eg.

a. 作表语的现在分词表示主语的特征和性质。 b. 进行时态中的现在分词表示主语正在进行的动作。 eg. The situation in our country is encouraging. （表语） The situation in our country is encouraging the people.
不定式（不带to）： 动作发生了，全过程已结束 eg. Do you hear someone calling you?
Yes, I did. I heard him call me several times. You mean you hear your name called several times.
◆ 动名词或不定式作表语: 表示主语的内容，表语和主语的位置可以互换。
