问题 It is based on technology that already exists-—it’s not a pie in the sky prediction. The underlined part means______.

选项 A、unrealistic
B、marvelous
C、objective
D、pessimistic

答案 A

解析 习语理解题。原句中pie in the sky意为“不能保证实现的诺言;渺茫的希望”,而unrealistic意为“不切实际的;不现实的”,符合句意,故[A]为答案。marvelous意为“了不起的;非凡的;令人惊异的”;objective意为“客观的;目标的”;pessimistic意为“悲观的,厌世的;悲观主义的”。
