Answers:①Athletes are stronger and faster today than they were during the time of the first Olympic Games.②Better equipment, training and diet.③Doping is using performance-enhancing drugs and it is illegal because it is cheating.④Ben Johnson was caught taking drugs when he broke the 100m world record in 1988 and no one knows if Florence Griffith was taking drugs when she set the women’s 100m record the same year.⑤Drug tests are only developed after the new drugs are being used. This means that there is a time period when people are using the new drugs and no one knows about them.⑥It would create super athletes who could do the 100m in just 8 seconds for example, and no one would know if they’d had gene-therapy or not. This would spoil the spirit of sport.⑦The spirit of competition that emphasizes talking part rather than winning.III. Language Points:1. slow down减速，放慢速度You must slow down your car. /你必须把车子开慢。

【高中】北师大版高中英语选修七Unit21HumanBiologyLesson3学案
【关键字】高中Epidemics throughout historyWith recent news reports connected Bird Flu with a killer epidemic in the past , Jim Smith looks through the history of epidemics for clues about what the future might hold.Bacteria and viruses have been around since the beginning of life on Earth and many of today’s diseases have existed as long as humans have. It is important to look at the spread of diseases throughout history to discover the causes and effects of epidemics , and hopefully , foresee and prevent them in the future, especially as scientists proved that Bird Flu is a modern adaptation of the same virus of the Spanish Flu.One of the earliest epidemics on record happened about 500-550 AD when the Roman emperor at the time was attempting to rebuild the Roman Empire . This epidemic ，which was called Justinian’s Plague , swept through North Africa , the Middle East and Europe. Scientists now guess that up to 50% of the area’s population died from this epidemic making it one of the main causes of the fall of the Roman Empire.In the 1330’s , the epidemic returned , this time in Asia . This spread rapidly and became known as “The Black Death ” as one symptom was black spots on the body . In urban areas all over Europe , Asia , Africa and the Middle East , up to one half of the population was lost to the Black Death .Another epidemic that spread in similar conditions was the Spanish Flu. It struck about 1918-1920 and left families mourning worldwide. Having killed up to 50 million people in 18 months , with a tendency to strike the young and fit rather than the old . More people died of the flu than died in the war .Yet , somehow , it was forgotten by history until very recently when SARS became a cause for concern . The SARS epidemic began in 2002 with a lung disease in Guangdong Province and spread quickly after Dr Liu Jianjun, the carrier , came to Hong Kong and passed the virus to people who carried it to Canada , Vietnam and Singapore.Over nine months , 8000 cases were reported in over 30 countries across five different continents and 774 people died . Although these statistics are much less impressive than those for the Spanish Flu , SARS was still very alarming for a few key reasons.Generally, SARS symptoms include a high fever, body aches, and headaches.However, as the illness progresses, most patients eventually develop pneumonia.The SARS virus spreads mainly by close human contact, either through the air or surface-touching.No one really knew much about SARS as it was completely new. This meant that there were no prescription drugs or tablets to treat it and doctors were not sure how to prevent it either.Since most people had no natural defences against the disease, it was also harmful to the doctors and nurses treating SARS patients.Since the SARS epidemic ended , scientists have been doing trials on treatments to prohibit any future outbreaks . Modern communication technology and medical research techniques allow health experts all over the world to unite , share knowledge , and work together without pause to help put SARS behind us.Meanwhile , governments worldwide have also underlined the fact that thorough and systematic medical research on Bird Flu needs to lead to a cure as soon as possible . Countries willneed to work together to do this as the SARS epidemic proved how teamwork among nations can save lives. With all the international effort being made, We have to have faith that there will be solutions in time to stop a Bird Flu epidemic in its tracks.Word Bankacute (adj.) ---severe (严重的), sharp （剧烈的）adaptation (n.)-----changecancer (n.)------a kind of disease which can always cause deathcarrier(n.) ----person or animal that can transmit(传染) a disease to others . epidemic(n.) ---disease spreading quickly among many people in the same place for a time, eg.

Opinions are divided.Some believe that human cloning is a good thing. Firstly, They think if people had too much work to do , they could get their own clone to help them. That wouldn’t be cheating because it would still be themselves doing the work. As a result, they would have so much time to rest and have fun. What’s more, human cloning could alsosolve the problem of finding the organs for organ transplants. Sothat it could help people lead longer and healthier lives.However, others are against it .They think human cloning is a terrible idea, which could cause a lot of problems. First of all, it could cause family confusion. If people were cloned , how could their clone fit into their family? Remember, their clone would be exactly like them. In addition, clone could cause problem for society. If everyone decided to be cloned there would be a population of explosion.In my opinion, I ’d prefer to have human cloning . In that case, we can clone people with special talents that would be helpful for social development.People are against the human cloning and the argument Paragraph 1Writer’s opinion about thetopic Paragraph 2People are for the human cloning and theargument Paragraph 3Introduction of thetopic Paragraph 4Task 2：Read the passage to fill in the formTask 3：find out topic sentences in each paragraph.Paragraph 1 Topic sentence________________________________________________________________1)______________________________________________________________2) _____________________________________________________________3)______________________________________________________________Opinions _____ whether we choose to be treated by Chinese traditional Medicine _____________________.（人们关于是否选择使用中药治疗的看法不同）。
