B had spent half as much time attending his classes as he did to complain
C were to spend half as much time attending his classes as he does complaining
D were to spend half as much time attending his classes as complaining
E should spend half as much time attending his classes as to complain

the answer is A
但是注動詞後面為什麼會加ing?

嗯嗯...斷句應該是這樣子的(藍色部分)
所以spent後面接的動詞是complain,所以要加ing~~

這題還是妙！did代spend，所以：did complaining...成為正確答案！

[Ethan]

spend (in); the preposition IN can be omitted.

[gogotu]

spend (in); the preposition IN can be omitted.

你是說：
spend ...time in...as he did (spend time) (in) complaining...

OG133
spend time or money on N
請問spend的用法是on N
in Ving嗎?

[Calvin]

to titin

spend money or time " ON " s'th

use time doing s'th ---> spend (in) V-ing (action)
