1. The Simple Past Tense and The Present Perfect

The simple past tense indicates that an activity or situation began and ended at a particular time in the past. 

The present perfect expresses the idea that something happened (or never happened) before now, at an unspecified time in the past.The exact time it happened is not important. It also expresses the repetition of an activity before now. The exact time of each repetition is not important.

Example :

• The plane crashed there.
• The plane has crashed there.

2. Subject Verb Agreement

Subject-verb agreement just means using the right version of the verb to agree with the subject. For example:

• One dog is sitting on the grass
• Two dogs are sitting on the grass

In other words, should you be using a singular verb (like is and plays) or should you be using a plural one (like are and play)?

• No one knows what he can do till he tries (Publilius Syrus, circa 100 BC)
• The supreme irony of life is that hardly anyone gets out of it alive .

3. Possesive Pronouns and Adjective Pronouns


Possessive pronouns and adjectives are two different ways to show possession in English. Possessive adjectives go before the noun and possessive pronouns go after the noun

Noun + Possesive Pronouns
Example :

• The dog is mine
• The brown cat is hers

Possesive Adjective + Noun
Example :

• Her cat is brown
• My dog is big

4. Collective Noun


A collective noun is a noun that refers to a group of entities that may be considered either as individuals or as one larger entity.

Examples
	Club Examples: It is a large club. They are a large club. Gang Examples: The gang’s all here. The gang are all here.
