2020海淀二模Once considered an optional lifestyle choice, recycling has become a commonplace activity in most areas. One type of recycling, called downcycling, involves re-purposing a material into a new product of lesser quality. 46Downcycling is also known as downstream recycling. It is most common in terms of industrial materials. These products lose their value as they are recycled, which limits their capacity for new use. 47 White writing paper, for example, is often downcycled into cardboard; once downcycled to this new form, it can no longer be used as white paper again. Another example of downcycling includes the use of plastic components.Giving products a new life is considered a good way to reuse materials and avoid waste. Once downcycled to their full capacity, however, these materials are eventually so degraded that they cannot be reused further. Since downcycled products are considered of lower quality than their original form, they cannot be used in remaking their original product.48 Plastic, glass, and aluminium products coded with the number one may be remade into something of equal or greater value. This type of recycling is known as upcycling, and represents the forward compatibility of recycled components. Materials available for downcycling, such as water, juice, and milk bottles, are coded with the number two. 49Items available for downcycling often require additional chemicals, energy, and other treatments in order to transform them into something usable. Durable plastic products in particular require much additional treatment. Trash bins, tables, and chairs are also considered materials with a high energy cost to recycle.When a product reaches a code seven, it is considered no longer recyclable. 50 Since these products can no longer be made into new ones, they will either have to be reused or discarded, typically in a landfill.A.These recycled materials may often be put into new use.B.It can include varying grades of plastic, paper products, and other materials.C.Their recycled form is typically both weaker and cheaper than their original one.D.They may not be used to contain food-grade items again upon being downcycled.E . Products are provided with codes to determine their grades and whether or not they may be recycled.F. A code will determine the type of the recycled materials and give an idea of how many times they canbe recycled.G.This usually occurs when a substance is blended with other substances, such as different types ofplastic with various recycling codes.46.B 47.

In Washington, DC, 14 of the first 17 days of May were rainy. (46). It means that for me, Mary has been one of the months I’ ve felt the sleepiest. The dull weather can hit almost all of our senses in a way that gives a sign to us it is time for a sleep.First, there’ s what we see-or rather, what we don’ t. (47) When it's raining and skies are cloudy, we miss out our body's internal alarm clock. As Naomi, a scientist from Central on Queensland University said, when you don't see the sunlight first thing in the morning, your body never gets the signal that it needs to shift into daytime mode.(48) Plants produce oils during dry periods, possibly to stop seeds from developing. When it rains, the water brings out the oils and they mix with a chemical to create a "musky” smell. (49). Additionally, after a thunderstorm there's a chance you may smell ozone(臭氧), which is generated when lightning interacts with the air. Some compare its smell to that of clean bed sheets.Rain sounds are also comforting. The rhythmic pattern of rain hitting a roof, umbrella, or the ground below is called "pink noise." Pink noise is a category of background noise that has all of the frequencies that human can hear and has lower volumes at higher frequencies. According to someresearch, it may improve our quality of sleep by decreasing our brain activity. (50) The difficulty in waking up, the fresh, earthy scents, and the peace of the rain tapping on windows are enough to make anyone want to go back to bed for the day. Sadly, none of this evidence is enough to justify doing so; but it can at least explain why you may feel a little sleepy on these cloudy days.A. Noises can make us feel sleepier during the daytime.B. The others have been cloudy and dull for at least part of the day.C. That earthy smell of rain can make you feel calm and comfortable.D. It makes it easier for us to wake up from our sleep the night before.E. Sunlight causes our bodies to stop producing what makes us sleepy at nightF. And you'll also smell that when you are in your garden turning over your soilG. You can listen to an hour of rain on a window here, if you intend to test it out46. B 47. E 48. C 49. F 50. G2020东城二模At one point or another, you’ve probably heard someone speak with confidence on a topic that they actually know almost nothing about. This phenomenon is known as the Dunning-Kruger effect, which refers to the finding that people who are relatively unskilled or unknowledgeable in a particular subject sometimes have the tendency to overestimate their knowledge and abilities.In a set of studies, researchers Justin Kruger and David Dunning asked participants to complete tests of their skills in a particular domain. Then, participants were asked to guess how well they hadscores on the test.David Dunning explains that “the knowledge and intelligence that are required to be good at a task are often the same qualities needed to recognize that one is not good at that task.” In other words, if someone knows very little about a particular topic, they may not even know enough about the topic to realize that their knowledge is limited. Importantly, someone may be highly skilled in one area, butIf people who know very little about a topi c think they’re experts, what do experts think of themselves? Interestingly, Dunning and Kruger found that although experts typically guessed their performance was above average, they didn’t realize quite how well they had done. They often make aWhat can people do to overcome the effect? Dunning and Kruger once had some of the participants take a logic test and then complete a short training session on logical reasoning. After theAfterward, the participants who scored in the bottom 25 percent lowered their estimate of how well they thought they had done on the initial test. In other words, one way to overcome the effect may be to learn more about a topic.The Dunning-Kruger effect suggests that we may not always know as much as we think we do.to learn more and by reading about opposing views, we can work to overcome the effect.A. Researchers found that the training made a difference.B. They assume that everyone else is knowledgeable, too.C. This happens when people don’t know much about a topic.D. All of them had a more accurate view of their performance.E. They found that participants tended to overestimate their abilities.F. This means that everyone can potentially be affected by the Dunning-Kruger effect.G. In some domains, we may not know enough about a topic to realize that we are unskilled. 46.E47.F48.B49.A50.G2020朝阳二模The Buy Nothing MovementSocial media, magazines and shop windows bombard(猛轰) people daily with things to buy, and British consumers are buying more clothes than ever before. The average person spends more than £1,000 on new clothes a year, which might not sound like much. 46 A lot of consumer spending is by means of credit cards. British people currently owe about £670 per adult to credit card companies. Also, people are spending money they haven’t earned to buy things they don’t need. Britain throws away 300,000 tons of clothing a year, most of which goes into landfill(垃圾填埋地) sites.47 But charity shops can’t sell all those unwanted clothes. A lot of clothes that charities can’t sell are sent abroad, causing even more economic and environmental problems.48 The idea originated in Canada in the early 1990s and then moved to the US. On Buy Nothing Day people organise various types of protests and cut up their credit cards. Throughout the year, Buy Nothing groups organise the exchange and repair of items they already own.The trend has now reached influencers on social media who now encourage their viewers not to buy anything at all for periods as long as a year. Two friends in Canada spent a year working towards buying only food. For the first three months they learned how to live without buying electrical goods, clothes or things for the house. For the next stage, they gave up services, for example, haircuts, eating out or buying petrol for their cars. 49The changes they made meant two fewer cars on the roads, a reduction in plastic and paper packaging and a positive impact on the environment from all the energy saved. 50 But even if you can’t manage a full year without going shopping, you can participate in the anti-consumerist movement by refusing to buy things you don’t need.A. In one year, they’d saved $55,000.B. If everyone followed a similar plan, the results would be impressive.C. Online shopping means it is easy for customers to buy without thinking.D. Second-hand clothes are often of too poor quality to recycle in charity shops.E. But that figure hides two far more worrying trends for society and for the environment.F. However, a different trend arises in opposition to consumerism—the ‘buy nothing’ trend.G. People might not realise the problems because they donate their unwanted clothes to charities.46.E47.G48.F49.A50.B2020丰台二模One major reason Americans don’t get enough exercise is that they feel they don’t have enough time. It can be difficult to squeeze in the 75 minutes of aerobic (有氧的) exercise per week that federal guidelines recommend. 46In a new analysis of 14 studies, researchers tracked deaths among more than 232,000 people from the U.S., Denmark, the U.K. and China over at least five years, and compared the findings with people’s self-reports about how much they ran. People who said they ran any amount were less likely to die than those who didn’t run at all. 47 This was true even for those who didn’t log a great deal of time. The analysis divided people into groups, with 50 minutes or less per week representing the group that ran the least—but still ran. “Regardless of how much you run, you can expect such benefits,” says Zeljko Pedisic, one of the authors of the new analysis published in the British Journal of Sports Medicine.The analysis is the latest to illustrate the benefits of running on the human body. It’s what we evolved (进化) to do. 48 But as leisure-time exercise, running keeps us healthy. “One of the best ways to avoid having to see a doctor,” Zeljko says, “is to stay physically active.”49 Running is good at guarding against cancer partly because it uses up blood sugar, starving the cancer cells that rely on it for fuel. And it protects you in other ways not necessarily measured in the latest research: by decreasing inflammation (炎症), for example, which is at the root of many diseases, and stimulating the production of a protein that improves brain health.50 Neither were how often people ran and the pace they kept. As long as you’re running, more isn’t always better, especially given that the risk of injury increases with repetition.A.People may no longer hunt wild animals for their next meal.B.The physical demands of running affect our body in a beneficial way.C.Some people run to prevent disease, and others run because it makes them feel better.D.Runners were 27% less likely to die for any reason, compared with nonrunners.E.But researchers point out, to infer something like that, they need the whole population measured.F.But new research suggests people may be able to get life-lengthening benefits by running for farless time.G.The good news is that running more than 50 minutes per week wasn’t linked to additionalprotections against dying.46.

Trying to keep up with the latest styles involves regular visits to the shopping malls and sometimes paying for expensive designer clothes. But the fashion often changes. 46Many stores now offer cheap “fast fashion”一low-price items that copy the styles of more expensive designer brands. Environmentalists are angered by the amount of energy involved in making these clothes and that many of them are made from non- recyclable materials. 47Eleanor Lawrie, a BBC reporter, says that people in the UK are the worst in Europe for getting rid of unwanted clothes every year. And she says, " On top of often poor labour conditions for workers, the fashion industry is also responsible for 20% of the world's waste water, and 10% of carbon emissions (排放).”This is something the fashion industry is becoming more aware of and has tried to find new crops of biomaterials to replace wasteful fabrics like cotton and leather. Examples include Pinatex, a leather-like material made from pineapple leaves. It's been used in collections by Hugo Boss and H&M.48 It is being used to create food, packaging and clothes.49 The current farming practice requires a massive amount of water and insect killer. Eleanor says, "About 15,000 litres of water are required to make one pair of jeans, while 95% of its material is cotton. " So, buying organic cotton is a better choice. And there is also Tencel, a natural product becoming increasingly popular. It's made by taking cellulose fiber (木质纤维素)from trees and its production is thought to use 95% less water than cotton processing.Professor Richard Blackbum from Leeds School of Design tells the BBC that creating sustainable fabrics is only part of the battle一buying reasonably, buying second hand and buying fewer clothes are obviously the more environmentally friendly choices for people. 50 If one can do that, he is starting to be sustainable.A.Cotton is a very resource-demanding crop to grow.B.And there's Mycelium, the root structure of mushrooms.C.Every year, a million tonnes of unwanted fabrics just get thrown away.D.Many of your clothes will then be left in the back of cupboards gathering dust.E.Recycled cotton can come from secondhand clothing or from fabrics' leftovers.F.This means the cheap fashionable items will have to be burned or go into landfill.G.One shouldn't consider buying any item of clothing unless he commits to 30 wears.46-50 D F B A G2020房山二模A study revealed that, in most occasions, the outcome on a given task can be improved whentwo people have helped each other instead of working on their own. As early as 1624 John Donne has already popularized the phrase ‘No man is an island’. And this is especially true, be it in the workplace, in doing scientific research, or working in events. One of the benefits of cooperation is that people can pool together their skills and wisdom towards a common aim. Because of this, they have a higher chance of being more successful. 46Teamwork promotes diversity. The very nature of teamwork requires a group of people from various backgrounds to come together and share their thinking.47 This level of diversity generates cultural understanding, increased communication through collective knowledge of approaches and a larger resource of opinions.48 Working within a team helps us to create an environment which inspires collective knowledge, resources and skills. Consequently, this allows us to pick some ideas and to reflect on our own way of thinking. Teamwork also encourages self-improvement because it helps us to expand our horizons and make better use of our own intrinsic capabilities. And since self-improvement helps us in seeking better ways to perform our role within a team, it improves both the efficiency and productivity of the team as a whole.Completion of task becomes easy. Each member has unique skills to help with the project. 49 For example, you may ask one person to do research, another to take charge of social media marketing, and another to look after delivery. Teamwork can get the most of each person’s strengths.50 For instance, tackling about climate change by researchers who come from different disciplines (学科) could potentially lead to ground-breaking researches. In the traditional research world,one researcher pursued a theme over several decades. However, academia is fostering a fresh research culture, whereby academic works advance through the creation of interdisciplinary research.A. Teamwork encourages healthy competition.B. It promotes peer learning and self-improvement.C. So a task can be assigned based on a person’s skills and expertise.D. There are many benefits we can gain out of teamwork and cooperation.E. The seeds of creativity and innovation spring from the exchange of ideas.F. As a result, different opinions and problem-solving methods can be formed.G. Cooperation has several benefits including shared risk, resources and knowledge.46. D47.F48.B49.C50.E2020昌平二模All book writing has to start somewhere, and the best place to kick off your manuscript ( 原稿) is by coming up with a great idea. 46 It can be an article you read from your local newspaper, a conversation you overheard at Starbucks, a recent experience you had during a vacation, etc. Y ouroverall idea should be narrowed down to one-to-two paragraphs, similar to the back cover copy you find on most books. When writing books, the idea is king. Always remember that.47 This doesn’t just mean fictional characters—memoirs ( 回忆录) and nonfiction books still have characters, even if those characters are based on real people. When you write your own book, you must ask yourself what makes this character unique, what is the No. 1 thing this character wants and what difficulties must he or she overcome to reach it. Readers love imperfect, yet relatable characters.48Maybe the most crucial step in the steps to writing a book, setting a deadline and sticking to it is essential. 49 Too many writers say they are going to write a book and, after starting strong, find excuses as to why they stopped (or are on a super-long pause from writing books). There are definitely reasonable reasons that could prevent you from book writing—help needed in the family, a health issue, etc. But if you’re serious about writing a book, you have to make time for it. Deadlines will push you to do just that.Y ou can spend as much time as you want reading tips for writing a book, how to write books and how to edit your novel—and you should spend some time doing that. Y ou should invest in studying the craft and learning how to write a bestseller. 50 Do it during your lunch break. Do it while waiting for the kids at soccer practice. Do it after everyone goes to bed. There’s no official book writing model, there’s just you, a pen and a paper (or a computer, of course).A.Strive to make your characters as interesting as possible.B.But you’ll never write a book if you don’t spend time writing.C.Now discover our best tips for how to write a book effectively.D.It’s time to further your writing career by diving deeper into deadline.E.Book ideas come in all shapes and sizes and can be found anywhere.F.It’s the difference between serious writers and those who are merely dreamers.G.H ow to start writing a book begins with an idea, but your idea needs to be carried out withwell-developed characters.46.

When you choose to be a victim, the world is a cold and difficult place. 46 “They” are wrong and bad, and life is terrible as long as “they” are around. Or you may blame yourself for all your problems, thus internalizing(内化)your victimization. The truth is, your life is likely to stay that way as long as you feel a need to blame yourself or others.47 They know there are individuals who might like to control their lives, but they don’t let this get in the way. They know they have their weaknesses, yet they don’t blame themselves when they fail. 48 They believe their dance with each sacred (神圣的) moment of life is a gift and that storms are a natural part of life which can bring the rain needed for emotional and spiritual growth.Victims and creators live in the same physical world and deal with many of the same physical realities, yet their experience of life is worlds apart. Victims relish (沉溺) in anger, guilt, and other emotions that cause others—and even themselves—to feel like victims, too. Creators consciously choose love, inspiration, and other qualities which inspire not only themselves, but all around them. 49In reality, all of us play the victim or the creator at various points in our lives. One person, on losing a job or a special relationship, may feel as if it is the end of the world and sink into terrible suffering for months, years, or even a lifetime. 50 He may choose to first experience the grief, then accept the loss and soon move on to be a powerful creative force in his life.In every moment and every circumstance, you can choose to have fuller, richer life by setting a clear intention to transform the victim within, and by inviting into your life the powerful creator that you are.A. Whatever happens, they have choice in the matter.B. Compared with victims, creators are more emotional.C. One’s experiences determine his attitude toward life.D. Those who choose to be creators look at life quite differently.E. Another with the same experience may choose to be a creator.F. “They” did things to you which caused all of your pain and suffering.G. Both victims and creators always have choice to determine the direction of their lives. 46-50 FDAGE。
