Hi. Can someone explain to me why in the following sentence, we do not have to BE verb while using the -ing tense:
" Many dogs work for humans, doing jobs such as, helping the blind, helping the police...and even racing."
My question : why isnt doing, helping and racing prefixed by are ? Isnt it the -ing tense? If not what is it please?
Thankyou for your help.
Ex: Many dogs work for humans, doing jobs such as, helping the blind, helping the police...and even racing.
The underlined words are not verbs. Just because they end in -ing doesn't mean they are verbs. The fact that they don't take a BE verb tells us they are nominal, meaning they are not verbs:
- Many dogs work for humans by doing jobs such as this job: helping the blind, and this job: helping the police, and they even do this job: racing.
