说明
祈使句之后的附加疑问句
核心问题
Open a window, would you? 我记得, 当主句为肯定句时, 附加疑问句应为否定句, 反之亦然。在上面的句子里, 主句为肯定句, 附加疑问句也为肯定句。这是怎么回事呢?
词典解答
当主句为祈使句时，后面的 will you? won't you? would you? could you? can you? can't you? 只是表示“请”的意思，使语气变得客气一些，并不是真正的附加疑问句，因此常常不遵守附加疑问句的使用规则。但是，请记住一点：在祈使句为否定句时，后面一般使用 will you? 或 can you?（参见...will you? / won't you? / can you?）。
