live ,when 用法
is this a good way for animals to live ?
zoos are terrible places for animals to live
i have never seen one like or one that was suitable for animals to live in
为什么有些地方有live in 有些只有live 还有,为啥where后面live也没in
turn off the lights when you leave the room
you should turn off the shower when washing your hair
为什么when后面有时候有ing,有时候没有?
顺便讲一下与while的关系
