近来，不少男女老少沉迷于一种叫“偷菜”的游戏，据玩家们的心得，这玩意儿“妙”就。妙，一个“偷”字，“偷”得好才算玩得好，敢于“偷”才能赢得大。只有千方百计去“偷菜”才能迅速发家致富，而老老实实“种菜”的，常常空忙一场。

又如前段热播的电视剧《蜗居》，片中有位叫宋思明的“公仆”，以其见不得光的精、明智巧，“偷”得巨额国家资财，还有位叫海藻的女子，不惜以权色交易“偷”得荣华富贵。对他们的“偷”，声讨者有之，但也不乏羡者、力挺者。

游戏偷太真，但虚构情节中隐藏的现实逻辑却不能不认真。“偷”的背后意味深长，它不只是一种玩法，更象征一种途径：为了利益、为了成功、可以急功近利、不择手段，不管道义而达到目的。

面对“敢偷才会赢”的成功观，不妨听听哲学家约翰?罗斯金的忠告：“人劳碌一生，其最高奖赏不在于他从中获得了什么，而在于他借此成为了一个什么样的人。”在满眼诱惑面前，在追求成功的躁动之中，我们需要扪心自问：“偷”还是“不偷”？这是个关系生命价值的抉择。

Passage Two

 Some futurologists have assumed that the vast upsurge(剧增)of women in the workforce may portend a rejection of marriage, Many women, according to this hypothesis, would rather work than marry． The converse（反面）of this concern is that the prospects of becoming a multi-paycheck household could encourage marriage．In the past, only the earnings and financial prospects of the man counted in the marriage decision． Now, however, the earning ability of a woman can make her more attractive as a marriage partner． Data show that economic downturns tend to put off marriage because the parties cannot afford to estabZish a family or are concerned about rainy days ahead． As the economy comes to iife, the number of marriages also rises．

The increase in divorce rates follows, with the increase in women working outside the home． Yet, it may be wrong to jump to any simple cause-and-effect conclusions．The impactof a wife's work on divorce is no less cloudy than its impact on marriage decisions．The realization that she can be a good provider may increase the chances that a workir．g wife will choose divorce over an unsatisfactory marriage．But the reverse is equally plausible(似是而非的)． Tensions grounded in financial problems often play a key role in ending a marriage． By raising a family's standard of living, a working wife may strengthen her family's financia! and emotional stability．

Psychologicai factors also should be considered． For example, a wife blockecZ from a career outside the home may feel caged in the house．She may view her only choice as seeking a divorce． On the other hand, if she can find fulfillment through work outside the home, work and marriage can go together to create a stronger and more stable union．

 It generated(生成) one of the most destructive Pacific-wide tsunami（海啸）． Near the generating area, both the earthquake and the tsunami were very much destructive, particularly in the coastal area from Concepcion to the south end of Isla Chiloe．The largest tsunami damage occurred at Isla Chiloe-the coastal area closest to the epicenter(震中)．Huge tsuna- mi waves measuring as high as 25 meters arrived within l0 to 15 minutes after the earthquake, killing at least two hundred people, sinking all the boats, and flooding half a kilometer inland．
