问题 ______in the cultivation of a forest, trees need more careful planning than any other crop does.

选项 A、Because the time and area involved
B、For the time and area involving
C、Because of the time and area involved
D、As a cause of the time and area involved

答案 C

解析 句意:因为森林养育需要耗费时间和土地,所以树木种植需要更加精心的规划。由结构和句意可知。前半句可作为主句的原因状语,即可排除A、D项。又因为时间和土地是被消耗的关系,从句中动词应为被动时态,故选C。
