完形填空

阅读下列短文,按照要求完成各题,并将答案填在答题卡标号为76-83的空格中。

Skipping rope is a great way for kids to exercise while they have fun. As a student, you can jump alone or with your classmates. You can also help turn a long rope for many others to jump over, one at a time. If you jump alone, you will need a short rope and it should be just long enough for your height. Try ropes of different lengths until you find a right one for our height.

A rope should be turned slowly. It must also be turned high enough to let you jump freely and safely. Turning the rope freely and safely needs careful timing(时间的选择). In rope jumping, timing means turning the rope slowly enough for you to jump over at the right time without striking(碰撞) your feet.

When you jump rope, your heart beats faster and your face has a healthy color. But if you jump too many times at first, you will get tired. You must learn when to stop for a rest before you jump again. If you practice, you can increase the number of times you jump without resting.
