答案

可以的.
现在分词=which+主动语态,过去分词=which+被动语态
例：
a package of materials,【circulated】 to all schools……
= a package of materials,【which was circulated】 to all schools……
a second pack,【supporting】 schools against bullying,【produced】 the following year
= a second pack,【which supported】 schools against bullying,【which was produced】 the following year
