英语基础模块上册unit9cultivation全文共3篇示例，供读者参考篇1Title: CultivationUnit 9 in the English Basic Module focuses on cultivation, which is the process of preparing the soil, planting seeds, and caring for plants in order to promote growth and development. Cultivation is essential for agriculture, horticulture, and gardening, as well as for fostering personal growth and development.The Importance of Cultivation:Cultivation plays a vital role in food production, as well as in the beautification of landscapes. Without cultivation, crops would not grow properly, and gardens would not flourish. In addition to providing sustenance and aesthetic value, cultivation has numerous benefits for individuals and communities. It promotes physical activity, mental well-being, and a sense of accomplishment. Cultivation also fosters environmental stewardship, as it encourages responsible land management and sustainable practices.The Process of Cultivation:The process of cultivation involves several key steps, including preparing the soil, selecting seeds or plants, planting them, watering and feeding them, and protecting them from pests and diseases. Each step is important for ensuring the success of the cultivation process. Proper soil preparation, for example, helps plants establish strong roots, while regular watering and feeding supply them with essential nutrients. Pesticides and fungicides can be used to control pests and diseases that may threaten the health of plants.Cultivating Personal Growth:Cultivation is not only important for plants but also for individuals. Cultivating personal growth involves nurturing one's talents, skills, and potential in order to reach one's full potential. This process requires dedication, patience, and hard work, just like cultivating plants. By setting goals, developing new habits, and seeking out opportunities for growth, individuals can cultivate their personal development and achieve success in various areas of their lives.Cultivation in Education:Cultivation is also a key concept in education, where it refers to the process of nurturing students' intellect, skills, and character. Educators cultivate their students by providing them with the knowledge, resources, and support they need to succeed. By creating a positive learning environment, setting high expectations, and fostering a growth mindset, teachers can cultivate their students' academic and personal growth. Cultivation in education also involves promoting moral values, social skills, and emotional intelligence in students.In conclusion, cultivation is a fundamental process that plays a crucial role in agriculture, horticulture, gardening, and personal development. By understanding the importance of cultivation, mastering the process, and applying it to various aspects of life, individuals can grow and thrive in both their personal and professional endeavors. Cultivation is a journey of growth, transformation, and self-discovery that requires patience, dedication, and resilience. As we cultivate our gardens and ourselves, we become more connected to nature, to others, and to ourselves. Let us embrace the process of cultivation as a pathway to growth, fulfillment, and success.篇2Unit 9 CultivationIn Unit 9 of the English basic module, students will learn about cultivation, which is the process of preparing and tending to the soil in order to grow crops or plants. Cultivation is an essential part of agriculture and is crucial for providing food for the world's population. In this unit, students will learn about different cultivation techniques, tools, and practices.1. Types of Cultivation:- Traditional Cultivation: This method involves manually preparing the soil using tools such as hoes and shovels. Traditional cultivation is labor-intensive but is still widely practiced in many developing countries.- Mechanized Cultivation: This method uses machines such as tractors and plows to prepare the soil. Mechanized cultivation is more efficient and allows for larger areas of land to be cultivated in a shorter amount of time.- Organic Cultivation: This method involves growing crops without the use of synthetic chemicals or pesticides. Organic cultivation is becoming increasingly popular due to its environmental benefits and health benefits for consumers.2. Cultivation Tools:- Plow: A plow is a farming tool used to break up and turn over soil in preparation for planting. There are different types of plows, including the moldboard plow and the disc plow.- Hoe: A hoe is a gardening tool used to remove weeds and cultivate the soil. There are different types of hoes, including the Dutch hoe and the draw hoe.- Tractor: A tractor is a farming vehicle used to pull heavy machinery such as plows and seeders. Tractors are essential for mechanized cultivation.3. Cultivation Practices:- Crop Rotation: Crop rotation is the practice of planting different crops in the same field in succession. This helps to maintain soil fertility and prevent soil erosion.- Mulching: Mulching is the practice of covering the soil with materials such as straw or bark to retain moisture and suppress weeds. Mulching also helps to improve soil structure.- Irrigation: Irrigation is the process of supplying water to crops to ensure proper growth and yield. There are different irrigation methods, including drip irrigation and sprinkler irrigation.In conclusion, cultivation is a fundamental aspect of agriculture and plays a crucial role in feeding the world's population. By learning about different cultivation techniques, tools, and practices in Unit 9, students will gain a deeper understanding of how food is produced and the importance of sustainable farming practices.篇3Unit 9 Cultivation in the Basic English module focuses on various aspects of cultivation, including agriculture, gardening, and the development of skills and knowledge. In this unit, students will learn key vocabulary related to cultivation, practice their listening and speaking skills through discussions androle-plays, and engage in reading and writing activities to deepen their understanding of the topic.One of the key topics covered in this unit is agriculture. Agriculture is the practice of cultivating crops and raising animals for food, fiber, and other products. Students will learn about different types of agriculture, such as subsistence farming, commercial farming, and organic farming. They will also learn about the importance of sustainable agriculture practices in preserving the environment and ensuring food security for future generations.Another important topic covered in this unit is gardening.

Ambition研究生综合英语unit 9 PPT

Unit Nine AmbitionI. Introduction of the authorPerri Klass, MD, is a pediatrician and writer, who has published extensively about her medical training and pediatric practice. She is well known for her writing about the issues of women in medicine, about relationships between doctors and patients, and about children and literacy. She is the author of both fiction and nonfiction: novels, stories, essays, and journalism.Dr. Klass is Professor of Journalism and Pediatrics at New York University, and Medical Director of Reach Out and Read, a national childhood literacy program that works through doctors and nurses to encourage parents to read aloud to young children, and to give them the books they need to do it.She is a member of the National Advisory Council of the National Institute of Child Health and Human Development, and has been nominated by the President of the United States to the Advisory Board of the National Institute For Literacy.Baruch de SpinozaBaruch de Spinoza was a Jewish-Dutch philosopher. Revealing considerable scientific aptitude, the br eadth and importance of Spinoza’s work was not fully realized until years after his death. By laying the groundwork for the 18th century and modern biblical criticism, he came to be considered one of the great rationalists of 17th-century philosophy. His magnum opus, the posthumous Ethics, in which he opposed Descartes’s mind–body dualism, has earned him recognition as one of Western philosophy’s most important contributors. In the Ethics, ―Spinoza wrote the last indisputable Latin masterpiece, and one in which the refined conceptions of medieval philosophy are finally turned against the mselves and destroyed entirely.‖Philosopher Georg Wilhelm Friedrich Hegel said of all contemporary philosophers, ―You are either a Spinozi st or not a philosopher at all.‖Jane Goodall is a British primatologist, ethologist, anthropologist, and UN Messenger of Peace. Considered to be the world's foremost expert on chimpanzees, Goodall is best known for her 45-year study of social and familyinteractions of wild chimpanzees in Gombe Stream National Park, Tanzania. She is the founder of the Jane Goodall Institute and has worked extensively on conservation and animal welfare issues.II. The theme of the textDr. Klass discusses he r understanding of ambition and its meaning to one’s life. According to her, ambition is dreaming big dreams with no restrictions on one’s expectations. Ambition may make one frustrated or even one-sided, but it can also drive you to get close to your drea m which deserves to be cherished in one’s life.III. Structure of the textPart I Introduction (Para. 1-3)Main idea: I appreciate ambitious people since they have grandiose dreams and are entertaining and interesting to talk to. I am also an ambitiouspeople and do not feel apologetic about it.Part II Main body (Para. 4-14)∙Main idea: To some people, the word ―ambition‖ often relates with the words ―madness‖ and ―ruthless‖. However, in the late 70s and 80s, ―ambition‖ became desirable. But for me, ambitions are not some specific and attainable goals but big dreams. It is quite important but also difficult for one to live with his or her ambition.Argument 1 (para. 4-7)∙ Observing from a historical perspective, ambition has been a pejorative word. However, the author has her own understanding on this word.Example 1: the word ―ambitious‖ linked to a ―career woman‖ who is ruthless.Example 2: ―ambitious‖ is still a nasty attribute even it is favored by the ones who want to be successful.Argument 2 (para. 8-13)∙ People with or without ambition are tortured by ambition.Example 1: Achievements made by ambitious people will give you a great pressure.Example 2: One has to suffer a long time tough work to enjoy their delayed gratification.Example 3: One’s ambitions may come into conflict so one has to give up some of them.Part III Conclusion (Para 14-15)∙ Main idea: Although people are often over consumed by their ambitions, it is still necessary to cherish their own dreams which can drive you move forward.IV. Words and phrases1. grandiose: impressive because of unnecessary largeness or grandeur1) The sad truth is that not one of Tim's grandiose plans has even begun.2) Today it is the wealthiest enclave in the country, with gaudy, grandiosemansions that cost hundreds of thousands of dollars.如今它是这个国家最富裕的地区，拥有价值数十万美元，华丽而宏伟的高楼大宅。

Unit9End-of-lifecare临终关怀——《21世纪研究生英语教材阅读教程》下册.doc

Unit 9 End-of-life care临终关怀Into the sunset桑榆迟暮The idea that the terminally ill need pain relief and humane care instead of 'curing' is catching on. But what about the people who just grow old?1 绝症患者所需要的不是“治疗”，而是减轻痛苦和人道关怀，这一点正逐步得到认同。

但对那些走向死亡的老者又应如何？'MOST things may never happen: this one will.' That stark allusion to death, penned by the poet Philip Larkin, sums up the philosophical starting-point of the hospice movement, which began in Britain 40 years ago and has since become influential, in various ways, in almost every corner of the world. Given that your time on earth is bound to finish one day, assuring a decent quality of life in the final months and years often makes better sense than trying to prolong a painful existence for a short period; so in many cases, loving care and pain relief should take priority over aggressive intervention. When Dame Cicely Saunders, who founded the Saint Christopher's Hospice in London in 1967, first aired those ideas, the medical world was hostile. Now her beliefs enjoy wide acceptance.2 “世间事多数未必发生，唯有这一桩必定发生。

All heart.(Meaning: with the deepest devotion)PartⅡExercise A.Keys:4 35 2 4 1 3 4 4 1Tapescript:Our body is made up of thousands of different parts. All these parts work together to keep us alive and to help us move around. The parts of the human body are like the parts of a very complicated machine. Like any other machine, however, if it is inexpertly cared for, over-taxed or insufficiently used, it will become rusty, sluggish or clogged and parts of its mechanism may even grind to a halt. That is why it is so important to keep every part of the human machine healthy and properly cared. To keep in good running order, the body requires the raw materials for growth and the replacement of tissues when necessary. Our bodies bum food like fuel to produce the energy we need.The human digestive system is a bit like a very long tube, but it's a lot more complex. It's several meters long, and most of it is carefully coiled up in our abdomen. It has several important jobs to do.First, it must digest or break down our food. Digestion starts the moment food enters our mouth. Then it continues as the food is squeezed along the gut by muscles in the wall of the intestine. As the food travels through the gut, natural chemicals called enzymes are added to it, which help break down the food. Then this digested food and water must be absorbed from the gut into our blood stream so that it can be used by the body. Finally, the gut must carry away any waste products in the form of feces.Usually our intestine does all these things very efficiently. But sometimes things can go wrong. Probably the most common gut symptoms are diarrhea and constipation.With diarrhea, the food and water travels too quickly through the intestine, often making the feces watery, and making it necessary to open the bowels more frequently.There are lots of causes of diarrhea. Probably the commonest causes of diarrhea are contaminated food or water, and infection caused by viruses or parasites.Many cases of diarrhea clear up within a few days without any special medicines. But the body loses a lot of fluid through diarrhea, so there is a very real risk of the body drying out or becoming dehydrated. Because of this risk of dehydration, the best treatment for diarrhea is simply to make sure you are dinking enough. Avoiding dehydration in this way can be a life saver.Exercise B.Keys:Causes of diarrhea:food poisoning, themselves, the gut,get very nervous, stressed about something diarrheaTreatment of diarrhea:serious, clear up, one or two days, drink lots of fluid, eat too much, salt and sugar, specially mixed, sugar and a pinch of saltTapescript:There are lots of different causes of diarrhea. Um, there are infections that can happen, and this is food poisoning, if you like, where in your food you eat some sort of bacteria or organisms, which infect you. Some foods can just irritate thegut and tend to give you diarrhea, although they are not infected. It's just the food itself (that) might irritate your system. Some people, if they get very nervous and stressed about something, find they tend to get diarrhea. Something called the irritable bowel syndrome where something goes wrong with the way the gut works. And people that suffer from this tend to get, um, tummy pains, and they get sometimes diarrhea, sometimes constipation. All sorts of causes.Most attacks of diarrhea, urn, particularly in adults, are not serious and they clear up by themselves within one or two days. The most important thing is to drink lots of fluid, because if you have got diarrhea, you're obviously losing a lot of fluid. And so it's better really not to eat too much, not to worry about that, but o make sure you drink plenty of fluid. And ideally, this should have a little bit of salt and sugar in. You can get special dehydrating fluids, which are specially mixed. But if you want to make your own by adding just a teaspoonful of sugar and a pinch of salt, then it's obviously perfectly reasonable to do that.Part Ⅲ ImmunityExercise B.Keys:1. Because there are some things which we’re not naturally immune to.2. A version of an illness is given to the body, and the body thinks that it’s actually being infected with that infection. The next time it sees it, the body can respond very quickly.3. No. We can’t produce a vaccine for AIDS, for instance.4. The HIV virus, which causes AIDS, attacks the human immune system. And the virus itself can change very easily. It’s very difficult to find a vaccine which can recognize all types of HIV.Tapescript:The human body is constantly under attack from invading germs and infections. And the only reason we don't suffer from constant illness is our bodies have their own defense mechanism to fight off disease. This resistance to infection is called immunity.A: How does immunity workB: Well, the immune system is the body's own secret army, which fights infection.And it consists of a whole range of troops, soldiers, their cells and their molecules. Now the headquarters of this army is really the blood. That's where it does most of its fighting. And sometimes it needs some reserve, and that comes from the bone marrow. That's where the immune cells are made.A: So there are many different kinds of cells, different kinds of molecules in the immune system. I guessed the ones that we're probably more familiar with are white blood cells.B: That's right. White blood cells form a major part of the body's defense. But there are also antibodies in their life, more proteins. They just lash onto the invaders.The white cells can sometimes actually gobble up invaders. The clever thing is that once the infection has attacked our body, the immune system seems to havea memory of the invader, so that the next time it sees the invader it can attackvery quickly.A: There are some things which we're not naturally immune to and that's where vaccination comes in, isn't itB: Exactly. Vaccination plays on the body's ability to remember infection. So what happens is that someone is given a version of an illness, for instance, measles or polio, or tuberculosis, and the body thinks that it is actually being infected with that infection. And the next time it sees it, the body can respond very quickly. All the troops of its immune system can come into play.A: Now sometimes the immune system doesn't work very well, does itB: No. It's a remarkably complex system. And sometimes it can go wrong. Either it can be overactive, so it actually starts to attack our own body self, or it can be underachieve sometimes, and we are more likely to be infected in that situation.A: Are there any important illnesses, which result from the immune system so that it's turning on our bodies themselvesB: There are. One example would be a disease like multiple-sclerosis, where the body's own immune system attacks the lining of nerves, which means that people's nerves don't work properly.A: We're able to assist the body in its fight against the illness in many cases, but there are some diseases which we don't seem to be able to produce a vaccine for. AIDS is one of them. Why notB: The problem is AIDS, which is caused by the HIV virus, attacks the human immune system, which means that our normal defenses aren't there to fight off that infection. The other problem with trying to produce a vaccine against HIV or AIDS is that the virus, HIV, can change itself so easily. That's very difficult to find a vaccine, which can recognize all the different types of HIV. So one vaccine may be effective against one type of the virus but it may absolutely be no good for another type.Exercise C.Keys:headquarters → bloodGobbling up invadersHaving a memory of invadersUnderactive — more likely to be infectedthe immune system: 2 3vaccination: 5HIV: 1 4 6Tapescript:Presenter: The human body is constantly under attack from invading germs and infections. And the only reason we don't suffer from constant illness isour bodies have their own defense mechanism to fight off disease. Thisresistance to infection is called immunity. And here with me to discusshow it works is Grime Easton. He is a family doctor, and a member of theScience In It here in the BBC World Service. Grime, how does immunity work Grime: Well, the immune system is the body's own secret army, if you like, which fights infection. And it consists of a whole range of troops, soldiers, their cells and their molecules. Um, now the headquarters of this army is really the blood. That's where it does most of the fighting. And sometimes it needs some reserve, some backup, and that comes from the bone marrow. That's where the immune cells' factories are,Presenter: So there are many different kinds of cells, and different kinds of molecules tied up in the immune system. I guessed the ones that we'reprobably more familiar with are white blood cells.Grime: That's right. White blood cells form a major part of the body's defense. But there are also antibodies in their life, more proteins, which just lash onto the invaders. Um, but, as you say, the white cells can sometimes actually gobble up invaders. So the clever thing is that once the infection has attacked our body, the immune system seems to have a memory of the invader, so that the next time it sees the invader it can attack very quickly. The immune system in the human body fights invading disease. Immunity occurs because the immune system can remember the chemical makeup of invading germs and attack themvery quickly.Presenter: There are some things which we're not naturally immune to and that's where vaccination comes in, isn't itGrime: Exactly. Vaccination plays on the body's ability to remember infection. So what happens is that someone is given a version of an illness, for instance, measles or polio, or tuberculosis, and the body thinks that it is actually being infected with that infection. And the next time it sees it, urn, the body can respond very quickly. And all the troops of its immune system can come into play.Vaccination can be used to protect the body against specific infections. Presenter: Now sometimes the immune system doesn't work very well, does it Grime: No. It's a remarkably complex system. It's a very complicated system. And sometimes it can go wrong. Either it can be overactive, so it actually starts to attack our own body self, or it can be under active sometimes, and we are more likely to be infected in that situation.Presenter: Are there any important illnesses, which result from the immune system so that it's turning on our bodies themselvesGrime: There are. And one example would be a disease like multiple-sclerosis, where the body's own immune system, we think, attacks the lining of nerves, which means that people's nerves don't work properly.Presenter: We're able to assist the body in its fight against the illness in many cases, but there are some diseases which we don't seem to be able to producea vaccine for. Um, AIDS is one of them. Why notGrime: Well, the problem is AIDS, which is caused by the HIV virus, is that HIV itself attacks the human immune system, which means that our normal defenses aren't there to fight off that infection, or indeed many other sorts of infection.The other problem with trying to produce a vaccine against HIV or AIDS isthat the virus, HIV, can change itself so easily. Urn, that's very difficult to find a vaccine which can recognize all the different types of HIV, which there are. So one vaccine may be effective against one type of the virus but it may absolutely be no good for another type.HIV is the virus that causes AIDS. HIV destroys the body's immune system, and puts the body at greater risk from other common infections.Presenter: I was talking to Dr. Grime Easton of the Science In It about immunity.The reason why he, I, and I hope you, are able to remain as healthy as we are.Part Ⅳ The Circulatory SystemKeys:parts, waste, body, needed, heart, defense, cells, invaderstwo, lungs, blood, back, arterieswalls, cell, heart, oxygen, blood, digestive, liver, heartPartⅤHairKeys:Caller’s name: Jim BaillieProblem: losing hairCaller’s doctor’s opinion: nothing he can do about it; hereditarySolution: not a lot he can do about it; try to acceptAdvice: don’t comb it over; don’t wear any false hairpiece thingsTapescript:Radio presenter: All right.

What's your problemJim: Er ... well I'm er ... beginning to lose my hair. Er, I went to the doctor, but he just said there was nothing I can do about it. He said it was probably hereditary. My father was bald by the time he was thirty.Maurice: Hello, Jim. And how old are youJim: Me. I'm twenty-eight.Maurice: And are you losing a lot of hair, thenJim: Well, it comes out a lot when I comb my hair and you can see a thin part on the top of my head.Maurice: And does that really worry you, JimJim: Well. I don't like it. It's old ... you know ... looks old ... I don't want to look like a middle-aged man at twenty-eight. And I wondered if there was some special shampoo I should use ... if you could tell me one that I should buy ...something like that ... you know ... to stop it getting worse.Maurice: Well, you know, Jim, to be honest with you there's not really a lot you can do about it, actually, I'm afraid. I mean, baldness is one of those things that, in my experience, you just have to try to accept. Some men find it more difficult to accept baldness than others ...Tessa: There is one piece of advice, though, Jim, and that's don't try to comb your hair over the bald or thin patch. Don't try to hide it. Whatever you do, don't comb it over because that usually looks ridiculous. And the other thing that usually looks ridiculous g a man with a wig. Don't let anyone persuade you to buy one of those false hairpiece things, because they usually look much worse than a bald man. I actually think bald men can look very attractive.My husband's bald and I think it really suits him.。

Hello Ye, Ma Ye)
Sorry, it has been a bad week. Anyway
The medical system in the US has some variability to it. Generally speaking however, after you graduate high school you go to college for 4 years. You can major in many subjects such as Biology, Chemistry or even Math. There is no such thing as a Premedicine major for the most part. This gives doctors a more general education here. After college you would go on to apply and attend medical school. You only major in Medicine and there is no specialization in Medical School.

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 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 serve epidemic in human history. The 1997 bird flu which claimed over 100 lives was an adaptation of the Great Flu of 1918.
