这道题的时态为一般过去时,从was astonished可以看出
所以选项里的动词也应该是一般过去时
cost的过去时为原型cost 所以不需要用第三人称单数

这里是一般过去时，cost的过去式与原形一样

时态是一般过去式,考察cost的过去式.

cost 是过去式

cost是过去式，cost的过去式和原型一样

这是个宾语从句，遵循主从句时态一致原则 因为主句 谓语动词was是过去式 所以从句的谓语也用过去式 cost 过去式是cost 所以就不存在你说的costs 这种单三形式了

原形cost 过去式cost 过去分词costed
这里的主句是过去时态，所以从句也用过去时态
如果 She is astonished to see that the computer____eight thousand yuan。这样的话用costs
