But is it possible for them to communicate with us?

VOA: special.2011.03.22

I feel no superiority over my beloved pets when I look at them in the eyes, and eventually after they lived with me long enough to communicate Fortunately I don't expect them to take my courses.

当我看着我深爱的宠物时,我并不自以为比它们高等，就算后来,我们一起生活很久，都能相互交流了,所幸我并不期望它们来上我的课。

You can communicate like good feeling with them with "I'm glad". So I recommend that you use it a lot.

你可以用“I'm glad”跟他们交流，表示你觉得和他们一起很开心。因此你可以多多使用这个句型。
