帮忙解决个英语语法知识点!

这句话不是主谓宾,也没有真正倒装.
为了叙述或描绘更加生动,将表示运动方向的副词（如“here,there,out,in,up,off,down,away,back,now,then等）放到句首.注意：这种句子必须是谓语动词为go,come,run,rush等表示位移的动词,主语是名词时,句子的主谓要倒装.
Here comes the bus.
公共汽车来了.
There goes the bell.
铃声响了.
Down came the rain.
雨落了下来.
Out rushed a tiger from the wood.
忽然从林子里冲出一只老虎.
Now comes your turn.
现在轮到你了.
Then came the order to take off.
起飞的命令到了.
主语为人称代词时,不用倒装.如：
There he comes.
Here they are.
Here it is.
