His pale face suggested that he ill and his teacher suggested that he to the hospital at once.
A. be; send
B. were; should send
C. was ; be sent
D. were ; be sent

A. be; sendB. were; should send(答案→)C. was ; be sentD. were ; be sent解析：考察suggest用法。Suggest表示建议的时候，后面的句子使用虚拟语气：should do构成，should可以省略；当suggest表示暗示，说明的时候，后面使用陈述语气。第一空前的suggest意为暗示，说明，所以使用陈述语气；第二空前的suggest意为建议，后面使用虚拟语气。结合句意可知C正确。句意：他苍白的脸色说明他病了。他的老师建议他立刻去医院。

就是这个解释
