||1: He had thought about this for years, wondering how he might visualise time. ||2: He did not mean the time of clocks or calendars or hour-glasses; those were merely instruments of convenience for fixing points at which to have coffee, or feed the cat. ||3: That was time you could even reverse, by winding back the clock or tipping the hourglass over. ||4: He meant the irreversible continuum of time that flowed through him, the pulse of his life approaching his death within the vastness of infinity. ||5: For some years early in the 1960s he had played around with dabs and zigzags of monochrome paint on canvases which he called “Chronomes”, but he concluded that time was more orderly than that. ||6: By painting numbers in careful succession from one to infinity, or as near to it as he was destined to get, he would make a work of art that tracked as well as anything the movement of time in a life, and life in time.

||1:关于怎样才能表达出时间的印象，他已经深思熟很多年。||2:他想要的表达，不是时钟、日历、时漏这些仪器，这些仪器的用处是提醒人们什么时候去喝咖啡，什么时间去喂小猫咪。||3:这样子的时间甚至都可以往回拨，钟表的指针可以回调，时漏可以颠倒。||4:他想要表达出来的，是穿过他自己的时间，那是不可逆转的连续的时间，是在无限的广漠之中他生命的脉搏走向了死亡。||5:在二十世纪六十年代早期几年里，他曾试着在用一种颜色在画布上点点，或是画之字，这种画他称之为“染色体”，但是最后他得出了这样的结论，即时间比它们都有序。||6:所以他才想到用这样的方法来画画，在画布上写下数字，从一到无限，至少，到他有生之年能够到达的那个数字，这样，他能创作出的艺术品，才是对时间在生命之中的运动，或对生命在时间中的运动所做的纪录。

Today the government crows about the failings of past administrations while presiding over an intensification of the same problems. At current rates, real earnings will have shrunk by ￡6,660 ($10,250) over the 2010-15 parliament.|| The hourglass shape of the labour market has become more pronounced: research by the Trades Union Congress shows that four in five net jobs created up to December 2012 were in low-wage sectors.|| As before, the squeezed middle is turning to credit cards to compensate; in the first quarter of 2013 the savings ratio fell to 4.2%, its lowest since 2009.

1:如今英国政府一边在“哭诉”曾经管理层的失败，一边又在同样的问题上栽了更大的跟头。||2:就目前利率来看，在2010至2015年议会期间，公民真实收入将缩减至6,660欧元（折合美元10,250元）。||3:劳务市场需求沙漏化更加明显：英国总工会（Trades Union Congress）的一项研究表明，至2012年11月，由低工资部门提供的净就业机会占总数的五分之四，而那些被限制的中等水平求职者只好利用信用卡来支付各项费用。||4:2013年第一季度英国储蓄率跌至4.2%，是自2009年以来的最低水平。
