do后面接动词原形,是因为do后面的人称是复数形式,所以要接动词原形。如果一个特殊疑问句或一般疑问句是以do开头的。意味着他后面的人称代词是复数形式。既然人称代词为复数形式。他后面的动词,就必须要用原形动词。这是英语当中一个最重要的语法规则。
do后面加动词原形吗
这个要看do是做实义动词,还是助动词了。具体根据上下文来确定。如果是助动词用法的话,那就直接加动词原形。如果是实义动词的用法,是直接跟宾语的,那么如果是加动词的话,就要用动词的-ing形式,即动名词形式。
do + 动词原形,表示对动作的强调
例句:I remembered that Justin did return home last night.
我记得Justin昨晚确实回过家。
I did make somewonderfulpictures later.
do +动词原形 表示强调“的确如此”。do须根据时态和人称进行变化,后面动词要用原形。如:
(1) I do like the landscape.
我的确喜欢这个自然风光。
(2) He does want to go to America for future study.
他的确想去美国深造。
(3) They do go to the theatre yesterday.
他们昨天的确去看戏了。
