1, geographical reasons.

The formation of culture is closely related to the local environment and deeply influenced by it. In English and Chinese, the cultural differences of many animal words are caused by different geographical environments. For example, people living in mountainous areas will use more words from mountainous areas to express the meaning of words, while people living in tropical areas are more words and connotations of tropical fruits. At the same time, the regional environment is different, living habits, eating conditions and so on. They are all different and convey different meanings.

2. Historical reasons.

Every country has its own different history and culture, including poems, fables, legends, biographies and so on. Among them, the most important thing is that it implies this form and embodies the national characteristics at that time. These cultural connotations are important manifestations of human cultural relics, which are helpful for future generations to understand and learn history.

The study of historical and cultural background will help us to understand the cultural differences between English and Chinese. Every nation has experienced historical changes from generation to generation, and the cultural connotation and significance of some things passed down from each era have changed, increased, decreased or even completely eliminated. These meanings are of great reference value to later literary phenomena and learning.
