1 . “A moth (飞蛾) to a flame” is often used to indicate an inescapable attraction, yet it is a strange example of animal behavior that continues to confuse people today. Scientists have raised a number of theories over the years to explain why. One holds that insects flying at night are following their nature to fly toward the brightest spot in their field of vision, which they mistake for the sky. Another suggests that insects are trying to warm themselves with the heat produced by the light. The most popular theory, though, is that insects are confusing lights with the moon or other celestial bodies (天体) that they normally use to navigate (导航).
To find out the real reason, the team carried out a first set of experiments in an insect flight area. The researchers used eight high-speed infrared (红外线) cameras equipped with motion-capture technologies to track 30 insects from three moth and two dragonfly species. They also flew lab-raised insects from six different insect orders that were too small for motion-capture technology, including fruit flies and honeybees, to make sure different insects all showed similar responses to light. Working with co-author Pablo Allen of the Council on International Educational Exchange in Monteverde, Costa Rica, the researchers put heavy cameras, lights and tripods in two field sites to gather behavioral data from insects in the wild.
The team was able to confirm that insects were not beelining to the light but rather circling it as they tilted (倾斜) in an attempt to turn their backs toward it. This behavior, known as a “dorsal light response”, normally helps insects to remain in an unchanging path of flight that is properly lined to the horizon (地平线). Artificial light that arrives from a point source causes them to fly in unpredictable patterns as they try to turn their backs to what they are mistaking for the sky.
Now research might have finally solved the mystery mentioned first: artificial light confuses insects’ ability to turn themselves to the horizon, confusing their sense of what is up and down and causing them to fly in circles.

3 . You are what you eat-and what you eat may be encoded in your DNA. Studies have indicated that your genes play a role in determining the foods you find delicious or disgusting. But exactly how big a role they play has been difficult to figure out. “Everything has a genetic component even if it’s small,” says Joanne Cole, a geneticist at the University of Colorado School of Medicine. “We know that there is some genetic contribution to why we eat the foods we eat. Can we take the next step and actually locate the regions in the genome (基因)?”
New research led by Cole has gotten a step closer. Through a large-scale genomics analysis, her team has identified 481 genome regions that were directly linked to dietary patterns and food preferences. The findings, which have not yet been peer-reviewed, were presented last month at the American Society for Nutrition’s annual conference.
The team based the new study on a 2020 Nature Communications study by Cole and her colleagues that used data from the U.K. Biobank, a public database of the genetic and health information of 500,000 participants. By scanning genomes, the new analysis was able to identify 194 regions associated with dietary patterns and 287 linked to specific foods such as fruit, cheese, fish, tea and alcohol. Further understanding how genetics impact how we eat could reveal differences in nutritional needs or disease risks.
“One of the problems with a lot of these genomics studies is that they’re very small. They don’t have enough people to really be able to identify genes in ways that are credible. This study had a huge group of people, so it’s really powerful.” says Monica Dus, a geneticist at the University of Michigan. “The other thing that I thought was really great is that there are so many different features that they’re measuring related to diet including cholesterol (胆固醇), the body and socioeconomic backgrounds.” As the research advances, Dus says, such genome analysis could potentially assist health care providers and even policymakers to address larger issues that affect food access and health.
It’s definitely true that it may contribute to making sure there aren’t food deserts-areas which have limited access to fresh, healthy and affordable food or to making sure that there’s a higher minimum wage so that everyone can afford to eat, although the journey ahead remains lengthy and challenging.

Brit works full time as a fourth-grade teacher at Kula Elementary School. It was there that she met Seth Snyder, a student who had flown under the radar with previous teachers. Every year, Brit is given a nine-month window in which to connect with a group of new students. And with each batch of new students, she hopes to have a positive impact on their lives. But Seth was a tough cookie to crack. For the first few months of the school year, she struggled to connect with her student, who was shy but nevertheless a pleasure to have in the classroom.
One day, Brit showed her students a clip of skateboarders going all out at Tony Hawk’s ramp in California. Brit glanced over and watched Seth’s face light up; she found their connection. She went one step further to connect with Seth by inviting him to join her at the skate park after school one day. Instead of excitement, Seth shut down. He politely declined his teacher’s offer and withdrew once more. In spite of that, Brit wouldn’t give up so easily. She asked again a few weeks later, the day Seth and his fellow students were cut loose for spring break.
“What are you going to do?” she asked. “Are you going to skate?”
“No,” he mumbled, almost embarrassed. “I don’t have a skateboard.”
Brit’s heart sank into her stomach. Kula Elementary comprises mostly underprivileged (缺少机遇的) students who come from low-income families. Teachers like Brit have to tread (行事) carefully when it comes to even the smallest conversations or assignments, because a question as innocent as “What are your plans for spring break?” can be hurtful, sometimes embarrassing, for students who have so little.
Brit said to the reporter, “If your parents are working three jobs to be able to pay rent, of course they’re not going to have time to take you to skate park or, you know, take you surfing, or let alone buy you that $400 surfboard or $ 200 skateboard.”
注意：1．续写词数应为150左右；
2．请按如下格式在答题卡的相应位置作答。
Brit shared the story with her best friend, Zach, a professional skateboarder.

5 . Any schoolchild knows that a whale breathes through its blowhole. Fewer know that a blowhole is a nostril (鼻孔) slightly changed by evolution into a form more useful for a mammal that spends its life at sea. And only a dedicated expert would know that while toothed whales, such as sperm whales, have one hole, baleen (鲸须) whales, such as humpback and Rice whales, have two.
Even among the baleen whales, the placing of those nostrils differs. In some species they are close together. In others, they are much further apart. In a paper published in Biology Letters Conor Ryan, a marine biologist at the Scottish Association for Marine Science, suggests why that might be. Having two nostrils, he argues, helps whales smell in stereo (立体空间).
Many types of baleen whales eat tiny animals known as zooplankton (浮游动物), which they catch by filtering (过滤) them from seawater using the sheets of fibrous baleen that have replaced teeth in their mouths. But to eat something you first have to find it. Toothed whales do not hunt by scent. In fact, the olfactory bulb—the part of the brain that processes smell—is absent in such creatures. But baleen whales still have olfactory bulbs, which suggests smell remains important. And scent can indeed give zooplankton away. Zooplankton like to eat other tiny creatures called phytoplankton (浮游植物). When these are under attack, they release a special gas called dimethyl sulphide, which in turn attracts baleen whales.
Most animals have stereoscopic senses. Having two eyes, for instance, allows an animal to compare the images from each in order to perceive depth. Having two ears lets them locate the direction from which a sound is coming. Dr Ryan theorized that paired blowholes might bring baleen whales the same sorts of benefits.
The farther apart the sensory organs are, the more information can be extracted by the animal that bears them. The researchers used drones to photograph the nostrils of 143 whales belonging to 14 different species. Sure enough, baleen whales that often eat zooplankton, such as the North Atlantic right whale, have nostrils that are farther apart than do those, such as humpback whales, that eat zooplankton occasionally. Besides allowing them to breathe, it seems that some whales use their blowholes to determine in which direction dinner lies.

7 . The most hated day of the week is misunderstood. When the Boomtown Rats, an Irish band, released “I Don’t Like Mondays” in 1979, the song became an instant hit.
What many do recognise all too well is the difficulty of gathering the energy to get out of bed on Monday mornings in order to face the week ahead. Many bosses argue that starting off the week in person in the office creates good energy. However, plenty of employees beg to differ.
A paper published by the Journal of Applied Psychology, found that people tend to be more ill-mannered on Mondays, and grow more polite as the week unfolds. The authors have diagnosed a new condition, Mondayitis, which is defined. as “a systemic illness with collections of symptoms including tiredness, light-headedness, dry mouth and headache”. These symptoms typically appear on the first working day after a period off work, which could be a weekend or a longer holiday. They can lead sufferers to call in sick, decide to work from home or, if they do show up in the office, come across as detached (冷漠的) and unavailable. Mondayitis appears to be infecting other days of the week.
However, the covid-19 pandemic has led many people to re-evaluate their work-life balance. A lawyer in London who spends weekends working on cases likes to ease into the formal workweek with an elegant breakfast in a fancy restaurant. A broader movement is promoting the idea of a four-day work week, one arrangement of which would make Monday part of the weekend. Less ambitiously, and more realistically, asocial-media campaign for “bare-minimum Mondays” argues for a gentle start to the week.
You may have prepared or merely enjoyed a more elaborate meal than a sandwich. You may have gone for a walk in the park or simply lay in bed. Either way, you almost certainly cleared your head. When revived and spirited, you will have a fresh start.

Whatever its origins, once the seed of the fear takes root, it may grow by
9 . No matter how friendly your tone is or how honey-sweet you are in a conversation, when you start your sentences with one of these words (or both), the message to your recipient is “You are wrong.”
These words don’t say, “Let’s discuss this” or “I’d love to hear what you think about this” to people. They say. “You are wrong and I am right.” If your conversation companion is also eager to win at any cost, you will have a potential battle on your hands. The result?
Are you interested in a little test to see how competitive your co-workers are? Try this. For one week, keep a scorecard of how many times each person uses “No” or “But” to start a sentence.
Stop trying to defend your position and start monitoring how many times you begin remarks with “No” or “But”.
| A．Why do people like saying this? |
| B．I use this technique with my clients. |
| C．What are these conversation stopping words? |
| D．Nothing more can happen that will be productive. |
| E．It’s human nature to like being accepted and recognized. |
| F．You will be shocked at how frequently these words are used. |
| G．Pay close attention to when you use these words in sentences. |
