Welcome to Grammar in Use!

Hello there! In this lesson, we are going to learn how to use special "helper" words like can, should, and going to. We will also learn how to use and, but, and because to glue our sentences together. These words help us tell stories, give advice, and talk about our plans. Let's get started!

1. Using "Can": Ability and Requests

The word can is a very busy word! We use it to talk about what we are able to do or to ask for permission.

Ability (What you can do)

We use can to show that we have the skill to do something.

  • I can swim. (ฉันว่ายน้ำเป็น)
  • Birds can fly. (นกบินได้)

Asking for Something

We use can to ask for things or permission politely.

  • Can I have some water, please? (ขอน้ำหน่อยได้ไหมครับ/ค่ะ)
  • Can you help me? (คุณช่วยฉันหน่อยได้ไหม)

Quick Tip: After can, the action word (verb) stays very simple. No "s", no "ing"! Just can run, can jump, and can eat.

2. Using "Should": Giving Advice

We use should when we want to give a friendly suggestion or tell someone the right thing to do. (In Thai: ควรจะ)

  • You should eat vegetables. (คุณควรทานผักนะ)
  • We should listen to the teacher. (พวกเราควรฟังคุณครู)
  • You should wash your hands. (คุณควรล้างมือ)

Memory Aid: Think of should as the "Doctor Word." Doctors often give advice using should to help us stay healthy!

3. Using "Going to": Future Plans

When you have already decided to do something in the future, use be + going to.

How to build it:

  • I am going to...
  • He/She/It is going to...
  • You/We/They are going to...

Examples:

  • I am going to play football tomorrow. (ฉันจะไปเล่นฟุตบอลพรุ่งนี้)
  • She is going to visit her grandmother. (เธอจะไปหาคุณย่า)

Did you know? We use going to for things we have already planned. It’s like a promise to yourself!

Key Takeaway: Can is for ability, should is for advice, and going to is for future plans.

4. Linking Words: And, But, and Because

Linking words are like "glue." They turn short sentences into longer, more interesting ones (Compound Sentences).

And (และ)

Use and to join two similar ideas together.

  • I like apples and I like bananas.
  • I have a pen and a pencil.

But (แต่)

Use but to join two different or opposite ideas.

  • I like cats, but I don't like dogs.
  • The elephant is big, but the mouse is small.

Because (เพราะว่า)

Use because to give a reason. This word answers the question "Why?". (Note: This is usually for students in Grade 5 and 6).

  • I am happy because I got a gift. (ฉันมีความสุขเพราะฉันได้ของขวัญ)
  • She stayed home because it was raining. (เธออยู่บ้านเพราะฝนตก)

Common Mistakes to Avoid

Don't worry if this seems tricky! Just watch out for these small errors:

  • Mistake: I can to swim. (Wrong!)
    Correct: I can swim. (No "to" after can!)
  • Mistake: He going to play. (Wrong!)
    Correct: He is going to play. (Don't forget the "is/am/are"!)
  • Mistake: I like cake but I like candy. (Confusing!)
    Correct: I like cake and I like candy. (Use "and" for things that go together.)

Quick Review Quiz (Mental Check)

Try to fill in the blanks in your head:

  1. I ______ fly a kite. (Ability)
  2. You ______ study for the test. (Advice)
  3. I am ______ ______ eat pizza for dinner. (Plan)
  4. I like milk ______ I don't like coffee. (Linker)

(Answers: 1. can, 2. should, 3. going to, 4. but)

Summary: You can now talk about what you can do (can), give advice (should), talk about your future (going to), and connect your thoughts (and, but, because). You are doing a great job! Keep practicing these words in your daily life.
