26、Ten minutes of gentle exercise can immediately change how certain parts of the brain communicate and coordinate (协调) with one another and improve memory function, according to an encouraging new study.
The scientists invited 36 people of different ages to the lab and had them sit quietly on a fixed bicycle for 10 minutes or, on a separate visit, pedal the bicycle at a pace so gentle that it barely raised their heart rates. It also was short, lasting for only 10 minutes. Immediately after each session of the sitting or slow pedaling, the people completed a computerized memory test during which they would see a brief picture of, for instance, a tree, followed by a variety of other images and then a new image of either the same tree or a similar one. The people would press buttons to show whether they thought each image was new or the same as an earlier shot. The test is difficult, since many of the images closely resemble one another. It requires rapid, skillful scanning recent memories to decide whether a picture is new or known. Next, the scientists had each people repeat this process--riding or sitting on the bike for 10 minutes and then completing memory testing--but the testing now took place inside an M. R. I. machine(磁共振成像仪)that scanned the people's brains while they responded to the images.
Then the researchers compared results. The effects of the exercise were clear. The people were better at remembering images after they had ridden the bike, especially when the images most closely resembled one another. In other words, the harder their memories had to do their best, the better they performed after the exercise. The M. R. I. scans showed that memory parts of each people's brain lit up at the same time with parts of the brain associated with learning, indicating that these physically separate parts of the brain were better connected now than when the people had not first exercised.
【1】How did the researchers conduct the study?
A．By filling up questionnaires.
B．By interviewing many people.
C．By comparing experiment data.
D．By referring to historical reports.
【2】Who might benefit most from the study result?
A．The marketers promoting fixed bicycles.
B．The young people crazy about body building.
C．The white collars doing long-term mental work.
D．The blue-collars doing heavy physical labor work.
【3】Which of the following statements agrees with the study result?
A．The light exercise is only good for young people.
B．The more the exercise is, the better the brain works.
C．The exercise can coordinate different parts of the body.
D．The exercise has more positive effect when the brain works harder.
【4】What can be the best title for the text?
A．Even ten minutes' exercise may be good for the brain
B．There is no need for humans doing exercise every day
C．Only ten minutes' light exercise benefits the young most
D．Exercise can change people's brains and minds in a long time
27、A European Union program is letting blind people experience famous paintings for the first time. It uses three dimensional (3-D) printing to re-create famous paintings so that they can be touched.
One painting printed with the new technology is Gustav Klimt’s “The Kiss.” It is a popular attraction at the Belvedere Museum in Vienna, Austria. The painting shows a man and a woman standing in a field filled with flowers. They are wearing gold robes and have their arms around each other. The man leans down to kiss the woman.
Klimt finished the painting in 1908. Until now, people who have trouble seeing can not enjoy the artwork. But thanks to the reproduction (复制品) they can touch the piece and feel the ridges (隆起) and depressions (凹地). Andreas Reichinger started making 3-D versions of artwork in 2010. He said this reproduction was his most difficult project because the couple’s robes are so detailed (精细的).
Dominika Raditsch is a blind museum visitor. She touched the reproduction. As she moved her hands around it, she said, “Exactly, can you see these? There are so many details.” Raditsch said she can imagine what the original painting looks like when she touches the reproduction. “It’s somehow round. You can feel it. It comes with it. And in many places it’s so smooth. And then I think to myself: it probably shines too!” Raditsch said.
The Belvedere is not the only museum to have 3-D versions of its artwork. Some of the pieces at the Prado, in Madrid, Spain, have reproductions that can be touched. But the piece in Vienna has one special part: it is made with widely available 3-D printing technology. That means one day, blind art fans anywhere in the world could download the source files and print the reproductions themselves.
【1】What is “The Kiss”?
A．A European Union project.
B．A popular painting
C．A 3-D technology.
D．A famous museum.
【2】Why did Reichinger say this reproduction was difficult to finish?
A．The painting was reproduced detailedly.
B．The original artwork was made in 1908.
C．Blind art fans can’t download the source files.
D．The 3-D technology is not available.
【3】What is the best title for the text?
A．A European Union Program for Museum Visitors
B．How to Reproduce the World-famous Paintings
C．A Special Museum for Art Fans in Vienna, Austria
D．3-D Printing Lets the Blind Experience Famous Paintings
28、Famous Israeli gastronome (美食家) Michal Ansky is a professional taster and a Master Chef judge. So when she was invited to the world’s first public blind taste test setting lab-grown chicken into competition against a conventionally raised product, she was confident that she would be able to tell the difference.
Surrounded by cameras at a restaurant bar, she tasted from two dishes, labeled A and B. A team of lawyers looked on, tasked with making sure that the tasting truly was blind. Even the chef who sautéed (嫩煎) the meat in sunflower oil—no salt, no seasonings—didn’t know which was which. Both were flavorless, Ansky noted, but she would bet her reputation that sample A was the real thing. It had a richer, more “chickeny” taste.
The tasting was hosted by a meat-tech startup SuperMeat at its in-house restaurant, The Chicken. Ever since 2013, when the first lab-grown hamburger was presented to the public with a $330,000 price tag, alternative-meat companies have been inching closer to a product that is just as tasty and nearly as affordable as the real thing, but without the climate impacts. One new study found high-income countries could cut agricultural emissions (排放物) by almost two-thirds by moving away from animal-based foods.
But one question remains: Would consumers be able to tell the difference? SuperMeat decided to put its product to the test without the deep frying and sauces that are usually used to mask a lack of flavor. Sample B had less flavor, so Ansky reasoned that it had to be the one grown in a lab. She was so convinced of her decision that when SuperMeat founder Ido Savir announced that it was in fact A that was lab-grown, she corrected him. “No,” she said. “A is the real chicken.”
A day later, I spoke to Ansky about the tasting. “It’s one of the only times in my life that I’m really happy that I was wrong,” she admitted.
【1】What do we know about the taste test?
A．It was hosted by a chicken-themed restaurant.
B．Food samples were made with different flavors.
C．Michal Ansky was invited to the test for her reputation.
D．Lawyers were involved to ensure the authority of the activity.
【2】The purpose of hosting the taste test is to prove that ________.
A．lab-grown chicken tastes as good as raised chicken
B．meat eaters turn a blind eye to the taste of chicken
C．even a world-famous gastronome can make mistakes
D．chicken should be cooked well to appeal to customers
【3】What is the biggest advantage of lab-grown chicken?
A．More chickeny taste.
B．More affordable price.
C．Less artificial flavor.
D．Less carbon footprint.
【4】Why did Ansky say that she was happy that she was wrong?
A．She wanted to ease her embarrassment.
B．She saw a milestone in the food industry.
C．She changed people’s opinion of her job.
D．She believed in the power of making mistakes.
29、Why Is 2020 Called a Leap Year?
February 29 comes up on the calendar only every four years. A year with a February 29 might be good news if you are paid by the day or the week. But it might be bad news if you were born on a February 29.【1】.
American English has a term for the unusual situation. February 29 is called a leap day. And the entire 12-month period with a February 29 in it is called a leap year. This year, 2020, is such a year.
In a leap year, the dates jump over one day of the week. Let me explain. In 2017, the last day of the year, December 31, fell on a Sunday. In 2018, it fell on a Monday. In 2019, it fell on a Tuesday. But in 2020, December 31 will fall on a Thursday.【2】.
The reason for a leap day or a leap year is because our calendar does not follow the Earth’s orbit around the sun exactly.【3】. So every four years, we put all that time together into an extra day — or, what is officially called an intercalary(闰) day.
“Leap” is also an important word for two other common American expressions.【4】. If you want someone to investigate a situation completely before taking action, you might say, “Look before you leap.” The other expression is a phrase of hope. Urging someone to “take a leap of faith” means inviting the person to take action, even if not everything about a situation is known. Interestingly, both phrases are completely reasonable to say to someone who is about to get married. On that note, some people choose to marry on February 29 because it is an unusual date.【5】. Leap years were believed to be difficult, and leap days unlucky and a bad time to begin anything new. Whatever you think about them, the change in the calendar will be gone soon enough. Then we can return to normal, and leap over February 29 as usual.
A．One is a kind of warning.
B．That’s why we called it a Leap Year
C．It just leaped right over Wednesday.
D．Each year, we have a little time left over.
E．You have to wait three years in between birthdays!
F．As a verb, the word “leap” means to jump, or to move quickly.
G．Some ancient peoples would likely tell couples not to do it, however.
30、Crowdfunding (众筹) campaigns to help people with cancer pay for ineffective alternative treatments are becoming more common. They often come with six-figure targets to meet the cost of debatable therapies. ________, headlines are almost guaranteed.
The BMJ (British Medical Journal) reports ________ over this, based on information I gathered working for the charity Good Thinking. By sorting fundraising sites like JustGiving and GoFundMe, I identified appeals from people in the UK who sought money for unproven or disproven treatments, finding 400 in the past three years. Those have raised £7 million, the money destined for ________clinics.
Although the treatments, such as extreme diets, aren’t backed by scientific evidence, people who are desperate and vulnerable are often ________by remarkable testimonials(证明书) provided by the clinics themselves. However, for those who see such stories in the media, and who care about following good scientific evidence, the natural reaction is to try to ________people from possible physical, emotional and financial harm.
________ these appeals isn’t easy. People with cancer often view these therapies as ________, and their supporters don’t want to consider that their efforts to help may cause harm.
However, journalists must review the role they play in promoting the ________. Their influence is powerful. As I sorted through appeals and the heartbreaking stories of desperately ill people, I was ________ by just how many cited success stories they had read in newspapers as their reason for trusting questionable treatments.
Most concerning of all were the frequent cases where someone had died—sometimes just months after eye-catching ________of their treatment. While the uplifting story of a community helping fund someone’s “cure” is attractive, the subsequent reality when that hope proves fruitless seems far less ________.
This leaves the public with a ________ view of the effectiveness of such treatments, and serves as an advertising tool for clinics which, under UK law, wouldn’t be able to directly promote their therapies.
If journalists wish to avoid promoting ineffective treatments, they would do well to view such stories not just as human-interest ones, but as ________ and health stories. This means ________the evidence behind treatments, seeking expert opinion on their efficacy, and choosing not to run stories that fail such a careful examination.
I’m certain no journalist would want their work to be used as a recruitment tool for therapists whose treatments offer nothing but heartbreak and false hope, yet until reports of miraculous cancer cures in questionable clinics are approached with an appropriate level of skepticism(怀疑), I fear such places will continue to ________.

34、Directions: Read the following passage. Fill in the blanks to make the passage coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word. For the other blanks, use one word that best fits each blank.
My daughter
(A story told by a father, a famous actor)
My wife and I only had the one child. We had Amy.
I see her as my best friend. I think she’d always come to me first if she had a problem. We have the same sense of humor, and share interests. 【1】 I don’t mind animals, she’s completely fascinated with them, and she has always had dogs, cats, horses, and goldfish in her life.
We were 【2】 (close) when she was about four, which I think is a lovely age for a child. They know the parents best, and don’t have outside contacts. She must have grown up suddenly when she went to school, because I remember her growing away from her family slightly. Any father who has a teenager daughter comes across an extraordinary collection of people, and there seemed to be an endless stream of strange young men 【3】 (come) through our house. By the time I learned their names they 【4】 (go) away and I had to start learning a new lot.
I wanted more than anything else for her to be happy in 【5】 she was doing, and I was prepared to pull strings to help her on her way. When she left a good school she decided she wanted to become an actress so I got her into drama school. It wasn’t to her liking so she joined a theatre group and began doing bits and pieces in films. She was doing well, but then gave it up. She probably found it boring. Then she took up social work, and finally went to work 【6】a designer and he became her husband. And that’s really the story of her life. She must be happy with him—they’re always together.
We have such similar tastes in books and music 【7】 I used to take her to see an opera, which is my big passion. However, I don’t think she likes it very much. She doesn’t come with me anymore.
I don’t think she’s a big television watcher. She knows when I’m on the television, and she 【8】 watch, but I don’t know. It’s not the kind of thing she tells me.
We’re very grateful for Amy. She’s a good daughter as daughters go. We’re looking forward to being grandparents.
35、Directions: Complete the following passages by using the words in the box. Each word can be used only once. Note that there is one word more than you need.
Tablets are really useful devices, but their big screens always make them a burden to carry around without a bag. Wouldn’t it be great if there were a phone with the powers of a tablet that could be folded up and fit 【1】 into the hand?
Now something like a tablet-shaped but fold-able phone is about to become 【2】. In February, South Korean electronics company Samsung and China’s Huawei both unveiled fold-able phones Galaxy Fold and Huawei Mate X 【3】. Mobile phone use has entered the “fold-able future”, The Verge noted.
The technology could change our lives in significant ways. These devices, due to their 【4】 screens, give us the larger screens we want. Meanwhile, they still fit easily into the pocket. As USA Today noted, they’re “the 【5】 of a small tablets and smart-phone, all in a single device”.
The technology could 【6】 other devices too. For example, we could make TVs that stick to walls like posters, or fold up easily to hide away in drawers. In crowded modem cities, they will help us to 【7】 available space.
In a keynote address, Samsung’s senior vice president of mobile product marketing, Justin Denison, called the fold-able screen “the 【8】 for the smart-phone of tomorrow.” “It’s a balank canvas for us to do something beautiful together,” he said.
So is there nothing to stand in the way of the fold-able future?
According to tech news website Android authority, the necessary displays were difficult to produce. In 2012, nine out of every to OLED screens produced were 【9】. Today, that 10 percent rate has been improved to between 50 and 90 percent. However, at present these fold-able devices are expensive. For example, the price of Huawei Mate X is 17,500 RMB. That’s a price that may 【10】 the majority of people.
But if the fold-able device isn’t going to change the world overnight, there is no doubt that it is coming.
Patrick Moor-head, an industry analyst told The Verge, “Few are debating if fold-able or roll-able mobile displays are the future of smart-phones; the only question is when and by whom.”
36、Directions: Complete the following sentences by using the proper form of the words or expressions given in the frame. Each one can only be used once.
Why your Password May Not Be As Safe As It Seems? Does “qaz2ws” strike you as a nice safe password? What about “adgjmptw”? An analysis has found them to be among the passwords that are most 【1】 used, which of course means they are not secure at all.
When ten million passwords were leaked on to the internet，they appeared to 【2】that attempts by internet security experts to make us improve our password strength had been successful, even if, in the specific case of the leaked passwords, they are also completely pointless.
While many of the passwords were still single words, such as “password”，there was also a clear attempt by many to make them harder to【3】. The problem was that people seemed to do so in the same way.
“Users are becoming slightly more 【4】what makes a password strong,” explained WP Engine, an internet company that performed the analysis. “For instance, adding a number or two at the end of a text phrase. That makes it better, right?”
But 【5】no. They found that almost half a million passwords did this and in 20 percent of those all people did was put the number “1” at the end.
Perhaps this is why some companies are now trying to move gradually beyond passwords. Yahoo! is giving users the option to 【6】 their mobile phone with an account, having a single use passwords texted to it each time they want to log on.
Although the serviced is voluntary, Dylan Casey an executive at Yahoo!，said that it was “the first step to【7】passwords”. He said it was a(n)【8】that it was increasingly hard for people to remember all the passwords they had. “I don’t think we, as an industry, have done a good enough job of putting ourselves in the shoes of the people using our products,” he said.
It would certainly be a more sensible strategy than same people’s improving upon “password” by using “password” or，“tran5p053d numb3r5 f0r 133tr3r5”.
“We are, for the most part，predictably【9】when it comes to choosing passwords, despite a decade of warnings from password strength checkers during sign-ups” said WP Engine. “We love taking a(n) 【10】, and so do password crackers.
37、Directions: Complete the following passage by using the words in the box. Each word can only be used once. Note that there is one word more than you need.
Driving an electric car 【1】 to the protection of environment, or so the marketing departments of their makers would have you believe. Yet a report which analyzes car emissions presents a rather different picture. A battery-powered car recharged with 【2】 generated by coal-fired power stations, it found, is likely to be more harmful. It could cause more than three times as many deaths from pollution as a 【3】 petrol-driven vehicle.
The study was carried out by the University of Minnesota. The researchers estimated how levels of fine particulate matter (细颗粒物) and ground-level ozone — two important 【4】 of air pollution — would change when a car is powered by different ways.
It was no surprise that electric cars whose batteries were recharged with power from wind, solar or hydro-electric sources came out to be virtually free from harmful 【5】. They were estimated to cause 231 deaths over the course of a year, compared with 878 for petrol cars. Electric cars recharged with power from natural gas-fired stations were also a lot less harmful than petrol-driven ones, with 439 deaths. But if those same electric cars were recharged 【6】 by coal, they would be responsible for over 3,000 deaths.
Biofuels also caused more health problems than petrol. But diesel, which often 【7】 concern about pollution, is slightly cleaner than petrol. This is because the study assumes for all cars that emission-control technologies will be more widely used, especially particulate filters which have a remarkable effect on cleaning diesel 【8】. Diesel cars are also more 【9】 of fuel than petrol-driven ones.
Overall, the study shows that electric cars are cleaner than those traditional vehicles only if the power used to charge then is also clean. That is hardly a surprise, but the 【10】 of the difference is. How green electric cars really are, then, will depend mainly on where they are driven. In France, which obtains more than half of its power from nuclear station, electric cars look like a good bet. In China and some other developing countries, where a large amount of electricity is produced from coal, they may not be so environment- friendly as they are marketed.
38、阅读下面短文，根据其内容写一篇60词左右的内容概要。
Artificial intelligence(AI)teachers can provide customized teaching for students to meet their unique requirements through analyzing data and deep learning.In the future, they may replace human teachers for basic teaching tasks.Since some students may find it and put new power into traditional teaching patterns.An educational system providing customized teaching centered on students represents the future trend of AI education.
China's AI education has developed rapidly in recent years with the rise of several thousand relevant companies.Currently,AI teachers are able to help students leamn pronunciation,analyze their condition,guide them to learn independently,and even grade writing assignments. Some foreign AI educational systems have been introduced into several domestic schools and have worked well on trial.
However,the promotion of AI education is still facing several difficulties in practice such as low technological levels,inadequacy of data and lack of funds.AI education still depends largely on human teachers' work.Most importantly,it conflicts with current educational patterns because the courses developed by foreign countries are not suitable for Chinese exam-oriented education.Teachers may also find it hard to change their original roles in classrooms since easing control on classes may make them seem irresponsible.These problems need to be handled before the mass promotion of Al education.
With AI teachers,the original teacher-centered classes will be transformed into student-centered ones where teachers only organize the class and provide guidance.Since teachers are supposed to not only equip students with knowledge but also shape their values and help them develop creative abilities,AI teachers will not replace human teachers but will only pose higher requirements of teaching.A combination of AI teachers and human ones can create the best future for Al education.
