2．阅读理解。

How do animals communicate (交流) with each other? They have special languages. In fact, they are using signals (信号). Different signals have different meanings.
For example, when a bee (蜜蜂) finds food somewhere, it flies home quickly. It can’t speak, but it can tell others by dancing.Other bees will know where and how far the food is.
Some animals show their feelings by making sounds. For example, when a dog is angry, it barks (吠). At this time,you’d better stay away from it. Birds can make several sounds to show different meanings. Sometimes we humans show feelings by making sounds instead of by speaking.For example,when we feel painful (疼痛的), we cry“Oh!”or“Ouch!”.
We humans have languages and words. We can communicate face to face by speaking. We can write down what happened in order to remember clearly. We can also send (寄) messages to people far away. But animals can’t.
根据短文内容，判断正（T）误（F）。

( )1. Humans and animals both have their own languages.
( )2. A bee can tell others the messages by singing songs.
( )3. Birds can make different sounds to show different meanings.
( )4. All the animals can communicate with others far away.
( )5. When a dog is not happy,you’d better keep away from it.。
