we need to adjust the position of the drive变被动怎么变?the position of the drive is needed to ...

to be adjusted by us为什么不是:the position of the drive is needed to adjust by us呢?adjust为什么要变呢?有什么规律吗?主动变被动，动词要用过去分词，adjust的过去分词是adjusted是不是胃语的所有动词都要变被动;如 need 和adjustneed 可以不变，need是情态动词，带情态动词的句子变被动，只要后面的实意动词变成被动就可以了
