首先虚拟语气是用在句子中。当suggest后加句子的时候，就用虚拟语气；但你说的suggest doing是非谓语动词的语法，有一些动词后面要加ing.比如：enjoy doing, appreciate doing, consider doing等等。
显然不是，无论什么词,后面可能发生虚拟语气的一定都是加(should) +do
我觉得是啊,我记得老师说过suggest及其变式都是虚拟,suggest是建议,建议就是没发生嘛!应该是虚拟语气
不是啊,suggest做建议,提议解时,[+v-ing][+(that)][+wh-] I suggest our going to the park on Sunday. 我建议我们星期天去公园. The dentist suggested that she (should) come another day. 牙医建议她改天再来。
