As we know，there are differences between Western culture and Chinese culture.    44    Let's look at some 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 bad meanings.     45    In English, people use the dog to describe good 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.     46    But in Western culture, “cat” is often used to describe a woman who is unkind. There are many other examples of how “cat” is used differently as well.

    47    People think the rose stands for love, peace, courage and friendship. And the rose is the national flower of Britain，America and many other countries.

    48    We can learn about many differences in cultures by comparing how some words are used.

Nowadays many new and useful inventions have come into use. If I were a scientist, I would have my own invention——a magic door, a door that can take me to every part of the world, just like Doraemon's magic door.

Since our life is getting busier and busier, my magic door is really needed. The population of the world is rising day by day，and the number of cars used is getting larger. Therefore，the traffic jam becomes a big problem to people in both poor and developed countries. Moreover，by using a large number of cars，people have to face another problem：the pollution of air. All those reasons lead to the need for such an invention as a magic door. It can take the place of the traditional ways of transportation.

Magic doors have many advantages. Firstly, you can go wherever you want in a minute. Just open the door and go through it，you can stand in another place. Two parts of the door are two parts of the world. Thus, magic doors can meet the need for discovering new places for people. Secondly，magic doors sometimes can even make people safe. Magic doors can be used in everyday life. If you dropped into a river accidentally, for example, people would go there immediately to help you get out of danger by using magic doors.

All in all, people can benefit（得益）a lot from magic doors. If magic doors were invented and came into use widely，not just imagination，there would be a big change in our life！
