1. There are three ways to pronounce the words ending with -s:
- [s] after a voiceless sound such as k, f, p, t, or θ (voiceless sound produces no vibration of vocal chords): cats, hats, weeks - [z] after a voiced sound such as ð, b, d, g, j, l, m, n, <span>ŋ, r, v, w </span>(voiced sound produces vibration of vocal chords): dogs, gloves, wolves, lives - [ɪz] after these sounds: [tʃ], [dʒ], [s], [z] (because it would be impossible to pronounce such plural words without an additional sound [ɪ]: cockroaches, watches, bridges, buses, traces, blazes
2. There are three ways to pronounce the words ending with -d:

A pronoun is something that replaces a noun like for instance take a table. If you have mentioned a table many times and it is getting a bit repetitive, use the word it instead of table. The same here happens for the word she. Let’s say her name was Linda. Linda went to the shop. Linda watched TV. Linda fell asleep. It’s a bit repetitive. So you would say Linda went to the shop. She watched TV. She sell asleep.
Okay, so as long as you have certain conditions, it can be a sentence. Therefore, you can spend a quick amount of time writing these. You need a noun and a verb, which is why these are quick.
