原题如上，comma+ing做伴随状语是要有因果关系或者是同时发生的两件事，总之要有一定的逻辑关系。
那上题中答案covering和is ***lake也是属于同时的关系吗 还是说这不是伴随状语呢？ 作者: Fiona09 时间: 2016-9-23 15:51
是伴随状语呢，伴随状语所表达的动作或状态是伴随着句子谓语动词的动作而发生或存在的，题干就是说的两者同时存在的这个关系。作者: emmahiggins09 时间: 2016-9-23 23:18
这里主句是系表结构，commas ving 表示进一步补充说明，不是伴随状态。作者: VincentFSJ 时间: 2016-9-24 19:28
，doing这个东西可以修饰主句的主语那么相当于定语，以及整个主谓相当于伴随状语，或者doing是making/causing这些相当于结果状语，不过都一样就是就是这个状态和前面的动作有着密切的关系。如果是那个谁写信那个就是两个意思（letter，having。。。，outnumbering 这个题的a还是e选项），就是无关的东西。
