Ⅴ. Reading comprehension  

A  

A plant makes its own food in its leaves. Water comes to the leaves through the roots. Air goes into the leaves through very small holes. The green coloring in the leaves uses the water and air to make the food for the plant. It also needs sunshine because a plant can make food only when the sun is shining.   Animals and people could not live without green plants. They both eat plants. People and some animals also eat the meat of some animals and these animals eat plants.  

T and F   

1. A plant gets food from its roots. 

2. A plant has very small holes in its leaves for air to come in.    

3. A plant can make its food when it is cloudy.   

4. Water comes into a plant through its roots.   

5. People could live without plants.  

B 

Deserts do not stay the same size. Sometimes they grow bigger. Sometimes they get smaller. The world‟s biggest desert, the Sahara, is in Africa. Right now, the Sahara Desert is growing fast. 

Why is the Sahara growing? In some places, people farm too much. In other places, animals eat all the grass. Or，people cut down the trees. This makes the soil weak. Weak soil lets the desert grow. 

Why is it a problem? People cannot grow food in the desert. People cannot built houses, hospitals, or schools in the desert. So, people must leave their homes. They must live somewhere else.  

What can people do? They can plant trees. They can also farm less. These things make the soil stronger. Maybe the Sahara will stop growing. It‟s a big problem. Many people must work together to solve it.     

T and F 

6. The size of the deserts stay the same all the time. 

7. One of the reasons for the growing of Sahara is farming too much.  

8. Deserts make trouble for people. 

9. Planting trees can help people farm less.  

10. Stopping the growing desert is not a big problem.
