SAT(Scholastic Assessment Test)是美国高中生进入美国大学需要参加的考试，也就是美国的“高考”。近年来，越来越多的准备去美国读本科的中国高中生开始参加SAT的考试。 SAT写作是整个SAT考试的第一部分，要求在25分钟内写完。很多高中生反映写不好SAT作文，得分很低。在接下来的几天里，我会将我评改的一些SAT 习作放到这里，供同学们学习和借鉴，希望对准备参加SAT考试的同学有一些帮助。

Tryon Edwards took a firm stand, saying that “if you would thoroughly know anything, teach it to others. One who ceases to learn cannot adequately teach.” It means that teaching something to another people can help people learn a subject well. To me, I definitely believe it is true[1]--- teaching can make the teacher master a process better---because I have experienced and read such things in my daily life.

本段评点

这一段话虽然立刻表明了作者自己的立场，但是内容不饱满，大多叙述是重复和多余的。比如，It means 这一句完全是多余的。Tryon Edwards说的话本来很明白，浅显，不用再解释一遍。或者，可以说自己的那句解释，但是不用引用Tryon Edwards的那句话。
