问题描述：
These shoes look very good.I wonder___
A how much cost they are B how much do they cost C how much they cost D how much are they cost.我搞不清楚BC的区别,希望明白的人给我讲明白些.
答
从句要使用陈述语序 所以选择C
答
B是用的疑问语序，而题干要填的是宾语从句，要用陈述语序，陈述语序中，不能含有助动词！故选C！
答
选C
首先得明白后面应该接的是宾语从句,因为I是主语,wonder是动词作谓语,后面就应该是宾语从句了.
而宾语从句中应该是引导词+句子,其实句子直接用陈述语序.
他们花了多少钱,应该翻译为how much they cost
A答案中are是多余的,因为cost可以直接做宾语,不需要再加BE动词了
B答案中不应该再加do,因为加了do,D答案就是个完整的句子,而不能作从句
D答案同A
建议楼主看看宾语从句的相关知识,就不会再搞不清楚了.
