【参考答案】

1.【答案】D

【解析】：考查短语辨析。句意：根据《无线电通讯名录》的记载，目前有16376家获许可的无线电台正在广播。A. Due to 由于；B. Taken by 被……吸引；C. Required by 被……要求；D. According to 根据。只有D选项符合题意，故选D。

2.【答案】B

【解析】：考查动词时态。句意：科利博士拥有人类学的博士学位，并且在去年十月份他出了一本关于尼罗河三角洲的书。由句中的last October可以判断时态是过去式，所以选B。

3.【答案】B

【解析】：考查词性辨析。此处空格中的单词与and 后的chief executive 并列，故只能选B。foundation 虽为名词，但意为"建立"，不符合语境，故可排除。

4.【答案】C

【解析】：考查副词词义辨析。句意：周三晚上9:30到10:00之间电子邮件服务器会被暂时卸下，这样我们就能更新软件了。A. permanently 永久地；B. immediately 立刻，马上；C. temporarily 暂时地；D. successfully 成功地。根据题干中的时间段between 9:30 and 10:00 p.m可以推断，服务器是被暂时卸下而不是永久卸下，所以A选项不正确，B和D选项与题意不符，故选C。

5.【答案】B

【解析】：考查固定搭配。句意：不幸的是，纽约办公室在上三个季度都没能达到销售目标。本题考查fail与动词的搭配，fail to do 是固定用法，表示失败或未做成某事，故正确答案为B。
