以下是引用ynjiao在2007-3-23 21:09:00的发言： "to do and do" ? OR "to do and to do"?? please team help me. OG 148. Under the Safe Drinking Water Act, the Environmental Protection Agency is required either to approve individual state plans for controlling the discharge of wastes into underground water or that they enforce their own plan for states without adequate regulations. (E) to enforce its OG 247. Faced with an estimated $2 billion budget gap, the city's mayor proposed a nearly 17 percent reduction in the amount allocated the previous year to maintain the city's major cultural institutions and to subsidize hundreds of local arts groups. (A) proposed a nearly 17 percent reduction in the amount allocated the previous year to maintain the city's major cultural institutions and to subsidize 上面的都没省略,可是以下几个都省略了.请帮忙解答 OG T47 eough to do and do T55 elect to do rather than do T82 be able to do and do ynjiao，做题好细心，佩服啊。虽然做对上述几道题与to是否省略没有太大关系。通常两个以上不定式并列时,后者的to常省掉;但是如果表示对比或对照关系时,后者的to不可以省掉。具体针对上述几题，我的几个看法供参考，欢迎大家讨论： 148、be required either to do or to do: 1). either ... or...肯定要绝对的平行对称，either to do or to do 中 or后面的to不能省略；2). 被动语态语态中to不可省略 （这条记得当年白大侠讲过，但不大记得是否被动语态平行结构中to也不可省略，有待考证）； 247、to subsidize 省略to，那么会指代不清楚，结果上subsidize成了the city's mayor 的谓语，但时态、语态上又不对； 如果不是如247中的例子，而是一般用法propose sth to do and do，我觉得是可以省略后面to的（有待考证）； 47+55: enough to do and do; rather than:习惯性用法，省略后面to； 82: be able to do and do: be able to 从语义角度分析是情态动词，是固定格式，它表示能力，情态动词 + do and do，如果后面加to反而是多余的。 朝阳2组的3.25小组学习可以顺便讨论一下，人大3.31我会和大家一起讨论，这5道题都是出自OG10th
