26、As Valentine’s Day approaches, many people with dogs will not care one bit whether they get a card. A survey by the Kennel Club has found almost one in five said they were so attached to their pet because “dogs don’t let you down” in the same way that other people might.
Hollywood legend Glenn Close took her Havanese dog Pip to the Oscars last year, describing her pet as “the best date a girl can have”. Comedian Miranda Hart and racing driver Lewis Hamilton have gone on holiday with their dogs, and actor Ryan Gosling has taken his cross-breed George, who he describes as “the great love of my life”, on to chat shows for moral support.
This could be due to the numerous benefits that come with dog ownership — from the psychological to the physical. Dogs help their owners unwind, whether that’s with a daily walk in fresh air, or with a cuddle(依偎) on a sofa. They can also be great listeners, help their owners release stress, and can play a part in improving their health and fitness.
Nevertheless, for those dog owners who are still looking for love, the research suggests their pet might help. More than a fifth of those questioned said they had been asked out on a date with their dog appearing best for attracting a potential partner. Among those responding to the survey, 21 percent said they were more likely to date someone who also had a dog.
Mr. Lambert, a spokesman for the Kennel Club, said, “This is quite unsurprising when you consider that dogs are a great ice-breaker, when strangers may otherwise not look twice at each other, and that we tend to have more associations about people who love dogs.”
People who owned a pet dog were also very likely to say their pet may have helped them out romantically.
【1】What does the author intend to do in paragraph 2?
A.Summarize the previous paragraph.
B.Provide some advice for the pet owners.
C.Introduce some celebrities to the readers.
D.Give some examples to support the view above.
【2】What does the underlined word “unwind” in paragraph 3 probably mean?
A.Focus.
B.Relax.
C.Recover.
D.Participate.
【3】Why is dating out with a pet dog more appealing?
A.Because a pet dog serves as a bridge between the parties.
B.Because a pet dog is the best friend of mankind.
C.Because a pet dog adds to romantic atmosphere.
D.Because a pet dog breaks the ice of a conversation.
【4】What is the author’s attitude to the company of a pet dog?
A.Doubtful.
B.Positive.
C.Disapproving.
D.Reserved.
27、What is a hero? We may think of the fictional characters with supernatural powers or great people who can influence world events. Now, as the nation continues its all-out efforts to fight against the novel coronavirus pneumonia(COVID-19), medical staff have become heroes in the eyes of the public.
As of Feb 19, a total of 32,000 medical staff outside Hubei province have been working to treat patients around the center of the outbreak.
Zhang Dingyu, the president of Wuhan Jinyintan Hospital, is one of these heroes. Since the hospital received the first seven patients in December, Zhang has been so busy that he barely gets any sleep. Even suffering from amyotrophic lateral sclerosis (肌萎缩侧索硬化), the 56-year-old doctor is doing his best to quicken his pace to save precious time for infected patients. “I have to run, racing against time to save more patients from the deadly disease, because I don’t have much time left in my life,” Zhang told Xinhua News Agency.
With the duty of saving lives, many medical professionals like Zhang have been working long hours for days, despite their fear and worries.
Lu Jingjing from Wuhan Children’s Hospital also works at a temporary mobile hospital. She does not let her parents know that she is now working with novel coronavirus-infected patients.
When her parents ask for a video chat, Lu says she is working and lets her husband and children chat with them instead.
“It’s dangerous but we should win the battle with the virus as soon as possible, so that medical staff and patients can go back home,” she told China Daily.
US writer Khalil Gibran (1883-1931) once wrote, “Tenderness and kindness are not signs of weakness and despair, but the manifestations of strength and resolution.” It’s true for the medical workers.
Everyone has fear, especially when it comes to deadly diseases. But for medical staff, saving lives comes first and is enough for them to be brave and stay on the front. They may look like ordinary people in daily life, but in these extraordinary times, they are heroes.
【1】What is the author’s main purpose in writing this article?
A.To explain what makes a modern-day hero.
B.To praise medical staff for their efforts to fight the NCP.
C.To describe what measures China has taken to deal with the virus.
D.To show the difficulties faced by medical staff treating NCP patients.
【2】What do we learn from Zhang Dingyu’s words?
A.His illness has turned him into an impatient man.
B.His illness makes him work without fear.
C.He feels sorry for himself because of his illness.
D.He wants to help as many patients as possible.
【3】Why doesn’t Lu Jingjing answer her parents’ video calls?
A.She is too busy and has no time for video chats.
B.She doesn’t want her parents to worry about her.
C.It’s not allowed to make a video call from the hospital.
D.There is no WiFi signal at the temporary mobile hospital.
【4】The underlined word “manifestations” in the second-to-last paragraph probably means “_______”.
A.results
B.differences
C.indications
D.advantages
28、 Implanted (植入的) devices, such as heart pacemakers, are a valuable part of modern medicine. Their use, however, is limited by the need to renew their batteries and this is a particular problem for those inside the wearer’s head. Therefore, a way to power such implants without replacing their batteries at all would thus be welcome. And Dr Hyuck Choo and his colleagues think they have one. They plan to collect the necessary energy from the vibrations(震动) that occur when someone is talking.
DrChoo’s power plants are small sheets of lead zirconate titanate, a material that produces electricity when it vibrates. He knew that sheets of the size he chose have a resonance (共振) at around 690Hz. This is well above the normal range of the human voice. Using larger sheets would lower the resonance frequency. So he sought to lower a sheet's resonance frequency without increasing its area by caring a special shape out of it. And it worked!
When Dr Choo and his colleagues tested the carved sheets by exposing them to a range of frequencies and monitoring the amount of electricity generated, they found that the voltage was between 100Hz and 120Hz (approximately the common frequencies of adult male vices), and also between 200Hz and 250Hz (the female voice s common frequencies). And, although the amount of power produced is not huge, it seems adequate for the task.
As Dr Choo reported at a conference on January 26, he and his team were able to harvest a tenth of a mill watt per square centimetre of lead zirconate titanate from the voice of a man talking at 70 decibels (分贝), which is normal speaking volume, and tents from someone shouting at 100 decibels Implants usually require a tenth of a mill watt or less to function so this suggests a practical device might be within reach-especially as the vibrations produced by the voice travel efficiently up through the skull, meaning the generator could be put into an implant.
【1】What limits the use of implanted devices?
A.The shape of the devices. B.The effect of the vibrations.
C.The need for continuous power. D.The difficulty in producing the battery
【2】What problem did Dr Choo have to solve in Paragraph 2?
A.To renew the batteries of the implants.
B.To make the resonance above the human voice.
C.To pick out suitable material for his power plants.
D.To ensure the resonance of the sheets fit in with the human voice.
【3】What does “the task” in Paragraph 3 refer to?
A.Exposing the sheet to sounds. B.Powering the implanted devices.
C.Lowering a sheet's resonance frequency. D.Monitoring the electricity produced.
【4】What can we learn from the last paragraph?
A.The voice powered device is likely to be available.
B.A man has to shout loudly when using the device.
C.The device will be put into production after the conference.
D.The generator should be put into the skull when used.
29、The Nobel Prize is considered one of the most recognizable and admirable awards possible, honoring people of the world for their outstanding achievements in different fields.
Alfred Nobel was born in 1833 to a family of engineers in Stockholm, Sweden. Nobel as a young man studied with Nikolai Zinin, a well-known chemist. In 1850, he met Ascanio Sobrero, the inventor of nitroglycerin (炸药) in Paris. Interested in its unpredictable nature of exploding under pressure or heat, Nobel started to find a way to control it and make a usable explosive(炸药). In 1857 he applied for his first patent (专利), an English patent for a gas meter. After years of efforts, in 1867, at the age of 34, Nobel invented dynamite(炸药), which is much easier and safer to control than nitroglycerin. Dynamite was an immediate business success and it was patented in the US and the UK and was widely used in mining.
During his lifetime, Nobel invented and patented various explosives. He built up his wealth from his 355 inventions, from which dynamite was the most important.
When Alfred’s brother Ludwig died in 1888, a French newspaper mistakenly published Alfred’s obituary (讣告). Reading his own obituary, Nobel was disappointed to find out his public image(形象). The newspaper strongly blamed(责备) Nobel for inventing dynamite, giving him the nickname of “the merchant of death” and saying “Dr. Alfred Nobel, who became rich by finding ways to kill more people faster than ever before, died yesterday.”
To Alfred, this obituary was a warning. He spent his lifetime alone inventing things and was deeply concerned with how he would be remembered. This unfortunate event inspired him to make changes in his will(遗嘱), so as to improve his public image, and to be remembered for a good cause.
In 1895, one year before his death, Nobel made the last will, saying clearly that his wealth would be used to create a series of prizes for those who have made great contributions to mankind in physics, chemistry, physiology or medicine, literature, and peace. To widespread astonishment, Dr. Alfred Nobel gave away 94% of his total wealth to found the five Nobel Prizes.
【1】According to paragraph 2, what led to Nobel’s outstanding achievements?
A.The valuable help from his family.
B.The strong desire to make money.
C.His lifetime dream of achieving success.
D.His great curiosity and devotion to science.
【2】What was Alfred Nobel’s attitude towards the newspaper’s obituary?
A.Upset.
B.Supportive
C.Optimistic
D.Satisfied
【3】Why did Nobel give away most of his wealth to set up the Nobel Foundation?
A.To publish his findings of scientific research.
B.To improve his public image.
C.To be remembered as the “Merchant of Death”.
D.To prove the importance of his inventions.

34、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.
On a broiling afternoon when the men were away at work and all the women napped, I moved through majestic depths of silences, silences so immense I could hear the corn 【1】. Under these silences there was a / an orchestra of natural music playing notes no city child would ever hear. A certain cackle from the henhouse meant we had gained an egg. The creak of a porch swing told of a momentary breeze blowing across my grandmother’s yard. As I 【2】 along a mossy bank to surprise a frog, a 【3】splash told me the quarry had spotted me and slipped into the stream. Wandering among the sleeping houses, I learned that tin roofs crackle under the power of the sun, and when I tired and came back to my grandmother’s house, I padded into her dark cool living room, lay 【4】 on the floor, and listened to the hypnotic beat of her pendulum clock on the wall ticking the meaningless hours away.
I was enjoying the luxuries of a rustic nineteenth-century boyhood, but for the women Morrisonville life had few 【5】. Their lives were hard, endless, dirty labor.
For baths, laundry, and dishwashing, they hauled buckets of water from a spring at the foot of a hill. To heat it, they chopped kindling to fire their wood stoves. They boiled laundry in tubs, scrubbed it on washboards until knuckles were 【6】, and wrung it out by hand. Ironing was a business of lifting heavy metal weights heated on the stove top.
They scrubbed floors on hands and knees, thrashed rugs with carpet beaters, killed and plucked their own chickens, baked bread and parties, grew and conned their won vegetables, patched the family’s clothing on treadle-operated sewing machines, 【7】before the men to start the stove for breakfast and pack lunch pails, polished the chimneys of kerosene lamps, and even found time to tend the flowers that grew around every house. By the end of a summer day a Morrisonville woman had toiled like a serf.
At sundown the men drifted back from the fields exhausted and 【8】. They scrubbed themselves in enamel basins and, when supper was eaten, climbed up onto the porch to watch the night arrive. Presently the women 【9】 them, and the twilight music of Morrisonville began.
The swing creaking , rocking chairs 【10】 on the porch planks, voices murmuring approval of the sagacity of Uncle Irvey as he quietly observed for probably the ten-thousandth time in his life, “A man works from sun to sun, but a woman’s work is never done.”
35、根据句意填空
In the USA, the Amish-a Christian group-are famous because they drive 【1】 instead of cars, do not use TVs or refrigerators, and do not have personal telephones. Many people assume the Amish must have 【2】 reasons for their many rules, but this is not true. In truth, whenever a new technology is introduced, the Amish meet and discuss its advantages and disadvantages. They then vote on whether they will accept it. The Amish 【3】 cars because they like having 【4】 communities where everyone lives close together. They have no TVs or refrigerators because their homes do not have electricity-they do not think it is necessary and 【5】 dealing with strangers, such as the people who work at the electric company.
36、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.

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.
