We are going to discuss the way of reading works it is used for real life purposes, and this should give you a better understanding of it.
A. that
B. which
C. where
D. when
答案：
A. that
B. which
C. where
D. when
解析：本题主要考查对句子结构、逻辑关系的理解及引导词的应用。根据句子结构reading works it is used for real life purposes作定语修饰前面的the way；根据reading works与it is used for real life purposes的逻辑关系，空后面句子为状语从句，从而排除选项A. B；根据句子的意思：我们将要讨论阅读在用作真实的生活目的时如何起作用的方法，从而可知正确答案为D。
