知识不足的英文

I find what I have acquired can not deal with the problems I have met with in my work.

楼上明显用LINGOES翻译的。搂主也没有明确啥文。英文？日文？德文？....

"This document is really work in progress and I am sure much remains to be improved."

一般情况下，不足，欠缺的英文翻译可以是：not enough(形容词，作表语), insufficient（形容词，作表语、定语）, shortage(名词，作主语)，lack（名词或动词，作主语或谓语）。 如果意思是不够完美的话，可以用imperfect (形容词，作表语或定语) ，或者用词组need to be improved, need improving也可以。比如说，我们的生活水平还有待提高：Our living standard needs to be improved.
