Conditional sentences




ZERO TYPE CONDITIONAL SENTENCES

MEANING& USE
The zero conditional is used to make statements about the real world, and often refers to general truths, such as scientific facts. In these sentences, the time is the present or always and the situation is real and possible.
  • If you heat water, it boils.
  • Water boils if you heat it.
  • When you heat ice, it melts.
  • Ice melts when you heat it.
  • If it snows, the grass gets white.
  • The grass gets white if it snows.
  • When it rains, the grass gets wet.
  • The grass gets wet when it rains.

FORM
We can make a zero conditional sentence with two present simple verbs (one in the 'if clause' and one in the 'main clause'):

If/when/unless + present simple, .... present simple.

EXERCISES
1ST TYPE CONDITIONAL SENTENCES

MEANING & USE
The first conditional is also called the "real" conditional because it is used for real, or possible, situations. These situations take place if a certain condition is met.

In the first conditional we can salso use unless, which means "if... not". In other words, "... unless he hurries up" could also be written, "... if he doesn't hurry up."
1st type conditional sentence
  • If it rains, we will stay at home.
  • He will arrive late unless he hurries up.
  • Sophie will buy a new car, if she gets her raise.


FORM
The first conditional is formed by the use of the present simple in the if clause followed by a comma and a future simple verb (will + infinitive) in the result clause. You can also put the result clause first without using a comma between the clauses.
  • If he finishes on time, we will go to the movies.
OR
  • We will go to the movies if he finishes on time.

EXERCISES

2nd TYPE CONDITIONAL SENTENCES

MEANING
2nd type conditional sentence
The second conditional is used to talk about situations or actions in the present or future which are not likely to happen or are imaginary, hypothetical or impossible.






  • If I were a rich woman, I would travel around the world. I think it is very unlikely that I will be rich. However, in this unlikely condition, I will travel around the world.
  • If I weren't / wasn't watching TV now, I would be playing tennis. I am watching TV, but I am imagining an alternative activity I would be doing if I wasn't watching TV
  • If you had a bigger dog, your house would be protected. You don't have a big dog, but I am imagining how protected you would be if you had one.
  • If I were an alien, I would be able to travel around the universe. It is impossible for me to be an alien. However, I am imagining what I would do in this situation.
  • We would go to Paris this summer if we passed all our subjects. That is our plan but, unfortunatelly,  we know we are not going to pass all our subjects.
FORM
If + past simple + conditional (would)
Conditional (would) + if + past simple
Verb be is usually were for all subjects; was (1st & 3rd person) is colloquial.

SONGS
If I were a rich man (Fiddler in the Roof-movie)
If I were a boy (Beyonce)

EXERCISES

3RD TYPE CONDITIONAL SENTENCES

MEANING
The first conditional and second conditionals tell us about the future. With the third conditional we refer to the past. We speak about a condition in the past that did not happen. That is why there is no possibility for this condition. The third conditional is also like a dream, but with no possibility of the dream coming true.
  • If I had travelled to Italy I would have visited Luca. But I have not travelled to Italy and, therefore, I have not visited Luca.
  • If you had got a good mark, would you have complained to the teacher? but your mark was bad, so we don't know for sure what you would have done.
  • What would you have done if it had snowed last weekend? but it didn't snow.
  • I wouldn't have called if I had known that she wasn't home. but I knew so I called

Past participle // if + past perfect

Passive sentences in English

WHAT IS A PASSIVE STRUCTURE?
Active sentences usually focus on who did the action:
  • My sister broke the window.
Whereas passive sentences usually focus on who or what suffered the effects of the action:
  • The window was broken.
On most occassions the agent (who did the action) is not mentioned but, if relevant, it can be mentioned after the preposition by.
  • The window was broken by my sister.
  • Don Quixote was written by Cervantes.

HOW IS IT MADE?
Passive structures have these elements:
  1. the passive subject (my sister)
  2. verb be in the right tense (the same tense that would be used in the corresponding active structure)
  3. the past participle of the lexical verb
  4. only if necessary, the agent (by + ______)
CHANGING ACTIVE SENTENCES  INTO THE PASSIVE
  1. The object of the active sentence becomes the subject in the passive structure
  2. verb be in the same tense as the active verb in the active structure
  3. past participle of the main verb
  4. the subjet of the active sentence becames the object in the passive structure (by + agent)
    • Peter builds a house. -> A house is built by Peter.
    • They were cooking dinner when we arrived. -> Dinner was being cooked when we arrived.
    • I will finish it tomorrow. -> It will be finished tomorrow.





PASSIVE SENTENCES WITH TWO SUBJECTS (ONLY ESO-4)
Some active sentences have both a direct and an indirect object. In English both can be the subject in a passive structure. The indirect object is introduced by to in the passive sentence.
  • ACTIVE: My sister asked me a question.
  • PASSIVE 1: A question was asked to me.
  • PASSIVE 2: I was asked a question.
  • ACTIVE. The teacher explained the exercise to the students.
  • PASSIVE 1: The exercise was explained to the students.
  • PASSIVE 2: The studens were explained the exercise.

Relative sentences

RELATIVE PRONOUNS
  • who → when we talk about people
  • which → when we talk about things
  • whose → instead of his/her or their
  • We also use that for who/which.
  • where → when we speak about places
  • when → when we speak about a period of time






OMISSION OF THE RELATIVE PRONOUN
We leave out the relative pronoun (who/which/that) if it is not the subject in the sentence.
  • That is the book I like.
If there is a verb after the relative pronoun who/which/that, do not leave out the relative pronoun.
  • He is the teacher who spoke to us yesterday morning.

TYPES OF RELATIVE CLAUSES

http://4thgradeela.weebly.com/uploads/2/0/7/7/20771340/5289752_orig.jpg
To understand the distinctions between that and which it is necessary to understand defining (restrictive) and non-defining (non-restrictive) clauses.
Learning these distinctions is one technical aspect of grammar that every user of English should understand, because it is at the root of an assortment of grammatical errors.

NON DEFINING RELATIVE CLAUSES

A non-defining, or non-restrictive, clause is one that can be regarded as parenthetical:

  • My house, which has a blue door, needs painting.
The italicized words are effectively an aside and could be deleted. The real point of the sentence is that the house needs painting; the blue door is incidental.
Use commas to set off non-defining elements, which contribute to, but do not determine, the meaning of the sentence. These elements may be clauses (groups of words that contain a subject and a verb) or phrases (groups of words that do not contain both a subject and a verb).

DEFINING RELATIVE CLAUSES

A defining, restrictive, clause is one that is essential to the sense of the sentence.

  • My house that has a blue door needs painting.
Here the blue door is a defining characteristic, it helps to distinguish that house from my other houses.
Defining clauses or phrases are not separated off with commas. A restrictive clause or phrase is essential to the meaning of the sentence; it defines the word it modifies by ›restricting‹ its meaning. Eliminating a restrictive element from a sentence changes its meaning dramatically.
