The Angel of the North

    The Angel of the North is a modern sculpture (雕塑) in Gateshead, Tyne and Wear, England, designed by Antony Gormley. Completed in 1998, it is a steel sculpture of an angel, 20 metres tall, with wings measuring 54 metres across. The angel, like much of Gormley's other work, is based on the shape of his own body.

    According to the artist himself, the Angel of the North symbolises (象征着) the change from the industrial to the information age and stands proudly as a beacon (灯塔) of hope for the future of the region.

    It cost £800, 000 to make, with the money coming from the British government. It took four years to make the sculpture. It was made in three parts, the body, which weighed 100 tons, and two wings, which weighed 50 tons each. Angels are usually thought of being white, as they represent light, but Gormley's Angel of the North is a reddish brown colour. This is because the steel has a special paint to protect it from strong wind.

    The parts of the angel were moved from Hartlepool to Gateshead at night in big trucks. It took 5 hours to move everything, even though the journey is very short. The Angel of the North was put on the hill in Birtley on the 15th of February, 1998.

    The sculpture was made in memory of the coal miners who worked hard in the dark earth below the hill to bring wealth to the North East in the 19th and 20th centuries. It is a sign for Gateshead.

    The sculpture has since become one of the most famous landmarks in England as can be seen in television and film. It is the largest sculpture in Britain. Over 150,000 people come to Gateshead to see the sculpture every year.

    Sending packets, shopping for everyday goods and even building a house, these are new skills that new robots show at the World Robot Exhibition.

①AI（artificial intelligence 人工智能） and machine learning refer to the ability of machines to learn and act intelligently.It means they can make decisions，finish tasks，and even tell the possible future results based on what they learn from data （数据）.

②AI and machine learning already play a bigger role in everyday life than you might imagine.Health care，banking，video games，every search on the Internet you make...，all are driven by AI.

③AI is going to change almost every field of modern life.Stephen Hawking said，"Success in creating AI would be the biggest event in human history."And Hawking added at once，"Unluckily，it might also be the last，unless we learn how to avoid the risks."

④ ▲  ， especially when you consider some countries are racing to develop AI—enabled autonomous weapons（人工智能自主武器）.It is also going to change and take the place of many human jobs.The same worries also come from the public.According to the survey result from Centre for the Governance of AI，91%of the people （tend to and totally） agree that "AI is a technology that requires careful management" in Europe.

⑤But rather than agreeing with an idea of a helpless future where all human jobs are given over to robots.some people believe AI will make on working lives better.It will improve the work of humans，and new jobs will appear to take the place of the old ones.

⑥What's more，machines become more intelligent and they are able to finish more human tasks.Things which only belong to humans like creativity and critical （批判性的） thinking，will become even more valuable in the future.

⑦Like it or not，AI is here.Maybe changing ourselves and managing it well are the best way out .Just as Benjamin Franklin once said，"When you're finished changing，you're finished."

World Bee Day falls on May 20 every year. And we have been celebrating this day {#blank#}1{#/blank#} 2018. This day reminds the importance of bees and beekeeping. Bees play a role in keeping people and the planet healthy. {#blank#}2{#/blank#} few people know how helpful these little insects are. Bees pollinate（为……授粉）about 75 percent of the world's crops. The insects help to keep the balance between life forms and their environment. 

However, scientists say there {#blank#}3{#/blank#} more challenges for bees today. They include climate change, illness and habitat（栖息地） loss. According to the United Nations, about one million bee species are dying out. 

What can we do to {#blank#}4{#/blank#} bees then? Well, you don't have to be a beekeeper to protect them. Here are some easy choices. You can grow more bee-friendly {#blank#}5{#/blank#} and other plants. Don't cut the grass or use pesticides（杀虫剂） too often. Instead, let the plants grow wild. This way, you can make a more bee-friendly environment!
