英语作文中常用的逻辑词【一】
也叫下定义。有时为了突出事物的主要内容和主要问题，往往用简明扼要的话给事物下定义，使读者对被说明对象有个明确的概念。例如《统筹方法》一文中，作者运用了下定义的说明方法，给统筹方法下定义：“统筹方法，是一种安排工作进程的数学方法。”语言简明、扼要、准确。英语作文中常用的逻辑词【二】
推理是由一个或几个已知的判断（前提），推导出一个未知的结论的思维过程。在体育教学中会经常接触到，但是很多很常见的体育教学中的推理确实非常不符合逻辑的。例如我们经常听到体育教师这样评价一个班级：“A班同学体育成绩都好。”归其根源：A班有几个体育特长生。一个由特称判断推理出的全称判断，两个差等关系的判断却被教师这样误读了。又或者在对两个学生进行比较或者进行体育选材的时候经常会见到类比推理，即依据两个或两类对象一个一个的属性相同，并已知其中一个对象还有其他属性，推出另一个对象也具有该属性的结论。例如A同学和B同学，同样身材高、学习成绩优秀、A同学已在篮球上取得了一定的成绩，于是体育教师就同样断定：B同学一定可以在篮球上有所突破。当然，让B同学来尝试是可以的，但是作为两个活生生的人来说，切不可用此类类比推理，不仅不符合任何科学逻辑，也会在一定程度上降低体育教师的能力和威信。

英语作文中常用的逻辑词【四】
判断是人们对于客观对象是否具有某种属性的认识。在体育教学中主要体现在教师对学生的评价上。在评价体系上可以多选用一些相容选言判断，学生某一项达到一定要求就可以算其成功。例如：学生50米及格或者100米及格或者400及格均为体育成绩及格。这就在一定程度上增加了学生的选择性，也增加了评价体系的人性化，不至于过于挫伤学生对体育的热情。又或者，在教学过程中教师对学生的表现进行判断，经常会听到“你必然篮球打不好。”等真值模态判断，常用这些真值模态判断等于从能力取向对学生进行评价，尤其是对小学生来说，他也会在同时降低对自己的能力判断，会对学生产生一定的不良影响。
