选项
A、invented
B、discovered
C、investigated
D、designed
答案
D
解析
词义搭配。be designed to do sth.(=be made or planned for a particular purpose or use)是一个习语,意为(=be made or planned for a particular purpose or use)为某目的和用途而研制或谋划。例如:The route is designed to relieve traffic congestion.(这条路是为缓解交通拥挤而开辟的)。 invent vt.发明,discover vt.发现,investigate vt.调查研究,均不合题意,因为天花疫苗不是"发明的","发现的","调查研究的",而是为一特定目的或用途"研制出来的",故应选designed。
