1.D
【句意】随着中国汽车工业的快速发展，一种新颖的胎面胶SIBR已表现出一种广阔的市场前景。
【解析】形容词词义辨析。impressive“给人印象深刻的；感人的；可观的”；comprehensive“广泛的；综合的；全面的”；intensive“加强的；[农]精耕细作的”；extensive“广阔的；广大的”。由关键词“market prospect市场前景”的对应知“广阔的”符合语境，故D项正确。

2.D
【句意】在金融学中，机会成本分析指的是与预期投资回报相比在其他投资中可能取得的投资回报。
【解析】语法结构——分词做状语。分析题干结构可知“______ the expected investment return”这部分在原句中充当状语成分，由于其逻辑主语是the amount，故需要用表示被动的过去分词；再由compare表示“与……相比”需与介词with搭配知D项“compared with”正确。
