I WONDER HOW MUCH A.DOES HE SPEND ON HIS CAR B.DID HE SPEND ON HIS CARE C.HE SPEND ON...I WONDER HOW MUCH A.DOES HE SPEND ON HIS CAR B.DID HE SPEND ON HIS CARE C.HE SPEND ON HIS CAR D.HE SPEND IN HIS CAR 拜托附加why

选C,宾语从句用陈述语序，选C

选C
首先I （主语）wonder （谓语）how much... ...(句子做宾语，为宾语从句），用陈述语气；
然后spend on 是固定短语 在... ...方面花费 的意思
eg：I wonder how much these shoes cost.
我不知道这些鞋子多少钱。

C

这些选项都不对
I wonder how much he spent on his car
首先因为i wonder打头，所以用正常语序
然后因为车已经买了，所以要用过去时

C（如果不考虑时态问题）
这句是宾语从句,宾语从句从句要用陈述语气A B排除
spend sth on sth
spend sth (in)doing sth
这句后面接car,所以选C

感觉都不对。实在要选就选 B 吧。，spend on 为固定搭配，排除 D 。应该是过去时的，而且应该是陈述句，现在选项只有B稍对了。
