“Cleverness is a gift while kindness is a choice. Gifts are easy—they’re given after all. Choices can be hard. ”—Jeff Bezos.I got the idea to start Amazon in 1995. I came across the fact that the Internet usage was growing at 2, 300 percent per year. I’d never seen or heard of anything that grew that fast, and the idea of building an online bookstore with millions of titles was very exciting to me. I had just turned 30 years old, and I’d been married for a year. I told my wife MacKenzie that I wanted to quit my job and go to do this crazy thing that probably wouldn’t work since most start-ups don’t, and I wasn’t sure what to expect. MacKenzie told me I should go for it. As a young boy, I’d been a garage inventor.

Word文档，精心制作，可任意编辑Unit 2 CloningⅠ.阅读理解AThere are many ways in which human cloning is expected to benefit mankind.Below is a list that is far from completion.Dr.Richard Seed,one of the leading proponents (支持者) of human cloning technology,suggests that it may someday be possible to reverse the aging process because of what we learn from cloning.Scientists believe that they may be able to treat heart attack victims by cloning their healthy heart cells and injecting them into the areas of the heart that have been damaged.Heart disease is the number one killer in the United States and several other industrialized countries.There has been a breakthrough in the research on human stem cells.Embryonic (胚胎的) stem cells can be grown to produce organs to repair or replace damaged ones.Skin for burned victims,brain cells for the braindamaged,hearts,lungs,livers,and kidneys could be produced.By combining this technology with human cloning technology it may be possible to produce needed organs for suffering people that will be free of rejection by their immune systems.Conditions such as Alzheimer’s disease,Parkinson’sdisease,diabetes,heart failure,and other problems may be made curable if human cloning and its technology are not banned.Despite getting a fair amount of publicity in the news, current treatments for infertility (不生育),in terms of percentages,are not very successful.One estimate is that current infertility treatments are less than 10 percent successful.Couples go through physically and emotionally painful procedures for a small chance of having children.Many couples run out of time and money withoutsuccessfully having children.Human cloning could make it possible for more infertile couples to have children than ever before.1.The passage mainly deals with .A.the problems with human cloningB.the disadvantages of human cloningC.the advantages of human cloningD.the different ways human cloning is done2.According to Dr.Richard Seed we can use cloning technology .A.to make people look youngerB.to make people live longerC.to cure people of many diseasesD.to produce more animals3.From the passage we can infer that .A.cloning has already been used to treat heart diseasesB.we can treat a man’s heart disease by cloning others’ heartsC.most people in industrialized countries suffer from heart diseasesD.more people die of heart diseases than of other diseases in America4.What would be the best headline for the last paragraph?A.With Cloning,Infertile Couples Could Have ChildrenB.Treatment of Infertility Is Not SuccessfulC.Physically and Emotionally Pain of Infertile CouplesD.The News Is Not Telling the Truth5.With an organ cloned from his own stem cells, .A.the patient is more likely to develop other diseasesB.the patient’s immune systems don’t reject the new organC.the patient will be free of rejection by his immune systemsD.the patient will suffer from Alzheimer’s diseaseB(2018山东寿光现代中学高三开学考试,B)Seven years ago, back in 2010,some reports covered a story that the world’s longest railway tunnel was under construction in Switzerland. At that point it had already been under construction for over a decade. It had been voted to be built nearly a quarter of a century ago!

It even runs under an old tunnel that was there before. It took a total of 17 years to build at a cost of $12 billion.128 million tons of rock were dug. Two million truckloads of earth were removed!The tunnel connects northern and southern Europe. The opening of this runnel was such a big deal that the Germany’s leader, Chancellor Angela Merkel, France’s president, Francois Hollande, and Italy’s prime minister, Matteo Renzi, were all there to celebrate, as was Austria’s chancellor Christian Kern.It’s called the Gotthard Base Tunnel.Eventually,325 freight and passenger trains will go through the tunnel, relieving a lot of traffic on the roadways there and making it a more environmentally friendly option.

If you're making determination for a healthier new year, consider a gut makeover(肠道清理)．Changing your microbe community(微生物群)，however, may not be easy，and nobody knows how long it might take.That's because the ecosystem already established in your gut determines how it absorbs and processes nutrients.So if the microbe community in your gut has been shaped by a daily diet of hamburgers and pizza，for example，it won't respond as quickly to a healthy diet as a gut shaped by vegetables and fruits that has a more varied microbe community.“The nutritional value of food is influenced in part by the microbe community that encounters that food，” said Dr Jeffrey Gordon，the senior author of the new paper and director of the Center for Genome Science and Systems Biology at the Washington University School of Medicine in St.Louis.“Nutritional components of a healthy diet have to be viewed from the inside out，” he said，“not just the outside in.”One of the questions the study set out to answer was how individuals with different diets respond when they try to improve their eating habits.The scientists harvested gut bacteria from humans，transplanted them into mice bred under germfree conditions，and then fed the mice either Americanstyle or plantbased diets.The scientists then analyzed changes in the mice's microbe communities.Of interest，the scientists harvested the gut bacteria from people who followed sharply different diets.One group ate a fairly typical American diet，consuming about 3 000 calories a day，high in animal proteins with few fruits and vegetables.Some of their favorite foods were processed cheese and lunch meat.The other group consisted of people who were calorierestricted.They ate less than 1 800 calories a day and had carefully tracked what they ate for at least two years，sticking to a mostly plantbased diet and consuming far less animal protein than the other group，a third fewer carbohydrates(碳水化合物)and only half the fat.Thiscalorierestricted group，the researchers found，had a far richer and more diverse microbe community in the gut than those eating a typical American diet.They also carried several kinds of“good” bacteria，known to promote health，that are unique to their plantbased diet.“Perhaps the best way to shape a healthi er microbe community is to eat morefiber by consuming more fruit，vegetables，whole grains，and nuts or seeds，” said Meghan Jardine，a dietitian who was not involved in the current study but has published articles on promoting healthy microbe communities.She urges people to aim for 40 to 50 grams of fiber daily，well above levels recommended by most dietary guidelines.1．What can we know from the first two paragraphs?A．Changing microbiome is fairly easy.B．Ecosystem in gut is shaped by carbohydrates.C．Nutritional components are determined by food intake.D．As to healthy diets，microbe community shaped by vegetables and fruit respond more quickly than that shaped by junk food.2．What can we learn about Meghan Jardine?A．She suggests eating as little as possible.B．She attaches great importance to fiber.C．She is one of the researchers of the current study.D．She advocates consuming more meat in daily life.3．What's the author's attitude toward gut makeover?A．Concerned.

Unit 2 CloningⅠ.阅读理解(2017·9月浙江宁波十校联考)What is the nature of the scientific attitude,the attitude of the man or woman who studies and applies physics,biology,chemistry,geology,engineering,medicine or any other science?We all know that science plays an important role in our societies.However,many people believe that our progress depends on two different aspects of science.Thefirst aspect is the application of the machines,products and systems of knowledgethat scientists and technologists develop.The second is the application of the special methods of thought and action that scientists use in their work.What are these special methods of thinking and acting?First of all,it seems that a successful scientist is curious—he wants to find out how and why the universe works.He usually pays attention to problems which he notices have no satisfying explanation,and looks for relationships even if the data available seem to be unconnected.Moreover,he thinks he can improve the existing conditions and enjoys trying to solve the problems which this involves.He is a good observer,accurate,patient and objective and uses the facts he observes to the fullest.For example,trained observers obtain a very large amount of information about a star mainly from the accurate analysis of the simple lines that appear in a spectrum(光谱).He does not accept statements which are not based on the most complete evidence available.He rejects authority as the only basis for truth.Scientists always check statements and make experiments carefully and objectively.Furthermore,he does not readily accept his own idea,since he knows that man is the least reliable of scientific instruments and that a number of factors tend to disturb objective investigation.Lastly,he is full of imagination since he often has to look for relationships in data which are not only complex but also frequently incomplete.Furthermore,he needs imagination if he wants to guess how processes work and how events take place.These seem to be some of the ways in which a successful scientist or technologist thinks and acts.【语篇导读】本文是一篇说明文。

Unit 2 CloningⅠ.阅读理解AStaying silent can be just as powerful as the words you mean to say, like whenthe act of hugging will be more ####forting than saying, “Sorry for your loss.”Another time when silence is golden is when you are unsure of what to say. Ifyou are confused about your own feelings concerning a matter, it's best to stay quiet until you are more certain because more harm can be done by revealing falseor exaggerated feelings. Choose silence instead of blurting out “in–the–moment” feelin gs that are hurtful and not really how you feel in the grand scheme of things. When you feel the urge to say an unkind thing, take a few breaths and think of the possibleconsequences of your words. Silence can be your best friend during negotiations. Say your piece, then close your mouth, and let other persons ####e to their own conclusions. Your silence shows that one, you are confident in what you just said, and two, you respect other personsenough to hear what they have to say. Sometimes silence is the best and most timely solution because other personsare not in a position to hear what you have to say. For example, when a friend needs you to listen to her problems, but she is unable to accept your advice at that moment. Practice being silent at work when you don't have anything meaningful toelevatecontribute. Unless you canthe conversation by pointing out something interesting, missing, or beneficial, it's best to just observe and learn. Finally, silence is golden when you don't want to engage in a fool's argument.As some squabbles will never be resolved, one must agree to disagree. However, there will be times in your life when you will need the power of your voice, the voice within you that wants and needs to be respected and appreciated.语篇导读本文为议论文。

D．Nervous.4．Which is the best title for the text?A．Microbe community in our gutB．A gut makeover for the new yearC．Dietary guidelines for daily dietsD．The best way towards a healthier microbe community【解题导语】本文是一篇说明文。

Unit 2 Cloning李仕才一、阅读理解AEnjoying a musical performance no longer requires a costly ticket or a trip to a theater. These days, musicians are performing in private homes, at haircutting shops, at airports... even on ferry boats.Musicians like house concerts. At music clubs, they often have to perform over loud conversation or deal with people who have had too much alcohol. People at house concerts are more focused on listening to the music.Just a few hours before the Bombadils started singing at the O' Hair Salon, Lindsay was cutting hair and Tamera was doing facials. Then, they moved chairs and microphones to create a small performance space. The Bombadils made music in the front part of the hair salon, near the hairdryers and makeup tables.“This is our first show at a hair salon，” Sarah Frank of the Bombadils told concertgoers at last week's performance. Frank said she and band members, Luke Fraser and Kaitlyn Raitz had a great time “interacting” with the audience.Concerts in people's homes, or small businesses such as O' Hair's, are becoming more popular, musicians say. “There is a more relaxed atmosphere，” said Domenic Cicala, a musician who opened up his O' Hair Sal on to concerts. “People really get to know the artists.”At house concerts, people get time before and after concerts to meet the performers. Often, the hosts or guests will provide food and drink.“People really like listening to music in the living roo m of a friend，” said Matt Hart, with Aubrey Zoli making up the Local Strangers, a folkrock group based in Seattle. At many such concerts, the musicians do not need microphones. Yet, every word of their songs can be heard.【文章大意】本文主要介绍了现代音乐会在举办场地的选择上更加多样化。

课时作业37Ⅰ.阅读理解(2019·烟台一中高三适应性考试)China became the first country to clone a monkey using nonreproductive cells, reducing the need to breed lab monkeys and paving the way for more accurate, effective and affordable animal tests for new drugs, scientists said on Thursday.By December, the Institute of Neuroscience of the Chinese Academy of Sciences had created two clone macaques(猕猴) named“Zhong Zhong” and “Hua Hua” by nuclear transferring of somatic cells(体细胞)—any cell in the organism other than reproductive cells.Tetra, a monkey born in 1999, is the world's first cloned monkey, but it was done by using a simpler method called embryo splitting(胚胎分割); but it could only generate four cloned offspring at a time and cannot be genetically changed to suit the experimental need.Cloning a monkey using somatic cells has been a worldclass challenge because it is a primate(灵长类) that shares its genetic makeup, and therefore all of its complexity, with humans.For drug and other lab tests, scientists have to purchase monkeys from all over the world, which is costly and bad for the environment, and produces inaccurate results because each monkey might have different genes.By cloning monkey using somatic cells, we can massively cultivate large numbers of genetically identical offspring in a short amount of time, and we can even change their genes to suit our needs. This can save time, cut down experiment costs, and produce more accurate results, leading to more effective medicine.Sun Qiang, d irector of the nonhuman primate research facility at the institute, said most of the drug trials are currently done on lab mice. However, drugs that work on mice might not work or even have severe side effects on humans because the two species are so different.“Monkeys and humans are both primates, so they are much closely related and testing on monkeys is supposed to be as effective as testing on humans，”he said. This is especially useful in testing drugs for neural (神经的) diseases such as Parkinson's disease, metabolic syndrome (代谢综合征) and immune system diseases, and tumors, he added.“This achievement will help China lead the world research in the international science projects related to neural mapping of primate brains，”he said. “However, bio labs from the United States, Japan, and European countries are also very capable, and they will quickly catch up with China after the monkey cloning technology ismade public，” Sun added.“This means we have to innovate continuously and work extra hard this year to stay ahead，” he said.本文是一篇科普类说明文。
