        梅雨潭闪闪的绿色招引着我们;我们开始追捉她那离合的神光了。揪着草,攀着乱石,小心探身下去,又鞠躬过了一个石穹门,便到了汪汪一碧的潭边了。瀑布在襟袖之间;但我的心中已没有瀑布了。我的心随潭水的绿而摇荡。那醉人的绿呀,仿佛一张极大极大的荷叶铺着,满是奇异的绿呀。我想张开两臂抱住她;但这是怎样一个妄想呀。——站在水边,望到那面,居然觉着有些远呢!这平铺着,厚积着的绿,着实可爱。她松松的皱缬着,像少妇拖着的裙幅;她轻轻的摆弄着,像跳动的初恋的处女的心;她滑滑的明亮着,像涂了“明油”一般,有鸡蛋清那样软,那样嫩,令人想着所曾触过的最嫩的皮肤;她又不杂些儿尘滓,宛然一块温润的碧玉,只清清的一色——但你却看不透她!我曾见过北京什刹海拂地的绿杨,脱不了鹅黄的底子,似乎太淡了。我又曾见过杭州虎跑寺旁高峻而深密的“绿壁”,重叠着无穷的碧草与绿叶的,那又似乎太浓了。其余呢,西湖的波太明了,秦淮河的又太暗了。可爱的,我将什么来比拟你呢?我怎么比拟得出呢?大约潭是很深的、故能蕴蓄着这样奇异的绿;仿佛蔚蓝的天融了一块在里面似的,这才这般的鲜润呀。——那醉人的绿呀!我若能裁你以为带,我将赠给那轻盈的舞女;她必能临风飘举了。我若能挹你以为眼,我将赠给那善歌的盲妹;她必明眸善睐了。我舍不得你;我怎舍得你呢?我用手拍着你,抚摩着你,如同一个十二三岁的小姑娘。我又掬你入口,便是吻着她了。我送你一个名字,我从此叫你“女儿绿”,好么?

As the CEO and founder of Apple, Jobs hardly talked about his personal life in public. Here are some specific things.

1Early life and childhood  Jobs was born in San Francisco on February 24, 1955. He was adopted(收养) shortly after his birth by a couple(夫妇) named Clara and Paul Jobs. He grew up in California. Later in life, Jobs discovered who were his birth parents. However, Jobs only had some communication with his birth mother.

2 College dropout After leaving high school, Jobs entered Reed College in 1972. Jobs stayed there for only one semester, because his parents couldn’t afford his education.

3 An important date Jobs actually missed a meeting because of his first date(约会)with his wife, Lauren Powell. He said, “I was in the parking lot (停车场)with the key in the car, and I thought to myself, ‘If this is my last night on Earth, would I rather spend it at a business meeting or with this woman? ’ I ran across the parking lot, and asked her if she’d have dinner with me. She said yes, we walked into town and we’ve been together ever since. ”

4His sister is a famous author Later in his life, Jobs met up with his biological sister Mona Simpson, the famous author of Anywhere But Here.

5His first daughter When he was 23, Jobs and his high school girlfriend Brennan had a daughter, Lisa Brennan Jobs. He and Brennan never married. Jobs paid for his first daughter’s education at Harvard. She graduated in 2000 and now works as a magazine writer.

    6His fortune As the CEO of Apple, Jobs only took $1 a year, but Jobs leaves behind a vast fortune. In 2011, with $8. 3 billion, he was the 110th richest person in the world, according to Forbes.
