12. Although this company made a lot of money, it failed to make any contribution _____.
A. to help the poor B. to helping the poor
为什么B才是正确的
To 后不是+v.原形吗？

首先纠正一下，并不是所有to后面都加动词原形。
只有to作为动词不定式标志的时候，后面加动词原形。
而如果to是一个介词，后面一定要加doing。

这一题中to就是介词。make a contribution to doing是一个固定短语。

另外，contribution是可数名词，在这个句子中应该是contributions，我不明白为什么少了个s，你看看是不是抄错了。

contribution to 对…的贡献。。…是名词。所以helping the poor 选动名词

对...有所贡献
to 是介词，后面是名词性的。

此处的TO不是动词不定式TO DO的形式,它在此句中翻译成"为了".尽管这家公司的资金很多,但是它的破产是因为对穷困人民的捐助.

to在此是介词，后面需加ing形式。还有一些类似的，例如：look forward to doing,get down to doing.

应该是A呀,你的答案错了

Although this company made a lot of money, it failed to make any contribution _____. although this was not allowed acording中acording有什么用 although this was not allowed according to the rules of his office 用although造句~~ Although the accountant ptomised although 和 though的区别 though与although的区别 though, although有何区别 although与though有什么区别呢 although 和 though 用法有何区别？
