The teacher pretended that algebra was a perfectly natural affair, to be taken for granted, whereas I didn't even know what numbers were. Mathematics classes became sheer terror and torture to me. I was so intimidated by my incomprehension that I did not dare to ask any questions.
老师声称代数是完美而自然的、我们应无条件地接受它，而我甚至不能理解什么是数。对我来说数学课完全就是恐怖和折磨。我完全不理解代数，这使我胆怯得不敢问任何问题。
The end of life is happiness， and happiness is tranquility.
