Philo was born on August 19th, 1906, near Indian Creek in the western state of Utah. He attended a very small school near his family’s farm. He did very well in school. He asked his teacher for special help in science. The teacher began helping Philo learn a great deal more than most young students could understand. One night, Philo read a magazine story about the idea of sending pictures and sound through the air. Anyone with a device that could receive this electronic information could watch the pictures and hear the sound. The magazine story said some of the world’s best scientists were using special machines to try to make a kind of device to send pictures. 14yearold Philo decided these famous scientists were wrong and that mechanical devices would never work. He decided that such a device would have to be electronic. Philo knew electrons(電子 ) could be made to move extremely fast. All he would have to do was to find a way to make electrons do the work. Very quickly Philo had an idea for such a receiver. It would trap light in a container and send the light on a line of electrons. Philo called it “l(fā)ight in a bottle”. Several days later, Philo told his teacher about a device that could capture(捕獲 ) pictures. He drew a plan for it, which he gave his teacher. Philo’s drawing seemed very simple, but it clearly showed the information needed to build a television. In fact, all television equipment today still uses Philo’s early idea. Philo Farnsworth was only 14 years old then. He knew no one would listen to a child. Experts say that probably only ten scientists in the world at that time could have understood his idea. On September 7th, 1927, Philo turned on a device that was the first working television receiver. In another room was the first television camera. Philo had invented the special camera tube earlier that year. The image produced on the receiver was not very clear, but the device worked. In 1930, the United States government gave Philo patent documents(專利 ). These would protect his invention from being copied by others. 53. Before he was 14 years old, . A. Philo had had a very strong interest in science B. Philo had learned a great deal in science from his father C. Philo had helped his parents on their family’s farm D. Philo had formed the idea of sending pictures and sound through the air 54. The underlined word “it” in the fourth paragraph refers to . A. a container sending pictures and sound through the air B. a receiver that held light and sent it on a line of electrons C. a light box with a line of electrons in a bottle D. a way to make electrons send pictures 55. We can infer from the text that Philo’s idea . A. was not recognized at first B. was only understood by his teacher C. was turned into a television receiver immediately D. was widely used in all television equipment in 1927 第二節(jié) 根據(jù)短文內(nèi)容 , 從短文后的選項中選出能填入空白處的最佳選項 , 選項中有兩項為 多余選項。 (每小題 2 分 , 滿分 10 分 ) We often close ourselves off when painful events happen in our life. Instead of letting the world soften us, we let it drive us deeper into ourselves. 56 The item listed below are four tips you can open your heart more fully and pletely. 1. Breathe into pain Whenever a painful situation arises in your life, try to face it instead of running away. 57 When the sadness strikes, take a deep breath and accept it. By using our breath, we soften our experiences and allow more newness. 2. 58 We’re often confused at the next step to take. Actually, we can try a new decision making process. To start the process, we may ask, “Heart, what decision should I make here? What action feels the most right?” See what es up, then put it into practice and evaluate the oute. 3. Spend time alone
