The world's forests become smaller and smaller. People are still cutting down the trees. Why is this happening? There are two reasons—land and wood. People need land for animals and crops. And people want wood. Japan, Europe and North American need wood. There, it is used for buildings or it is made into furniture.

But most places from the forests are not good for animals or crops. The soil (土壤) in the forests is very thin. When trees are cut down, the soil is washed away by the rain or the wind. Soon there is nothing but sand. Then more land will be needed and more trees will be cut down.

（1）、The world's forests are becoming smaller and smaller now.

（2）、Land is used for animals and crops.

（3）、Most places from the forests are good for animals and crops.

（4）、The soil is washed away by the rain or the snow.

（5）、More land will be needed and less trees will be cut down.

Baboons(狒狒) live in Africa. They are like monkeys. Most people think daddy baboons don't know their babies. But scientists (科学家) find that daddy baboons know how to help their babies. The daddy baboons are smart.

Joan Silk is a scientist. She studies the baboons for 3 years. She says the daddy baboons are happy to see their babies. They have big teeth to help the babies to eat hard things. Mother baboons are small. And they live in a place. When a mother baboon gives birth(分娩), she often has only one baby. Baby baboons have fur. They are very cute.

In recent years, there have been many breakthroughs in the AI (人工智能) field. Here, let us see four of the most interesting developments in AI in 2017.

Magic Radio

Want a friend that you can talk to anytime? Then you might like Magic Radio from Microsoft. Magic Radio features a cool cartoon figure. You can talk to it about anything. There is also an app for Magic Radio. With it, you can decorate the cartoon figure and even send it a gift online. Parents can also use the app to talk to their children. Magic Radio also records your life and analyzes(分析) your behavior. This way, it is easy for parents to know what you're doing when they're not around.

Sophia, Robot

Sophia is the first robot in the world to get citizenship(公民身份) in Saudi Arabia. In 2015, a US company built Sophia. She looks and acts like a human woman. She can talk to people naturally. She even has her own body language. For example, she may blink her eyes when she is talking about something funny. She also has the ability to learn from people, books and the Internet. Sophia was designed to have her values. "Don't worry, if you're nice to me, I'll be nice to you."

Samsung's Bixby

Like the voice recognition (识别) system, Siri on iPhones, Samsung has a similar system called Bixby. Experts said that it is smarter than any other similar system. If you once asked it to complete a certain task, it will remember that task the next time you talk to it. For example, you might like to listen to certain music while you're baking a cake. Next time when you tell Bixby " I want to make a cake", it will show you how to make a cake and play music for you automatically.

AlphaGo Zero

AlphaGo is an AI program that plays the board game GO(). Google Company has created a new version of the AI program called AlphaGo Zero. The new AI program is unique in the way it learned to play Go. AlphaGo Zero mastered Go in just two days without any human knowledge of the game. On the third day, it beat AlphaGo by 100 games to zero, becoming the best Go player on the planet.

Many objects in the universe are invisible, but they send radio waves. The radio telescope* thus appeared, and it is considered one of the greatest inventions in the twentieth century. Reber built the world's first radio telescope in 1937. Ryle and Hewish developed radio telescope systems for the location of weak radio sources, and they shared the Nobel Prize for Physics in 1974.

A radio telescope is usually made up of:

One or more antennas to collect the radio waves. Most antennas are made in the shape of a dish to collect and reflect, the radio waves to the sub—reflector, in the same way as a curved mirror focuses visible light to one point.

A receiver and amplifier to receive the radio waves from the sub—reflector, and make these weak radio waves strong enough to be recorded and turned into electronic signals. To make an amplifier sensitive enough, it is usually cooled to, very low temperatures (e. g. as low as —270℃）.

A recorder to keep a record of the electronic signals. Most radio telescopes today keep the signals to the computer's memory disk for astronomers to analyze later.

Radio wavelengths are much longer than those of visible light, and the radio waves from deep space are always weak. To catch Radio wavelengths are much longer than those of visible light, and the radio waves from deep space are always weak. To catch these waves, radio telescopes usually have huge antennas. The sizes of most antennas in use today are around 50 to 300 metres in diameter. The antenna of FAST in Guizhou, China, the latest and largest radio telescope in the world, is 500 metres in diameter, as large as the size of 30 football fields.

To avoid interferences, and keep the telescopes sensitive, radio telescopes are built in places where there are no human radio waves or electronic signals. For example, FAST is 5 kilometres away from the closest village and 25 kilometres away from the nearest town.

Radio telescopes create pictures of the sky, not in visible light, but in radio waves. This is extremely useful, because there are objects that can't be seen, objects that we wouldn't even know without radio telescopes.

SoFi is a special "fish". It is 47 centimeters long. It is all white. It has a small round head. What kind of fish is it? Actually, SoFi is a soft robotic fish. Scientists from MIT made it look like a real fish. They want to use it to study sea animals when the ocean environment changes.

SoFi's skin is made of a kind of rubber. It's soft. The robotic fish's head is 3D printed. There is a camera in its nose and it can take photos and videos underwater. SoFi can swim among real fish. It is quiet. It doesn't scare other fish. It can also turn left and right, and even change its speed.

Although SoFi is not the first lifelike robotic fish, it is the most advanced of its kind, according to MIT scientists. Many other countries have also made robotic fish, including the UK and China. Scientists said these robotic fish can easily get close to other fish. And other fish can even interact (互动) with them.
