上海交大网络第五次作业and答案

Exercise Fivepound DictationI believe in toughness,steeliness and even meanness.I learned these(1)traits from my father.Toughness came first.I am the first-born and the son he never had.I’m the one he took to the gym,the one who could run faster than the boys,the one who played all day with a broken collarbone(锁骨).I’m the one who thought my daddy was the toughest man around—and I wanted to be just like him.He never missed a day of school,worked as a dishwasher to pay his college(2)tuition,and toiled as an accountant by day and attended law school at night.My dad also taught me steeliness,an unwillingness to(3)surrender.Steeliness kept me from being raped once.I fought my attacker.I left an imprint of my phone on his face.I(4)memorized details of his face and clothing.Determined to keep other women from being violated,I identified him,testified against him and made sure he went to jail.Sometimes even toughness and steeliness aren’t enough.I also believe in meanness.I am not a large woman;petite,in fact.I cannot command respect with my presence and stature. As a(5)community college English instructor in a tough town,I teach people who aren’t always eager to learn.I’m the mean teacher.I like to push students harder than they want to be pushed. Some of them don’t like me at the time,but they usually end up(6)appreciating me later on.“Hate me now,love me later”is my motto.I’m even mean with myself.Sometimes it’s meanness that gets me out of bed in the morning,like after a night of drinking too much.I’m not nice to myself—I don’t give myself(7)permission to stay home.Some of my best teaching days have been the result of my refusal to make others suffer for my poor(8)self-discipline.Meanness with myself keeps me accountable.That tough and steely will my father gave me helps me bear the loss of him.(9)I watched him die of cancer,but he never gave up on wanting to live.(Please pause here for30’’-40’’)Perhaps it would have been easier on both him and the family had he given in to death,had he not fought to the absolute last breath.(10)Although I do not have him in my life anymore,I got to see him as himself to the very end of his.(Please pause here for30’’-40’’)I understand the poet Dylan Thomas,who pleads with his own father to“rage,rage against the dying of the light.”Women are usually encouraged to be gentle.But when life has tested me the most,(11)I believe it’s my toughness,my steeliness and even my meanness that get me through.(Please pause here for30’’-40’’)Section2.Note-taking1)successful movie actress(for many years starting)2)star of a very popular radio program3)radio performer4)I love Lucy/TV show5)housewife6)to be in show business7)soft and pretty8)mean9)Cuba immigrant10)a bandleader(in a New York nightclub)Section3.Short Answering Questions.We might not be alone in the universe.Actually,it may be confirmed as a very crowded place by new computer models developed to help identify habitable planets.Estimates of places that can sustain life have been based on the likelihood of them having surface water.But software recently developed by the Aberdeen University allows researchers to identify planets with underground water kept liquid by planetary heat.Water is fundamental for life and planets too close to the sun lose water to the atmosphere through evaporation.On the other hand,planets located in distant reaches from their star have their surface water locked away as ice.Sean McMahon,who is carrying out the work,explained:“Traditionally people have said that if a planet is in this Goldilocks zone–not too hot and not too cold-then it can have liquid water on its surface and be habitable.”But this perception might change when considering that planets can receive two sources of heat-heat direct from the star and heat generated deep inside the planet.It is easy to observe it in our own planet.As you descend through the crust of the Earth,the temperature gets higher and higher.Even when the surface is frozen,water can exist below ground. There could be5.immense quantities of water in fact-teeming with primitive life.Professor John Parnell,also from Aberdeen University said:“There is a significant habitat for5. microorganisms below the surface of the Earth,extending down several kilometres.”“And some believe that the bulk of life on Earth could even reside in this deep biosphere.”So the Aberdeen team are developing models to predict which far-flung planets might harbour underground reservoirs of liquid water with the possibility of alien life.Section4.Listening and Translation1.As the human population has grown and become wealthier,the demand for high-quality animal protein has skyrocketed.For example,from1990to2005,Asia alone added roughly one billion humans,but10billion chickens,according to UN figures.Farmers are raising more animals in smaller spaces than in the past and in places that have not been used this way before.例如，根据联合国的统计数字，从1990年到2005，仅亚洲大约增加了10亿人口，但鸡却增加了100亿只。
