Unit 3 Inventors and inventions李仕才一、阅读理解A new “smart bin” could mean the end of environment-conscious families spending hours sorting tins, cartons, bottles, and cardboard for recycling.The invention, which can help sort rubbish into recycling categories without needing people to operate. It is being trialed in Poland and is set to go on sale in UK within a few years.The bin, designed by start-up company Bin.E, recognizes different type of waste via a system positioned inside the bin which uses sensors, image recognition and artificial intelligence. Once waste is placed inside, the camera and sensor identify its type and place it in one of the smaller bins. Then it compresses the waste so it occupies less space.It is thought that the bin could be stocked by department stores such as John Lewis, which said it is introducing more new hi-tech recycling bins. Matt Thomas, a buyer at John Lewis, gave us the reason, “We’ve recently seen a jump in specialist bins sales, with a 25 percent increase in the last few months alone. We have noticed our customers are becoming more and more focused on sustainability. In response to this demand, we are really excited to introduce a smart bin this autumn/winterseason-designed to make recycling more efficient and functional for the everyday home."Bin. E’s official release on the market will take place in 2018. However, at first only a larger version designed for offices will be available. The office bin will sell at £ 430 while customers will need to pay a £ 107 subscript ion fee for an accompanying smartphone app, which hooks them up with collection services. A spokesman at Bin. E said that home version of the bin will be cheaper and will not include a monthly payment.They added: “After the office version, we plan to crea te an outdoor version and later the home version. We decided to go for the outdoor version for public areas first because it is more difficult to organize an efficient waste segregating system than in our homes.”1.What do we know about about a new “smart bin” from the first paragraph?A. It works automatically.B. It has been used widely.C. It is easy to operate.D. It is very expensive.2.What does the underlined word “it” in Paragraph 2 refer to?A. The waste.B. The camera.C. The bin.D. The sensor.3.Why is John Lewis introducing more new hi-tech recycling bins?A. To change people’s behaviour,B. To satisfy increasing demands.C. To popularize new technology.D. To make them more famous.4.Where will the first version of new “smart bin” be used according to Bin. E’s official?A. At home.B. In the supermarket.C. In the open air.D. In the office.【文章大意】本文介绍了一款可以智能分类垃圾的“智能垃圾箱”。
2019高考英语一轮选训习题 Unit 3 Inventors and inventions(含解析
选修8 Unit 3 Inventors and inventions李仕才Ⅰ.阅读理解Two of the saddest words in the English language are “if only”. I live my life with the goal of never having to say those words, because they convey regret, lost opportunities, mistakes, and disappointment.My father is famous in our family for saying, “Take the extra minute to do it right.” I always try to live by the “extra minute” rule. When my children were young and likely to cause accidents, I always thought about what I could do to avoid an “if only ” moment, whether it was something minor like moving a cup full of hot coffee away from the edge of a computer, or something that required a little more work such as taping padding (衬垫) onto the sharp corners of a glass coffee table.I don’t only avoid those“if only” moments when it comes to safety. It’s equally important to avoid “if only” in our personal relationships. We all know people who lost a loved one and regretted that they had foregone an opportunity to say “I love you” or “I forgive you”. When my father announced he was going to the eye doctor across from my office on Good Friday, I told him that it was a holiday for my company and I wouldn’t be there. But then I thought about the fact that he’s 84 years old and I realized that I shouldn’t give up an opportunity to see him. I called him and told him I had decided to go to work on my day off after all.I know there will still be occasions when I have to say “if only” about something, but my life is definitely better because of my policy of doing everything possible to avoid that eventuality(可能发生的事). And even though it takes an extra minute to do something right, or it occasionally takes an hour or two in my busy schedule to make a personal connection, I know that I’m doing the right thing. I’m buying myself peace of mind and that’s the best kind of insurance for my emotional well-being.1.Which of the following is an example of the “extra minute” rule ?A. Start the car the moment everyone is seated.B. Leave the room for a minute with the iron working.C. Wait for an extra minute so that the steak tastes better.D. Move an object out of the way before it trips someone.2.The author decided to go to her office on Good Friday to __________.A. keep her appointment with the eye doctorB. meet her father who was already an old manC. join in the holiday celebration of the companyD. finish her work before the deadline approaching3.The underlined word “foregone” in Paragraph 3 is closed in meaning to “_________”.A. abandonedB. lackedC. avoidedD. wasted4.What is the best title for the passage ?A. The Emotional Well-beingB. The Two Saddest WordsC. The Most Useful RuleD. The Peace of Mind【文章大意】这篇文章主要讲解的是作者对于最悲哀的两个单词if only 的理解及看法。

Unit 3 Inventors and inventionsⅠ.阅读理解AEarly one morning, more than a hundred years ago, an American inventor called Elias Howe finally fell asleep. He had been working all night on the design of a sewing machine but he had run into a very difficult problem: It seemed impossible to get the thread to run around the needle without any problems.Though he was tired, Howe slept badly. He turned and turned. Then he had a dream. He dreamt that he had been caught by terrible savages whose king wanted to kill him and eat him unless he could build a perfect sewing machine. When he tried to do so, Howe ran into the same problem as before. The thread kept getting caught around the needle. The king flew into the cage and ordered his soldiers to kill Howe. They came up towards him with their spears raised. But suddenly the inventor noticed something. There was a hole in the tip of each spear. The inventor awoke from the dream, realizing that he had just found the answer to the problem. Instead of trying to get the thread to run around the needle, he should make it run through a small hole in the center of the needle. This was the simple idea that finally made Howe design and build the first really practical sewing machine.Elias Howe was not the only one in finding the answer to his problem in this way. Thomas Edison, the inventor of the electric light, said his best ideas came into him in dreams. So did the great physicist Albert Einstein. Charlotte Bronte also drew in her dreams in writing Jane Eyre.To know the value of dreams, you have to understand what happens when you are asleep. Even then, a part of your mind is still working. This unconscious (无意识的), but still active part understands your experiences and goes to work on the problems you have had during the day. It stores all sorts of information that you may have forgotten or never have really noticed. It is only when you fall asleep that this part of the brain can send messages to the part you use when you are awake. However, the unconscious part acts in a special way. It uses strange images which the conscious part may not understand at first. This is why dreams are sometimes called “secret messages to us”．篇章导读：本文是一篇说明文。

Nowadays a third of primary schoolchildren in China are suffering from psychological ill-health as a result of classroom stress and parental pressure, according to a study published on Tuesday.The problem is so bad that urgent measures are needed, warns the study, led by British and Chinese researchers.The investigation surveyed 2, 191 pupils aged 9 to 12 in nine schools in urban and rural Zhejiang, a relatively prosperous coastal province in eastern China.Eighty-one percent of the youngsters said they worried “a lot” about exams, 63 percent feared being punished by their teachers, 44 percent had been physically bullied at least sometimes—with boys likelier to be victims than girls—and 73 percent had been physically punished by their parents.Most of the children complained they struggled to cope with the amount of homework they were assigned.Over one-third reported headaches or abdominal pains—psychosomatic symptoms of stress—at least once a week. The most stressed children reported incidence of aches or pains of four times a week.The investigation, led by Therese Hesketh, a professor at University College London (UCL) Centre for International Health and Development, pointed the finger at extreme competitiveness in China’s education system, from the onset of primary school.“The competitive and punitive educational environment leads to high levels of stress and psychosomatic symptoms, ” the authors say.“Measures to reduce unnecessary st ress on children in schools should be introduced urgently. ”The paper appears in Archives of Disease in Childhood, a peer-reviewed journal of the British Medical Association (BMA).The “urban” setting for the study was Hangzhou, the provincial capital of Zhejiang, while the “rural” setting was a poor county in Quzhou prefecture, in the west of the province.The study highlights some of the complexities that, it says, explain the demands for academic excellence and intolerance of failure.One factor is t he country’s dramatic rise in prosperity, which has created “previously unheard-of possibilities for upward mobility” and in turn stoked pressures on children to do well at school.Other reasons are China’s one-child policy and the Confucian traditions of respect for parents and elders, filial piety, obedience and discipline.“The aspirations of many parents, who had limited educational opportunities themselves are now invested in their only children, ” it says.Previous studies on school-related stress and its impact on health are few and generally come from Scandinavia.A 2008 assessment among 10-to 13-year-old in Sweden found that 21 percent of boys and 30 percent of girls experienced headache, and 17 percent of boys and 28 percent of girls experienced abdominal pain at least once per week.【文章大意】本文是一篇报告。

Unit 3 Inventors and inventions Ⅰ.阅读理解(2017重庆育才中学高三入学考试)A machine that takes sweat-laden (浸满汗水的) clothes and turns the sweat into drinking water is in use in Sweden. The machine makes the clothes turn round quickly, heats them to remove the sweat, and then passes the steam through a kind of special material to make purified water.Since it has been brought into use, its creators say more than 1000 people have drunk others’ “sweat” in Gothenburg. They add the liquid is cleaner than local tap water.Th e device was built for the United Nations’ child-focused charity UNICEF to promote a campaign highlighting the fact that 780 million people in the world lack access to clean water.The machine was designed and built by the engineer Andreas Hammar, known locally for his appearances on TV tech show “Mekatronik”. He said the key part of the sweat machine was a new water purification part developed by a company named HVR.“It uses a technique called membrane distillation (膜蒸馏),” he told the BBC.“We use a special kind of material that only lets steam through but keeps bacteria, salts, clothing fibers and other things out. They have something similar to the International Space Station, but our machine is cheaper to build. The amount of water it produces depends on how sweaty the person is, but one person’s T-shirt typically produces 10ml, about a mouthful.”The device has been put on show at the Gothia Cup—the world’s largest international youth football tournament. Mattias Ronge, chief executive of Stockholm-based advertising agencyDeportivo, said the machine had helped raise awareness of UNICEF, but in reality had its limitations.“People haven’t produced as much sweat as we hoped—right now the weather in Gothenburg is lousy,” Mattias Ronge said. “So we’ve equipp ed the machine with exercise bikes and volunteers are cycling like crazy. Even so, the demand for sweat is greater than the supply. And the machine will never be produced in large numbers, since there are better solutions out there such as water purifying pills.”1.Which of the following is the disadvantage of the sweat machine?A.It takes too long for the machine to produce water.B.The amount of water the machine produces is rather limited.C.It costs a large amount of money to build the machine.D.The water processed by the machine is not clean enough.2.UNICEF is mentioned in the text to .A.show how the sweat machine worksB.explain why the sweat machine was inventedC.show the importance of the United NationsD.tell us who invented the sweat machine3.What did Mattias Ronge think of the sweat machine?A.It could only be used in summer.B.It did not work at all.C.It was not worth popularizing.D.The water it produced tasted sweet.4.The text is written mainly to tell us that .A.a machine which turns sweat into drinking water is inventedB.780 million people in the world lack access to clean waterC.a better solution to purifying dirty water is discoveredD.the pill which turns dirty water into clean water is producedⅡ.七选五(2018山东寿光现代中学高三开学考试)Ways to Worry LessDo you want to worry less? Of course you do. That’s like asking if I can send you free bacon. Worry is like black mold—it appears in damp conditions and spreads uncontrollably. And very often we don’t realize it’s there until it’s killing us. We must get rid of worry before it destroys us. But how should we do it? 1Do what you need to do.2 You ought not to avoid tough projects or hard conversions. If you don’t do what you should be doing, you will end up spending the rest of the time worrying about the must-do things. Believe it or not, the anxiety that comes from the worry is much worse than the task we’re worried about.3I think many of us act like we’re puppets(木偶)in a play and we’re waiting for something or someone to put us in the right place. We just react to whatever is going on. 4 We need to live purposefully. Nothing can cause more worry than purposelessness.Make plans.You can’t have intentionality without making plans. Making plans will enable you to achieve your aim s more smoothly. However, your plans aren’t set in stone. You can adjust your plans flexibly. Accept changes. 5There are other ways to lessen worry. As long as you are determined to take action, you will live a worry-free life.A.Worry ruins creativity.B.Get more purposeful.C.Do what you should be doing.D.We need to stop letting life just happen.E.Make new plans and then move forward.F.You do the same things as the people around you do.G.Here are some effective ways to deal with it.Ⅲ.完形填空(2017山东潍坊一模)A middle-aged man named Douglas lives alone on the fourth floor of an apartment building.He keeps himself off his 1 ,never saying hello to anyone.He leaves his 2 out in thehallway.He 3 complains(抱怨)about all the inconvenience caused by his neighbours,even getting 4 when Catherine and David,the couple living next door,have a baby.Instead of saying 5 ,he 6 his concern about his own sleep.Then one day Mr.Douglas is surprised to see his garbage is 7 to be found.In its place is a note,“Glad to clear up the garbage to 8 you a trip.
