3 Computers李仕才【阅读理解插花】I am a writer. I spend a great deal of my time thinking about the power of language—the way it can evoke(唤起)an emotion, a visual image, a complex idea, or a simple truth. Language is the tool of my trade. And I use them all—all the English I grew up with.Born into a Chinese family that had recently arrived in California, I’ve been giving more thought to the kind of English my mother speaks. Like others, I have described it to people as “broken” English. But I feel embarrassed to say that. It has always bothered me that I can think of no way to describe it other than “broken”, as if it were damaged and needed to be fixed, as if it lacked a certain wholeness. I’ve heard other terms used, “limited English”, for example. But they seem just as bad, as if everything is limited, including people’s perceptions(认识)of the limited English speaker.I know this for a fact, because when I was growing up, my mother’s “limited” English limited my perception of her. I wa s ashamed of her English. I believed that her English reflected the quality of what she had to say. That is, because she expressed them imperfectly her thoughts were imperfect. And I had plenty of evidence to support me: the fact that people in department stores, at banks, and at restaurants did not take her seriously, did not give her good service, pretended not to understand her, or even acted as if they did not hear her.I started writing fiction in 1985. And for reasons I won’t get into today, I began to write stories using all the English I grew up with: the English she used with me, which for lack of a better term might be described as“broken”, and what I imagine to be her translation of her Chinese, her internal(内在的)language, and for that I sought to preserve the essence, but neither an English nor a Chinese structure.I wanted to catch what language ability tests can never show: her intention, her feelings, the rhythms of her speech and the nature of her thoughts.【文章大意】本文主要记叙了作者在不同时期对母亲所利用的语言的不同观点。
