one event that occured in the past is being compared to all the events that have occured till now.
So the past event is denoted with a simple past . This past event (ie. one specific event that has occured in the past- that event that got 12 million immigrants) is compared to all the events until now( ie. all the events in the past and all the events till now. so what tense is needed for an event has started in the past and is applicable even today? That is the reason why we denote all the other events in the present perfect!)
so, the present perfect is appropriate here, if the sentence wishes to (1) imply that there could reasonably be more waves of migration, or (2) emphasize the continuing impact that those waves have on today's world. at least the second of these is definitely happening in the sentence at hand. 作者: huosijie 时间: 2014-2-20 04:54
