First, because most of today's advanced theories and technologies come from abroad, it forces China to go abroad and absorb advanced science and technology. Young intellectuals are the backbone of the country, and young students must improve their foreign language level. Bilingual teaching has become a very useful teaching form to promote students' integration with the international community.

Second, China is constantly developing. In order to inherit China culture, teenagers must master the necessary foreign languages so as to carry forward China culture in the future.

Third, many domestic textbooks are far inferior to foreign textbooks, and the translated textbooks often miss the original information, making it difficult to grasp the logical relationship. Using English textbooks can help students master the logical thinking of foreigners in advance, which is very useful for reading and writing papers in the process of scientific research.
