-------我竟然还不如你一个刚认识的朋友来的重要。-------------
朋友,你的句子非常完美,但在英语中需要一定的语境。比如说:
It is unthinkable that I should be less important (to her,) than you , a newcomer / a new acquaintance.
(汉语与英语不是一个概念,希望你能理解。新年快乐。)
I even not as important as your friend who are known just a moment ago.
i can't believe in your mind, i'm not important as a new friend for you.
!To my surprise,i should be less important than a casual acquaintance you have just made。
I'm even less important than the friend whom you just knew.
My unexpectedly still not equal to your a just- known friend come of importance.
