这里walking是现在分词做伴随状语吗?用现在分词做伴随状语需要什么条件吗?而且补全时为什么要用you are 而不是 you were
答
这是虚拟语气 当你去遛狗的时候 如果你不小心 就会被撞 因此 前面是are 但因为是虚拟 后面用过去时态 因为这只是假设 并没有真正发生
补全后：While you are walking the dog,(if) you were careless and it got loose and was hit by a car.
答
补全是you were 跟后面的时态要一致
答
是由一个主语发出两个动作或同一个主语处于两种状态,或同一个主语发出一个动作时又伴随有某一种状态.伴随状语的逻辑主语一般情况下必须是全句的主语,伴随状语与谓语动词所表示的动作或状态是同时发生的.所以补全是you were.
