Comments
In this causative sentence, what does the verb "has had" denote? Whether it denotes the continuation of action for a certain period or repetition of the same action in regular intervals.
He has had his car repaired.
The second doubt is about the usage of "having" in continuous form. Does the meaning of the word "having" in this sentence have the same meaning as "taking"? Can we replace it with the word taking?
I was having my hair cut when my phone rang.
Hi Mussorie,
In your first sentence, it's probably a single action with a result in the present. (The result is that the car is now repaired.) We would need to know the context when somebody said this sentence to know for sure.
In your second sentence, the meaning is similar to 'receiving' or 'getting'. No, we can't replace it with 'taking' because the correct phrase is 'have (my) hair cut', not 'take (my) hair cut'. Also, this meaning of 'have' is not specific to the continuous form. It can be used in other verb forms too (e.g. I have my hair cut every month).

Thank you, Kirk.
Then, is the phrase "watching the game" in the sentence acting as an object complement to the word busy?
Hello Mussorie,
Yes, it's a complement of the adjective 'busy', though I'm not sure I'd call it an 'object' complement since 'is' is a linking verb.
All the best,

Hello Peter, this long question (different questions) requires your patience to answer.
1.What is the difference between the two sentences?
1.He is busy watching the game ( correct)
2.He is busy in watching the game (incorrect)
Why the second statement is incorrect?
2.Is this statement correct?
Watching the game, Ravi is busy.
3.I am a bit confused after seeing this statement because the present participle (going) in the participle phrase is not modifying the subject in the main clause.
Could you please elaborate on this?
Statement: Going by recent studies and anecdotal field reports, food inflation has impacted the health of the poor.
Hello Mussorie,
1. That's right -- the second statement is not correct. The structure we use here is 'to be busy doing something' -- no preposition is used between 'busy' and the '-ing' form.
2. I would recommend inverting the two phrases ('Ravi is busy watching the game'), which sounds much more natural. The sentence as it is written could be a little confusing, since 'watching the game' isn't really working in the way a participle clause usually does.
3. I'm afraid I can't explain the writer's choice here, but it might help to think of it as beginning with 'If we look at recent studies ...'. I would avoid writing the sentence like this for the reason you mention.

Peter, could you please answer the already posted question?
Hi team,
I want to know one more thing.
For example, when I write these two sentences;
a)We waited ages for a table.
b)We waited ages to get a table.
Are there any diffrences between those two sentences? Their purpose is the same which is 'table'.
Thanks a lot!
Hi Nevı,
In this context I see no difference,

Hi brilliant team,
I want to learn one more thing.
When I sometimes saw a verb pattern, which is especially "verb+somebody/something +to do something" I am confused about "to+infinitive" is a part of a pattern or infinitive of purpose.I mean
For example "I used computer to look my school grades."
-use something to do something- is one of the patterns of use, but it also have meaning of purpose.
Is "to infinitive" part of the pattern or infinitive of purpose? Could you explain, please?
