aim后面动词什么形式

"aim"后面可以接 不定式（to do）或动名词（doing）。当表示“想要做某事”时，通常接不定式，有时也可以与"aim at doing"互换。当表示“以…为目标”或“旨在”时，可以接动名词或不定式。例如：

1. He aims to go to Beijing University.

2. He aims at going to Beijing University.

3. Their aim is to improve their skills before the competition.

4. The company's aim is to increase market share.

因此，"aim"后面可以根据上下文的不同接不定式或动名词。
