What is the difference between "these" and "those"?

THESE

1) used to point at many objects that are infront of you/near you.

e.g. These cars are all red.

e.g. These students won awards.

e.g. These policemen caught the burglar.

2) Used to talk about present time (in plural)

e.g. These days have been hard on us.

e.g. I haven't slept much these last few months

THOSE

1) Used to talk about many objects that are far away from you.

e.g. Do you see those trees? (It would mean that the trees aren't infront of you)

e.g. These students did well in the exam. Those students, standing over there, did not do well in the exam.

e.g. These policemen caught those robbers.

2) Used to talk about past/future times (in plural)

e.g. I was born in 1988. In those days, we didn't have the internet and people talked more.

e.g. Those were the best years of my life.

e.g. Those months will pass quickly.

Difference Between These And Those

These - Could mean your directing your feelings towards something your holding, or standing next to, or you have tasted, or whatever the case. Directing something now, or is the present. Im at the dinner table, and these grapes are discusting.

Those - Could mean your directing your feelings to an object you have tasted, held, whatever the case. Im at the dinner table. I dont like those. these taste better.

Sorry i probably didnt explain well enough

I believe it has to do with the distance the item is from the speaker. If the things are close, you would say "these"; however, if they were farther away, you would say "those".

Ex.

Marcia is looking at a pair of shoes. She says, "I do not like these shoes". Marcia sees prettier shoes in the distance. She says, "I think those shoes are more stylish".

Hope I helped :)

These: plural of this

Those: plural of that
