问题     As you sat across the Thanksgiving table basking in the warmth of family and the aroma of chestnut stuffing, most likely you did not remember the vicious comment your Aunt Jennifer made about you a few years back. You didn’t dwell on Uncle Julio’s unkind reference to your drinking last Christmas or what cousin Duwan said about your girlfriend during that dreadful vacation at the shore. At family holidays, we tend to embrace our relatives even after months or years of not having seen one another, regardless of the quarrels we have had in the past.
    We may chalk up our generous forgiveness to the festive spirit of the holiday, but the real reason has nothing to do with Thanksgiving; it is because of how we humans remember—and forget. Cognitive experts tell us that forgetting is fundamental to how we make sense of the world. Forgetting helps us survive, by making sure we don’t dwell in the past.
In the digital age, that mechanism of our humanity is under threat.
    We all hate when we can’t remember something. We think of it as a bug of the human mind. We don’t realize that by discarding most of the avalanche of details that our senses are bombarded with every day, as well as past wounds, our brain helps us focus on the important things; it lets us see the forest rather than just the trees. We may learn from our failures, but thankfully we also easily forget them.
    Human memories are not fixed; they are reconstructed. We remember more easily what we remember often. More important, we tend to forget memories that don’t fit into our current world vision; our brains discard them as no longer important. That way, we forgive one another (and ourselves) for past transgressions. Thus our memories of most past experiences wither.
    Forgetting misdeeds that we deem no longer relevant is a powerful mechanism; and the best part of it is that it’s built into us. But it also means that operation is thwarted in a world of comprehensive memory, a world in which we are constantly reminded of our past.
    Our ever-improving digital tools record billions of Facebook messages and more than 300 million tweets every day—not to mention our private e-mail accounts, with their photos and videos. Logging our lives is becoming the norm, and having a comprehensive digital memory at our disposal is the default.
    Many people are concerned about what this does to privacy. I am worried about Thanksgiving—the warmth and joy that may be lost when we keep being reminded of every mistake, every quarrel, every disagreement...
    With comprehensive digital memories all around us, forgetting one another’s offenses becomes more difficult; through our digital tools we’ll be alerted to all we thought we had forgotten. This will make it harder for us to forgive.
    In one of his short stories, author Jorge Luis Borges describes a young man who after an accident can no longer forget. He can remember perfectly all the books he has read, but he has been unable to learn anything from them, because learning involves the distilling of abstract thought from detailed memories, after which the latter fade away. Thus it, too, necessitates forgetting. In future Thanksgivings, our data glasses might identify family members through facial recognition, and within a split second, display old e-mails and images, tweets and posts, reminding us in excruciating detail of their (and our) past shortcomings.
    Some say that we’ll adapt by disregarding these digital memories. But it is naive to think that if so directly reminded of earlier quarrels, we’ll be able to put the revived memory aside. Our brain is trained to remember events we thought we had forgotten when given an external stimulus. Automatically disregarding revived memories is as hard as deliberately forgetting things—we can’t do it.
    We need to appreciate and preserve forgetting as a feature of humanity. To do so may require us to adapt our digital tools. Unlike our brains, they can easily be rewired. With the help of the companies that design our online tools, we could let tweets and Facebook comments expire over time. We could choose the photos in our digital libraries we want to remember, and the e-mails we hold dear, as we let the rest slowly disappear, giving us a renewed and much-needed chance to forget.
    This would preserve in the digital age our ability to grow, to learn and to forgive. And it would give us a better shot at having a rancor-free family holiday. That alone would be worth it.
We can learn from the first two paragraphs that________.
选项 A、holidays like Thanksgiving make people forgetful
B、family members always poke unkind comments toward each other
C、forgetting is important to human experiences
D、cognitive experts tell us the meaning of the world
答案C
解析 细节题。根据第二段最后两句可知，遗忘对于我们认清世界万事万物的意义至关重要。遗忘通过确保我们不停留在过去，来帮助我们存活。可见，遗忘对于人类的经历是很重要的，故选[C]。根据第二段第一句可知，是我们大脑的记忆和遗忘机制让我们在节日里与家人团聚时常常忘记彼此之前的过错，而不是节日本身，故排除[A]；根据第一段和第二段第一句可知，作者以感恩节的家庭聚会为典型场景，引出人类的遗忘这一现象，但不能就此推断出家庭成员总是恶意评论对方，故排除[B]；第二段倒数第二句只是提到认知学家告诉我们，遗忘对我们认清世界万物至关重要的意义，故排除[D]。
