单选题It's surprisingly easy for a person to amputate (切除) part of a finger - for instance, while chopping vegetables or using an electric saw. Don't try to preserve the loose part by placing it directly on ice. Do wrap the severed part in damp gauze (纱布) (saline (生理盐水) would be ideal for wetting the cloth), place it in a watertight bag and place the bag on ice. Then be sure to bring the bag and ice to the emergency room. The patient will be going into surgery, so he's best off with an empty stomach. As for the wound on the hand or body, apply ice to reduce swelling and cover it with a clean, dry cloth. Ice should be applied to the wound on the hand or body toA. reduce swelling.B. keep the cut clean.C. reduce pain from the wound.D. keep the wound wet.

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: 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.

单选题U.S. to Start $3.2 Billion Child Health Study in January A study that will cost $3.2 billion and last more than two decades to track the health of 100,000 U.S. children from before birth to age 21 will be launched in January, U.S. health officials said on Friday. Officials from the U.S. government"s National Institutes of Health said they hope the study, to be conducted at 105 locations throughout the United States, can help identify early-life influences that affect later development, with the goal of learning new ways to treat or prevent illness. The study will examine hereditary and environmental factors such as exposure to certain chemicals that affect health. Researchers will collect genetic and biological samples from people in the study as well as samples from the homes of the women and their babies including air, water, dust and materials used to construct their residences, the NIH said. Officials said more than $200 million has been spent already and the study is projected to cost $3.2 billion. "We anticipate that in the long term, what we learn from the study will result in a significant savings in the nation"s health care costs," Dr. Duane Alexander, who heads the NIH"s Eunice Kennedy Shriver National Institute of Child Health and Human Development, told reporters. The study will begin in January when the University of North Carolina and the Mount Sinai School of Medicine in New York start signing up pregnant women whose babies will then be followed to age 21. Some of the early findings will be about factors behind pre-term birth, which has become more common in recent years, according to Dr. Peter Scheidt of the NIH, who heads the study. The people taking part will be from rural, urban and suburban areas, from all income and educational levels and from all racial groups, the NIH said.

单选题Immigration and Problems Hundreds of thousands of people supporting immigration fights in the U.S. filled streets all over America in early 2006. Many held signs and American flags and asked to be treated as citizens not criminals. Many of these supported legislation from Senator John McCain that would open a path to citizenship to immigrants who were already in the country illegally. Proposed legislation from other politicians called for stricter measures, including rounding up undocumented immigrants and sending them back to their home countries. Canadian officials say that immigration applications continue to rise. Some want to keep the doors open. They need the labor. About 400,000 immigrants were allowed into the country in 2005, according to the Canadian Government statistics. However, all this growth means that cities need to adapt. Newcomers don't always make a smooth transition into jobs for which they are skilled. So industries are using mentoring programs to help new immigrants find proper jobs. With the large numbers of undocumented African immigrants arriving in the Canary Islands and showing no sign of abating, the Spanish Government has decided to get tough. There will be no more mass amnesties for illegals, and anyone coming to Spain without permission will be sent back, the government has announced. About 23,000 migrants landed on the islands in 2006, and riots have erupted in some crowded reception centers. This has promoted local authorities to appeal to the United Nations for help. France's new immigration and integration law gives the government new powers to encourage high-skilled migration. It takes effect in 2007. The new law authorizes the government to identify particular professions where France has a talent shortage. Then the government will help these identified employers find immigrant workers with needed skills or qualifications. The selected foreign employees will be granted "skills and talents" visas, valid for three years. But some concern that it'll cause brain drain in developing countries.
