英语翻译
He could only speculate that he had so successfully conditioned the rats that saccharin alone now served to weaken their immune systems enough to kill them.
求翻译,顺便求句子结构分析

他只能推测,他已经顺利解决了那个,关于老鼠糖精单独存在能削弱他们的免疫系统以杀死他们（老鼠）.
这句话主要需要搞清楚he和them所指代的内容,另外看一下that引导的从句
再问： enough to kill them 是跟在那个部分后面的？句子的层次看不太明白
再答： weaken their immune systems。就是说削弱免疫系统，以杀死他们。首先是削弱免疫系统，削弱到一定程度以达到杀死的目的。
