第015句

One difficulty in translation lies in obtaining a concept match. By this is meant that a concept in one language is lost or changed in meaning in translation.

译文：翻译的困难之一在于获得相对应的概念，也就是说，在翻译过程中，一种语言中的某一概念的含义会丧失或改变。

点睛：名词difficulty常与介词in搭配，表示“…方面的困难”。句型By...is meant that...可以看成是What is meant by...？的变形，用于解释说明前文的内容。

考点归纳：和mean有关的常见句型还有：

*What do you mean by...？你怎么能做／说…？
