21、 We’ve known for years that plants can see, hear, smell and communicate with chemicals. Now, reported New Scientist, they have been recorded making sounds when stressed.
In a yet-to-be-published study, Itzhak Khait and his team at Tel Aviv University, in Israel, found that tomato and tobacco plants can make ultrasonic（超声的）noises. The plants “cry out” due to lack of water, or when their stems are cut. It’s just too high-pitched（音调高的）for humans to hear.
Microphones placed 10 centimeters away from the plants picked up sounds in the ultrasonic range of 20 to 100 kilohertz（千赫兹）. Human hearing usually ranges from 20 hertz to 20 kilohertz. “These findings can alter the way we think about the plant kingdom,” they wrote.
On average, “thirsty” tomato plants made 35 sounds an hour, while tobacco plants made 11. When plant stems were cut, tomato plants made an average of 25 sounds in the following hour, and tobacco plants 15. Unstressed plants produced fewer than one sound per hour, on average.
Perhaps most interestingly, different types of stress led to different sounds. The researchers trained a machine-learning model to separate the plants’ sounds from those of the wind, rain and other noises of the greenhouse. In most cases, it correctly identified whether the stress was caused by dryness or a cut, based on a sound’s intensity and frequency. Water-hungry tobacco appears to make louder sounds than cut tobacco, for example. Although Khait and his colleagues only looked at tomato and tobacco plants, they think other plants also make sounds when stressed.
If farmers could hear these sounds, said the team, they could give water to the plants that need it most. As climate change causes more droughts, they said this would be important information for farmers. “The sounds that drought-stressed plants make could be used in precision agriculture（精准农业）,” said Anne Visscher at the Royal Botanic Gardens, Kew, in the UK.
Khait’s report also suggests that insects and mammals can hear the sounds up to 5 meters away and respond. For example, a moth may decide not to lay eggs on a water-stressed plant. Edward Farmer, at the University of Lausanne, Switzerland, is doubtful. He said that the idea of moths listening to plants is “a little too speculative”.
If plants are screaming for fear of their survival, should we be thankful we can’t hear them?
【1】What did Khait and his team find from their research?
A.Plants made low-pitched sounds when in danger.
B.Plants were able to produce sounds in response to stresses.
C.Plants picked up a wider range of sounds when stressed.
D.Plants made ultrasonic noises to communicate with each other.
【2】How did tomato and tobacco plants react to different stresses according to the text?
A.A plant reacted to different stresses with the same sound.
B.Cut tobacco plants seemed to make weaker sounds than drought-stressed ones.
C.Cut tomato plants produced more sounds per hour than water-hungry ones.
D.Tobacco plants might make louder sounds than tomato plants when short of water.
【3】What’s the main idea of Paragraph 6?
A.Challenges facing farmers in the future.
B.Farmers’ contributions to the research.
C.The potential applications of the research.
D.What the future agriculture will be like.
【4】What is Edward Farmert’s attitude towards the research?
A.negative B.positive
C.neutral D.indifferent
22、BEIJING — China's education authority will tighten the widely criticized policy of “extra credits” for the national college entrance examination to ensure a fairer chance for all exam-takers.
Under the policy, high school students who win awards in national Olympic competitions could get ‘‘extra credits’, up to 20 points for the national college entrance exam. Students with talent in sports and students who are from ethnic groups can also benefit from this policy. The extra credits have increased these students' chances of being admitted by famous universities. Some parents were found to have helped their children fabricate(伪造)award experiences or falsify qualifications to get extra credits.
“It has harmed education equality，” the ministry said.
Xiong Bingqi, vice-chief of the 21st Century Education Research Institute, said the policy is designed to help students who have special talents but may be weak in academic performance to have a chance to receive higher education. It will still be needed but it is time to make the rules fairer," he said.
The ministry said it will reduce the range of competitions whose winners can get extra credits, and limit the winners, privileges.
The new policy will apply to students who begin high school in 2011, it said.
Chen Lei, a mother of a 10-year-old girl, said she welcomed the ministry's policy adjustment as she does not want her daughter to become an Olympic competition geek.
But not all the Chinese parents welcomed the new policy. “It is like a thunderbolt for me. My 13-year-old son has spent so much time studying Olympic math, and participated in so many technological competitions during vacations. It is useless now,” said Dong Wen, a 43-year-old mother.
A student said, “Many students have changed the current study plan, and they can abandon the competition. I will be interested in learning the courses which can improve my abilities.”
Yuan Guiren, minister of education, told China Daily that the reform is an attempt to consider the overall quality of an applicant. “But the country will not stop the national college entrance examination as it is still the most objective way to evaluate talent in China,” he said.
【1】It can be inferred from the passage that_____.
A. high school students with talent in sports are weak in academic performance
B. students who win awards in Olympic competitions can't get extra credits in 2011
C. the number of competitions whose winners can be awarded extra credits will be smaller
D. he extra credits have reduced students' chances of being admitted by famous colleges
【2】What does the underlined word “geek” probably mean?
A. a winner B. a smart learner
C. a competitor D. a dull student
【3】Which person in the passage was strongly against the new policy?
A. Xiong Bingqi B. Chen Lei
C. Dong Wen D. Yuan Guiren
【4】What might be the best title for the text?
A. “Extra credits” policy in China to be adjusted
B. Promotion of national Olympic competitions
C. Advice on the national college entrance exam
D. Chinese government to push education reform
23、 In quiet neighborhoods, you find quiet people going about their lives, doing good things. Harold is one of those people. A quiet man by nature, he finds himself happiest while changing the brake pads on an old truck or replacing a water heater.
As a mechanic, Harold runs a workshop after retiring. His wife Jeannette teaches English at the local high school. With their own kids grown, they don’t need a lot or want a lot, so Harold and Jeannette live a simple life. And while his wife is in the classroom. Harold often walks around in the neighborhood. There’s always a widow who needs a lamp fixed or a teenager who needs a tire changed.
Each day, Harold pulls on his coveralls (工作服) and goes to work. His wife teaches students to speak, while Harold economizes language. “Yep, you got a leak. I’ll get my toolbox.” That’s about as much as you’ll get out of Harold. Even when you thank him, he’ll just wave.
In a world of social media, massive information floods our screens, with various ways to communicate. But if you want to talk to Harold, you have to go to his workshop and knock on the door. It’s reassuring to know that there’s Harold, willing to fix the mechanical things that stress us out. He always works slowly and methodically, removing the old pipe, pulling it to his truck, and cutting a new pipe. He’s done this hundreds of times. There’s no frustration, no hurry, only an ease and satisfaction, like a gardener taking care of his beloved flowers.
Shortly after Jeannette retired, Harold passed away from a rare disease. Harold saved his words, but his friends and family didn’t. A flood of appreciation came pouring out. “He was there when I needed a hand,” many said. What a valuable thing in these days! After all, the purpose in life is not to get the most likes, but to like most what you do.

24、 Nowadays six Amazon Scout delivery robots rolled out in a pilot program in Snohomish County, Wash. The robots carry meals, groceries and packages to homes and offices in this region just north of Seattle. They have appeared on the sidewalks of London, Beijing and other cities and communities worldwide. These machines must overcome pedestrian legs, naughty dogs and broken pavement, which raises some questions.
These services are gaining attraction as a growing number of city residents expect immediate or scheduled delivery for just about everything. Between 2017 and 2018 online retail sales in the U.S. increased by 16 percent. On the final step of all these deliveries, called the last mile, humans on bicycles, motorized scooters ( 电动车) or large delivery trucks typically deliver packages. All the vehicles compete for space on busy urban streets. “Deliveries are trending upwards in all crowded city centers, and if city and state leaders don’t start thinking about creative solutions like robot deliveries, we can expect even worse traffic jams,” says Paul Mackie, director of a transportation policy research center in Arlington.
A study by this center found 73 percent of delivery vehicles in Arlington were parked outside of authorized areas, often blocking bike lanes and crosswalks. By moving the last step of deliveries from the road to the sidewalk, cities could reduce traffic jams and solve the parking problem entirely, Mackie says.
Companies such as Amazon are not developing this delivery technology simply to clear up urban traffic. Self-driving vehicles and sidewalk robots could cut down last-mile delivery costs in cities by as much as 40 percent, according to a 2018 report by a consultancy firm. A delivery robot can cost thousands of dollars to manufacture, and most currently require human management and conservation. But in the long run companies that use autonomous delivery vehicles in the next several years could end up saving billions of dollars, the report stated.
【1】Why does Amazon introduce delivery robots ?
A. To amuse its customers.
B. To avoid pedestrians, dogs and broken pavement.
C. To meet the increasing demand of delivering packages.
D. To confirm the company’s innovation spirit.
【2】What does Paul Mackie mean by his words in paragraph 2?
A. Retail sales in the U.S. increased fast.
B. Deliveries stay steady in all crowded city centers.
C. Regardless of robot deliveries, traffic jams will remain the same.
D. Robot can help ease the traffic pressure.
【3】What can robots delivery bring to the city?
A. Block bike lanes and crosswalks.
B. Relieve urban traffic as well as save delivery costs.
C. Increase danger to pedestrians.
D. Lead to traffic traffic jams.
【4】Which word can best describe the future of the robot delivery?
A. Uncertain. B. Hopeless. C. Promising. D. Unacceptable.

26、Directions: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.
Great Speakers: Why Their Words Resonate (产生共鸣)
This year will mark 55 years since Martin Luther King, Jr. delivered his “I Have a Dream” speech, one that put him among the greatest speakers in history.
What gave “I Have a Dream” and other historic speeches ---such as Abraham Lincoln's“Gettysburg Address”and Winston Churchill's “We Shall Fight on the Beaches” ---such power that they are still distinctly remembered today?
Certainly, it demands perfect delivery. If J.F.Kennedy had gotten up there and mumbled (含糊地说) through his address, we probably wouldn't remember that he said, “Ask not what your country can do for you; ask what you can do for your country.” But there are more to a great speech.
A great speech seizes the historical moment. Franklin D. Roosevelt's classic line --- “The only thing we have to fear is fear itself” --- was delivered during his speech in 1933 at the worst point of the Great Depression. It inspired Americans to regain a sense of confidence and hope, Gerard Hauser, professor of communication at the University of Colorado, says, “A great speech resonates with problems that people are feeling and the expectations they have with respect to those problems.”
A great speech has a memorable tag line. The trick is to deliver a phrase the audience can start repeating, which allows the speaker to pause, and the audience to repeat louder. U.S. President Barack Obama is excellent at this. “When the audience is cheering, he pauses, and then continues to speak, and they cheer louder, so it builds to a kind of peak’’ Hauser says.
A great speech reminds listeners of great moments of the past, linking the speaker with history. Ronald Reagan was considered a master at this. His speech in 1980, as he accepted the presidential nomination, brought the audience back to America's first days. “Three hundred and sixty years ago, in 1620, a group of families dared to cross a mighty ocean to build a future for themselves in a new world,” he said, linking past to future with his appeal for “a new compact (契约) with America.’’
