（单词翻译）

 With a gentle flick1 of the wrist on a warm summer day, you can launch a frisbee2 on a long and graceful3 flight. Why frisbees fly so well? One reason is something called gyroscopic force. This is the tendency of a spinning object to maintain a stable orientation4. If you throw any round object so it spins as it flies–a record album or compact disk for example–it will tend to fly something like a frisbee. If you throw it horizontally, it will stay horizontal for most of its flight. The leading edge of a CD or record is much narrower than its broad, flat surfaces, so this steady orientation helps reduce air friction5.
