His uncle made a film _______ his story in his childhood.

A．based on

B．was based on

C．basing on

D．to base on

答案

A

解析

试题分析：考查形容词短语做定语修饰名词。本题中的固定搭配be based on…以…为基础；本句中的形容词短语based on…是修饰名词a film。句意：他的叔叔拍了一部以他童年的故事为基础的电影。这里的based on…="which" is based on…。故A正确。
点评：形容词做定语的时候可以和定语从句互换使用，要注意一些固定搭配的辨析如base的词组base A on B 把A放在B的基础之上，可以转换为A be based on B 形成这样的一个形容词的短语。
