The safety precautions taken include a blood alcohol reading and a Climb Simulator,which shows climbers the climbing conditions that might be experienced on the Bridge.
这里面的taken是过去分词作后置定语,表示被动含义吗? 但是为什么不可以填should be taken ?
The safety precautions taken(主语)// include(谓语)// a blood alcohol reading and a Climb Simulator(宾语),//(非限制性从句)which shows climbers the climbing conditions that might be experienced on the Bridge.
taken 过去分词作后置定语,include为谓语动词.
主句语法结构分析如下
主语:the safety precautions
修饰主语后置定语:taken
谓语:include
宾语:a blood alcohol reading and a Climb Simulator
备注:主语为复数precautions;谓语动词也是复数include,因此不能把taken改为should be taken
