Установите соответствие между заголовками 1–8 и текстами A–G. Запишите свои ответы в таблицу. Используйте каждую цифру только один раз. В задании есть один лишний заголовок. 1. Education: the Way to the Top 2. From Agony to Love 3. Teaching to Learn 4. Learning That Never Stops 5. Things Worth Learning 6. The Right Word Can Bring Changes 7. What My Father Taught Me 8. The Power of Numbers A. Education has the power to transform a person’s life. I am the living example of this. When I was on the streets, I thought I was not good at anything but I wrote a poem, and it got published. I went back to school to learn. I have learned the benefit of research and reading, of debate and listening. One day soon a group of fresh-faced college students will call me professor. B. Language has the capacity to change the world and the way we live in it. People are often afraid to call things by their direct names, use taboos not to notice dangerous tendencies. Freedom begins with naming things. This has to happen in spite of political climates, careers being won or lost, and the fear of being criticized. After Helen Caldicott used the word ‘nuclear arms race’ an anti-nuclear movement appeared. C. I never wanted to be a teacher. Yet years later, I find myself teaching high school English. I consider my job to be one of the most important aspects of my life, still I do not teach for the love of teaching. I am a teacher because I love to learn, and I have come to realize that the best way to learn is to teach. D. One day my sister and I got one and the same homework. My sister finished the task in 2 minutes and went off to play. But I could not do it, so I went into my sister’s room and quickly copied her work. But there was one small problem: my father caught me. He didn’t punish me, but explained that cheating makes people feel helpless. And then I was left feeling guilty for cheating. E. Lifelong learning does not mean spending all my time reading. It is equally important to get the habit of asking such questions as ‘what don’t I know about this topic, or subject?’, ‘what can I learn from this moment or person?’, and ‘what more do I need to learn?’ regardless of where I am, who I am talking to, or what I am doing. F. Math has always been something that I am good at. Mathematics attracts me because of its stability. It has logic; it is dependable and never changes. There might be some additions to the area of mathematics, but once mathematics is created, it is set in stone. We would not be able to check emails or play videogames without the computer solving complex algorithms. G. When my high school English teacher asked us to read Shakespeare, I thought it was boring and too difficult. I agonized over the syntax — I had never read anything like this. But now I am a Shakespeare professor, and enjoy teaching Hamlet every semester. Each time I re-read the play, I find and learn something new for myself.
