qǐng bǎ jiùwù dǎbāo.

把 marks the noun that is being directly acted on and places it before the verb.

In 请把旧物打包, the thing being handled is 旧物. The pattern is:

请 + 把 + object + verb/action

So here:

• 请 = please
• 把旧物 = take the old items / as for the old items
• 打包 = pack them up

This is called the 把-construction. It is very common when the speaker wants to emphasize what happens to the object.

That is because this sentence uses the 把-construction.

A more basic Mandarin order is usually:

Verb + object

But with 把, Mandarin changes the order to:

把 + object + verb

So instead of something like pack the old items, Mandarin says more like:

take the old items and pack them

This structure is especially common when:

• the object is specific
• the action clearly affects it
• the result or handling of the object matters

So 请把旧物打包 sounds very natural because the sentence is about what should be done with the old items.

Here, 请 means please.

请 can have several meanings in Mandarin, including:

• please — as in making a polite request
• invite — as in 请客 (to treat/invite someone)
• ask — in some formal or set expressions

In 请把旧物打包, it is clearly the polite-request meaning: please.

So the sentence is an instruction or request, not an invitation.

旧物 literally means old things/items.

Breakdown:

• 旧 = old, used
• 物 = thing, object

Depending on context, 旧物 can mean:

• old belongings
• used items
• old possessions
• old stuff

It sounds a bit more formal or written than everyday casual words like:

• 旧东西 = old things
• 旧衣物 = old clothes/items of clothing
• 旧货 = secondhand goods

So 旧物 is understandable and natural, but it has a slightly tidier, more formal feel than just saying 旧东西.

Here, 打包 means to pack up or to bundle up.

In this sentence, it means to gather the old items together and put them into bags, boxes, or some kind of package.

A useful thing to know is that 打包 has more than one common use:

1. pack up / bundle up items

   • like in this sentence

2. pack food to go / takeout

   • for example, at a restaurant, 打包 often means box it up to take home

So the meaning depends on context.
With 旧物, it clearly means pack up the old belongings/items.

Yes, you can, but it sounds a bit less natural in many contexts than 请把旧物打包.

Compare:

• 请把旧物打包。
• 请打包旧物。

Both are understandable. But 把 is often preferred when:

• the object is definite/specific
• the action changes or handles the object directly
• the speaker wants to focus on what should be done with that object

So 请把旧物打包 feels more standard for a clear instruction like Please pack up the old items.

Without 把, the sentence is still grammatical, but sometimes it can sound a little less focused or a bit more terse depending on context.

Yes. Mandarin often leaves out the subject when it is obvious from context.

In 请把旧物打包, the subject is not stated, but it is understood as something like:

• you
• someone here
• the person being addressed

So the full sense is:

• Please pack up the old items.

Mandarin commonly omits subjects in commands, requests, and conversations when they are already clear.

It is a polite request or polite instruction.

Because it begins with 请, it softens the sentence and makes it more courteous.

Compare the tone:

• 把旧物打包。 = Pack up the old items.

  • more direct, more like a plain command

• 请把旧物打包。 = Please pack up the old items.

  • more polite

So grammatically it is imperative in function, but socially it sounds courteous.

It can mean one or more, depending on context.

Mandarin nouns usually do not have separate singular and plural forms the way English does. So 旧物 could refer to:

• an old item
• old items
• old belongings in general

In real usage, context tells you which meaning is intended.
In a sentence like 请把旧物打包, it often feels more like old items / old belongings as a group.

If you want to make plurality clearer, Mandarin often uses context, numbers, or words like:

• 这些旧物 = these old items
• 一些旧物 = some old items

The pinyin is:

qǐng bǎ jiùwù dǎbāo

Tone pattern:

• 请 qǐng — 3rd tone
• 把 bǎ — 3rd tone
• 旧 jiù — 4th tone
• 物 wù — 4th tone
• 打 dǎ — 3rd tone
• 包 bāo — 1st tone

A natural rhythm is:

qǐng | bǎ jiùwù | dǎbāo

A couple of tips:

• 旧物 is pronounced as one word: jiùwù
• 打包 is also one word: dǎbāo
• Even though 请 and 把 are both 3rd tone, in natural speech the first one is often said with a half-3rd-tone shape rather than a full dip

So it will often sound more like:

qǐng bá jiùwù dǎbāo in flowing speech

That is normal connected pronunciation.

旧物 is fine, but in everyday speech many native speakers might more often say:

• 旧东西 = old things
• 旧衣物 = old clothes/items of clothing
• 不用的东西 = things you no longer need
• 旧物品 = old items/articles

So 旧物 is correct and natural, but it can sound a little more concise, neat, or slightly written depending on the situation.

For example:

• 请把旧东西打包。
  sounds very everyday

• 请把旧物打包。
  sounds a bit more compact and possibly a little more formal

Because this sentence is a request/instruction, not a statement that the action has already been completed.

• 请把旧物打包。 = Please pack up the old items.
  
  • asking someone to do it

If you say:

• 请把旧物打包了。

that usually sounds less natural on its own as a simple request. 了 often relates to completion or a change of situation, and it needs the right context.

For a straightforward polite instruction, 请把旧物打包 is the normal form.
