Today many people like growing plants at home because the plants help make the indoor environment beautiful and healthy. However, sometimes people may be too busy to remember to water their plants. If you have the same problem, don't worry. Designer Alastair Crompton can help you solve the problem with his amazing product-Plant Pod. It can water itself without any help.

    The Plant Pod is a self-watering container (容器) for small to medium-sized plants inside the house. Alastair Crompton makes it use a very simple process to provide the plant with the water it needs every day. With a Plant Pod, people no longer need to worry about how much water is perfect for their plants to grow. The water in the Plant Pod is enough to last for at least two weeks. So if people are away from home on a short holiday, they don't need to ask their relatives or neighbours to look after their plants. Won't it be great to see your plants welcome you when you are back home after one or two weeks?

    You probably know a typhoon is a large and powerful storm that can cause a lot of rain and wind. Everyone pays attention to typhoons because they can be dangerous. Some typhoons come and go and really don't cause much more trouble than a bad thunderstorm. Others may damage homes and cause some floods that go away on their own.

    Typhoons are always a concern, especially for people who live near the coast. When a typhoon is on the way, weather forecasters can say which areas will be affected. Maybe you've heard people call a typhoon a "natural disaster", but what does that mean? A natural disaster is something that happens in nature and causes big problems, like a typhoon, a tornado(龙卷), an earthquake, or a tsunami. But wherever you live, it's important to remember that there are lots of people looking out for you. In a bad storm or other crisis, this would include not only mums and dads, but also police officers, firefighters, doctors, nurses, and other people who are trained to handle emergencies.

    The word, "photography", was first used in 1839. It comes from the Greek words that mean "to write with light". But photography could only give people static pictures. So scientists were trying hard to find ways to make pictures that can move. They made lots of experiments, but failed again and again. It was Eadweard Muybridge who finally succeeded. He was the first photographer to try this successfully. But how did he make it? It was an interesting story.

    Back in 1872, people didn't know exactly(确切地) whether all four of a horse's hooves(蹄) left the ground at the same time when it was running. A gentleman called Leland Stanford made a bet with his friend about it. Most people believed that a horse always had one hoof on the ground, or it would fall over. But Stanford didn't think so.

    At that time, it was hard to know who could win the bet, because a horse's legs move so fast that it is impossible to tell just by looking. So they needed a way to record the movement of a running horse. Then Stanford offered $ 25,000 to the famous photographer, Muybridge, to help find the answer. In the beginning, Muybridge failed to get clear images, but he didn't give up. He continued to improve his cameras. In 1878, after many experiments, he managed to get a sequence(连续) of 12 photos. One of them clearly showed that all four of the horse's hooves were off the ground at the same time. And when the photos moved fast, people could see a horse running.

    Though Edison is usually considered as the person who created the first movie in 1889, it was the work of Eadweard Muybridge and the bet that led to Edison's invention.

    The world's largest radio telescope was finished on Sept. 25, 2017 in China.

    FAST is a five-hundred-meter telescope. It is also called Tian-yan ("The Eye of Heaven"), with a dish the sire of 30 football grounds, deep in the mountains of southwest China's Guizhou Province. The giant dish is built on a howl-like valley.

    The surrounding area has "radio silence" as there are no towns and cities within a 5-kilometer radius (半径范围) and only one county center within 25 kilometers.

    FAST is made up of 4, 450 panels (面板). The second largest radio telescope is in Russia. The bigger dish will be able to pick up weaker signals (信号).

    The radio telescope is like an ear, listening to tell meaningful radio messages from white noise in the universe. With the help of the telescope, we can receive weaker and more radio messages far away in space. It will help us to search for intelligent life outside of the Galaxy (银河系) and explore the origins (起源) of the universe. "Any of its discoveries will lead to a Nobel Prize," said Joseph Taylor, a Noble Prize winner.

    The FAST project began in 2011. And the telescope is expected to remain the global leader for the next 10 to 20 years.
