单项选择题
阅读二：The Penumbra is the shadow of the Shadow. The Penumbra asked the Shadow, "A moment ago you were walking, and now you have stopped; then you were sitting, and now you have stood up—why are you so changeble? Would you seriously make up your mind about what you want to do?"The Shadow replied, "I am just the shadow. I wait for the movements of something or someone else, and then I can follow up. And the very thing or the person that I wait for is also waiting for some other thing or person. A snake depends on its scales (鳞片) to crawl and a cicada depends on its wings to fly. How should I know why I do one thing, or do not do another?"（Adapted from James Legge’s The Chuang Tzu, p.37）
