高祖本纪（节选）

司马迁

    初，项羽与宋义北救赵，及项羽杀宋义，代为上将军，诸将黥布皆属，破秦将王离军，降章邯，诸侯皆附。及赵高已杀二世，使人来，欲约分王关中。沛公以为诈，乃用张良计，使郦生、陆贾往说秦将，啖以利，因袭攻武关，破之。又与秦军战于蓝田南，益张疑兵旗帜，诸所过毋得掠卤，秦人憙，秦军解，因大破之。又战其北，大破之。乘胜，遂破之。

    汉元年十月，沛公兵遂先诸侯至霸上。秦王子婴素车白马，系颈以组，封皇帝玺符节，降轵道旁。诸将或言诛秦王。沛公曰：“始怀王遣我，固以能宽容；且人已服降，又杀之，不祥。”乃以秦王属吏，遂西入咸阳。欲止宫休舍，樊哙、张良谏，乃封秦重宝财物府库，还军霸上。召诸县父老豪桀曰：“父老苦秦苛法久矣诽谤者族偶语者弃巿吾与诸侯约先入关者王之吾当王关中。与父老约，法三章耳：杀人者死，伤人及盗抵罪。余悉除去秦法。诸吏人皆案堵如故。凡吾所以来，为父老除害，非有所侵暴，无恐！且吾所以还军霸上，待诸侯至而定约束耳。”乃使人与秦吏行县乡邑，告谕之。秦人大喜，争持牛羊酒食献飨军士。沛公又让不受，曰：“仓粟多，非乏，不欲费人。”人又益喜，唯恐沛公不为秦王。

    或说沛公曰：“秦富十倍天下，地形强。今闻章邯降项羽，项羽乃号为雍王，王关中。今则来，沛公恐不得有此。可急使兵守函谷关，无内诸侯军，稍徵关中兵以自益，距之。”沛公然其计，从之。十一月中，项羽果率诸侯兵西，欲入关，关门闭。闻沛公已定关中，大怒，使黥布等攻破函谷关。十二月中，遂至戏。沛公左司马曹无伤闻项王怒，欲攻沛公，使人言项羽曰：“沛公欲王关中，令子婴为相，珍宝尽有之。”欲以求封。亚父劝项羽击沛公。方飨士，旦日合战。是时项羽兵四十万，号百万。沛公兵十万，号二十万，力不敌。会项伯欲活张良，夜往见良，因以文谕项羽，项羽乃止。沛公从百馀骑，驱之鸿门，见谢项羽。项羽曰：“此沛公左司马曹无伤言之。不然，籍何以生此！”沛公以樊哙、张良故，得解归。归，立诛曹无伤。

    Owning a smartphone may not be as smart as you think. It may let you surf the Internet, listen to music and snap photos wherever you are…but it also turns you into a workaholic, it seems.

    A study suggests that, by giving you access to emails at all times, the all-singing, all-dancing mobile phone adds as much as two hours to your working day. Researchers found that Britons work an additional 460 hours a year on average as they are able to respond to emails on their mobiles.

    The study by technology retailer Pixmania reveals the average UK working day is between 9 and 10 hours, but a further two hours is spent responding to or sending work emails, or making work calls. More than 90 percent of office workers have email-enabled phones, with a third accessing them more than 20 times a day. Almost one in ten admits spending up to three hours outside their normal working day checking work emails. Some workers confess(承认) they are on call almost 24 hours a day, with nine out of ten saying they make work emails and calls outside their normal working hours. The average time for first checking emails is between 6 a.m. and 7 a.m., with more than a third checking their first emails in this period, and a quarter checking them between 11 p.m. and midnight.

    Ghadi Hobeika, marketing director of Pixmania, said, “The ability to access literally millions of apps, keep in contact via social networks and take photos and video as well as text and call has made smartphones invaluable for many people. However, there are drawbacks. Many companies expect their employees to be on call 24 hours a day, seven days a week, and smartphones mean that people literally cannot get away from work. The more constantly in contact we become , the more is expected of us in a work capacity(容量).”
