26、Windows are a key component in a building's design, but they are also the least energy- efficient part. According to a 2009 report by the United Nations, buildings account for 40 percent of global energy usage, and windows are responsible for half of that energy consumption. If conventional windows are used to better block sunlight passing into a building, they need expensive coatings. Even so, they can not adjust the indoor temperature effectively.
Scientists at the Nanyang Technological University, Singapore (NTU) have developed a smart liquid window panel that can help. By creating a mixture of micro-hydrogel (水凝胶), water, and a stabilizer, they found that it can effectively reduce energy consumption in a variety of climates. Thanks to the hydrogel, the mixture becomes hard-to-see- through when exposed to heat, thus blocking sunlight, and, when cool, it returns to its original clear state. The high heat capacity of water allows a large amount of heat energy to be stored instead of getting transferred through the glass and into the building during the hot daytime when office buildings mainly operate. The heat will then be gradually cooled and released at night when the staff are off duty.
As a proof of concept, the scientists conducted outdoor tests in hot (Singapore, Guangzhou) and cold (Beijing) environments. The Singapore test revealed that the smart liquid window had a lower temperature (50°C) during the hottest time of the day (noon) compared to a normal glass window (84°C), The Beijing tests showed that the room using the smart liquid window consumed 11 percent less energy to maintain the same temperature compared to the room with a normal glass window. They also measured when the highest value of stored heat energy of the day occurred. This "temperature peak" in the normal glass window was 2 pm, and in the smart liquid window was shifted to 3 pm. If this temperature peak shift leads to a shift in the time when a building needs to draw on electrical power to cool or warm the building, it should result in lower energy charges for users. The research team is seeking ways to cut down the cost of producing the smart window and so far, they have found several industry partners to commercialize it.
【1】What is the disadvantage of conventional windows?
A．They are expensive.
B．They are not heatproof.
C．They contribute less to energy saving.
D．They can't block light into the building.
【2】How does a smart liquid window panel work to cool buildings?
A．By taking in much of heat energy.
B．By returning to its original clear state.
C．By getting most of sunlight transferred.
D．By spreading sunlight in different directions.
【3】According to paragraph 3, what is the value of the temperature peak shift?
A．It will make the windows long-lasting.
B．It could help the building users reduce costs.
C．It makes the buildings rely on no electrical power.
D．It helps the windows maintain a constant temperature.
【4】What can we expect of the smart window in the future?
A．It will be unaffordable.
B．It needs to be further improved.
C．It will be widely used in the city.
D．It will come onto the market soon.
27、The 3D-printing industry is accelerating its efforts to help fight the new coronavirus and the disease it causes, COVID-19.
On Tuesday, HP announced it’s working with those who bought its 3D printers to make medical face shields, hands-free door openers and an adjuster for face masks for medical staff who often must wear them for hours. It’s also testing “hospital-grade” face masks meeting the higher-end FFP3 (过滤式面罩) standard and parts for simple emergency ventilators (呼吸机) and it’s looking into nasal swabs to test for COVID-19 infection. HP also is offering free downloads of its 3D-printed medical equipment designs.
Carbon, whose 3D printers are used to make everything from bicycle seats to teeth straighteners, said it plans to send face shield designs to its network of customers who’ve bought its 3D printers. Carbon co-founder and Executive Chairman Joseph DeSimone said on Monday the company expects to send the designs by early Tuesday.
3D-printcr makers typically sell their products to others that actually do the 3D printing. One such customer, Ford, said Tuesday that it’s made 1,000 face shields and shipped them to Michigan hospitals, with plans to make 100,000 face shields a week. It is also working with 3M and General Electric on respirator masks and ventilator designs.
The effort is one of several to apply 3D-printing technology to the fight against coronavirus. 3D printing isn’t as fast at churning out products as conventional mass production methods. But 3D printers are flexible and able to make many different parts anywhere there’s a printer and raw materials like the plastic resins Carbon printers use.
Some 3D-printing efforts have focused on ventilators, which expected to be in short supply with a surge of COVID-19 patients suffering from respiratory (呼吸器官) problems. Also in short supply are N95 masks that can be useful in reducing the likelihood a wearer will spread COVID-19 to others.
Carbon’s DeSimone is cautious about the enthusiasm, though, saying that regulatory approval is important and that 3D-printcr enthusiasts shouldn’t be making components not intended for close human contact that might release unhealthy gases.
【1】What is the passage mainly about?
A．An introduction about 3D-printing.
B．The 3D-printing industry’s efforts to help fight COVID-19.
C．The products that 3D-printing makers sell.
D．How 3D-printing makers produce medical equipment.
【2】HP announced to help its customers to make the following products except for_____________.
A．medical face shields
B．hands-free door openers
C．an adjuster for face masks
D．emergency ventilators
【3】Which of the following is true according to the passage?
A．Carbon’s company will finish its design after Tuesday.
B．Ford has made 1,000 face shields end plans to make 10,000 more in a week.
C．3D printers are more flexible than traditional mass production methods.
D．Most 3D-printings focus on making ventilators and N95 because of their short supply.
【4】What can be inferred from the last paragraph?
A．3D-printing may release unhealthy gases.
B．DeSimone is cautious about 3D-printing.
C．Carbon’s company didn’t gain regulatory approval of making medical equipment.
D．3D printers aren’t enthusiastic about making components designed for close human contact.
28、On June 12,1942,Anne Frank’s parents gave her a small diary for her 13th birthday.She and her family had been living in Amsterdam for nine years after fleeing their native country in 1933.They could not escape the influence of the war sweeping across Europe.
On July 6,1942,her family was forced to go into hiding.For the next two years,Anne put down her innermost thoughts and feelings to her diary.Her reports of daily life painted a picture of a bright girl.She described her love of writing and her desire to make a career of it one day,saying,“I want to be useful or bring enjoyment to all people,even those I’ve never met.I want to go on living even after my death.”
She got her wish far too soon.Her diary came to an abrupt end in August of 1944,when she and others hiding in the“Secret Annex”were discovered,arrested,and sent to prison.Tragically,Anne,her sister and her mother,all died there.
Her father,Otto,the only survivor among those who hid in Annex,returned to Amsterdam after the war.He was deeply moved by his daughter’descriptions of life in Annex and her feelings about her family and other residents.He devoted the rest of his life to sharing her story with the world so that the same tragedy that happened to his family might never be repeated.Through her courage,her hope,and her unshakable faith in the goodness of people,her short life left a long legacy(遗产),touching and inspiring generation after generation of people she never met.
I would never forget visiting the Anne Frank House when I was just 23 and thought that I had already been alive eight years longer than she had been.Like millions of people moved by Anne Frank’s story,I have tried my best since then to live my life.We all would do well to remember the wisdom of a young girl who taught us that our differences make life more interesting,but our common men matter more.

29、Laurie Horam never thought of himself as musical. At home, his dad never listened to music, while one of his boarding school teachers labelled him tone deaf. But last month he started to busk. And while he accompanies on harmonica (口琴) his guitar - playing friend Alan Eaton, people clap, dance and throw coins into Alan’s guitar case for the local food bank. Horam caught himself thinking: “How, at the age of 80, do I come to be playing music to people on the streets of Brad-ford?”
The question preoccupied him, because, some years ago at a family gathering, Gavin, one of his children, said, “You know what, Dad? It can’t be coincidental. We must have got our natural abilities and interest from you.” He has three sons, two daughters and a stepson from two marriages; between them, they cover a range of instruments and genres from techno to rock. Horam was floored. “There can’t be music in me, because I can’t play!”, he said.
Eight years ago, Horam, a retired civil servant, was driving back from a trip to the Yorkshire coast with his eldest son, Gavin, who was visiting from Canada. Cavin wanted to stop at a music shop. He walked out and said, “Here you are. I bought this for you, Dad. It’s a harmonica. I’ll try to show you how to play a bit.”
They went to a local pub. Gavin played guitar and Laurie sat in the corner with his harmonica, trying to make a sound that no one would hear. After six months, he was invited into the group. Unable to read music, he discovered a talent for improvisation (即兴表演), responding to a note within a millisecond without batting an eyelid. “I don’t play by ear. I play by heart.” Actually, Horam says, “My harmonica plays me - how I feel, what I am, what I’ve been.”
Music has enriched life with friendship and made Horam feel “part of something much bigger” than himself. “At a time when the scope of life might be shrinking, mine is expanding,” he says. “Maybe we never know completely who we are or what we can do.”
【1】Why did Horam play the harmonica on the streets of Bradford?
A．To collect money for charity.
B．To recall the good old days.
C．To live his childhood dream.
D．To beg food from passers-by.
【2】What’s the common feature of Horam’s children?
A．They are all divorced.
B．They are all tone deaf.
C．They are all musical.
D．They are all guitar players.
【3】What is Gavin’s attitude to his father’s musical ability?
A．Unclear.
B．Positive.
C．Doubtful.
D．Disapproving.
【4】What can be learned from the last two paragraphs?
A．Music fails to help Horam express himself.
B．Music helps Horam lead a comfortable life.
C．Music helps Horam sharpen his own hearing.
D．Music brings Horam a broader circle of life.

34、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.”
35、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.

Why Cold weather Causes So many Flight Cancellation?
Each year, about 60,000 flights get canceled because of bad winter weather, which costs airlines and airports an estimated $3 billion. But it’s not the freezing cold temperatures that cause problems for planes. After all, 【1】 jets fly 10 kilometers up, where temperatures hover around -50 degrees Celsius.
In fact, planes 【2】 in cold weather, since cold air is denser and leads to better thrust. Clearly, the real problem isn’t what’s going on up there. It’s what’s happening on the ground.
When a 【3】 polar vortex (极地涡旋) struck the Midwestern US in January 2019, temperatures dropped to -40 degrees Celsius and airline canceled 3,000 flights nationwide. In these situations, when temperatures start 【4】, everything slows down. Cargo doors can freeze up, along with the nozzles that pump fuel into planes, which delays the 【5】 process.
Even the plane itself can freeze over. Just a quarter-inch - thick layer of ice on a plane can disrupt the way air flows over its wings.
Les Westbrooks: The number one reason, I would say, that the reason flights get delayed in cold weather is going to be because there’s some kind of frozen precipitation, from frost to snow to a sheet of ice, adhering to the aircraft, adhering to the wings of the aircraft 【6】.
That’s Les Westbrooks, a retired airline pilot and an associate professor of aeronautical science at Embry-Riddle Aeronautical University. He says that 【7】, these planes are “de-iced” - but this also delays takeoff. The crew can spray the plane with a special hot water/ glycol mixture. It can take around 40 minutes to de-ice large passenger airplanes, so planes often have to wait “their turn” for the de-icing station, which, of course, can trigger more delays.
And ice on the runway, of course, creates another set of 【8】. In 2014, a plane at JFK skidded off an icy runway and into a mound of snow, leading to an hours-long shutdown at the airport. And even though crews can remove ice from the runway, scraping it off the pavement can lead to potholes (坑洞) and other 【9】, which makes takeoffs and landings more dangerous. And of course, snow and freezing rain on the ground can affect visibility to the point where officials have to decide it’s not safe to fly at all.
But if ice and snow aren’t the problem in these extremely cold temperatures, it’s usually another factor: people.
Les Westbrooks: The airplane flies at high altitudes, -60 degrees. It’s made to do that. Humans are not made to be outside in -60 degrees weather. And so the human factor becomes a big, big factor, when it becomes extremely cold.
Baggage handlers, aircraft fuelers, and mechanics all have to stay warm. Some airports, like O’Hare in Chicago, set up heated shelters for their employees. Of course, with everyone taking breaks to warm up, not as much gets done, which leads to even more delays and cancellations. Passengers start missing their 【10】 flights, and that, along with passengers who can’t make it to the airport due to bad road conditions, leads to half-empty planes.
In fact, many airlines might preemptively cancel flights before bad weather even hits. So, in the end, you can still blame cold weather for cancelling your flight.
