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.

However, without warning, my strength was running out.

I whispered, “I’m so sorry I disappointed you, Dad.”

During the summer before Patty entered fifth grade, she decided to try a new sport. Swim training was nearly over and Patty was the fastest swimmer in her age group. She had always been the best. The neighborhood was offering a one-week tennis training course. Patty and her friend Darla got permission from their parents to join.

On Saturday morning, Darla’s mom took the girls to a store and bought them each a good, used tennis racket. “If you girls stick to tennis, then we’ll talk about a new racket. These will do for now.” The girls were excited about their new purchases. On Monday morning, at 7:00 a.m., Patty’s mom woke her up. “It’s time for tennis!” Patty covered her face. “Mom, it’s too early!” She made great effort to get out of bed and down to the breakfast table. Patty finished breakfast and ran to Darla’s house, then they walked to the court.

Mrs. Cane, the tennis coach, lined everyone up and started with the basics. After that, Mrs. Cane tirelessly taught them to practice their forehand and backhand. By the end of the week, Patty had made impressive progress. Mrs. Cane commented that Patty had lots of potential. Darla, on the other hand, was struggling. The other teenagers were having a tough time of it, too. Patty was the only one who seemed to get somewhere.

Since then, Darla had always been out in the August heat, practicing her serves or hitting the ball. Patty wasn’t really interested. She felt she was such a “natural” for tennis that she really didn’t need to practice. By the end of the summer, Darla began to get the hang of it. She joined a neighborhood junior tennis team. There would be matches every Thursday. Patty wanted to join as well, but she didn’t want to miss her favorite TV show. She told herself that she would join it when she got some free time. If Darla had fun, she would join the team in the spring.

The week before school started, Mrs. Cane held another training course.

Patty couldn’t stop thinking of her poor performance on the way home.

Dave had loved basketball for as long as he could remember and he had never had a day without playing it. At primary school and junior high school he joined basketball clubs, attended training programs and watched basketball games, from which he learned the moves of the star players, wishing to play in a professional team like them and shine on the court.

Now as a senior high school student, however, his dream of becoming a professional player was dimming (变暗) because he was only of average height. He had to give up the hope of joining the school team. The guys on the school team were all tall boys who played matches and won honors for the school. They were like heroes. Dave watched them play and cheered them but he knew he would never be one of them.

Dave felt it a pity not to be tall enough, but this didn’t stop him from pouring his passion into basketball. He just played for the love of the sport. He played in the school gym with other boys or by himself every day, even during holidays and weekends, when it was open for two hours in the morning. He enjoyed every minute on the court making every effort to play better.

It was one Saturday morning. Dave was playing in the gym by himself, as all the other boys were busy with other weekend affairs. Then he noticed a tall boy approaching. It was Lankas. Everybody knows him as captain of the school basketball team. “Hi, Lankas,” Dave greeted him. “My name is Dave.” “Hi, Dave,” Lankas replied as he got closer. “Nice to see you here. Do you need an opponent to play against?” Dave was shocked, frozen right there, unable to believe his ears but somehow, he answered, “Why not?”

6 . Working out for 30 minutes every day “might not be enough” to counter the health issues created by long time sitting, according to a sweeping new study.

The new study, unlike the past ones that examined sitting and formal exercise separately, ignoring light activities, involved 3702 people to find out how those all affected people’s health indices(指数).

With the data collected, researchers characterized people by how they moved. The first group dutifully exercised for a half-hour and then sat, almost nonstop, for more than 10hours a day. Another group similarly worked out for 30 minutes and sat for long hours. But, in between, they rose often and took walks around, spending time in light activities like fetching another cup of coffee. The third group sat, uninterrupted, for up to 10 hours, but also collected an hour of exercise most days. The final group, which the researchers named “the movers,” exercised about an hour most days, while also moving lightly for about two hours more.

When the researchers cross-checked these groups against people’s current health data, the first group had the worst indices. On the contrary, the other groups were all better off and to about the same extent, with relatively improved blood sugar control and cholesterol(胆固醇) levels and about 8 percent less body fat than the first group.

“A single 30-minute, daily workout ‘might not be enough’ to reduce the downsides of long time sitting,” said Vahid Farrahi, the lead author of the new study.“In addition to a brisk(轻快的) workout, we need to move lightly and often, cleaning, taking the stairs, taking a walk in the halls or just not remaining still.”
