A. is

B. are

C. am

D. be

答案：

A. is

(答案→)B. are

C. am

D. be

解析：句意：不仅我，而且Jane和Mary都厌倦了一次又一次的考试。Not only…but also在连接两个主语时，谓语动词要与最近的主语保持一致，即就近原则，即：谓语与靠近的名词、代词（有时不一定是主语）在“人称、数”上一致。这些词组有not only...but also..., either...or..., neither...nor...等。there be ……句型，Neither……nor…… ，Either……or……， Not……but…… ，Whether……or…… Not only……but also……。由结构可知选B。
