Honesty means speaking the truth and being fair and upright in act. Considered a virtue, it is admired in every country and every culture. He who lives and cheats is dishonest. Dishonesty is generally looked upon as an evil, and is despised and condemned by everyone.(当今社会上存在许多不诚实的现象。) However, there are people who try to get benefits by dishonest means. For example, some students copy the exercise done by others or cheat on examinations, in order to get good marks. The same thing may be said of a merchant who tries to get rich by deceiving customers. Those people may succeed for a time, but sooner or later, they will bring them nothing but troubles.（诚实利人利己，做人应该诚实。）As the English proverb goes, honesty is the best policy.

For another, if you want to succeed in your work, the first qualification you should have is honesty. Therefore, whatever your aim is, you must work honestly to attain it.1 分析优点缺点Positive and Negative Aspects of Sports1.参加体育运动的好处。2.但也有副作用。3.你的体会。The Two-Day Weekend1. 双休日给大学生带来的好处。2双休日可能给大学生到来的问题。3我应当怎样过好双休日。Advantages and Disadvantages of Having Part-time JobAt present, more and more university students are doing part-time jobs.
