Animals are unlike people. They can’t speak. They are not able to express themselves even if they feel pain or sadness. They need people’s help. Now we can learn from Sophie Smith and be animals’ true friends— volunteers working for animals.

On Feb 3 2014 a girl from Massachusetts the US said that circuses (马戏团) should no more use hooks (钩子) or chains on elephants. And the government should do something.

Some elephants are kept in chains. They can’t walk freely. And chains bring them great pain. Some people even use hooks when they train elephants. The hooks are sharp and bring elephants much more pain. Circus actors even push a hook into an elephant’s body to move it along during a show. “After some time the elephant’s skin breaks down. It feels the pain but it can’t say anything. It can’t say no to those cruel people ” Sophie told local newspaper Marblehead Reporter. She also said that it would be bad for children.

Sophie’s love toward animals started a long time ago. Back in 2011 as a sixth-grader she searched for different animal protection groups online and helped them.

So when she spoke in front of 70 people at the state house Sophie was not afraid. She was full of courage.

“Elephants aren’t treated with kindness. Since they cannot talk I speak for them. I give them my voice and my love ” she said.
