句型剖析
句中的 exploring space 是动词 - ing 形式作主语。其用法如下：单个的动词 - ing 形式作主语，谓语动词用单数；
用 it 作形式主语，动词 - ing 形式后置作真正的主语。常用于“It is no use doing...”“It is no good doing...”“It is fun doing...”“It is a waste of time doing...”等句型中；
动词 - ing 形式的复合结构作主语。当动词 - ing 形式有自己的逻辑主语时，常在前面加上一个名词或代词的所有格作动词 - ing 形式的逻辑主语，构成动词 - ing 形式的复合结构。
