By browsing this Web site, those involved in teaching and training, __on the academic or professional side, will find many useful reference sites.
(A) if (B) but （C) whether (D) even
请说明清楚理由，搞不清理由的人士就不要答题了，谢谢配合哦。答的好有分送。
答：C
译：通过浏览这个网址，那些从事教学和培训工作的人,(不论这教学和培训是与学术还是专业相关），都将找到很多有用的参考网址。
析： 此题考查连词的用法。这四个选项中，其它三个都可以作连词用，只有even是异类，只能作副词用。引导宾语从句时，常用if代替whether,所以AC互为干扰项。这时从编题规则来思考问题的方法。当然，关键还是句子意思的理解，生活逻辑的判断，再加上语法习惯，语言的结构。这里的on和or两词也是关键。
这句话的语境，似乎是一个广告，在介绍一个网站。这很有可能是一个与教学相关的向导网站，主要的意思是说，“通过浏览这个网站，从事与教学培训相关工作的人就能够找到很多有用的参考网站。
