Hello 

I've ran into a problem. I can't figured out when to use "do" or not. I will give you some examples so you understand what I mean.

Waiter: Hello, Can I help you?

Kim: Yes, I'd like to have some lunch.

Waiter: Hello, Can I help you?

Kim: Yes, I like to have some lunch.

Which one of them is correct? And why?

Earlier today, when I ate breakfast I heard the fantastic song "If I were a boy" by beyonce. I noticed that she sings "I'd roll out of the bed in the morning. Why?" 

"If I were a boy, even just for a day 

I'd roll out of bed in the morning"

I'm sorry for my bad language, but I hope you will understand!!

Best wishes from sweden!!!

Welcome to English Forums!

'd doesn't mean do. It means would.

To say you want something, you use the idiom "would like", not just "like".

I would like to have some lunch.
I would like to travel in Mexico.
I would like to see that movie.


I would can be expressed as I'd:

I'd like to [have some lunch / travel in Mexico / see that movie].

___

I'd roll out of bed = I would roll out of bed.

Hi, Uberanton, welocome to EnglishForward. Emotion: smile
uberantonI've ran into a problem. I can't figured out when to use "do" or not. I will give you some examples so you understand what I mean.

Waiter: Hello, Can I help you?

Kim: Yes, I'd [would] like to have some lunch= I want to order lunch. "Would" is a modal here and expresses politeness and preference.

Waiter: Hello, Can I help you?

Kim: Yes, I like to have some lunch= Having lunch is a thing I like, and I often do it. You say what you love to do, not making an order. It sounds strange. like + -to infinitive means in generall what you like in general.

What do you like? I like to swim.
(I like and I do it when I can)
What would you like to have tommorow's dinner? I'd like fried fish and fresh salad. (That's what I prefer.)


Earlier today, when I ate breakfast I heard the fantastic song "If I were a boy" by beyonce. I noticed that she sings "I'd roll out of the bed in the morning. Why?"

"If I were/was a boy, even just for a day

I'd [would] roll out of bed in the morning" It's unreal situation called The Second Condition (she will never be a boy she just imagine it).

If I were a doctor, I would make a lot of operations. (But I am not a doctor)

I'm sorry for my bad language, but I hope you will understand!!

When do you want to use "do"?
Students: Are you brave enough to let our tutors analyse your pronunciation?
