来看这样一个试验： 如果您已经在心中吐槽，问高中生这种问题是不是太"小儿科"了，那么学生们的答案可能会让您惊掉下 巴：在场80%的学生竟然都回答了"固态"。 在美国某高中的化学课上，化学老师问学生："25摄氏度的水是什么形态？" 原来，"摄氏度"这个概念对美国学生而言实在是太陌生了，英制中的"华氏度"才是他们更为熟悉的概 念。 和利比里亚、缅甸一样，美国是目前全球范围内仅有的几个仍在官方层面或实际生活中使用英制的国 家，连英制的"祖国"英国都改用公制了。 在英制计量系统中，比较常见的长度单位包括英尺、英寸等，常用的重量单位则包括磅、盎司等，且大 多数单位都可以追溯到人体或者日常用品。比如，1英寸据说就是历史上某任国王拇指指节的长度，约 等于2.54厘米；而英尺则与脚的长度有关，后来才演变为30.48厘米的固定长度。 那英制单位间该怎么换算呢？与公制的"1千米"等于"1000米"这样超级简单的换算方式相比，英制单位 间的换算可就麻烦多了。比如，1英尺等于12英寸，1英里等于5280英尺。如果想要在英制和公制之间进 行换算，那就更让人眼花缭乱了——1英里约等于1.6千米、1磅约等于454克、0摄氏度等于32华氏 ...

【文/观察者网 齐倩】 新年伊始，美国失业率居高不下，消费者信心指数已接近历史低点。 但当地时间1月1日，美国沃尔纳财富管理公司创始人丽贝卡·沃尔纳接受福克斯新闻节目采访时仍掩耳盗铃，宣称2026年"将是积极的一年"。她还提 前甩锅，称"只要中国不捣乱，美国就过得好"。 采访中，沃尔纳首先附和美国总统特朗普的预测：2026年美国经济将非常乐观。 "是的，我认为这会是积极的一年，"她说，"我们确实有很多基本面支持这一年的积极发展，但我们仍面临很多全球宏观经济问题和挑战"。 谈及此处时，沃尔纳和主持人为自己的乐观经济预测"打补丁"，提前甩锅给中国。 随后，沃尔纳"自己打自己的脸"，列举了美国经济的"麻烦领域"：失业率和高通胀率。 她坦言，相较于通货膨胀，劳动力市场更是主要问题所在。她希望未来美国政府和美联储继续关注就业，采取措施刺激就业增长。她同时提到，一 些科技公司通过采用人工智能（AI）工具提升了生产率，并将此视作提高成本效益的优点，这给2026年就业率提出挑战。 丽贝卡·沃尔纳（右）接受采访福克斯新闻节目视频截图 沃尔纳声称，对美国来说，2026年能否顺利度过，要看中国是否"制造干扰"。 据半岛电视台报道， ...
