    In choosing a friend, one should be very careful. A good friend can help you study. You can have fun together and make each other happy. Sometimes you will meet fair-weather friends. They will be with you only if you have money or luck, but when you are down, they will run away. How do I know when I have found a good friend? I look for certain qualities of characteristic, especially understanding, honesty and reliability (可靠).

    Above all else, I look for understanding in a friend. A good friend tries to understand how another person is feeling. He is not quick to give his opinion. Instead, he tries to learn from others. He puts himself in the other person's place, and he tries to think of ways to be helpful. He is also a good listener.

    At the same time, however, a good friend is honest. He does not look for faults (过错) in others. He notices their good points. In short, a friend will try to understand me and accept me.

    Another quality of a friend is reliability. I can always depend on (信赖) a good friend. If he tells me he will meet me somewhere at a certain time, I can be sure that he will be there. If I need help, he will do his best to help me. If I am in trouble, he will not run away from me.

    There is a fourth quality that makes a friend special. A special friend is someone with whom we can have fun. We should enjoy our lives, and we would enjoy our friendship. That is why I especially like friends who are fun to be with. A good friend likes the same things I like. We share experience (经验) and learn from each other. A good friend has a good sense of humour, too. He likes to laugh with me. That is how we share in the joy of being friends. And I know that he is looking for the same quality in me.

    When I meet someone who is reliable, honest, and understanding, I know I've found a friend!

    Dubai is a city of big business, expensive hotels, skyscrapers (摩天大楼), and shopping malls. In the early 20tb century, Dubai was a successful trading port. People from the world stopped in Dubai to do business. But it was still a small city, and most people lived as fishermen and businessmen. Then in 1966, oil was discovered. This brought a lot of money into the area, and soon Dubai began to change.

    Today Dubai is one of the world's most important business centers. In fact, each year the city gets its money mainly from business, not oil.

    Recently Dubai has attracted more and more visitors from abroad. They come to relax on its beaches, and every year, millions visit just to go shopping.

    Dubai is also one of the world's fastest growing cities. Many tall buildings are built in months. The city also has many man made islands. One of these, the Palm Jumeirah, is like a palm tree(棕榈树) and is very beautiful.

    The city is still and amazing mix (混合体) of people from different countries. The people from 150 countries live and work in Dubai, and foreigners now outnumber Dubai natives(本地人) by eight to one!

    Many people welcome the city's growth. But an increasing number of Dubai natives worry about the speed of change. As a Dubai native says, "We must always remember where we came from. Our kids must know we worked very, very hard to get where we are now, and there's a lot more work to do. "

    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 are about the dog, for example, "a homeless dog" "a mad dog" "a running dog" and "a dog catching a mouse", having 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 things. 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 some time". 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(无情的) .

    The rose is 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 a kind of important flowers in England, America and many other countries.

    The words about plants and animals are used in positive or negative ways in different cultures. We can learn about many differences in culture by comparing how some words are used.

    When you're closing your eyes and hitting your pillow, you're probably not giving much thought about the sleeping position throughout the night. Most people don't change their sleeping positions throughout their lives. The following is why you might want to pay more attention: Your sleeping position can actually say a bit about who you are and what your personality is like.

    There are many sleeping positions. The fetal (胎儿的) sleeping position is generally the most common sleeping position. Fetal sleepers sleep on their side, they move into a position in which their body makes a rounded shape. People who sleep in the fetal position are often quite sensitive and generally shy. They are often worried or nervous and don't focus their attention on the main problem, but get into trouble on very small pieces of information.

    The log (木头) sleeper rests on the side with a straight body when hands and legs are kept at the sides. These sleepers are often relaxed, but also can easily believe lie-tellers. If you're a log sleeper, you might want to keep in mind that it's good to be easy-going and have less stress, but don't be so quick to go with the flow (流) at all times.

    The third one is the soldier position. Soldier sleepers typically lie on their backs with both arms close to their sides. In general, they are the strong and silent type. However, they can also put the pressure on. "They can be quite strict with themselves as well as others," a scientist added.
