考点：考查非谓语动词的用法。
点评：本题难度适中。主要考查的是非谓语的一些最基本的用法。但是，题目的设置注重了情景化和结构复杂化，加大了考生对题干句的理解难度。这里考生容易误选A。

It seems that every week someone becomes “the first” or “the youngest” or even “the first married couple” to do something that doesn’t seem to be very useful to the rest of us.
Why do they do it? Don’t they have better things to do with their time and money? And why should I be interested anyway? Human beings have already climbed the highest mountains, sailed across the oceans and flown around the world. Many of these things were done a long, long time ago. There just isn’t anything left to explore nowadays. I suppose there’s still a lot of the universe left, and the bottom of the ocean is still a bit of a mystery, but you need a lot of technology to explore areas like that. So, those people who feel the need for adventure can only do things that have been done before.
In May of this year a British man became the first person to walk alone from Canada to the North Pole. Personally, if I wanted to visit the Arctic, I’d rather go as a tourist on a cruise ship, with a helicopter trip to the North Pole included in the price. But OK, this man decided that he wanted to walk. The problem was that he went in the spring when the ice begins to melt and break up. So he got stuck on a longely piece of ice and a plane had to be sent in to rescue him.
These sorts of rescues are making many Australians angry with these record breakers. People trying to break sailing or rowing records get into trouble in the seas. So the Australian navy has to send ships to save them and this costs the government millions of dollars. I suppose we can’t just leave them to drown but we should give the bill to the people who are rescued.
