Some have claimed that major glacier-fed rivers changed their course, dramatically affecting the water supply and agriculture; or that the cities could not cope with an increasing population, they exhausted their resource base, the trading economy broke down or they succumbed to invasion and conflict; and yet others that climate change caused an environmental change that affected food and water provision.
我查了一下别的分析:这句话划分应该是some 是主语,have claimed 谓语,然后that引导宾语从句,or that,and yet others that 各自引导宾语从句,但是第二个分号,即第三个宾语从句里面的yet others是充当什么成分吗?others是代词,它能直接加在that前面吗?
请问老师,我对这句话的句子成分分析正确吗?and yet others that 属于什么成分吗?
