答案C
從as well的詞組組合,排除a和b
may [might] (just) as well…
意為“不妨”、“還是…為好”等,用 might 比用 may 語氣更委婉.
如：
I’m ready,so I might as well go now．
我已準備好,因此不妨現(xiàn)在就走.
There’s nothing to do,so I may [might] as well go to bed.
既然沒什么事可做,我還是去睡覺為好.
注：might as well 還可用于指過去的情況或用于比較兩個令人不愉快的情況：
This holiday isn’t much fun; we might as well be back home.這個假日過得真沒意思,我們還不如呆在家里.
本句Might some of the suggestions prove of value to you as well?
有些建議會向你證明還是有些用處的.
