D解析本題考查與價錢連用的介詞的用法。value在本句中是動詞，“估價”，后常用value +名詞+at+具體多少錢，表示“估計某物值（多少錢）”，此時at表示價格、數(shù)量、速度等；后面“花（多少錢）買下某物”，既可用buy sth. at，也可用buy sth. for。思路拓展:①for表示交換的概念，如：I gave him a record for his stamp. How much did you pay for the bag? I bought this set of coffee cups for $ 20.②常用at a high/low price來表示“以高/低價”。
