Write an article based on this "Use these to replace nouns that are nearby in space and time. Use these to refer to something that is physically nearby. Use these to describe when something is figuratively nearby. Use these to introduce people to others."
If the noun you are referring to is near to you, either physically or figuratively, you can replace it with these.  I'm holding three chocolate bars. Do you want all of these? (These replaces chocolate bars.) Would you like to borrow some books? Here, take these. (These replaces books.)  These are so beautiful! Thank you for the flowers. (These replaces flowers.) This and these are both used to refer to something that is closer to the speaker. You can use these to draw particular attention to items.   These books on the shelf belong to Rajeev. [The books are near the speaker.] Look at all these bracelets on my wrist! [The bracelets are on the speaker's wrist, so they're nearby.] Who put these cupcakes in the refrigerator? [Presumably, the speaker is close to the cupcakes.] This and these are also used to express figurative distances, particularly distances having to do with time. Use these when something is happening in the present, has happened in the recent past, or will happen in the near future.   These shows I've been watching are absolutely extraordinary. [The shows have been watched in the recent past.] Have you seen these letters to the editor in today's news? [The letters have been published in today's newspaper.] Why don't you take these books with you when you go? [The books will be taken by the other person in the near future.] If you are introducing more than one person to someone else, you can use these to begin your sentence.  For example: "These are my classmates, Sean and Adrienne." However, in English we do not use these to refer directly to people: "These are Sean and Adrienne" is incorrect. Instead, you would say "This is Sean and this is Adrienne." If introducing yourself, as when answering the phone, use this: "Hello, this is Chang."
