问题     I know cold. And all you Minnesota people may discount me because I am from Phoenix, but trust me, I know cold. I have climbed the highest peak on each continent (the famed Seven Summits) and have skied to both the North and South Poles — a feat known as the Adventure Grand Slam. Each mountain and polar expedition was very different — with the exception of one thing: the cold.
    Of all the remote places I have been, Antarctica — land of the frozen tundra — is perhaps my favorite. It also happens to be the coldest place on earth. The continent is approximately 98 percent ice and 2 percent rock. Temperatures in the winter have reached 128-below. I have been there twice; once to climb the Vinson Massif and once to ski six-hundred miles from the edge of the western Antarctic ice shelf all the way to the South Pole. "Why would you want to suffer like that" is a question I get all the time. And sure, there are times when you are feeling like you want to take a break from the frigid conditions and go inside the lodge and get a cup of hot cocoa... but you can’t. There is no ski lodge in the middle of Antarctica. There’s just you, your 1501b sled which is harnessed to your waist (containing all of your gear and supplies), your teammates (unless you are on a solo trip — no thanks) and the cold. So you make peace with the sub-zero temperatures, because you’re going to be in them for the better part of two months.
    So thinking back on my experiences here’s why you should be okay with a couple of days of polar vortex — because 1) you can go inside, and 2) because it makes you smarter — or at least smarter than the warm weather does. Yep. Good news for those in cities affected by the vortex: cold weather can actually be really good for you. Not just because you burn more fat when it’s cold, but because your brain works better when it’s cold. According to an article by Adrian Ward that appeared in Scientific American, it takes more energy to cool your body when it’s hot than it does to warm it up when you’re cold. The energy comes from glucose... which is also necessary for the brain’s mental processes. So basically, cooling off when it is hot uses more glucose than warming up when it’s cold; thus leaving less available glucose for the brain.
Therefore, we can assume that cold weather is better for the brain. Quick — everyone go take the MENSA test before the temperature warms up again!
What do the mountains the author has climbed have in common?
选项 A、They are all located in the North Pole.
B、They are all located in the South Pole.
C、They have the same elevations.
D、They are all very frigid.
答案D
解析 首段中作者说，自己见识过寒冷，并举了一些例子来进行说明，其中末句指出。作者所爬过的每一座山和每一次极地冒险的经历都各有不同，但是只有一样是共同的：那就是这些地方都很寒冷。选项D)是对原文末句的同义转述，故为正确答案。A)和B)是对原文的错误理解，故排除。文中并未提到这些山峰的高度是一样的，C)与原文不相关，故排除。
