【范文】Knowledge
Knowledge is to us what a compass is to a ship. A ship has to rely on a compass to sail safely across an unknown ocean. Similarly, knowledge brings forth power we need to make real progress toward a better life. With knowledge, we can invent new and useful apparatus and machines; we can create beautiful art, including paintings, sculpture, music, and so forth; we can make clothes, furniture, cars, space shuttles and the like. It is knowledge that enables us humans to lead a convenient and colorful life. On the contrary, were it not for knowledge, people would become stupid and uncivilized; everything would get back to the primitive age; no more human history could be passed down. In short, the more knowledge we gain, the wiser we will become.
That is, knowledge is indispensable to mankind. (138 words)
