问题补充:
The bookten units, two revisions.
A. contains; including
B. includes; containing
C. includes; contained
D. contains; included
答案:
A. contains; including
B. includes; containing
C. includes; contained
(答案→)D. contains; included
解析:考查contain和include用法辨析。Contain表示包括的全部内容,即该词后面的宾语只是所包括的全部内容,include表示包括的部分内容。句意:这本书包括了10个单元,包括了两个复习单元。因为two revisions与include构成被动关系,故使用过去分词的形式。故D项正确。
