句型结构分析
NPR's Jason Beaubien reports the governor of Jalisco state in Mexico is now calling on bar owners to install metal detectors at their doors.

优质解答

NPR's Jason Beaubien作主语 report为谓语 后面接一个宾语从句
从句中主语是the governor of Jalisco state in Mexico 谓语是is now calling on 宾语是bar owners 后面的to install等做不定式 表示目的,也就是call on sb to do sth结构
