中译英,在过去一年的检修统计中,我们发现由黑心钉导致轮胎破损的公共自行车占需要维修车辆总数的20%,尤其是在城郊问题补充

In the maintenance statistics made in the past year,we found that the public bikes whose tires were damaged by the nails put on the roads on purpose reached 20% of all the bikes needing repairing.Things were worse in the suburbs.
“黑心钉”我采取的意译.意为：“被故意放在路上的钉”
欢迎指正,探讨,共同进步!
