各时态的主系表结构的对比 我们以基本句子“他是老师”进行各时态的对比,大家要注意观察动词的时态的变化,即动词形式的变化,注意其相同点和不同点。 1) He was a
teacher.他过去是教师。(一般过去时) 2) He is a
teacher.他现在是教师。(一般现在时) 3) He is going to be a teacher when he grows
up.他长大要当老师。(一般将来时) He will be a teacher when he grows
up.他长大要当老师。(一般将来时) 4) He said that he wasgoingtobeateacherwhen
he grew up.他说他长大要当老师。(一般过去将来时) He said that he would be a teacher when he grew
up.他说他长大要当老师。(一般过去将来时) 5) He has been a teacher since he came
here.自从他来这他就一直当老师。(现在完成时) 6) He had been a teacher for ten years
by theend of last
month.到上月底他当老师已经10年了。(过去完成时态) 由此可见,主系表结构不用于进行时态,由于不是及物动词,不表示动作,也就没有被动语态。(刘昱祥原创)
