【題目】 On Jan 26, people around the world were shocked to hear of the sudden passing of Kobe Bryant(科比布萊恩特), one of the NBA's most legendary (傳奇性的) players. The 41-year-old, his 13-year-old daughter Gianna Bryant and seven others died when their helicopter crashed in California, US.

People from all walks of life have respected the late basketball superstar — not just for his achievements on the court, but for his genuine(真誠的) personality and the inspiration(激勵) he provided to so many people.

In the basketball world, Bryant ranks among the top players of all time. Fans remember him as the player who helped the Los Angeles Lakers win five NBA championships during his 20-year-long career. He started out as a basketball prodigy(神童) who skipped college and took his talents directly to the NBA: His deadly agility (敏捷) and aggressive tactics(進攻性的策略) earned him the nickname Black Mamba(進攻性極強的一種非洲毒蛇). That's why his competitive philosophy(哲學) is known as the “Mamba Mentality".

“Mamba Mentality is you're going, you're competing(競爭), you're not worried about the end result," Bryant said. “It's all about focusing on the process and trusting in the hard work when it matters most."

Off the court, he was known as a successful businessman, buying stakes(股份) in several companies, including Alibaba and Dell. He also left footprints in the movie industry, winning an Oscar in 2018 with his short film Dear Basketball.

He was also known as a proud family man. His friend, baseball star Derek Jeter, remembered him as such in an essay:“Throughout our friendship, the most meaningful conversations we had — they were always about family."

As the Los Angeles Times noted, Bryant's greatness was cemented(強化) by his skill, hard work and tireless pursuit of victory. His legacy(留給后人的東西) will live on long after his death.
