单元加餐练Ⅰ.阅读理解ATo us it seems so natural to put up an umbrella to keep the water off when it rains, but actually the umbrella was not invented as protection against the rain. Its first use was as a shade against the sun!Nobody knows who first invented it, but the umbrella was used in very ancient times. Probably the first to use it were the Chinese in the 11th century BC.We know that the umbrella was used in ancient Egypt and Babylon as a sunshade. And there was a strange thing connected with its use: it became a symbol of honor. In the Far East in ancient times, the umbrella was allowed to be used only by those in high office.In Europe, the Greeks were the first to use the umbrella as a sunshade. And the umbrella was commonly used in ancient Greece. But it is believed that the first persons in Europe to use the umbrella as protection against the rain were the ancient Romans.During the Middle Ages, the use of umbrella practically disappeared. Then it appeared again in Italy in the late 16th century. And again it was considered as a symbol of power. By 1680, the umbrella appeared in France and later in England.By the 18th century, the umbrella was used against rain throughout most of Europe.Umbrellas have not changed much in style during all this time, though they have become much lighter in weight. It wasn't until the twentieth century that women's umbrellas began to be made, in a whole variety of colors.篇章导读：本文是一篇说明文。

单元加餐练Ⅰ.阅读理解A(2017·浙江高考)Getting less sleep has become a bad habit for most American kids. According to a new survey(调查) by the National Sleep Foundation, 51% of kids aged 10 to 18 go to bed at 10 pm or later on school nights, even though they have to get up early. Last year the Foundation reported that nearly 60% of 7- to 12-year-olds said they felt tired during the day, and 15% said they had fallen asleep at school.How much sleep you need depends a lot on your age. Babies need a lot of rest: most of them sleep about 18 hours a day！Adults need about eight hours. For most school-age children, ten hours is ideal(理想的). But the new National Sleep Foundation survey found that 35% of 10-to 12-year-olds get only seven or eight hours. And guess what almost half of the surveyed kids said they do before bedtime？Watch TV.“More children are going to bed with TVs on, and there are more opportunities(机会)to stay awake, with more homework, the Internet and the phone，”says Dr Mary Carskadon, a sleep researcher at Brown University Medical School. She says these activities at bedtime can get kids all excited and make it hard for them to calm down and sleep. Other experts say part of the problem is chemical. Changing levels of body chemicals called hormones not only make teenagers' bodies develop adult characteristics, but also make it hard for teenagers to fall asleep before 11 pm.Because sleepiness is such a problem for teenagers, some school districts have decided to start high school classes later than they used to. Three years ago, schools in Edina, Minnesota, changed the start time from 7：25 am to 8：30 am. Students, parents and teachers are pleased with the results.篇章导读：本文是一篇调查报告。

单元加餐练Ⅰ.阅读理解AMandara seemed to know something big was about to happen. So she let out a yell, caught hold of her 2-year-old daughter Kibibi and climbed up into a tree. She lives at the National Zoo in Washington DC.And on Tuesday, August 23rd, witnesses said she seemed to sense the big earthquake that shook much of the East Coast before any humans knew what was going on. And she's not the only one. In the moments before the quake, an orangutan (猩猩) let out a loud call and then climbed to the top of her shelter.“It's very different from their normal call，” said Brandie Smith, the zookeeper. “The lemurs (monkey-like animals of Madagascar) will sound an alarm if they see or hear something highly unusual.”But you can't see or hear an earthquake 15 minutes before it happens, can you? Maybe you can—if you're an animal. “Animals can hear above and below our range of hearing，”said Brandie Smith. “That's part of their special abilities. They're more sensitive to the environment, which is how they survive.”Primates weren't the only animals that seemed to sense the quake before it happened. One of the elephants made a warning sound. And a huge lizard (蜥蜴) ran quickly for cover. The flamingoes (a kind of birds) gathered before the quake and stayed together until the shaking stopped.So what kind of vibrations (震动) were the animals picking up in the moments before the quake? Scientist Susan Hough said earthquakes produce two types of waves—a weak “P” wave and then a much stronger “S” wave. The “P” stands for “primary”. And the “S” stands for “secondary”. She thinks the “P” wave might be what sets the animals off.Not all the animals behaved unusually before the quake. Forexample, Smith said the zoo's giant pandas didn't jump up until the shaking actually began. But many of the other animals seemed to know something was coming before it happened. “I'm not surprised at all，”Smith said.篇章导读：本文是一篇说明文。

单元加餐练Ⅰ.阅读理解ACan you believe that there used to be a consensus in society that opposed the writing of novels by authoresses? Clearly this restriction must have operated at a time when there was no equality of opportunity for women. Amazingly, it was a generally held view only 100 years ago in England. In a strange contradiction, this period produced a couple of most courageous and gifted authoresses. Here are three of them.Jane Austen(1775-1817)All of the six completed novels of Jane Austen dealt with the problems and limitations of women's choices. At her time, the only respectable “career” for a woman was to marry, so the dilemma of her heroines' was also to marry but for love. Besides the content, the appeal of her works also lies in her refreshingly light and ironic style. Charlotte Bronte(1816-1855)Charlotte Bronte's novels were revolutionary for the explicit way they described women struggling against their restricted roles in society. Her heroines are outspoken in expressing their feelings, while demonstrating honesty and conscience in their choices. Her novel, Jane Eyre, published under a man's name, was very successful when it came out. The book was a revelation after the more reserved feelings expressed in Jane Austen's novels.George Eliot(1819-1880)Her novels examined the morally ambiguous concessions people made in their lives in order to succeed. In one of her books, Silas Marner, the hero discovers a little girl rejected by her own father. Her father did so for fear of losing his second wife's love—a mistake for which the couple both suffer.篇章导读：本文是一篇说明文。

单元加餐练Ⅰ.阅读理解AThis summer, I was part of something that I have carried with me every day since. An experience changed my life. The Kentucky YMCA has a program called Y－Corps, which are service trips of around 20 students. This summer, two trips were made across Kentucky, one down south and the other trip up north.I was on the Y－Corps Service to the North in Indianapolis, Indiana, and our trip began at the end of July. I had butterflies flying around me as my parents drove me to Louisville, where the Service to the North team would set off on a nine－day journey in a school bus. I knew some of the team members from previous Y－Conferences, but there were many that I had never met, and I had never participated in a service trip like this before. Though I was nervous, I was also ready to try something completely out of my comfort zone. Once we loaded the bus with our lightly packed suitcases and sleeping bags, we said our goodbyes to our parents and departed for an adventure that changed all of our lives.Wi th the Kentucky Y's motto: “Participate, don't anticipate”，we had no idea where we were headed. Road signs were our only clue of where we would be stopping. We did service work at a Middle Way House in Indiana, a Detroit Market Garden, a Pennsylvania YMCA for an invasive (侵略性的) species clean－up, the Upper Main Line Y in Pennsylvania to spend time with children at a summer camp, a Hurricane Sandy clean－up in Jersey Shore and the National Mall in Washington DC. We slept on floors of local YMCAs that would take us in for a night, and some nights we didn't have the opportunity to shower. We had late nights on the road driving from city to city, and early mornings to start the day journaling and reflecting on the day before.Though we were physically tired from the hard work, we still enjoyed the time to experience the culture of the areas we were in.篇章导读：本文是一篇记叙文，主要讲述了作者参加去美国北部城市印第安纳波利斯的义务服务旅行的情况，作者认为此次行程虽然辛苦却很有意义，令人难忘。

单元加餐练Ⅰ.阅读理解A(2018·浙江高考)FLORENCE, Italy—Svetlana Cojochru feels hurt. The Moldovan has lived here seven years as a caregiver to Italian kids and the elderly, but in order to stay she's had to prove her language skills by taking a test which requires her to write a postcard to an imaginary friend and answer a fictional job ad.Italy is the latest Western European country trying to control a growing immigrant (移民) population by demanding language skills in exchange for work permits, or in some cases, citizenship.Some immigrant advocates worry that as hard financial times make it more difficult for natives to keep jobs, such measures will become more a vehicle for intolerance than integration (融合). Others say it's only natural that newcomers learn the language of their host nation, seeing it as a condition to ensure they can contribute to society.Other European countries laid down a similar requirement for immigrants, and some terms are even tougher. The governments argue that this will help foreigners better join the society and promote understanding across cultures.Italy, which has a much weaker tradition of immigration, has witnessed a sharp increase in immigration in recent years. In 1990, immigrants numbered some 1.14 million out of Italy's then 56.7 million people, or about 2 percent. At the start of this year, foreigners living in Italy amounted to 4.56 million of a total population of 60.6 million, or 7.5 percent, with immigrants' children accounting for an ever larger percentage of births in Italy.Cojochru, the Moldovan caregiver, hoped obtaining permanent residence (居住权) would help her bring her two children to Italy; they live with her sister in Moldova, where salaries are among the lowest inEurope. She was skeptical that the language requirement would encourage integration.Italians always “see me as a foreigner，”an outsider, even though she's stayed in the country for years and can speak the local language fluently, she said.篇章导读：本文是一篇新闻报道。

单元加餐练Ⅰ.阅读理解A(2017·全国卷Ⅰ)Some of the world's most famous musicians recently gathered in Paris and New Orleans to celebrate the first annual International Jazz Day. UNESCO(United Nations Educational, Scientific and Cultural Organization) recently set April 30 as a day to raise awareness of jazz music, its significance，and its potential as a unifying (联合) voice across cultures.Despite the celebrations, though, in the US the jazz audience continues to shrink and grow older, and the music has failed to connect with younger generations.It's Jason Moran's job to help change that . As the Kennedy Center's artistic adviser for jazz, Moran hopes to widen the audience for jazz, make the music more accessible, and preserve its history and culture.“Jazz seems like it's not really a part of the American appetite，”Moran tells National Public Radio's reporter Neal Conan. “What I'm hoping to accomplish is that my generation and younger start to reconsider and understand that jazz is not black and white anymore. It's a ctually color, and it's actually digital.”Moran says one of the problems with jazz today is that the entertainment aspect of the music has been lost. “The music can't be presented today the way it was in 1908 or 1958. It has to continue to move, because the way the world works is not the same，”says Moran.Last year, Moran worked on a project that arranged Fats Waller's music for a dance party, “just to kind of put it back in the mind that Waller is dance music as much as it is concert music，”says Moran. “For me, it's the recontextualization. In music, where does the emotion (情感) lie? Are we, as humans, gaining any insight (感悟) on how to talk about ourselves and how something as abstract as a Charlie Parker record gets us into a dialogue about our emotions and our thoughts？Sometimeswe lose sight that the music has a wider context，”says Moran, “so I want to continue those dialogues. Those are the things I want to foster.”篇章导读：本文是一篇说明文。

高中英语 Unit 2 Healthy eating 单元加餐练3高一3英语试题
感顿市安乐阳光实验学校单元加餐练Ⅰ.阅读理解Good health is the most valuable thing a person can have, but one cannot take good health for granted.It is important to remember that the body needs proper care in order to be healthy.There are three things that a person can do to help stay in good shape：eat right food, get enough sleep, and exercise regularly.Proper nutrition (营养) is important for good health.Your body cannot work well unless it receives the proper kind of “fuel (燃料)”. Don't eat too much food with lots of sugar and fat.Eat plenty of foods high in protein, like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins and minerals. However, don't overeat.It is not helpful to be overweight.Getting the proper amount of sleep is also important.If you don't get enough sleep, you feel tired and easily get angry.You have no energy.Over a long period of time a little amount of sleep may even result in a change of personality (人的个性)．Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed，and your mind will be sharp.Finally, get plenty of exercise.Exercise firms the body, strengthens the muscles, and prevents you from gaining weight.It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your lifespan (寿命)．Any kind of exercise is good.Most sports are excellent for keeping the body in good shapes：basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.If everybody were to eat the right foods, get plenty of sleep and exercise regularly, the world would be a happier and healthier place.We would all live to be much older and wiser.语篇解读：本文是一篇说明文。

Unit 3 A healthy life单元加餐练Ⅰ.阅读理解AIs there anything more important than health? I don’t think so.“Health is the greatest wealth （财富），” wise people say。
You can’t be good at your studies or work well when you are ill。
If you have a headache， toothache， backache， earache or bad pain in the stomach, if you complain of a bad cough， if you run a high temperature and have a bad cold， or if you suffer from high or low blood pressure, I think you should go to the doctor.The doctor will examine your throat, feel your pulse, test your blood pressure，take your temperature， sound your heart and lungs, test your eyes, check your teeth or have your chest X。

单元加餐练Ⅰ.阅读理解A(2017·北京高考)Hollywood's theory that machines with evil (邪恶的) minds will drive armies of killer robots is just silly. The real problem relates to the possibility that artificial intelligence (AI) may become extremely good at achieving something other than what we really want. In 1960 a well-known mathematician Norbert Wiener, who founded the field of cybernetics (控制论), put it this way：“If we use, to achieve our purposes, a mechanical agency with whose operation we cannot effectively interfere (干预), we had better be quite sure that the purpose put into the machine is the purpose which we really desire.”A machine with a specific purpose has another quality, one that we usually associate with living things: a wish to preserve its own existence. For the machine, this quality is not in-born, nor is it something introduced by humans; it is a logical consequence of the simple fact that the machine cannot achieve its original purpose if it is dead. So if we send out a robot with the single instruction of fetching coffee, it will have a strong desire to secure success by disabling its own off switch or even killing anyone who might interfere with its task. If we are not careful, then, we could face a kind of global chess match against very determined, super intelligent machines whose objectives conflict with our own, with the real world as the chessboard.The possibility of entering into and losing such a match should concentrate the minds of computer scientists. Some researchers argue that we can seal the machines inside a kind of firewall, using them to answer difficult questions but never allowing them to affect the real world. Unfortunately, that plan seems unlikely to work：we have yet to invent a firewall that is secure against ordinary humans, let alone super intelligent machines.Solving the safety problem well enough to move forward in AI seems to be possible but not easy. There are probably decades in which toplan for the arrival of super intelligent machines. But the problem should not be dismissed out of hand, as it has been by some AI researchers. Some argue that humans and machines can coexist as long as they work in teams—yet that is not possible unless machines share the goals of humans. Others say we can just “switch them off” as if super in telligent machines are too stupid to think of that possibility. Still others think that super intelligent AI will never happen. On September 11, 1933, famous physicist Ernest Rutherford stated, with confidence, “Anyone who expects a source of power in the transformation of these atoms is talking moonshine.” However, on September 12,1933, physicist Leo Szilard invented the neutron-induced (中子诱导) nuclear chain reaction.篇章导读：本文是一篇议论文。
人工智能随着科技的发展可能超出人类的控制，人类应如何应对此类安全问题，文章对此进行了讨论。
1．Paragraph 1 mainly tells us that artificial intelligence may ________ .A．run out of human controlB．satisfy human's real desiresC．command armies of killer robotsD．work faster than a mathematician答案：A段落大意题。
由第一段中的“artificial intelligence(AI) may become extremely good at achieving something other than what we really want”并结合本段内容可推断出，第一段主要告诉我们人工智能可能会超出人类的控制。
故选A。
2．Machines with specific purposes are associated with living things partly because they might be able to ________ .A．prevent themselves from being destroyedB．achieve their original goals independentlyC．do anything successfully with given ordersD．beat humans in international chess matches答案：A推理判断题。
由第二段第一句“A machine with a specific purpose has another quality, one ... associate with living things: a wish topreserve its own existence.”及该段内容可知，具有特殊用途的机器与生物有联系，部分是因为这种机器可能会防止自己被损害。
故答案选A。
3．According to some researchers，we can use firewalls to ________ .A．help super intelligent machines work betterB．be secure against evil human beingsC．keep machines from being harmedD．avoid robots' affecting the world答案：D细节理解题。
由第三段中的“Some researchers argue that we can seal ... never allowing them to affect the real world.”可知，一些研究者认为，我们可以把这些机器封闭在一种防火墙内，用它们来解决难题，但从不允许它们影响真实世界，故选D项“避免机器人影响世界”。
4．What does the author think of the safety problem of super intelligent machines?A．It will disappear with the development of AI.B．It will get worse with human interference.C．It will be solved but with difficulty.D．It will stay for a decade.答案：C推理判断题。
由最后一段首句“Solving the safety problem well enough to move forward in AI seems to be possible but not easy.”可知，作者认为，解决超级智能机器的安全问题是可能的，但并非易事。
