C．by ; to

D．by ; at

Answer 1

B

試題分析：考查介詞：第一空填to，be known to sb為…所熟知，第二空填for，have a good nose for對(duì)…嗅覺靈敏，句意：眾所周知，老鼠對(duì)奶酪嗅覺靈敏。選B。
點(diǎn)評(píng)：介詞一直是命題者常設(shè)置的考點(diǎn)和重點(diǎn)，平時(shí)要加強(qiáng)記憶。本題的四個(gè)選項(xiàng)都很重要，尤其要注意四個(gè)短語在具體語言環(huán)境中的使用，考生應(yīng)注意對(duì)介詞搭配的短語的正確歸類和對(duì)詞義的準(zhǔn)確理解。
