我觉得应该是B 拎出这部分主干 the Virtual Leonardo Project encourages visitors to “touch” each exhibit, which thereby activates the animated functions of the piece. B. exhibit, in turn an activation of D. exhibit and thereby activate 如果是D,那么主语是谁呢,是Museum的话,activates应该是单数。 如果是visitors的话,就变成Museum encourages visitors to “touch” each exhibit and thereby activate。 这样逻辑上明显不对,博物馆可以鼓励游客去触摸,可怎么能“因尔”鼓励游客去active呢,这样逻辑不通阿。 相反,B里面的an activation of是指代前面visitors触摸展品的这件事,同位语结构,表示是visitors的这个行为active了functions. |
