一道英语题......求答案与详解......

选A
相当于i advise us to go on an excursion this weekend.
suggest doing也可以加动名词的符合宾语suggest sb doing .
I suggested / proposed his / him giving up the foolish idea. 我建议他放弃那愚蠢的念头.(suggest和propose在口语里可接动名词的复合宾语).
suggest that (should) do
suggest + n.

A,suggest后面只能接doing sth.

C

当suggest当建议和提议的意思时
后面可加名词，动名词和that从句，但是不接人称代词
当接that时后面从句+should+动词原形，should可以省略

suggest doing sth

suggest后面跟的是宾语，对于人称代词we就理应用宾格，所以便是us。这样就选A。
