这里如果选D的话，failure to advise as prominently the highest price.. as the lowest 是不是会变成和原来的意思相反呢？读着怎么那么便扭
请NN指点 "读着怎么那么便扭" - 你的感觉是对的.
failure to advertise as prominently the highest price in a range of prices for a service or product as the lowest =>failure to advertise prominently the highest price 把副词prominently 放到宾语the highest price 前面来了. 当然有反例, 但 副词一般在宾语后面比较舒服, failure to advertise the highest price prominently.
再看: I study GMAT hard. I eat apple fast. 换个位: I study hard GMAT. I eat fast apple. - 便扭 |
