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.

Singapore is a city of different cultures. Walking through the streets of Singapore, you can{#blank#}1{#/blank#} (听到)different languages spoken, such as English, Chinese and Malay. People from different cultures live and work peacefully with each other and share their traditions.

In Singapore, cultural differences are shown in building styles, shops and in many other ways. Take food as an {#blank#}2{#/blank#} (例子), each culture has its own place to sell their traditional food, but there are also the {#blank#}3{#/blank#} (著名的) hawker markets. Different foods are sold in these {#blank#}4{#/blank#} (繁忙的) markets.

And these are very {#blank#}5{#/blank#} (受欢迎的) with Singapore citizens and {#blank#}6{#/blank#} (游客) from around the world. The food is good and very{#blank#}7{#/blank#} (便宜的).

Singapore is also an interesting city. Large numbers of people, ideas, etc, are mixed together {#blank#}8{#/blank#} (在……下面)the same sky. English is used for business, {#blank#}9{#/blank#} (虽然)the official language here is Malay. Now, however, there is a strong Chinese business community and also a growing Indian business community. Singapore welcomes talented people from around the world and {#blank#}10{#/blank#} (希望)they will live there all their lives.

While travelling to big cities in the world, you will see statues (雕像) of {#blank#}1{#/blank#}(thousand) of characters standing in the streets. Do you believe that they are actually real people working {#blank#}2{#/blank#} street artists? They often cover themselves {#blank#}3{#/blank#} (complete) with paint. They have to stand still and keep eyes open for several {#blank#}4{#/blank#} (hour). Street artists need to be strong-minded and patient. It is not {#blank#}5{#/blank#} easy job, but there's plenty of fun for them.

Yorge is one of {#blank#}6{#/blank#}(famous) street artists in Brazil. He stands out thanks to his partner, a cute dog named Jaspe. {#blank#}7{#/blank#} Yorge goes to work, Jaspe rests on his arm and keeps still as long as she can. Most people are surprised by {#blank#}8{#/blank#} (they) perfect work together. However, the pair once got into trouble. Some animal lovers thought that his dog was made {#blank#}9{#/blank#}(give) a performance in the street by Yorge. In fact, Yorge never trained Jaspe at all.

So far the performance of living statues {#blank#}10{#/blank#}(become) a street art. Now it is really popular in many large cities around the world.

Inventions are very important and they can easily change our life. The followings are some great inventions. 

China is a country with many colorful days and festivals. The Dragon Head Raising Day （Longtaitou） is one of them. 

This special day is on the second day of the second month in the Chinese lunar calendar （阴历）. It stands for the start of spring and farming. This year，the day fell on March 10. 

The dragon is important in Chinese culture. We Chinese people call ourselves the"descendants （传人） of the dragon". Therefore，people celebrate the Dragon Head Raising Day with many customs（传统） about dragons. 

On the day in ancient times（古代），people put ashes （灰） in the kitchen. This was to" lead the dragon into the house". People believed that with the help of the dragon（收成） in autumn. 

Also，people eat special foods on that day. The foods are usually named after dragons. For example，people eat" dragon whisker （细须）"noodles and dumplings called" dragon teeth". 

Today，many customs have faded away （消退）. But one that has remained is the cutting of hair. It was said that a haircut during the first lunar month may bring bad luck to the mother's brothers. So many people have their hair cut on the Dragon Head Raising Day. 

Do you like listening to mom？You may say no. Lately，scientists know the reason for it. They find that kids' brains （大脑） enjoy their mothers' words. But when they get older，they like listening to friends' words. 

A scientist named Danel Abram scan （扫描） students' brains （ages from 7 to 16）. When they listen to mothers' words，their brains are active. Students aged 7-12 years answer mom's words more actively. But starting from ages 13 to 14，students talk more with friends. 

Why is this？First，when we grow up，we have more time to study and play with friends，so we think what other people think is more important. Second，this is a time when we think and see the world in our own eyes. 

Next time，when your parents feel sad about this，you can share your feelings and tell them reasons. Anyway，we are sure to grow up and say goodbye to our yesterday's life.
