问题补充：

Will was lying on the grass, the sky thick with stars.

A. his eyes fixing on

B. fixed his eyes on

C. his eyes were fixed on

D. his eyes fixed on

答案：

A. his eyes fixing on

B. fixed his eyes on

C. his eyes were fixed on

(答案→)D. his eyes fixed on

解析：考查独立主格结构，分析句子成分，前面的是个简单句，两句话之间没有连词，所以逗号后面不是简单句，而是独立主格结构，逻辑主语+非谓语动词，his eyes和fix是被动关系，用过去分词，句意：Will正躺在草地上，眼睛注视着星星密布的天空。选D。
