Q23:

Past assessments of the Brazilian rain forest have used satellite images to tally deforested areas, where farmers and ranchers have clear-cut and burned all the trees, but such work has not addressed either logging,which is the removal of only selected trees, as well as surface fires, burning down individual trees but do not denude the forest.

• which is the removal of only selected trees, as well as surface fires, burning
  
• which removes only selected trees, or surface fires that burn
  
• which removes only selected trees, along with surface fires that burn
  
• removing only selected trees, or surface fires, burning
  
• removing only selected trees, as well as surface fires that burn
  
  

答案是B,   我选D, 看了讲解 说burning与denude不平行 这个平行怎么讲呢？but前后也要平行吗？   请NN指点,谢谢

haiyueqinhui

逗号隔开现在分词与前句的时候，现在分词修饰前面一整句句子，而buring应该修饰surface fires，所以修饰不当

haiyueqinhui

but的确需要前后有结构平行，这里是ing与动词一般现在时，错
而且but之后也不能跟现在分词形式，前句Ing,错

我的理解是这个样子的
1.but such work has not addressed either logging or surface fires that burn down individual trees but do not denude the forest.
首先logging与surface fires 平行，which 指代logging（n.）
2.surface fires that burn down individual trees but do not denude the forest.
burn down 与denude平行，主语surface fires~
