1 . As with every World Cup, at the 2022 FIFA World Cup in Qatar the players will be using a new ball. The last thing competitors want is for the most important piece of equipment to behave in unexpected ways in the most important tournament of the world’s most popular sport, so a lot of work goes into making sure that every new World Cup ball feels familiar to players.
Between shots on goal, free kicks and long passes, many important moments of a soccer game happen when the ball is in the air. So one of the most important characteristics of a soccer ball is how it travels through air.
As a ball moves through air, a thin layer of mostly still air called the boundary layer (边界层)surrounds some part of the ball. At low speeds this boundary layer will only cover the front half of the ball before flowing air peels (划过) away from the surface. In this case, the wake of air behind the ball is somewhat regular and is called laminar flow. When a ball is moving quickly, though, the boundary layer wraps much farther around the ball. When the flow air does eventually separate from the ball’s surface, it does so in a series of chaotic swirls (不规则气旋). This process is called turbulent flow.
When calculating how much force moving air imparts on a moving object — called drag — physicists use a term called the drag coefficient (系数). For a given speed, the higher the drag coefficient is, the more drag an object feels.
It turns out that a soccer ball’s drag coefficient is approximately 2.5 times larger for laminar flow than for turbulent flow. Though it may seem counterintuitive, roughening a ball’s surface delays the separation of the boundary layer and keeps a ball in turbulent flow longer. This fact of physics that — rougher balls feel less drag — is the reason why dimpled (坑坑洼洼的) golf balls fly much farther than they would if the balls were smooth.

My dad and I had been looking forward to the Stale cross-country race of my senior year of high school, which would be the climax (顶点) of my existence.
I was the fastest runner on my team, and I was supposed to make it into the top fifteen. We had been working towards this race for three years. It was everything to me, and it was everything to my dad. He was a runner and was wild with joy by my success in running. He made it to every race, even flying home early from business trips to see me run. I always listened for his voice, which rang above the crowd-telling me to relax my arms, calling out my time. He pushed me. He cheered for me. He believed in me. We spent countless hours on the sandy canals of Arizona. Breathing in the dust of the desert, the blossoms of the orange trees, and the terrible smell of the dairy farm, we made our way across the city. We pounded miles and miles into our running shoes, marking with every step the path to greatness. It was a journey that was just ours. A dream passed on from one generation to the next.
Then the big day came. It was hotter than normal - too hot. My throat felt like a field of cotton, cracked with the summer heat, as I waited for the gun to fire. I gazed out at the crowd; dozens of familiar faces from church and school flickered across my view. They had come for me. They were counting on me. I saw my dad set his watch, worry and excitement etched across his face. With the sound of a gunshot, the race began.
For the first two and half miles, I felt great. I had never before been so ready for something. The weeks leading up to the race were filled with hard practices and a strict diet. The scorching sun beat upon my back, blinding me with its brilliance. Nothing was going to stop me, though.

Never had she been so nervous before. This competition was of vital importance to her comeback. “If I can win today,” she said to herself, “I can dance on the national stage next month.” Three months ago, her left arm was seriously injured in a car accident. After the medical treatment, she began to recover slowly. She practiced over and over again in order to regain her dancing skills.
“Hi, Mary,” in rushed her friend Jessica “How is your arm? Is it going to influence your performance?”
“I guess it can be tolerated for I am to win the match.” said Mary with a determined look.
“Admirable! But I hear that a girl called Linda is really gifted and strong. She can be your real well-matched competitor. Come on!”
After Jessica left, Mary decided to practice her most difficult spin. “If I don’t try harder, I won’t grasp this chance.” She thought. But her arm began to hurt, making her worried. “Mary, what makes you think you have a chance tonight?” she said to herself. After the pain was gone, she continued to warm up.
A slim girl hurried in and put down an equipment bag on the chair. Then, she took out her dance dress quickly and put it on skillfully. Seeing Mary, she smiled politely and said “Hi, I’m Linda. I am the next one!” Mary nodded in reply but felt uncomfortable. “This is just my competitor. Because of her, I may lose tonight.” Her mind was wandering when Linda let out a scream, “Oh, God, I can’t find my music tape!” Linda searched her bag but in vain. “It may be missing on the way.” With these words, she then rushed out.

I used to be very active in sports and games when I was in primary school. I won the B Division long jump and was a good sprinter (短跑运动员). As a result, I was chosen to represent the school in the long jump and relay events at the District Sports Meet. Before the sports meet, I had put in a lot of hard work and dedication during the training sessions. I woke up early every morning to go for runs and did countless drills to improve my technique. My teammates and I supported and encouraged each other during training, pushing ourselves to do better and achieve our goals.
The meet lasted two days, I had no events scheduled for the first day. So I kept myself busy by watching the others compete. Large tents were provided for the young competitors on one side of the track. Despite being assigned the last tent that was furthest from the track, I made the best of the situation by decorating it with our school colors and creating a supportive atmosphere.
The next day, I was getting ready for my events. The long jump was scheduled for the early afternoon, followed by the 8×50m relay later in the afternoon. I thought I was a pretty good jumper, but as the competition began, I realized I was vastly outclassed. We finished our jumps, and I came in fourth place, just missing out on a medal.
That was disappointing, but I reminded myself that we still had a chance in the 8×50m relay, for which I was assigned to run the fifth leg. The race date arrived. We filed into our assigned spots and prepared for the race. After a tense minute or so, I heard the starter’s gun go off. When the first runners took off, I watched nervously and excitedly as my team runners kept up with the others. As they got closer, I realized we were at least in second place.

________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________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.

8 . Physical education, or PE, isn’t required for all high school students. In some schools, it isn’t offered for some different reasons. But should high school students have physical education? The answer is certainly “yes”.
Today many people don’t do sports. But as is known to all. doing sports is very important for an adult. Teaching teens the importance of a healthy lifestyle and making fitness plans now can help teens put exercise in the first place as an adult.
High school isn’t that easy. Many students are under a lot of stress. Stress can be harmful to a student’s studies and life. Doing sports can help them deal with stress better, helping them live a happier life at school.
The American Heart Association says that 10 million kids and teens suffer from obesity (肥胖). Teens should get 60 minutes of physical activity per day to control their weight and to help their bones get stronger. The increase in activities that don’t get teens to move around, such as computer games, means many teens don’t get their required exercise. PE classes act as a public health measure (措施) to encourage physical activities and help teens have healthy weights.
Not doing sports increases teens’ hazard of developing many diseases. An active lifestyle offers a good way of protection from these health problems. As much as 75 percent of health-care spending goes toward treating medical conditions that can be prevented by lifestyle changes, according to the American College of Sports Medicine.
According to the President’s Council on Fitness, Sports and Nutrition (PCFSN), students who performed five hours of physical activities each week improved their academic (学业的) performance. Students from programs with no physical activity, who used the extra time for classroom study, did not perform better on tests than those who gave up some study time in support of physical education.
1. According to Paragraph 2, what does physical education in high school mean?| A．Making teens attach importance to ęxercise later. |
| B．Removing the stress faced by teens at school. |
| C．Getting teens to encourage adults to exercise. |

10 . A new study has found that braving the cold maybe a good way to help burn off some fat.
The research was carried out by scientists at Canada’s Laurentian University and focused on high-intensity interval training(HIIT). This format has grown in popularity of late due to the fat-burning benefits it brings, and the team set out to explore how temperature might influence its effects.
The study involved 11 overweight adults who took part in two HIIT sessions a week apart. One of these was carried out in a “thermoneutral” environment with temperatures of around 70 °F(21℃),and the other at a cold 32 °F(0℃). The sessions consisted of 10 separate cycling race at 90 percent effort lasting one minute, followed by 90-second “recovery” periods of cycling at30 percent intensity.
After each session, the participants cooled down by gently cycling or walking, ate a nutrition bar before going to sleep and enjoyed a high-fat breakfast the morning after. During these sessions, the scientists monitored skin temperature, core body temperature, heart rate and the amount of oxygen. Blood samples were also drawn to help calculate fat burning rates following the breakfast the next day.
“The present study found that high-intensity exercise in the cold increased lipid oxidation (脂质氧化) by 358 percent in comparison to high-intensity exercise in a thermoneutral environment,”the team writes.
The authors also note that the idea that cold temperatures help us burn more fat during exercise will need further investigation (调查), though the first-of-a-kind study does indicate it’s a possibility worth pursuing.
1. What is good for burning off fat according to the study?| A．Cold food. | B．Low temperature. |
| C．Hard workout. | D．Cycling race. |
