prep1里面的一道题，貌似1里面遇到两次，答案第一次选的是D，第二次变成A了，我想请问各位大牛，这题应该选什么。。。个人感觉选D，也不太清楚为什么，谢谢各位了。。

选项的细节不一样吧，刚看到这道题，D选项的discovery和后面的documenting不平行，在PREP语法笔记中A选项和D选项不是这样的。所以这道题大概就是在这个细节这改动了下吧...

这个地方 我一直有一个疑问：in addition to A,B...这个地方要求ab逻辑上对称么？？

小鱼1988

恩恩。。楼上的说的是！！！
我也不理解！！
哪位大牛帮帮忙呢！！

selinalover

我晕 我记得曾经问过 说是要对称 但是这个题就没有啊

selinalover

貌似 这个结构不要求对称的

wanjunshuai

我也有这个疑问，in addition to不需要逻辑主语对应的吗...把帖子顶上去，等大牛来解答~

in addition是不需要严格平行对称的，此题选A。做语法题还是得以理解意思为先，意思应表达简洁，明了
