助动词是过去式时谓语动词为原形吗? a stranger was notice enter the building just now. notice对吗

不对,这里是被动语态,应该是noticed。同时还有另一个重要问题,enter前面应该有一个不定式符号to.注意:在主动句中,notice后面的不定式要省去“to”,但在被动句中,要把“to”加上,如:I noticed a stranger enter the building just now.→A stranger was noticed to enter the building just now.

应该是noticed。因为主语是被动的,谓语应该用被动态。如果主语是主动的,
那么应该用过去进行时,比如说:I was reading when you entered my room
last night. 这位同学是各种时态没搞懂。

不对
是noticed
被动语态 :被注意到
