Diabetes (糖尿病) and Eye DamageOver 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, to 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. Glucose cannot be turned into energy in the body ______.
The book shows only a superficial understanding of the historical context.
Learning to ForgiveTo forgive may be divine, but no one ever said it was easy. When someone has deeply hurt you, it can be extremely difficult to let go of yourgrudge. But forgiveness is possible, and it can be surprisingly beneficial to your physical and mental health."People who forgive show less depression, anger and stress and more hopefulness," says Frederic Luskin, Ph. D. , author of Forgive for Good. "So it can help save on the wear and tear on our organs, reduce the wearing out of the immune system and allow people to feel more vital."So how do you start the healing Try following these steps:Calm yourself. To defuse your anger, try a simple stress-management technique. "Take a couple of breaths and think of something that gives you pleasure: a beautiful scene in nature, or someone you love," Luskin says.Don"t wait for an apology. "Many times the person who hurt you has no intention of apologizing," Luskin says. "They may have wanted to hurt you or they just don"t see things the same way. So if you wait for people to apologize, you could be waiting an awfully long time." Keep in mind that forgiveness does not necessarily mean reconciliation with the person who upset you or condoning of his or her action.Take the control away from your offender. Mentally replaying your hurt gives power to the person who caused you pain. "Instead of focusing on your wounded feelings, learn to look for the love, beauty and kindness around yon," Luskin says.Try to see things from the other person"s perspective. If you empathize with that person, you may realize that he or she was acting out of ignorance, fear, even love. To gain perspective, you may want to write a letter to yourself from your offender"s point of view.Recognize the benefits of forgiveness. Research has shown that people who forgive report more energy, better appetite and better sleep patterns.Don"t forget to forgive yourself. "For some people, forgiving themselves is the biggest challenge," Luskin says. "But it can rob you of your self-confidence if you don"t do it." According to the passage ,which of the following statements of forgiveness is NOT true
A woman goes to work for a large corporation like IBM. She is intelligent, ambitious and hard-working. She is also good at solving problems. She likes the security of a definite salary and the security of knowing that there will always be a defined job to be done, a definite direction in which to exert her abilities. Perhaps the consciousness that ability will be rewarded is also important. A man goes to work for the government service. He is competent and hard-working, but he is not ambitious. He does not like to work under pressure or in a competitive environment. His real interests lie outside work in his lore of music. A brash young man who wants only to work for himself proceeds to set up his own business, starting with a hamburger franchise for which he borrows money. His satisfaction is to see things happen. He wants to be able to make things happen. He wants to look at the accounts at the end of the month and see what has happened. He wants the maximum responsibility and the maximum reward; he does not mind the risk. It is the urge to bring something about that defines the entrepreneur. This urge is not unlike that of the painter or writer. There is an urge to make something happen, something that was not there before. The medium chosen by the entrepreneur is action or operation. The aesthetic satisfaction is that of seeing something happening effectively, of seeing decisions correctly made. This satisfaction is made concrete by money. Money is the indicator of success but not necessarily the driving factor. The test would be simple: if an entrepreneur were suddenly given as much money as he wanted, would he stop his activities or use the money to develop new ones History is very much on the side of the new activities. The entrepreneur seeks out opportunities; he tries things out; he makes decisions based as much on hunch as on analysis. Quite often he starts up a successful business which grows to such a size that his entrepreneurial style of management is no longer the best and he has to resign if the company is to survive. Entrepreneurs are the risk element in society, the evolutionary element that brings about change as distinct from the operating element that keeps things ticking over. In too many countries they are discouraged as being greedy and selfish.
