26、My father loves his garden. He planted some seeds in it. But at that time, I didn’t understand why working in the dirt excited him so much.
Unfortunately, in early May, my father was seriously injured in an accident. He had to stay in bed for a while. My mother had several business trips, so she couldn’t take care of the garden. I didn’t want my father to worry, so I said that I would take care of his garden until he recovered. I assumed that the little plants would continue to grow as long as they had water, and luckily it rained fairly often, so I didn’t think much about the garden.
One Saturday morning, my father said to me, “Christine, the vegetables should be about ready to be picked. Let’s have a salad today!” I went out to the garden and was upset to see that many of the lettuce leaves and carrots had been half eaten by bugs. There were hundreds of bugs all over them!
I panicked for a moment but then I quietly went to the nearest store to buy some vegetables.
When I gave the salad to him, he said, “Oh, Christine, what a beautiful salad! I can’t believe the carrots are this big already. You must be taking very good care of my garden.” I felt a little bit guilty.
Coming home, my mother saw the bag from the supermarket in the kitchen. I was embarrassed and I admitted, “Dad wanted a salad, but the garden was a disaster. I didn’t want to disappoint him, so I went to the store.” She laughed but promised to help me in the garden and weeks later I was finally able to pick some.
I carefully made a salad and took it to my father. He looked at it with a hint of a smile. “Christine, the carrots are smaller in this salad, but they taste better.”
Now, I better understand how putting a lot of effort into caring for something can help you appreciate the results more, however small they may be. Perhaps this was one of the reasons for my father’s love of gardening.
【1】Why did Christine originally promise she would do the gardening?
A．She was asked by her father to do it.
B．She was interested in growing vegetables.
C．She knew it was important to her father.
D．She wanted to improve her gardening skills.
【2】Which of the following was a problem in the garden?
A．Insects destroyed the lettuce and carrots.
B．Animals often dug holes in the garden.
C．The plants were given too much water.
D．The vegetables were marked incorrectly.
【3】Why could Christine secretly make the salad from store-bought vegetables?
A．Her mother helped her to buy the vegetables.
B．Her mother regularly helped her to make a spray.
C．Her father couldn’t see the garden’s progress.
D．Her father went on a business trip at that time.
【4】What did Christine learn through her experience of gardening?
A．Always get ready for a rainy day.
B．Don’t be disappointed by bugs.
C．Working alone produces results.
D．Hard work can often be rewarding.

28、 What does it take to be a good neighbor? Over the years I have had all kinds of neighbors, ones that were enjoyable and others that were to be avoided at all costs.
One of the most important things in being a good neighbor is to respect a person’s privacy(隐私).When someone new moves into the neighborhood it is a good idea to watch them to see how friendly you should be. If you go rushing over as soon as they move in they may think you are going to be one of those neighbors that come over at all times of the day, not respecting their privacy.
It is a good idea always to be friendly to everyone in the neighborhood. This can not only put you on good terms with them, but will also be a form of protection for your family and home. If you wave as they drive by or offer a friendly hello while they are out in their yard this shows that you respect them. If you are friendly to them they are much more likely to watch out for any wrong doings going on around your home while you are out and let you know if anything happens.
Another way of being a good neighbor is to be helpful in times of need. If you see that they are in need of a helping hand doing something or in times of a disaster, it is good to offer your help. Even though you have never really talked to the people down the street, they are willing to take the time to help out a neighbor in need.
In conclusion, if you respect a person’s privacy, treat them kindly and be helpful when you see they are in need, you will be a great neighbor and anyone would be happy to have you next door!
【1】When someone moves into your neighborhood you should_______.
A. visit them frequently B. know their privacy
C. respect them always D. avoid meeting them
【2】If you are always friendly to your neighbors you can________.
A. keep your family safe B. often visit their yard
C. make friends with them D. have your own privacy
【3】In the opinion of the author, neighbors should always be_______.
A. helpful, strong and kind B. respectful, friendly and helpful
C. honest, active and friendly D. polite, honest and kind
【4】The author develops the passage based on his_______.
A. wide knowledge B. scientific experiments
C. careful research D. real experiences
29、Scientists have developed a new type of smart bandage (绷带) that can signal the type of bacterial (细菌的) infection it’s protecting, just like a traffic light, as well as release the right type of drugs on demand. The traffic light system works just like this: Green means no bacteria or a low concentration of bacteria, yellow means drug-sensitive (DS) bacteria responsive to standard antibiotics (抗生素) and causes antibiotic release, and red means drug-resistant (DR) bacteria that need extra help to be wiped out.
In testing the bandage on mice, the research team was able to successfully treat both DS and DR infections using the new method. However, the common methods of sensing resistance are limited by time, the requirement for professional personnel, and expensive instruments. Moreover, the abuse of antibiotics causes the accelerated process of bacterial resistance.
It’s easy to see how a simple bandage and light could overcome some of these limitations. Treatment doesn’t have to wait for a doctor to make a diagnosis, and the bandage can get the right sort of drugs applied at the earliest opportunity. What’s more, the person wearing the bandage gets real-time feedback on what’s happening with the infection, if there’s an infection at all. The researchers say it offers numerous benefits over existing treatments that make use of light, including photodynamic therapy or PDT.
We’ve been seeing quite a few upgrades to the traditional bandage in recent years, thanks to advances in science — like the nanofiber mesh that attracts bacteria and draws some of it out, speeding up the healing process. Then there’s the novel bandage for treating burns, which stops bacteria from multiplying and lowers the risk of infection.
The more work that a bandage can do while it’s protecting a wound, the better. Efforts to improve bandages continue and now we've got a bandage that not only releases antibiotics, but also tells the patient exactly what’s going on too.
【1】What is the smart bandage mainly designed to do?
A．Avoid the use of antibiotics.
B．Clear out harmful bacteria.
C．Detect bacterial infections.
D．Increase treatment options.
【2】What is the advantage of the smart bandage?
A．It saves much time and cost.
B．It removes the risk of infection.
C．It prevents the bacterial resistance.
D．It improves doctor-patient relationship.
【3】What can be inferred from the last two paragraphs?
A．Traditional bandages are out of use now.
B．More smart bandages will be developed.
C．Progress in science calls for more research.
D．People are urged to study medical science.
【4】What does the text focus on?
A．A successful test on mice.
B．A colour-changing bandage.
C．Sensing drug-resistant bacteria.
D．Preventing abuse of antibiotics.

34、阅读下面材料，在空白处填入适当的内容(1个单词)或括号内单词的正确形式。
Smell the flowers before you go to sleep and you may just end up with rosy dreams. Have a whiff of rotten(腐烂的)eggs during the night and your dreams may be【1】(pleasant). So says researcher Dr. Boris Stuck, 【2】invited sleeping volunteers to a rose vs. rotten egg test in the University Hospital Mannheim in Germany. The subjects didn’t dream about roses【3】eggs, but rather he found that what they smelt affected the emotions of【4】(they) dreams.
And if you think【5】(smell) have a say in dreams, wait for what TV tells us. A UK study reveals that people exposed【6】black-and-white film and TV in their youth are to have monochromic(单色的)dreams throughout their life more【7】(probable). Eva Murzyn from the University of Dundee tested two age groups— one half 【8】(age) over 55 and【9】other half under 25.
The result? Under 5% of the dreams of the under-25s were in black and white. 【10】(watch)color TV in childhood seems to be the reason why.
35、Directions：Fill in each blank with a proper word chosen from the box. Each word can only be used once. Note that there is one word more than you need.
A huge milestone has just been reached in the field of artificial intelligence: AlphaGo, a program developed by Google’s DeepMind unit, has defeated legendary Go player Lee Se-dol in the first of five historic matches being held in Seoul, South Korea. Lee 【1】 after about three and a half hours, with 28 minutes and 28 seconds remaining on his clock. The series is the first time a professional 9-dan Go player has taken on a computer, and Lee is 【2】 for a $1 million prize.
“I was very surprised,”said Lee after the match.“I didn’t expect to lose. But I didn’t think AlphaGo would play the game in such a perfect manner.”DeepMind founder Demis Hassabis expressed“huge 【3】 for Lee Se-dol and his amazing skills.”calling the game“hugely exciting”and“very tense.”Team lead David Silver said it was an“amazing game of Go that really pushed AlphaGo to its 【4】.”
Go is an ancient Chinese board game that has long been considered one of the great 【5】faced by AI. While computer programs ow best the world’s leading human players of games like checkers and chess, the high level of intuition and 【6】required by Go has made it tough for computers to crack. DeepMind’s AlphaGo program is the most 【7】effort yet, using a complex system of deep neural networks and machine learning; it beat European champion Fan Hui last year, but Lee Se-dol is another 【8】 rival entirely.
“I don’t regret accepting this challenge,”said Lee.“I am in shock, I admit that, but what’s done is done. I enjoyed this game and look forward to the next. I think I failed on the opening layout so if I do a better job on the opening aspect I think I will be able to increase my 【9】 of winning.”Lee was surprised both by how strong AlphaGo’s opening was, and by some 【10】moves.

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.
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.
AI artwork sells for $432,500 — nearly 45 times its high【1】 — as Christie’s becomes the first auction house to offer a work of art created by an algorithm. This portrait, however, is not the product of a human mind. It was created by an【2】 intelligence, an algorithm defined by that algebraic formula with its many parentheses. And when it went under the【3】 in the Prints & Multiples sale at Christie’s on 23-25 October, Portrait of Edmond Belamy sold for an【4】 $432,500, signaling the arrival of AI art on the world auction stage.
From a distance, Portrait of Edmond de Belamy looks almost plausible. Up close, however, the paintwork becomes a grid of mechanical-looking dots, the man’s face a golden blur with black holes for eyes. Look into those eyes. They show no sign of feeling or life. Did a computer make this?
The answer is yes. The first artwork【5】 by AI to be sold at Christie’s, its【6】 price would seem to suggest that in future we will get computers to make art for us. Robot van Gogh will harmlessly cut its ear off and robot Picasso will be a genius.
Is this the future AI art visionaries such as the French collective Obvious, which programmed this “painter” by getting it to compare its own work with 15,000 pre-20th century portraits, have in mind? Or are they just, God forbid, making a fast buck from deceivable art collectors? Because believing the algorithm that knocked this up to be in any meaningful way an “artist” is like thinking your voice-interaction programme is out to get you. Dream on. Computers would need to replicate human consciousness before they could replicate the funny thing humans do called “art”.
Art is a way in which human 【7】 expresses itself, and is equally true of the earliest cave art, Rembrandt’s portraits and Duchamp’s urinal. And that is what is missing from Portrait of Edmond Bellamy. Art is a way humans communicate ideas, perceptions and feelings to each other. It has no 【8】 outside the human passion to communicate. So in what meaningful sense can an AI replica of certain【9】 traits of old master paintings be called art?
For a robot to really make art, it would need an autonomous mind that was emotional as well as【10】. No AI developer has yet claimed to be anywhere near achieving that and if they ever do, their creation will probably have better things to do than paint portraits — like destroy humanity.
Maybe afterwards robots will invent their own kind of art, but it won’t be some poor pastiche of human genius.
It will be beyond anything we organics could imagine.
