  A rise in the concentration of health-threatening dust particles causing pollution in many Italian cities has prompted the government to act. A host of new measures have been put on the table for the whole country.意大利许多城市面临威胁性健康粉尘颗粒浓度上升的污染,促使政府采取行动。全国范围一系列新的措施已经摆上桌子。They include encouraging local councils to replace ageing buses with more environmentally friendly ones and incentives for drivers to trade in their cars for less polluting vehicles.It all comes at a cost.其中包括鼓励地方委员会使用更为环保的公共汽车替换过时的,并鼓励司机交易低污染的汽车。这都需要一定的代价。On top of these measures there will also be discounts on public transport, bus and city metros. These discounts are supported by a fund of 12 million euros which will be made available by my ministry from the last day of the year.除了这些措施以外,还包括在公共交通、公交和城市地铁上打折扣。这些优惠由1200万欧元基金资助,从今年的最后一天开始可以实行。The government’s move follows this week’s introduction of traffic and speed restrictions in Rome, Milan and several other cities. But the action failed to curb pollution levels.政府举措紧跟着本周罗马、米兰和其他几个城市实行交通和速度限制,但行动未能遏制污染水平。Rockets, firecrackers and flares have been banned in public spaces in Milan, Bologna and Turin.米兰、洛尼亚和都灵在公共场所禁止燃放烟花、鞭炮和照明弹。But environment activists said the measures do not go far enough.但环保人士表示,仅靠这些措施还远远不够。译文属。 /201512/419217
