There are 2 kinds of verbs given in Thai - English Dictionary.
To + verb (to meet, to see, to find, to cut, etc.)
To be + verb ( to be noisy, to be still, to be silent, to be angry, etc.)
What's the different ?
***** NOT A TEACHER / ONLY MY OPINION *****
Suthipong Worasarn,
I understand how confusing a word such as "infinitive" can be --
even to us native speakers.
(1) In modern English, the word "infinitive" often refers to the form of
verb that you find in a dictionary. For example, the dictionary lists
the word as
eat. That is the infinitive.
(a) I can use the infinitive like this: I can
eat three hamburgers.
(b) I can also use the infinitive like this: I want
to eat three hamburgers.
Many infinitives have the preposition "to" in front.
(c) Many infinitives show action: eat, play, talk, sleep, etc.
(d) Some infinitives do not (usually!!!) show action:
be, appear, seem,
etc.
(e) With action verbs, you often need an object:
eat
ice cream
play
soccer
(f) Verbs such as
be do not (usually!!!) show action. They
describe:
I am
old. ("old," an adjective, describes me.)
You are a
student. ("student," a noun, tells something about you.)
Verbs such as
be are usually called linking verbs because they
link (connect) the subject (I) with the word (old). In some
languages, people say "I old." But in English, we have to have a
verb: I
am old.
Please remember:
be is a verb. We can use it with "to" or no "to":
You want
to be a good student.
I may
be late today.
If you have any other questions, please post them. The people here
are very happy to help you.
Thank you
