       Look at these boys. Each of them holds a stick (棍子), and wears a tiny moustache (胡子) and a pair of

glasses. They cover their heads and bodies with white cloth. They look just like Mohandas Gandhi, one of the

greatest leaders in India.

       Gandhi was born in 1869. At that time, India was under British rule (统治). The British did not treat (对待)

the Indians fairly. Gandhi wanted to change the society. In 1920, he came up with his famous idea of

win its independence (独立).

children to be thankful to this great leader.
