参考范文：
As society and economy develop, dishonesty is no longer a stranger to us. Manufacturers and businessmen may promise more than their products can guarantee so as to make more profit. Doctors and nurses may lie to their patients for their patients’ benefit. Students may cheat on exams for better scores. As a matter of fact, dishonesty has become so widespread that wherever you are you find cases of dishonesty.
However, it is honesty that brings benefit both to yourself and to others. By being honest, manufacturers and businessmen build up mutual trust between themselves and customers, which in the long run generates more profit. By telling patients the truth about their conditions so that they can make their own decisions, doctors and nurses enhance their own credibility and honor their profession. By giving honest answers to questions, not only can students themselves learn about their own strengths and weaknesses, but they help their teachers evaluate the quality of their instruction as well. Therefore, it pays to be honest and everybody must learn to be honest.
