阅读下列短文，从每题所给的四个选项(A、B、C和D)中选出最佳选项。Working for a big company in London on a salary (薪水)of over £100, 000, you might expect Grayden Reece-Smith to have a luxurious (奢侈)lifestyle, going on expensive holidays or driving a sports car around south London, where he lives. In fact, the 28-year-old leads a very different life from his colleagues. He gives away everything he earns over £42, 000–a number that he thought he could comfortably live on.
Over the past five years, Reece-Smith has handed over more than £250, 000 to organizations such as International Care Ministries, which helps poor families in the Philippines, and the Against Malaria Foundation. He is part of a growing number of young people described as "influential altruists". Influential altruists donate regularly to a charity which they think will have a great impact(影响). Some change careers to make more money, which can then be given away.
Reece-Smith considered working in the charity after graduating from university, but thought that he could make a bigger difference by donating a large part of his salary. He had volunteered as a teacher at a school in Tanzania, but then realized that earning and giving would be more effective. "The cost of my flights there could have paid the salaries of two teachers for an entire year, " he says. Instead, he could "stay at home, living a nice life and still make a huge difference in the world".
He is not mean with money-last year he went to Cuba on holiday, and spent several thousand pounds on a new sofa. But his lifestyle isn't as luxurious as some of the people he works with. "I usually don't buy supermarket-branded food products, but I don't own a car. Other people on my salary might have a bigger house. Some of my colleagues have four-bedroom houses, but we only bought what we needed-a two-bedroom flat. £42, 000 is more than enough to live on and still save, " he says.
