1.The person that I admire the most is scientist Stephen William Hawking. He was born on the 8th January 1942, in Oxford, England. Stephen is famous for his work on the basic laws of the universe. He is also famous for the way he coрes with having Motor Neuron Disease (MND). 2 Stephen studied Physics at University College, Oxford. He was diagnosed with MND while still at university. Stephen slowly lost control of his muscles and eventually he couldn't walk. Despite this, he finished his studies, got married and started a career at the university. 3 Some years later, he lost his voice completely. Unfortunately, he was in the middle of writing a book at the time and suddenly had no way to communicate other than linking. Today, a computer system on his wheelchair enables him to speak. Of his many books, A Brief History of Time is Stephen's bestseller. The reason I admire him is beсause he is very intelligent and brave, and he never gives up on life. When lthink of him, I know that anything is possible as long as you really want it and work hard to achieve it. Пж краткое содержание этого текста.​
