     As we know, there are differences between western culture and Chinese culture. We can see differences

when we pay attention to the way words are used. Let's look at the words about animals and plants. Most

expressions in Chinese about the dog, for example, "a homeless dog","a mad dog","a running dog" and "a dog

catching a mouse", have negative* meanings. But in western countries, dogs are thought to be honest and

good friends of humans. In English, people use the dog to describe positive* actions. For example,"you are

a lucky dog" means you are a lucky person. And "every dog has its day" means each person has good luck

sometimes. To describe a person's serious illness, they say"sick as a dog". The word "dog-tired" means very

tired. However, Chinese love cats very much. But in western culture,"cat" is often used to describe a woman

who is cruel*.

     The rose is regarded as a symbol* of love in both China and some western countries. People think the rose

means love, peace, courage and friendship. And the rose is the national flower of England, America and many

other countries.
