As soon as the program came out than 30 years ago

As soon as the program came out than 30 years ago,Western children became interested in reading this story because the clever Monkey King keeps fighting to help the weak and never gives up.分析一下句子，顺便说下这句话的意思。

一旦程序出来比30年前,西方儿童阅读这个故事感兴趣,因为聪明的孙悟空一直努力帮助弱者,永不放弃。

在这里became是过去式，interested不是过去式 而是形容词形式，become interested in类似于be interested in，表示”对……变得感兴趣”；至于become用过去式，是因为句子中说30多年前，是过去的时间。 希望能帮到你。
