英语难句,同位语丛句帮我拆分一下这句话,that后面为什么要加一个of,或者句中为什么会有一个that During this period,the area of research activity most closely connected with that of autonomous agents was AI planning 最
During this period,在这段时间里（时间状语）
the area of research activity 研究活动的领域（主语）
most closely connected with that of autonomous agents 与自治体领域联系最紧密的（后置定语,修饰主语）
was 是（谓语,系动词）
Al planning 阿尔计划（表语/宾语）
全句：这段时间,与自治体领域联系最紧密的研究领域是阿尔计划.
句中的 that of = the area of,that 是代词,指代 the area.英语修辞中为避免句子重复乏味,将与前面相同的名词以 that 替代.举个例子：
The population of China is larger than that of any other country.
中国人口比任何其它国家的人口都多.
句子 = The population of China is larger than the population of any other country.
