单选题The United States is a country made up of many different races. Usually they are mixed together and can"t be told from one another. But many of them still talk about where their ancestors came from. It is something they are proud of. The original Americans, of course were the Indians. The so-called white men who then came were mostly from England. But many came from other countries like Germany and France. One problem the United States has always had is discrimination. As new groups came to the United States they found they were discriminated against. First it was the Irish and Italians. Later it was the blacks. Almost every group has been able to finally escape this discrimination. The only immigrants who have not are the blacks. Surprisingly enough the worst discrimination today is shown towards the Indians. One reason the Indians are discriminated against is that they have tried so hard to keep their identity. Of course they are not the only ones who have done so. The Japanese have their Little Tokyo in Los Angeles and the Chinese a Chinatown in New York. The Dutch settlement in Pennsylvania also stays separate from other people. Their towns are like something from the 19th century. They have a different reason from the other groups for staying separately. They live separately for religious reasons rather than keep together in a racial group. Although some groups have kept themselves separate and others have been discriminated against, all groups have helped make the United States a great county. There is no group that has not helped in some way. And there is no group that can say they have done the most to make it a great country. Many people still come from other countries to help the United States grow. A good example is the American project that let a man walk on the moon. It was a scientist from Germany who was most responsible for doing that. It is certain that in the future the United States will still need the help of people from all racial groups to remain a great country.

单选题Fortunately there are still a few tasty things for us gourmands to enjoy in relative security. Their numbers, however, are depleted almost daily. It seems, by ruthless proclamations from the ever-vigilant Food and Drug Administration and its allies, our doctors. The latest felon to face prosecution is the salt of life, sodium chloride. Ostensibly, overuse of salt muses high blood pressure and hypertension, the cause of half the deaths in the United States every year. A few years ago the anti-salt campaigners raised such a rumpus that salt was banned from baby food. Currently pressure is being applied to food manufacturers to oblige them to label their products to show sodium content. Bemuse doing so would cost mercenary manufacturers money, they argue that they have no idea how much salt remains on such things as potato chips and how much sticks to the bag. Furthermore, salt isn't the only harmful ingredient in food. If the manufacturer has to provide sodium content, why not require him to list every ingredient and specify which are detrimental to our health? Cigarettes have a warning printed on them. Shouldn't the same type of warning appear on canned foods that are notoriously over-salted? There are endless ifs and buts in the controversy, but the most telling of these is the questionable proof of salt' s diabolic effect upon blood pressure. True, people who cut their salt intake lowered their blood pressure, but where is the scientific proof that something other than salt didn't do the trick? The most common means of providing dubious proof that salt causes hyper tension is to compare societies that use little salt with those that use mountains of salt in their daily diets. Which group has the higher rate of hypertension? Whose blood pressure is lower? What happens when salt is introduced into a group where salt is a novelty? Does the blood pressure rise significantly? Studies of the Japanese indicate that as the world's greatest salters, they suffer the most from hypertension. On the other hand, the simple, salt-free cuisine of several tribes in the Solomon Islands has kept older tribesmen and women from developing hypertension and high blood pressure, ailments traditionally killing their peers in America. No account is taken of the effects of inflation, recession, pollution, crime, and sundry other ills to which Americans unlike people on primitive islands, are exposed. To salt or not to salt? That is the question. Now that the question has arisen, it must not be treated with levity but, rather, with searching scientific investigation so that those of us who are preoccupied with both savory food and longevity may decide which of the two is worth its salt.
