各位童鞋们，以下是大全注释的解释：前面one that they believe is , 正常顺序they believe that one is...变成one+that定语从句, 因为one不作主语，所以一般省that, 后面believe +that宾语从句,在定语从句中出现的宾语从句，that一般也省，所以应该是one they believe is，不过这里believe宾语从句不如believe to do好。 但是我不太理解前辈的解释。第一one+that在one不做主语的情况下that要省略？为什么啊？第二one that they believe is这个结构中that是做什么成分啊，不是they believe的宾语么？怎么注释里解释说这个that 引导的是one的定语从句，然后they believe之后的that作为宾语要省略呢？
首先我要非常感激你回答我的问题，03年的ID都是CD的老前辈了。 其次我说一下我的理解，麻烦指点指点：one they believe that is.....这个句子中，one后面有一个that引导的定语从句，但是that是做宾语，所以要省去。然后这个believe后面又是一个that引导的宾语从句，that不可省。我是这样理解的。 虚心求指教。
我碰到这种类似的什么中间有“sb agrees”成份的就直接当成插入语不看跳过，这样做题还没错过。OG12里面也有一道这种题就可以直接这样做......如果把那个they believe当成插入语的话，后面的定语从句就只是一个巨简单的one that （they believe）is....

哦，对的，经你一点拨我想起来了，在Prep语法笔记上有写，叫做嵌入式关系分局，对的对的。OG的题这个，谢谢你啦，我懂了。 OG12-118. The world wildlife fund has declared that global warming, a phenomenon most scientsts agree to be caused by human begings in burning fossil fuels, will create havoc among migratory birds by altering the enviroment in ways harmful to their habitats.
