车管所 means the vehicle administration office or motor vehicle bureau. It is where people handle things like:

• vehicle registration
• license plates
• driver’s license paperwork
• ownership transfers

It is short for 车辆管理所. In everyday Chinese, people often use the shorter 车管所.

正在 shows that an action is in progress right now.

So:

• 车管所正在审核我的申请材料。 = The vehicle administration office is currently reviewing my application materials.

It is similar to English is reviewing.

A useful comparison:

• 审核我的申请材料 = review my application materials
• 正在审核我的申请材料 = be reviewing my application materials right now

Yes.

• 车管所审核我的申请材料。

This is grammatically fine, but it sounds less clearly focused on the ongoing action. It could sound more like a general statement, depending on context.

Using 正在 makes it clear that the review is happening at this moment or during the current period.

Mandarin word order is usually:

Subject + time/aspect marker + verb + object

So here:

• 车管所 = subject
• 正在 = progressive marker
• 审核 = verb
• 我的申请材料 = object

This matches a very common Chinese pattern.

A literal structure would be:

• The vehicle office + is currently + reviewing + my application materials

So the word order is actually quite close to English in this sentence.

的 is a very common particle that links a modifier to a noun.

Here:

• 我 = I / me
• 我的 = my
• 申请材料 = application materials

So 我的申请材料 means my application materials.

You can think of 的 here as the marker that turns 我 into a possessive phrase.

Examples:

• 我的车 = my car
• 我的朋友 = my friend
• 我的申请材料 = my application materials

申请材料 means application materials, application documents, or paperwork for an application.

It is a noun phrase made from:

• 申请 = to apply / application
• 材料 = materials, documents, information provided

In Chinese, nouns usually do not have to show singular/plural the way English does. So 申请材料 can refer to:

• one set of documents
• multiple documents
• the application paperwork as a whole

The exact number is understood from context.

They are related, but not identical.

• 审核 = to review and verify, especially in an official or formal process
• 检查 = to inspect, check, examine
• 审查 = to examine carefully, often in a more formal, strict, or institutional way

In this sentence, 审核 is a very natural choice because an office is reviewing submitted paperwork.

So 审核申请材料 sounds more official and appropriate than simply 检查申请材料.

Because 申请材料 works as a fixed noun phrase meaning application materials.

So the structure is:

• 我的 = my
• 申请材料 = application materials

Together:

• 我的申请材料 = my application materials

You should not try to split it like English sometimes does. Chinese often builds compounds first, then adds modifiers to the whole compound.

Yes, sometimes.

You may hear:

• 车管所在审核我的申请材料。

This can also mean The vehicle administration office is reviewing my application materials.

But there is a difference in feel:

• 在 + verb = progressive, often a bit lighter or more conversational
• 正在 + verb = progressive with stronger emphasis on currently / right now
• 正在 can sound a bit more formal or more clearly focused on the ongoing action

In this sentence, 正在 fits well because the situation is official.

Yes. A passive version would be:

• 我的申请材料正在被车管所审核。

This means:

• My application materials are currently being reviewed by the vehicle administration office.

This is grammatical, but the original active sentence is often more straightforward and natural in everyday use.

Chinese does use passive sentences with 被, but it does not rely on them as heavily as English does.

Yes, a few useful ones:

• 车 = chē (1st tone)
• 管 = guǎn (3rd tone)
• 所 = suǒ (3rd tone)
• 正 = zhèng (4th tone)
• 在 = zài (4th tone)
• 审 = shěn (3rd tone)
• 核 = hé (2nd tone) in 审核
• 申 = shēn (1st tone)
• 请 = qǐng (3rd tone)
• 材 = cái (2nd tone)
• 料 = liào (4th tone)

A very common point: 核 is pronounced hé in 审核.

Also, when speaking naturally, the sentence will flow together, so do not pause too much between each word.

It is fairly neutral to formal.

That comes mainly from words like:

• 车管所 — an official institution
• 审核 — formal review
• 申请材料 — administrative paperwork language

So this is the kind of sentence you would expect in:

• official updates
• customer service messages
• administrative conversations
• written notices

It is not overly stiff, but it is definitely not casual chat language.

A native speaker would understand it very naturally as:

• the office has received the documents
• the review process is currently underway
• no final decision has been made yet

So the sentence implies an ongoing administrative process, not completion.

If the review were already finished, Chinese would more likely use something else, such as a completed-action form rather than 正在.
