—When Tom________，please let me know.—Mary said when Tom________，just tell her about it. A

—When Tom________，please let me know.—Mary said when Tom________，just tell her about it. A．comes；comes B．came；came C．comes；came D．comes；coming

Answer 1

C

句意：当Tom来的时候，请告诉我。When引导的时间状从用一般现在时表将来；Mary said when Tom________，just tell her about it是转述别人的话，因为主句用的是一般过去时态，said后面when引导的宾从也用过去时态的某种形式。所以选C。 。
