答案与解析：
1.B
substantively 实质地 ;substantially 大量地 ;substitutively 可替代地 ;subjectively 主观地 。本句意为经过几个世纪，阅读的概念已经改变了很多。
2.C
在这里to是介词，后接名词或动名词。因本句中the reading process前也应有动词，故选动名词。
3.A
although表示 尽管 ，符合句意。
4.A
involve使卷入、包括;被动语态时用be involved in;没有involve to和involve of的用法。
5.D

actually 事实上地 ;practical是形容词，不能修饰动词。这里actually和前半句的theoretical是在词意上的相对，符合句意。
