单选题{{B}}第三篇{{/B}} Malnutrition (营养不良) A new World Bank report warns that children who don't get enough good food in the first two years of life suffer lasting damage. They may be underdeveloped or underweight. They may suffer from poor health or limited intelligence. In addition, poorly nourished children are more likely to drop out of school and earn less money as adults. The report notes that too little food is not the only cause of poor nutrition. Many children who live in homes with plenty of foods utter for other reasons. For example, the study says that mothers often fail to give their newly born babies their first breast milk. This milk-like substance is called colostrum. It is full of nutrients that improve a baby's ability to fight infections and disease. The study also links malnutrition to economic growth in poor countries. A lack of nutrition in early children can cost developing nations up to three percent of their yearly earnings. Many of these same countries have economies that are growing at a rate of two or three percent yearly. The study suggests that poor countries could possibly double their economic growth if they improved nutrition. Africa and South Asia are affected the most by poor nutrition. The study says about half of all children in India do not get enough good food. The World Bank study also notes that rates of malnutrition in South Asia are almost double those in central and southern Africa. Other parts of world are also severely affected, including Indonesia, Uzbekistan, Yemen, Guatemala and Peru. The study recommends that developing countries change their policies to deal with malnutrition. Instead of directly providing food, the study suggests educational programs in health care. World Bank nutrition specialist Meera Shekar said the period of life between pregnancy and two years was extremely important. Governments with limited resources should take direct action to improve nutrition for children during this period.

Nicotine (尼古丁) patches axe small, nicotine-containing adhesive (黏着性的) discs applied to the skin. The nicotine is slowly absorbed through the skin and enters the bloodstream. Over time, the nicotine dose is reduced and eventually the desire for nicotine is eased. Nicotine gum works in a similar manner, providing small doses of nicotine when chewed. The benefits of giving up smoking include the immediate reduction of harm to the health of the smoking and easily admission to social activities and institutions that ban smoking. In a 1988 report, the US Surgeon General declared cigarette smoking to be more harmful and expensive than the use of cocaine (可卡因), alcohol, or heroin. Recent evidence supports this claim. The United States government has collected a special tax on cigarettes for several decades. The rate rose from 8 cents per pack of 20 cigarettes in 1951 to 24 cents per pack in 1993. In other developed countries, the cigarette tax rate is much higher, ranging from 50 percent in Switzerland to 85 percent in Denmark. In the United States, the first direct action to check smoking was the regulation of a warming on cigarette packages by the Federal Trade Commission. This warning took effect in 1964 and was strengthened in 1969 to read: "Warning: The Surgeon General Has Determined That Cigarette Smoking Is Dangerous to Your Health." In 1971 all cigarette advertising was banned from radio and television, and cities and states passed laws requiring nonsmoking sections in public places and workplaces.
