用动词的正确形式填空 i----(not be)my homework yesterday
用动词的正确形式填空 i----(not be)my homework yesterday

用动词的正确形式填空 i----(not be)my homework yesterday
do one's homework ,是昨天用didn't do.be应为 do

didn't do
因为时间是昨天,所以要用过去时

my brother是单数第三人称,所以应该用does的否定形式,doesn't;翻译:有分析:my brother为第三人称单数,助动词用dosen't。助动词后用动词原形,故

i did not do
yesterday ~ do 用 past tense

don‘t do

根据yesterday,谓语动词用过去的形式

didn't do
