| 释义 | Contents overview passive modal structures : It can be done tomorrow.59 passive modal structures: It can be done tomorrow.Modal structures can be passivised.We can do it tomorrow. → It can be done tomorrow.They may close the hospital. → The hospital may be closed.An interesting, rather complicated point about modal verbs is that their meaning usually 'spreads over' a whole clause. This means that one can change a modal structure from active to passive, for example, without affecting the meaning very much. Compare:–A child could understand his theory.His theory could be understood by a child.–You shouldn't put adverbs between the verb and the object.Adverbs shouldn't be put between the verb and the object.–Dogs may chase cats.Cats may get chased by dogs.With most other verbs that are followed by infinitives, their meaning is attached to the subject, so that a change from active to passive changes the sense of the sentence completely. Compare:–Dogs like to chase cats.Cats like to be chased by dogs. (different and – of course – untrue)–Dan wants to phone Anna.Anna wants to be phoned by Dan. (not the same meaning)Previous Next |
