王文的作文中,词和句子都用得恰当
病句中 作文 词 句子是并列关系,实际是在作文中的词和句子
所以修改如上

解题思路：因为20.78的最后一位数字错了，我们可以估计：正确的平均数应该在20.70--20.79之间．

如果平均数是20.70的话，那么这16个自然数的和就是20.70×16=331.2；如果平均数是20.79，那么这16个自然数的和就是20.79×16=332.64．所以16个数的和在331.2与332.64之间．
由于原来的16个数都是自然数，所以它们的总和是332．
答：这16个自然数的和是332．

点评：
本题考点： 平均数问题．

考点点评： 本题主要考查了实际问题-平均数问题．本题的关键是估计：正确的平均数应该在20.70--20.79之间．
