新概念英语第一册第26页，课文注释2中说，“在英文中不能用come upstairs to see it”。看到这里，我心生疑惑，于是上网搜索，在Answers网站上找到了关于 come upstairs and see it  和 come upstairs to see it 这两句的讲解。

    以下内容摘自Can you say 'Come upstairs and see it' or 'Come upstairs to see it'?：

    You can say either, depending on what you mean. Usually you are asking someone to perform a sequence of actions: first, to come upstairs, and second, to see something. The way to say this is "Come upstairs and see it." But if you are saying that the purpose of coming upstairs is in order to see something, in response perhaps to the question "Why should I come upstairs?" or "Where can I see it?" then "Come upstairs to see it" is correct.
