learn sth（by) oneself中的不要什么时候by可省去请举例句

by oneself :这个往往在句子中作状语,可以将其省略句子还是通顺的.它强调的是方式,即：一个人、独自地oneself ：在句子中作同位语、宾语、表语等.只有作同位语时,可以省略如 the boy came to the shop himself .中的himself是同位语He isn't quite himself .他今天状态不好.中的himself不可以省略He enjoyed himself at the party.派对上,他玩得很开心.宾语,不可以省略 以上就为例句======以下答案可供参考======供参考答案1:by oneself在这是作状语，你也可以直接省略的。剩下oneself就是主语的同位语了。供参考答案2:一般来说 by 有澄清句子含义的作用，所以不宜省略。换句话说，用 teach oneself 代替 learn oneself 比较好。用英语解释吧：You taught yourself if you did not have a teacher but learnt through books, internet, etc. It means the same thing as you are self-taught.You learnt by yourself can mean exactly the same thing, but could also mean that you were the teacher's only pupil.
