Remember books? They were those pieces of paper with words printed on them【C1】______in between two, sometimes,【C2】______covers. People bought them, and people borrowed them, but,【C3】______people used to read them. And then came screens. Six years into the【C4】______rise of mobile, half of American adults own a smartphone; over a third owns a tablet. Now, I"m joking about the end of books, but it"s easy and tempting to【C5】______that screens will continue their【C6】______on words and paper-bound books will be at the【C7】______of vanishing. But if you take a hard look at the data, it"s not the end of print. Not by a long shot. 【C8】______years, there hasn"t been a more【C9】______technology for capturing the hopes and the fears of new parents than the tablet. Touchscreens are so easy to【C10】______that babies can use them and learn at younger ages than we thought possible—or babies can use them and use them and use them and lose out on other skills. We just don"t know what this does【C11】______young brains. All we know is we"re【C12】______a generation that sometimes finds magazines more【C13】______than iPads. Parents, of course, can"t not know. Or, if they really can"t, then they don"t want to take any【C14】______. And that"s why it"s not at all【C15】______that the vast, vast【C16】______of parents prefer reading printed books to their young children. Pew Research found that 94 percent of parents think it"s important to read print books to their children. Print【C17】______isn"t going away soon.【C18】______more people prefer e-readers, some would still rather read print. Books will become "luxuries". But, of course, the real test will come in the next few years when we see what kids who have been using tablets since before they could walk prefer to read. Print is in a long, slow【C19】______that feels like a death spiral, but isn"t quite so. For now, at least, the end of print is a long way off, even if kids these days can"t【C20】______how to turn the page.
单选题
【C1】
【正确答案】
C
【答案解析】解析：此处需填过去分词作pieces of paper的后置定语。从后面的between two．．．covers(在两张……封面之间)可以看出，这里解释什么是书。主语They指代第一句的books。通常书是包在封面内，C项packed意为“被包装”，语义符合。
