单选题. "Deep reading"—as opposed to the often superficial reading we do on the Web—is an endangered practice, one we ought to take steps to preserve as we would a historic building or a significant work of art. Its disappearance would jeopardize the intellectual and emotional development of generations growing up online, as well as the preservation of a critical part of our culture: the novels, poems and other kinds of literature that can be appreciated only by readers whose brains, quite literally, have been trained to understand them. Recent research in cognitive science and psychology has demonstrated that deep reading—slow, immersive, rich in sensory detail and emotional and moral complexity—is a distinctive experience, different in kind from the mere decoding of words. Although deep reading does not, strictly speaking, require a conventional book, the built-in limits of the printed page are uniquely helpful to the deep reading experience. A book's lack of hyperlinks (超链接), for example, frees the reader from making decisions—Should I click on this link or not? —allowing her to remain fully immersed in the narrative. That immersion is supported by the way the brain handles language rich in detail, indirect reference and figures of speech: by creating a mental representation that draws on the same brain regions that would be active if the scene were unfolding in real life. The emotional situations and moral dilemmas that are the stuff of literature are also vigorous exercise for the brain, propelling us inside the heads of fictional characters and even, studies suggest, increasing our real-life capacity for empathy(认同). None of this is likely to happen when we're browsing through a website. Although we call the activity by the same name, the deep leading of books and the information-driven reading we do on the Web are very different, both in the experience they produce and in the capacities they develop. A growing body of evidence suggests that online reading may be less engaging and less satisfying, even for the "digital natives" to whom it is so familiar. Last month, for example, Britain's National Lite-racy Trust released the results of a study of 34,910 young people aged 8 to 16. Researchers re-ported that 39% of children and teens read daily using electronic devices, but only 28% read printed materials every day. Those who read only onscreen were three times less likely to say they enjoy reading very much and a third less likely to have a favorite book. The study also found that young people who read daily only onscreen were nearly two times less likely to be above-average readers than those who read daily in print or both in print and onscreen.1. What does the author say about "deep reading"?
