10 阅读理解。 When I was nine years old I lived in a small town. I found an ad for selling greeting cards in the back of a children"s magazine. I thought to myself I could do this. I begged my mother to let me send for the kit (配件). Two weeks later the kit arrived. The next three hours later, I returned home with no card and a pocket full of money shouting, "Mama, all the people couldn"t wait to buy my cards!" A salesperson was born. When I was twelve years old, my father took me to see Zig Ziegler. I remember sitting in the dark hall listening to Mr. Ziegler raise everyone"s spirits up to ceiling. I left there feeling like I could do anything. When we got to the car, I turned to my father and said, "Dad, I want to make people feel like that." My father asked me what I meant. "I want to be a motivational speaker just like Mr. Ziegler," I replied. A dream was born. Recently, I began pursuing my dream of motivating others. I realized that everything I had accomplished - the graduate degree, the successful sales career, speaking appointments, training and managing for a major fortune 100 company as a senior manager- had prepared me for this moment. I told my boss who was a great leader I would leave the company though I might not reach such a height in career. He told me to proceed and he believed I would succeed. Having made that decision, I was immediately tested. One week after I gave notice, my husband was laid off from his job. We had recently bought a new home and needed both incomes to make the monthly mortgage (抵押) payment and now we were done to no income. I even planned to turn back to my former company, knowing they wanted me to stay but I was certain that if I went back, I would never leave. I decided I still wanted to move forward rather than end up with a mouth full of "if onlys" later on. A motivational speaker was born. When I held fast to my dream, even during the tough times, the miracles(奇迹) really began to happen. In a short time period my husband found a better job. We didn"t miss a mortgage payment. And I was able to book several speaking appointments with new clients (客户). I discovered the incredible power of dreams. I loved my old job, my workmates and the company I left, but it was time to get on with my dream. To celebrate my success I had a local artist paint my new office as a garden. At the top of one wall she marked, " The world always makes way for the dreamer." 1.Why was the kit sent for? A. Selling greeting cards. B. Collecting greeting cards. C. Buying greeting cards. D. Sending greeting cards. 2.When did the author decide to become a motivational speaker? A. After buying a new home by mortgage. B. After giving notice to leave her secure position in the company. C. After finding a job in a major fortune 100 company. D. After listening to Mr. Ziegler"s inspiring speech. 3.Which of the following statements is NOT TRUE? A. She was once an excellent manager. B. She left her post at the height of her career. C. She was not sure whether the former company could accept her. D. She didn"t miss paying the monthly mortgage payment. 4. What does the underlined sentence mean in the last paragraph? A. Carry on with your dreams and you will be successful. B. Risk everything you have for a dream and you will succeed. C. The world belongs to dreamers. D. Everyone will find their dreams.
