【正确答案】 A

【答案解析】[分析] 本题为动词辨析。rise升起，上升，只能作不及物动词用。其次，句中“the number of+可数名词”表示“数目或整体”，谓语动词用单数，所以A是正确答案。例如：The sun rises in the East. The smoke from our fire rose straight up in the still air。 raise举起；饲养，养育，一般作及物动词用。例如： The container which is full of water is so heavy that nobody can raise it to the surface of the water。Now many people like rinsing flowers on the top, of buildings。arouse引起，唤起。lift举起，升起，抬起。
