I competed in the high jump and came the second. Then I joined the 100-meter relay. The runner worked together and got the first place.

While watched these matches, we felt so exciting to see the players struggling hard for the honor of our class.

When the sports meeting ends, the players had a photo take with their medals. I found the sports meeting real unforgettable.

4 . “Tennis-I'm saying goodbye.” With these words, Russian tennis superstar Maria Sharapova, 32, has announced her retirement.

“How do you leave behind the only life you've ever known?” she asked herself. Several reasons played a role in Sharapova leaving the tennis court for good. Over the last couple of years, she's dealt with an injury in her right shoulder and inflammation(炎症) in her forearms that may have prevented her from returning to top form. In more recent news, the death of her longtime friend, US basketball legend Kobe Bryant, also played a factor in her decision to retire.

“As I think you've seen throughout my career, my perseverance has been my greatest tool, my greatest strength,” Sharapova said in an interview. “But I've started feeling that it was becoming a weakness, because the stubbornness was keeping me going for wrong reasons.”

Sharapova rose to stardom(明星身份） at age 17 when she won Wimbledon in 2004. She won a total of five Grand Slam singles titles. She also earned the Fed Cup title in Russia in 2008 and an Olympic silver medal in singles in 2012, among many other accomplishments.

For 16 straight years from 2004, Sharapova was the world's highest-earning female athlete, according to Forbes. Off the court, she made millions of dollars from companies such as Evian and Nike, as well as starting her own candy company. “Tennis showed me the world-and it showed me what I was made of,” Sharapova wrote on Facebook on Feb 26. “It’s how I tested myself and how I measured my growth. And so in whatever I might choose for my next chapter, my next mountain, I'II still be pushing. I’ll still be climbing. I’ll still be growing. "

The football season was almost over. Sally had been playing football all summer. She really enjoyed running around with the other players in her bright orange uniform, chasing the black and white ball across the grassy field. As much as shewed, though, Sally still had not scored one single goal.

Before each game, they had a practice session. The coach showed Sally and her team how to pass the ball to each other and take shots at the goal. Sally was pretty good at passing the ball, but even during practices, she couldn't kick the ball past the goalkeeper. She wondered if she should quit football and join a different club.

“Don’t give up,” said the coach. But it was half-time, and Sally was feeling frustrated (沮丧). She was trying! Every time she got a chance to kick the ball, it would go in the wrong direction or a player from the other team would take control of it. She sipped at her cola and pouted (撅嘴).

The break was over and the referee blew his whistle to start the game again. The two teams walked back onto the field, both determined to win. Sally bent, tied up her shoelace and heard her mother whisper in her ear. “Stay focused. Keep your eyes on the ball. Look for an opportunity to get the ball. You can do it.”

Sally stood up and took a deep breath. Even if she didn't get one goal all summer, she knew that she had tried her best. That was something to be proud of. So she smiled at her mother and headed to her position. The whistle blew, and the game continued.

The score was tied with one goal each. The green team was pretty good, but Sally's orange team was fast. The girls' ponytails bounced as they ran, with many feet kicking frantically (拼命地) at the ball when it came near them. It was a rather boring game and Sally's heart was no longer in it.
