求教语法

求教以下三句的语法：
Hij heeft kunnen (moeten) komen.
Hij is komen (blijven) eten.
Ik heb hem laten (horen) komen.
如何翻译，以及为什么这么用？
先谢谢了

完成时：hebben/zijn + 过去分词: http://www.dutchgrammar.com/en/?n=Verbs.Re13
至于用hebben还是zijn，取决于http://www.dutchgrammar.com/en/?n=Verbs.Au04

当一句句子里有三个及以上的动词时，后面两个动词都使用infinitive形式

翻译:
1) He could have come. He should have come.
2) He has come to eat. He has stayed to eat.
3) I have let him come. I have heard him come.

thanks a lot
