【正确答案】 C

【答案解析】解析：根据“感谢您有兴趣______携手基金会”的句意可知，各选项都有可能正确，这就需要联系上下文。后文中提到请收信人填好志愿服务表格，并于8月31日前邮寄给写信人，由此可知收信人对帮助基金会的志愿活动感兴趣，因此选动词assist的动名词形式(C)assisting。(A)expand表示“扩张”，(B)incorporate表示“合并，混合”，(D)celebrate表示“祝贺”。

【正确答案】 B

【答案解析】解析：根据上下文语义，此处表示“开始志愿服务前需要先接受指导”，故应选择表示“之前”含义的介词短语(B)prior to。如果选状语从句引导词或介词(A)except(除……之外)，句意不通。如果选状语从句引导词(C)even though(虽然)或者(D)whereas(然而)，也会使句意不通。

【正确答案】 A

【答案解析】解析：此处应选可以修饰名词phrases的词语，因此选organize的分词形式(A)organizing(组织)。名词(B)organizer只有在构成复合名词时才能修饰名词，动词(C)、(D)不能修饰名词。
