Words fail me to describe the joy of showing these amazing works to such a rapidly growing audience.

当我给这么一大群听众讲解这些令人激动的工作的时候，我真的兴奋地无以言表。

I straightened suddenly. I admit that I was less than ready for this announcement. I wanted to reply to the Canadian, but words failed me.

我突然站起来。我但白地承认，我一点也没有料到他会告诉我这个消息。我要回答加拿大人，但又找不出什么话来说。

Words failed me to express my feelings.

我无法用语言表达我的感受。
