◆正常结构是 make a situation possible：动+宾+宾补。因宾语 situation 太长（含有一个定语从句），为了句子匀称，把宾补 possible 前置。假如把possible 放在后面，看上去句子不平衡，而且会致使误读。
Shopping environments will themselves become a part of the advertisingprocess. （themselves）
◆themselves 是主语 Shopping environments 的同位语。地方一般紧挨着前面的同位成分，也可放在be动词或助动词之后。又如：
Shakespeare was himself an actor.
an actor 是 was 的表语。himself 是 Shakespeare 的同位语。也可以说：
Shakespeare himself was an actor.
Shakespeare was an actor himself.
They are not necessarily the bland documents some bosses might thinkthey are!（necessarily）
◆not 修饰 necessarily，放在之前，地方固定。“不必；未必”
