高中英语人教版选修8练习：Unit 3 Inventors and inventions含解析

Unit 3 Inventors and inventions[导语]谈起“发明”，我们脑中浮现的总是飞机、大炮、电脑等这些高科技产品。

而下面的几个小发明虽然与高科技毫不沾边，但却同样能为我们的生活带来极大便利。

Ideas for creating a small inventionA small invention can do big things when it comes to making a task easier to do.When looking for a small invention idea，start by checking your kitchen drawers and cabinets.Is there something you need to help you in a task? Look in the bathroom and see if you can improve on the way something works.If you can create an item that does a job around the house, you have a small invention of your own.KitchenDinner plates have not changed in centuries except for the different materials used to make them.When you need to store leftover dinners，you usually wrap them in aluminum foil and plastic wrap.Dinner plate covers would save money and look much neater than the usual disposable covers.A spaghetti drainer flexible enough to fit inside a pot would be a tool every cook would have in stock.You would be able to take the pasta out of the boiling water and drain it at the same time，saving the cook from picking up a heavy pot of boiling water.BathroomA bathroom toilet paper dispenser that has an extra roll readywill solve the problem of running out of the necessary tissue paper.This can offer a rescue when your inconsiderate family member has emptied the toilet paper roll.[词海拾贝]1．cabinet n．贮藏柜，陈列柜2．aluminum foil铝箔3．drainer n．过滤器4．dispenser n．自动取物器[问题思考]判断正误(T/F)。

Well, the future is apparently now. The California Department of Motor Vehicles began giving permits in April for companies to test truly self-driving cars on public roads. The state also cleared the way for companies to sell or rent out self-driving cars, and for companies to operate driverless taxi services. California, it should be noted, isn’t leading the way here. Companies have been testing their vehicles in cit ies across the country. It’s hard to predict when driverless cars will be everywhere on our roads. But however long it takes, the technology has the potential to change our transportation systems and our cities, for better or for worse, depending on how the transformation is regulated. While much of the debate so far has been focused on the safety of driverless cars(and rightfully so), policymakers also should be talking about how self-driving vehicles can help reduce traffic jams, cut emissions(排放) and offer more convenient, affordable mobility options. The arrival of driverless vehicles is a chance to make sure that those vehicles are environmentally friendly and more shared. Do we want to copy — or even worsen — the traffic of today with driverless cars? Imagine a future where most adults own individual self-driving vehicles. They tolerate long, slow journeys to and from work on packed highways because they can work, entertain themselves or sleep on the ride, which encourages urban spread. They take their driverless car to an appointment and set the empty vehicle to circle the building to avoid paying for parking. Instead of walking a few blocks to pick up a child or the dry cleaning, they send the self-driving minibus. The convenience even leads fewer people to take public transport — an unwelcome side effect researchers have already found in ride-hailing(叫车) services. A study from the University of California at Davis suggested that replacing petrol-powered private cars worldwide with electric, self-driving and shared systems could reduce carbon emissions from transportation 80% and cut the cost of此卷只装订不密封班级姓名准考证号考场号座位号transportation infrastructure(基础设施) and operations 40% by 2050. Fewer emissions and cheaper travel sound pretty appealing. The first commercially available driverless cars will almost certainly be fielded by ride-hailing services, considering the cost of self-driving technology as well as liability and maintenance issues(责任与维护问题). But driverless car ownership could increase as the prices drop and more people become comfortable with the technology.KS5UPolicymakers should start thinking now about how to make sure the appearance of driverless vehicles doesn’t extend the worst aspects of the car-controlled transportation system we have today. The coming technological advancement presents a chance for cities and states to develop transportation systems designed to move more people, and more affordably. The car of the future is coming. We just have to plan for it.11. According to the author, attention should be paid to how driverless cars can __________.A. help deal with transportation-related problemsB. provide better services to customersC. cause damage to our environmentD. make some people lose jobs12. As for driverless cars, what is the author’s major concern?A. Safety.B. Side effects.C. Affordability.D. Management.13. What does the underlined word ＂fielded＂in Paragraph 4 probably mean?A. Employed.B. Replaced.C. Shared.D. Reduced.14. What is the author’s attitude to the future of self-driving cars?A. Doubtful.B. PositiveC. Disapproving.D. Sympathetic.BThere’s a new frontier in 3D printing that’s beginning to come into focus: food. Recent development has made possible machines that print, cook, and serve foods on a mass scale. And the i ndustry isn’t stopping there.Food productionWith a 3D printer, a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. Not everybody can do that — it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Foodini to “recreate forms and pieces” of food that are “exactly the same,” freeing cooks to complete other tasks. In another restaurant, all of the dishes and desserts it serves are 3D-printed, rather than farm to table.Sustainability(可持续性）The global population is expected to grow to 9.6 billion by 2050, and some analysts estimate that food production will need to be raised by 50 percent to maintain current levels. Sustainability is becoming a necessity. 3D food printing could probably contribute to the solution. Some experts believe printers could use hydrocolloids (水解胶体) from plentiful renewables like algae(藻类) and grass to replace the familiar ingredients(烹饪原料). 3D printing can reduce fuel use and emissions. Grocery stores of the future might stock "food" that lasts years on end, freeing up shelf space and reducing transportation and storage requirements.NutritionFuture 3D food printers could make processed food healthier. Hod Lipson, a professor at Columbia University, s aid, “Food printing could allow consumers to print food with customized nutritional content, like vitamins. So instead of eating a piece of yesterday’s bread from the supermarket, you’d eat something baked just for you on demand.”ChallengesDespite recent advancements in 3D food printing, the industry has many challenges to overcome. Currently, most ingredients must be changed to a paste(糊状物) before a printer can use them, and the printing process is quite time-consuming, because ingredients interact with each other in very complex ways. On top of that, most of the 3D food printers now are restricted to dry ingredients, because meat and milk productsmay easily go bad. Some experts are skeptical about 3D food printers, believing they are better suited for fast food restaurants than homes and high-end restaurants.15. What benefit does 3D printing bring to food production?A. It helps cooks to create new dishes.B. It saves time and effort in cooking.C. It improves the cooking conditions.D. It contributes to restaurant decorations.16. What can we learn about 3D food printing from Paragraphs 3?A. It solves food shortages easily.B. It quickens the transportation of food.C. It needs no space for the storage of food.D. It uses renewable materials as sources of food.17. According to Paragraph 4, 3D-printed food _____________.A. is more available to consumersB. can meet individual nutritional needsC. is more tasty than food in supermarketsD. can keep all the nutrition in raw materials18. What is the main factor that prevents 3D food printing from spreading widely?A. The printing process is complicated.B. 3D food printers are too expensive.C. Food materials have to be dry.D. Some experts doubt 3D food printing.19. What could be the best title of the passage?A. 3D Food Printing: Delicious New TechnologyB. A New Way to Improve 3D Food PrintingC. The Challenges for 3D Food ProductionD. 3D Food Printing: From Farm to Table 三、完形填空（共20小题；每小题1.5分，满分30分）A woman professor walked around in a classroom while she was teaching stress management to her students. As she___20___a glass of water, everyone ___21___they would be asked the “half-empty or half-full” question.___22___, with a smile on her face, she asked, “How ___23___is this glass of water?”Answers called out ___24___from eight to twenty ounces(盎司).She quieted the students down and then replied, “The absolute weight doesn’t ___25___. It all depends on how long I hold it. If I hold it for a minute, it’s not a ___26___. If I hold it for an hour, I’ll have an ache in my ___27___. If I hold it for a day, my arm will feel ___28___and paralyzed. In each case, the ___29___of the glass of water doesn’t change, but the longer I hold it, the heavier it becomes. Do you know why?”All the students kept silent and listened carefully, lost in thought.She continued, “Our ___30___and worries in life are like that glass of water. Think about them for a while and ___31___happens. Think about them a bit longer and they begin to ___32___. And if you think about them all day long, you will feel paralyzed— ___33___to do anything.”It’s important to remember to ___34___your stresses. As early in the evening as possible, put all your ___35___down. Don’t carry them through the evening and into the night. Remember to put the glass down!More often than not life gets terrible ___36___we think too much. And the moment you remove your burden, you’ll find yourself feeling so much more ___37___.So rather than moping around(闲逛）and feeling sorry for yourself, ___38___doing something about it. After all, life is too short to ___39___yourself to anything that’s not making you happy.20. A. drank B. served C. raised D. demanded21. A. argued B. wondered C. expected D. agreed22. A. Meanwhile B. Therefore C. Anyhow D. Instead23. A. much B. full C. little D. heavy24. A. ranged B. replied C. read D. remained25. A. affect B. drop C. matter D. work26. A. success B. point C. skill D. problem27.

A. catch up with B. take charge of C. put up with D. let go of35. A. burdens B. thoughts C. hardships D. feelings36. A. when B. till C. unless D. though37. A. excited B. worried C. satisfied D. relaxed38. A. keep B. finish C. start D. risk39. A. help B. commit C. throw D. abandon四、七选五（共5小题，每小题2分，满分10分）Every animal sleeps, but the reason for this has remained foggy. When lab rats are not allowed to sleep, they die within a month. 40One idea is that sleep helps us strengthen new memories. 41 We know that, while awake, fresh memories are recorded by reinforcing (加强) connections between brain cells, but the memory processes that take place while we sleep have been unclear.Support is growing for a theory that sleep evolved so that connections between neurons(神经元) in the brain can be weakened overnight, making room for fresh memories to from the next day. 42Now we have the most direct evidence yet that he is right. 43 The synapses in the mice taken at the end of a period of sleep were 18 per cent smaller than those taken before sleep, showing that the connections between neurons weaken while sleeping.If Tononi’s theory is right, it would explain why, when we miss a night’s, we find it harder the next day to concentrate and learn new information---our brains may have smaller room for new experiences.Their research also suggests how we may build lasting memories over time even though the synapses become thinner. The team discovered that some synapses seem to be protected and stayed the same size. 44 “You keep what matters,”Tononi says.A. We should also try to sleep well the night before.B. Ti’s as if the brain is preserving its most important memories.C. Similarly, when people go for a few days without sleeping, they get sick.D. The processes take place to stop our brains becoming loaded with memories.E. That’s why students do better in tests if they get a chance to sleep after learning.F. “Sleep is the price we pay for learning,” says Giulio Tononi, who developed the idea.G. Tononi’s te am measured the size of these connections, or synapses, in the brains of12 mice.五、书面表达（满分25分）假定你是李华，在校报英语专栏看到了学校“英语文化节”的一则招募启事，请阅读启事，并根据写作要点和写作要求写一封应征邮件。
