题目

麻烦翻译这段英语,谢谢了
To keep leaves and other debris from entering a rooftop rainwater harvesting system, the gutters should have continuous leaf screens made out of onequarter-inch wire mesh screen in a metal frame or an equally efficient product covering the entire length of gutter. Installing leaf screens will help reduce a rainwater harvesting system’s maintenance, eliminate flammable material from the roof area,reduce mosquito breeding habitat,and eliminate the need for
frequent and potentially hazardous use of a ladder to clean the gutters.

答案

为了防治落叶和其它杂物进入屋顶的雨水收集系统,排水沟应当配有连续的由金属框架罩以4分之一英寸网眼大小的网片制成的遮叶屏,或者配备遮盖排水沟全长的遮盖物也能达到同样的效果.装有遮叶屏可以减少屋顶雨水收集系统的维修,减少屋顶的可燃物堆积,降低蚊虫滋生的条件,也能减少时常使用梯子清洁排水沟可能发生的事故风险.
希望对您有帮助.
