In the sentence:
Which could be translated as "He is moving it by himself", the important information is 'by himself' (他一个人).
In English we could point to an ant and say "Look, he is moving it by himself". So the sentence can be used for both humans and animals.
What I am trying to find out is the correct way of changing this sentence so it could be used with something that is not a person (人).
Yesterday my son said:
When referring to an ant that had decided to carry off a large piece of something and he was impressed that the ant could do it "by himself". But the '一个人' part doesn't seem correct to me since the ant is not a person.
So is the right way to say this:
Or what is the right way to say this if you don't use '一个人', assuming that is incorrect.
