1、阅读理解(五)人造肉+如何决定+网络真假A 2019门头沟二模The UK should start producing lab-grown meat to help solve the worlds food crisis (危机), according to a research group. A report by the Adam Smith Institute says meat made in a laboratory is better for the environment and would be cheaper than meat produced from farm an

2、imals.Need for meat around the world is expected to increase by 70% by the year 2050. So could people be eating lab-grown meat in the future? Usually animals like cows are killed to produce the meat that people eat, but scientists have found a way to make meat in a laboratory without killing any ani

3、mals.Animals are made up of cells (细胞). Scientists worked out how to take cells from an animal, like a cow, and multiply (繁殖) them in a dish. In the end from one tiny cell, tens of billions of cells can be grown. These join together to form meat.In 2013, the first hamburger grown this way was eaten

4、in London. It took a year to produce and cost over 200,000 to make. Dr Mark Post, who created the worlds first hamburger from meat grown in a lab, told the BBC it “tastes exactly the same as the meat we know”. When two food critics(评论家) tried the burger in 2013, one said it was “close to meat” and a

5、nother said it tasted like a real hamburger. Its not just beef that is being created; companies are also working on other meat like turkey and chicken.The Adam Smith Institute says moving away from the present way meat is produced would help reduce greenhouse emissions(排放) by up to 96% and free up 9

6、9% of the land used in farming worldwide. They also think it will reduce chances of food poisoning(中毒) because the meat is grown under such controlled conditions. Jamie Hollywood from the Adam Smith Institute also told the BBC lab-grown meat could be a lot cheaper. He says the price has gone down in

10、w is it made?B 2019东城一模I recently spent an evening trying to choose a cup on Amazon. Nearly an hour later, after having read countless reviews about dozens of kinds, I felt tired and simply gave up. The next day, I happily bought the only kind the local store offered. Too many choices make us tired

11、and unhappy and lead us to avoid making a decision sometimes. Researcher Barry Schwartz calls this “choice overload”. “As the number of options(可选择的事物) increases, the costs in time and effort of collecting the information needed to make a good choice also increase,” writes Schwartz. “The level of ce

12、rtainty people have about their choice decreases. And the possibility that they will regret their choice increases.” Understanding how and why we make decisions can perhaps help us make better choices. We make poorer decisions when we are tired. The mind can only deal with so many options and make s

13、o many choices before it starts to lose energy. Thats why buys like candy bars and magazines at the checkout(付款处) in the store can be hard to resist. Weve used up all our good decision-making skills. The same goes for our workday. Making lots of decisions not only tires us, it can put us in a bad mo

14、od. Thats why its important to make your most important decisions in the morning rather than at the end of a tiring day.When were tired, we often save our energy by making choices based on a single factor(因素) like price, rather than considering all the other factors that go into making the best deci

15、sion. Another study out of Columbia University shows that this happens when people are given a lot of features(特点) to choose from when buying a car. After a while, people start asking for the common option rather than carefully weighing each decision. This can also happen when faced with a decision

16、in your creative work. Given endless options of which route to take, we sometimes end up going with the more usual path simply because its the easier way to go. So its important to put limits on your options, which can develop your creativity and help you make a better decision. In other words, lett

17、ing yourself have fewer options to choose from can help you arrive at a more creative answer.5. According to Barry Schwartz, the more options people have, .()A.the better choice they will makeB.the more easily they will make a choiceC.the happier they will feel to make a choiceD.the more likely they

18、 will regret their choice6. The word “resist” in Paragraph 3 probably means “”.()A.explain B.avoid C.decide D.afford7. When a person is tired from comparing many kinds of products, he is likely to .()A.consider the price mostB.choose a more common kindC.read more reviews from othersD.weigh all the f

20、ens have grown up online. They socialize online. They do homework online. And surely they get their news online. But because they are so comfortable with the Internet, they seldom question the news stories online and pass along to their friends.Now William Colglazier, a history teacher at a high sch

21、ool in America, is teaching his students how to think critically about online information and recognize a “fake(假的) news” story. His idea came from a study on peoples online reasoning at Stanford University. The study found that young people lack (缺少) ability to reason about the information on the I

22、nternet. Most middle school students in the study could not tell the difference between an advertisement and a news story, and high school and college students fully trusted the websites ending in “.org”.The good news is that, according to Colglazier, once teens realize theyve been duped, they have

23、strong will to tell truth from lies. “But they need some pointers on how to find dependable and persuasive evidence(证据) and how to recognize when others use poor argumentation,” he said. Some of the pointers that Colglazier offers his students include moving off the site to find more information abo

24、ut the site and the writers motivations(动机), looking past the first page of results in a google search and looking at the second or third page,and going beyond the “About Us” page on a website to find out more about the organization behind the news story.Colglazier has tips for parents as well. He s

25、ays its a good idea for parents to be “friends” with their kids on social media(媒体)to see what stories they are sharing. He also suggests parents watch their teens as they search for something online and ask questions like “Why did you click on that?” and “Do you trust this information?” Those quest

26、ions can lead kids to form habits of thinking critically about online information.Colglazier shared some of his course with other teens in Teen Vogue, a famous magazine. He hopes more kids would take away some knowledge about thinking critically when they read news online. “The Internet is both beau

27、tiful and ugly,” he said. “If people cannot tell real news from fake news, the results can be frightening.”9.When teens read a news story online, they .()A.seldom raise doubts about itB.always share it with their parentsC.usually pay attention to the websiteD.often consider it as an advertisement10.
