问题 Steamboats began to sail up and down the Mississippi River at the beginning of the 19th century, which contributed a lot the areas along the river.

选项 A、to develop
B、to being developed
C、to be developed
D、to developing

答案 D

解析 本题考查动词与介词搭配。本句是非限定性定语从句,which指代前句,从句中contribute与介词to搭配,后接动名词,而且沿河地区与发展是动宾关系,所以应选D.to developing。contributed a lot to意思是:对…做出很多贡献,极大地有助于…。这句话的意思是:十九世纪初期,汽轮开始在密西西比河来来往往地航行,这大大地促进了沿河地区的开发。
