If
you go with me, I will pay for the tickets.
Is this sentence about the future or the
present? The answer is the future. If it is about
the future, why do you use the simple present? That is another good
question.
When you write if-sentences (also called conditional
sentences), you often do NOT use the
tense that you are talking about.
Take a look at this sentence:
If oil is discovered in the desert, the
oil companies will make lots of money.
The sentence is about the future,
but the if-clause is NOT in the future. The result (also called the
result clause) is in the future.
However, the result is also NOT
always in the tense that the speaker is talking about. Take a look
at the following example.
If Matthew had enough money, he
would stay longer in Florida.
What tense (time) is the speaker
talking about? Future? Past? Present? The answer
is the present. So you must be thinking that this is really
confusing. Well, it isn't confusing if you know the rules.
To make things simple, let's say
there are 2 kinds of conditional sentences: true
and untrue.
For our purposes, untrue means a situation that is not real or even
impossible to happen.
TRUE
conditional sentences in the PRESENT |

If-clause |
Result clause |

places.
If the dog sees anybody close to his house, he is going to bark. |
And now the UNTRUE sentences...
UNTRUE
conditional sentences in the PRESENT |
|
If-clause |
Result clause |
Example |
Grammar >> |
simple past |
would + simple form of verb |
If I had enough money, I would invite you all to go
bowling. |
UNTRUE
conditional sentences in the FUTURE |
|
If-clause |
Result clause |
Example |
Grammar >> |
simple past |
would + simple form of verb |
If I had enough time, I would write her a letter next
week. |
UNTRUE
conditional sentences in the PAST |
|
If-clause |

Question: What does the following sentence mean?
Should you get a letter from the
bank, please give it to me.
No. This sentence is NOT
advice to a person about what he/she should (ought to) do. In this
situation, should means if. In English,
although the word if is very common, there are other words for if that allow you to be creative in your writing and
speech. The other words for if are:
Now, you are probably thinking:
"So, I can just take out if and put in one of the above
words." No. You can't do that. There are a few
simple rules for using these words.
Should is
used with TRUE
conditionals in the PRESENT
or FUTURE.
It is usually used when you are not very sure something will happen.
Example:
Should you get sick, call the
doctor immediately.
This is a good sentence, because you are not sure the person to whom you are talking will get
sick. Look at the following sentence.
Should water reach 100șC, it
will boil.
This is NOT a good way to use should. When water reaches 100șC, it always boils. It
is a law of nature.
It is also acceptable to use should AND
if in the same sentence. Notice
the position of should and if.
If you should
get sick, call the doctor immediately.
Were is
used with UNTRUE
conditionals in the PRESENT
or FUTURE when
the original sentence has were already in it.
If I were you, I would visit
grandma.
When using were, take
away the if and replace it with were only.
Were I you, I would visit
grandma.
Had is
used with UNTRUE
conditionals in the PAST.
If we had gone to Frank's Restaurant, we would have had great pizza.
If is taken out, and had is put in. Look at the following sentences.
Had we gone to Frank's Restaurant, we would have
had great pizza.
So, in
summary... |
