When do I have to use 's' after noun ? and which one is correct ? Thanks.
How do I know if they are plural form or not ? Thanks a lot.
Thank for your correction.
But here are some clues:
If the verb is plural, then the subject will be.
The child is playing in the park.
The children are playing in the park.
If you know that a noun has two forms, one with an 's' and one without, the form with 's' will be a plural. dog/dogs.
Sometimes the singular and plural are the same. Even a native speaker cannot tell whether there is only one animal or more in the following:
He is playing with the sheep. What have you done with the fish.
In cases like this, you have to rely on the context.
