(文章的)段，段落adj.相应的；对应的An epidemic is the rapid spread of an infectious disease over a short period of time，causing a large number of deaths， the number of which differs for different diseases.Professor Jim Smith conducted a study to compare the bird flu epidemic which occurred in 1997 with other deadly epidemics in our history. He found that the earliest epidemics took place as early as 500 to 550 CE，which killed half of the population in that particular area. The same epidemic，called “The Black Death”returned in the 1330s in Asia and spread quickly to Europe. Some hundred years later，the Great Flu epidemic broke out in 1918，also known as the Spanish Flu，killing 50 million people，This was considered the most severe epidemic in human history. The 1997 bird flu which claimed over 100 lives was an adaptation of the Great Flu of 1918.At the start of the 21st century，there were two major epidemics: SARS and EVD. The more recently discovered SARS disease infected about 8,000 people. According to official records EVD has killed more than 11,310 people in West Africa alone.Globally，researchers are coming together to try to identify the causes for epidemics and help to find effective treatments.vt. 确定，发现；认出，识别FOCUS ON STRUCTURE AND LANGUAGE 注重结构和语言1 1 Definition2 2—3 Successful examples on cloning3 4—6 Praise and concerns on cloningCloning is the process of making an exact copy of a plant or animal and developing it either naturally or artificially. Natural cloning has been going on for generations. For example，gardeners have been using a form of cloning when they take a cutting from a plant and place it in a suitable medium，such as soil. Another example of natural cloning is identical twins，who are produced from the same egg.______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________Key words： cloning，making an exact copy，plant or animal，natural cloning，going on for generationsSummary：Cloning means to make an exact copy of a plant or animal and natural cloning has been going on for generations.COMPOSE YOUR WRITING 撰写您的文章ANIMAL EXPERIMENTSVIEWING WORKSHOPWhat do you know about using animals in medical research?

It has developed a unique combination of treatments related to helping well-being and the prevention and treatment of diseases.BeliefPractitioners2(n.从业者(尤指医生或律师)) of TCM believe there is no separation between body and mind. They look at the interactions between mind，body and environment. The ancient beliefs include the following：·The human body is a miniature3(adj. 很小的，微型的) version of the larger，surrounding universe.·Harmony between two opposing yet complementary forces， called yin and yang，supports health，and disease results from an imbalance between these forces.·Five elements-metal，wood，water，fire and earth-symbolically represent all phenomena，including the stages of human life，and explain the functioning of the body and how it changes during an illness or disease.·Qi，a vital energy that flows through the body，performs multiple functions in maintaining health.adv. 象征地，象征性地TreatmentsTCM treatments aim to cure problems by restoring the balance of energies. Herbal medicine and acupuncture4(n.针刺(疗法)) are the most popular treatments. There are over 10,000 ingredients used in Chinese herbal medicine. Different parts of plants and their extracts are the most commonly used ingredients，although some animal and mineral ingredients are also used.n. 矿物质；矿产Acupuncture is a treatment that stimulates specific points on the body by inserting extremely thin needles into the skin. It is often used to provide pain relief for conditions like lower back pain， shoulder stiffness5(n. 僵直，酸痛)，and knee soreness. Other practices include breathing and movement exercises，massage therapy，and diet.n. 针GENERAL UNDERSTANDING 一般性谅解CRITICAL THINKING 批判性思维READING CLUB 2DNA DETECTIVESDNA detectives can be used to identify genetic1(adj. 基因的) information in order to detect disease. But with the development of technology，the DNA detective has been used in other aspects. For example，DNA detectives can figure out a person′s identity and how people were related.Nowadays，DNA detectives can help policemen catch criminals. It has been one of the key weapons for unsolved cases. The DNA is stored in a database，where policemen can find the same or similar DNA to track down suspects and victims.n.数据库，资料库n.数据库，资料库n. (袭击事件、抢劫事件或凶杀案的) 受害者A 17-year-old girl，Melanie Road，was on her way home alone at night in Bath (UK) on 8 June，1984. Her body was found the next day in a pool of blood.Police questioned several suspects，but they couldn′t identify the person who killed the girl. From Melanie′s body，the police have found a full DNA profile of the killer. They worked through a database of 12,000 male names who were either witnesses or suspects at the time；but no match was found.After 30 years，the criminal had still not been found. Melanie′s mother wrote to a local newspaper：“I know it′s a long time ago－to me it′s only yesterday. Some people say ... let it rest，but I can′t.”In 2014，a woman was arrested for a minor incident and her DNA was profiled. in July 2015，a match was found between her DNA and the DNA of Melanie′s killer. The police found the woman was the daughter of the killer，Christopher Hampton. The criminal was finally found 31 years later.Copernicus′ Grave FoundCopernicus2(哥白尼)，the Polish astronomer who died nearly 500 years ago，was identified by DNA evidence in the 21st century.In 2005，a skull3(n.头盖骨) and an incomplete skeleton4(n.骨架) were found in Frombork，Poland，where Copernicus was buried on 24 May，1543.n.天文学家The skull was used for identification and experts found that it had belonged to a 70-year-old man with a broken nose and a cut above his left eye.Copernicus died at seventy，had a broken nose as a result of a childhood accident and in a self-portraits5(n. 自画像) painted himself with a scar above the left eye. Experts were able to reconstruct the man′s face and it matched Copernicus′ portraits.However，they had to perform DNA tests to confirm the identity of the skull′s owner. They couldn′t easily find genetic material from Copernicus′ close relatives，but they were able to find a book he had owned for decades at Uppsala University. They didn′t have to look long to find nine hairs within the pages，some with good DNA samples. The DNA from the hair was the same as that from the bones found at Frombork. Interestingly, the analysis revealed that Copernicus probably had blue eyes，although he usually has dark eyes in his portraits.Some scientists say the team should not have announced their findings so early-they should have looked more carefully for the DNA from Copernicus′ mother or her relatives to check the results，as it is the mother′s DNA that is passed on intact6(adj. 完整的，不受损的) to her child.Despite these controversies，the great astronomer was officially buried again on 22 May，2010 in Frombork，The search for his mother′s DNA still continues.GENERAL UNDERSTANDING 一般性谅解1 What were the difficulties faced in each of the two cases?2 What have DNA detectives helped to find?CRITICAL THINKING 批判性思维
