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 plant­ba sed 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 werecalorie­restricted.They ate less than 1 800 calories a day and had carefully tr acked 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.This calorie­restricted 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 healthier microbe community is to eat more fiber 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. B．Opposed.C．Indifferent. 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。

The Internet plays a big part in human life. We use it for work and entertainment. We can find new recipes on the Internet or advice on staying healthy. We can even use it to learn a new language. We use the Internet to connect with family and friends and stay in touch with issues we care about.The list goes on and on.As far as the Internet being a part of our lives—well, that train has left the station. That expression means there is no going back. If you prefer boating, you can say that ship has sailed.So, there may be no going back to an Internet-free life. But can using the Internet too much be bad for our health?It might be, say researchers.Study results show that teens who spend at least 14 hours a week online were more likely to have high blood pressure.High blood pressure makes your heart and blood vessels work too hard. Over time, this extra strain increases your risk of a heart attack or stroke.High blood pressure can also cause heart and kidney disease. It is also closely linked to some forms of dementia, a brain disease. Dementia is marked by memory disorders, personality changes, and a reduced ability to reason.Let’s introduce something about the study of it.The Henry Ford Hospital in Detroit, Michigan did the study. It involved 335 young people, from 14 to 17 years old. One hundred thirty-four of the teens were described as “heavy Internet users”. Researchers found that out of these 134 teens, 26 had high blood pressure.The researchers say the study is the first to connect heavy web use and high blood pressure. Other research has connected that heavy Internet use with health problems including anxiety, depression and obesity.The lead researcher of the study is Andrea Cassidy-Bushrow. In a statement shes aid, “Using the Internet is part of our daily life but it shouldn’t consume us. ”For the purpose of the study, she explains, teens considered heavy Internet users were online on “average 25 hours a week. ”Ms Cassidy-Bushrow adds that it is important for teens to take “regular breaks from their computers or smartphones” and to do some “kind of physical activity. ”She also suggests that parents limit their children’s use of the Internet to two hours a day, five days a week.【文章大意】互联网如此有用并且融入我们的生活, 但过度使用它, 会导致多种健康问题。

Kanda really doesn’t like to walk alone.The scientist from a research institute of intelligent robots finds the experience so boring that he’d rather drive—even though he lives close to his lab and knows that walking is healthy.“I enjoy walking with someone，like with my wife，with my daughter，” Kanda said.“But they are not always available.”So Kanda，who specializes in human­like bots，developed a robotic walking partner that could make small talk based on its surroundings，which，he hopes，might motivate people to get out and exercise more.The bot rests on a person’s shoulder like a boxy parrot.It weighs about a pound and a half and sits roughly 8.5 inches high，and is 3.5 inches wide and 10 inches long.A microphone，a speaker，and an internal camera allow it to communicate.It’s even equipped with a smile.Kanda and his team collected video from five different locations，including a garden and a shopping mall，and created a dataset of small talk topics related to each location.Then they programmed the robot to associate visual cues with specific topics.A special speech software provided the robot with a voice.Near a group of parked cars，for example，it might say，“In a big parking lot， sometimes I forget where I parke d.”They tested the robot on 15 volunteers，10 males and 5 females，who were paid and averaged about 26 years old.“Have you ever blown a puff of dandelion（蒲公英） seeds into the air？”The robot asked a particip ant，who smiled and responded，“Yes，I often did that w hen I was a child.” Although several participants noted the robot’s weight，Kanda was surprised that no one considered the experience strange or funny.“I guess people enjoy new technologies，” he said.Just like a human partner，Kanda’s bot isn’t perfect.It’s not able to go for walks in heavy rain and，while the robot can make expressions，it can’t really holda conversation，about which Kanda is most worried.Despite its limits，Kanda was comforted by the bot’s presence.“I felt a kind of sense of being with someone，”he said，“particularly when it spoke.”【解题导语】本文主要介绍了新研发的陪人散步的机器人。

“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. I’d always want ed to be an inventor, and she wanted me to follow my passion.I was working at a financial firm in New York City with a bunch of very smart people, and I had a brilliant boss that I much admired. I went to my boss and told him I wanted to start a company selling books on the Internet. He took me on a long walk in Central Park, listened carefully to me, and finally said, “That sounds like a really good idea, but it would be an even better idea for someone who didn’t already have a good job. ” That logic mad e some sense to me, and he convinced me to think about it for 48 hours before making a final decision. Seen in that light, it was really a difficult choice, but ultimately, I decided I had to give it a shot. I didn’t think I’d regret trying and failing. An d I suspected I would always be haunted by a decision to not try at all.After much consideration, I took the less safe path to follow my passion, and I’m proud of that choice. For all of us, in the end, we are our choices.【文章大意】本文讲述了亚马逊网站的创始人的成长故事。

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! The idea to build it could date back to nearly 70 years ago—about as old as some of your grandparents!Yesterday, it was finally ready!It’s 35 miles long and runs 7,500 feet beneath the Swiss Alps, a famous mountain range in Switzerland. 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. The Gotthard Base Tunnel is a wonder of engineering! Make us want to visit it!6.When did people first have the idea of building the Tunnel?A.About 70 years ago.B.Half a century ago.C.Twenty-five years ago.D.Seven years ago.7.What can we learn about the Tunnel?A.It used to be an old tunnel.B.It has just been completed.C.It connects all European countries.D.It runs over a range of mountains.8.What may be the purpose of building the Tunnel?A.To improve traffic.B.To increase employment.C.To attract donation.D.To stop pollution.9.What can be inferred about the Tunnel?A.It will cause conflicts among countries.B.It will be of little benefit to the locals.C.It may do damage to the environment.D.It may become a tourist attraction.Ⅱ.语法填空(2018安徽高中十校联盟高三摸底)阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。
