【正确答案】 C

【答案解析】[考点] 词义和用法
[解析] A项用法不正确，不能用to promote someone to do something的句型；B项与原句表述正相反；C和D都有“影响”的意思，其区别在于affect通常引起负面的后果，而influence经常引起正面的结果。

【正确答案】 B

【答案解析】[考点] 介词
[解析] 本题的选择与前后的用词都有关系，前面是question，后面是the product or service，中间的介词只能用about(关于)，意思是“就有关产品或服务请教任何问题”，其他介词在这里语意讲不通。

【正确答案】 C

【答案解析】[考点] 逻辑连贯
[解析] 由此，最关键的是要判断空白前后两句话之间的逻辑关系。两句之间应该是较为明显的并列关系，所以应该用or。而A项的因果关系、B项的时间关系和D项的转折关系在逻辑上都讲不通。

【正确答案】 A

【答案解析】[考点] 介词词组

【正确答案】 A

【答案解析】[考点] 动词词组
