1. On the important feast day, people eat food in the shape of skulls and cakes with “bones” on them. (P2)
此结构为“with + 宾语（bones）+ 补语（on them)”，on them是介词短语在with 复合结构中作补语。除此以外作补语的还有形容词、副词、现在分词、过去分词和不定式等。如：
With the boy helping us, we had no difficulty finding the way out. 有了这个男孩的帮助，我们毫不费力的找到了出路。
With many things to deal with, I have to stay up late tonight. 有许多事情要处理，今晚，我只好熬夜了。
