问题 Although the study of genetics is an entirely new field, it______mankind for many years.

选项 A、has combined
B、has interested in
C、has involved
D、has fascinated

答案D

解析动词词义辨析。combine“使结合；联合”。interested in“感兴趣”。involve“包括其中；被卷入；涉及”。fascinate“沉迷于”。根据句意排除选项A。interested in的主语应为人而不是物，可排除。根据句意判断基因研究让人类着迷而不是仅仅涉入该领域，故答案为D。
