高考英语非谓语动词11个重要考点(10)

　　考查“(be +) 过去分词+介词”结构
　　有一类“be+过去分词+介词”结构，如be interested in, be worried about, be lost in, be dressed in 等，也往往是命题的热点。如：
　　1. _____ in the mountains for a week, the two students were finally saved by the local police.
　　A. Having lost B. Lost C. Being lost D. Losing
　　分析：答案选 B。因表示“迷路于”是lose oneself in，题中没有oneself, 所以the two students与lose是被动关系，应该用过去分词作状语。
　　2. _____ in a white uniform, he looks more like a cook than a doctor.
　　A. Dressed B. To dress C. Dressing D. Having dressed
　　分析：答案选 A。由dress的宾语一定是人或oneself可知，dress与he是动宾关系，即he与dress是被动关系，要用过去分词作状语，Dressed in …=As he is dressed in …
