下定义，在托福写作中是一种有用的“出字”工具，尤其是对那些面对闪烁的光标一筹莫展无从写起的同学，或是日夜挣扎在独立300字数线的盆友。如能勤快一点，记十个八个（独立作文题目涉及的）常用概念的定义，考试的时候凡能用到某个这样的定义句，噼里啪啦先打出来，看着这一两行甚至三四行文字，心里自然能踏实许多。因此，这样的句子就被称为“镇魂句”了。

在此，男哥整理了若干托福独立题目中常涉及到的概念并给出难易适度的定义，分享给同学们。

常在托福独立写作的课程体系中讲到“下定义”这个工具，无论是开头（“天下大势”型）还是主体段落（“explanation”部分中的“下定义”工具）都能祭出这招，而且用的得当的话，效果非常不错，也可以有效填充文章内容。最近，给小黄子上课的时候重提了这个工具。这一次，干脆把概念变成实践，整理出一个basic catalogue of basic concepts。

整理这些定义的时候，原则是“用户友好型”，也就是常用、好懂、好记、难易适中。这些定义句的内容参考了字典、百科、网上资料等处的释义，但是删掉了过于技术化和学术化的描述，必要时调整和改写之。一些不容易找到“接地气”或“托福化”解释的定义句，男哥就自己动手丰衣足食地“创造”了。

接下来就是这个定义句的list，其中，有阴影的部分就是这些常用概念名词（如telephone ），而整个句子就是对这一概念的定义。每个定义句的后面，有该句可能用到的独立作文题目举例，都出自近期托福机经，极有实用性。
