【正确答案】 A

【答案解析】解析：根据语义“所有教职人员的参与是______的”，四个选项都可以作为备选答案。作答时不能仅根据空格所在句进行选择，而应对全文进行整体把握。后句中提到“因增加了新的特色，教职人员有必要对这些变化有所了解”，因此可推知教职人员参加培训研讨会是被要求的。故形容词(A)required(被要求的，必需的)为正确答案。另外，“be required to+动词原形”(要求做……，应该做……)可作为惯用语一同记忆。(B)optional意为“可选择的”，(C)unlimited意为“无限制的”，(D)helpful意为“有帮助的”。

【正确答案】 D

【答案解析】解析：此句主干成分完整：every department is strongly advised，故应将“______professors…the month”看成修饰成分。此修饰成分中包含谓语may attend，故可引导修饰成分，构成“尽管教职人员可在一个月内的任何时间参加培训，但强烈建议各个院系针对本院教职人员准备专门课程”之意的状语从句引导词(D)Although(虽然，尽管)为正确答案。如使用(A)If(如果)或(B)After(在……之后)，则语义不通顺。(C)All(所有)作为表示数量的形容词可在可数名词复数形式前使用，但不能引导句子。

【正确答案】 B

【答案解析】解析：“______to each department”作为修饰前面名词specific functions的从句，名词和从句之间的“关系代词+be动词”(which are)可以省略。此时，其后如果接名词，则与先行词构成同位语；如接形容词，则对先行词进行说明。此处意为“适合各院系的”，故形容词(B)appropriate(适合的)为正确答案。如果选名词(C)或(D)，则与先行词(specific functions)在语义上构成了同级，所以不正确。作为参考，一般省略“关系代词+be动词”的情况，其后接形容词的频率比接名词的频率高。
