非大牛，看完prep笔记有点感觉，咱们讨论下吧~dying一般不使用，因为死亡是一个瞬间动作

第二题，being一般都错哈~并且根据比较，前面是landmark，后面应该是名词或从句，B选项being又不是从句又不是词组，而且后面还有一个is，这结构应该上来就排除

第三题，前面 decisions 已经提到了，所以用those指代，those就是补出的主语呀

最后， hourly rate 和wage不一样，wage是常指按周计算的工资，两者性质不同不能比，

那个C，what are... 是名词性从句，如果要指代前面rate应该也用单数

主句里面用的is哇

第2题，比较的前面是个从句，注意that, 后面比较的应该也是个从句，她被提升这件事比她是个女人这件事更有重要意义。
第3题，those指代decisions. 他的决定比其他人的决定更有影响。
第4题，B错在rate与wages不具备可比性；C错在what仅能指代rate of Allenby plant,也就是说别的公司提供的是A公司的rate,应该是A公司的rate与其他公司的rates相比。

我觉得第一题是不是B里后面的than错了？因为or less 算个插入语吧,than和前面的half不搭。
那如果去了or less, 后面的than应该是什么呢？

what不能指rates吗？因为后面是many factories 啊？
