______room is on the 5th floor
问题描述：
______room is on the 5th floor
A Tom and Bob B Tom and Bob’s C Tom‘s and Bob D Tom‘s and Bob‘s
答
B 是正确的.
room 用了单数形式,而且后面是is,说明房间是两人共有的.
如果是两人各自的房间,应该说Tom's and Bob's rooms.
希望能帮到你,祝你进步.哦哦 那如果是______room are on the 5th floor呢选什麼啊 谢谢room 应该用复数，因为后面是are ______rooms are on the 5th floor.这时应该选D.
