oneself与by oneself的区别
例句：
after two years,my father told me and my brother that he felt we were old enough to cut the grass by ourselves.
after two years,my father told me and my brother that he felt we were old enough to cut the grass ourselves.
答案上只有第一句
第二句不对

优质解答

oneself 是某人自己
by oneself 是由某人自己
你的列句第一句：2年后,爸爸告诉我和哥哥他觉得我们足够年龄可以自己修剪草坪了
第二句其实也差不多,也是翻译成我们自己修剪草坪
英语翻译不要死板,主要根据内容来的
