Venice is a fragile jewel faced with rising sea levels from climate change and mass tourism. Of the estimated 30 million visitors a year, around two thirds are day trippers, placing sites under huge strain. 

威尼斯就像一颗脆弱的宝石，一方面面临着气候变化导致海平面上升的威胁，同时也需要应对大量游客带来的挑战。每年约有3000万名游客访问威尼斯，约三分之二是当天往返的一日游游客，这给威尼斯带来了游客大批涌入的巨大压力。

Now they'll have to pay €5 to enter the city in a trial scheme in place on specific days over the next few months. The aim, say the authorities, is to discourage crowds descending at certain times, adding that the plan, the first such one in the world, could be extended in duration and price. Critics say the ticket is a minimal cost that will not address Venice's fundamental problems. 

现在一项试行方案规定，在未来几个月的特定旅游高峰日，一日游游客们必须支付5欧元才能进城观光。威尼斯官方表示，这样做的目的是阻止人群在特定日子大批涌入威尼斯，并补充说，作为世界上首个推行 “进城费” 的方案，试行收费的时间可能会延长，价格也可能会上调。反对 “进城费” 方案的人说，收费很低，无法解决威尼斯面临的根本问题。 

Other cities facing similar overtourism challenges will be watching closely to see if it works. 

其它面临类似客流量过大问题的城市将密切关注该试行方案，看它是否奏效。
