听力原文：In most corners of the world malnutrition is plainly a matter of outright insufficiency of food for population -- where the majority of the people do not obtain enough food calories to meet minimal needs for support of physical work and for maintenance of health. Elsewhere the problem may be not one of insufficient calories but of lack of specific nutrients essential for health.
In Latin America, as in other places, the dread protein deficiency disease kwashiorkor is taking its heavy toll on children's lives. Strategic vitamins and minerals may be lacking due to traditional diets which are nutritionally imbalanced. Here people continue their eating pattern year after year without knowledge of what their dietary habits are doing to themselves and to future generation. With a basic knowledge of nutritional needs and deficiencies, efforts would be directed to finding food substitutes which could meet these needs. Mixtures of vegetable proteins, like soybeans and peanuts, could provide an abundance of cheap, useful protein where meats, eggs, and milk are not within economic reach of large groups in the population. Efforts could also be expanded on increasing the agricultural productivity in specific regions; where large areas are given over to relatively inefficient use as grazing land, the intensive production of vegetable protein crops could bring remedial nutrition to an undernourished population.
Cheap protein substitutes from milk, eggs and meat ______.
How many people of US population suffered compulsive buying disorder？
听力原文： Hi, everyone. As we mark the anniversary of the Iraq war, we're being reminded of all that our soldiers have sacrificed, and what some continue to experience. The scandal at Walter Reed put their suffering into sharp focus. And so was the new study from the Archives of Internal Medicine. The study found that about a third of veterny vets were diagnosed with mental illness or a psycho social disorder, everything from depression and post traumatic stress, to homeless and domestic violence. The highest rate of mental problems is among the youngest -- soldiers between 18 and 24. The doctor who conducted the study says the num-bets may eventually surpass those from Vietnam.
Bobby Miller, a Vietnam vet and a President of Veterans from America says, "We haven't even begun to understand the magnitude of this." "Attention," he says, "must be paid. Unless we want a 'lost generation'." I agree. That's a page from my notebook.
Which war is this passage to mark the anniversary of？
听力原文：Everybody loves the swimming pool. But how clean is the water in the average backyard or public pool？ If you trust chlorine to take care of germs, you're in for a surprise. Chlorine and other disinfectants do indeed help to clean the water, but some germs can survive in even the best-kept pool. For example, cryptosporidium may live in pool water for several days. Crypto causes a diarrheal illness and may rinse off the bodies of infected people or diapered children into the pool. If you swallow infected pool water, you may become sick. Other germs may live for a few minutes or a few hours in a chlorinated pool: Giardia, Shigella, and E. Coli may cause diarrheal illnesses. Pseudomonas Aeruginosa may cause an ear infection called swimmer's ear and also a skin infection called "hot tub rash", that is usually associated with very warm pools and spas. While keeping the correct chlorine and PH levels will minimize water-borne illness, prevention is also a good idea.Keep diapered children in the water for only brief periods and keep sick people out of the water altogether. And, don't ever swallow pool water.
According to the passage, how long may Cryptosporidium live in pool water？
