    All pets' owners know that pets use their body language to communicate with us. Since they live much simpler lives than we do, they depend on us and they need to express their needs to us. For example, cats do this with their ears, bodies and sounds. Sometimes they simply want our attention, while other times, they are telling us" My food is empty."

    I have one cat. He tells me different things. For example, when his food bowl is empty, he lets out a howl(长嚎). When he is hungry and doesn't find food to cat, he climbs onto my table and walks on it.

Now research shows that 67% of people think they understand what their pets want or need. The more we show our understanding of what they are telling us, the better our pets will be able to communicate with us. Try to pay close attention to what your pet is "telling" you and you will find it is eager (渴望) to "talk" to you.

In many places on Earth the weather changes during the year. These changes are called seasons. 

Spring Spring starts when the day and night are of the same length. The weather gets warmer and sunnier. Trees and plants start to grow. Many animals have their babies in spring. 

Summer Summer begins on the longest day of the year. In the north this is on 21 June. Summer is usually the warmest and sunniest time of the year. Fruit grows on trees and plants. Young animals grow bigger and stronger. 

Autumn Autumn starts when the day and night are of the same length again. During autumn, the leaves change colour and fall from the trees. Some animals collect food before winter comes. 

Winter Winter begins on the shortest day of the year. In the north this is on 21 December. The weather is co lder and in some places there is lots of snow. Plants and trees stop growing. Some animals, like snakes and bears, find places to hide and sleep. This is called hibernation.
