3. You’re Either a Morning Person or a Night Owl (and Morning People Are More Productive)
3. 你要么是個(gè)早起的鳥(niǎo)兒，要么是個(gè)夜貓子（且早起的人效率更高）

Most people think of themselves as either morning “l(fā)arks” or night owls, but there’s more to sleep cycles than that. People have different energetic times during the day that aren’t necessarily tied to our preference for sleeping late or getting up early. And you know that saying “the early bird gets the worm”? While our society—the workplace and school systems—seem to reward morning people, night owls can be just as productive and creative as their counterparts. In fact, doctors say schools should start later in the day for the health of students, who aren’t getting enough sleep. (I’d be up for later workday start times too.)
大多數(shù)人都認(rèn)為自己不是早起的鳥(niǎo)兒就是夜貓子，但睡眠周期不只是這些。人們一天之中精力充沛的時(shí)間各不相同，與喜歡睡得晚一點(diǎn)或早一點(diǎn)關(guān)系并不大。你知道有句俗話叫“早起的鳥(niǎo)兒有蟲(chóng)吃”嗎？我們的社會(huì)——工作單位和學(xué)校，似乎都鼓勵(lì)早起，但是夜貓子可以像早起的人一樣高效且富有創(chuàng)造力。實(shí)際上，醫(yī)生說(shuō)現(xiàn)在的學(xué)生睡眠不足，學(xué)校應(yīng)該把上學(xué)的時(shí)間推遲一點(diǎn)，這樣有益于學(xué)生健康。（我覺(jué)得也應(yīng)該把上班的時(shí)間推遲一點(diǎn)。）
