infrastructure中等

The huge improvements in Italy’s obsolete infrastructure partly explained the disruption, said Ferrovie.

意大利国家铁路集团表示，对意大利陈旧基础设施进行的大规模改进在一定程度上解释了运行中断的原因。

Ferrovie will invest a total of €124bn in infrastructure over the next 10 years.

意大利国家铁路集团将在未来10年内总共投资1240亿欧元用于基础设施建设。

Christopher Kettle, Biodiversity International’s director for forest genetic resources and restoration in Rome, says that the need for infrastructure — things such as mechanisms for collecting and storing seeds, and nurseries to raise seedlings — might be most desperate here because many trees are ‘masting’ species, which don’t produce seeds every year.

国际生物多样性中心驻罗马的森林遗传资源与恢复主任克里斯托弗·凯特尔表示，这里对基础设施——诸如收集和储存种子的机制以及培育幼苗的苗圃——的需求可能最为迫切，因为许多树木属于“大年结实”物种，并非每年都结种子。

Roads, trails, restrooms, visitor centers and other infrastructure are crumbling.

道路、步道、洗手间、游客中心及其他基础设施正在破败。

Campgrounds are a tiny portion of the overall infrastructure backlog, and businesses in the parks hand over, on average, only about 5% of their revenues to the National Park Service.

露营地在全部基础设施积压项目中只占极小一部分，而且公园内的商家平均只把约5%的收入上缴给国家公园管理局。

Poorly maintained infrastructure.

基础设施维护不善。
