■ compared

是个动词过去分词，本来应该同句中的一个名词成分相联系，但是往往在句中处于“游离”地位，意义相当于副词。

• If you are an actual smoker or have been one, you run four times the risk of developing the condition compared to(= in comparison with) non-smokers.你如果现在是个抽烟者，或者曾经是抽烟者，那么，你患上这个病的风险就比不抽烟者大四倍。

类似这样的，还有 effective，based (on)，relative (to) 等形容词。
