train有被动语态么？

有的，前面加"be/is/am/are"再把"train"转成过去分词"trained"就是被动语态了

例如：
He was trained as a doctor but devoted his life to letters.
他学的是医但毕生从事文学。

Anti-tank weapons were trained upon all the possible approaches to the bridge.
反坦克武器对准了所有能够接近大桥的通道。

The examiner must be trained in the use of the test.
负责考试人员要经过培训。

有，只要是及物动词就有被动语态
train
[trein]
n.
火车, 列车, 行列, 后果, 顺序, 长队, 长袍(裙)拖地的部分, 导火线
vt.
训练, 培养, 瞄准, (园艺)整枝
vi.
锻炼

有，意思是受训

He was trained as a doctor．

他原来是学医的／是学医出生的。
