【答案解析】{{B}}My Opinion on Keeping One's Word{{/B}} Keeping one's word is a rare quality that man can possess. Because the basic character of the world is changing. When things have changed, is it possible that a person can still keep his word? The answer is "Yes" ,but it demands a lot on the part of the person. Do you have the experience that you promised to do something for others, but when the moment really came, it turned out that if you did it, you would have to sacrifice a lot yourself. For example, parents may promise to go on a travel if their child could get a satisfactory mark in the examination. But when the child comes home with the satisfactory mark, they are engaged in their work so that they can't leave within weeks. How to make the decision? If the parents give up the travel, the child will feel hurt; but ff the parents keep their word, the work will be interrupted, which is forbidden by the boss. Anyway, they have to suffer in a sense. In a word, I think we should try to avoid promising anything if it is possible. And if you have promised, try to keep it at all expenses.
