21、 Your colleague’s sharp comment keeps replaying in your mind.Two of your students are trapped in a”he said/she said”battle.When you reflect on your emotional reactions,you sometimes get caught up in cycles of negative feelings,which can make you feel even worse.If so,the answer may lie in a skill called”self-distancing”,the ability to take a step back and view yourself more objectively.According to a research,when people adopt self-distancing while discussing a difficult event,they make better sense of their reactions,experience less emotional suffering,and display fewer signs of stress.
But what might self-distancing look like in action? Consider a typical”he said/she said”student conflict where they are each focusing on their own feelings.One is thinking,‘‘I can't believe he did that to me”And another insists.”She really hurt my feelings”However,if you ask them to take the self-distancing,they might step outside of themselves and ask broader questions:”Why was he so hurt in this situation?”or”How did her anger affect him?”
Although this approach may sound too simple to be effective,studies indicate that a change in point of view can have a powerful effect on the way people think,feel,and behave. Here are several different techniques you can try.
First,consider how a thoughtful friend might respond after quietly observing their situation.Besides,avoid using the pronoun”I”.Focus on using third-person pronouns,he,she,they,and they were able to see the stressful event as challenging rather than threatening.Finally,ask yourself,”How would I feel about this one week from now or ten years from now?”This form of mental time travel may be effective because our attention is directed away from our immediate,concrete circumstances.
【1】What is self-distancing?
A.Getting stuck in negative emotions.
B.A stressful situation.
C.A study on relieving emotional stress.
D.Reflecting on yourself objectively.
【2】Which of the following statement uses the techniques of self-distancing?
A.I’m angry with him.
B.How did these two people get to this point?
C.How I wish I could go back to the past!
D.He grabbed my notes,and then,and then…
【3】What is the best title for the passage?
A.Why Self-distancing Matters
B.The Disadvantages of Self-distancing
C.Breaking the Cycle of Negative Reflection
D.Ways to Reflect on Emotional Reactions
22、The sound of a mosquito can mean trouble in many parts of the world. The bite of the mosquito can be deadly. The insects carry serious diseases like malaria (疟疾). It is estimated that almost 630,000 people died from malaria and malariarelated causes in 2012, and most of these cases were in African countries.
In the United States, a group of California scientists are working to develop a more effective and less costly substance (物质) to protect people from mosquitoes. The researchers are investigating the sense of smell in mosquitoes. They found the insects use the same receptor for identifying carbon dioxide in human breath as they do for the smell of our skin. Anandasankar Ray, who is leading the investigation, says scientists tested more than a million chemical compounds (化合物) until they found a substance called Ethyl Pyruvate. He says Ethyl Pyruvate makes the mosquitoes' receptors inactive. “When we apply Ethyl Pyruvate to a human arm and offer it to hungry mosquitoes in a cage, very few of the mosquitoes are attracted to the human arm because only a few of them are able to smell it out,” said Ray.
Genevieve Tauxe, a member of the research team, says it was not easy to find the neurons (神经元) of noble cells that recognize both the smell of human breath and skin. “With the device used to examine the mosquito, we are able to insert a very small electrode (电极) into the part of the mosquito's nose, where its smelling neurons are and where the smell is happening,” said Tauxe.
Anandasankar Ray says a product based on Ethyl Pyruvate may cost less to produce than DEFT, the most effective chemical treatment now in use. He says DEFT is too costly for most people who live in areas affected by malaria.
“Perhaps by finding smells that can attack other target receptors, we will be able to improve upon DEFT and finally have the next generation of insect behaviour control products,” said Ray.
【1】The underlined word in the second paragraph probably means ________.
A. a substance that protects people from mosquitoes
B. a piece of equipment that sends signals
C. a device that reacts to light
D. a sense organ that reacts to changes
【2】According to the passage, Ethyl Pyruvate can ________.
A. kill the mosquitoes' smelling neurons
B. cause the mosquitoes to lose their senses of smell
C. result in the inactiveness of the mosquitoes' receptors
D. make the mosquitoes uninterested in human breath and skin smell
【3】Which of the following would be the best title for the passage?
A. Ethyl Pyruvate—an Insect Behaviour Control Product
B. Malaria—a Serious Disease Causing 630,000 Deaths
C. Scientists Find a New Substance to Fight Mosquitoes
D. A New Generation of DEET Has Been Developed to Kill Mosquitoes
【4】This passage most probably appears in ________.
A. a textbook of medical schools

23、 The two-hour show on March 25, 2019 put on by Tim Cook may be remembered as a milestone for the company – and the entertainment industry. Mr. Cook did not announce his company’s latest device. Instead, he unveiled a set of products and services, including video streaming, news games and even a credit card.
Apple’s 900 million iPhones worldwide grant it access to a massive potential audience. Analysts speculate that Apple will eventually offer them something similar to Amazon Prime, where customers pay a fixed monthly fee for some combination of news, games, cloud storage, music and video, and which could possibly connect with the company’s iPhone subscriptions.
Apple TV+, which got prioritized by Mr. Cook, will offer original programming in more than 100 countries. The money Apple plans to spend on original shows – perhaps $1 billion to $2 billion thus far – is dwarfed by that of Netflix, which will spend as much as $15 billion this year on original and licensed content, or Disney, whose own video-streaming is expected shortly. But Apple’s high-profile shows are for now meant chiefly to draw customers to its universe of apps and services. That includes subscription services for games, a long list of big American magazines and a few newspapers. You can pay for it all using your new Apple Card, developed with bankers at Goldman Sachs. The credit card puts Apple in direct competition with banks: it has no fees and will give users 2% cash back on purchases made via Apple Pay, the company’s payments system – or 3% on purchases of Apple kit and service.
Although Apple continues to earn most of its money from devices, its business in services is growing quickly, accounting for nearly $40 billion of revenues of $266 billion in 2018. The new subscription offering, which is easier to click and buy than their predecessors, should accelerate that trend. Its new partners hope to be along for the ride. Analysts at Goldman Sachs estimated that Apple may turn 10% of the 85 million monthly users of its free News app into paying subscribers, wining a cut of newspaper and TV subscriptions sold through its services.
Some content providers are cautious. The New York Times and The Washington Post have rejected Apple’s advances on behalf of its news service. Netflix and Disney will not take part in Apple TV+, which they view as more a threat than an opportunity.
【1】The underlined word dwarfed in paragraph 3 most probably means ________.
A.made to appear insignificant B.reduced to a great extent
C.limited to a fixed scale D.grown to its full potential
【2】We can infer from the article that ________.
A.Apple invested heavily in its entertainment services along with its latest devices
B.Apple Card may be favoured because it offers discounts on purchases of Apple products
C.The popularity of Apple devices may bring forth huge profit potentials in its new service
D.Apple’s new move is seen as an opportunity as well as a threat by its competitors
【3】What is most likely to be further discussed if the article continues?
A.What action Apple might take to attract potential subscribers.
B.Who might gain huge benefits from Apple’s new service.
C.How Goldman Sachs won the support from Mr. Tim Cook.
D.Why some companies are alert to Apple’s strategy changes.
【4】What is the best title for this article?
A.Tech Giant Apple Stages New Moves B.A Great Challenge to the Entertainment Industry
C.The Entertainment Industry Calls for Cooperation D.A New Bottleneck for Tech Giant Apple
24、Rene Compean had hiked the park near his home in Southern California many times. But after exploring a new path last April, he was lost.
With no flashlight, only a little water and less than ten percent battery remaining on his cell phone, Compean climbed to a spot where he found at least one bar of signal. “SOS. My phone is going to die. I’m lost,” he texted a friend, attaching a photo showing where he was. The shot showed his dirty legs hanging over a number of steep rocks. All Compean could do then was to wait and hope.
Sixty miles away in Ventura, Ben Kuo was working at home when he read a tweet from the Los Angeles County Sheriff’s Department, showing an unclear image of a man’s legs. The sheriff’s search-and-rescue teams had spent the previous night unsuccessfully looking for Compean, so they released the photo to the public, hoping someone might know the location.
When he saw the unclear picture, he pulled up a satellite map on his laptop. The first thing he noticed in Compean’s photo was patches of greenery. After comparing it to the satellite map, Kuo realized something: He’s got to be on the south side because there’s not really any green valleys on the north side.
That finding tightened his search, leading him to an area that resembled the place in the image. The final step was cross-referencing(相互参照) the original photo with 3D images of the area from Google Earth. The locations matched!
He quickly called the sheriff’s department with the latitude and longitude supplied by Google Earth. Soon, a search-and-rescue team helicopter was in the air, hovering above Compean.
After spending 27 hours alone in the wilderness, Compean cried, “I’m safe!”
Sgt. John Gilbert in the sheriff’s department thought Compean’s story probably would have ended very differently had a total stranger with strong satellite skills and a sharp eye for detail not taken action.
【1】Why did Rene Compean get lost?
A.Something was wrong with his legs.
B.He didn’t have a flashlight and water.
C.He was not familiar enough with the path.
D.His phone failed to work well in signaling.
【2】Which of the following best described Rene Compean after he got lost?
A.Calm.
B.Thrilled.
C.Tired.
D.Adventurous.
【3】What mainly contributed to Compean’s successful rescue?
A.Google Earth’s supply of location.
B.The Sheriff’s Department’s rescue effort.
C.Compean’s previous kindness towards others.
D.The stranger’s kindness and his satellite skills.
【4】What can be inferred from the text?
A.Compean likes exploring unfamiliar paths.
B.The stranger found the right location without effort.
C.Technology has become increasingly significant in our lives.
D.Hiking without full preparation can surely lead to trouble.

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.
Rock Climbing — conservationists’ new concern
Now, with its first appearance at this year’s Tokyo Olympics, the once minority sport is set to reach new heights. Yet the popularity of rock climbing and its sister sport, bouldering (where climbers scramble up large rocks without the use of ropes or safety belts), is raising questions about the damaging environmental effects of climbing chalk — a common and essential climbing tool.
Made from magnesium carbonate (碳酸镁), climbing chalk is the same substance that gymnasts and weightlifters use to improve their grasp on bars and weights. In fact, it was first introduced to rock climbing in the 1950s by John Gill. Since then, amateur and professional climbers alike have come to depend on the chalk’s properties of removing water and increasing friction (摩擦力) — and have been leaving long stripes of the stuff on rock faces around the world.
The resulting “chalk graffiti” has become so bad in the United States that parks are beginning to restrict its use. Utah’s Arches National Park allows only colored chalk that mostly matches rocks, while Colorado’s Garden of the Gods National Natural Landmark banned all chalk and chalk substitutes.
Beyond the visual pollution, new research suggests chalk may be harming the plants that grow on rocks. The latest study on the effects of climbing chalk, released October 2020, found that it negatively impacted both the growing and survival of four species of ferns and mosses (蕨类和苔藓) inhabiting rocks in laboratory settings.
That matters because some climbing spots, such as erratic boulders (the study’s focus), host unique ecosystems. These unpredictable boulders — rocks scattered across the globe by large masses of slowly flowing ice at the end of the Ice Age — are islands of vegetation, different from the land they sit on.
It’s not even clear whether chalk improves climbing performance at all. Some papers found no additional grip benefits, while others found the opposite. Some climbers may find it helpful, says Daniel Hepenstrick, a co-author of the 2020 study and a doctoral candidate at ETH Zürich.
