These feelings are commonly known as dizziness(眩晕). Feeling dizzy is not an illness. _________ Not getting enough sleep, suffering from heart problems or spinning for a long time can all lead to dizziness. However, the figure skaters seem different. When the music is on, they glide(滑行), jump and spin. One turn, two turns, three turns…—it seems that they never get dizzy no matter how many times they spin. Why? We often feel dizzy and lose balance after spinning around. This is because when we move our heads during a spin, our eyes start to move in the opposite direction. They reach their limit before our head finishes a full turn, so they turn back to a new starting point. When our eyes repeat this, we get dizzy. Figure skaters don’t have any super power. They get dizzy, too. Their secret is lots of practice. As they train more, their brains get used to the feeling. Skaters also have methods to help them feel less dizzy. One method is called “opposing eye movement”. It’s like the eye movement when we watch a moving train pass in front of us while our heads stay still. Skaters can train themselves to have this eye movement when they spin. This can offset(抵消) the dizziness. There are also other methods. The first one is keeping a uniform speed(匀速). We feel dizzier when our brains feel changes in speed. Skaters can also pick one point to stare at as they stop turning. Some skaters will design a dance move at the end of a long spin. This provides a little break while the dizziness passes. 1．What does the underlined word “spin” in Paragraph 1 mean? A．Jump up and down. B．Be full of lots of noise. C．Turn round and round rapidly.
