问题 单项选择题

But in our enthusiasm to discover our heritage, we are ruining the very scenery we go to enjoy, damaging natural habitats, ______ down footpaths, disturbing wildlife, polluting the air and dropping litter.

A. wearing
B. treading

C. falling

D. cutting

答案

参考答案:A

解析: 原句中的mining the very scenery we go to enjoy, damaging natural habitats,______ down footpaths, disturbing wildlife, polluting the air和dropping litter均为并列关系,从意思上看,空白处的词应和ruin,damage,disturb,pollute呈同义关系,即应当是表示“破坏”类的词,故用wear。wear down是固定词组,意思为“磨损”,如:The heels of my shoes are wearing down.(我的鞋跟磨损了。)其他三个动词此处与down搭配,都在逻辑语义上不通。
