4.delight
A:作及物动词： 使高兴
I am delighted that you are back.
你回来了,我很高兴。
I am delighted to read your novel
我喜欢读你的小说
B:作不及物动词：高兴 后面常和介词"in"连用
I delight in reading your novel.
我喜欢读你的小说
分析此句，主句的主语是“I”，状语部分的非谓语动词用现在分词还是过去分词,要看与主句主语是主动关系还是被动关系。
After I was delighted to see your mother.
=Delighted to have seen your mother.
(不定式用完成式表示动作发生在主语谓语动作之前)
祝学习进步!!
