懂英语的请来指教一下,
"I am thought that loneliness is a wonderful enjoyment,but now I hesitated it.I have alone for a long time.Once there was a girl in the feast when greeting to my hair message,but now there isn't.I think it must be my apthy let her loer the patience.But does she know that I had put her as my ideal.She is the source of my happinesr,and also my miserable."以上这段话是我自己写的,我想知道我的用词与语法那里有错和不妥.请来者有点责任心,不要瞎指点,
Once那句对吗?最后一个为什么不用miserable的名词是misery?
