Dyslexia is a term used to describe a marked difficulty in learning to read despite normal intelligence and vision. The problem is universal, but research suggests it doesn’t affect every culture or language group equally. On China’s mainland and in Japan, for example, dyslexia rates are estimated at less than 5 percent compared to 10 percent to 20 percent in the U.S. There are intriguing theories as to why, and Japan has produced some important clues.
Japanese children first learn to read and write in parallel phonetic alphabets, hiragana(平假名) and katakana(片假名), each containing 46 characters relating to 46 different sounds. After conquering them, the student starts to learning Chinese characters. According to Uno, who works for Japan’s National Center of Neurology and Psychiatry, just 1 percent of Japanese students have dyslexic problems with Chinese characters. The numbers jump a bit when it comes to writing --- 2 percent for hiragana, 3.8 percent for katakana and 5 percent for ideograms --- but they’re still low by American standards.

查看习题详情和答案>>The food we eat seems to have a great effect on our health. Although science has made big steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of human illness is related to food and forty percent of cancer is related to food as well. That food is related to illness is not a new discovery. In 1945, some researchers realized that things commonly used to keep colour in meats and other food additives(添加剂)caused cancer.
Yet, these additives remain in our food, and it is difficult to know which things on the wrappings(包装)of foods are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to their animals, and because of this, penicillin has been found in the milk of cows. Sometimes similar things are supplied to animals not for their health, but just to make a profit.
The farmers are simply trying to fatten the animals in order to get a higher price on the market. Although some countries have tried to control such things, the practice continues.
