打电话的时候，订房间
I'd like to book a room. 我要订一间房。
I'd like to book a single room. 我要订一个单间。
I'd like to book a double room. 我要订一个双人间。
I'd like to book a twin room. 我要订一个双人间。
我们全部订满了。（好不容易找到心仪的酒店，最怕听到的一句话。）
We're fully booked.
现在有什么房间呢，此时此刻想到一个单词available
目前唯一的空房间就是双人房。
The only room available at the moment is a twin room.
