This word is from a story about the U.S. government gathering telephone and Internet records:
这个词取自一个新闻报道，该报道与美国政府收集电话和网络记录有关：
The basic questions are these: Is the surveillance relevant to a terrorist investigation?
最根本的问题是：这种监视是否和调查恐怖分子有关？
And does the government monitor actual conversations and emails or just look at who’s involved?
政府真的是在监视对话和邮件，还是仅仅查看了相关人员的？
“Investigation” means to examine something closely and carefully.
“调查”的意思是详尽而仔细的检查某一事物。

In this story, the government is directing the investigation to find terrorists.
在该报道中，政府正在进行调查，意在发现恐怖分子，
