不清楚“然而圆规很不平，……”中的“圆规”究竟是借喻还是借代，也会明白“圆规”指杨二嫂，不影响对这个句子基本意思的理解。但若不了解一定的句子结构，哪怕你每一个单词都认识，也可能不懂其义。这是因为语言知识对学生理解母语一般不会构成障碍，而对理解外语往往会形 It is unclear whether “compromise is very uneven,” and whether the “compass” in the “...” is a metaphor or a substitute. It will also be understood that “compound” means Yang Eryi and does not affect the understanding of the basic meaning of this sentence. However, if you do not understand a certain sentence structure, even if you know each word, you may not understand it. This is because linguistic knowledge does not usually pose an obstacle to students’ understanding of their native language, but it tends to shape the understanding of foreign languages.
