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.“T his 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 Salon 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 room of a friend，” said Matt Hart, with Aubrey Zoli making up the Local Stran gers, 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。

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。

Susan Brownell Anthony was a lady ahead of her time. She fought for women’s rights long before they became a popular issue.Susan was born on February 15, 1820, in Adams，Massachusetts. At that time, women had few rights. They could not own property. Money earned by a married woman belonged to her husband. Major decisions regarding children were made by the fathers. Women could not vote.At the age of 15, Susan became a schoolteacher. She taught for 15 years. Then she began organizing women’s groups to promote causes that were important to women. She helped gain better educational rights for women. She helped give married women possession of their earnings.After the Civil War, Susan became very involved in the women’s suffrage movement. After years of lecturing, writing, and appealing by Susan and other women, some parts of the United States changed their laws to give women the right to vote. The first state was Wyoming in 1869. Other areas and states gradually followed Wyoming’s decision. It was not until 1920 that the U．S. Constitution was changed to give all women voting rights.Susan Brownell Anthony died in 1906 at the age of 86. She was elected to the Hall of Fame for Great Americans in 1950. She was the first American woman to have a likeness(肖像) of her face on a coin. It was the 1979 Susan Brownell Anthony dollar.【解题导语】本文主要介绍了美国历史上著名的女权运动领袖Susan Brownell Anthony。

“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。
