apprentice(ship)
1.apprentice（学徒）和apprenticeship后面都接to。如an apprentice to a carpenter和his apprenticeship to a carpenter。可以说his apprenticeship to journalism。
2.bind...apprentice to...（使…做…的学徒）是习语，总是用apprentice不用apprentices，如He was bound apprentice to a carpenter和They were bound apprentice（不用apprentices）to a carpenter。
3.apprentice（及物动词）后面接to，作bind...apprentice to...解。例如：He was apprenticed to a carpenter.
