It was almost New Year’s Eve, and as I made my way home from work, I decided to stop at the neighborhood coffee shop in our town—a town that had previously been busy and wealthy but was now poor and deserted. After parking in a parking lot that was close to the coffee shop, I headed toward the shop door when I spotted trouble.
What lit a warning light in my mind was a group of teenagers—three boys and a girl, each of whom stood on a skateboard. I wasn’t alarmed by the way they were dressed, which showed they seemed to be a group of bad teenagers. Rather, it was the extremely late hour and the fact that they wandered on the sidewalk in a half circle around an elderly man sitting in a chair that raised a red flag in my mind. Wearing only a very worn-out shirt and without shoes on his feet, the old man looked positively cold and probably homeless.
He was in trouble with a capital T. Against my better judgment, I went inside the warm store and ordered nice bread and a cup of coffee while keeping a worried eye on the group outside. Thoughts raced through my mind, and I was wondering what the intentions of these teenagers were. “What do the teenagers want on earth? Do they intend to play a bad trick on the old man, make fun of him, or…?” I wondered, anxious. “Whatever it is, they seem to plan to do something bad to him. Oh, these kids seem to be mean,” I thought and felt upset.
But nothing seemed to be happening. Slightly relieved, I began to enjoy my food. However, minutes after I finished my food and headed toward my car, something indeed was “going down”. I heard one boy say, “Stand up and walk.” “Oh, no,” I thought. “The old man is now in real trouble.”

4 . Hummingbirds occupy a unique place in nature: They fly like insects but have the bone and muscles of birds. According to Bo Cheng, a professor in Mechanical Engineering at Penn State, hummingbirds have incredible agility (敏捷) when flying through the air, which is why their flight behavior is often mimicked in the design of drones and other flying vehicles.
Using a new modeling method, Cheng and his team gained new insights into how hummingbirds produce wing movement, which could lead to design improvements in flying robots. “We essentially analyzed how the muscles and skeleton (骨骼) work in hummingbirds to flap the wings,” said Cheng. “The traditional methods have mostly focused on measuring the activity of a bird or insect during natural flight or in an artificial environment where flight-like conditions are reproduced. But most insects and, among birds specifically, hummingbirds are very small. The data that we can get from those measurements are limited.”
The researchers employed various methods to inform and adjust their model. With this model, they uncovered previously unknown methods of hummingbird wing movement. The discovery was that hummingbirds tighten their shoulder joints in both the up-and-down direction and the twisting direction using various smaller muscles.
“It’s like when we do fitness training and a trainer asks us to tighten our core to be more agile,” Cheng said. “We found that hummingbirds are using a similar kind of procedure.” They tighten their wings in the twisting and up-and-down directions but keep the wings loose along the back- and-forth direction. So their wings appear to be flapping back and forth only while their power muscles, or their flight engines, are actually pulling the wings in all three directions. In this way, the wings have very good agility in their motion.
While Cheng stressed that the results from the new model are predictions that will need confirmation, he said that it has suggestions for technological development of flying vehicles. “Even though the technology is not there yet to fully mimic hummingbird flight, our work provides essential methods for informed mimicry of hummingbirds hopefully for the next generation of agile flight systems.”

7 . Imagine getting ready for bed, brushing your teeth, setting your alarm and then putting a device on your head that allows you to control your dreams. It might sound like something unfeasible, but it’s the real-life promise of a new futuristic-looking headband called Halo, at present in development by US tech company Prophetic.
Expected to be released in 2025, Halo aims to allow you to have more lucid dreams (清醒梦). In some cases, you might also exercise a degree of control over what happens in these dreams, perhaps in ways that benefit your waking life, such as solving work problems, practicing guitar and more.
Earlier research has shown lucid dreams could be used for real-life benefits. For example, one study carried out by researchers at the University of Bern, Switzerland showed that participants who practised casting coins into a cup in their lucid dreams showed superior performance the next day.
The team behind Halo are using technologies like EEG (脑电图) to collect vast amounts of brain data from volunteers experiencing lucid dreams. The idea is to build a detailed map of what’s happening in the brain during different types of lucid dreams. This information will be key for the second main area of investigation, which involves using TUS (delivered via the headband) to control brain activity. TUS, a non-invasive brain stimulation technique, can change brain function by using high-frequency sound.
“It’s seemingly true that the sound stimulation could contribute to the high-frequency brain activity that’s associated with lucidity,” says Professor Mark Blagrove, a sleep scientist based at Swansea University. “Sound stimulation has been used to cause low-frequency slow waves in slow wave sleep, so the method suggested is believable.”
However, TUS is a relatively new approach to brain stimulation and it’s not entirely clear what the long-term results of stimulating your brain with high-frequency sounds might be. Moreover, some sleep scientists believe dreams have basic functions, including processing emotional experiences. By using a device to change the nature of your dreams, maybe you risk interrupting the usual purpose of your dreams.
1. What does the underlined word “unfeasible” in paragraph 1 probably mean?A.Impossible. | B.Significant. | C.Logical. | D.Meaningless. |
A.To suggest a way to dream a dream. | B.To provide a theory for developing Halo. |
C.To prove the benefits of lucid dreams. | D.To indicate the meaning of being awake. |
A.The way in which EEG works. | B.The reason for designing Halo. |
