The vice-president and production director of the company _______ the welcoming ceremony held by the Capital Hill this evening.
A. is to attend
B. are to attend
C. were to attend
D. have attended
题目解答
答案
A. is to attend
解析
考查要点：本题主要考查主谓一致和动词时态的用法。
解题核心：
- 判断主语的单复数：需明确“vice-president”和“production director”是否指同一人。若为同一人，主语为单数；若为两人，则为主语复数。
- 选择恰当的动词形式：根据主语的单复数选择动词的单数或复数形式，并结合“this evening”判断动作的计划性，选择正确的时态（be to do表示计划或安排）。
主谓一致分析
主语为“the vice-president and production director of the company”。
- 关键点：当两个职位属于同一人时，主语视为单数。例如：“The president and CEO is attending the meeting.”
- 因此，本题中主语为单数，需用is搭配动词。
动词时态分析
- “this evening”表示动作尚未发生，且具有计划性，需用be to do结构（表示安排或预期）。
- 选项对比：
- A. is to attend（单数，计划性动作，符合题意）
- B. are to attend（复数，错误）
- C. were to attend（过去时态，与“this evening”矛盾）
- D. have attended（已完成动作，与“this evening”矛盾）
