不好意思,刚刚没有看清
还是用turning 好些,turned是过去分词,表被动我在想turn前是不是省略了主语，如果是连词的话前后时态应该一致。Waiting for her husband to come back,the middle-aged woman stood there still as though _____to a stone.原题是这个。。A.turningB.turnedC.to turn D.turns是这样的，可以省略主语，这时候就只能用动词的ing形式了，如果不省略的话，那就是 He stood there still as if he had turned into a stone.这时候得用虚拟语气，时态往前面推一级。
