1.In the room（could only be found a table）with three legs and a few broken chairs.这句话的谓语是could be found,这句话强调地点状语,所以句子倒装.陈述语序是A table with three legs and a few broken chairs could only be found in the room.
2.In the corner of the room(was a small round wooden table).也是强调状语的倒装句.形容词的顺序在英语中是有规则的,不能乱排.我曾经背过以个口诀希望可以帮到你：“限定描绘大长高；形状年龄和新老；颜色国籍出材料：作用类别往后靠.”small 表示“大小”的形容词(小的),round表示“长高”的形容词（圆的）,wooden表示“材料”形容词（木质的）.所以按照口诀的顺序答案就出现了~
3.第三题的陈述语序是The rocket shot up into the air when the ten second countdown was over.这里shoot是不及物动词,没有被动语态.
