The key is definitely C! 习惯表达方式: sb. charge (sb.) the price for sth -- the price 是宾语, 第二个sb 是间接宾语 所以就有 The dealer's cost, or invoice price, is the price that the manufacturer charges the dealer for the car. the price = $10 之类 具体到此题, 就是 the price that the drug’s maker charges for another product with the same active ingredient. 如果选D, 从句的意思就变成 the drug's maker charges sth for another product 而不是 the drug's maker charges the price for another product see? |
