Hi thanks a lot for the help my question is ,why can not i say."They can do both listen and speak at the same time",i mean why do i need the (ING) or gerund?.please any good explanation will be good.i highly appreciate it.
Also another question,do i say:"all that i did was running "or all that i did was run
Hi Clive ,thank you very much.Now ,for intance,where you stated that i could say "all that i did was run".My question is why can i say RUN there and not be obligated to say RUNNING ,because as far as i know after any verb (like to be in this case )you have to use the gerund ,no?
as far as i know after any verb (like to be in this case )you have to use the gerund ,no? No. It depends on the particular verb. Some verbs require a gerund, some the infinitive. With some you can use either, giving different meanings.
I think the best way I can try to help you is if you give me some examples that are puzzling you. Then I can try to explain. Talking about examples is better that talking about the language in a general way.
