高中语法填空题，第一个空填collect的什么形式，第二个空填什么词，为何？
The project is being funded from fines from traffic tickets in the town, which law have to be reinvested in road safety.
The project is being funded from fines from traffic tickets in the town, which law haveto be reinvested in road safety.
【说明】高考考试考试试题的“语法填空” 新题型，是由原来的“四选一”变来。给出一个语篇，10个空，大多数题目是“词形变化”，其余题目是“自由填空”。网友的例子便是。
第一空：是词形变化。把collect 变成 collected。它跟fines 是被动关系：罚款被收取。如此，过去分词短语collected from traffic tickets in the town， 作fines 的定语。
第二空：是自由填空。which 指代fines，文中出现law，句意一定与法律有关，要依法办事。意思是“这类罚款依据法律怎么样”，这里需要一个表示“依据”的介词by。
完成后的句子是：
The project is being funded from fines collected from traffic tickets in the town, which by law has to be reinvested in road safety.
【翻译】该项目的资金来自城镇交通罚单中收取的罚款，依据法律，这类罚款需要再投资于道路安全建设。
