Characteristics of science and engineering majors are considered to be inferior in system, wide in knowledge, and abstract in concepts. It is a wide-spread reality that the students’ English is quite poor. We studied on the bilingual teaching from several aspects including course selection, text book selection, and teaching mode. To qualify the bilingual teaching, we should keep a principle that “the target is the guide, the teacher is the lead, and the student is the subject”. Flexible teaching should be carried out on the basis of improving the quality of teachers and selecting appropriate teaching materials. In practice, it is important to take a progressive bilingual teaching mode and adopt diversiform teaching means.
