【正确答案】People say life is one fat book. That being the case, more than half of our writers are only critics. Having acquired the skills of a critic, they glance through no more than a few pages before they make loads of judgments about the book. A review is finished and done. However, some people in this world read books for reasons other than having to write critical appraisals or commentaries. Carefree and relaxed as freelancers, they casually scribble a few words, a question, or an exclamation in the margin—like those headers in Chinese classics, or marginalia in foreign books, they jot down bits and pieces of notes written in a desultory fashion. These are not their impressions of the whole book. Since they make notes whenever a thought pops up, they might overdo their point, or they might contradict themselves later. But they couldn't care less as they only do it for pleasure, unlike the critics whose main mission is to provide guidance for the reader and offer criticism to the author.
