This was built out into the sea.这是个被动语态的句子,可build是及物动词啊,为什么后

1。因为及物动词可以先加宾语,然后再加上一个副词啊。2。这样的例子太多了,如give sb up,pick sth up,take sth out。3。举个具体的例子：I took my hand out of my pocket。变成被动：My hand was taken out of my pocket。4。再看你这个句子,加个名词进去以更好理The workers built this tunnel(海底隧道) out into the sea。变成被动:This (tunnel) was built out into the sea。
