There is there are

 There is / there are

"There" is a kind of pronoun used to show something you know exists.

Compare these two sentences:
- "A fly is in my soup."
- "There is a fly in my soup!"
The first sentence is factual and impersonal. The fly is the subject, and the soup is the object. In the second sentence the object is "a fly in my soup", so the subject is "There". "There" functions as a kind of dummy subject that represents a more personal perspective, rather than a factual statement.

Especially in spoken English we usually use the contraction "there's", rather than "there is".

Here are the forms of "there" in the Simple Present.

There is/There are is a common phrase in English, used to indicate that something ?exists? or is in a certain location. The main subject follows the verb when there is/are is used.

There is an apple on the table.

There are some apples on the table.

Other forms of ?be? can also be used with there is/there are.

There will be a party at Bill's house on Saturday.

There were four witnesses at the crime scene.

There have been two robberies in the last five months.

Contractions are possible, but they are mostly used informally in speech.

There's a fly in my soup.

There're plenty of oranges left.

There'll be a lot of people in attendance.

There's is by far the most common contraction, and it is sometimes used inadvertently with plural subjects by native speakers.

There's ten people outside!

Since the expression there is/are usually has no equivalent in other languages, students sometimes use have instead.

Have a lot of food on the table.
It has a lot of food on the table.
There have a lot of food on the table.
There is a lot of food on the table.

Verb to be

-The verbs am, is, are, was, and were are all forms of the verb be.

-The verb be does not show action. It tells what someone or something is or is like.

The verbs 'am', 'is', and 'are' tell what someone or something is now.

I am a painter.
He is a painter.
You are a painter

Was and were tell what someone or something was in the past.

-She was an artist.
-You were an artist.

-They were all artists.
-You were all artists.

Use am, is, and was with I, she, he and it.

-I am                         -it is                      -I was
-I was                      -she is                     -she was
-she was                 -he is                       -he was

-it was

is/am/are + was/were = เป็น อยู่ คือ

V.to be - is am are

V.to be ได้แก่ is am are ทั้งหมดแปลว่า เป็น,อยู่,คือ

is ก็แปลว่า เป็น,อยู่,คือ
am ก็แปลว่า เป็น,อยู่,คือ
are ก็แปลว่า เป็น,อยู่,คือ

แต่ทั้ง 3 คำนี้ก็มีความแตกต่างในการใช้งาน ต้องจำให้ดีนะครับ

is ใช้กับประธานเอกพจน์ เช่น He She It

Ex. He is a doctor.
เขาผู้ชายเป็นคุณหมอ

am ใช้ได้กับประธานแค่ I เท่านั้น
I am a student.
ฉันเป็นนักเรียน

are ใช้กับประธานพหูพจน์ เช่น You , We , They
We are boys.
พวกเราเป็นเด็กผู้ชาย
