conditional sentences

Conditional Sentences.

Independent and dependent clauses are the building blocks of sentences. A single independent clause can be a sentence, by itself. However, dependent clauses are used to make sentences more complete and more interesting. Using conjunctions and proper punctuation, dependent and independent clauses can be joined together to create interesting and complex compound sentences that are fun and engaging to read.

An independent clause is a clause that can stand on its own, by itself. It does not need to be joined to any other clauses, because it contains all the information necessary to be a complete sentences.
Independent clauses have three components:

1.     They have a subject - they tell the reader what the sentence is about.
2.     They have an action or predicate - they tell the reader what the subject is doing.
3.     They express a complete thought - something happened or was said.

An independent clause can be as simple as a subject and a verb:
Example : Jim reads.

Conditional Sentences are also known as Conditional Clauses or If Clauses. They are used to express that the action in the main clause (without if) can only take place if a certain condition (in the clause with if) is fulfilled. There are three types of Conditional Sentences.

Conditional sentences are statements discussing known factors or hypothetical situations and their consequences. Complete conditional sentences contain a conditional clause (often referred to as the if-clause) and the consequence. Consider the following sentences:

Example :
·        If a certain condition is true, then a particular result happens.
·        I would travel around the world if I won the lottery.
·        When water reaches 100 degrees, it boils.

1.     How to Use First Conditional Sentences (type 1)
First conditional sentences are used to express situations in which the outcome is likely (but not guaranteed) to happen in the future.

It is possible and also very likely that the condition will be fulfilled.
Form: if + Simple Present, will-Future

Look at the examples below:
Example :
·        If you rest, you will feel better.
·        If you set your mind to a goal, you’ll eventually achieve it.

Note: that we use the simple present tense in the if-clause and simple future tense in the main clause—that is, the clause that expresses the likely outcome. This is how we indicate that under a certain condition (as expressed in the if-clause), a specific result will likely happen in the future. Examine some of the common mistakes people make using the first conditional structure:

Example :
Incorrect : If you will rest , you will feel better.
Correct : If you rest , you will feel better.

Explanation: Use the simple present tense in the if-clause.

Incorrect : If you set your mind to a goal, you eventually achieve it.
Correct : If you set your mind to a goal, you’ll eventually achieve it.

Explanation: Use the zero conditional (i.e., simple present + simple present) only when a certain result is guaranteed. If the result is likely, use the first conditional (i.e., simple present + simple future).

2.     How to Use Second Conditional Sentences (type 2)
Second conditional sentences are useful for expressing outcomes that are completely unrealistic or will not likely happen in the future.

It is possible but very unlikely, that the condition will be fulfilled.
Form: if + Simple Past, Conditional I (= would + Infinitive)
Consider the examples below:

Example :
·        If I inherited a billion dollars, I would travel to the moon.
·        If I owned a zoo, I might let people interact with the animals more.

Notice the correct way to structure second conditional sentences is to use the simple past tense in the if-clause and an auxiliary modal verb (e.g., could, should, would, might) in the main clause (the one that expresses the unrealistic or unlikely outcome). The following sentences illustrate a couple of the common mistakes people make when using the second conditional:

Example :
Incorrect : If I inherit a billion dollars, I would travel to the moon.
Correct : If I inherited a billion dollars, I would travel to the moon.
Explanation: When applying the second conditional, use the simple past tense in the if-clause.

Incorrect : If I owned a zoo, I will let people interact with the animals more.
Correct : If I owned a zoo, I might let people interact with the animals more.
Explanation: Use a modal auxiliary verb in the main clause when using the second conditional mood to express the unlikelihood that the result will actually happen.

3.     How to Use Third Conditional Sentences (type 3)
Third conditional sentences are used to explain that present circumstances would be different if something different had happened in the past.

It is impossible that the condition will be fulfilled because it refers to the past.
Form: if + Past Perfect, Conditional II (= would + have + Past Participle)
Look at the following examples:

Example :
·        If you had told me you needed a ride, I would have left earlier.
·        If I had cleaned the house, I could have gone to the movies.

These sentences express a condition that was likely enough, but did not actually happen in the past. The speaker in the first sentence was capable of leaving early, but did not. Along these same lines, the speaker in the second sentence was capable of cleaning the house, but did not. These are all conditions that were likely, but regrettably did not happen.

Note: that when using the third conditional, we use the past perfect (i.e., had + past participle) in the if-clause. The modal auxiliary (would, could, shoud, etc.) + have + past participle in the main clause expresses the theoretical situation that could have happened.
Consider these common mistakes when applying the third conditional:

Example :
Incorrect : If you would have told me you needed a ride, I would have left earlier.
Correct : If you had told me you needed a ride, I would have left earlier.
Explanation: With third conditional sentences, do not use a modal auxiliary verb in the if-clause.

Incorrect : If I had cleaned the house, I could go to the movies.
Correct : If I had cleaned the house, I could have gone to the movies.
Explanation: The third conditional mood expresses a situation that could have only happened in the past if a certain condition had been met. That’s why we use the modal auxiliary verb + have + the past participle.

Exceptions and Special Cases When Using Conditional Sentences

As with most topics in the English language, conditional sentences often present special cases in which unique rules must be applied.

1.     Use of the Simple Future in the If-Clause
Generally speaking, the simple future should be used only in the main clause. One exception is when the action in the if-clause will take place after the action in the main clause. For example, consider the following sentence:
·        If aspirin will ease my headache, I will take a couple tonight.
The action in the if-clause is the aspirin easing the headache, which will take place only after the speaker takes them later that night.

2.     “Were to” in the If-Clause
The verb phrase were to is sometimes used in conditional sentences when the likely or unlikely result is particularly awful or unthinkable. In this case, were to is used to place emphasis on this potential outcome. Consider these sentences:
·        If I were to be sick, I would miss another day of work.
·        If she were to be late again, she would have to have a conference with the manager.
·        If the rent were to have been a penny more, they would not have been able to pay it.
Note:  that the emphatic “were to” can be used to describe hypothetical scenarios in the present, future, and past.

3.     Punctuating Conditional Sentences
Despite the complex nature of conditional sentences, punctuating them properly is really simple!
Here’s the skinny:
Use a comma after the if-clause when the if-clause precedes the main clause.
·        If I’d had time, I would have cleaned the house.
·        If the main clause precedes the if-clause, no punctuation is necessary.
·        I would have cleaned the house if I’d had time.

Rules to used conditional sentences :
1.     It’s important to use the correct structure for each of these different conditional sentences because they express varying meanings.
2.     Pay attention to verb tense when using different conditional modes.
3.     Use a comma after the if-clause when the if-clause precedes the main clause.

The expressions 'I wish' and 'If only' are used in English to express wishes and regrets about things that may happen in the future or may have happened in the past.
When I wish and if only are used, they follow the structure of one of these conditionals, depending on what we want to express. If we talk about a regret about a present or future event, then we will use the structure of the second type of conditional and the expressions I wish/if only are followed by past simple:

Example :
·        I wish I had enough money to travel to New York. 
·        If only I had enough money to travel to New York.
(That is, I don't have enough money, and I am sorry for it because I can't go)

If the event we regret happened (or failed to happen) in the past and is, therefore, impossible to change, then we use the third type of conditional structure. This time the expressions I wish/if only are followed by past perfect.

Example :
·        I wish I had had enough money to travel to New York. 
·        If only I had had enough money to travel to New York.
(That is, I didn't have enough money to travel, so I couldn't go and now I regret it).

ACTIVE AND PASSIVE VOICE


Nanda Putri Ayu Lestari / 4SA02 / 14615974

Active and Passive Voice

Active voice describes a sentence where the subject performs the action stated by the verb.
In passive voice sentences, the subject is acted upon by the verb.

Use of Passive
Passive voice is used when the focus is on the action. It is not important or not known, however, who or what is performing the action.
Example: My bike was stolen.
In the example above, the focus is on the fact that my bike was stolen. I do not know, however, who did it.
Sometimes a statement in passive is more polite than active voice, as the following example shows:
Example: A mistake was made.
In this case, I focus on the fact that a mistake was made, but I do not blame anyone (e.g. You have made a mistake.).

When rewriting active sentences in passive voice, note the following:
·         the object of the active sentence becomes the subject of the passive sentence
·         the finite form of the verb is changed (to be + past participle)
·         the subject of the active sentence becomes the object of the passive sentence (or is dropped)

These sentences are in passive voice. The Passive voice is used in English 

(a) To stress the action done rather than the doer of the action
(b) If the doer is unknown
(c) When it is more convenient.


Rules for changing Active Voice into Passive Voice:
  • · Identify the subject, the verb and the object: SVO 
  • · Change the object into subject 
  • · Put the suitable helping verb or auxiliary verb. In case helping verb is given, use the same. But note that the helping verb given agrees with the object. 
  • · Change the verb into past participle of the verb. 
  • · Add the preposition "by" 
  • · Change the subject into object. 

USING THE AUXILIARY VERB “BE”

The passive voice is formed by using a form of the auxiliary verb “be” (be, am, is, are, was, were, being, been) followed by the past participle of the main verb.

Active = He loves me. We took our children to the circus. A thief stole my money.
Passive = I am loved. The children were taken to the circus. My money was stolen.
Notice how the “be” auxiliaries change the meaning of the verbs from action to condition or from “doing” to “being.”

He remembers his grandmother. (“he” is doing an action: remembering)
His grandmother is remembered. (“she” is in a condition: being remembered)

In this way, the past participle functions very much like an adjective; it describes the subject . The woman is pretty. She is a pretty woman The woman is married. She is a married woman.

VERB TENSES USED IN ACTIVE AND PASSIVE VOICE

The following is a summary of active and passive forms of all verb tenses. Remember that in active forms the subject of the sentence is the person or thing that does the action. In passive constructions, the verb is performed by someone or something other than the subject; often, the action is done to the subject by someone else.

Present Time
• Simple Present
Use the simple present tense to make a generalization, to present a state of being, or to indicate a habitual or repeated action.
Active = base form or “-s/-es” form.
Passive = am/is/are + past participle
Active = Professor Brown teaches at Hunter.
 All humans are equal.
 Maria eats in the cafeteria.
Passive = Sonia is taught by Professor Brown.
   All humans are created equal.
    The cafeteria is cleaned.

• Present Progressive
Use the present progressive to describe an ongoing activity or a temporary action.
Active = am/is/are + -ing
Passive = am/is/are + being + -ed/-en
Active = The students are learning Spanish. .
  I am working at McDonald’s until I finish school.
Passive = Classes are being conducted in Spanish.
    He is being hired to work at McDonald’s

·  Present Perfect
Use the present perfect to describe an action occurring in the past but relevant to the present, or extending to the present.
Active = has/have + -ed/-en
Hunter has opened a language institute in East Harlem.
Passive = has/have + been + -ed/-en
The language institute has been opened to relocate students off the main campus.

• Present Perfect Progressive
Use the present perfect progressive to describe an ongoing action beginning before now and is still relevant to the present.

Active = has/have + been + -ing
Hunter has been awarding BA and MA diplomas for over one hundred years.
Passive = has/have + been + being + -ed/-en
Note: Because of awkward construction, the perfect progressive form is not used in the passive voice. Instead, an adverb may be used to show continuing action: “We have been repeatedly scolded for being late.”

Past Time
• Simple Past
Use the simple past to indicate a general or habitual action occurring in the past or at a specific time in the past.
Active = base + -ed or irregular form
Our family bought all our clothes at Sears when I was young.
Passive = was/were + -ed/-en
The clothes were bought by my mother

In informal conversation, speakers of English often express habitual behavior in the past using the modal “would.”
Active = would + base
We would usually eat burgers in the food court.
Passive = would + be + -ed/-en
Most of the french fries would be eaten before we got to the table.

• Past Progressive
Use the past progressive to indicate an ongoing action in the past or an action continuing through a specific past time.
Active = was/were + -ing
Mary and Paul were dating in those days.
Passive = was/were + being + -ed/-en
One afternoon, Mary was being kissed by Paul when her mother passed by.

• Past Perfect
Use the past perfect to indicate an action completed prior to a particular time or before another action in the past.
Active = had + -ed/-en
Completed: Mary's mother was shocked because she had forbidden her daughter to date.
Passive = had + been + -ed/-en
Mary had been kissed many times before that day.

• Past Perfect Progressive
Use the past perfect progressive to indicate a continuing action that began before a past action or time.
Active = had + been + -ing
Mary had been trying to tell her mother about Paul for a long time.

Passive = had + been + being + -ed/-en

Future Time
• Simple Future
Use the future to indicate an action that is expected to take place at a future time.
Active = will + base
Paul and Mary will marry in June.
Passive = will + be + -ed/-en
They will be married by a priest and a rabbi.
Active = or am/is/are going to + base
Mary is going to wear her grandmother's gown
Passive = or am/is/are + going to be + -ed/-en.

Passive = will + be + being + -ed/en
Note: Not used in the passive voice.

• Future Perfect
Use the future perfect to indicate a future action expected to be completed before another future action or time.
Active = will + have + -ed/-en
