身体的同盟者机体试图恢复健康

医师加入到对抗疾病的战争中
He would read the signs to decipher the underlying process;

他观察身体的信号来破译潜在的运行规律
would take a case history; would practice close observation,

参考病例仔细诊断
taking the pulse,

诊脉
listening to the body; and would examine the urine,

听音检尿
its color, its density.

包括尿的颜色及密度

他会闻尿的味道并尝一下
and see whether it contained blood or was frothy,

了解其中是否含血或是起泡
