【正确答案】 C

【答案解析】[解析] 句意：下了两个礼拜的雨，结果我们的假期全泡汤了。本题考查的是现在分词的用法。句中是现在分词短语作结果状语，completely ruining our holiday是一个现在分词短语作结果状语，ruin的逻辑主语是前一句话。也就是说It has been raining for two weeks, completely ruining our holiday.=It has been raining for two weeks and it has completely ruined our holiday.故C正确。 现在分词作结果状语。 e.g.：(1)Their car was caught in a traffic jam, thus causing the delay.他们的车遇上交通阻塞，因而耽误了。 (2)Her husband died ten years ago, leaving three children for her to look after.她丈夫十年前去世了，留下了三个需要她照顾的孩子。
