    There are many beaches in Hong Kong. Some of the beaches are the best in the world. There are some toilets (厕所) , changing rooms (更衣室) and stores to buy food or drinks on most of the beaches. People like going to the beaches and have fun swimming. You can swim there without (没有) danger if you follow these rules：

    ◆Never swim alone (独自).

    ◆Don't stay in the water for a long time.

    ◆Never swim after a meal or when you feel hungry or tired.

Remember：A red flag (旗帜) means it is dangerous for anybody to go into the water. A blue flag means that it is dangerous for children.

    Water is the1of all the things we eat and drink. Not many people understand this but2quite true. The human body3go without food for a long time. We've got many examples for this. Yet two4three days without water can usually make people5. Man can't live6water.

    Many people don't understand how7water the human body needs8work well, and many people, especially young people, do not drink enough,9in very hot weather. Our body is mostly water, about 65% to 75%. That is to say about two thirds of our body is water. When we do sports, some of the water will get away from our body.10we don't drink some water, we won't have enough water. If we don't have enough water, we'll feel tired and many of us will get ill. So you know how important water is to us.

    Vienna is a beautiful old city on the River Danube in the center of Europe. It's the capital city of Austria and the center of European classical music. In the 18th century a lot of musicians came to study and work in Vienna.

    In the Strauss family, there were two composers called Johann Strauss: the father and the son. The father, Johann Strauss the elder, wrote and played music for traditional dances, called the waltz. His dance music made him famous all over Europe. The son, Johann Strauss the younger, was also very successful and popular. He wrote over 150 waltzes. In 1867 he wrote The Blue Danube waltz.

    Mozart was another very important composer. He was born in Austria in 1756. Before he was six, he played not only the piano but also the violin. His family took him around Europe and he gave concerts in many cities. He wrote hundreds of wonderful pieces of music. But he became very poor and died in 1791 when he was only 35. Like Johann Strauss, father and son, he was a great European musician, and many people still think his music is perfect.

Future astronauts could travel with emotional support robots

    To help astronauts of the future survive (幸免于) the mental (精神的) challenges that come with staying in space for quite a long time, space travelers‟ tasks could soon be accompanied(陪伴) by AI-powered, empathetic (有同理心的, 同感的) robotic helpers.

    Not only does space travel present astronauts with lots of physical stresses, spending months or years in such a physically demanding (要求高的) place with limited space and the same people can also raise many mental tests as well. According to MIT Technology Review, scientists are working to alleviate astronauts from some of the latter challenges by creating "an AI assistant that's able to feel human emotion and respond (做出反应) with empathy."

    While such a technology would prove itself useful by being able to predict the needs of the

crew members in space and "intervene (干预) if their mental health is in danger," it has the potential to be life-saving when humans choose to explore beyond Earth's gravitational field (引力场) and towards deep space.

    Though astronauts currently on the International Space Station have an intelligent robot to interact with called CIMON, it is short of proper emotional intelligence according to NASA CTO Tom Soderstrom. As a result, a team at the organization's Jet Propulsion Laboratory is working on a more complex (复杂的) emotional support companion that can control a spacecraft's functioning in addition to tracking the crew members‟ behaviours.

    Right now in the lab, an AI-equipped robot called Henry the Helper can be found walking around the grounds assisting visitors who appear confused or lost based on their facial expression. Two more emotionally intelligent robots are expected to be introduced later this year, one of which is said to be able to take part in conversations more complex than giving navigation(导航) assistance.

    The team's final goal is to make a companion named Fiona the Future a reality, an emotionally intelligent cross-platform system. Fiona, if all goes according to the JPL's plans, will help keep astronauts of the future stay mentally fit as they start their journeys to deep space.
