  2. v. t. e. English is a West Germanic language that originated from Anglo-Frisian dialects brought to Britain in the mid 5th to 7th centuries AD by Anglo-Saxon migrants from what is now northwest Germany, southern Denmark and the Netherlands. The Anglo-Saxons settled in the British Isles from the mid-5th century and came to dominate the bulk of ...

  3. From today's featured article A 56-bell carillon A carillon is a pitched percussion instrument housed in a bell tower and played with a keyboard. Consisting of at least 23 cast bronze bells in fixed suspension and tuned in chromatic order, carillons are usually owned by churches, universities, or municipalities. The bells are struck with clappers connected to a keyboard of wooden batons played ...

    海龟绘图使得Logo用户可以通过简单的编程创作出丰富多彩的视觉效果或图案。假想一只带着画笔的海龟可以接受简单的命令,例如向前走100步,或者左转30度。通过对这只海龟发送命令,可以让它绘制出较为复杂的图形,例如正方形,三角形,圆等。 海龟的移动相对于它本身所在的位置。例如,命令"左90"意味着让海龟左转90度,学生可以站在海龟的角度来思考它将如何执行命令,这使得程序设计更加形象化,也更易于理解。

    设计Logo的初衷是为了向儿童教授计算机编程技能。它亦適合用作數學教學。初学者可以不需要任何程式设计的知识而直接向海龟发送命令。学习海龟作图将会让用户懂得一些关于几何学方面的知识。而一旦掌握了海龟作图的基础之后,引入程式设计的概念也变得更加容易。下面看一些例子:FD是前进LT是左转画一个正方形 由于输入的语句都是重复的,可以用重复语句简化为: 上面两段程序得到的结果相同,由于第一个程式几乎都是重复代码,因此我们用『REPEAT』让Logo重复同样的命令4次,同时还使用了命令的缩写。为了重复使用上述代码,我们可以用『TO...END』定义过程: 一旦定义了『CHAIR』过程,就可以直接使用调用它得到结果,为了使得这个过程更加通用化,我们传递一个边长参数: 从简单地发送绘图命令,到定义一个通用的绘制多边形的过程,用户不但掌握了程序设计上的一些基本思想(传递参数、重复等),而且对几何学上正多边形的理解也加深了。
