In most parts of the world, many students help their schools make less pollution. They join "environment clubs". In an environment club, people work together to make our environment clear.
Here are some things students often do.
No-garbage lunches. How much do you throw away after lunch? Environment clubs ask students to bring their lunches in bags that can be used again. Every week they will choose the classes that make the least garbage and report them to the whole school!
No-car day. On a no-car day, nobody comes to school in a car— not the students and not the teachers! Cars give pollution to our air, so remember: Walk, jog, bike or run. Use your legs! It's lots of fun!
Turn off the water! Do you know that some toilets can waste twenty to forty m3 of water an hour! In a year, that would fill a small river! In environment clubs, students mend those broken toilets. We love our environment. Let's work together to make it clean.

Chopsticks are an important tool to have meals in China.

When were chopsticks invented?

{#blank#}1{#/blank#} They were invented before Shang Dynasty. The earliest   chopsticks were made of bronze (青铜). They were 26 centimetres long and 1.1 to 1.3 centimetres wide. People used them to pick up food at that time.

{#blank#}2{#/blank#}

Most people believe that Chinese invented chopsticks. There are many stories about the inventor of chopsticks. Someone says that Jiang Ziya, a wise man, created chopsticks. Actually, no one knows for sure. We can only say that the inventor was a clever ancient Chinese.

What shape are chopsticks?

Chopsticks have the shape of being square above and circle below. Chinese believe that the Earth is square and the sky is circle. {#blank#}3{#/blank#}

How are chopsticks used?

Many people think it's difficult to use chopsticks. {#blank#}4{#/blank#} Hold them between the thumb and other fingers. The key is to hold one piece tight and move the other to control movement and force. Remember, practice makes perfect.

You may have a house robot that can do housework for you. But is it so smart?Met Laura,a robot in the National Library in Madrid. Spain,copying out the old books and writings in its collection. See Aurora,a headless dog-sized robot used to keep birds and other animals away at an Alaskan airport. Watch another 1. 8 meter-tall legless robot called EveR6,waving its arms to guide musicians through a performance. 

Those robots above require artificial intelligence(AD)(人工智能). AI is a computer system(系统)that can understand languages,make decisions and solve problems. AI can be taught skills using a process called machine learning. Humans give AI information such as books,photos or videos to train it. The more information it studies, the better it can do its job. 

_________ For example, when you watch TV,Al is watching you. It'll know what your favorite is and suggest similar ones. In hospitals,AI is very good at suggesting treatments and can even invent new medicines. To cut down food waste,some schools introduce online systems for the students to choose meals ahead of time. In cities, AI is used to watch out for cars that make black smoke. It works together with the police and transportation teams to stop them and keep the air clean. Al can help us fight climate(气候)change by finding clever ways to reduce energy use. 

Some people worry that AI will take away a large number of jobs and also fear that AI could develop out of our control and bring danger to humans. However,AI is expected to be a more powerful production tool that will help humans achieve more in less time. It is believed that the flying car will be made to offer an easier way out of the morning traffic jam(交通堵塞). Humans imagine AI might even use a way to solve the problems of our energy needs completely. Anyway,there is still long journey for humans and AI.
