1.单项选择题根据下列文章,请回答 23～30 题。
Ford
1 Ford’s great strength was the manufacturing process——not invention. Long before he stoned a car company，he was a worker. known for picking up pieces of metal and wire and turning them into machines. He started putting cars together in 1891'.Although it was by no means the first popular automobile，the Model T showed the world just how creative Ford was at combining technology and market.
2 The company’s assembly line alone threw America’s Industrial Revolution into overdrive（高速运转）。Instead of having workers put together the entire car，Ford’s friends，Who were great toolmakers from Scotland. Organized teams that added parts to each Model T as it moved down a line. By the time Ford's Highland Park plant was humming（嗡嗡作响）along in 191 4，the world's first automatic conveyor belt could turn out a car every 93 minutes.
3 The same year Henry Ford shocked the world with the$5.a.day minimum wage scheme，the greatest contribution he had ever made. The average wage in tile auto industry then was$2.34 for a 9-hour shift. Ford not only doubled that. he also took an hour off the workday. In those years it was unthinkable that a man could be paid that much，f0.r doing something that didn't involve an awful lot of training or education. The Wall Street Journal called the plan” an economic crime'，and critics everywhere laughed atF0rd.
4 But as the wage increased later to daily$10，it proved a critical component of Ford’s dream to make the automobile accessible（可及的）to all. The critics were too stupid to understand that because Ford had lowered his costs per car，the higher wages didn't matter——except for making it possible for more people to buy cars.

9.单项选择题根据下列文章,请回答 36～40 题。 Too Late to Regret It
When I was a junior, I met a second-year student in my department. He wasn't tall or good-looking, but he was very nice, attractive and athletic. He had something that I admired very much. He was natural, warm, and sincere.
I disregarded (不顾) my parents' disapproval. We were very happy together. He picked me up from my dorm every morning, and after class we would sit alongside the stream that ran through campus, or sunbathe (晒太阳) on the lawn. At night he would walk me back to my dorm. He came from a poor family, but in order to make me happy, he borrowed money from his friend to buy presents and meals for me. Our fellow students looked up to him as a role model, and the girls envied (妒忌) me. He wasn't a local, but wanted to stay here after graduation. I thought we had a future together.
However, when I got a part-time job during the summer vacation, people began giving me a lot of pressure, saying that a pretty, intelligent girl like me should find a better guy to spend time with. This was also what my family thought. He spent the summer in his hometown, so I was all by myself. When he got back, I began finding fault with him. But his big heart and warmth soon drove all unpleasant thoughts away. However, I had no idea how badly I had hurt him and that things would get worse.
I had a good part-time job off campus that paid pretty well. With my good performance at school, I also got admission to graduate school at one of China's best universities. He, on the other hand, did not do so well at school or at work. I had to worry about his living expenses, job and scores.
Almost all my colleagues and friends advised me to break up with him. Then we had a quarrel last June. He was in great pain, and my cold words and bad moods started turning him away.
Graduation time was drawing near, and he said he wanted to go back to his hometown. He said that he couldn't put up with me anymore. I was shocked and looked at him in despair,True love happens only once, but I found it out too late.
