I yawned (打哈欠)as I got off the last step of the bus. I had woken early that morning, and had not been able to sleep on the long ride from Riverside High, thinking about that day’s race, the Eye Opener. I had never raced in a state-wide race before. Over thirty high school teams ran, along with quite a few colleges. The rest of my team and I unloaded the bus, and we relaxed and waited for our race patiently.

“Start warming up,” our coach told us, roughly forty-five minutes after we arrived. After finishing our stretches, we headed over to the starting line, eager for the race to begin.

The starter walked to the middle of the field. “There will be two commands,” his voice boomed, ‘‘Runners set, then the gun. If you hear another shot, return to the starting line to start again. ” My heart raced as I got my legs ready to race.

“Runners set!” the starter shouted Bam! The gun fired, and he rushed out of our way. Adrenaline (肾上腺素)rushed through my body as I raced through the mass of runners. As I rounded the first turn, my schoolmates greeted me with heartening shouts. Then, in what felt like only one minute, I arrived at the one mile mark.

“6’10”, a man declared as I ran by. I tried to ignore him, but my legs began to burn as I realized I had run a mile and still had two to go. I slowed down my pace, for I knew the second mile was the worst of all three. Minutes later, I felt horrible. My legs ached, feeling like lead blocks. My vision was clouded as sweat dropped down into my eyes, and my arms felt as if they would fall off if I swung them one more time. Just as I almost reached my limit, a boy passed me. He also seemed to have lost strength but soon he was a little ahead of me.

I gathered up my strength to speed up but suddenly fell to the ground.

In the last mile, seeing the athletes passing us one by one, I asked the boy to run without me.

4 . Food waste has become a severe problem across the world due to a lack of understanding of how to effectively use food and conserve it. Roughly one- third of the food produced globally is either lost or wasted every year.     1    

Stop Food Waste Day is an international day of action in the fight against food waste. It began back in 2017 by Compass Group, one of the world’s largest food-service companies serving restaurants, cafes, hospitals, schools, and more.     2     On this day, Compass country teams will work together to raise awareness of the critical food waste problem and inspire change.

Stop Food Waste Day aims to educate people about their food waste.    3     Stop Food Waste Day hopes to change the way leftovers are used, so people can take the most significant advantage of what food they use.

The Compass Group focuses the efforts of its mission by teaching their chefs how to track and reduce waste as much as possible. They also seek to donate more than 250, 000 pounds of food each year to local food banks.

    4     Show your support by looking up simple recipes to best use leftovers and fresh produce. Before food shopping, plan ahead by making a list and only buying what you know you’ll use.     5    

Get into the habit of freezing leftovers, instead of throwing them in the rubbish. Besides, help teach people about the benefits of saving food waste.

5 . Does your dog always want to go wherever you’re going and most of the time, this behavior is welcomed?    1    However, if you find your dog doing this too often or if it’s accompanied by other troubling behavior like eating less, going outside less often or interacting less with other family members, there could be potential issues.

    2    Usually, it’s simply out of loyalty and the close relationship that’s been created with its owner, because he or she is the one that provides care and comfort and keeps it safe. However, sometimes, your dog wants to follow you possibly due to something negative.    3    

Dogs are emotional animals and may feel anxious for some reason sometimes. It may take much time and training to help your dog work through what’s causing the problem    4    You’ll have to work with your dog consistently or hire a professional trainer.

One way to stop your dog from following you might be putting it in a secure and reliable area.    5    If your dog spends all of its time with you and you alone, it may express a dislike for being away from you or interacting with other humans or dogs.

6 . People do physical exercise as part of their healthy lifestyle to get stronger and healthier.

There are three basic modes of physical exercise: flexibility exercise helps the human body in general or its part in particular to be able to reach farther and bend better; aerobic exercise helps the body work hard for a long time; anaerobic exercise makes the arms and legs stronger.

It has long been known that exercise is not only good for your body, but also for your mind. According to researchers, gymnasts are more likely to be emotionally stable, football players the most outgoing and swimmers the happiest.

The psychological study, which was carried out by experts, also revealed that sports can also offer clues to a person’s attitude to charity, reading habits and even their voting intentions. Boxers, for example, are most likely to focus on material possessions in life. Meanwhile, runners tend to be outgoing people who love being the centre of attention. Walkers, a group that includes those who enjoy wandering and cross-country races, are least concerned about other people and like doing things by themselves without interruption from others. Those who play chess are confident when they face challenges and trouble. Those who swim tend to be tidy and charitable. However, according to Mind Lab, 61 percent of adults are fond of helping others regardless of their choice of sports.

The results from this study also show that no matter what kind of person you are, there is the right kind of exercise for you.

9 . Natural silence — the kind when you hear nothing but the sound of nature around you — is becoming increasingly scarce. The noise of man-made can be heard even in the remote corners of national parks and deep in the Arctic Ocean.

This is having some troubling effects. In humans, noise pollution has been linked to physical, mental health problems and cognitive impairment (认知功能障碍) in children. In wildlife,it’s disturbing navigation, pairing, communication and can cause hearing loss. “We’re losing the ability to listen to nature without noise pollution,” says sound recordist Matt Mikkelsen. He’s part of the non-profit organization Quiet Parks International, which aims to identify and preserve the planet’s last quiet places.

Recently, this took him to Boundary Waters Canoe Area Wilderness in northeastern Minnesota. No cars, motor boats, electricity or telephone lines are allowed in the one-million-acre area,making it a strong candidate for Quiet Park status. But listening back to the recording, Mikkelsen can hear the low hum (嗡鸣声) of a commercial plane flying far away.

Quiet Parks hasn’t yet decided if Boundary Waters meets its criteria — it’s one of 260 potential sites around the world that the organization is currently exploring. The team will analyze the sound recordings from each location and consider them alongside other data.

In recent years, the world has been getting louder, with cities and towns expanding and an increasing number of noises from cars, airplanes or ships. But during the COVID-19 pandemic (流行病), there has been momentary delay.In2020,global air travel was down by 60% and road transport decreased by almost half. Scientists in Europe found that noise caused by humans fell by up to 50% after lock downs were carried out.

“People enjoyed the silence,” says Mikkelsen. “There were no airplanes in the sky and cars weren’t on the street. It was an incredible thing to be able to hear the world, all of a sudden, free from noise pollution,” he says. Since the start of the pandemic, Quiet Parks says it has experienced a huge increase in interest for quiet places. “I hope that we can take that desire for a world with less noise forward,” says Mikkelsen, “and appreciate the spots we have, where we can go and not experience noise pollution.”
