如何識別“假”反意疑問句

有些結構看似反意疑問句，但其實不是，請看以下兩例：

I think he will win, don’t you? 我認為他會贏，你說呢？

I think its price will go up, don’t you? 我認為它的價格會上升，你認為呢？

以上兩句反意疑問句中的don’t you 為don’t you think so 之省略。

請再看兩例反意疑問句：

Many people have read the book, have you? 許多人都讀過這本書，你讀過嗎？

Some students are interested in football, are you? 有些學生對足球感興趣，你呢？

第一句中的 have you 為 have you read it 之省略，第二句中的 are you 為 are you interested in football 之省略。
