Are organically grown foods the best food choices？ The advantages claimed for such foods over conventionally grown and marketed food products are now being debated. Advocates of organic foods— a term whose meaning varies greatly—frequently proclaim that such products are safer and more nutritious than others.
The growing interest of consumers in the safety and nutritional quality of the typical North American diet is a welcome development. However, much of unsafe or inadequate in meeting nutritional needs. Although most of these claims are not supported by scientific evidence, the preponderance of written material advancing such claims makes it difficult for the general public to separate fact from fiction. As a result, claims that eating a diet consisting entirely of organically grown foods prevents or cures disease or provides other benefits to health have become widely publicized and form. the basis for folklore.
Almost daily the public is besieged by claims for "no-aging' diets, new vitamins, and other wonder foods, there are numerous unsubstantiated reports that natural vitamins are superior to synthetic ones, that fertilized eggs are nutritionally superior to unfertilized eggs, that untreated grains are better than fumigated grains, and the like.
One thing that most organically grown food products seem to have in common is that they cost more than conventionally grown foods. But in many cases consumers are misled if they believe organic foods can maintain health and provide better nutritional quality than conventionally grown foods. So there is real cause for concern if consumers, particularly those with limited incomes, distrust the regular food supply and buy only expensive organic foods instead.

听力原文： Mark Twain, who wrote the story we're reading, traveled quite a lot, often because circumstances, usually financial circumstances forced him to. He was born in Florida Missouri in 1835 and moved to Hannibal Missouri with his family when he was about four years old. Most people think he was born in Hannibal. But that isn't true. After his father died when he was about twelve, Twain worked in Hannibal for a while and then left so he could earn more money.
He worked for a while as a typesetter on various newspapers and then got a job as a river pilot on the Mississippi. Twain loved this job and many of his books show it. The river job didn't last however, because of the outbreak of the civil war. Twain was in the army for just two weeks and then he and his whole company went west to get away from the war and the army. In Nevada and California Twain tried to find silver and gold without much luck but did succccd as a writer.
Once that happened, Twain traveled around the country giving lectures and earning enough money to go to Europe. Twain didn't travel much during the last ten years of his life, and he didn't publish much either. Somehow his travels inspired his writing. Like many other popular writers, Twain derived much of the materials for his writing from the wealth of his own personal experiences.

W: Yeah, I know. You told me. I just thought two heads might be better than one.
