Abstract: Bilingual teaching in engineering colleges is an important way to cultivate top compound talents with strong professional knowledge and proficiency in foreign languages. At present, there are problems in bilingual teaching of professional courses in engineering universities, such as uneven English proficiency among students, significant differences between original English textbooks and domestic textbooks, and weak teaching staff in bilingual teaching. Universities should improve the quality and effectiveness of bilingual teaching in professional courses by enhancing students’ English foundation and professional English proficiency, selecting appropriate bilingual textbooks, enhancing teachers’ bilingual teaching abilities, and implementing process assessments for bilingual teaching courses.
