留几本书在窗台

翁秀美

    ①星期天收拾房间，顺便整理书柜。书大都是新的，买回来还没翻过。有几本落了厚厚的灰，用湿布擦了，随手丢在窗台上晾着。

    ②再进书房时，只觉眼前一亮。迎面窗台上的书随意躺着，有一本斜放在红红的“中国结”上。淡紫色窗纱轻拂过书面，宽大的窗台显得生动明媚。原来，书可以不用整齐地码在书柜里，也可以不用机械肃穆地正襟危坐着。书在窗台上很显眼，淡雅的鲜艳的封面堆叠，有些乱，却是明亮可喜，一进门就入了眼。我的心情也轻松愉快，就想坐下来，细读一番。

    ③这个念头，让我吃了一惊。细致认真地读一本书，是很久以前的事情了。书，曾经是我的最爱。端着饭碗看，躲在被窝里看，连上厕所也是手不离书。最喜黄昏时，端了小凳坐在院子里，看《当代》，看《花城》，不知天黑不觉肚饿，每次被母亲催着赶着进屋还舍不得放下。那会儿，好书，如友。

    ④那一年生病住院，怕闷，带了《宋词三百首》《闲情偶寄》．医院建在山下僻静处，病房夜里不熄灯，正好读书。 字字句句如清水，将五脏六腑涤荡得妥帖舒畅。精神面貌实不像一个病人。出院时，书角已被翻得起毛打卷。好书，胜药。

    ⑤只是不知什么时候，时间长了翅膀，“哧溜”一下就过去了。一天、一月、一年，快得让人招架不住。每天来去匆匆，总有做不完的事情，一天恨不能掰成两天用。日子仿佛是被抽打着的陀螺转个不停，再难挤出时间来读书了。黄庭坚有言：“三日不读书，便觉面目可憎。”想来我早已是面目全非了。

    ⑥坐在窗台，伸直腿，书搁在腿上，慢慢翻看。午后的阳光透过玻璃笼在书页上，文字构建的美妙意象和感觉瞬间渗入全身，心在字里行间跳跃飞翔，喜悦漫溢开来。窗外，天蓝如洗，云作奇峰。这景被窗户框成了画，清新至极。身边的书故人一般围拢着，久违的亲切感油然而生。捧着书坐着，直到最后一缕阳光从书页里消失，暮色在身边聚集，尤不忍释卷。 因为阅读，匆忙枯燥的时间被文字的墨细细研磨了，书香适意怡人。这个下午也变得安静美好，有了回味。其实，日出日落，每天的时间并没有走快一分，是现代生活的快节奏，让我们的神经紧绷了，脚步加快了，也让我们的心浮躁不安。想起时下正流行的“慢生活”观念，提倡慢工作、慢餐、慢运动、慢休闲、慢阅读等，提醒生活在高速发展时代的人们，适时慢下来关注心灵、环境和传统，是多么的重要与必要。是的，即使停一停看看身边的风景，读读手边的书，哪怕是安静地听完一首优美的曲子，也会让单调的生活充满暖暖阳光，使精神舒缓、愉悦、充实。

    ⑦眼前，无意中留在窗台上的书，让我知道，阅读，其实一直是我心里最深切的渴求与向往。留几本书在窗台，以便随时翻阅，在忙碌中休闲一回，给心灵放个假，重新体验读书的乐趣，并且也将改变以往一成不变的生活方式。

    It happens every night—bedtime. But what if you're not sleepy? Should you still go to bed if you are just going to lie there with your eyes wide open? It's a problem that has been around as long as there are people trying to sleep.

    You might be excited by something you did in the day. You might be nervous about what you're going to do the next day. Maybe you don't like sleeping alone in your room. Maybe you have frightening dreams. All of these are possible reasons for your sleeping problem. However, there are some steps you can take to help you solve it.

    One thing that can help is talking to a parent or another trusted adult about what you're worrying about at bedtime. For example, if you're nervous about taking a test, or upset about being teased (被嘲弄) at school, it can really help to tell somebody. Knowing that somebody has heard you can help ease your mind so that you can have a good rest.

    Sleeping in a comfortable bed in a quiet and cool room is a good choice. If there's anything in your room that makes you feel uneasy or anxious at night, like a picture that looks strange in the dark, or a noisy faucet (水龙头) in the bathroom, be sure to ask your parents to move or fix it. Make sure electronics, such as mobile phones or iPads, are kept away from your bed. They can keep you excited, making it harder for you to fall asleep.

    If you are usually restless around bedtime, doing certain things to relax beforehand may help you fall asleep. Try to take more time to wind down by taking a warm bath, or listening to a bedtime story at least 30 minutes before you go to sleep. It also helps to follow a bedtime routine and go to sleep at the same time every night. As a result, your body will get the message that it's almost time to sleep. Your body will know to start feeling tired.

    In order to find the right solution for you, it's possible that you understand what exactly is keeping you up at night. Getting a good night's sleep is worth the time and effort of finding the right solution to your sleeping problem.
