精度textA,textB泛读。textA主要分三部分:1-2,3-4,5-结尾。

1. A decision is a choice made from among alternative courses of action that are available.
made 是过去分词，作choice的定语，可改为定语从句which / that is made …，from among是双重介词结构，除from以外，还有until、but、except后面可再跟介词短语。
2. The purpose of making a decision is to establish and achieve organizational goals and objectives.
该句中to establish and achieve …是不定式短语，充当句子表语成分。
3. The reason for making a decision is that a problem exists, goals or objectives are wrong, or something is standing in the way of accomplishing them.
句中介词for与前面名词reason搭配，表示"…的理由"。另外，当reason充当句子主语时，该句表语从句必须以that引导。句中in the way意为"妨碍、阻碍"，way的搭配还有on the way（在…的路上）、by the way（顺便问一下、顺便说一句）。
