宾语从句要用的陈述语序是什么举个例子

就是主谓宾。

陈述语序就是和陈述句的顺序一样，主语在前，谓语动词在后。
例：正常语序问句：你来自哪里？Where are you from?
宾语从句：我想知道你来自哪里。I want to know where you are from.
where you are from 整个句子做know 的宾语，用陈述语序you are 而不用are you.
另外，宾语从句考点除了考虑陈述语序外，还要考虑主句和从句的时态。
这方面如有问题，请再问我。

例一：
Where do you come from?He asked Lucy.合并为一句：He asked Lucy where she comes from.
Where do you come from是疑问语序,where she comes from是陈述语序.
例二：
How old is Jim?She asked.合并为一句：She asked how old Jim was.
How old is Jim是疑问语序,how old Jim was是陈述语序.
例三：
Can you swim?She asked.合并为一句：She asked if/whether you could swim.
Can you swim是疑问语序,you could swim是陈述语序.
