There are many elective (选修) lessons for the students in Zunyi No.12 Middle School. Here are the colorful classes in Grade 7 this term:

There are many different kinds of animals in the zoo. We see the zoo keeper give them food to eat. They don’t have to find food by themselves. They can eat, walk and play all day. So many of us may think the animals are very happy. But most of them are sad, why? Because they are not free.

Animals like elephants, monkeys and tigers usually live happily in forests or mountains. Tigers, for example, run, jump, play with their children and they catch small animals for food, but now they have to live in small rooms in the zoo. Baby animals can’t sit together with their parents. Their life in the zoo is different from their life in the forests. Now many people think animals should go back to forests and mountains. I agree (同意) with them. Then the earth will be more beautiful.

Many people love to drink coke. But they don’t know it has many other uses (用途).

You can use it to wash your hands and your clothes. When you wash something, you can put some coke into the water. Then you can wash it well.

Put some coke on the meat when you cook it. And you can cook chicken with coke, too. It’s very delicious and it’s my favourite food.

Coke is good for girls. Use it on your hair and your face, and you will find they are very smooth with coke’s help.

Your flowers may like to drink coke, too. If you give some coke to your flowers, they will be better and nicer.

So give coke a try. If something can’t do it, coke can.
