——The price of this bike is _____.You can buy one.——But I still don't have enough money.A.expensive B.high C.cheap D.low

选D 如果没有price 选C
因为价格用高低形容

选D，首先联系下文的but可知这里填的意思是低，排除A、B；这里不选cheap的原因是，cheap一般修饰的是物品，比如：
Her neck was bedaubed with cheap necklace。但是这里修饰的是the price ，所以要用low。

价格通常用便宜或昂贵来形容， 后面答句 说, you can buy one , 表明自行车的价钱不贵, 就是说便宜，所以用cheap 。
希望对您有帮助(*^__^*)

你好:
选 C 后面答句 说, you can buy one , 表明自行车的价钱不贵, 就是说便宜
所以用cheap

low 一般用于形容高度很低, 如: The white building is very low.

翻译: 这辆自行车的价格很便宜, 你可以买一辆.

希望对您有帮助!
