good at后面应该加什么

good at后接名词、代词宾格或动词ing形式。

1、goodat后面不是加动词原形，应该跟动词ing形式。因为at是介词，介词后面要跟名词或动名词即动词的ing形式例如begoodatdoingsth是擅长做某事。动词ing形式也是一种非谓语动词。ing形式仍保留有动词的特征，可以带有其所需要的宾语或状语而构成-ing短语。

2、good at一般的用法是be good at，翻译为擅长，后接something，表示擅长某事，在某方面擅长，后接doing，表示擅长于做某事。I wondered if I could be good at something.我怀疑自己到底是否擅长做一些事情。
