train用于主动语态与被动语态的区别

问题描述

His parents won't allow him to train so much.

请问这里的 train 是不及物动词表示“接受训练”，对吗？

但这里用被动形式的 to be trained 可以吗？train 作及物不及物时怎样区分呢？

（这有时关系到是用主动语态还是被动语态的问题）

老师答疑

陈老师：

train 表示类似“训练”的意思时，可以是及物动词，也可以是不及物动词，所以如果语义需要，用主动语态和被动语态都是可能的，但两者意有所不同：
▲主动语态：Sb trains. 指某人主动或自主训练。如：
The trainer observed the players as they trained on the field. 运动员在操场上练习时，教练员仔细地观察着他们。
She trained hard for the race, sometimes running as much as 60 milesa week. 为了比赛，他拼命地训练，有时一个星期要跑60英里。
▲被动语态：Sb is trained. 指某人被训练或接受训练。如：
Soldiers are trained to obey orders. 军人受过训练要服从命令。
The dogs had been trained to jump through hoops. 这些狗受过跳圈训练。
I have an uncle who has been trained to be a pilot. 我有个叔叔接受过飞行员培训。
▲你的句子：His parents won't allow him totrain so much. 若将 to train 改为 to be trained 也可以，但意思有所变化：
His parents won’t allow him to train so much. 他的父母不让他那样刻苦地训练。（指自主自发地训练）
His parents won’t allow him to be trained so much. 他的父母不让他接受那样艰苦的训练。（指被动地接受训练）
