He helped popularize the idea that some diseases not【B4】______thought to have a bacterial cause were actually infections, which aroused much controversy when it was first suggested.
    【B5】______he, however, might tremble at the【B6】______of what he is about to do.

选项 A、assessing
B、supervising
C、administering
D、valuing

答案D

解析 考查动词辨析。联系上文,“对西方的学术方面和文化方面作出了巨大贡献”应该与“高度重视教育”紧密相关。因此答案应该选D.valuing。value本义为“评价”,此处意为“重视,看重”。assess“评估,评价”,没有“重视”的意思。supervise“监督”,administer“管理,掌管”,均不符合题意。
