四. 阅读短文，判断句子正误，正确的写“A”，错误的写“B”。

Pushes and pulls

What is a force? A force is a push or a pull that makes things move. You make things move every day when you play soccer, push a shopping cart or pull mittens onto your hands!

What is a push? A push is a force that moves things away from you. When you push a basketball towards the hoop, you use a push force. When you push with force, things move away.

What is a pull? A pull is a force that moves things towards you. When you pull weeds out of your yard or pull a tissue out of a tissue box, you use a pull force. Things move towards you when you pull.

Forces can be strong or weak. How far you can push something depends on how much force you use. A stronger force makes a bigger change.

 

(1) (    ) A force can be a push or a pull.

(2) (    ) If you pull an object, it will move away from your body.

(3) (    ) We use forces when we play soccer.

(4) (    ) A weak force can create a bigger change than a strong force.

(5) (    ) When you pull a tissue out of a box, it moves towards you.

(6) (    ) Forces can only be strong; there are no weak forces.

五. 阅读短文，选择正确答案。

Speed and force

Speed tells us how fast things move. Different things move at different speeds. A tortoise moves very slowly. A horse runs faster than a tortoise. A car runs faster than a horse. A high-speed train runs faster than a car. A plane moves the fastest of all.

Force can change how fast things move. If you push the door with a small force, it opens slowly. If you push it with a big force, it opens much faster. If you want to run faster, you need to use bigger force to move your legs. In short, a bigger force helps things move faster.

 

(1) What tells us how fast things move?    A. Speed.  B. Force.  C. Time. 

(2) Which moves the fastest according to the passage?    A. A high-speed train.  B. A car.  C. A plane. 

(3) What happens if you push a door with a small force?    A. It opens fast.  B. It opens slowly.  C. It doesn't open at all. 

(4) What do you need if you want to run faster?    A. Smaller steps.  B. Bigger force.  C. Lighter shoes. 

(5) Which of the following is TRUE?    A. A horse runs faster than a plane.  B. A car runs slower than a tortoise.  C. Force can change how fast things move. 

六. 按要求改写句子。

1. A force makes things move.（改为一般疑问句）

 

2. A big force causes a big movement.（对划线部分提问：A big force）

 

3. A horse is heavier than a tortoise.（改为同义句）

5. We can change the speed with force.（改为否定句）

 

【拓展练】

七. 阅读拓展短文，完成下列各题。

What is gravity?

Have you seen photos of astronauts in space? They float everywhere inside their spaceship. Why do they float, but we stand safely on the ground? When you drop an apple, why does it fall down instead of flying up? The answer is gravity.

Gravity is a kind of force. It is a pull that draws all objects to each other. Big things have a stronger pull. The Earth is very big, so it pulls all people and things to its centre. That's why apples drop to the ground, and we do not float away.

A great scientist called Sir Isaac Newton studied gravity hundreds of years ago. Scientists still use his ideas today. The Earth's gravity is strong enough to hold the Moon near us. That is how we can see the Moon in the sky every night.

 

(1) What makes apples drop to the ground?    A. Wind force.  B. Gravity.  C. Friction. 

(2) Who studied gravity and wrote down his ideas long ago?    A. A space pilot.  B. A modern doctor.  C. Sir Isaac Newton. 

(3) Why does the Earth pull every object on it?    A. Because Earth is big; big things have stronger pull.  B. Because Earth floats with the Moon.  C. Because Earth creates wind. 

(4) Gravity is a kind of ______.    A. push  B. pull  C. speed 

(5) (    ) Astronauts float in space because there is no air there.

6. What strange thing will happen if there is no gravity on Earth?（用1-2句话回答）
