these days we have spent as much time as we---the national flower exhibition 能不能用could to prepa

题目

these days we have spent as much time as we---the national flower exhibition 能不能用could to prepa
could to prepare 作状语？但答案是could preparing

答案

这个题答案是有争议的,不过更多的人倾向于使用v-ing：
【These days时间状语】【 we】【 have spent】【 as much time宾语】 【as we could 状语从句】【preparing】the national flower exhibition
spend time doing sth
但是,其实用to prepare也有道理,因为符合句型结构——
do all/everything
as much as
what/whatever one can/could to do sth
意思是：
做某人所能够做的一切/尽可能多的/无论什么来做某事.后面用带to不定式做目的状语.
像这种有争议的题,一般只需要知道分析方法和所考知识点就行了,不必过多的花费心思,因为争论者各执一词,其实并没有实际意义.再说了,像这种问题说穿了就是【失误题】,正式高考中很罕见!
祝你开心如意!
