阅读下面短文,简略回答问题。
Have you ever wished you could talk to animals? Scientists have been trying to find ways to do that! Understanding how animals communicate can help us learn more about them and their world.
Body Language
One way scientists communicate with animals is by learning their body language. For example, when a dog wags its tail (摇尾巴), it usually means it is happy or excited. By watching the body language, scientists can understand how animals feel.
Sounds
Animals also use sounds to communicate. Birds sing to the birds they like or mark their territory (领土). Scientists record these sounds and study them. They try to find out what each sound means.
Training and Sign Language
Scientists have trained some animals to understand human orders. For example, they teach dogs orders like “sit” and “stay”. Some apes (猿类) have even learned sign language. Koko, a famous gorilla (大猩猩), learned over 1,000 signs. She could ask for food, show her feelings, and talk about things around her.
Smells
Many animals use smells to communicate. Ants leave chemical trails (化学痕迹) to help other ants find the food. Scientists study these smells to understand how animals find each other, find their homes, and even know if another animal is sick.
