task 3

I was confused in using (s and , and ' ) in singular/plural , present simples' third person or possessive.So i mad mistakes grammatically.Some times i forgot to add 's' after the third person verbs.For example i did not know we have to add a 's' after verb which is coming in present simple tense: Everybody ,Anybody,Anyone ,Everyone.Recently,i decided to improve those parts of grammar.Thus i got a grammar book with a DVD and few advice from my friends and teacher .I practiced them and i think now i am able to use them correctly.In the following i will give several example and explanations.
-Everybody/Everyone..+ is/has: if we use present simple tens ,we must add 's' after verb which is coming in the following.
-Some times for a group of people we are using a singular adjective: the young the old the poor.
Some times we use 'a/an' as a singular before a group which we think it might be plural: a family is/has.... .
-If a plural noun is coming after an adjective we must use plural adjective: teenagers men/women.
-Another always is +singular . Ex: Can i have another biscuit?
-Other +plural . Ex: where are the other students?
I recommend the students to review these parts of grammar again because i can see every day that the students are using these incorrectly as well.
