A charity sale was held in our school playground in last Sunday. We prepared many things making by hand, such as kites and model planes. We also brought old toys or second- hand books to sell. When the activity started , lots of students participated in them and chose their favorite items. In end ,we made 2,000 yuan in all. We donate the money to the community to help children who couldn’t attend school.

When people see machines that respond like humans, or computers that perform amazing feats of strategy, they sometimes joke about a future in which humanity will need to accept robot overlords. But buried in the joke is a seed of unease. Science fiction writing and popular movies have shown us about artificial intelligence (AI) that exceeds the expectations of its creators and escapes their control, eventually outcompeting and enslaving humans or targeting them for extinction(灭绝).
Even in the real word, not everyone is ready to welcome AI with open arms. In recent years, as computer scientists have pushed the boundaries of what AI can accomplish, leading figures in technology and science have warmed about the frightening dangers that artificial intelligence may pose to humanity, even suggesting that AI capabilities could destroy the human race.
But why are people so frightened about the idea of AI?
Elon Musk is one of the famous voices that have raised red flags about AI, In July 2017. Musk told attendees at a meeting of the National Governors Association, I have exposured to the very cutting-edge Al,and I think people should be really concerned about it.I keep sounding the alarm bell. But until people see robots going down the street killing people, they don't know how to react, because it seems so impossible."
Earlier, in 2014, Musk had labeled AI "our biggest existential threat," and in August 2017, he declared that humanity faced a greater risk from AI than the terrorists. Physicist Stephen Hawking, who died on March14, also expressed concerns about AI, telling the BBC in 2014 that "the development of full artificial intelligence could spell the end of the human race.

The morning after an evening flight with my then three-year-old daughter, I couldn’t wait to get her to school. I was tired from the anger, and her inability to communicate because of her slowed language development.
As I accompanied her into the car, I felt desperate. Nothing was right with our world. She had been born around the same time the nation was witnessing the birth of another Great Recession(经济萧条）.My job and my house had been victims. Then this happened. My child’s language delay was identified, but doctors struggled to properly diagnosis her. I felt like we both needed to be rescued.
I returned that afternoon as disenchanted with the little girl I loved as when I left.
Walking slowly toward the school’s playground gate, I found her preschool teacher racing to greet me.
“You should have seen her today!” His breathy words were supported by excitement. I didn’t interrupt.“See that climber.”He pointed to a piece of wooden playground equipment that looked like a rock wall. I nodded. “Well, every day since she started school, She’s tired and failed to make it to the top.” He took a breath. “And today she made it.
He expressed his joy just like he'd witnessed her conquering (征服) Mount Everest “”She cheered and celebrated! I wish l'd recorded it.” . His words comforted me. My daughter had conquered her mountain.As she ran toward me, I recognized something I hadn't before. I saw her perseverance. I saw her strength.I saw a hero.
