[求助]GWD1－23

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.

The most conspicuous fault in D results from the fact that the ununderscored part in the end of this sentence comprises an finite verb as one part of the coordinate predicates of a relative clause,  a part that is, " but do not denude the forest".  This finete verb wants a finite verb form in the other part of the coordinate predicates.

That is sure,

从句中的but结构，

which removes only selected trees, or surface fires that burn down individual trees but do not denude the forest.只有这里用that,后面才能用but

有点明白了，是因为but后面那个do（做题时为了赶时间没看到，可考试的时候迫于压力很有可能断章取义的哦），前面就要有一个verb与之对应吧，而burning是动名词，需要用that来引出一个动词，我理解的对吧？

可是bon gg的一句话我有些想不通哦，为什么前面有that后面才能有but啊？难道这是公理啊？

我的意思是that burn down individual trees but

                        do not denude the forest

这两个从句是平行的，如果意思相同，因为前头用that,那么就用and 或and that,因为这里的意思不同，所以用but

这是that 从句的情况，

如果是burning down individual trees ,那么后面也要用分词,就不会用到but了

所谓的“只有这里用that,后面才能用but”是这个意思

现在明白了，谢谢bon gg啊！厉害厉害

我也是在SC区学到的

MM多来看看，很有长进的（小声跟你说，特别要象tianwan学习，他的思路很那个那个）

嘻嘻，收到收到～

此外，LOGGING在这里表示伐木业，是个名词，就像marketing一样，所以和后面的surface fires相并列，这道题挺“坏“的。

是分词不是动名词，且现在分词在句末时（前面有逗号和主句分割），做伴随状语，或修饰的是主句谓语动词，表示伴随的动作；或修饰整个句子，表示伴随的结果。所以从这个意思上，也不能选C，因为remove 这个动作明显是logging发出的啊；burn也是fire的动作啊。

如果没有这两个逗号也没有后半句的并列成分限制，such work has not addressed either logging removing only selected trees or surface fires burning down individual trees，那又成了定语成分了，就要掂量是用定语从句好还是分词好了。
