Present tenses for advanced learners!

Hi,
If you think you know everything about present tenses, perhaps you should watch the following videos about ALL their uses.
Present Simple
Please, skip the 2 first minutes if you know how to form the present simple tense.

Did you remember all these uses of the present simple tense?
- Using the present simple to talk about regular actions.
- How to talk about general truths, states and situations using the present simple.
- How to describe long-lasting situations with the present simple.
- Using verbs of sensing, feeling, thinking or speaking with the present simple.
- How to use the present simple to tell jokes or stories in conversational English.
- Using the present simple in commentary, e.g. for a sports match.
- Using the present simple to talk about future schedules.

Present Continuous
Again, if you know how to form the present continuous you can skip the first minute and half (1.30 minutes).

 As you can see, apart from using the present continuous for expressing:
- that an action is going on
- or an arragement in the future,
you can also use it for expressing:
- disgusting repetition with the adequate adverb

Joining sentences with the relative pronouns: WHO, WHICH, WHERE, WHOSE

FORM & MEANING.
A relative clause tells us which thing or person the speaker means.
"The man who works in the bank is my brother" - 'who works in the bank' tells us which man.

• We use who in relative clauses for a person. Who is followed by a verb.
  
• We use whose in relative clauses instead of his/hers/theirs. Whose is followed by a noun.
  
• We use where in relative clauses to talk about a place. Where is followed by a noun or pronoun.
  
• We use which (and that) in relative clauses to talk about a thing.
  

USE.
Relative pronouns are words like who, which, where and whose. A relative pronoun serves two purposes. It acts as the subject or the object (who, which), the place (where) or possessive pronoun (whose) in the relative clause. It also serves as a conjunction connecting the two clauses.
Examples:
I have a friend. She lives in New England.
I have a friend who lives in New England.
