For instance, how do I know when to use them or they?

anonymous · Answer

I'm not very sure, but I think it should become they..they is used when they perform actions similar to the subject

anonymous · Answer

yay it's right, that's what I thought too, but then again some of them are still tricky.

anonymous · Answer

That's why my parents had to spend more time with them than with us. How about this one sometimes us can be changed to we, do you know when these are to be used?

anonymous · Answer

we does the actions in the sentence

anonymous · Answer

I mean perform, sorry.

anonymous · Answer

okay thank you... can you give like an example for both

anonymous · Answer

I think that one sentence would stay as is because they are currently doing the action

anonymous · Answer

We will conquer the world.
The world will be conquered by us. 

Another one to add, we is used with verbs in the present tense while us does not. Us is also a direct object, indirect object, and the object of the preposition.
