5、阅读短文, 判断句子正误。
Do you know how to move heavy things easily？ Today, we will learn some simple ways.
Move with friends
Moving things together is easier than moving them alone.When you push a heavy box with your classmates, the more force you use, the faster the box will move.If you try to move it alone, you may feel very tired.Use wheels
Wheels are very helpful.When you put wheels under a box, it becomes easier to push.Wheels reduce friction(摩擦), so the box slides(滑动)easily.Many things like shopping carts(推车)use wheels for this reason.Use a bigger force
When you push or pull hard, even heavy things can move.For example, when you push a heavy box with a big force, it moves very fast.A small force can only make things move slowly.(1)、Moving things with friends is easier than moving them alone.(2)、Wheels can help us move boxes more easily.(3)、A small force can make heavy things move very fast.(4)、We can use a big force to move heavy things.(5)、The underlined word "alone" means "by yourselfy". -

13、阅读文章, 完成下列任务。
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.
