 Re: as of & from
thank you for you answer susan; and I've got some ideas.
for FROM/AS FROM/AS OF, a famous English teacher(not native speaker but proficient)tells me, past tense should be used, even though the event is continuing, and the present perfect tense should be used when SINCE is used. He also said that a sentence like We have been told to learn Mandarin from 1921 is usually regarded as wrong by strict grammarians, and open-minded ones will consider it OK. susan do you think it's absolutely correct? |
