新概念英语85年上外美音版第四册第21课：Science Makes SenseLesson 21 Science Makes Sense 知识源于科学In the early days of the settlement of Australia, enterprising settlers unwisely introduced the European rabbit. This rabbit had no natural enemies in the Antipodes, so thatit multiplied with that promiscuous abandon characteristic of rabbits. It overran a whole continent. It caused devastationby burrowing and by devouring the herbage which might have maintained millions of sheep and cattle. Scientistsdiscovered that this particular variety of rabbit (and apparently no other animal) was susceptible to a fatal virus disease, myxomatosis. By infecting animals and letting them loose in the burrows, local epidemics of this disease couldbe created. Later it was found that there was a type of mosquito which acted as the carrier of this disease andpassed it on to the rabbits. So while the rest of the world was trying to get rid of mosquitoes, Australia wasencouraging this one. It effectively spread the disease all over the continent and drastically reduced the rabbit population. lt later became apparent that rabbits were developing a degree of resistance to this disease, so thatthe rabbit population was unlikely to be completely exterminated. There were hopes, however, that the problem of the rabbit would become manageable.Ironically, Europe, which had bequeathed the rabbit as a pest to Australia acquired this man-made disease as a pestilence. A French physician decided to get rid of the wildrabbits on his own estate and introduced myxomatosis. It did not, however, remain within the confines of his estate. It spread through France where wild rabbits are not generally regarded as a pest but as a sport and a useful food supply, and it spread to Britain where wild rabbits are regarded as a pest but where domesticated rabbits, equally susceptible to the disease, are the basis of a profitable fur industry. The question became one of whether Man could control the disease he had invented.。

关于科学实验发明的英语高考作文Scientific experiments and inventions have always been at the forefront of human progress, paving the way for technological advancements and improved quality of life. From the discovery of electricity to the invention of the internet, these scientific endeavors have revolutionized our world.This essay explores the significance of scientificexperiments and inventions, highlighting key historical examples, the process of scientific experimentation, and the impact of these inventions on society.Firstly, it is essential to understand the importance of scientific experiments and inventions. These activities arethe backbone of scientific progress, allowing us to explorethe unknown, solve complex problems, and develop new technologies. Scientific experiments provide a structured method for testing hypotheses, analyzing data, and drawingconclusions. They are fundamental to the scientific method, ensuring that new knowledge is based on empirical evidence and can be replicated and verified by others.One of the most notable examples of the significance of scientific experiments is the discovery of penicillin by Alexander Fleming in 1928. This discovery revolutionized the field of medicine, leading to the development of antibiotics, which have saved millions of lives by effectively treating bacterial infections. Fleming's experiment involved observing the antibacterial properties of mold, which eventually led to the isolation of penicillin. This breakthrough exemplifies how a simple scientific experiment can lead to an invention that transforms the world.Another significant invention resulting from scientific experimentation is the electric light bulb. Thomas Edison's meticulous experiments with different materials for the filament eventually led to the creation of a practical andlong-lasting light bulb in 1879. This invention not only illuminated homes and streets but also extended working hours and improved productivity, marking a significant milestone in the industrial revolution.The process of scientific experimentation involves several critical steps. It begins with the identification of a problem or a question that needs to be answered. Researchers then formulate a hypothesis, which is a tentative explanation or prediction that can be tested. The next step involves designing and conducting experiments to test the hypothesis. This includes selecting appropriate materials, methods, and controls to ensure the accuracy and reliability of the results. After conducting the experiments, researchers analyze the data, draw conclusions, and publish theirfindings for peer review and verification.One of the key aspects of scientific experimentation is the need for precision and rigor. Experiments must becarefully designed to minimize errors and biases. This often involves using control groups, randomization, and blinding techniques to ensure that the results are valid and reliable. Additionally, the repeatability of experiments is crucial. Other scientists should be able to replicate the experiments and obtain similar results to confirm the findings.The impact of scientific inventions on society cannot be overstated. They have fundamentally changed the way we live, work, and interact with the world. The invention of the telephone by Alexander Graham Bell in 1876, for example, revolutionized communication, making it possible to speak with someone across long distances instantly. This invention laid the groundwork for modern telecommunications, including mobile phones and the internet, which have become integral parts of our daily lives.Similarly, the invention of the airplane by the Wright brothers in 1903 transformed transportation, making itpossible to travel long distances quickly and efficiently. This invention has had profound economic, social, andcultural impacts, connecting people and places across the globe and facilitating international trade and tourism.In the field of information technology, the invention of the computer has had a monumental impact. The development of the first electronic computer, ENIAC, in 1945 by John Presper Eckert and John Mauchly, marked the beginning of the digital age. Computers have since become indispensable tools in various fields, including science, education, healthcare, and entertainment. They have enabled complex computations, data analysis, and simulations that were previously impossible, driving innovation and progress in countless areas.Furthermore, scientific inventions have also played a crucial role in addressing global challenges. For instance, the development of renewable energy technologies, such as solar panels and wind turbines, has provided sustainablealternatives to fossil fuels, helping to combat climatechange and reduce environmental pollution. These inventionsare the result of extensive scientific research and experimentation, highlighting the importance of continued investment in science and technology.In conclusion, scientific experiments and inventions are vital components of human progress. They provide thefoundation for new knowledge, technological advancements, and solutions to complex problems. Historical examples, such asthe discovery of penicillin, the invention of the light bulb, and the development of the computer, demonstrate the profound impact of scientific endeavors on society. The process of scientific experimentation, characterized by precision, rigor, and repeatability, ensures that new discoveries are reliable and can be built upon by future researchers. As we continueto face global challenges, the role of scientific experiments and inventions will remain crucial in driving innovation and improving the quality of life for people around the world.。

The first comprehensive study on the nation's oral health，released recently by the Office of the U.S. Surgeon General，calls dental and oral disea ses a “silent epidemic (流行病)，” even in children. The report states that more than 51 million school hours are lost each year to dental-related illness. In fact，a recent study pointed to dental care as the most common unmet health need among American children.To help counter this，the American Academy of Periodontology (牙周病学)(AAP)is launching an effort to educate children and parents about the prevention of dental diseases in children.“This is important because oral problems can impact self-esteem for children and lead to problems of eating，speaking and attending to learning，” said Michael McGuire，president of the AAP.Common dental problems seen in children are cavities (龋洞)and gingivitis (龈牙)，which are found in the majority of U.S. children. “When these pr oblems are not caught early and treated，they can develop into more severe problems and cause unnecessary suffering，” said McGuire “However，much of the time，oral problems are avoidable problems.”In the Rio Grande Valley in Texas，a group of more than 120 dentists volunteers to deliver dental care to thousands of low-income children each year with its Mobile Dental Unit that travels from school to school.“According to the Surgeon General's Report，about 37 percent of children have not had a dental visit before starting school，” said McGuire. “When children don't see dentists theymiss the opportunity to have problems caught early before they develop into larger，more expensive problems to treat，and parents miss the opportunity to learn how to promote good oral habits in their children.”16 Only in February should attention be paid to children's oral healthA RightB WrongC Not mentioned17 Dental and oral diseases are common in both adults and childrenA RightB WrongC Not mentioned18 Boys miss more school hours each year due to dental-related illnessA RightB WrongC Not mentioned19 Oral problems in children can develop into more severe problems.A RightB WrongC Not mentioned20 Oral problems can not be avoided in any wayA RightB WrongC Not mentioned21 The low-income children are very grateful to the dentists.A RightB WrongC Not mentioned22 Some children have never seen a dentist before starting school.A RightB WrongC Not mentioned第3部分：概括大意与完成句子(第23～30题，每题1分，共8分)下面的短文后有2项测试任务：(1)第23～26题要求从所给的6个选项中为第1～4段每段1选择个最佳标题;(2)第27～30题要求从所给的6个选项中为每个句子确定1个最佳选项。

科学小制作或小发明英文回答：Science is a fascinating field that constantly pushes the boundaries of human knowledge and understanding. Throughout history, scientists have made numerous small inventions and creations that have had a significant impact on our daily lives. In this response, I will share two examples of small inventions or creations in the field of science.One interesting small invention is the Post-it Note. This simple yet ingenious creation was developed by a scientist named Spencer Silver. He was trying to create a super strong adhesive, but instead, he accidentally created a weak adhesive that could stick to surfaces but could also be easily removed without leaving any residue. It wasn't until his colleague, Arthur Fry, came up with the idea of using the adhesive to create sticky notes that the Post-it Note was born. Today, Post-it Notes are widely used fortaking quick notes, leaving reminders, and organizing information.Another small invention that has had a big impact isthe ballpoint pen. Before the ballpoint pen was invented, people used fountain pens, which required constantrefilling and were prone to leaking and smudging. In the 1930s, a Hungarian-Argentinian journalist named LászlóBíró came up with the idea of using a tiny ball bearingin the pen's tip to control the flow of ink. Thisinnovation allowed for a smooth and consistent writing experience without the need for constant ink refills. The ballpoint pen revolutionized the way people write and isstill widely used today.中文回答：科学是一个令人着迷的领域，不断推动人类知识和理解的边界。
