26、 Felicien, a 29-year-old African graduate student, smiled as he helped a woman use a ticket on her phone to enter the Summer Palace in Beijing. As a volunteer in the palace garden, Felicien is just one of many African students studying in China.
The China-Africa Cooperation Meeting was held in Beijing from Sept 3 to 4. On the meeting, Chinese President Xi Jinping promised to offer working training courses, 50,000 scholarships for African youths and invite 2,000 young African people to visit China. "The future of China-Africa relations lies in our young people," Xi said. He also said that China will provide $60 billion in support, including free aid and special funds, for Africa's development.
The friendship between China and Africa dates back 600 years to the travels of Chinese explorer Zheng He, whose ships reached East Africa four times. Zheng brought gifts to his African hosts and took back nothing but a few giraffes. Today, China sees Africa as an equal partner in development and in international and regional affairs. China has been Africa's largest trading partner for 9 years. Chinese investments in Africa have increased more than 100 times in the past 18 years. China and Africa have strengthened cooperation since 2013, with the tremendous help of the Belt and Road Initiative (BRI).
"China follows the principle of giving more and taking less, giving before taking and giving without asking for return. With open arms, we welcome African countries aboard the train of China's development, Xi said. Xi's words received much praise from African leaders.
Indeed, "With goodwill and cooperation with Bejing, Africa can bring her wisdom on board, mix it to the Chinese Dream and jointly build a community of shared future for all mankind,", commented an expert

27、 I watch from the wooden bench in my backyard as the water from the pipe quietly flows out onto the tomato plants. I watch the plants and rest easy, knowing the pipe is taking care of the plants. The drops soon seem to become rivers on the ground.
I see these red-brown ants, crawling(爬行) along around their home. What will happen when the water reaches the ants? Smelling the danger, these poor tiny creatures all run away from the water and rush back to their home. They spend their whole lives working together to create and make better things, but now they are facing the end of it all. I think this is just a reflection of the world. I keep watching as the water first attacks and then surrounds two ants. They struggle to stay floating as the water closes in on them, getting deeper and deeper. I try to get these two to come on my finger, but they refuse to let me save them. The water soon flows over them, as I remain helpless. Only then do they decide to climb onto my dirt-covered finger. Not until facing the moment of death would they trust one like me.
I check to see if they are alive, and both can move fine. Then I go to save other ants. However, the water washes everything away. How much I wish I could turn off this machine of death, but I cannot. I must complete my job.
It knocks me how much these little lives mean to me. When I was a small child, I would make a sport of killing them. Now, I can't hurt an insect, always thinking about what it would be like to be so small.
【1】What is the ants' first reaction as the water approaches them?
A. They attempt to stop it.
B. They seek help at once.
C. They ignore it and continue to work.
D. They try to avoid the danger caused by it.

A. Behind bad luck comes good luck.
B. Where there is a will, there is a way.
C. God helps those who help themselves.

C. Favorable. D. Cruel.
28、 It was an autumn day, and 1 was standing in the kitchen, hanging my head over the counter and trying to figure out how many calories were in a bowl of homemade yogurt and fruit. And I felt annoyed.
I was 16, and my best friend and I had gone to our first Weight Watchers meeting. It was the trend in the mid-1980s,and even though I was an athlete, like many teen girls, I didn't necessarily like what I saw in the mirror. But after a week or so of recording every meal and snack and calculating the calories, I had had enough. I went back to my routine of chowing whatever I wanted, running and skiing, and let that be that. And it's still pretty much what I do; as long as the workouts are regular and the food is whole and balanced, my body's set point hasn't varied for years.
The weight loss trend of three decades ago−full of scales and counting calories−has fallen away. Now fasting is popular. The ways to keep fit vary: on the 5:2 diet a person eats for five days and fasts for two days each week, while the 18:6 refers 10 fasting for 18 hours and then eating within a six-hour window each day.
In this issue, Associate Editor Mark Barna tries to understand the science behind the fasting plans. Researchers have found that animals like monkeys age more slowly after years of eating less, and in the lab in humans, they saw improvements in a number of signs that indicate risk of some hard to cure diseases. The hope for healthy weight loss isn’t over yet, but at least now the calculators don’t have to be out at every meal.
【1】What made the author annoyed?
A. Her body was not as strong as an athlete’s.
B. There were too many calories in the yogurt and fruit.
C. The Weight Watches meeting was not necessary for her.
D. She had to work out the calories in every meal and snack.
【2】Which of the following can replace the underlined word “chowing”?
A. Eating. B. Doing C. Cooking. D. Choosing.
【3】How do people keep fit now?
A. They limit the calories they take in.
B. They lose weight only.
C. They fast daily or weekly.
D. They eat enough every day.
【4】What do we know about the researchers’ finding in this passage?
A. People grow more slowly if they eat less.
B. People are healthier if they eat less.
C. People have stopped losing weight now.
D. People calculate their food for every meal.
29、 When there’s a heat wave, ocean temperatures rise. That heat causes coral reefs (珊瑚礁) to lose their color, which shows the corals are dying. Fish then leave, and without the fish activity, reefs fall silent. A new study finds playing the sounds of a healthy reef can attract fish back to dead or dying areas. Indeed, those sounds could help bring a reef back to life.
Tim Gordon, a biologist at the University of Exeter in England, studies the effect of sound on sea animals. He and his research group “felt surprised at so many different sounds you can hear on a healthy reef”. They were shocked by how quiet the reefs became as they died. That got them wondering: Could sound help renew dying reefs by attracting fish?
So Gordon used pieces of dead coral to create small patches (小块) of reefs along the Great Barrier Reef. He placed them at least 25 meters from each other and from other reefs. Gordon left eleven patches alone. These served as his controls. He set up a loudspeaker around another eleven patches. The speakers played healthy reef sounds. The last eleven patches served as a different type of control. They got a set-up that looked like the loudspeaker but played no sound.
Fish arrived at all three types of patches. But they showed up more quickly at the ones that had sound. Besides, those small reefs ended up with twice as many fish by the end of the experiment. Reefs with sound also had more species overall. Gordon found no difference between the two types of controls. It was sound, not the speaker set-up , that had attracted the extra fish. Playing healthy reef sounds adds another powerful tool to restore our reefs, Gordon says.
【1】What has led to the death of coral reefs?
A.Too many fish. B.Noise pollution.
C.Loss of their color. D.High ocean temperatures.
【2】What is the purpose of the second paragraph?
A.To introduce sounds of a healthy reef. B.To raise doubts about dying coral reefs.
C.To explain the reason for the new study. D.To show the positive effect of fish on corals.
【3】What did Gordon and his team do in their study?
A.They played healthy reef sounds for two groups of patches.
B.They created 33 patches with the collected pieces of dead coral.
C.They set up a loudspeaker around all the patches of dead coral.
D.They played sounds to attract fish to approach all the patches.
【4】What is the main idea of the text?
A.Healthy coral reef sounds attract fish back to dead reefs.
B.Dead coral reefs are especially dependent on healthy sounds.
C.The speaker set-ups of coral reefs are attractive to most fish.
D.Underwater speakers may remind coral reefs of possible threats.

34、Directions: Fill in each blank with a proper word chosen from the box. Each word can be used only once. Note that there is one word more than you need.
The Internet E-commerce and globalization are making a new economic age possible. In the future, capitalist markets will largely be replaced by a new kind of economic system based on 【1】 relationships, contractual arrangements and access rights.
Has the quality of our lives at work, at home and in our communities increased in direct proportion to all the new Internet and business-to-business Internet services being introduced into our lives? I have asked this question of hundreds of CEOs and corporate executives in Europe and the United States. Surprisingly, virtually everyone has said, “No, quiet 【2】.” They say they are working longer hours, feel more stressed, are more impatient, and are even less civil in their dealings with colleagues and friends-not to mention strangers. And what’s more revealing, they place much of the blame on the very same technologies they are so 【3】 supporting.
The technological leader promised us that access would make life more convenient. Instead, the very technological wonders that were supposed to 【4】 us have begun to enslave us in a web of connections from which there seems to be no easy 【5】.
If an earlier generation was preoccupied with the quest to enclose a vast 【6】 land, the .com generation, it seems, is more caught up in the colonization of time. Every spare moment of our time is being filled with some form of commercial connection, making time itself the 【7】 of all resources.
And while we have created every kind of labor-and time-saving device to service our needs, we are beginning to feel like we have less time available to us than any other humans in history. Maybe we need to ask what kinds of connections really 【8】 in the e-economy age. If this new technology 【9】 is only about super efficiency, then we risk losing something even precious than time-our sense of what it means to be a(n) 【10】 human being.

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.

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.
37、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.

40、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.
