A．cut B．to cut C．cutting D．cutted
Your hair is too long. You’d better have it ________.
A．cut B．to cut C．cutting D．cutted
A 点拨：本题用固定短语法解题。句意：你的头发太长了，你最好请人理一理。“ have ＋ sth. 
(宾语)＋ 过去分词(宾语补足语)”意为“让 / 叫 / 使 / 请别人做某事”。宾语sth.后面用过去分词作宾语补足语，说明sth.与过去分词表示的动作之间是被动关系。根据句意，请人理发应是have hair cut 。cut的过去式、过去分词与动词原形一致。故选A。
