新概念1 13课课文注释说 Come upstairs to see it.是错的 哪里错了? come upstairs to see it 为什么不对? 新概念第一册第13课,Come upstairs and see it.能不能替换其中的see为look at,使整个句 come upstairs and see it 与come upstairs to see it 那句对 come upstairs and see me为什么不能用come upstairs to see it come upstairs and （ ）it 我填的是see 但答案是look at 我记得新概念用的好像也是see come upstairs and see it 为什么用and 不用to come upstairs and see it为什么and不能换成to 为什么come upstairs and see it 在英语中不能用come upstairs to see it.求 come upstairs and see it的反意疑问句 it come and see upstairs用所给词的适当形式组成句子（是疑问句）快! Come upstairs and see it把And换成To讲得通吗
