B./;bought

B./;bought
插入语do you think后面要用陈述语序,故A,C错。D时态不对

B 宾语从句

do you think为插入语,选C,只是一个一般的特殊疑问句 Where ( did) he (buy )the computer

你好。选择C。
他买电脑的动作只是普通的过去的动作,不影响现在。所以应该用一般过去式,did/buy。

B 从句用陈述语气,他应该是已经买了电脑,所以用过去时

b

B是正确答案

选B吧,因为do you think 是个插入语,后面应该是一个宾语从句,因此应该是陈述句式,动词不应该提前。而问他在哪买的电脑说明电脑已经买了,所以选择过去式bought。

选B
首先一眼看出C、D是错误的,然后根据上下文的意思,问句应该是一般过去时,所以选B

B./;bought
