Hello, everyone. I'm Jenny. This weekend, we will take a trip to the zoo. So today I want to introduce some rules in the zoo to you. There are many animals in the zoo, so you are not allowed to talk loudly. This will frighten the animals. You can take photos of the animals but the flash can't be used. You can watch the animal close but the animals mustn't be fed by you because the animals must be given special food to eat. Besides ,you can't touch the animals ,for they may hurt you. Please follow the above rules when you go to the zoo. We could be safe if we obey the rules.
