问题 This tour of the generating station is very interesting, which is the first opportunity I ______of seeing how electricity is produced.

选项 A、have
B、will have
C、have had
D、had

答案 C

解析本题考查在特定句型中的时态用法。本句句意为“这次的发电厂之行非常有趣，这是我第一次有机会看到怎么发电的”。在be the first opportunity／time／week／month…that…句型中，be动词用一般现在时，that从句中的谓语动词用现在完成时。所以答案为C)。
