after lunch i'm going to do my homework.i think i ()do it better than before.A am B am going

问题描述:

after lunch i'm going to do my homework.i think i ()do it better than before.A am B am going
C can D would

此题选C,AB选项与后面的那个单词do不搭配,D选项不符合,此处主要强调的是我的这个能力,而非意愿,D强调的是意愿请问i think 开头的句子从句是不是都要用一般现在时?不一定啊,比如 i think i could do it better if i had studied hard
