未分类题The happier you are, the better, right? Not necessarily. Studies show that there is a darker side to feeling good and that the【C1】______of happiness can sometimes make you less happy. Too much cheerfulness can make you deceivable, less successful—and thats only the tip of the iceberg. Happiness does have【C2】______. It can protect us from stroke and from the common cold, makes us more【C3】______to pain and even【C4】______our lives. Yet, June Gruber, a psychologist warns that its important to experience positive moods in moderation. She compares happiness to food:【C5】______necessary and beneficial, too much food can cause problems;【C6】______, happiness can lead to bad outcomes. 'Research indicates that very high levels of positive feelings【C7】______risk-taking behaviors, excess alcohol and drug consumption, overeating, and may lead us to【C8】______threats,' she says. How else can excessive joy, or having lots of positive emotions and a relative absence of【C9】______ones, hurt you? First, it may【C10】______your career prospects. Psychologist Edward Diener, known for his happiness research, and his colleagues analyzed a variety of studies, and discovered that those who early in their lives reported the highest life【C11】______years later reported lower income than those who felt slightly less【C12】______when young. Whats more, they【C13】______school earlier. Included in the studies was one【C14】______a group of American college freshmen who in 1976 claimed to be very cheerful.

未分类题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, Im joking about the end of books, but its 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, its not the end of print. Not by a long shot. 【C8】______years, there hasnt 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 dont know what this does【C11】______young brains. All we know is were【C12】______a generation that sometimes finds magazines more【C13】______than iPads. Parents, of course, cant not know. Or, if they really cant, then they dont want to take any【C14】______. And thats why its 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 its important to read print books to their children. Print【C17】______isnt 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 isnt quite so. For now, at least, the end of print is a long way off, even if kids these days cant【C20】______how to turn the page.【C1】A．sealedB．containedC．packedD．installed
