Unit1The American does not join in the argument but watches the other guests. As he looks, he sees a strange expression come over the face of the hostess. She is s taring straight ahead, her muscles contracting slightly. She motions to the nat ive boy standing behind her chair and whispers something to him. The boys eyes widen: he quickly leaves the room. Of the guests, none except the American notices this or sees the boy place a bo wl of milk on the veranda just outside the open doors. The American comes to with a start. In India, milk in a bowl means only one thi ng -bait for a snake. He realizes there must be a cobra in the room. Unit2Jeffersons courage and idealism were based on knowledge. He probably knew more than any other man of his age. He was an expert in agriculture, archeology, an d medicine. He practiced crop rotation and soil conservation a century before t hese became standard practice, and he invented a plow superior to any other in existence. He influenced architecture throughout America, and hewas constantly producing devices for making the tasks of ordinary life easier to perform.Of all Jeffersons many talents, one is central. He was above all a good and ti reless writer. His complete works, now being published for the first time, will fill more than fifty volumes. His talent as an author was soon discovered, and when the time came to write the Declaration of Independence at Philadelphia in 1776, the task of writing it was his. Millions have thrilled to his words: We hold these truths to be self-evident, that all men are created equalUnit3While I was waiting to enter university, I saw advertised in a local newspaper a teaching post at aschool in a suburb of London about ten miles from where I lived. Being very short money and wanting to do something useful, I applied, fe aring as I did so, that without a degree and with no experience in teaching my chances of getting the job were slim.However, three days later a letter arrived, asking me to go to Croydon for an i nterview. It proved an awkward journey: a train to Croydon station; a ten-minut e bus ride and then a walk of at least a quarter to feel nervous. Unit 5The sea level is rising very slowly from year to year. In all likelihood, it will continue to rise and do so at a greater rate in the course of the next hundred years. Where there are low-lying coastal areas (where a large fraction of the worlds population lives) the water will advancesteadily, forcing people to retreat inland.Eventually the sea will reach two hundred feet above its present level, and will be splashing against the windows along the twentieth floors of Manhattans skyscrapers. Florida will disappear beneath the waves, as will much of the British Isles, the crowded Nile valley, and the low-lying areas of China, India, and Russia.Not only will many cities be drowned, but much of the most productive farming areas of the world will be lost. As the food supply drops, starvation will be widespread and the structure of society may collapse under the pressureUnit 6Now, in the last month of my residency, sleeping was no longer a problem. There were still situations in which I couldnt be certain my decision had been the ri ght one, but I had learned to accept this as a constant problem for a surgeon, o ne that could never be completely resolved -and I could live with it. So, once I had made a considered decision, I no longer dwelt on it. Reviewing it wasnt g oing to help and I knew that with my knowledge and experience, any decision Id made was bound to be a sound one. It was a nice feeling.
