The Secret of Kites：Push and Pull Work Together
Do you know why a kite can fly in the sky? Because it has two common forces in our life — push and pull.
When the wind blows, it gives an upward(向上的) push to the kite. This pushes the kite up and makes it fly higher and higher.
When you hold the kite string(线) tightly, the string gives a backward(向后的)pull. This pull balances(平衡)the wind's push, so the kite can fly.
So when you fly a kite, feel the tight string in your hand — that's the pull.Watch the kite fly up — that's the wind's push! These two simple forces work together to make a beautiful sight in the sky.

A、The wind's upward push. B、The string's backward pull. C、The child's voice.(2)、Why can the kite stay in the sky？A、The kite is very light. B、The two forces(push and pull) balance each other. C、The string holds the kite directly.(3)、What's the meaning of "tightly" ？A、快速地 B、紧紧地 C、松快地(4)、What will happen when the wind blows hard and you hold the string tightly？A、The kite will fall down to the ground quickly. B、The string will break because of the strong wind. C、The push and the pull will work better to balance the kite.(5)、任务二：When do you use forces in your life？ Please write down one example.I often. When I, I use a bigger / smaller force. It makes things.
