在这个世界上也许我总是孤单的吧？翻译成英语~！谁能帮下忙~！

In this world, perhaps I always lonely bar.这绝对不正确啦！
Maybe I am always longly in the World? 这是别人给我的。这一句也有很多问题啊！ longly 拼错了，这是肯定句不应该用问号啊！
alone "单独的,独自,仅"其"孤独"之意一般不表示内心的孤独；lonely表示内心’孤独的，寂寞的”感情色彩浓重。你要翻译的这句话应该用lonely比较好些。
Perhaps in this world, I am always lonely.perhaps后面加 in this world似乎不妥。
Perhaps I am always lonely in this world. 这句应该是正确的。而且比较好吧！

In this world, perhaps I always alone
这个确实是对的！以上几种说法也对！用哪一个都可以过关！就大胆的用吧！

May be in this world i'm always alone.

肯定正确！！！：）

I may be always alone in this world.

Perhaps I am always lonely in this world.

你找的是错的，和一楼一摸一样，机器翻译的吧，语法都不对．

Perhaps I am always alone in the world
