Question

也许这一切只是我的猜测 英语怎么翻译？

Answer 1

Maybe all of these were my suspicion.

1.这一切肯定不只一种想法。所以我用了these。
2.正因为是猜测，所以不能虚拟的were。
3.guess是推测的意思，有一定逻辑和道理，如果你说的是一种怀疑心理，用suspicion吧。

Answer 2

Maybe that's all myself's imagination.

Answer 3

标准翻译：
Perhaps all of this is my guess!
或者
Maybe everything is my guess!
