Section Ⅲ Lesson 2 Lesson 3—Pre-reading[原文呈现]Epidemics throughout historyWith recent press① reports drawing parallels② between Bird Flu and a killer epidemic③ in the past, Jim Smith looks through④ the history of epidemics for clues about what the future might hold.Since Bird Flu first appeared in 1997, it has taken more than a hundred lives⑤. Many people fear it could be the next global epidemic, especially as scientists who studied tissue⑥ from the bodies of people who died of⑦ the 1918 Spanish Flu proved that Bird Flu is a modern adaptation⑧ of the same virus⑨.Bacteria and viruses have been around since the beginning of life on Earth and many of today's diseases have existed as long as⑩ humans have. It is important to look at⑪ the spread of diseases throughout history⑫ to discover the causes and effects⑬ of epidemics, and hopefully, foresee⑭ and prevent them in the future.[读文清障]①press/pres/n.新闻界；报界②parallel/'pærəlel/n.极相似之处；平行线③epidemic/ˌepI'demIk/n.流行病④look through看穿；审核，浏览⑤take one's life夺走某人的生命⑥tissue/'tIʃuː/n.组织⑦die of死于(饥饿、寒冷、疾病等身体内部因素)die from死于(车祸、地震、战争等外界因素)⑧adaptation/ˌædæp'teIʃn/n.变化；变种⑨as ...是as引导的时间状语从句，从句中含有两个who引导的定语从句，先行词分别是scientists和people, that ...是that引导的宾语从句。

Criticism from coaches, parents, and other teammates, as well as pressure to win can create too much anxiety or stress for young athletes. Stress can be physical, emotional, or psychological and research has indicated that it can lead to burnout. Burnout has been described as dropping or quitting of an activity that was at one time enjoyable.The early years of development are critical years forlearning about oneself. The sport setting is one where valuable experiences can take place. Young athletes can, for example, learn how to cooperate with others, make friends, and gain other social skills that will be used throughout their lives. Coaches and parents should be aware, at all times, that their feedback to youngsters can greatly affect their children. Youngsters may take their parents' and coaches' criticisms to heart and find fault with themselves.Coaches and parents should also be cautious that youth sport participation does not become work for children. The outcome of the game should not be more important than the process of learning the sport and other life lessons. In today's youth sport setting young athletes may be worrying more about who will win instead of enjoying themselves and the sport. Following a game many parents and coaches focus on the outcome and find fault with youngsters' performances. Positive support should be provided regardless of the outcome. Research indicates that positive support motivates (激发) and has a greater effect on learning than criticism. Again, criticism can create high levels of stress, which can lead to burnout.A．make sports less competitiveB．increase their sense of successC．reduce their mental stressD．make sports more challenging解析：选C 细节理解题。

Unit 21 Human BiologySection_ⅠWarmup & Lesson 1 —Prereading[原文呈现]100 metres in 8 seconds?Many contemporary①amateur athletes would have broken world records if they had taken part in② the first Olympic Games. Since then, records have fallen in track and field③ year after year④ as athletic performances have continually improved.If records fall, it is usually due to better equipment, training and diet, but recently, improvements have begun to slow down⑤. At the 2000 Olympics, only three runners achieved Olympic bests⑥with no worldrecords. Some experts predict a ceiling⑦for many events, such as 9.5 seconds for the 100 metres — Maurice Greene's current record is 9.79 seconds.However, past predictions have nearly always been proved wrong.When we talk about breaking records⑧，we come across the issue of performanceenhancing⑨ drugs. These drugs are originally developed to help people with illnesses⑩， but in the wrong hands⑪， they create supreme⑫ athletes making them faster and stronger than is normal for human beings. Taking these drugs⑬ is known as “doping⑭” and although they enhance performance, they also cause serious health problems⑮ in later life for those who abuse⑯ them.[读文清障]①contemporary adj.当代的，同时代的②这是一句表示与过去事实相反的虚拟语气。

To try to replicate (复制) something that is so poorly understood may therefore seem like pride. But you have to start somewhere, and International Business Machines (IBM) and the Ecole Polytechnique Federale deLausanne (EPFL), in Switzerland, propose to start by replicating“in silico”， one of the brain's building blocks.In a partnership announced, the two organizations said theywould be working together to build a simulation (模拟) of a structure known as a neocortical (新大脑皮质的) column on a type of IBM supercomputer that is currently used to study the molecular functioning of genes. If that works, they plan to use more powerful computers to link such simulated columns togetherinto something that mimics (模仿) a brain.In a real brain, a neocortical column is a cylindrical (圆柱形的) element about a third of a millimeter in diameter and three millimeters long. It is these columns, arranged side by side like the cells of a honeycomb, which make up the famous “grey matter” that has become shorthand for human intelligence. The Blue Gene/L supercomputer that will be used for the simulation consists of enough independent processors for each to be programmed to mimic an individual nerve cell in a column.The EPFL's contribution to the Blue Brain Project will be to create a digital description of how the columns behave. The database from its Brain Mind Institute will provide the raw material for the simulation. Biologists and computer scientists will then connect the artificial nerve cells up in a way that mimics nature. They will do so by assigning electrical properties (电能) to them, and telling them how to communicate with each other and how they should modify their connections with one another depending on their activity.That_will_be_no_mean_feat. Even a single nerve cell is complicated, not least because each one has about 10,000 connections with others. And nerve cells come in great variety —relying, for example, on different chemical transmitters to carry messages across those connections. Eventually, however, a digital representation of an entire column should occur.Assuming that the growth of computing power continues to follow Moore's Law, the leader of IBM's side thinks it should be practical to mimic an entire human brain in silico this way in ten to fifteen years. Such an artificial brain would, of course, be a powerful research tool. It would allow neurological experiments that currently take days in a “web lab” to be conducted in seconds. The researchers hope that their simulated brain will reveal the secrets of how certain psychiatric and neurological, disorders develop. But that is probably not the real reason for doing it. The most interesting question, surely, is whether such an artificial brain will be intelligent, or conscious, or both.语篇解读：对于人类来说，人脑是已知的最复杂的物体，也是科学无法解释的自然现象之一。

Unit 21 Human BiologyThe Olympic Games are not an annual event. According to the routine, it is held every four years.All athletes feel privileged to take part in the games. They come here not only to seek gold medals but also to challenge themselves. It's true that to win a gold medal means both a large fortune and a great fame.It goes without saying that every athlete aims to get the best results at all costs. However, some athletes turn to doping, which is absolutely prohibited. As is known to all, doping violates fundamental sports spirit and contradicts people's faith in fair play. So the act of doping cannot be tolerated, and if an athlete wants to achieve success by abusing drugs, his efforts will surely be in vain.So every athlete must obey all the rules unconditionally. In no circumstances should they violate them. And the best performanceenhancing way is not pills but systematic training and hard work.When it comes to winning in sports, teamwork is very important. Meanwhile, every athlete must have faith in himself or herself.Among all Olympic events, track and field events are most exciting and attractive, especially dash, which is a competition of speed. Marathon is also very attractive, which is a test of both physical strength and perseverance.奥运会不是一年一次的赛事。
