(A).that for every dollar spent on controlled small-scale burning,forest thinning,and the training of fire-management personnel,it saves seven dollars that would not be spent on having to extinguish
(B).that for every dollar spent on controlled small-scale burning,forest thinning,and the training of fire-management personnel,seven dollars are saved that would have been spent on extinguishing
(C).that for every dollar spent on controlled small-scale burning,forest thinning,and the training of fire-management personnel saves seven dollars on not having to extinguish
(D).for every dollar spent on controlled small-scale burning,forest thinning,and the training of fire-management personnel,that it saves seven dollars on not having to extinguish
(E).for every dollar spent on controlled small-scale burning,forest thinning,and the training of fire-management personnel,that seven dollars are saved that would not have been spent on extinguishing
后面给的解释是，（1）having to wordy。有什么原因吗？（2）选项D.E中，that it saves seven dollars 和that seven dollars 中的that让句子分裂，请问是什么语法知识？谢谢作者: fxxxfxxx 时间: 2017-5-27 09:59
这里你觉得having to有什么作用吗， 不管怎样都是很awkward的吧？而且其他几个选项都有很多问题，不只是have to extinguish
