The mind map uses colourful, tree-like branches to connect ideas. It helps people solve problems creatively, remember information better, and understand things easily. Here are some key steps: 1. Write or draw the subject in the centre. 2. Draw the first branches out from the centre. 3. Move to the next branches. Add some keywords or simple pictures. 4. Use different colours to make ideas clearer. Let’s pick up a pen and give it a try!

(　　)1. What can’t the Mind Map help people do?

A. Make pictures more beautiful.              B. Solve problems creatively.

C. Remember information better.              D. Understand things easily.

(　　)2. What is a first branch in the mind map?

A. a.              B. b.              C. c.              D. d.

(　　)3. Why does the writer write this passage?

Elephants are the world’s largest animals living on land. The African elephants are usually 3～4 metres tall. The Asian elephants are usually 2～3 metres in height. Elephants use their long noses to collect food and to drink water. They can make different kinds of sounds. These sounds can travel for miles and reach other elephants. They usually use the sounds for help.

African elephants are the largest kind of elephants and can weigh up to 6,000 kilograms. Asian elephants may not look that different from their African cousins, but they are quite different. Asian elephants are shorter in height and as a result, weigh less. Asian elephants’ ears are much smaller than African elephants’. Also, Asian elephants rarely have ivory, while African elephants have long ivory.

Elephants are very clever. Many farmers train them to help out in their work as they can carry heavier things, and work can be done much faster. As a result, most farmers love their elephants and treat(对待) them with great care and make sure they are always healthy and happy.

(　　)4. What do elephants usually use their sounds to do according to the passage?

A. To ask for help.              B. To remind each other.

C. To find food.                D. To drive other animals away.

(　　)5. What does the underlined word “rarely” mean?

A. Usually.              B. Clearly.              C. Always.              D. Not very often.

(　　)6. Why do farmers train elephants?
