15. As Polly was riding on the train, she sensed that she was by a tall man in a dark coat.

A. being stared

B. being watched

C. being attached

D. glanced

答案：

A. being stared

(答案→)B. being watched

C. being attached

D. glanced

解析：考查非谓语动词。She和watch是动宾关系，即“她被注视着”，故用过去分词；stare不及物，应该用stare at。她感觉到有人正在注视着她，应该用进行时。故选B。
