Each has its own advantages. New Standard College English is an international textbook with pictures and texts, strong articles and novel questions, but it is more difficult to learn by yourself, because this book can only provide students with workbooks such as books, and there is no grammar course. New Horizon College English is widely used all over the country, with more exercises after class, closer to the exam and multiple choice questions. And you can find many tutorials in the bookstore. But the textbooks look a little out of date.
