选择问句的选择部分可能是完整的句子。例如，我现在需要某个东西，是我去超市买呢，还是汤姆从家里带一个？这样的选择问句就不省略成分：Should I buy it in the supermarket or would Tom bring one with him from home?

当我们把这个选择问句用作名词性从句时，我们用whether引导这个选择问句，同时问句改用正常语序，去掉问号。例如：

I asked her whether I should buy it in the supermarket or whether Tom would bring one with him from home.

第二个whether可以用if代替，也可以省略：

I asked her whether I should buy it in the supermarket or if Tom would bring one with him from home.

I asked her whether I should buy it in the supermarket or Tom would bring one with him from home.

在口语中，有时说话人先想到一个一般问句，然后又补充了一个备选的问句，则直接用问句形式表达这个备选问句，二个问句之间在说话时有停顿（思考过程），文字记录中就有一个逗号表示这个停顿。or后的问句用倒装语序实际属于口语中的口误，忘记了自己说的其实是间接问句。

I asked her whether I should buy it in the supermarket， or would Tom bring one with him from home.

我认为网友的句子就属于最后这种情况。or前有逗号，or后面补充了一个选项，忘记了这是间接问句而采用了倒装语序。

以下为COCA语料库例句，上述四种情况实际都可能出现。

One of the most interesting ideas was that they had a way of separating the chores and money aspect. You know, the perpetual debate over whether allowance should be tied to doing chores or whether members of a family should just do their chores and allowance should be independent of that.

Of course there's confusion, misdirected emotions, ambiguity over whether you like someone or they like you.

I once had a debate over whether we can blame religion for the actions of religious adherents -- or is it just being abused by dangerous individuals who deserve the real blame.
