he finished his homework _____.
he finished his homework _____.
A,on his own
B.by his own
C,in his own
D.at his own
为什么是选A啊?我觉得选B啊,介词应该怎么用啊.唉
on one's own. 固定短语，就好比do homework为固定短语翻译为“做作业”，而不是make homework
固定搭配：do something on one's own
A.on one's own是固定词组，某人自己做某事，记下来就好
do sth. on one's own
固定短语，同义词是do sth.by oneself 独立做某事
选A,no one's own=by oneself 意思为“独自一人”，希望可以帮到你
on one's own 固定搭配＝by oneslef
do sth. on one's own 独立地；独自地；主动地
等于by himself
希望能帮到你。
答案：he finished his homework on his own .
解析；on one'own 是固定搭配,翻译为由某人自己.

on one'own 是个固定短语，其含义=do sth by oneself,即靠自己/独立去做........的意思，在句子中常用作方式状语。
on one's own=do sth.by oneself=do sth alone
