A number of intriguing studies published in the past 18 months, including Smathers’, have raised that possibility — an issue that has special resonance now, with this weekend’s start of the 2009 Tour de France.

不是说一个句子只有一个谓语吗?怎么这个句子这么多谓语,像published ,have raised,start.

这个句子的主语A number of intriguing studies, 从pubulished到Smathers是定语，
谓语 have raised
宾语 that possibility, 破折号之后是宾语从句
