A.Dutch cyclist who says he was scheduled to be on both Malaysia Airlines flights MH370 and MH17—only to switch his tickets at the last minute—knows he’s lucky to be alive but has decided to stop speaking publicly about it. Maarten de Jonge, a 29-year-old rider for the Tereng-ganu team in Malaysia, said in a statement on his website that he’s been inundated (使应接不暇) with media requests since talking about his fortunate change of plans. “I’m frankly overwhelmed (顾不过)by the number of requests,” Jonge saiD. “What has happened is terrible; so many victims, that’s a horrible thing. From respect for the victims and their families, I do not think it appropriate to tell my story.” Officials say 298 people ——189 of them are Dutch citizens—were killed when Malaysia Airlines Flight MH17 was struck by a surface-to-air missile along the Russia-Ukraine border. While Jonge said he was fortunate he decided not to take the flight at the last moment, his story is ultimately(最终) nothing compared to the misery so many people are experiencing. Attention should be paid to the victims and survivors. Wish everyone affected by this disaster a lot of strength. The cyclist was planning to travel back to Knala Lumpur on Flight MH17 on July 17 after competing in last month’s National Championship Road Race in the Netherlands, but told a local television station he decided to save money by flying through Frankfurt insteaD. According to The Daily Telegraph, Jonge was scheduled to be on Malaysia Airlines Flight MH370 from Kuala Lumpur en route to Beijing in March, but switched his ticket to avoid a stopover. The flight disappeared from radar and has yet to be founD. “I could have taken that one just as easily,” Jonge said, according to RTV Oost. “It’s inconceivable (不可思议的). I am very sorry for the passengers and their families, yet I am very pleased I’m unharmeD.” According to his website, Jonge, who finished 35th at the Dutch cycling event, was still planning to fly to Malaysia yia Frankfurt on Sunday. “I have been lucky twice,” he saiD. “You should try not to worry too much because in that case you won’t get anywherE.” 24. Why did Jonge not want to tell his story anymore? A. To not to be famous. B. To prevent reporters from interrupting him. C. To help the victims and their families. D. To respect the victims and their families. 25. Why did Jonge change Flight MH17? A. He had another match at that timE. B. He didn’t want to have a stopover. C. He was late for the flight. D.
