A. best; read

B. well; read

C. better; read

D. more; should read

答案：

A. best; read

B. well; read

(答案→)C. better; read

D. more; should read

解析：考查习惯搭配，比较级和虚拟语气的用法。句意：--你读过这本书吗？--是，但是那本更值得读，我建议你如果有时间读一读。be well worth 是习惯搭配，这里面是比较,表示that book更加好, 所以better worth reading.，第二空用虚拟语气，主句的谓语是suggest的时候，谓语用should do，should可以省略，选C。
