Elements of the periodic table that i'm supposed to be memorizing,theorems that i'm supposed to be understanding.
1.请问在这里am supposed to be memorize表示的是“应该”,表示责任义务吗?我应该正在背诵记忆(元素周期表);但是实际情况是说话人最近很忙,睡前说的一句话。
2.既然表示现在并非在做此事,是不是可以用was supposed to be doing表示,那这里为什么用am supposed to呢?还是表示一般的情况:最近都要忙于背书,并非此刻正在背书?
be supposed to do sth 大约等于should do sth. 表示责任、义务。当不定式改为进行体时,则等于should be doing sth. 即本该现在正在做某事而实际没有做。比如一个小孩在本该做作业的时间看电视,他母亲就会说 You should be doing your homework now. 或者 You are supposed to be doing your homework now.
