“Colour” and “color”, “favourite” and “favorite”···Have you ever wondered why Americans spell those words without a “u”? Is it because they are lazy?

Of course not. In fact, the difference in spelling was created by Noah Webster (1758—1843). He is a teacher who reformed English to make American identity stronger. Linguists（语言学家） celebrated his 250^th birthday on October 16. After the Revolutionary War(1775—1783), Webster believed that Americans should have their own dictionary, rather than rely on British versions（版本）. He dropped the British “u” in some words. And he changed “centre” into “center” for children to learn English by spelling words more like they sounded.

Webster wasn’t shy about expressing his opinions. In defining（定义） preposterous, he wrote: “A republican government in the hands of females is preposterous.”

Webster spent 28 years on the project before completing the 70,000-word dictionary in 1828 with his American-style spellings. He also added local words. His dictionary was widely used in schools. Linguists believed it helped a new nation achieve unity and cultural independence at a time when most were focused on political freedom.

“He was the shaper of our language and the shaper of American identity,” said Joshua Kendall, who is working on a biography（传记） about Webster. “He at last bonded（联合） us through our language.”

某35kV电气装置工程项目，施工项目经理部为了保证施工项目按期完成．使资源配置尽量达到合理和最大程度地降低成本，就组织人员进行施工进度计划的编制，编制采用的方法是横道图施工进度计划。
在施工过程中的部分施工工序和要点如下：
(1)坚持先交接试验后通电运行，先接电起动后模拟动作的原则进行。
(2)在做电气交接试验时，高压电气部分做绝缘强度和继电保护试验。
(3)在做电气交接试验时，低压电气部分主要是做继电保护试验。
(4)在负荷试运行时要根据工程师的要求决定是否要联合编制负荷试运行方案。
(5)所有电气试运行时必须在空载状态下进行。
(6)电气设备安装技术人员应配合土建工程进行预留和预埋工作。
