Having taught English in an senior high school for 26 years, my teacher has developed the habit of trying to make his students to get good marks in exams. But some textbooks who include dozens of mistakes will have a seriously bad influence in students. Since he's found out over 30 real mistakes in your last 3 textbooks nothing, I firm believe that he can still find out other mistakes in your next textbook for free. Wishing us to use good textbooks than before, he's willing to proofread（校对）it before it was printed. Frankly spoken, my honest and responsible teacher has no intention of looking down upon you textbooks.
