第一个句子中2个动词不定式分别做什么成分?第二句中动词-ing 做什么成分?都是pass laws后怎么不同呢?
1. Was he the first president to pass laws to stop slavery?
2.Lincoln had passed laws freeing the slaves.

Answer 1

1.Was he the first president to pass laws to stop slavery?
中 to pass动词不定式作定语,修饰president,词组：the first /last to do sth
to stop:表示结果状语.即:法律的通过导致了奴隶制度的废弃
2.Lincoln had passed laws freeing the slaves.
freeing the slaves=which free the slaves 作定语,修饰laws,free是动词:使..解放
