格式问题：标点符号紧跟上一个单词，和下一个单词之间空一格。


When the Customs Officer saw a man go through the Green Channel ,the man said that he had nothing to declare.
这里用when不是很通顺，可以把when去掉，the man前加and连接句子

This made the Officer suspicious,so he was demanded to unlock the case.
这里不需要用被动语态，可以改成so he ordered the man to unlock the case

The case was too empty and when the Officer was going through ,he realized to his horror that the  Officer examined the carefully and saw the packet at the bottom of the case was full of someting.
这句话不够通顺，具体是要表达什么意思呢~

He took a few steps back and remove the bottom part of the case which contained hundreds of gold watches.
removed过去式

while the Officer looking at the packet .The man tried to run away.
句子首字母大写，两句中间用逗号连接，was looking进行时

For a moment,the man disappeared among the crowd ,but he was soon caught and placed under arrest.
for a moment一般和延续性动词连用，disappeared可以改成was not in sight

祝同学学习进步~
