conditional + if

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 Sentence Type 1

→ It is possible and also very likely that the condition will be fulfilled.

Form: if + Simple Present, will-Future

Example: If I find her address, I’ll send her an invitation.


Conditional Sentence Type 2

→ It is possible but very unlikely, that the condition will be fulfilled.

Form: if + Simple Past, Conditional I (= would + Infinitive)

Example: If I found her address, I would send her an invitation.


Conditional Sentence Type 3

→ It is impossible that the condition will be fulfilled because it refers to the past.

COUNTABLE AND UNCOUNTABLE NOUNS

COUNTABLE NOUNS

Countable nouns are for things we can count using numbers. They have a singular and a plural form. The singular form can use the determiner "a" or "an". If you want to ask about the quantity of a countable noun, you ask "How many?" combined with the plural countable noun.

Singular                                  Plural
One dog                             Two dogs
One horse                          Two horses
One man                            Two men
One idea                            Two ideas
One shop                           Two shops

EXAMPLES:

* She has three dogs.
* I own a house.
* I would like two books please.
* How many friends do you have?

UNCOUNTABLE NOUNS

Uncountable nouns are for the things that we cannot count with numbers. They may be the names for abstract ideas or qualities or for physical objects that are too small or too amorphous to be counted (liquids, powders, gases, etc.). Uncountable nouns are used with a singular verb. They usually do not have a plural form.

EXAMPLES:

tea ,sugar, water, air, rice, knowledge, beauty, anger, fear, love, money, research, safety, evidence.

We cannot use a/an with these nouns. To express a quantity of an uncountable noun, use a word or expression like some, a lot of, much, a bit of, a great deal of , or else use an exact measurement like a cup of, a bag of, 1kg of, 1L of, a handful of, a pinch of, an hour of, a day of. If you want to ask about the quantity of an uncountable noun, you ask "How much?"

EXAMPLES:

* There has been a lot of researchinto the causes of this disease.
* He gave me a great deal of advicebefore my interview.
* Can you give me some information about uncountable nouns?
* He did not have much sugar left.
* Measure 1 cup of water, 300g of flour, and 1 teaspoon of salt.
* How much rice do you want?

Bad Shopping Experience in My Life
I had a bad experience when I did shopping because of the shop assistant’s fault. However, the security officer of the shop really embarrassed me of stealing a pair of blue jeans.
That was on Sunday afternoon. I went to a fashion shop with my friends. I chose a pair of blue jeans to buy and paid for them at the cashier. Unfortunately, the shop assistant was careless. She forgot to take the censor clip on the blue jeans. So, when I left the shop, the detector beeped. The security officer shouted at me, “Hey, you…! Stop!!”  Then, he took me to the manager’s room.
After examining, the security officer and the manager realized that it was not my fault. They said they were very sorry about what had happened. Finally, the manager asked me to take one piece of clothing for free.
Oh really bad experience for me but i'm so happy because i got free blue jeans...yeeaahhh!!!
