In Singapore, cultural differences are shown in building styles, shops and in many other ways.

People love walking through a giant puzzle. In a corn maze(玉米迷宫), they can follow miles of paths and run into lots of dead ends before they finally find their way out. The corn maze has been growing for almost 30 years. 

Simple corn mazes began appearing in the 1980s. In 1993, the first big corn maze created for the public to enjoy was made in Annville Pennsylvania, by Don Frantz and Adrian Fischer. Then, in a corntield as big as two and a half football fields, Mr. Frantz created "The Amazing Maize Maze"with the help of his family and friends. When it was done, almost two miles of pathways snaked through the cornfield. Since then, thousands of corn mazes have been created around the world.

For many farmers, a corn maze means a boost(激增) of extra income. During the opening weekend, about 6, 000 visitors came to get lost in Mr. Frantz's maze. Charging only $5 per person, he earned almost $32, 000in two weeks.

Brett Herbst is also a maze designer. In 1999 he set a world record for the world's largest corn maze, an image of the solar system with nine planets in it. He now has a business called The Maize, which has designed more than 4, 000 mazes around the world. "Corn mazes help people connectwith their roots, "he says. "People are so far removed from farm life that they are drawn to something real, something organic. "

Today, a great number of people enjoy seeking fun in a corn maze. Mr. Herbst says, "When we see families on the farm having fun, we know that they are making memories that will last a lifetime. "

①Our body language tells the world a lot about us. But can it change the way in which we see ourselves? The answer is Yes.

②Two scientists, Amy Cuddy and Danna Carney, who know much about body language, did a famous research. According to the result of their research, body language can change the chemistry of our brains. Some high-power body language can make you become confident. For example, you will feel confident when you hold your head high; you will feel confident too when you put your arms out wide as if you have won a race. However, some low-power body language can make you feel unconfident, such as sitting with your arms close to the body, sitting with your legs together or walking with your head down.

③Why do all these happen? The scientists think the reason is that body language changes the amount of something special in our brains. It's called hormone(激素). One kind of hormone can increase your confidence; another kind can increase your stress(压力). But too much stress hormone is bad for learning. It also increases the risk of health problems.

④The result of the research is helpful for your studies. Please remember: try to use more high-power body language in your studies, and you will be confident. That is, always believe you can study well, act as if you were doing well, then you will make greater progress in real life.

Have you ever imagined being able to communicate with your pets at home and have them understand everything you say？It sounds too good to be true，but scientists have started using AIto help communicate with animals. 

Professor Bake told Scientific Magazine that AI allows humans to use technology to watch and understand the sounds and signals animals communicate with so we humans can try to speak back to them. She said trying to communicate in animals' language could be better than teaching them how to use human sign language. AI is already helping us communicate with bats and bees. This could change what we know about these animals and our relationships with them. 

Professor Bake explained how Scientist Tovel had used recordings and AI to understand bats. "Bats have their own language. They often argue over food. They have different names，or 'signature calls'，" she said，mother bats lower their voice when speaking to their babies. Their voice can never be heard with human ears. But AI makes this possible because a computer can be trained to listen like a bat. "

Actually，AI has so far achieved a lot in this field. For example，the computer not only listens but also watches bees' body movement to understand what they are communicating. Bake said scientists now know how bees say things such as "be quiet" or "stop". Scientist Landlof even created a robot Honeybee that entered a bee's home and was able to communicate with other bees when it wanted them to stop doing something or fly. 

On December 9th, 3:50 in the afternoon, many students in China watch TV. It is a very interesting science class from the space station(大空站). They all like it very much!

Zhai Zhigang, Wang Yaping, and Ye Guangfu are the three teachers. And Wang Yaping is the only woman teacher. She is great fun!

First, she says hello to all of the students. Then she lets the students have a look at their "rooms" in the space station. She gets an apple from the fridge（冰箱）．She says, "This apple is in the space station for a long time but it is really fresh. In her class, Wang Yaping helps the students to know much about water in space. She puts a ping-pong ball in the water. The ball doesn't go up but stays in the middle of the water. It is really interesting! Things in the space station are not the same as we know. Many students ask questions about space science. They are happy to help them.

Wang Yaping has a flower. It is from her daughter. She is only five now. She watches her mom in the space class, too! After one hour, the space science class finishes. Wang says, "All of you are flowers of China. One day you can come to space yourselves and find new things about space!"

Today, I am going to talk about life in the future.  {#blank#}1{#/blank#} Will life be like in the future? No one can answer this question.  Today, cameras in space can take {#blank#}2{#/blank#} (photo) of places billions of light years (光年) away {#blank#}3{#/blank#} the Earth.  Science is developing very fast and people know more about space.  With {#blank#}4{#/blank#} help of science, we may also visit {#blank#}5{#/blank#} (that) places.  We may have to {#blank#}6{#/blank#} (leave) the Earth to live in space {#blank#}7{#/blank#} the Earth will not hold so many people one day.  In the future, we {#blank#}8{#/blank#} (travel) very fast by spaceship.  {#blank#}9{#/blank#} (we) spaceships will be as large as a city, and every spaceship will carry more than 10,000 people.  There {#blank#}10{#/blank#} also many buildings in our spaceships, such as hospitals, schools, shops and cinemas.
