---Excuse me. Could you tell me ?
---＄328. You can get 20% off if you buy two.
A．how much the dress was
B．how much the dress costs
C．what is the price of the dress
D．how much I paid for the dress

请问为何选B？

Answer 1

首先，A和D显然不对（因为它们都用了过去时）。
其次，C不对。因为宾语从句应该是陈述语序，只有把is放在dress之后即what the price of the dress is才是正确的。
B是用how引导的宾语从句的正常语序，正确无误。
