《The Kite Runner》The second day
"Go on,now," he'd say. "This is grown-ups' time. Why don't you go read one of those books of yours?" He'd close the door, leave me to wonder why it was alwaysgrown-ups' time with him. I'd sit by the door, knees drawn to my chest.
Sometimes I sat there for an hour, sometimes two, listening to their laughter,their chatter.
“走开，现在就走开”他会说，“这是大人的时间，你为什么不回去看你自己的书本呢？”他会关上门，留下我独自纳闷：何以他总是只有大人的时间？我坐在门口膝盖抵着胸膛，坐上一个钟头，有时两个钟头，听着他们的笑声，他们的谈话声。
PS：原来的我也是有着相同的疑惑

加州大学伯克利分校一组研究人员在硅上生长了一种1纳米厚的超薄材料，具有铁电性（ferroelectricity），而且效果实际上比厚几纳米的材料强，这是铁电领域的“根本性突破”。

该材料仅相当于两个原子构造块的大小，因此可以以较低的能量有效驱动更小的设备。

这一发现可能创建更多高级电池和传感器，为计算机存储器和逻辑芯片领域也带来了希望。

在仅1纳米厚的薄膜中发现铁电意味着，这些存储单元可以按比例缩小到以前认为不可能的尺寸。

研究发表在Nature上。

#人生力量阅读计划#我想分享的书是《安妮日记》。分享理由：读《安妮日记》是因为英语课上学了一篇很美的文章选自于此：I wonder if it's because I haven't been able to be outdoors for so long that I've grown so crazy about everything to do with natrue.I can well remember there was a time when deep blue sky, the song of birds, moonlight and flowers could never have kept me spellbound, that's changed since I came here.因为句子写的太美了，以至于我到了大学还能熟背这一段。《安妮日记》写满小女孩安妮对生活的热爱，对友情、亲情、爱情的渴望，想念安妮。
