Fact vs. Opinion

What is a Fact? (ข้อเท็จจริง)

A fact (ข้อเท็จจริง) is a statement that is true and can be proven (พิสูจน์).

Examples:

  • There are 60 minutes in an hour.
  • The capital of Japan is Tokyo.

Fact vs. Opinion

What is an Opinion? (ความคิดเห็น)

An opinion (ความคิดเห็น) is what someone thinks (คิดว่า) or feels (รู้สึก). It cannot be proven true or false.

Examples:

  • That new song is fantastic.
  • Traveling by train is more relaxing than flying.

Fact/Opinion: Comprehension Check

1. Which sentence is a FACT?

Correct! It can be proven that a square has four equal sides.
Not quite. This is what someone thinks or feels, which is an opinion.

2. Which sentence is an OPINION?

Excellent! Whether a book is "interesting" is what someone feels.
Try again. This statement can be proven true or false, so it is a fact.

Verbs: Main & Helping

Main Verbs (กริยาแท้)

The main verb shows the most important action (การกระทำ) or state of being (สภาวะ) of the subject.

Examples:

  • We study English. (action)
  • He is tired. (state of being)

Verbs: Main & Helping

Helping Verbs (กริยาช่วย)

A helping verb (กริยาช่วย) comes before the main verb to help it. Common helping verbs are 'be', 'do', and 'have'.

Examples:

  • They are waiting for the bus. ('are' helps 'waiting')
  • She does not understand the lesson. ('does' helps 'understand')

Verbs: Main & Helping

'be', 'do', 'have' as Main Verbs

Sometimes, 'be', 'do', and 'have' are the only verbs in a sentence. When this happens, they are the main verb.

Examples:

  • I am a student. (main verb)
  • You do a great job. (main verb)
  • We have a new car. (main verb)

Verbs: Comprehension Check

1. In "She is kind," the word 'is' is a...

Correct! 'is' is the only verb, so it's the main verb.
Incorrect. There is no other verb for 'is' to help.

2. In "They are playing games," the word 'are' is a...

Yes! 'are' helps the main verb 'playing'.
Try again. The main action verb is 'playing'. What is 'are' doing?

3. In "He did not go," the word 'did' is a...

Perfect! 'did' is helping the main verb 'go' to form a negative sentence.
Think again. The main action is 'go'. What is 'did' doing in the sentence?

The Simple Present Tense

We use the simple present for things that happen regularly or are always true.

  • Habits / Routines (นิสัย / กิจวัตร): I drink coffee every morning.
  • Facts (ข้อเท็จจริง): The Earth is round.

Simple Present: Subject-Verb Agreement

The subject (ประธาน) and verb must agree (สอดคล้อง).

Rules:

  • For I / You / We / They, use the base form of the verb. (e.g., walk, eat, play)
  • For He / She / It, add -s or -es to the verb. (e.g., walks, eats, plays)

Simple Present: 3rd Person Spelling

  • Most verbs: add -s (work → works, live → lives)
  • Ends in -s, -sh, -ch, -x, -z: add -es (miss → misses, wash → washes)
  • Consonant + y: change y to -ies (study → studies, try → tries)
  • Vowel + y: add -s (play → plays, enjoy → enjoys)

Simple Present: Comprehension Check

1. My brother ______ video games every day.

Correct! The subject is 'My brother' (He), so we add -s.
Not quite. Remember the rule for He/She/It.

2. The teachers at our school ______ very hard.

Perfect! The subject is 'The teachers' (They), so we use the base form.
Incorrect. The subject 'teachers' is plural (They).

3. A pilot is a person who ______ airplanes.

Excellent! The word 'fly' ends in consonant + y, so we change y to -ies.
Check the spelling rule for verbs ending in consonant + y.

The Present Progressive Tense

We use the present progressive (ปัจจุบันกาลต่อเนื่อง) for actions that are happening now (กำลังเกิดขึ้นตอนนี้).

Structure:

Subject + am/is/are + verb-ing

Present Progressive: Usage

Look for signal words that mean "now".

  • Look! That dog is wearing a funny hat.
  • Please be quiet. My father is sleeping.
  • I can't talk right now, I'm eating dinner.

Present Progressive: Check

1. Listen! Someone ______ the piano.

Yes! "Listen!" tells us the action is happening now.
Incorrect. The word "Listen!" signals an action happening right now.

2. "Where are the children?" "They ______ in the garden."

That's right! The subject is 'They', so we use 'are' + verb-ing.
Not quite. The subject is 'children' (They). Which form of 'be' should you use?

3. He can't come to the phone because he ______ a shower.

Correct! "He can't come to the phone" means he is busy doing something right now.
Think again. The first part of the sentence tells us why he is busy *right now*.
