is this room___has the most beautiful wallpaper

问题描述:

is this room___has the most beautiful wallpaper
为什么用the one that 不用 which

这个句子中有个小埋伏.
其主语是this room ,而不是this,如果把其还原成陈述句一看你就明白:
This room is the one that has the most beautiful wallpaper.
而不是This is room hase the most.
我刚才答过一道 类似的题,请看参考!
不明白再问.
