In my opinion, it is a good idea to do so, for it can not only help the smokers to smoke less, and it can also do good to other customers’health. Since you had given up selling cigarettes, the customers don’t like smoking are sure to support you. In addition, smoke in the shopping center may cause fire, which is very dangerous to both your possession and the safety of the customers. In a word, the non-smoking supermarket will not effect your business. To the contrary, it will help you attract more customers who want to keep health.Best wishes!Proofreading 21It has been years since the Chinese get plastic bags from supermarkets for free. China has banned free plastic bags at shops and supermarkets, but people have to pay for them.

So the Chinese is encouraged to take their own bags for shopping. Then what kind of shopping bag is the best to carry? Some student in Chongqing have a extraordinary idea.

From then on, I learned to help others and turn to my friends for the help whenever I had difficulty finish a task on my own. Surely cooperation made a great difference. Now I am getting well with my friends.My experience has teach me that only if we attach great importance with cooperation can we go beyond ourselves. As the saying go, “United we stand; divided we fail.”Proofreading 23Dear Tom,How is everything going recently? That has been a long time since we meet in China last time.

考试做题要求:1、在/**********found**********/的下一行改正错误。

2、将题目做完之后一定要保存。

3、不能删除/**********found**********/,也不能多行或少行。

1:数列中,第一项值为3, 后一项都比前一项的值增5;给定程序MODI1.C中函数fun的功能是: 计算前n(4<n<50)项的累加和;每累加一次把被4除后余2的当前累加值放入数组中, 符合此条件的累加值的个数作为函数值返回主函数。

例如, 当n的值为20时,该数列为3,8,13,18,23,28,……,93,98。

符合此条件的累加值应为42,126,366,570,1010。
