单选题Questions 53 to 56 are based on the following passage: 　　With the widespread and still growing use of personal computers, typing has become an indispensable part of our ordinary lives. As a result, many users now find they can't write even familiar words though they can type them quickly and correctly on a computer keyboard. To make matters worse, some people even forget how to write at all. Currently, 90 percent of students in America, a nation which has completely adapted to everyday use of computers and the Internet, are unable to write properly and clearly because they have been typing onto keyboards since early childhood. Many younger teachers also have trouble writing clearly on blackboard. A university student never imagined that he would lose the chance to get his first job because of his handwriting problem. Another student, for fear that she wouldn't be able to write well when doing the test papers for the university entrance examination, quit using a computer for two months before the exam. "It is not surprising," an expert of psychological medicine said. "The occurrence can be attributed to several factors. Firstly, it's the result of social developments and the work needs of constant computer use. Secondly, it relates to introverted (~ Ih] ~) personal character and lack of self-control abilities especially for those students who indulge in playing computer games." Experts also think that many activities on computers make people's thoughts simplified, which also affects their lives in other aspects, such as how they communicate with others and the way they think. Writing can strengthen human body's functions in psychology and physiology, which cannot be substituted by typing into a computer. Relevant research indicates that inscribing or drawing something on paper can leave a deep impression in the language processing areas of the central nervous system in the brain. This process does not occur when typing on a computer. Experts' tips are arranging work time well and paying particular attention to not working in front of the screen for long periods of time and trying to read books and writing down something, such as keeping a diary or making notes with a pen regularly--it's a good way to strengthen the formation of words in one's memory.
