The basketball court was filled with eager students and cheerleaders were waving their pompoms at the stands. Excited cheers could be heard from all sides of the court. My teammates and I got fully prepared for our basketball competition. Our hearts were pounding in expectation of the competition ahead.
“And let’s all welcome the Blue Team!” the emcee (主持人) announced through the microphone. All of us marched in proudly as everyone cheered at the top of their lungs. “And welcome the Red Team!” the emcee announced, and the Red Team came in. We were astonished to see that the Red Team was filled with tall and strong members! We were trembling with fear as we walked slowly towards the centre of the court. As we were short of teammates, our confidence in winning wavered (减弱).
The judge threw the ball and the other team quickly caught it! The ball danced between their hands. Our defence seemed to be in slow motion compared to the Red Team’s swiftness. Soon, the other team scored!
We were losing the match as time passed. To make matters worse, our star player, Tom, even tripped and fell, hurting his ankle! We were losing hope as our best player was gone. Just then, our captain called for a time-out. On the bench, our captain announced that this would be his last match. “Come on! Don’t give up! I want to win one last trophy (奖杯) before I quit. Let’s do it!” he insisted, giving us a wide smile. Hearing this, our team held our fists tightly. We were focused on winning this match and making our captain proud! The judge threw the ball once more. I jumped as high as I could and caught the ball. I ran as fast as lightning and scored. Our opponents were nervous but they still scored a few goals to catch up. A few minutes later, we were neck to neck, locked in a tie.

8 . Many people changed residences and are eager to get familiar with their new neighbors. Here’s a quick refresher on making the most of neighborhood relationships.
Begin at the beginning. Building good neighborly relationships starts when you or someone else moves into the area. If a new neighbor moves in, be proactive (主动的) and welcome them to the neighborhood.
Be inclusive. If you are hosting a large party, consider extending invitations to your neighbors. During the holiday season, remember the people next door with a card, a homemade goodie, or an offer of assistance. Give without expectations.
Allow people to be human.
Accept it. If you have tried your best to resolve a conflict without success, let it go. Sadly, some people won’t like you whatever you do. And you aren’t going to enjoy some people.
A.Maintain your space |
B.Be the first to stop by and say hello |
C.It’s easier to accept it and move on |
D.Everyone has a bad day now and then |
E.Take steps to ensure it won’t happen again |
F.Let others know you are thinking of them |
G.Some neighbors are more easygoing than others |
9 . Researchers at the Indian Institute of Technology (IIT) Madras have been working on a fascinating new way to identify people: using the ways of their breath. This idea could change how we unlock our phones and access secure places.
The key to this technology lies in the way we breathe out. Every person has a unique way of breathing air, which creates specific turbulence (涡流) patterns. The IIT Madras team, led by Prof. Mahesh Panchagnula, has developed a method of catching these unique patterns and using them as a biometric (生物特征识别的) signature, similar to how fingerprints are used today.
They conducted tests with breath samples from 94 people and found that their system could correctly confirm the person’s identity with an impressive accuracy of 97%. However, when it came to identifying someone without knowing who they were beforehand, the accuracy was around 50%. This means the technology is great at confirming if someone is who they claim to be, but it still needs improvement in recognizing people without any prior information. What makes this research exciting is its potential beyond just unlocking phones. It could play a significant role in personalized medicine. Since the way we breathe can give insights into our health, this technology could help doctors tailor treatments to individual patients more effectively.
In a similar study at Kyushu University in Japan, researchers developed an artificial system that identifies people based on how their breath smells. This system showed a high accuracy rate of 97.8% in identifying individuals. However, this method currently requires people to fast (禁食) for six hours before testing, indicating that it still needs to be improved to be more practical for everyday use.
These advancements in using human breath for identification are not just about adding another cool feature to our smartphones. They represent a significant step forward in biometric technology, which could have far-reaching implications in security, medicine, and personal technology. This research at IIT Madras and Kyushu University is pioneering a new way of using the unique patterns of our breath for identification purposes, potentially revolutionizing (变革) how we interact with technology and receive medical care.

10 . “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.
