单选题 .  How do people become lifelong readers? That's a subject tackled in a new book, Reading in the Wild: The Book Whisperer's Keys to Cultivating Lifelong Reading Habits, by Donalyn Miller, a sixth-grade language arts teacher in Texas who is known as the Book Whisperer.
    After her first book, The Book Whisperer: Awakening the Inner Reader in Every Child, was published in 2009, she began to notice that students whom she had taught to be independent readers in her class moved on to the next grade and suddenly stopped reading.
    "Why then do they still need a teacher to plan their reading lives?" She said she wondered after students who had left her class visited and told her they weren't reading much anymore. That's when Miller realized that the students still did not have "reading role models." They still didn't know how to schedule reading time, or how to pick books on their own.
    So with experienced teacher Susan Kelly, Miller wrote Reading in the Wild: The Book Whisperer's Keys to Cultivating Lifelong Reading Habits, which explains how to cultivate lifelong reading habits.
    Here are the five key habits of lifelong readers.
    Dedicate time to read. They make the best of the moments in their days when they are bored or waiting, and rack up significant reading time by stealing it.
    Successfully self-select reading material. They are confident when selecting books to read and can choose books successfully that meet their interests, needs, and reading abilities.
    Share books and reading with other readers. Reading communities provide a peer group of other readers who challenge and support us. Children read more when they see other people reading.
    Have reading plans. They plan to read beyond their current book. Reading is not a casual, once-in-a-while pursuit.
    Show preferences for genres (体裁), authors, and topics. Yes, children need to read widely and experience a wide range of texts as part of their literacy educations. But lifelong readers express strong preferences in the books they like to read—gravitating toward specific genres, writing styles, topics, and beloved authors.6.  What is Donalyn Miller's new book about? ______
