小学一年级英语作文:Good friend

文中词汇表达稍欠丰富，但单词拼写做的很棒；若加强一些复杂句和从句的使用，文章会更棒；层次不清晰，几乎没有使用衔接词；请提高文章内敛性，段落和句子要围绕主题展开。

Dear Mr.Dmitri Zhogolev, About 6815060 of weight problems,I am deeply sorry for this problem . the hammer weight is 26.02kg, and not is 36.02kg.This is my job mistakes. I fully understand the meaning of your last.So i pledge that no next. The difference between the old weight (24.31 kg) and the new weight (36.02 kg) of a carton with 6815060 hammers is 48%! But a carton with 36 pcs. of 600 g hammers (36.02 kg) can't be heavier, than a carton with 36 pcs. of 800 g hammers (33.02 kg)!!!
