Passage Two Born without sight, 7-year-old Lucas Murray used to be so afraid of walking that he wouldn’t take a step without his parents. He wouldn’t walk on a bumpy surface. But now, Lucas has become more mobile than his parents ever imagined, running with friends, playing basketball and jumping on a (蹦床)―all on his own. The incredible change is owed to a technique called echolocation, similar to the method used by dolphins and bats, that allows Lucas to paint a picture of his surroundings using the sound he creates himself. To "see" the world around him, he dicks his tongue and listens to the echo that bounces back. From the sound, he can make out the location, depth and shape of objects around him, allowing him to (导航) even unfamiliar areas. Though it’s estimated that only about 5% to 10% of the blind population now uses a (声呐系 统)-type approach, the Murrays hope it could someday become as common as the cane. Two years ago, Daniel Kish, a blind psychologist who has practiced the technique since childhood and has been teaching it for more than 15 years, traveled to the Murrays’ hometown and worked with Lucas for four days, teaching him not just echolocation, but also convincing Lucas and his parents that blindness doesfft need to be a limiting condition. "You have to let go, and it’s the hardest thing in the world;’ said Sarah Murray. When Kish suggested the family let Lucas walk along the shore on his own, she said, "It was frightening. And Lucas found it frightening too:" But after the family overcame the initial fear, Lucas made rapid progress. He learned how to detect different-sized bowls and cardboard panels by clicking to navigating grocery stores entirely on his own. In addition to clicking, Lucas also uses a white cane to find his way. "He likes exploring things, and he likes climbing things" his mother said. "He’ll go up the elevator. That wouldn’t have been believable in a million years:’ She said the technique is second nature to him now.It can be inferred from the passage that ______. A. it is only human nature to imitate the animal behaviorB. by using the echolocation, Lucas’ action will no longer be limitedC. Daniel Kish helped Lucas with the sonar-type approach because he is blind tooD. the hardest thing to learn something new is the fear to take the first step

题目解答
答案
D
解析
文章讲述了7岁的Lucas Murray，一个天生失明的孩子，通过一种叫做回声定位的技术，学会了如何“看到”周围的世界。这种技术类似于海豚和蝙蝠使用的回声定位方法，Lucas通过发出声音并聆听回声来判断周围物体的位置、深度和形状。
步骤 2：分析关键信息
文章提到，Lucas的父母最初非常担心他独自行动，但经过Daniel Kish的指导，Lucas克服了最初的恐惧，学会了如何使用回声定位技术。Kish是一位盲人心理学家，他从童年就开始使用这种技术，并且已经教授了超过15年。
步骤 3：推断正确答案
文章中提到，Lucas的父母最初非常害怕让他独自行动，但最终他们克服了这种恐惧。这表明，学习新事物时，最大的障碍往往是最初的恐惧。因此，选项D是正确的。
