kèfángfúwù jǐ diǎn jiéshù?

Chinese usually puts the topic or subject first, then the time question, then the verb.

So the structure here is:

• 客房服务 = room service
• 几点 = at what time
• 结束 = end

So it follows a very normal Chinese pattern:

[thing being talked about] + [when] + [verb]

That is why 客房服务几点结束？ sounds natural.

A very literal breakdown is:

• Room service
  • what time
    • ends?

English uses a different word order, so it becomes:

• What time does room service end?

客房服务 means room service in a hotel.

It is made up of:

• 客房 = guest room / hotel room
• 服务 = service

Together, 客房服务 refers to the service provided to hotel rooms, especially food or assistance ordered to the room.

In real hotel contexts, this is a very common term.

几点 literally means what point/hour and is the normal way to ask what time when you want a clock time.

So:

• 几点结束？ = What time does it end?

This is especially appropriate when asking for a specific time such as:

• 9 o’clock
• 10:30
• midnight

If you used 什么时候, the meaning would be broader:

• 客房服务什么时候结束？ = When does room service end?

That is also correct, but 几点 sounds more specifically like you want the exact time on the clock.

点 is the measure word used for o’clock when telling time.

Examples:

• 三点 = 3 o’clock
• 八点半 = 8:30
• 几点 = what time / how many o’clock

So in 几点, the 几 means how many / which, and 点 tells you the question is about the time on the clock.

Chinese does not need a helper verb like English do/does/did to form questions like this.

English says:

• What time does room service end?

Chinese simply says:

• 客房服务几点结束？

Chinese often forms this kind of question just by using a question word like:

• 谁 = who
• 什么 = what
• 哪儿 = where
• 几点 = what time

So once 几点 is in the sentence, it is clearly a question.

Yes. 结束 is a verb here, and it means to end or to finish.

In this sentence:

• 客房服务几点结束？
• At what time does room service end?

A few more examples:

• 会议几点结束？ = What time does the meeting end?
• 电影已经结束了。 = The movie has already ended.

结束 can also be used in other grammar patterns, including as a transitive verb in some contexts, but here it works simply as end.

Yes, this sentence is natural and understandable.

客房服务几点结束？ is a normal, concise way to ask the question.

Native speakers might also say:

• 客房服务到几点？ = Until what time is room service available?
• 客房服务营业到几点？ = Until what time does room service operate?
• 请问，客房服务几点结束？ = Excuse me, what time does room service end?

These are all natural.
The original sentence is perfectly fine, especially in a hotel situation.

They are similar, but the focus is a little different.

• 几点结束 = What time does it end?
• 到几点 = Until what time?

For example:

• 客房服务几点结束？
• 客房服务到几点？

Both could be used in a hotel.
But 到几点 is often a little more conversational when asking about service hours.

So if you want to sound especially natural in daily speech, 客房服务到几点？ is very common.

The dictionary tones are:

• 几 = third tone (jǐ)
• 点 = third tone (diǎn)

But when two third tones come together, the first one usually changes in pronunciation. So 几点 is commonly pronounced more like:

• jí diǎn

This is a tone sandhi rule.

So:

• written tones: jǐ diǎn
• spoken tones: often closer to jí diǎn

Learners should still remember the dictionary forms, but be aware that native speech changes the first third tone.

Yes, you can.

• 客房服务几点结束？
• 客房服务几点钟结束？

Both are correct.

The version with 钟 can sound slightly fuller, but in everyday speech people very often just say 几点.

So for most situations:

• 几点 is simple and natural
• 几点钟 is also fine

No. Standard written Chinese normally does not put spaces between words.

So it would normally be written as:

客房服务几点结束？

The spaces in learning materials are often added to help beginners see the parts more clearly:

• 客房服务
• 几点
• 结束

But in real Chinese writing, you should expect to see it written without spaces.

Yes. A very common way is to add 请问 at the beginning.

For example:

• 请问，客房服务几点结束？

This means something like:

• Excuse me, what time does room service end?

You could also ask:

• 请问，客房服务到几点？

That sounds polite and natural in a hotel.

Not always. The pronunciation of 几 depends on the word and meaning.

In this sentence:

• 几 means how many / what
• so it is pronounced jǐ

Examples:

• 几点 = what time
• 几个人 = how many people

But in words like 几乎, it is pronounced jī.

So for this sentence, the correct reading is definitely jǐ.
