It's just been three months after the first bike-sharing company arrived in Singapore, but reports of abuse and vandalism（故意破坏）of shared bikes in the city keep appearing on social media.

    The majority of these shared bikes are stationless, which means they don't need to be stopped at a designated（指定的）spot. They lock themselves after your ride is over, and you're meant to just leave the bike at the side of a road.

    But users have been chaining up bicycles outside their apartments, preventing others from using them. Some people bring them up to their apartment floors, so they can't be found easily by other users. Some people have removed the bikes' number plates or codes, and some even have painted over the bikes to claim the bikes for themselves. Most of the abused bikes belong to either Singapore-based oBike, or ofo, a bike-sharing giant based in China.

    ofo has encouraged Singaporean users to report issues. oBike said that the number of bicycles that were damaged made up less than one percent of its fleet. The company said in February that it planned to bring in “tens of thousands” of bikes by mid-2017. The company has yet to ban anyone from its service, but said that it would take appropriate action – including making reports to the police.

    oBike also introduced a shortcoming system, similar to that of its competitor, China-based Mobike. Users start with 100 points, which get taken away for errant（出格的）behaviour such as forgetting to lock the bike, or parking at non-designated areas. Users are banned from using oBike when their scores reach zero. oBike has an eight-man operation team that can remove bicycles parked casually.

    When approached for comment, Mobike said, “In China, just as in Singapore, there are always a tiny minority of people who abuse the bikes, so we designed our system to prevent this type of abuse.”

    现在他们真是惊慌到了极点。从日记中，人们可以觉察到斯科特如何尽量掩饰着自己的恐惧，但从强制的镇静中还是一再迸发出绝望的厉叫：“再这样下去，是不行了”，或者“上帝保佑呀!我们再也忍受不住这种劳累了”，或者“我们的戏将要悲惨地结束”。最后，终于出现了可怕的自白：“惟愿上帝保佑我们吧!我们现在已很难期望人的帮助了。”不过，他们还是拖着疲惫的身子，咬紧牙关，绝望地继续向前走呀，走呀。奥茨越来越走不动了，越来越成为朋友们的负担，而不再是什么帮手。一天中午，气温达到零下40摄氏度，他们不得不放慢走路的速度，不幸的奥茨不仅感觉到，而且心里也明白，这样下去，他会给朋友们带来厄运，于是作好了最后的准备。他向负责科学研究的威尔逊要了十片吗啡，以便在必要时加快结束自己。他们陪着这个病人又艰难地走了一天路程。然后这个不幸的人自己要求他们将他留在睡袋里，把自己的命运和他们的命运分开来。但他们坚决拒绝了这个主意，尽管他们都清楚，这样做无疑会减轻大家的负担。于是病人只好用冻伤了的双腿踉踉跄跄地又走了若干公里，一直走到夜宿的营地。他和他们一起睡到第二天早晨。清早起来，他们朝外一看，外面是狂吼怒号的暴风雪。

    奥茨突然站起身来，对朋友们说：“我要到外边去走走，可能要多呆一些时候。”其余的人不禁战栗起来。谁都知道，在这种天气下到外面去走一圈意味着什么。但是谁也不敢说一句阻拦他的话，也没有一个人敢伸出手去向他握别。他们大家只是怀着敬畏的心情感觉到：劳伦斯•奥茨这个英国皇家禁卫军的骑兵上尉正像一个英雄似的向死神走去。

    现在只有三个疲惫、羸弱的人吃力地拖着自己的脚步，穿过那茫茫无际、像铁一般坚硬的冰雪荒原。他们疲倦已极，已不再抱任何希望，只是靠着迷迷糊糊的直觉支撑着身体，迈着蹒跚的步履。天气变得愈来愈可怕，每到一个贮藏点，迎接他们的是新的绝望，好像故意捉弄他们似的，只留下极少的煤油，即热能。3月21日，他们离下一个贮藏点只有20公里了。但暴风雪刮得异常凶猛，好像要人的性命似的，使他们无法离开帐篷。每天晚上他们都希望第二天能到达目的地，可是到了第二天，除了吃掉一天的口粮外，只能把希望寄托在第二个明天。他们的燃料已经告罄，而温度计却指在零下40摄氏度。任何希望都破灭了。他们现在只能在两种死法中间进行选择：是饿死还是冻死。四周是白茫茫的原始世界，三个人在小小的帐篷里同注定的死亡进行了八天的斗争。3月29日，他们知道再也不会有任何奇迹能拯救他们了，于是决定不再迈步向厄运走去，而是骄傲地在帐篷里等待死神的来临，不管还要忍受怎样的痛苦。他们爬进各自的睡袋，却始终没有向世界哀叹过一声自己最后遭遇到的种种苦难。
