这道题是挑错题，答案是extending应改为extended。我认为 he got his visa extending是一个完整的句子。只能有一个谓语动词，got就是。所以extending以动名词形式存在是对的。可是答案说，get sth done是固定用法，那么固定用法就可以例外了是吗？
那可太难界定了。一个动词必然有发出者和承受者，那这动词对于发出者是被动的。对于承受者是主动的，那我该怎么办啊。我从网上查到的是这样的：语态是动词的一种形式，它表示主语和谓语的关系。语态有两种：主动语态和被动语态。如果主语是动作的执行者，或者是说动作是由主语完成的，要用主动语态；如果主语是动作的承受者，或者是说动作不是由主语而是由其他人完成的，则用被动语态。

按照克丽泰的说法，那这个简单句里就有2个动词了。一个是get一个是和visa构成谓语关系的extend。

这个是被动语态 get sth done 是把他的visa卡延期了
这里是visa和延期的主谓关系不是 he 和 extend
这个句子的翻译是，这个男孩不用第二天离开了，因为他把他的visa卡延期了。
就相当于He got his cloth washed. 是他把他的衣服洗了。这里是衣服和洗的主谓关系虽然主语是他但被洗的是衣服而不是他同样在这个句子中 he got his visa extended. visa和extend有主谓关系但 he 是句子的主语。
所以 sb get sth done是某人使某事被做

get sth done 让某事被（别人）做

如果按照你的意思，应该是extension.不是externding.有名词应该用名字。

extended不是过去式，-ed在这里可以理解为被动。he get his visa extended可以解释为he let sb. extend his visa. get sth.done是固定用法
