qǐng nǐ gěi wǒ fùyìn yí fèn bàogào.

In this sentence, 请 is being used to make a polite request, like please in English.

So 请你 + verb means please do... or would you please...

It is not translated word-for-word as please you in natural English, but that is roughly how the Mandarin structure works:

• 请 = please / kindly
• 你 = you

So 请你给我复印一份报告 means Please photocopy a report for me.

It is polite, but it can still sound fairly direct depending on your tone and relationship with the person.

For example:

• 请给我复印一份报告。 = polite request
• 请你给我复印一份报告。 = polite, but slightly more pointed because 你 is stated explicitly

In many everyday situations, this is completely normal. But if you want to sound softer, people often say:

• 请帮我复印一份报告。
• 麻烦你帮我复印一份报告。

Those often feel a little more natural in casual polite speech.

Here, 给 does not mainly mean to give in the usual sense.

In this sentence, 给我 means for me or on my behalf. It marks the person who benefits from the action.

So:

• 给我复印 = photocopy it for me

A useful pattern is:

• 给 + person + verb

Examples:

• 给我拿一下。 = Get it for me.
• 给他打电话。 = Call him.

So in your sentence, 给我 tells us who the photocopying is for.

Mandarin usually puts the beneficiary before the main verb in this kind of structure.

So the pattern is:

• 给 + person + verb + object

That is why you get:

• 给我复印一份报告

Not:

• 复印给我一份报告

To an English speaker, this can feel unusual because English often puts for me later:

• Please photocopy a report for me.

But in Mandarin, 给我 commonly comes before the verb.

复印 means to photocopy or to make a copy of a document.

It is commonly used for paper documents, reports, forms, contracts, and similar things.

Examples:

• 复印身份证 = photocopy an ID card
• 复印文件 = photocopy documents

So in this sentence:

• 复印一份报告 = make a photocopy of a report / photocopy one copy of a report

份 is a measure word, also called a classifier.

In Mandarin, when you count a noun, you usually need:

• number + measure word + noun

So:

• 一份报告 = one report

份 is commonly used for documents and document-like items, such as:

• 一份报告 = a report
• 一份合同 = a contract
• 一份文件 = a document
• 一份工作 = a job

In this sentence, 份 helps count the report as a document.

In this sentence, it is usually understood as one photocopied copy of a report, because the verb 复印 already tells you that copying is happening.

So Mandarin often does not need to separately say a copy of the way English sometimes does.

Also, 份 counts the document as a whole, not the number of pages. A report could be several pages long and still be 一份报告.

This is because of a tone change rule for 一.

By itself, 一 is pronounced yī. But its pronunciation changes depending on the tone of the next syllable.

Before a fourth-tone syllable, 一 becomes yí.

Here:

• 份 is fourth tone: fèn
• so 一份 is pronounced yí fèn

So the pinyin yí is correct in this sentence.

Yes, you can.

• 请你复印一份报告。 = Please photocopy a report.
• 请你给我复印一份报告。 = Please photocopy a report for me.

Adding 给我 makes it clear that the action is being done for your benefit. If that is already obvious from context, it can be omitted.

Yes, and it is very common.

Compare:

• 请你给我复印一份报告。
• 请你帮我复印一份报告。

帮我 means help me / do me a favor by..., so it often sounds a little warmer or softer.

In many real-life situations, 请帮我复印一份报告 may sound more natural than 请你给我复印一份报告.

Yes. 一下 often softens a request and makes it sound less abrupt.

For example:

• 请你给我复印一下报告。
• 请帮我复印一下这份报告。

Here, 一下 does not literally mean one time. It often just makes the request sound lighter and more polite.

So if you want a softer tone, 一下 is very useful.
