by oneself可以直接用作表语吗(本句为by myself)

by myself可以如此用吗？

Whenever I think about you，you are always by myself. 无论何时我想你，你一直在我身边。

Whenever I think about you, you are always by myself.

【答】我觉得，by myself 这个词组本身有误，应改为：by me。反身代词应跟句子主语一致，不然用宾格代词。这句话的主语是 you，不是 I。 建议改为：

Whenever I think about you, you are always by me.

【翻译】每当我想起你，感觉你总在我身边。

“系动词be + 介词短语”，非常容易见到的使用方法。本句的are 是stand, stay的意思。若换成实意动词stand或stay，always则放在前面。比如：

Whenever I think about you, you always stand/stay by me.
