leave用法I was told that it was a very serious disease.
If left___properly,the patient might lose his ability to walk about in just a year or so答A.untreated B.being untreated C.untreat
答案
选A是正确的,但楼上的解释有些问题.应该是leave+ 宾语+形容词 / 分词 / 不定式等,表示使(宾语)保持某种状态.If (it is) left untreated 在这里省略了 it is ,其实它是一个被动语态,还原回去是left it untreated (it指the legs ).这句话意为“如果(腿)继续不被治疗,这个病人也许将在近一年或更长时间内失去行走能力.”.
