So sleepy that he could hardly keep his eyes.A. John was; openB. was John; openC. John was

问题补充：

So sleepy that he could hardly keep his eyes.

A. John was; open

B. was John; open

C. John was; opened

D. was John; opened

答案：

A. John was; open

(答案→)B. was John; open

C. John was; opened

D. was John; opened

解析：考查倒转句和形容词用法。当so+形容词/副词放在句首的时候，后面的句子使用部分倒装的形式。第二空的open是形容词在句中作为宾语补足语。句意：他感觉到如此的困以至于他很难睁开眼睛。故B正确。
