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.

Here is a story: A man sees a butterfly (蝴蝶) . The butterfly tries to get out of its chrysalis (蛹) . F{#blank#}1{#/blank#}sorry for it, the man decides to help. He cuts the chrysalis and the butterfly comes out e{#blank#}2{#/blank#}. Surprisingly enough, the butterfly is unable to fly. If the butterfly doesn't struggle (挣扎；奋斗) to leave the chrysalis, it can't fly！The struggle develops the e{#blank#}3{#/blank#} in the butterfly which makes it fly. Similarly, the challenges of life bring out the best in young people and make the fly.

When people are young, meeting and overcoming challenges will make them s{#blank#}4{#/blank#} and ready to face life.

When we look at successful people, we see that the most successful of them are people who have had to struggle.

One famous businessman, who now o{#blank#}5{#/blank#}many big supermarkets, used to carry clothes on his back and sell them from door to door when he was young. Another successful man is Dennis. His father died when he was only twenty. He had to b{#blank#}6{#/blank#}up a big family. He took up the challenges and overcame them. Today his brothers and sisters are leading s{#blank#}7{#/blank#} lives.

Sometimes challenges do not appear to us because we keep away from them. So, some parents and teachers actively encourage young people to face challenges. They might organize some a{#blank#}8{#/blank#}for young people which provide them with challenges, like rock—climbing, camping, volunteer work and so on. However, just passing exams will not prepare a person for life. We must meet and overcome challenges. The young people of today will become the leaders of t{#blank#}9{#/blank#}. For countries to continue to become successful, it is i{#blank#}10{#/blank#}that the young people learn to meet challenges and overcome them.

Many people take running as a way to keep fit. They like to run in hot weather and enjoy the feeling of being wet through with sweat (汗) while running. Cold weather during winter months, with low temperatures and freezing cold winds, may keep people from running in the open air.

However, a new study shows that the drop in temperature is a good reason to run. In fact, running in cold weather helps improve one's performance. Many runners might find it easier to run in winter than in hot weather. The body needs less water on a cold day than in warm weather. In addition, lower temperatures reduce stress on the body. When you run in cold weather, your heart rate is lower.

John Brewer is a professor of applied sports science at St. Mary's University in London. For this study, he and other researchers put a group of people into a room where summer and winter weather conditions are recreated. The test subjects were asked to run 10,000 meters under both conditions and their biological measurements were recorded and studied.From the study, every movement runners make produces heat. The heat can be really damaging unless the body can lose it. One way in which people lose heat is by sweating. The body loses heat through sweat. The body also loses it by transporting the blood to the surface of the skin and it puts more stress on the heart, especially in hot conditions because it's much harder to lose heat when the outside environment is warm. As the result shows, running in hot temperatures results in 6 percent higher heat rates.

When running in cold conditions, the body does not have to work hard to move blood to the skin surface. Therefore, it requires less energy. The most important thing for people who run in cold conditions is to wear the right clothing. Keep as dry as possible when exercising in low temperatures. Wear warm and light clothing to keep sweat away from your skin. So don't let winter weather keep you indoors. Simply get ready for the low temperatures and start running.

When buying a house, most people hope to have nice neighbors. {#blank#}1{#/blank#} People may have different answers (答案). Here are my answers. 

Good neighbors should respect (尊重) each other. {#blank#}2{#/blank#} It's good to greet (和……打招呼) each other. We should never try to learn about others' lives. 

•Good neighbors are always kind-hearted. {#blank#}3{#/blank#} If we are not at home, our good neighbors will keep eyes on our houses. 

•Good neighbors should keep the environment (环境) clean. {#blank#}4{#/blank#}. Keep the floor clean. 

Everyone wants to live a happy life. {#blank#}5{#/blank#} As students, we should all learn to be good neighbors.

A．They always help us when we need them.

B．What is a good neighbor like?

C．Say hello when meeting.

D．I hope everyone can have good neighbors.

In ancient(古代的) China, people(人) have three names: the {#blank#}1{#/blank#} name, given name, and courtesy name(字).

 Look at Li Bai, his family name is Li, his given name is Bai and {#blank#}2{#/blank#} courtesy name is Taibai. Some people call him Li Bai, {#blank#}3{#/blank#} some people call him Li Taibai.

 When do people use their given {#blank#}4{#/blank#} and courtesy names? When(当……的时候) people are at home, they usually use their given names. But when they are {#blank#}5{#/blank#} at home, people use their courtesy names.

Do you like playing cards? Do you know some interesting things about cards? The four suits(花色) mean four seasons: spring, summer, autumn and winter. The two colours, red and black, mean day and night. The 52 cards mean the 52 weeks of a year. In every suit, there are 13 cards. It means 13 weeks in each season.

In China, people like to play "24" poket games. For example, if you get the four cards, you can play like this: 

First, ten minus four is six.

Second, eight divide by two is four.

Then, six times four is twenty- four.

Is this fun? You can use "plus, minus, times, divide by" to make 24. Would you like to have a try?
