"I would not be,at this point,if they had another way of transportation,suggesting they ride the subway."
“目前,如果他们有其它的交通方式可以选择的话,我就不会推荐他们乘坐地铁.”
分析：if they had another way of transportation是虚拟语气,“如果他们有其它的交通方式可以选择”,I would not be suggesting they ride the subway也是虚拟语气,“我就不会推荐他们乘坐地铁.”
to suggest somebody do something：注意此处的do 要用动词原形.
