When________there, the postman found the door locked and then stopped ______the letter under it.

A．reaching;to stick

B．reached;to stick

C．reaching;sticking

D．reached;sticking

答案

A

解析

第一个空考查非谓语动词，the postman与reach之间为主动关系因此用现在分词，第二个空考查stop doing 停止作某事与 stop to do 停下来去做，这两个短语的区别。根据语境邮递员发现门锁着然后就把信塞在了门下面。所以选to stick 。
