苹果公布莉莎源代码达沃斯论坛主要成果麦当劳顾客拿到钱而非汉堡

　　1)   World Economic Forum’s 2023 Davos   event ends: Here are the major   takeaways  .
　　2023年达沃斯世界经济论坛结束，以下是论坛主要成果。
　　在经济方面，出现了谨慎的乐观情绪，许多人似乎认为最坏的情况已经过去。
　　在气候问题上，谈得很多，但行动很少。
　　通常在年度峰会上表现突出的俄罗斯寡头出于显而易见的原因缺席，而乌克兰则强烈要求提供更多军事和财政援助。
　　论坛今年的主题是＂分裂世界下的合作＂。
　　The theme this year was ‘ Cooperation in a Fragmented World ’.
　　Most business leaders were upbeat about the economy, with US and the European Union (EU) seemingly beyond the risk of a recession now.
　　Everyone agreed upon the need for green energy and the need for more money to flight climate change.
　　2) McDonald＂s customer mistakenly given bag containing thousands of dollars in cash instead of food.
　　麦当劳的一位顾客拿到的食品袋里装了数千美元的现金，而非食物。
　　这事发生在得克萨斯州的一家麦当劳餐厅，顾客点餐之后，员工误操作，把一个装有几千美元现金的袋子给了顾客，而不是汉堡等食品。顾客立即返还现金。
　　为感谢该顾客，麦当劳给了他200元的酬谢和一个月的免费用餐。
　　Although he admits he was tempted to keep it, Vargas is eventually seen in the video walking back into McDonald＂s to return the cash.
　　He said he returned the money to the fast food chain because he is a ＂good person.＂
　　Vargas then walked outside the store and said the employees were crying as they hugged him and thanked him.
　　He said the employees  rewarded him  for returning the cash by giving him $200 and free McDonald’s for a month.
　　3) Apple releases Lisa source code on   landmark machine  ＂s 40th birthday.
　　距苹果发布莉莎计算机已40年了，在这个具有里程碑意义的日子里，苹果公布了莉莎的源代码。
　　施乐发明了第一台视窗商用计算机。乔布斯将此技术引进家用计算机，出品了第一台视窗个人电脑，莉莎。施乐的商用机器价钱是7万5千美金，而莉莎是9995美元（与当时的小汽车价钱差不多），后来的麦金塔则更便宜。
　　The Lisa cost as much as a small car and gave the world its first look at a personal computer driven by a  WIMP interface  – an ＂80s acronym for  windows ,  icons ,  menus  and a  pointer , the latter driven by a mouse.
　　The machine＂s source code has been released under Apple＂s Academic License.
