1 阅读理解。 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 Englishes 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 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 was 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 Englishes 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. 1.

A. she uses English in foreign trade B. she is fascinated by languages C. she works as a translator D. she is a writer by profession 2. The author used to think of her mother"s English as _____.

10 完形填空。 I grew up poor-living in the housing projects (住房) with six brothers, three sisters, a varying assortment (各式各样东西的混合) of foster kids (养子), my father, and a wonderful mother, Scarlette Hunley. We had little money and few worldly goods, but plenty of love and attention. I was 1 and energetic. I understood that no matter how poor a person was, he could still 2 a dream. My dream was 3 . By the time I was sixteen, I could crush a baseball, and hit anything that moved on the baseball field. I was also 4 : My high school Coach Jarvis, who not only believed in me, but taught me how to believe in myself. He 5 me the difference between having a dream and showing conviction (信念). One particular incident with Coach Jarvis changed my life forever. It was the summer between my junior and senior years, and a friend 6 me for a summer job. This meant a chance for money in my pocket-cash for dates with girls, certainly, money for a new bike and new clothes, and the 7 of savings for a house for my mother. The prospect of a summer job was attractive and interesting, and l wanted to jump at the opportunity. Then I realized I would have to 8 summer baseball to handle the work schedule, and that meant I would have to tell Coach Jarvis I wouldn"t be playing. When I told Coach Jarvis, he was 9 as I expected him to be. "You have your whole life to work," he said. "Your 10 days are limited. You can"t afford to waste them." I stood before him with my head hanging, trying to think of the words that would explain to him why my dream of buying my mom a house and having money in my pocket was worth facing his 11 to me. "How much are you going to make at this job, son?" He demanded. "3.5 dollars an hour." I replied. "Well," he asked, "Is $3.5 an hour the price of a dream?" That question, the plainness of it, laid here for me the difference between wanting something right now and having a goal. I delicated myself to sports that summer and with the year I was hired by the Pittsburgh Pirates to play baseball, and was 12 a $20,000 contract. I signed with the Denver Broncos in 1998 for $1.7 million, and bought my mother the house of my dreams. ( )1. A. happy ( )2. A. live ( )3. A. athletics ( )4. A. right ( )5. A. persuaded ( )6.
