 37 struggling readers received special tutoring.
Every day, instructors worked with them on recognizing how written letters represent units of sound called phonemes (音素). __________(2)
By the end of the school year, these children could read faster than before. They also made fewer mistakes, and understood more of what they read than they could earlier in the year.
As part of their study, the researchers used a special machine to take action photos of the students' brains.
(3)__________ This is the same part of the brain that becomes active when good readers read. This activated brain area appears to include a structure that helps people recognize familiar written words quickly. In lower level readers, this structure remains inactive.
A.year later, the brain structure was still working hard in the students who had gore through the special tutoring, and they continued to do well in reading tests __________(4)
However, some researchers still doubt the study. __________(5)
A Many adults are interested in matching sounds with letters
B The students also practiced reading aloud and spelling
C The biggest challenge for many of these kids, scientists say, is matching sounds with letters.
D Another group in the study who went through a more traditional reading program didn't show the same progress.
E The pictures showed an increase in activity in the back of the brain on the left side.
F They believe that reading without making any noise or linking words to sounds is more efficient.
